Notes on safety • • • • • • • • Emergency off: Press the yellow/red main switch on the temperature control unit (when present) or pull out the plug. Thermal oil is combustible under certain conditions, therefore: – Do not place the unit in the vicinity of heat sources (e.g. oven in die-casting plants). – Keep thermal insulation clean at all times. Insulation soaked in thermal oil is a fire hazard. – Repair leaks in the temperature control circuit (unit, connection lines, consumer, etc.) immediately. Burning thermal oil can be extinguished with: – AFFF spray foam fire extinguisher. – Powder fire extinguisher (avoid using near dust-sensitive equipment, e.g. process controllers, computers, etc.) – CO2 fire extinguisher (Backflash hazard, suitable only under certain conditions). The suitable fire extinguisher shall be provided by the operator under consideration of the equipment found in the room and all applicable safety regulations. Never operate the unit without the side panels in place. Protect the unit from sprays and cleansers containing solvents. Injury hazard from leaking hot thermal oil. – Before detaching connecting hoses in the temperature control circuit, cool the unit down and then switch it off, depending on the magnitude of the outlet temperature. – Check if the pump has stopped. In equipment in which a malfunction of the temperature control system can be hazardous to operating personnel or lead to destruction of the equipment, independent monitoring equipment to monitor the process and switch the equipment off safely. The unit shall not be placed in areas subject to explosion. BA 150S-350L/0703/d/f/e 27 • These Operating Instructions belong in the hands of the set-up and operating personnel. Please ensure that the Operating Instructions are read. You will thereby save yourself unnecessary costs and problems during the set-up as well as prevent downtime. 2. Range of application The temperature control unit serves to heat or cool injection moulds and diecasting dies, extruders, calenders, mixers and other consumers in areas not subject to explosion. The units are designed for use with thermal oil up to the following maximum outlet temperatures: Model 150S: 150 °C (special version to 180 °C), Model 300S, 300(DG), 301(DG): 300 °C. Model 350L: 350 °C. For technical data, see Section 12. 3. Set-up 3.1 Unpacking Do not tip the unit. The heat transfer fluid remaining from the test run could run out, which could soak the insulation. 3.2 Placing the unit The unit is designed for an ambient temperature of 10 to 40 °C. When placing the unit, ensure that there is sufficient ventilation. The distance between units or between a unit and the wall must be at least 4 cm Place the unit on a level base and engage the wheel brakes. The unit shall not be placed in the vicinity of heat sources, e.g. ovens in diecasting plants, as thermal oil is combustible under certain conditions. 3.3 Consumer checks Before connecting the hoses between the consumer and the temperature control unit, the following checks shall be performed on the consumer: 1 Check conduits for blockage. 2 Remove fluid and dirt residue using compressed air. Foreign bodies such as splinters can damage the pump. 3 Remove rust, scaling and oil residue, as these strongly restrict heat transfer between the consumer and the heat transfer fluid and increase the pressure drop in the consumer. The Regloplas descaling unit, REG, can be used to descale (→”Regloplas Temperature Control Units” brochure, “REG” Data sheet). The Regloplas System Cleaner, SR80, can be used to remove oil deposits (→ ”Regloplas Temperature Control Units” brochure, “SR80” Data sheet). 4 When switching between water or steam to thermal oil, all water residue in the consumer and in the connection hoses must be removed completely: Accident hazard during heat-up due to the pressure of the steam thus created. Proceed as described in Section 7.3. 3.4 Water quality To prevent damage to the temperature control unit cooler, the water used must meet the following requirements: Total hardness 4–18 °d Ph value 7–9 KKG* Conductance max.1000 µS/cm *KKG = Lime/carbon dioxide balance 3.5 Connection hoses See also page 39. – Outlet and inlet: Use only pressure and temperature resistant hoses (→ ”Accessories for temperature control units” brochure). For pipes, the thermal expansion must be taken into account. The connection hoses shall be laid out such that they are protected from accidental contact. 