The insulation fault alarm has been deactivated but not
acknowledged.
The smallest value measured during the fault, the alarm limit's
set value and the fault start time are displayed.
The
Insulat.
and
PreInsul
alarms are active if the measured insulation resistance is
smaller than the alarm or pre-alarm limit.
The
Sys Test
alarm is active if the manual system test fails. In that case, the insulation
resistance can not be measured either, so an insulation resistance alarm is also given.
The
GND Fail
alarm is active if the TG or MG wire of the IM-01.IND unit is disconnected.
In that case, the insulation resistance can not be measured either, so an insulation
resistance alarm is also given.
The
WireAmpl
or
WireOffs
alarm is activated if the M1 or M2 wire of the IM-01.IND
unit is disconnected or the insulation resistance is short-circuited. In that case, the
insulation resistance can not be measured either, so an insulation resistance alarm is
also given.
The
MeasFail
alarm is active if the system is unable to measure the insulation
resistance. In that situation, an insulation resistance alarm is also always given. Reason
for the fault may be, for example, capacitance that is too high.
The
Noise
alarm is active if network disturbances are too extensive for the selected
Filter setting.
The
Temp Lim
alarm is active if the temperature of the isolation transformer is too high.
The
T-sens 0
alarm is active if one of the measurement wires of the NTC/PT100 sensor
measuring the temperature of the isolation transformer has been disconnected from the
IM-01.IND unit.
The
T-sens S
alarm is active if the wires of the NTC/PT100 sensor measuring the
temperature of the isolation transformer are short-circuited.
The
Load Lim
alarm is active if the secondary current of the isolation transformer is too
high.
The
L-sens 0
alarm is active if one of the measurement wires of the current transformer
measuring the output current of the isolation transformer has been disconnected from
the IM-01.IND unit.

Installation and User Manual.
The
Memory
alarm is active if writing on the memory card fails or the card has been
removed. These alarms are activated only if the memory card has been enabled in the
SETUP menu.
The
ClockErr
alarm is active if the operating voltage of the real time clock circuit has
been too low. The fault is caused by a depleted battery. The fault can only be
acknowledged once the time has been set. The device battery cannot be changed by the
