KC/5 Safety Notice!
PLEASE FOLLOW THESE INSTRUCTIONS CAREFULLY TO AVOID POSSIBLE
INJURY!
Kajaani Process Measurements’ KC/5 standard retractable version is designed for applications where line pressure is
less than 10/16 bar (150/232 pounds per square inch (psi). A special, non-retractable model is available for use in
applications with higher line pressures.
The KC/5 is shipped in completed sub-assemblies. All safety related components are checked and verified to work
correctly, before the product is shipped from our factory. The Customer is responsible for proper, safe installation by
following the procedures outlined in the KC5 “Instruction Manual” included with each KC/5 shipment.
Special care must be taken to ensure that the “Locking Ring” part #H41040131V1.0, part of the installation hardware,
is properly tightened at all times according to the “Instruction Manual”.
If the “Jack Assembly” part number A41040175V1.0, has been damaged and neither the “Seal Sleeve Assembly” nor
the “Locking Ring” is secured according to the “Instruction Manual”, Section 3.5, the KC/5 Sensor may be propelled
out of the line by the line pressure causing possible injury.
The KC/5 Sensor must be securely locked into place with the “Locking Ring” after every instance where the sensor is
removed and re-inserted into the process, or after the “Seal Sleeve Assembly” is disassembled and re-assembled. All
persons who work on the KC/5 must follow all instructions in the “Instruction Manual”, Section 3.5, and in this Safety
Notice, to eliminate any chance for injury when working on the KC/5.
The “Locking Ring” and the “Jack Assembly” are critically important to the safe use of the KC/5 transmitter. Each
must be properly attached, and securely tightened in place, while the sensor is inserted into the process line. When the
Gate Valve is opened, the Sensor may be withdrawn from the line by slightly loosening the “Locking Ring”. The “Jack”
then withdraws the Sensor from the process so the Gate valve may be closed. Only after the closed Gate Valve has
isolated the line pressure from the withdrawn Sensor, is it safe to loosen the “Jack Assembly” and remove the
“Locking Ring”.
It is critically important to make certain that both the “Locking Ring” and the “Jack Assembly” are secured according to
the procedures outlined in the “Instruction Manual”, Section 3.5, during initial installation and before each attempt to re
- insert the Sensor into the process line.
Note! Make sure all Bolts and Nuts are tightened properly before opening the gate valve.

1.4 KC/5 system description
The KC/5 consists of the Sensor Unit with the Mounting Assembly and the Display Unit (See figure 1-2).
KPM offers five (5) installation options:
1. KPM Standard Measurement Chamber with Gate Valve and installation jack.
2. BTG MEK adapter with Gate Valve and Installation Jack.
3. Flange installation with KPM Measurement Chamber without Gate valve and Installation Jack.
4. Mounting bracket for mounting on open vessel (i.e. stuff box or saveall drop chest).
5. Flanged Adaptor for ISO-torq installation without KPM measurement Chamber or new Gate Valve, and
new Installation Jack
The Measurement Chamber is welded to the process pipeline (min. diameter 150mm, 6”). The DN80 (3”)
gate valve is mounted to the Measurement Chamber. Sensor probe is inserted into the process by the
heavy duty insertion jack which is mounted to the gate valve assembly.
The display unit is connected to the sensor unit by a 10 m (33 ft) long, shielded 10-conductor cable
(maximum length available is 30 m (100 ft)). The cable includes a connector that can be quickly coupled to
the sensor unit. Display unit is powered by 85-264 VAC/47-63 Hz and supplies 12/48 VDC to the sensor. All
external electrical connections are made in the display unit (4 – 20 mA analog output, binary inputs). The
sensor motor can be interlocked with “stock pump running” information (pump) via binary input in display
unit.
Figure 1-2. The KC/5 sensor unit with the display unit.
1.5 Measuring principle
The KC/5 sensor unit rotates the sensing element (see Figure. 1-3) in the pulp slurry. The slurry resists the
movement. To overcome this resistance, a torque force is created. The higher the consistency, the greater
September 2006
W41040300 V3.01
Page 6 of 67
is the force. The KC/5 measures the torque and converts this torque measurement into a consistency
measurement value.
KC/5 uses a “direct drive” servomotor. The “stator” is mounted in the body of the sensor unit, and the “rotor”
integrated into drive shaft assembly. There is no drive belt or gearbox in the KC/5 design.
The motor rotates two optical discs. One, the drive disc, is attached to the drive shaft. The other, the
moment disc is coupled to the drive disc with coil springs. The moment disc is mounted to the moment shaft
– the sensing element is located in the opposite end of moment shaft.
When the drive shaft rotates, the springs force the moment disc to follow. The force-resisting movement
varies, depending upon the consistency of the slurry within which the sensing element rotates. With higher
resisting force, the springs stretch more and the moment disc lags farther behind the drive disc. At less
resistance, discs follow closer to each other. The discs rotate at the same speed. As Cs increases,
however, the “phase shift” between the two discs increases in direct proportion to the degree of torque
applied.
Figure 1-3. Measuring principle
A high-resolution optical sensor detects the Phase Shift of the windows as consistency changes.
Measurement electronics convert the optical signal into a calibrated torque value. The KC/5 system
measures torque from zero - no torque applied to the sensor element - to a maximum 2000 mNm(170)
ounces per inch. The accuracy is factory calibrated using torque standards. Each KC/5, therefore, has the
same Cs sensitivity, making all sensors interchangeable without re-calibration.
Torque is generated by shear force that changes when a rotating sensing element cuts through a moving
fiber network (see Figure 1-4). As the curve shows, the torque generated by a rotating sensing element is
not linear with consistency, but rather, increases more steeply at higher consistencies.
The measurement algorithm in the KC/5 linearizes the relationship between consistency and the torque
value. The KC/5 then calculates the output consistency as follows:
C% = S * M + Z
Where:

