 The MUTE ALARM button silences the audible alarm. It does not have any other
effect on the functioning of the system as a whole.
 The TEST TEMP. button switches the load display to a temperature display. The
display blinks when the button is pressed and indicates the temperature in
relation to the alarm limit given. When the button is released, the display returns
to the load display.
INSULATION RESISTANCE AND TRANSFORMER REMOTE
ALARM UNIT RD-01
The alarm unit of the insulation resistance and transformer RD-01 gives an alarm if the
system’s insulation resistance is lower than the limit provided, or if the earthing wire
resistance measured by any PEC-01 unit exceeds the limit provided, or if there is a break
in the wire. It also gives an alarm if the transformer’s load current or temperature limit
is exceeded. Alarm limits can be issued for all parameters through the SETUP menu in
the IM-01.MED unit. RD-01 also gives an alarm if it is not connected to the IM-01.MED
unit. In addition, the unit issues a warning if the system's insulation resistance is lower
than the pre-alarm limit set.
 The OK LED is on if the unit functions normally and off if any fault is active. In
other words, at least one LED indicator is on in the unit at all times.
 The WARNING LED blinks if the insulation resistance drops below the pre-alarm
limit. The alarm is deactivated and the LED is on steadily when insulation
resistance rises 5% above the pre-alarm limit. The pre-alarm limit is set as a
percentage of the alarm limit in SETUP

PrInsLim.
 The ALARM LED blinks if the insulation resistance is lower than the limit provided,
if the transformer’s load current or temperature limit is exceeded or if the
