5 Configuration
5.1.5 Monitoring
This allows an internal measured value to be monitored for compliance with
limit values.
Depending on the switching behavior, an overrange or underrange is output at
the binary output (option: relay or optocoupler).
Value/settings Description
Limit value moni-
toring Switched off No monitoring
Load voltage These measured values can be monitored and are dependent
on the ordered device type.
Note: (as of software version 256.01.08)
If power controller -> SCR control -> Logic (switch) and Moni-
toring -> Limit value monitoring -> Load voltage, load current,
power (in W) or power (in kW) is set,
the limit value monitoring only operates in the periods in which
the SCRs have been fired.
If the SCRs block, as a general rule, the min. and max. alarms
are switched off.

Min. limit value
alarm 0 to 9999.9 The absolute minimum limit value for load voltage, load cur-
rent, power, resistance, supply voltage, or device temperature
can be monitored.
If the measured value falls below this value, an error message
appears at the bottom of the display and the yellow K1 LED
lights up. Depending on the set control direction, the binary
output switches as shown in the diagram.
The unit of the limit value corresponds to the monitored mea-
sured value.
Max. limit value
alarm 0 to 9999.9 The absolute maximum limit value of load voltage, load cur-
rent, power, resistance, supply voltage, or device temperature
can be monitored.
If the measured value exceeds this value, an error message
appears at the bottom of the display and the yellow K1 LED
lights up.
Depending on the set control direction, the binary output
switches as shown in the diagram.
The unit of the limit value corresponds to the monitored mea-
sured value.
