3.1 Initial Inspection
Each Rolloscope is carefully inspected, both
mechanically and electrically before shipment. It
should be free from damage and in perfect operating
order upon receipt.
To confirm this, the system should be inspected for
physical damage incurred in transit. If damage is
found, contact the carrier and the distributor for
instructions. Retain the packing material.
3.2 Unpacking
Most of the domestic shipments are made by Van
Lines. The Rolloscope in this case does not need to be
crated, but is wrapped in plastic for protection.
Carefully unpack the Rolloscope and verify that all
standard and optional items according to Figure 3-2
are present.
The unpacking should take place only after a dust-free
location, where the Rolloscope will be used, has been
reserved and prepared.

3.6 Functional Checks
Providing that previous steps have been completed,
connect the Rolloscope to the power outlet then check
and verify that the Rolloscope is functioning properly.
See the Operation section of this manual and proceed
as follows:
a.
b.
c.
d.
e.
f.
g.
h.
i.
j.
k.
l.
Turn the Rolloscope on and verify that the green
light in the Main Switch comes on.
Drive the transport band from frame #1 to frame
#85. Check for smooth operation and that all film
holding strings are present.
Select several different frames and verify that the
transport band stops correctly.
While the transport band moves from one selected
number to another, press the STOP button and
make certain that the transport band stops at the
next frame.
Press NEXT UP and NEXT DOWN switches and
verify the function.
Press LAMPS ON/OFF switch and verify that the
lights in the light box turn on.
Turn the INTENSITY knob and verify that the light
intensity adjusts properly.
Operate one shutter at a time and verify that it
opens fully and closes down to about 3 inches (76
mm). It is possible that the shutters during
shipment have moved from their calibrated
positions and needs re-setting. In this case, go to
“Adjusting Shutter System”.
Store a different field in each of the PRESETS 1,
2, 3 and 4 and confirm that each of the fields can
be recalled at any time and in any frame.
Check that AUTO MODE ON and AUTO MODE
OFF are working correctly then leave it in AUTO
MODE ON. In AUTO MODE ON, the shutter
position in each frame number is automatically
memorized. For a description of AUTO MODE, see
“Shutter Control” in the Operation section of this
manual.
Set a small field and test the ROAM control,
horizontally, vertically and diagonally.
Check functions of optional foot switch (if included
in delivery).
Rev. F
Adjusting Shutter System
If the shutters, during the previous test, do not open or
close correctly, it will be necessary to do a reset
procedure as follows:
a.
b.
c.
d.
Press and hold Preset Switches 1 and 4 (see
Figure 4-3-5) until the light in both switches flash
once. This loads an artificial number into the
electronic positioning system, enabling shutter
movement in both directions.
Move the shutters out with the individual controls
but make certain to release the shutter control
switch as soon as the shutter reach its fully open
position.
Repeat this procedure if necessary until all four
shutters are returned to their fully open position.
Driving the shutters against the stops will produce
a rattling sound (cogging). Note that this will not
cause any damage if done briefly.
Press and hold Preset Switches 2 and 3 until the
light in both switches flashes once. This sets the
electronic positioning counters to zero. The
shutters are now calibrated.

4.1 Operating Principle
The operating principle for the Rolloscope is illustrated
in Figure 4-1. The following is a description of the
components:
1.
2.
5.
Shutter
After the films have been loaded to the frame in
the viewing area, the shutters are set to cover the
area not occupied by the films. There are four
independent shutters, two vertical (upper and
lower) and two horizontal. Only the vertical
shutters are shown in Figure 4-1.
6.
Diffuser
The acrylic diffuser in the front part of the light box
makes the light distribution even across the
viewing area.
7.
Transport Band
The transport band with film holding clips, see
enlargement in Figure 4-1, is used for holding and
transporting the films to the viewing area and onto
the take-up reels.
8.
Shutter Shield
The shutter shield is a clear acrylic sheet placed
between the shutter and the transport band. It
protects the shutter and also provides a solid
support when loading the films to the transport
band.
Lower Transport Band Take-Up Reel
When the first frame is selected for viewing, the
rest of the film transport band with all films loaded
are wound up on this take-up reel.
Upper Transport Band Take-Up Reel
For each higher frame selected, the film transport
band moves up and winds onto the upper take-up
reel. When viewing the last frame, all previous
frames are now stored on this take-up reel.
3.
Light Box
Multiple fluorescent lamps, providing a high
intensity of light, are placed inside the light box.
4.
Elastic Bands
When the films are moved out of the viewing area,
elastic bands are placed in front of them. This will
protect and hold the films in place as they are
moving into the take-up reels.

