5.3 "AL" menu
5.3.1 Response value setting
The two parameters that monitor the insulation resistance
R
F
, "R1" and "R2", can be found
in the response value menu "AL". The value R1 can only be set higher than the value R2.
If the insulation resistance
R
F
reaches or falls below the activated values R1 or R2, this
leads to an alarm message. If
R
F
exceeds the values R1 or R2 plus the hysteresis (see table
below), the alarm will be cleared.
The parameters ("U <" and "U >") for monitoring the mains voltage can also be activated
or deactivated in the "AL" response value menu. The maximum undervoltage value is
limited by the overvoltage value.
