Monitoring functions and protective functions
10.2 Thermal motor protection
● r4620[0...3] ≠ -200° C means:
– A KTY84/PT1000 is connected.
– The temperature display is valid.
● r4620[0...3] = -200° C means:
– A PTC or a bimetal NC contact is connected.
– There is a temperature sensor fault.
– The sensor channel has been deactivated.
– The temperature evaluation has been deactivated.
KTY84
● p4100[0...3] = 2 assigns the temperature sensor type KTY84 to a corresponding channel 1
to 4, and activates the evaluation.
● r4105[0...3] displays the actual temperature value of the measuring channel involved of the
temperature evaluation. If no sensor has been selected or if the actual temperature value is
invalid, the value -300° C is in the parameter.
PT1000
● p4100[0...3] = 6 assigns the temperature sensor type PT1000 to a corresponding channel
1 to 4, and activates the evaluation.
● r4105[0...3] displays the actual temperature value of the measuring channel involved of the
temperature evaluation. If no sensor has been selected or if the actual temperature value is
invalid, the value -300° C is in the parameter.
PTC
● p4100[0...3] = 1 sets temperature sensor type PTC to the corresponding channel 1 to 4, and
activates the evaluation.
● r4105[0...3] displays the actual temperature value of the temperature evaluation.
– If the actual temperature value is lower than the rated response temperature, then
– If the actual temperature value is higher than the rated response temperature, then
– If no sensor has been selected or if the actual temperature value is invalid, then
