11.1 CONNECTION OF TEMPERATURE SENSOR
Connection of the temperature sensor depends on the type of sensor used and varies for Pt100 or
thermocouple (see Figure 3). For connection purposes, a shielded cable must be used. For a thermo-
couple, an appropriate compensating cable conforming to DIN 43714 must additionally be used.

OPERATING PRINCIPLE
Operating and programming of the controller takes place on two levels. On the first level for normal
operation, alarms can be reset or in case of starting up a control circuit, self-optimizing is activated.
Underneath there is the user level. All of the important adjustments of the controller are combined on
the user level and can be changed after removing the level inhibit.
12.1 PARAMETER OF THE USER LEVEL WITH FACTORY SETTING
Setpoint SP, factory setting = 180°C
•
Max. excess temperature difference to the setpoint ALSE, factory setting = 10°C. In case of
•
exceeding, a cut off of the controller with lock and an alarm signal takes place.
Max. low temperature difference to the setpoint Lo-t, factory setting = 10°C. In case of falling
•
below, an alarm signal takes place
Limit comparator Lfun, factory setting = 2 : for controller with ramp function, 6 : for controller
•
without ramp function, other values are not adequate for the operation of M&C products
Function of the controller Fnct, factory setting = 1: ramp function, 0 : fixed-setpoint controller.
•
Other values are not adequate for the operation of M&C products.
Ramp slope resp. increase of temperature in °C/min (°F/min) rASL, factory setting = 30
•
Sensor type SenS, factory setting = 2: Resistance thermometer in 2-wire circuit
•
0: no function
1: Resistance thermometer in 3-wire circuit
2: Resistance thermometer in 2-wire circuit
4: Thermocouple
