Operation and setting
6.4 ISO SETUP menu: Setting of the basic ISOMETER®
functions
The response values (Alarm 1/2, prewarning and main alarm), the operating
principle of the alarm relays K1 and K2 (N.O = N/O operation, N.C = N/C ope-
ration), the fault storage behaviour and the selection of the current output
between two different ranges are set in this menu.
6.4.1

Response values Alarm 1 and Alarm 2

The response values Alarm 1 and Alarm 2 are selected with the UP/DOWN
keys and stored with the ENTER key.
6.4.2 Starting the EDS system via the response values ALARM 1
and ALARM 2
The EDS system is started when the value of the insulation resistance falls
below the lowest preset response value, i.e. below both alarm values.
When setting the ISOMETER® response values, make sure that the lower value
of them is within a range which the EDS system is able to find. Therefore it is
recommended to set the ISOMETER® response value according to the respon-
se characteristic curves of the EDS system (Refer to page 102).