4.4 Loading and Unloading Film
1.
Loading Film
In Mammo mode the film holder is in the center of
the viewing area. This allows two rows of film to be
loaded. The upper row is loaded by inserting the
lower edge of the film under the upper edge of the
film holder. The lower row is loaded by inserting
the upper edge of the film under the lower edge of
the film holder.
Mammo films in the upper row and full size films
should be tucked under the holding string for
additional security.
Important Note: Films must not be placed outside
the right or left edges of the film holder. Doing so
may cause them to interfere with the photo sensors
operating along the edges of the transport band.
In Full Size mode the film holder is at the top of the
viewing area. This allows one row of film to be
loaded by inserting the upper edge of the film
under the lower edge of the film holder.
Films are best inserted by starting with a corner. A
corner is first secured under the film holder and the
reminder of the edge is inserted by rotating the film
around the corner pivot point. This is illustrated in
Figure 4-3-6.
Step 1:
Insert film corner under clip.
Step 2:
Rotate film around captive corner
while pushing up.
Figure 4-3-6. Film Loading

Unloading Film
Films can be removed by simply pulling them out
from the film holder.

Manual No. 131-500
5.1 Introduction
The Rolloscope is designed to require minimum
service and maintenance. Major mechanical
components of the Rolloscope are designed for long
life expectancy. In addition, the electronic controls
incorporate integrated circuits which are very reliable.
Service is therefore mostly limited to replacement of
such items as fluorescent lamps and items subject to
wear and tear.
WARNING
Read and follow the steps in the
Safety Information section of this
manual.
WARNING
Service and calibration of the
Rolloscope should only be performed
by qualified personnel.
Before a component is replaced, always make certain
that the malfunction of it is not caused by improper
calibration. For calibration procedures, see the
maintenance section of this manual. For available
parts and their location in the unit, see the parts
section of this manual.
WARNING
Disconnect the power cord before
removing any of the covers.
Should it be necessary to operate the
unit with the covers off, exercise
extreme caution, staying clear of
moving chains and live electrical
circuits.
5.2 Preparing for Service
To gain access to some of the components to be
serviced it is necessary to work through two cutout
openings toward the end of the transport band and/or
remove the covers. The procedures are outlined in
5.2.1 and 5.2.2.
The procedure in 5.2.1 requires the use of the optional
Transport Band Foot Switch shown in Figure 5-2-a. If
not available, please order:

5.13 Servicing Transport Band Drive
Principle of Operation
For keeping track of the frame count and stopping the
Transport Band (7) at the correct position, two Photo
Sensors (8 and 10) are used. The Photo Sensors are
activated by black labels placed along the sides of the
Transport Band. In normal (mammography) mode the
left sensor is used for frame counting and the right side
sensor for stopping point. In full frame mode the
functions are reversed.
Figure 5-13 shows the principle of operation of the
transport band drive. Following is a short description of
the operation:
When the operator selects a frame or activates the up
or down switches on the Frame Selector (1), a signal
goes to the Relay Interface Board (2). From there the
signal goes to the Motor Drive Board (3) which
provides power to the DC Motor (4).
As an added security, to make certain the band will not
go past its end position, two Magnetic Sensors (9 and
11) are used. The Magnetic Sensors will be activated
only if the Photo Sensors fail.
The DC Motor (4) drives the Transport Band (7) in the
direction determined by selection made on the Frame
Selector (1) and continues until the desired frame has
been reached.
To maintain a constant speed for Transport Band (7) a
Sprocket Gear is driven by the Band and a Gear Tooth
Sensor(5) monitors the speed by reading each tooth on
the sprocket wheel. This signal is then sent to a
Frequency/Voltage Converter(6). The DC voltage from
the converter is sent back to the Relay Interface Board
(2) which adjusts the speed of the DC Motor (4).

