When the insulation resistance from system to ground falls below the set response value,
the alarm relays switch and the alarm LEDs activate. Two separately adjustable alarmcontacts
can be set to a prewarning and main warning alarm. The measured value is indicated
on the LCD display or an externally connectable measuring instrument.