28 BA 150S-350L/0703/d/f/e – Cooling water inlet: The pressure must be at least 3 bar. Use only pressure-resistant hoses. (→ ”Accessories for Temperature Control Units” brochure). For the connection to the public mains, follow applicable guidelines and safety regulations (e.g. connecting the unit via a system separator). – Cooling water outlet: Must be free of backflow and always open. The hose shall be fastened such that any vapour escaping at the beginning of the cooling process do not present a hazard. Unsealed coolers can release thermal oil into the wastewater. – Overflow of the expansion vessel: Must always be open. For safety reasons, the cooler must always be connected. 3.6 Electrical connections 1 Mains voltage and frequency must match the information found on the rating plate. 2 Check the back-up fuse value according to the information in the electrical schematic in the electrical part of the unit. 3 All applicable guidelines and safety regulations shall be followed when connecting the unit to the mains. 4 Markings of the connection cable strands in accordance with IEC standards: 3P E yellow/green black-brown/blue 3.7 Filling the heat transfer fluid After checking the consumer, and connecting the hoses and electrical cables, proceed as follows: 1 Switch on the main switch on the unit (when present). 2 Open the vent and shutoff valves (when present). 3 Using a funnel, pour the thermal oil into the filling port slowly, until the level control’s red indicator lamp (when present) of the level control at the top of the unit to the rear near the filling port extinguishes. Minimum filling quantity in accordance with Section 12 of the Technical Data. Warning: Every time the unit is filled with thermal oil, the unit and the temperature control circuit must be vented as follows: Switch the unit on. To prevent overheating of the heating elements due to initial trapped air in the temperature control circuit, the outlet pressure in the unit is monitored by a minimum pressure switch. It will interrupt heating when the pressure is too low (0.7 bar) and the flow alarm will be activated. To prevent the heater from being switched on before the controller is switched on, a set-point value of approximately 10 °C is set and the unit is vented at this value for approximately 10 minutes. Recommended thermal oil: Regloplas RO150 (only for model 150S), RO300 or Therminol 66 (→ ”Accessories for temperature control units” brochure). As a preventative measure, we recommend the addition of the SR80 system cleaner (→ ”Regloplas temperature control units”, ”SR80” data sheet). 4 Do not close the vent valve at the consumer until thermal oil flows from it regularly. 5 As newly filled thermal oil usually contains moisture, the moisture must be removed as described in Section 7.3, Operations 4 and 5. BA 150S-350L/0703/d/f/e 29 4. Switching on 4.1 Switching on with the RT30 controller (Fig. 1, Table 1) 1 Switch the unit/pump on using the corresponding switch. After it is switched on, the RT30 runs a functional test for approximately 5 seconds. During this test, all displayed values will blink. Once the test has been successfully completed, the actual value will appear in the upper display and the set-point value in the lower. 2 Check the pump’s direction of rotation using the direction of rotation arrows. If the direction of rotation is incorrect, switch the two phases in the unit’s plug. Important: The rotary switch (when present) on the front plate must be in the ”+” position, i.e. pumping mode. 3 Continue filling the thermal oil only as long as the pump runs without interruption and the red display lamp of the level controller goes out, that is, sufficient thermal oil is circulating in the temperature control circuit (unit, connecting hoses, consumer, etc.). 4 Check the temperature control circuit (unit, connecting hoses, consumer, etc.) for leaks. 5 Close the vent valve only when water runs out of it regularly. Fig. 1: Controller RT30 Element Meaning Lamp lights MAIN AL 1 Pump, Control Heating Cooling Level control Motor contactor Safety thermostat –– In operation In operation Insufficient heat transfer fluid in circuit Thermal relay has released Temperature too high Table 1: Control and display elements with RT30 controller 4.1.1 Setting elements – Set the set-point value using the ”∆“ and “∇“ keys. – Neutral zone: This is set at the factory to +2 °C. Between the set-point value and the selected value of +2 °C, the unit will neither heat nor cool. 4.1.2 Malfunction indicator In the event of a sensor break, the message “Sbr” will be displayed. In the event of a sensor short circuit, the message “Err” will be displayed. In both cases, cooling is switched on, to ensure that the consumer is protected against overheating (display lamp “Al 1”). 