Slope (S) and offset (Z) are grade specific. KC/5 comes with seven pre-calibrated consistency curves that fit

1.6 Sensing element
KC/5 transmitter is provided with the paddle type sensing element as standard (See figure 1-5).
Sensitivity of shear force measurement is directly proportional to the amount of “cutting surface” of a sensor
element.
The paddle-style sensing element has very large cutting surface area providing excellent sensitivity over full
measurement range.
2 Paddle sensing element is for general purpose and provides similar signal as paddle sensing element.
4 Paddle sensing element is used to give additional sensitivity on very low consistencies.
Plane sensing element is stream-lined and is less likely to pick up stringy debris as are typically
encountered in unscreened recycle and “broke-line” applications.
Half-Plane is for medium consistency (>8% Cs) applications.

2. Location and installation requirements
2.1 General notes
The KPM transmitters are designed and manufactured to provide accurate and reliable measurements over
a long period of time. Correct installation will ensure maximum performance and minimum cost of
ownership.
Avoid installing the transmitter around heavy vibration sources (e.g. cavitating or unbalanced pumps).The
KC/5 has two seal water options, Mill seal water or integrated seal water reservoir. Mill seal water is
recommended in applications with fillers and with recycled pulp.
Install a reliable sampling valve close to the transmitter. Poor sampling leads to inaccurate calibration and
underperformance of the measurement. KPM KS- samplers provide consistent and reliable solution for any
sampling application.
2.2 Selecting the optimum measuring site
Selecting the ideal location and installing the KC/5 properly are keys to successful measurement. Look for
the site that:
1: Optimizes the performance of the instrument.
2: Provides clear access for maintenance.
KC/5 rotating type transmitter is installed in the Measurement Chamber. The insertion depth of the sensing
element is adjustable allowing to locate the sensing element to best measuring position also in difficult flow
conditions. See fig. 3.10.
Minimum straight pipe sections for transmitter:
Low consistency 1.5 – 8%:
Calming length Lbefore = 3 * D or 1 m (3 feet) whichever is longer
Calming length Lafter = 1 * D
Medium consistency 8 – 16%:
Calming length Lbefore = 1.5 * D or 0.5 m (2 feet) whichever is longer
Calming length Lafter = 1 * D
The KC/5 rotating consistency is not sensitive for disturbances caused by turbulence, allowing installation
immediately after the process pump when the straight pipe section is not available.

3. Sensor unit and display unit installations
3.1 Process connections
There are 5 alternative process connections:
1. KPM Standard Measurement Chamber with Gate Valve and installation jack. This is the KPM
recommended process connection. See 3.2 for installation instructions
2. Flange installation with KPM Measurement Chamber without Gate valve and Installation Jack
3. Existing BTG measurement chamber (Appendix 3.3 and 3.4)The KPM Adapter fits the Gate Valve
and the Sensor Mounting Assembly to the existing BTG chamber.
4. Mounting bracket for mounting on open vessel or weir (i.e. stuff box or saveall drop chest).
5. Flanged Adaptor for ISO-torq installation without KPM measurement Chamber or new Gate Valve,
and new Installation Jack
3.2 Installing the Measurement Chamber
1. Cut the chamber (Fig. 3-1.) so that the distance from flange to outer surface of pipe is 82 mm/
3,23”, unless cut already by Kajaani Process Measurements.
2. Verify that the curvature of the chamber fits properly over the outside diameter of the pipe.
3. Cut a hole in the side of the pipe to match to the shape of the chamber as shown in figure 3-2. To
prevent fiber debris from collecting on the edge of the cut-out, ensure the edges of the hole are
ground smooth. Debris collected at this location can interfere with proper measurement (See
appendix 1).
4. Place the chamber over the hole in the pipe. Verify that the hole is centered with respect to the
chamber. Fillet weld around the entire perimeter of the chamber to attach the chamber to the pipe.
(See welding drawing appendix 1).