shows “0" or “86" even though the band is
not at the end position.
Films placed too close to the edge of the transport band. This will
disturb the photo sensors.
Transport band slows down when reaching
the selected frame but does not stop.
Instead, it continues at low speed until
power is turned off.
Stop point photo sensor not operating. Check stop point photo
sensor (right side sensor in normal mammo mode) by blocking
the beam. The red LED on the sensor should go off and the
output (black wire) should go from 24 V to 0 V. If it does not,
replace the sensor (section 5.13.4).
Transport band overshoots the stopping
point by several inches (stopping point of
band too high going up, too low going
down).
The switch “Service Speed High/Low” on the relay interface board
has inadvertently been left in position “High”. Return the switch to
its normal “Low” position.
Transport band will not move in either
direction. Frame selector is frozen on one
number and it appear to be flashing slowly.
Severe electrical or static noise has corrupted CPU memory
beyond watchdog reset capability. Perform “Super Reset” as
follows:
Turn power off. Hold RESET button on the frame selector down
(see the operating section of this manual) while turning main
power on. This will clear the memory and the FRAME NO. display
will flash “0". Dial in the number of the frame presently in view.
Press and hold the RESET button until the display stops flashing

5.14 Servicing Shutter Drive
Principle of Operation
Figures 5-14-a and 5-14-b show the principle of
operation of the shutter drive. Following is a short
description of the operation:
The signal goes from the Shutter Control (1) to the
Shutter Control Board (2) which directs the information
to the appropriate Step Motor Driver (3, 4, 5 or 6) and
on to the Step Motors.
Each of the four shutters is controlled by a Step Motor
M2, M3, M4 and M5 (see Figure 5-14-b).
A micro processor and a battery powered memory on
the Shutter Control Board (2) keeps track of the shutter
positions for the preset and for each frame.

Trouble Shooting the Shutter Drive
When trouble shooting the shutter drive, carefully
observe and record what is happening. First look for
the most likely causes as the ones listed below. If this
does not solve the problem, check the calibrations and
adjustments as outlined in the Maintenance and
Calibration Section of this manual.
SYMPTOM
Shutters do not open completely
WARNING
Disconnect the power cord
before removing any of the covers.
Should it be necessary to operate the unit with the
covers off, exercise extreme caution, staying clear of
moving chains and live electrical circuits.
CHECK/ADJUST
Reset shutter position as follows:
a.
b.
c.
d.
Press and hold Preset Switches 1 and 4 (see Figure 4-3-5)
until the light in both switches flash ones. This loads an
artificial number into the electronic positioning system,
enabling shutter movement in both directions.
Move the shutters out with the individual controls but make
certain to release the shutter control switch as soon as the
shutter reach its fully open position.
Repeat this procedure if necessary until all four shutters are
returned to their fully open position. Driving the shutters
against the stops will produce a rattling sound (cogging).
Note that this will not cause any damage if done briefly.
Press and hold Preset Switches 2 and 3 until the light in both
switches flashes ones. This sets the electronic positioning
counters to zero. The shutters are now calibrated.
Note: Should the symptom recur, check for malfunctioning step
motor driver.
One of the shutters moves in one direction
only, regardless of toggle switch direction
input.
Step motor driver defective. (Direction input not responding).
Replace driver.
One of the shutters moves unevenly and
loses position, requiring frequent shutter
resets.
One of the step motor drivers is defective. Run one shutter only at
a time to determine which shutter is causing the problem.
Replace the step motor driver for that shutter.
One of the shutter motors is making a
humming or high-pitch noise even when
not activated.
Step motor driver defective (switching oscillator frequency off).
Replace step motor driver.