4.2 Switching on with the RT50 control system (Fig. 2) 1 Once the main switch on the unit has been turned on, “OFF” will appear in the display. The RT50 is now ready for operation. 2 Switch on by pressing the “ON/OFF“ key. Depending on the programming, the set-point and actual values as well as information on the operational state of the control system and unit will appear on the display. 30 BA 150S-350L/0703/d/f/e 4.3 Operating and display elements (Fig. 2) 1 LCD display. 2 Keys for programming and selecting the display. 3 Alarm reset key. 4 On/Off key. 5 Key for leak-stop mode. 6 Key for suction and blow-out. 7 Key for switching between set-point values SP1 and SP2. 8 Key for operation with timer. 9 Keys for entering set-point value and programming. 10 Status line. 1 10 2 3 9 4 5 8 7 6 Fig. 2: Eléments de commande et d’affichage Set-point and actual value displays Once the control system has been switched on using the “ON/OFF“ key, the set-point temperature SP1 or SP2 (SP = Set-point) will appear in the lower part of the display, and in the upper part the actual value of the outlet temperature S1 of the internal sensor in the heat transfer fluid or S2, the temperature of the external sensor in the consumer (S = Sensor). Keys for entering the set-point value and programming Increasing or decreasing the set-point value, selecting the program position, changing the programmed values. Timer key If the RT50 is equipped with a timer, it is activated by this key. The unit is switched on and off via the timer. Leak-stop key Pressing this key puts the unit into leak-stop mode. Leak-stop mode is possible only when the set-point value is between 0 and 250 °C max. In leak-stop mode, the heating capacity is at a maximum of 60% to keep the thermal load on the oil due to the reduced pumping capacity low. The leak-stop function can be stopped by pressing the “ON/OFF“ key (wait until “OFF“ appears on the display). The unit will then switch over to normal mode. Suction key (evacuation). Pressing this key initiates the evacuation sequence. The consumer connected to the unit is evacuated by the pump. Evacuation is possible only when the temperature of the heat transfer fluid is below the value programmed for the run-out temperature “RT50 Operating Instructions“, Section 7.2, P 4.3). If this is not the case, the unit will first cool the heat transfer fluid to this value. The pump is switched off. Once the pump run-out time (“RT50 Operating Instructions“, Section 7.2, P 4.9), has elapsed the pump is switched on again in the opposite direction of rotation. The pump then evacuates the consumer during the programmed evacuation time (“RT50 Operating Instructions“, Section 7.2, P, P 4.6). After the programmed evacuation time, the unit switches off automatically. The suction process can be interrupted by pressing the “ON/OFF“ key. Pressing the “ON/OFF“ key again. Alarm Reset key Function: – Manual reset of the alarm relay (e.g. switching off a horn). Once the malfunction has been corrected, the alarm display can be erased by pressing the key once more. – Manual acknowledgment of the automatic switch from control of the consumer temperature or cascade control to control of the outlet temperature in the event of a defective or missing S2 sensor in the consumer. SP key Switchover between set-point value 1 (SP1) and set-point value 2 (SP2). Note: Set-point value switchover is possible only when no alarm is active. Operation with code To prevent the set/programmed values from being inadvertently changed, we strongly recommend the use of a code. There are 4 possibilities: – Entered value code BA 150S-350L/0703/d/f/e 31 – Set-point value code – User setting 1 code – User setting 2 code Programming these codes is described in the “RT50 Operating Instructions”, Section 7.2, item 15. Save/Reset to Factory or user setting The RT50 control system offers the possibility to reload the factory settings easily and at any time. In the same way, two different, customer-specific settings can be reloaded (user settings 1 and 2). Programming these codes is described in the “RT50 Operating Instructions”, Section 7.2, item 14. 