3.5 Insertion of the sensor
Preparing for insertion
1. Check that the inside of seal sleeve is free of dried pulp and debris. Remove any material inside
2. Check that the O-ring inside the seal sleeve are secure and undamaged
3. Lubricate O-ring surfaces with grease to reduce friction (Vaseline or silicone grease can be used for
lubrication)
Inserting the sensor
If the sensor has previously been in use make sure the sensing element and seal sleeve inside are
clean. Every time the KC/5 is taken out of line, the seal sleeve and sensing element should be
rinsed with clean water to remove any pulp and debris.
Note: Before inserting the sensor the first time, please read the chapter 6.2. before insertion to
follow correct setup procedure depending on the application.
Note: To prevent the sensing element from pushing against the gate valve, make sure that the jack
is in FULLY OPEN position.
1. With the gate valve still in the closed position, lift and slide the KC/5 unit into the seal sleeve until the
bolts in the jack can be mounted to the sensor body. (See figure 3-8). The jack must be completely
open.
2. Fasten sensor probe to the insertion jack with two bolts and insert the locking pins to prevent the bolts
from turning by vibration.
3. Connect the seal water to the sensor.
4. Open the gate valve.
5. Jack the sensor in until the insertion depth adjustment ring stops against the locking ring.
6. Fasten the locking screw to lock the sensor safely into its measurement position.
7. Connect the interconnect cable to the Sensor

Safety Check after each insertion to the process line
Safety Warning: Jack and Locking Ring must be secured and attached in place after re-inserting
the sensor.
Proper installation of the locking ring is required to prevent:
1. Injury – secures the sensor in place to keep it from accidently backing out of the process.
2. Sensor Damage – stabilizes the sensor and minimizes vibration that may damage the jack and
the sensor unit.
AT ALL TIMES, IT IS CRITICAL TO ENSURE THAT THE LOCKING RING IS SECURELY TIGHTENED IN
PLACE.
The locking ring secures that the sensor does not come accidentally out from the process and that the
sensor doesn’t vibrate inside installation parts. Excessive vibration can damage the jack and the sensor. It
is important the Locking Ring is securely tightened.

3.7 Seal water connection
KC/5 drive shaft is equipped with mechanical seals (double seal, tandem sealing system). The seal
manufacturers recommend flushing of seals with water to extend the seal life. The water provides flushing,
lubricating and heat transfer.
KC/5 has two alternatives for seal flushing
1. Low pressure water flushing.
2. Self contained seal cooling and lubrication system (reservoir)
3.7.1. Low pressure water flushing
It is recommended to connect flushing water if the water quality is good enough to keep the seal water
system clean. Mechanical seals last longer with seal water when pulp contains fillers. The rate of flow is
limited by the flow regulator. Make sure that seal water flow can be checked and monitored easily.
Recommended water pressure is 1.0 -10 bar (15 -150 psi), max. particle size 200 µm. Flow is 0.5 to 2.0
l/min (0.13 to 0.5 US gal/min) within specified pressure.

W41040300 V3.01
Page 20 of 67
Connect the seal water to the ¼” male fitting of the sensor using flexible ¼” reinforced plastic tube. Flexible
tube must be used to facilitate the move of the sensor.
Install a shut-off valve close to the transmitter. Connect another ¼” reinforced plastic tube to the outlet, and
draw it to the floor drain and fasten it just above the floor outlet so that the flow can be observed.
It is a mandatory to install an anti-siphon prevention tube to prevent siphon phenomena in case of seal
water loss.

3.7.2. Self contained seal water system
The self containing cooling liquid system is optional. This approach is recommended if water quality is poor.
The cooling water reservoir is mounted in the insertion jack and connected with flexible tube to the seal
water inlet. Volume is 1 liter (1/4 US gallon), use drinking water to fill the reservoir if ambient temperature
stays above 0ºC (+32ºF). If freezing conditions are possible, use glycol/water mixture 50/50%
Water reservoir is emptied when ever tubes to the sensor are decoupled. Refill the reservoir before power
to the sensor is turned on.