5.14.1 Replacing PC Boards for Shutter Drive
Three types of PC Boards, as shown in Figure 5-14-a,
are directly involved in the shutter drive. They are, the
Shutter Switch Board, located in the Shutter Control
(1), the Shutter Control Board (2) and the Step Motor
Driver Boards (3-6). The Power Supply Board (see
Figure 5-3-1) is also involved as it provides power for
the transport band drive.
To replace the boards, follow the directions in sections
5.8 and 5.9.
Note: If any of the Step Motor Driver Boards are
replaced, the DIP switches on the board should be set
as shown in Figure 5-14-c.
After board replacement, check and calibrate
according to instructions in the Maintenance and
Calibration section of this manual.

5.14.2 Replacing Step Motors
The four step motors, M2, M3, M4 and M5 are mounted
to brackets attached to each corner of the light box.
See Figure 5-14-b.
The step motors are very reliable and would not be
expected to require replacement. If, however,
replacement is needed, see Figures 5-14-b and 5-14-c
and proceed as follows:
a.
b.
c.
d.
e.
f.
g.
h.
Make certain power is off and the line cord
disconnected.
Remove right, left, back, top front and top covers
as described in section 5.2.2.
position the cutouts in the transport band in the
back of the light box.
Turn power off.
Make a sketch and mark the wires connected to
the step motor to be replaced.
Disconnect the wires from the terminal board.
Remove the four screws with nut and washer,
holding the motor to the bracket.
Lift the timing belt off the pulley and pull the motor
out and away from the bracket.
i.
Note the clearance between the pulley and the
motor body. Use a 5/64" hex wrench and transfer
the pulley to the new motor with the same
clearance between the pulley and the motor body.
j. Install the new motor in reverse order. Before
tighten the nuts, move the motor back and fort
until the timing belt has the proper tension.
Applying a slight pressure to the belt between the
two pulleys should cause a deflection of
approximately 1/4". Also, check against other
motor/timing belts
k. Make certain that the shutter controlled by the
motor replaced is in its fully open position. If not,
turn the motor pulley manually.
l. Restore normal operation by completing the steps
in section 5.2.1.
m. Press and hold Preset Switches 2 and 3 (see
Figure 4-3-5) until the light in both switches starts
to flash.
n. Check that the shutter open and closes
completely. If needed, follow the check/adjust
procedure in the Trouble Shooting section 5.14.

7.2 Transport Band Cleaning
Cleaning by User
Cleaning by Qualified Service Engineer Only
The front surface of the transport band is easily
cleaned from the front of the Rolloscope. A high quality
plastic cleaner, such as “Kleenmaster* Brillianize”,
compatible with polyester resin can be used.
The back of the transport band is not exposed, so it
should normally not need cleaning. In case, however,
it would need cleaning in certain areas, it must be done
from the inside of the Rolloscope. Proceed as follows:
* Kleenmaster is a registered trademark of
The Brillianize Company, Benicia, CA 94510.

f.
Remove side and back covers according to
instructions in section 5.2.2.
Drive transport band so the area to be cleaned is
behind the back of the light box.
Turn power off.
Clean the back of the transport band by reaching
in from each side in the opening above the upper
take-up reel.
Turn power on and go to the next area needed
cleaning.
Repeat c, d and e as needed.
7.3 Viewing Area Cleaning
The viewing area behind the transport band (the front
of the shutter shield) may be cleaned from the front of
the Rolloscope. The same kind of cleaner used for the
transport band should be used.
Use the cutouts at the end of the transport band (past
frame #85) to access the surface of the shutter shield.
Proceed as follows:

7.4 Check Decals and Operator Safety Instructions
Verify that all decals and labels with safety instructions
are in place.
7.5 Check Resistance from Cabinet to Input Power Connector Pin
With a Digital Multimeter, check that the resistance
from any exposed metal point of the cabinet to the
power connector ground pin is less than 0.10 ohm.
Make certain to check the resistance of the test leads
(normally between 0.10 and 0.20 ohm) and subtract
this from the reading obtained during the resistance
check.
7.6 Voltage Measurements
Voltage measurements are made on three circuit
boards, the Power Supply Board (PSB), the Shutter
Control Board (SCB) and the Frame Selector Board
(FSB). See tables and figures 7-6-a, 7-6-b and 7-6-c.
Note:
If voltage readings are not in the range of the
reference, the first step is to check that the
line voltage is connected to the correct taps
on transformer T1. See section 3 “Installation.”
To gain access to the Power Supply Board and the
Shutter Control Board, see section 5.3. For the Frame
Selector Board, see section 5.9.