5. Switching off 5.1 Switching off with the RT30 controller 1 Cool the unit and the temperature control circuit to 80 °C or below. 2 Switch off the pump using the switch (→ Table 1). 5.2 Switching off with the RT50 control system 5.2.1 Using the On/Off key The switching off process is initiated by pressing the “ON/OFF” key or via the timer. The switching off process runs automatically depending upon the temperature of the heat transfer fluid as follows: – Pump and control are switched off. The RT50 is still under power (stand-by mode). The display indicates “OFF”. 5.2.2 By previous evacuation of the consumer See Optional equipment, Section 10. 6. Changing the consumer. Shutting the unit down for more than one month. Switching the unit back on Before removing connection hoses, ensure that the unit is switched off and that all circuits are free of pressure. The unit must be evacuated completely and stored in a dry location between 10 und 40 °C when not used. Depending on the storage location, condensed water can develop, so the procedure described in Section 7.3, 2–5, must be performed. 7. Maintenance 7.1 Periodic checks and maintenance procedures To make the maintenance procedures easier, the RT50 control system is equipped with a service-interval display. We recommend entering the corresponding service interval (e.g. 2000 hours). For programming, see “RT50 Operating Instructions”, Section 3.9. We recommend that the following cleaning procedures are performed every time heat transfer fluid is added or replaced. Please note that the following information is for 8 hours of operation daily. For operations with more than one shift, these checks and maintenance procedures shall be performed in correspondingly shorter intervals. Defective components shall be repaired or replaced immediately. • Checks and maintenance procedures shall be performed by qualified personnel. • Maintenance procedures on the electrical equipment shall be performed by a qualified electrician. • Main plug shall not be pulled out until the unit is switched off. • When working with pumps with magnetic couplings, be aware of danger from magnetic fields: – People with pacemakers and/or implanted metal components must maintain sufficient distance from the unit or should not perform maintenance operations on the pump. – When pushing the magnetic coupling together, hold the motor such that no fingers could be trapped as a result of magnetic strength. – Maintain the necessary distance from computers, diskettes, credit cards, electrical watches, etc. 32 BA 150S-350L/0703/d/f/e 7.1.1 Daily checks/maintenance Check the temperature control circuit (unit, connecting hoses, consumer, etc.) for leaks. Fix any leaks immediately. Replace oily insulation immediately and remove any oil spills. 7.1.2 Monthly checks/maintenance 1 Check the inlet opening for the pump cooling for blockage. Clean unit from the inside to the outside using compressed air. 7.1.3 Semi-annual checks and maintenance 1 Remove level switch and clean (→ Service). 2 Check the function of the safety thermostat. Attention: The temperature control circuit (unit, connecting hoses, consumer, etc.) must be suitable for the check temperature. Enter the set-point value at the controller as follows: Model 150S: 160 °C (Version to 180 °C: set value to 190 °C). Models 300S, 300(DG), Model 301(DG): 320 °C. Model 350L: 370 °C. Heat the unit (temperature control circuit) to this temperature. With the RT30 controller, the “Safety thermostat” lamp will light up. The heat must switch off. With the RT50 system, the outlet limit (“RT50 Operating Instructions”, Section 7.2, P 3.2) or maximum setpoint value (P 4.4) may need to be entered correspondingly. The alarm “Safety thermostat triggered” will appear on the display. The unit must now cool. Attention: After these checks have been completed, reset to the original set-point value. 