3.8 Insertion depth adjustment
KC/5 sensor can be installed at adjustable depth into the process. To move the depth adjustment ring,
loosen the set screws, slide the adjustment ring to desired position and relock the set screw again. Figure 310 gives most commonly used values. Unless specified in the order, KC/5 comes with standard depth
adjustment for KPM Installation Chamber. With MEK adapter sensor need to be fully inserted.
Depth adjustment becomes useful if flow pattern or consistency profile changes for one reason or another.
By inserting the sensing element deeper inside one can avoid the layer where consistency profile varies.

Grade names may be edited (see Menu Diagram, Section 5.2). Edited grade names remain in use until
factory reset is activated, at which time, the original factory settings are restored in the language selected.
Factory default values are stored permanently in KC/5 memory.
When the KC/5 is started for the first time, the factory default values are in use. The user may then change
these parameters as necessary. The KC/5 will use the most recent parameters selected for each grade.
2. Select low limit of measurement span
The low limit may be set between 0.00 and 19.99 %/Cs. This value corresponds to output current 4 mA.
Low limit must be smaller than high limit.
3. Select high limit of measurement span
The high limit may be set between 0.00 and 19.99 %/Cs. This value corresponds to output current 20 mA.
High limit must be larger than low limit.
4. Output filter
The user may elect to filter out process noise, or abnormal spikes, from the output signal by using this
function. Filtering time is expressed in seconds (default = 10 seconds).
5. Set clock
Date and time are given in “YYYY-MM-DD and HH:MM” format.
6. Grade selection mode
The user may choose either local selection of grade type or remote selection using binary inputs.