Mark on the masking tape the exact position of the
film holder after a stop.
Continue to mark the stopping point, going from 0
to 85 and back, using both single stepping and the
frame selector.
The variation in the stopping point should not
exceed 1/4" (6 mm).
If variation in the stopping point exceeds 1/4" (6mm),

Adjustments on Motor Drive Board
Remove the Cover for Electronics and the Right Side
Cover as directed in Section 5.2.2. See Figure 5-3-1
and locate the Motor Drive Board.
The Motor Drive Board is shown in Figure 7-7-b. There
are four trim potentiometers on the board. They are all
adjusted at the factory and should normally not have to
be readjusted in the field.
If the board is replaced, the trim potentiometers on the
new board should be set to the same value as on the
old board unless instructions sent with the new board
from the Rolloscope manufacturer gives different
directions.
To identify the trim potentiometers settings, we use a
twelve hour clock.
The factory settings for the trim potentiometers are as
follows:

about 9.7 VDC. Note that turning the trim pot CCW
increases the voltage.
Drive the transport band in the down direction from
85 to 80 several times and note the highest
reading. It should be between 9.5 and 9.9 VDC.
Using the frame selector, run the transport band
from 0 to 85 and measure the time from start to
stop. The time should be 2 min. 32-34 sec. Repeat
the procedure from 85 to 0. The time should be the
same. If necessary, make small adjustments on
the HIGH SPEED potentiometer to bring the time
in the range specified.

Choose a frame about 10 frames from the end of
the band (for example 10 or 75) and approach it
from both directions using NEXT UP and NEXT
DOWN switches.
If the two stopping points are overlapping, reduce
the setting of the LOW SPEED potentiometer R6
on the Relay Interface Board shown in Figure
7.7.c.
If the stopping points are apart from each other,
increase the setting of the LOW SPEED
potentiometer R6.

Use the foot switch and drive the band up past
frame 85 until the steel shims are close to the
magnetic sensor on the right side.
Continue to drive the band up and make certain
that the magnetic sensor is activated by the steel
shims and that the band stops.
With the foot switch, drive the transport band down
a couple of feet.
Drive the transport band up again and make
certain that the magnetic sensor is activated and
the band will stop.
Repeat steps d and e several times. If the
magnetic sensor fails to stop the band at any time,
go to “Adjusting Magnetic Sensor.”

Turn power on.
Use the foot switch and drive the transport band
down and past frame 0 until the steel shims are
close to the magnetic sensor on the left side.
Continue to drive the band down and make certain
that the magnetic sensor is activated by the steel
shims and that the band stops.
With the foot switch, drive the transport band up a
couple of feet.
Drive the transport band down again and make
certain that the magnetic sensor is activated and
the bend will stop.
Repeat steps d and e several times. If the
magnetic sensor fails to stop the band at any time,
go to “Adjusting Magnetic Sensor.”
See Figure 5-2-f and set S1 to LOW speed and S2
to NORMAL MODE.
d.
Follow steps a - d in the checking procedure and
stop the band when the steel shims are below the
magnetic sensor.
Turn power off.
See Figure 7-8-a and check that the AIR GAP is
about 0.1 inches (2.5 mm). If the AIR GAP is more
than 0.1 inches, bend the bracket gently and
recheck the AIR GAP.
Also, check that all three steel shims are in the
correct place and properly secured to the transport
band.
If, after making proper adjustment, the magnetic
sensor still is not stopping the transport band, check
the sensor itself and the associated circuits. The
sensor is a normally open Reed Switch and can be
checked by an ohm meter. W ith power turned off,
connect the ohm meter to the sensors leads and place
a steel object directly on the surface facing the
transport band. The contact should now be closed.

