The following parameters can be changed in the Setup menu:

•

INSULATION LIMIT

: Alarm limit of the insulation resistance. If the measured

value is lower than the alarm limit, an alarm is given. The setup range is 50

kΩ…1,000 kΩ. It can be set at 50 kΩ intervals.

•

PRE INSULATION LIMIT:

The pre-insulation limit of the insulation resistance.

Given as a percentage of the insulation limit. Activates the AUX. ALARM relay,
unless it is removed from the AUX alarm mask. The setup range

is 100…200%, at

10% intervals.

•

Filter:

High, Medium or Low. Must be set according to the network frequency:

20

–

400 Hz

High

10

–

20 Hz

Medium

1

–

10 Hz

Low

•

Max Cap:

<20uF or >20uF. Must be set according to the maximum capacitance

existing at the network to be monitored. This parameter affects how the
insulation level measurement functions during a short-circuit condition.

•

TEMPERATURE LIMIT:

The alarm limit of the transformer temperature. Can be

set between 30…140 °C or switched OFF if temperature measurement is not

used.

•

TEMPERATURE SENSOR TYPE:

The type of the temperature sensor used (NTC

or PT100).

•

PT100 CALIBRATION:

This setting is only used when PT100 is selected as the

temperature sensor. It can compensate for the error caused by long

measurement wires (the maximum loop resistance is 20 Ω) in the temperature
value. A 130 Ω resistor is connected to the end of the measurement wires in the

place of the PT100 sensor, after which calibration is performed:

If the resistance measured in calibration is too low or too high, the message
displayed is Failed, instead of Cal.OK. In that situation, check the connection.