7. Select menu language
Select between English (default) and Finnish.
8. Select sensing element
The user selectable sensing element types are Paddle (default), 4-Paddle and Plane. The user has to select
the element that is installed on the sensor.
9. Error output
The User may select one of four responses when the KC/5 detects an error. These are:
•
NO EFF: measured value is outputted even through the value of output can be erroneous
(default).
•
3.5 mA: analog output goes to 3.5 mA during error.
•
22 mA: analog output goes to 22 mA during error.
•
FREEZE: output freezes on the last accepted measurement value.
See more information from chapter 7.2 - Check alarms.
10. Process stop output
When the “Process stop” input is activated the KC/5 sensor motor stops running. The user can select how
the output behaves in this case. Alternatives are:
•
4.0 mA: analog output goes to 4.0 mA during stoppage.
•
20 mA: analog output goes to 20 mA during stoppage.
•
FREEZE: output freezes on the last accepted measurement value.
•
11. Password
If other than 000 is selected this password is required to move from the main display to the menus. 633
overrides any set password and can be used always.
12. Auto reverse
When auto reverse is activated the motor runs at set interval in reversed direction. There are 3 options to
select from:
•
“OFF”: Motor runs all the time in the same direction
•
“AUTO ZERO”: Motor runs at set interval for a certain time in reversed direction. The measured
reversed torque is used for automatic zeroing of the torque measurement system. The reversed run
frequency and time are set in the “factory settings” menu.
•
“SELF CLEANING”: Motor runs at set interval for a certain time in reversed direction. No
automatic zeroing is done. The purpose to remove wrapped material from the sensing element.
6. Calibration
A separate set of calibration values is needed for each type of sensing element and pulp grade measured.
The KC/5 may be calibrated against laboratory values by taking samples or by choosing values from the
sensor memory.
Initial calibration of KC/5 consists of following steps:
•
A. “Torque Offset”: While the process is running in the normal conditions the motor is run in revered
direction with the sensing element inserted in the measurement position. KC/5 calculates the torque offset
for zeroing the system. Press ENTER to confirm. (See 6.2).
•
B. “Single-Point Calibration”: KC/5 tunes calibration parameters Slope (S) and Zero (Z) based on one
laboratory sample (see Section 6.3).
•
C. “Calibration”: Fine-tuning of the calibration using multiple points is described in Sections 6.4-6.6.
For standard installations, follow Steps A and B.
September 2006
W41040300 V3.01
Page 31 of 67
6.1 Calibration menu
Consistency calibration is made by linearized curve.
Cs = S x M + Z
Cs=Consistency, S = Slope, M = Linearized measurement and Z = Zero.
1. Change zero and slope:
The user can review and adjust the Z and S values from this display setting. Zero Z can be adjusted from 99.99 to +99.99. Slope S can be adjusted from 0.00 to +19.99.
2. Lab values:
The user may review the last 10 samples stored in the memory; including sampling times, measured values,
and lab values. Through this display the new lab values are entered or old values edited.
Use the delete (“DEL”) function to remove old sample..
3. Calibration calculation:
The KC/5 is able to calculate new Z and S values based upon a minimum of three (3) sets of stored
calibration data.
Recommendation: Use a spreadsheet program (e.g. Excel™) to record and track calibration data in place of
using KC/5-aided calculation. The spreadsheet provides the user better visibility to data and simplifies
removing of unreliable information.
4. Start up:
1. Torque Offset: To zero any offset in torque measurement system. Used normally in the initial set up
of the unit
2. Edit torque offset: The zero adjustment offset received in the above procedure can be edited. Used
only in special cases.
3. Target Cs: Used to quickly start-up a new unit. See 6.3 for details.
4. Edit target Cs: To edit the “presumed” consistency. See 6.3. for details
6.2 Torque Offset (Zeroing of the torque measurement system)
A: Low consistency applications below 5% Cs.
Insert the sensor into the process. Make sure that the process is running in the normal operating conditions.
1. With the sensor in-line and the process running, seal water flowing, turn power “On.”
2. Go to “Start up – Torque offset – Meas. Torq. Offset,” and press ENTER.
3. The display asks to “Wait a moment” while it is checking the zero point of the torque measurement
system.
4. Result of the zero check is shown in the display. Press ENTER to complete the zeroing procedure.
Write down the result.
5. Repeat the Meas. Torq. Offset procedure. Compare the results, if difference is bigger than 2mNm,
proceed according the following procedure: B: Medium consistency applications.
B: Medium consistency applications above 5% Cs.
1. Remove the sensor from the process according chapter 7.5, Removal of the sensor, or make sure
the process line is empty or filled with water.
2. Hold the sensor on your lap and make sure the sensing element can rotate freely.
3. Go to “Start up – Torque offset – Meas. Torq. Offset,” and press ENTER.
4. The display asks to “Wait a moment” while it is checking the zero point of the torque measurement
system.
September 2006
W41040300 V3.01
Page 32 of 67
5. Result of the zero check is shown in the display. Press ENTER to complete the zeroing procedure.
Write down the result.
6. Note: sensing element has to rotate freely. Anything touching the sensing element will interfere with
measurement
7. Reinstall the sensor according Chapter 3.5, Inserting the sensor.
6.3 Single-point calibration
Use the “Target Cs” procedure in the “Start-up” Menu to quickly start-up a new unit.
•
1. Go to “Target Cs” menu while KC/5 is measuring the consistency (Cs%) value of the process.
2. “Enter” the ‘presumed’ consistency of the process. KC/5 averages 30 seconds of measured torque
and adjusts calibration parameters S and Z to match the consistency value of the process. While
averaging, the display reads “Wait a moment”.
3. Take a sample while KC/5 is averaging and perform laboratory analysis to verify the ‘presumed’
consistency settings.
4. If lab consistency differs more than ±10 % from the ‘presumed’ consistency, go to “Edit Target Cs”
and change the original, ‘presumed’ consistency to the correct value and repeat tuning by selecting
“ENTER”.
5. Continue calibration fine-tuning by following steps described in Sections 6.5-6.6
6.4 .Zero adjustment
After initial calibration described in chapter 6.2-6.3 only zero adjustment (offset change) is usually needed.
This is done by changing Z value.
1. Take the sample.
2. Read the transmitter’s consistency reading when the sample is taken.
3. Make laboratory analysis.
4. Adjust Z to make lab and transmitter readings match.
Example:
KC/5 reading
Lab result
New Z = old Z + 0.3
3.2%
3.5%
If old Z = -7.0 New Z = -6.7
6.5 Sampling procedure
Laboratory samples are taken and stored in the KC/5 memory as follows:
1. Press “SAMPLE” button. The display indicates “Sampling Time Left in Seconds”. During a 30second countdown, the KC/5 averages 30 seconds worth of measurement value and stores that data
and the time of sampling, into the calibration data memory.
2. You must take the laboratory sample during this 30-second count down to match the stored
data.
3. The KC/5 display indicates: measured Cs %, the linearized measurement M, and the MIN-MAX
value. MIN - MAX value identifies the stability of the process during the sampling time. If the
consistency value is unstable during the sampling time, the sample extracted from the process will
not reflect the real consistency value – this sample is not a reliable basis to determine KC/5
calibration. Discard this sample. REPEAT the sampling process until a uniform sample is obtained.
The measured value is stored in memory by pressing “ENTER” or automatically after 5 minutes
have elapsed. By pressing “ESC” the sample value is discarded, and the display returns to the main
menu.
September 2006
W41040300 V3.01
Page 33 of 67
4. Analyze the sample in laboratory.
5. Enter the laboratory results into the KC/5 as follows:
•
a.
Select “Lab Values” from “Calibration” menu. The display indicates the time of the
last sample and the Cs average and the variation in the reading (“DIF”) during the time of sampling. Use the
“ENTER” button to scroll between “DIF”, “Lab Cs%”, or “M” values. When the value of “DIF” is > 1 % Cs, the
extracted sample should be rejected, and not used, by pressing “ESC”.
•
b.
Scroll with “↑” or “↓” buttons to reach appropriate sample data. “Time” provides
identification of the sample.
•
c.
Press “→” button to select desired data. Menu prompts “ENTER LAB VALUE”.
Enter by the “→” button, enter the laboratory value, then press “ENTER” to confirm the value or “ESC” to
discard it.
•
d.
When the sample data is not acceptable (for example, there is a large swing in
consistency during the sampling), go to “DELETE SAMPLE” mode and press “ENTER” to discard the
unacceptable sample values from KC/5 memory.
6.6 Changing calibration parameters
There are two possible ways of adjusting the calibration values:
1. Change Z and S manually.
2. Ask KC/5 to calculate a new Z and S based on stored calibration data.
6.6.1. Manual adjustment
Manual adjustment allows the operator to change the “Z” and “S” of the curve in use. This is performed in
the “Calibration” menu.
To achieve the highest degree of accuracy in calculating calibration parameters, KPM recommends use of a
spreadsheet-type program. Contact KPM for a copy of spreadsheet file compatible with Excel.
6.6.2. Transmitter calculated parameter change
When minimum of 3 laboratory samples have been collected and results entered into KC/5 memory, the
transmitter is ready to calculate “new” calibration parameters. Make certain that Cs varies ± 2% of set point
to ensure that the calculation is accurate. For a more accurate calibration, KPM recommends the use of
minimum five (5) sets of sample data.
1. Select “Calibration” menu. Use the “→” button to go to “Calibration calculation”.
2. The display shows “# SAMPLES OK ENTER CONTINUES”. The value # must be 3 (three) or higher
for the calculation to be performed. When fewer than three samples are entered, the display indicates
“Invalid Samples”. KPM recommends extracting minimum five (5) sets of sample data spread at ±
2% Cs to determine correct calibration information
3. Press “ENTER” to calculate new S and Z using the laboratory samples. The display shows the new
values, and the estimated error of calibration.
Please check that S is at realistic level, typically 1,5 -5.0. Limits to enter new value are 0.0 – 19.99. If
the result is unrealistic, discard and do not use the new parameters. Troubleshoot the calibration
data.
4. Press “ENTER” to accept the new calibration parameters or press “ESC” to retain the old values.
5. The program automatically returns to the Main menu.
Note! KC/5 requires a minimum of 3 laboratory samples to calculate calibration parameters. The
calibration data is stored in a stack of 10 data sets that follow the FIFO (First In First Out) principle.
When calculating calibration parameters, the KC/5 uses all data stored in memory at that time. The
“Estimated Calibration Error” indicates the reliability of the new data and helps determine the
validity of the calculated parameters. Therefore all unacceptable sample data must be deleted from
memory.