3 Check the electrical equipment such as grounding wires, contactors, firm positioning of the connection cables, etc. 4 Check the oil after approximately 1000 hours of operation (corresponds to approximately half a year under 1 shift operation). The only way to tell if the oil can continue to be used is by analysing it, preferably performed by the heat transfer fluid manufacturer. The dark colour is not indicative of the condition of the oil. Approximately 1 litre of used oil is needed for the analysis. For safety reasons (escaping oil vapour is a fire hazard), the oil must be removed at a low temperature (approximately 30 °C). The sample should be marked with: address, date of removal, outlet temperature and type of heat transfer fluid. The analysis is generally provided by the manufacturer at the actual cost. 5 Dismantle the solenoid valve for the cooler in accordance with the drawing (→ Service): Check the membrane for scaling and damage. Ensure that the core and spring bolts move smoothly. Clean or replace components as necessary. 7.1.4 Annual checks/maintenance Always change the oil after approximately 2000 hours of operation (corresponds to about 1 year in 1 shift operation). This value is a guideline. Depending on operating conditions (temperature, narrow consumer cross-section, primarily heating, etc.), the oil may need to be changed more frequently (→ 7.2). 7.2 Changing the thermal fluid Change the thermal fluid as follows: 1 Evacuate the unit and consumer completely through their corresponding draining port. 2 Depending on the number of operating hours, clean the unit and consumer as described in Sections 7.3 and 7.4. 3 Refill as described in Section 3.7. 7.3 Switching the consumer from water to thermal oil Procedure when condensation forms 1 Check the consumer for scaling and clean with the REG descaling unit (→ ”Regloplas Temperature Control Units”, “REG” data sheet). 2 Attention: All water residues in the temperature control circuit (connection hoses, unit, consumer, etc.) must be removed completely. Any vapour pressure presents a hazard during the heat-up phase. Procedure: 3 Fill thermal oil as described in Section 3.7. 4 Allow the unit to run at a temperature of 100 °C for at least 30 minutes. BA 150S-350L/0703/d/f/e 33 5 When no more boiling sounds can be heard, increase the temperature to the desired operating temperature in 10 °C increments. If boiling sounds continue, allow the unit to run at the same temperature unit no more boiling sounds can be heard. The unit is now ready for operation with thermal oil. 7.4 Cleaning Please note when using solvents for cleaning: Due to danger of explosion, do not blow out the unit. It must be rinsed thoroughly. When using a solvent, the manufacturer’s regulations on usage must be followed. Thermal oil and solvents are combustible under certain conditions. Cleaning must not be performed in the vicinity of heat sources. We recommend that the following cleaning procedure be performed every time the heat transfer fluid is added or changed. Conditions which are less than optimal will require that these procedures be made with greater frequency. This is particularly true for points 5 and 6. 1 Evacuate the unit through the draining port. 2 Clean the filter in the temperature control circuit. 3 Check the cooler for scaling; clean with the REG descaling unit if necessary. 4 Remove and clean the heating elements if the oil was very dirty or if the manometer pressure was high. 6 Dismantle the solenoid valve for the cooler in accordance with the sketch (→ Service): Check the membrane for scaling and damage. Ensure that the core and spring bolts move smoothly. Clean or replace components as necessary. 8. Ordering spare parts Use only original spare parts. To ensure quick and accurate delivery of spare parts, we need the following information 1 Type of temperature control unit 2 Model number 3 Voltage 4 Frequency You will find this data on the unit’s rating plate. 5 Part number of the component. You will find this information on the corresponding drawing in these Operating Instructions (→ Service) as well as on the schematic in the electrical section of the unit. 9. Shipping Before shipping the unit, evacuate it completely through its draining port. Due to danger of freezing (collapse if the cooling hoses), blow the cooler out at a low temperature as follows: 1 Enter a set-point value of 0 °C at the controller. 2 Ensure that the cooler’s solenoid valve is open. 3 Blow out the cooler with compressed air at a maximum pressure of 6 bar. Do not tip the unit. Heat transfer fluid remaining in the unit could run out, presenting the danger of saturate the insulation, the electrical components and thus danger of fire. Use the original packing material. Mark the “Top” clearly. 10. Optional equipment 10.1 Leak-stop mode and evacuation of the consumer through suction By reversing the pump’s direction of rotation, the heat transfer fluid can be removed through the consumer by means of vacuum. 