OPERATING PRINCIPLE
Operating and programming of the controller takes place on two levels. On the first level for normal operation,
alarms can be resetted or in case of startup a control circuit, self-optimising is activated.
Underneath there is the user level. All 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
cutoff 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
3: Resistance thermometer in 4-wire circuit
4: Thermocouple
5: resistance transmitter
6: Heater current 0...50 mA AC (analog input 2 only)
7: 0...20 mA
8: 4 ... 20 mA
9: 0...10 V
10: 2...10 V
11: 0 ... 1 V