7. Maintenance
7.1 Regular maintenance of the KC/5
Safety Warning: Jack and Lock Ring must be secured and attached in place after re-inserting the
sensor, as per chapter 3.5.
The KC/5 requires no regularly scheduled maintenance other than checking that the seal water flow rate
stays between 0,5 – 2l/min (1/8 – ½ gal/min. When using the seal water reservoir, keep the water level
between 30%-70% full.
Seal water reservoir (optional, when mill seal water is not suitable)
The mechanical seal generates heat and requires cooling and lubrication. The seal water reservoir provides
water to protect he seal when mill seal water cannot be used.
Note: KPM recommends turning off the KC/5 motor during long process outages using “Process
Stop Output” (see Figure 4.1, Electrical connections, “DCS Connections”.
Check the seal water reservoir regularly – at least every other week, to determine the appropriate
replacement rate. The reservoir should be kept above 30% full. If fibres appear in the reservoir, drain
immediately and refill – fibres plug fluid channels and prevent seal fluid circulation. A large increase in fibre
quantity indicates that the front seal may need replacement.
Note! It is normal for mechanical seal to leak, but this should be kept at a minimum for longer seal
life. Seal water may become cloudy when fibres, fines or fillers mix with water.
7.2 Maintenance menu
The Maintenance Menu allows the user to perform two important functions:
•
To evaluate performance of the KC/5.