34 BA 150S-350L/0703/d/f/e To note – In leak-stop mode, the oil is subject to high thermal loading due to the greatly reduced pump capacity. For this reason, the oil must be checked and changed, if necessary, more frequently. For the procedure, see Section 7.1.3, item 4, and Section 7.1.4. – When suctioning, the volume of heat transfer fluid must be less than the volume of the expansion vessel (see “Technical data”, Section 12). Otherwise, the unit will overflow. Leak-stop mode with the RT30 controller 1 Switch the unit off as described in Section 5.1. 2 Set the rotary switch to”–“. 3 Switch the pump on. Do not set the set-point value higher than 250 °C. Leak-stop mode with the RT50 controller Pressing the “Leak Stop” key switches the unit to leak-stop mode. Leak-stop mode is possible only when the setpoint value is between 0 and 250 °C (see “RT50 Operating Instructions”, Section 7.2, item 4.4). Suction with the RT30 controller 1 Switch the unit off as described in Section 5.1. 2 Set the rotary switch to ”–“. 3 Switch the pump on. 4 Keep the rotary switch in the “A” position to evacuate the consumer. Suction with the RT50 control system Pressing the “Suction” key initiates the suction program. The consumer connected to the unit will be evacuated. Suction is possible only when the medium temperature S1 lies below the programmed pump run-out temperature (see “RT50 Operating Instructions”, Section 7.2, item 4.3). If this is not the case, the unit will cool to this temperature before initiating the program. The suction procedure and the leak-stop function can be interrupted by pressing the “ON/OFF” key. Pressing the “ON/OFF” key again will return the unit to normal mode. During leak-stop mode, the set-point value shall not exceed the run-out temperature (“RT50 Operating Instructions”, Section 7.2, item 4.3). 10.2 Flow measurement (RT50 only) Using the 䉴 key, move to “Display actual value”. Press the same key again to read the flow rate. To return to the operating level, press the same key once more. 11. Troubleshooting For RT30 controller malfunction messages, see Section 4.1.2. For RT50 control system malfunction messages, see the “RT50 Operating Instructions”, Section 6. 3.

Key for setting the set-point value and programming Increase and decrease the set-point value and change programmed values. Timer key Activates the timer, when present. The timer turns the controller on and off. PA RT50 0309/e 1 Leak-stop key Pressing this key will switch the unit over to leak-stop mode. Leak-stop mode is possible only when: If water is the heat transfer fluid, the set-point value should lie in the runout temperature range (Section 7.2, P 4.3) of 0 to 80 °C max. If oil is the heat transfer fluid, the set-point value should be in the range of 0 to 250 °C. With leak-stop mode and oil, the max. heating capacity is 60 %, to keep the oil’s thermal load due to reduced pump capacity low. Leak-stop mode can be interrupted by pressing the ON/OFF key. Pressing the ON/OFF key again (after waiting for OFF to appear on the display) will return the unit to its normal mode. Suction key Pressing this key initiates the evacuation program. The consumer connected to the unit is evacuated either by the pump via suction or by blowing out with compressed air. Evacuation is only possible when the temperature of the heat transfer fluid is below the programmed runout temperature (Section 7.2, P 4.3). If this is not the case, the unit will cool the heat transfer fluid to this level. The pump is switched off. Once the pump’s run-down time (Section 4.9) has elapsed, the pump is switched on again in the opposite direction of rotation. It then empties the consumer during the programmed value for evacuation time (Section 7.2, P 4.6). The blow-out program using compressed air is activated once the pump’s run-down time has elapsed. After the programmed evacuation time, the unit will switch itself off automatically. The suction and blow-out programs can be interrupted by pressing the ON/OFF key. Pressing the ON/Off key again (after waiting for OFF to appear on the display) will return the unit to its normal mode. Note: In pressurised water units, the pressure relief valve closes 5 °C above the value runout temperature, i.e. at max. 85 °C, and opens at the programmed runout temperature during the cooling process. Alarm reset key Functions: