9.5 Thermal motor protection
● r4620[0...3] ≠ -200° C means:
– a KTY84 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 is deactivated
– the temperature evaluation is 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.
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
Bimetallic NC contact
● p4100[0...3] = 4 sets the temperature sensor type bimetal NC contact, 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
