«SUCTION» key for suction/evacuation - Suction, configuration Suct. = Pu. This function is possible only if the temperature of the heat transfer fluid is below the value P.tE. (factory setting: unit specific). If this is not the case, the temperature control unit will first cool the fluid to this value. The «ON/OFF» LED will blink and the «SUCTION» key LED will light up. Once P.tE. has been reached, the pump motor will switch off. After the run-out time dt.P. has elapsed (factory setting: 5 s), the pump will run in suction mode during the time period t.Suc. (factory setting: unit specific). To switch suction mode off during this period, press the «ON/OFF» key. Suction mode can be initiated only once while the temperature control unit is switched off (display showing OFF). - Evacuating the consumer, configuration Suct. = P.AIr. This function is possible only if the temperature of the heat transfer fluid is below the value P.tE. (factory setting: unit specific). If this is not the case, the temperature control unit will first cool the fluid to this value; the «ON/OFF» LED will blink and the «SUCTION» key LED will light up. Once P.tE. has been reached, the temperature control unit will switch to drainage mode during the time period t.Suc. (factory setting: unit specific). Note: When setting t.Suc. = 0, the temperature control unit will cool to the value P.tE. and switch off. Press the «ALARM RESET» key to reset the acoustic alarm and alarm display manually.

4. Switching on

4.1 Initial installation/Filling the heat transfer fluid

Switch the main power switch on at the temperature control unit. Once the unit’s main switch has been actuated, the RT60 control system will run a functional test for approximately 3 s. During the test, four dots will appear in each of the display fields. Once the test has been successfully completed, the dots will disappear, and the RT60 is ready for operation. Using water as the heat transfer fluid: The refill valve opens independently of the RT60’s operational status. OFF will appear in the upper display field. After the «ON/OFF» key is pressed, the set-point temperature SP will appear in the lower display field, and the actual temperature S.1 of the internal sensor S1, will appear in the upper display field. Cooling is activated in accordance with the set-point value. As long as sufficient heat transfer fluid circulates in the temperature control circuit, the pump will continue to run without interruption. Enter the desired set-point value using the keys. If the required level of heat transfer fluid is not attained by the end of the time period d.t.L. (factory setting: unit specific), a warning message, FILL Err, will appear in the display. Security code: To prevent the set/programmed values from being changed inadvertently, we strongly recommend using a security code (see 7.14). The RT 60/unit security code is set to 60 at the time of delivery. 4.2 Subsequent usage

Switch on the main power switch at the temperature control unit. Once the unit’s main switch has been actuated, the RT60 control system will run a functional test for approximately 3 s. During the test, four dots will appear in each of the display fields. Once the test has been successfully completed, the dots will disappear, and the RT60 is ready for operation. OFF will appear in the upper display field. Switch on by pressing the «ON/OFF» key. The set-point temperature SP will appear in the lower display field, and the actual temperature S.1 of the internal sensor, S1, will appear in the upper display field. Enter the desired set-point value using the keys. Security code: see 4.1 5. Switching off

5.1 By pressing the «ON/OFF» key

Depending on the temperature of the heat transfer fluid, the switch-off program runs automatically as follows: All displays and LEDs turn off, with the exception of OFF in the upper display field. The pump and control system are switched off. The RT60 remains powered in stand-by mode. The «ON/OFF» LED blinks: The pump continues to run. The unit cools until the heat transfer fluid reaches the programmed pump run-out temperature P.tE. (factory setting: unit specific). The pump and control system are switched off. The RT60 switches to stand-by mode. All displays and LEDs turn off, with the exception of OFF in the upper display field. The current set-point value is saved.

5.2 By previous evacuation of the consumer

Press the «SUCTION» key. - Suction: Configuration Suct. = Pu. This function is possible only if the temperature of the heat transfer fluid is below the value P.tE. (factory setting: unit specific). If this is not the case, the temperature control unit will first cool the fluid to this value. The «ON/OFF» LED will blink and the «SUCTION» key LED will light up. Once P.tE. has been reached, the pump will switch off. After the run-out time dt.P. has elapsed (factory setting: 5 s), the pump will run in suction mode during the time period t.Suc. (factory setting: unit specific). To switch the function off during this period, press the «ON/OFF» key. Suction mode can be initiated while the temperature control unit is switched off (display showing OFF). - Evacuation (90smart, 150smart and P140smart not valid): Configuration Suct. = P.AIr. This function is possible only if the temperature of the heat transfer fluid is below the value P.tE. (factory setting: unit specific). If this is not the case, the temperature control unit will first cool the fluid to this value. The «ON/OFF» LED will blink and the «SUCTION» key LED will light up. Once P.tE. has been reached, the pump will switch off. After the run-out time dt.P. has elapsed (factory setting: 5 s), the pump will run in evacuation mode during the time period t.Suc. (factory setting: unit specific). 5.3 By previous operation in leak-stop mode (P140smart: not available)

Press the «LEAKSTOP» key. Once the key has been pressed, the pump motor will switch off immediately. After the run-out time dt.P. has elapsed (factory setting: 5 s), the pump will switch to suction mode. This function is possible only under the following conditions: - Using water: The set-point value must lie within the first P.tE. range (max. 80 °C/unit specific). The temperature of the heat transfer fluid must be below the value P.tE.. If this is not the case, the temperature control unit will first cool the fluid down to this value. During the cooling phase, SP and ILLE will be shown in the display fields. - Using thermal oil: The set-point value must lie between 0 and 155 °C; if it is higher, SP and ILLE will be shown in the display fields. - YES is selected under L.S. When operating with oil, the heating capacity is limited to 60% during leak-stop mode. During leak-stop mode, the leak-stop key LED will be lit. To switch this function off, press the «ON/OFF» key.

5.4 Emergency off by actuating the main power switch

The main power switch serves as an emergency off switch. To block automatic restart, set P.on to no on the «ConF.» level. After the unit is switched on using the main power switch, it must be restarted by pressing the «ON/OFF» switch (see Section 4.2). Modifying the setting: If the P.on setting is changed to YES on the «ConF.» level, the yellow/red knob on the main power switch must be replaced with the black version, which functions as a system switch. 6.

7.3 «Control parameters» level

Security code must be entered prior to any modifications. See 7.14.1. On this level, the operator can choose from 10 fixed control parameter sets and one set of individually selectable parameters. Fixed parameter sets

Fixed parameter sets designed for specific applications can be loaded to save the operator the time-consuming task of determining the P, I, and D control parameters for heating and cooling. If the controlled system deviates from the norm so much that none of these parameter sets provides the desired control, an individualized set can be created. See 7.9, S.rEG. In most cases, the operator can determine the best fixed parameter set for his application without any special knowledge of control engineering by following these simple rules: 1. Basic setting: Parameter set 5 (factory setting). 2. If the set-point value entered is not attained after a reasonable amount of time, the next lower parameter set

should be selected. (e.g. F.PAr. 4 instead of F.PAr. 5). 3. If the actual value exceeds the set-point value (overshooting), or oscillates about the set point, the next lower

parameter set should be selected (e.g. F.PAr. 6 instead of F.PAr. 5). A total of 10 parameter sets for controlling the temperature of the heat transfer fluid are available. Note: The set-point value is reached most quickly when the actual value overshoots the set point a bit. If an overshoot is not acceptable, the operator must expect a somewhat longer heat-up time.