Manual resetting of the alarm relay (e.g. horn switched off). As soon as the malfunction has been corrected, the alarm display can be switched off by pressing this key once more. Manual acknowledgment of the automatic switch-over from consumer temperature control or cascade control to outlet temperature for defective or missing sensor S2. SP key Switch-over from set-point value 1 (SP1) to set-point value 2 (SP2) and vice versa. The set-point values can also be activated by an external digital signal. A switch-over can only take place if no alarm is active. Operation with code To prevent the set or programmed values from being changed inadvertently, we strongly recommend the use of a code. There are four possibilities: - Code input value - Code set-point value - Code user setting 1 - Code user setting 2 They can be programmed as described in Section 7.2, P 15. The input value code for the RT50 is set to 50 at the factory. Save/Reset for factory and user settings The RT50 control system offers the possibility to change the factory setting simply and at any time. In the same way, two different customer-specific settings can be reloaded (user settings 1 and 2). Programming is described in Section 7.2, P 14. 4. Switching on Once the main switch has been turned on, OFF will appear on the display. The RT50 is now ready for operation. Switch the unit on by pressing the ON/OFF key. Depending on the programming, the set-point and actual values as well as information on the operating condition of the control system and unit. See also Section 6. If the unit is equipped with the suction equipment and the phase sequence is wrong, two phases are switched automatically, so that the pump operates in positive pressure mode. 2 PA RT50 0309/e 5. Switching off The switching off procedure is initiated by pressing the ON/OFF key or by the timer. The switching off program runs automatically as follows, depending on the temperature of the heat transfer fluid: - Pump and control system are switched off. The RT50 is still powered (stand-by mode). The display shows OFF. - The pump continues to run. The unit cools until the temperature of the heat transfer fluid reaches the programmed run temperature (Section 7.2, P 4.3). The pump and controller are then switched off. The RT50 stays in stand-by mode. The display indicates OFF. 6.

Programming example The sheet entitled “Programming example” shows the entry of an individual code and the programming of the deviation between set-point value and actual value. See also sheets entitled “Menu RT50” and “Temperature limit values” in the Appendix. Entering the value 5 °C means that when the actual value exceeds the set-point value entered, the alarm Deviation Setpoint/Actual will appear on the controller display. 9. Types of control The RT50 control system works with the following computer programs (control algorithms): - PID control to outlet, inlet or external sensor. For this type of control, there are 10 fixed parameter sets for each of heating and cooling as well as a manual set. Cascade control with external and outlet sensors or outlet and inlet sensors. This type of control also has 10 fixed parameter sets as well as a manual set. 9.1 Fixed parameter sets To save the operator the time-intensive determination of the P, I und D control parameters for heating and cooling, the fixed parameter set which best matches the application can be loaded. In most cases, the operator can determine the best fixed parameter set for his application, by following these simple rules: 1. Basic setting: Parameter set 5 2. If the set-point value entered is not attained after a reasonable amount of time, the next lower parameter set should be selected (Example parameter set 4 instead of 5). 3. If the actual value exceeds the set-point value, or the set-point oscillates, the next higher fixed parameter set is chosen. If none of these parameter sets results in the desired control, because the controlled system deviates from the standard, an individual set can be entered. Note: The set-point is reached most quickly when the actual value exceeds the set-point a bit. If an overshoot is not acceptable, the operator must expect a somewhat longer heat-up time. 9.2 Fixed cascade set Notes and procedure as described in Section 9.1. 10. Operation with data interface (optional equipment) Control of the unit from the process control computer by connecting the “unit/process control computer”.
