5 Configuration
5.1.6 Monitoring
This allows an internal measurand to be monitored for compliance with limit
values.
Depending on the switching behavior, an overrange or underrange is output at
the digital output (option: relay or optocoupler).

Mains current
Min. alarm limit val-
ue 0 to 9999.9 Absolute minimum limit values for load voltage, load current,
power, load resistance, DC intermediate circuit voltage, device
temperature, or mains current can be monitored.
If the measurand falls below this value, an error message ap-
pears at the bottom of the display and the yellow K1 LED
lights up. Depending on the set control direction, the digital
output switches as shown in the diagram.
The unit of the limit value corresponds to the measurand to be
monitored.
Max. alarm limit
value 0 to 9999.9 Absolute max limit values for load voltage, load current, pow-
er, load resistance, DC intermediate circuit voltage, device
temperature, or mains current can be monitored.
If the measurand exceeds this value, an error message ap-
pears at the bottom of the display and the yellow K1 LED
lights up.
Depending on the set control direction, the digital output
switches as shown in the diagram.
The unit of the limit value corresponds to the measurand to be
monitored.
Limit value
hysteresis 0 to 1 to 9999.9 Switching differential at the upper and lower limit of the moni-
toring range
