Alarm and its effect
Cause of the alarm
Insulation fault
•
The insulation resistance is below both response values
LEDs ALARM 1 and ALARM 2 flash.
Device error
•
LED SERVICE flashes.
Active insulation fault location
•
LED PGH ON blinks according to the locating current.
Device signals alarm or device error
Display indicates error and, where applicable,
•
the measured value.
In the event of "ALARM 1" or "ALARM 2", the associated LEDs
•
flash.
A warning sound beeps at intervals, if assigned.
•
Assigned alarm relays will switch.
•
Assigned digital outputs will switch.
•
Reset alarm messages (Reset)
Requirement: The cause of the alarm is no longer present. The in-
sulation resistance must be at least 25 % higher than the re-
sponse value.
Select: "RESET" > "RESET" > "OK".
