11.5 Technical Data RT 45
Setting range 0 to 420 °C/32 to 788 °F. (SOF 333: –40 to 420 °C/–40 to
788 °F).
Control behaviour PI/PID. Cascade, fixed programmed parameter group or indi-
vidually programmable parameters.
Entry of control parameters By fixed parameter groups, depending on application, or indi-
vidual.
Data storage Serial EEprom with at least 10-year data storage duration.
Timer with lithium battery and approx. 10-year data storage
duration.
Limit values Min. and max. deviation of set value, programmable for con-
sumer and fluid temperature.
Adjustable max. set value.
Monitoring systems Automatic and permanent self-testing of the control system.
Sensor breakage.
Short circuit of sensor (only with Pt 100).
Limit values for temperature and pump motor current. Flow.
Level. Function of heating and pump contactors.
Inputs
Temperature sensors Sn1: Pt100.
Sn2*: Pt100 or J (Fe-CuNi), K (NiCr-Ni) or T (Cu-CuNi).
Sn3*: Pt100.
External set value input* Standardized, scalable analog interface with 0/4 to 20mA or 0
to 10 V. Electrically insulated internally.
External heating/cooling command* Via potential-free contacts.
Interface* See “Interfaces”
Set value switch-over (value 1/2) At the controller or by external signal.
Outputs
Heating/cooling Triac output for contactors or for solid state relay.
Heating and cooling cycle can be adjusted individually.
Common alarm* Relay 230 V/2 A, potential-free.
Alarm relay* On/off control or operating state of the time switch (on/off).
Recorder outputs 1 and 2* Electrically insulated. With scalable signal 0/4 to 20 mA or 0
to 10 V.
Actual or set value signal programmable.
Sensor output* Recorder output 2 can be programmed as sensor actual
value (thermocouple J, K or T).