8. Reset to factory default values:
The user may reload the default values of S (Slope) and Z (Offset) for all pulp grades. Default values are
shown in Table 6.1. Other parameters that are returned to factory values are: sensing element type, output
filtering, and local grade selection mode. Grade names are changed to default in the selected language.
7.3 Motor controls
These functions are under the “Factory settings”-menu. Password 633 is required to enter.
1. Change of rotation speed:
The user may change RPM of the motor within 300-650 RPM. Display shows set speed, actual speed and
torque value. By pressing “Enter” the set value becomes permanent speed.
Measurement sensitivity and signal-to-noise ratio improves when RPM is increased. As a rule of thumb:
Cs range
Rotation speed
<3%
>3%
600 RPM
420 RPM
2. Change sensor rotation direction:
The user may change the direction of the motor rotation. Normal direction is ClockWise (CW) viewed from
the motor end of the sensor. Counter ClockWise direction is indicated as CCW.
Direction change is useful to remove wrapped material from sensing element. Reverse torque reading is
indicated only. This reading helps to determine if the sensing element has dislodged foreign materials.
Exiting the “Motor Controls” menu automatically returns the direction to CW).
3. Auto-reverse
The rotating direction of the sensor may be changed manually, or programmed to automatically reverse
after a pre-set interval.
The parameters are set in the form of A sec / B min / C:
September 2006
W41040300 V3.01
Page 37 of 67
A: selection of the time of reversed operation (default 10 sec). Time of reverse is adjustable from 1-120
seconds at 5-second intervals.
B: how often reversed operation occurs (default 3 min). The time is adjustable up to 180 minutes.
C: when auto-zero has been selected (set up menu) this number sets how much of the measured zero
point shift of the torque is corrected at a time. 0 means 100%, 1 means 0%. Default is 0.8 (= zero point
deviation is corrected in 20% steps).
NOTE: “Auto-Reverse” is interrupted, when:
•
The “Sample” button is activated.
•
Display unit is not showing the Main display window - KC/5 is operating. The interrupted “AutoReverse” function restarts one minute after returning to the required position.
The Output signal holds the last value displayed when “Auto-Reverse” is activated.
Use the “Auto-Reverse” mode in recycled pulp applications to remove foreign matter that may attach to the
sensing element. Reversing the rotation dislodges this material from the sensor. This helps reduce the need
to remove the sensor from the line to clean the sensor head.
7.4 Troubleshooting
The KC/5 features useful diagnostic functions to help find defective components. These easy-to-use
diagnostics are located in the “Maintenance / Check on-line signals” section. First, check the following:
1. Motor is running (RPM is as set).
2. Friction is less than 1 Nm. (FRICTION)
3. Motor voltage is 24 – 48 VDC (POWER)
If these values are not correct, use the wiring drawing (Figure 7-14) to help locate faulty component(s).
Check following voltages:
AC/DC Power supply outlet voltage is between 48±2 VDC. Measure at the AC Power Connection Board.
Motor Supply voltage is 24-48 VDC. Measure at Connection Board AND at the Sensor Board.
Sensor Supply Voltage is 12 VDC ± 1 VDC. Measure at Connection Board AND at the Sensor Board.
Problem
Potential source of problem & solution
A. Motor is not running
1. Check that the process stop binary input is not activated (if active
main display reads “Process stop”)
2. Check the power switch in display unit is ON
3. Check fuse in the display unit and reset if needed. (fig 7.14, 7.17 &
4.1)
4. Check that drive shaft is not jammed
•If jam is reason alarm message reads motor jam
•Check from on-line signals if motor tries to start (motor current)
•Rotate drive shaft from sensing element and try if it helps
•If not, replace mechanical seal or bearing assembly
5. Check power to the motor. See figure 7.14. (pins 9 & 10)
•If there is no power to the motor replace AC/DC power unit.
•If power ok change sensor board (See section. 7.13).
B. Erratically spinning
sensing element.
1. Sensing element needs to be re-aligned (See section 7.10). Or
damaged one changed
2. If gate valve has been closed while sensing element is inside it, the
moment shaft might also be bent. Check straightness of the head of
the moment shaft. Replace moment shaft if not straight.
C. Seal water reservoir

7.6 On-line Zero check
KC/5 measurement zero reading may be checked while the KC/5 is operating the following way.
1. Go to “Factory settings”, Motor Controls” menu and press”→” Read the mNm value and record it
when sensor is operating normally.
2. Change the direction of rotation to CCW by pressing “↓”
3. Read the CCW mNm value and record it
4. Change the direction of rotation back to CW by pressing “↓”
5. Repeat the test by reading and recording the CW mNm value again.
6. Change the direction of rotation to CCW by pressing “↓”
7. Read the CCW mNm value again and record it.
8. The absolute value of the average CW torque readings and absolute value of the average CCW
torque readings should be closely on the same level indicating the zero point of torque measurement
has not drifted.
9. If absolute values differ more than 2 mNm, adjust Torque offset according to section 6.2.
10. Exiting the “Motor Controls” menu automatically returns the direction to CW
Note! When process had quick consistency changes, the zero check may give faulty results due to
rapidly changing torque measurement. In Medium consistency applications, changes in torque are
typically so big and fast, the on-line zero check does not give good results. In MC applications,
check the zero according to section 7.8. Checking the functionality of the KC/5.
7.7 On-line sensitivity check
KC/5 sensitivity may be checked with a Torque Brake while the KC/5 is operating. The Torque Brake is

