Functions, monitoring, and protective functions
9.4 Monitoring and protective functions
The following applies for the alarm thresholds:
● If the temperature actual value associated with a channel exceeds the set alarm threshold
(r4105[x] > p4102[2x]), the corresponding alarm is output. Timer p4103[0...11] is started
at the same time.
● The alarm remains until the temperature actual value (r4105[x]) has reached or fallen
below the alarm threshold (p4102 [2x]) - hysteresis (p4118 [x]).
● If, after the timer has expired, the temperature actual value is still above the alarm
threshold, then the appropriate fault is output.
The following applies for the fault thresholds:
● If the temperature actual value associated with a channel exceeds the set fault threshold
(r4105[x] > p4102[2x+1]), the corresponding fault is output.
● The fault remains until the temperature actual value (r4105[x]) has reached or fallen
below the fault threshold (p4102 [2x+1]) - hysteresis (p4118 [x]) and the fault has been
acknowledged.
Using p4119[0...11], for each channel, a filter can be activated to smooth the temperature
signal.
The time constant of the filter depends on the number of active temperature channels and
can be read in r4120.
Failure of a sensor within a group
Using parameter p4117[0...2], the response to the failure of a temperature sensor can be set
within a group:
● p4117[x] = 0: The failed sensor is not taken into account in the group.
● p4117[x] = 1: When a sensor fails, for the maximum value, minimum value and the
average value of the group, a value of 300 °C is output.