7.9 Check and Adjust Photo Sensors
WARNING
During this test it is necessary to
operate the Rolloscope with the
covers off. Exercise extreme caution,
staying clear of moving chains and
live electrical circuits.
There are two photo sensors used to keep track of the
frame count and to stop the transport band in the
correct position. The location of the photo sensors is
shown in Figure 5-13-a.
a.
b.
c.
d.
e.
Each photo sensor consists of two parts, the emitter
and the receiver. The transport band is passing
between the emitter and the receiver where black
labels along the edge of the band will interrupt the
photo sensor beam, sending a signal to the Rolloscope
control.
See section 5.2.2 and remove Left Side Cover,
Right Side Cover and both Back Covers.
Drive the band from 0 to 85 and confirm that all
black labels are in place.
Stop at several places and confirm that the center
of the photo sensor beam is aligned with the
center of the black label as shown in Figure 7-9-a.
The position of the photo sensors has been
adjusted at the factory and should not have to be
changed.
If there are problems with alignment from one end
of the band to the other (band “walking” from side
to side), it is most likely caused by a misalignment
of the band itself. The adjustment for this is rather
complicated and involves not only the take-up
reels and supporting rollers, but also the elastic
bands. Should this adjustment be required, consult
with a factory representative.
It is important that the band with its labels is correctly
aligned with the beam of the photo sensor. This is
shown in Figure 7-9-a. To check this, proceed as
follows:

7.10 Check Frame Selector
To check the operation of the frame selector, see the
operating section in this manual and proceed as
follows:
e.
f.
a.
b.
c.
d.
Select Mammo Mode.
Select at least 20 different frame numbers at
random. Check for correct movement and that the
frame number corresponds to the display.
Select every five frames (5, 10, 15...) Up to 85 and
back to 0. Check for correct function.
Press STOP while the transport band is moving.
Check that it stops normally and retains correct
frame number.
g.
W ith the transport band running, load a new
number. Check that it goes to the new number and
retains the correct frame number.
Test the function of NEXT UP and NEXT DOWN
switches at least 20 times, both single stepping
and by holding them down. Check that it stops
normally and retains correct frame number.
Single step through all positions (0 to 85) and
check stopping position in each frame. Repeat
procedure from 85 to 0. Check that the stopping
point variation is less than 1/4".
7.11 Check and Adjust Shutter System
Checking Shutter System
Adjusting Shutter System
See OPERATION section of this manual and check the
following:
If the shutters, during the previous test, do not open or
close correctly, it will be necessary to do a reset
procedure as follows:
a.
b.
c.
d.
e.
f.
Operate one shutter at a time and verify that it
opens fully and closes down to about 3 inches. Do
several instant reversals and verify there is no
“Cogging” (rattling sound accompanied by shift in
zero position).
Store a different field in each of the PRESETS 1,
2, 3 and 4 and confirm that each of the fields can
be recalled at any time and in any frame.
Check if the shutters are in AUTO MODE ON or
AUTO MODE OFF. In AUTO MODE ON, the
shutter position in each frame number is
automatically memorized. For a description of
AUTO MODE, see “Shutter Control” in the
Operation section of this manual.
Set AUTO MODE ON. Verify proper function by
setting all four shutters to any position (except
fully open). Move to the next frame and check that
the shutters change position. Return to the
previous frame and verify that the shutters return
to the position you had set.
If found in AUTO MODE OFF, make certain the
customer wants it in this mode, before changing it.
Set a small field and test the ROAM control,
horizontally, vertically and diagonally.
Rev. F
a.
b.
c.
d.
Press and hold Preset Switches 1 and 4 (see
Figure 4-3-5) until the light in both switches flash
ones. This loads an artificial number into the
electronic positioning system, enabling shutter
movement in both directions.
Move the shutters out with the individual controls
but make certain to release the shutter control
switch as soon as the shutter reach its fully open
position.
Repeat this procedure if necessary until all four
shutters are returned to their fully open position.
Driving the shutters against the stops will produce
a rattling sound (cogging). Note that this will not
cause any damage if done briefly.
Press and hold Preset Switches 2 and 3 until the
light in both switches flashes ones. This sets the
electronic positioning counters to zero. The
shutters are now calibrated.
Note: Should the symptom recur, check for a
malfunctioning step motor drive or misadjustment
causing excessive friction in the shutter movement.