Connect the Torque Brake to the socket - this may be done without stopping the motor.
Hold the Torque Break firmly (not with excessive power) against the socket while avoiding contact
between shaft and case
Read the “T” mNm -reading from ”maintenance” menu, “on-line signals”
The T value mNm -reading should increase about the same than the brake set value from the nobrake level. If not, proceed as per section 7.7.
Reinstall the ”Check Torque” cap tightly

7.8 Checking the functionality of the KC/5 by removing the sensor from
the process
Remove the sensor from the process (see section 7.5)
1. Check the elastic protective shield and clean the front end of the probe
2. Place the KC/5 sensor unit into the horizontal position so the sensing element is free to rotate.
3. Connect seal water to the sensor
4. Connect the interconnect cable to the Sensor.
5. In the display unit, switch the power to the “On” position. The sensing element will rotate ClockWise –
CW – when looking from the Motor end of the KC/5.
6. The sensor is properly calibrated when “No-Torque T”-reading (the sensing element rotating in air) is
+/-2 mNm. T-value can be read from Maintenance/On-line Signals menu or from Calibration/Start
up/Torque Offset menu.
7. Clean the front part of the sensor and check to verify that, behind the sensing element, the elastic
shield is intact (see Section 7.10).
8. If the performance has not improved, then perform torque sensitivity calibration (see Section 7.9
below)
7.9 Torque sensitivity calibration
Torque calibration is performed by applying a measured torque force to the sensing element. The KC/5 is
factory calibrated using 0-85mNm. Low torque value, 0 mNm, is measured while the sensing element is
spinning in air.
1. Place sensor unit on the workbench with the display unit next to it.
2. Position the KC/5 so that the drive shaft is horizontal.
3. Connect seal water to the sensor
Note! When the KC/5 transmitter is operated in air, the mechanical seal will heat up if seal water is
not connected. This can damage the seal. To prevent this, make sure there is seal water in the
reservoir, or connect mill water to the seal water connections on the sensor.
4. Switch power ON in the display unit.
5. Select “torque setup” in maintenance menu and type in the high torque value to be used.
Press “ENTER” and place torque brake to the torque socket (See figure 7-2). Press “ENTER” to
initiate the calibration. After a while calibration raw value appears in display. “ENTER” accepts
the new number, “ESC” cancels.
6. Repeat above with low torque value (sensing element rotating freely in air).
7.10 Cleaning the sensing element
7.10.1. Cleaning debris wrapped around the sensing element using “Auto Reverse
Occasionally, debris catches on the sensing element – plastic, wire, string, etc. – and may even wrap
around the sensing element. This results in distortion of the measurement. Reversing the direction of the
rotation aids in removing the debris and foreign material.
1. Go to “Motor Controls” under “Factory Settings”. Select “Motor Direction” block, display
reads “CW” = clockwise. Select “CCW” = counter clockwise rotation direction.
2. Press ENTER and direction is reversed. Display returns to show RPM and T.
3. Allow the sensing element to run in reverse direction. Watch the “T” value decrease as debris is
released.
September 2006
W41040300 V3.01
Page 42 of 67
4. Return to normal rotation “CW”. Check the “T” value – if it still shows the original value, repeat
reversed rotation a few times until “T” reading indicates the removal of the foreign particles.
7.10.2. Cleaning the sensing element manually
The sensing element must be free to rotate with reference to the drive shaft. This twisting action is the
essence of the torque measurement. If hardened debris or chemical additives build up on elastic shield or in
the region between the sensing element and the shield, it can cause the sensing element to lock-up on to
the end of the shaft. This can cause a loss of sensitivity, and in the worst case, cause the output to be
frozen at a constant reading. To clean, proceed as follows:
1. Remove sensor from the process line (See section 7.5).
2. Remove the sensing element by unscrewing the fixing screw (See figure 7-3).
3. Remove shield locking ring, if necessary for cleaning
4. Clean and remove any build-up on the sensing element, elastic shield, and the area in between
them.
5. Check the condition of elastic shield; if cut or broken replace with a new one (See section 7.10)
6. Reattach the sensing element to the moment shaft and tighten the fixing screw.

7.12 Replacement of the mechanical seals
The KC/5 features tandem mechanical seals. The seal water is introduced between the front (process side)
and rear (motor side) seals. The front seal prevents pulp from getting inside the KC/5 probe housing. The
rear seal keeps seal water from getting to drive shaft bearings.
The seals are manufactured according to DIN 24960 standard and are available as stock items.
