5. Parameter overview
5.1 Response value setting
The two parameters that monitor the insulation resistance are "R1" and "R2". 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 value (see table below), the alarm will be cleared.
The two parameters ("U <" and "U >") for monitoring the system voltage can be activat-
ed or deactivated. The maximum undervoltage value is limited by the overvoltage val-
ue.
