Parameter Setting Of The Insulation Fault Location; (Isopv1685P Only) - Bender ISOMETER isoPV1685RTU Manual

7.4 Parameter setting of the insulation fault location

(isoPV1685P only)

Set the value of the locating current required for insulation fault location to 1...50 mA. You
can make this setting via the BMS bus by means of a BMS gateway (e.g. COM460IP) or a ter-
minal program.
In order to be able to locate insulation faults, select one of the four available modes for in-
sulation fault location by means of the BMS gateway (e.g. COM460IP) or terminal program
via the BMS bus or Modbus.
off
The insulation fault location is deactivated.
In manual mode, the insulation fault location starts immediately. If you start
manual the insulation fault location, it remains active without considering the insula-
tion resistance and the alarm message of the ISOMETER®.
In auto mode, the insulation fault location starts automatically as soon as the
response value of alarm 2 of the ISOMETER® has fallen below the preset value.
The insulation fault location is cyclically interrupted for an insulation measure-
auto
ment. If the insulation fault still exists after the interruption, the insulation fault
location starts again. The insulation fault location only stops if alarm 2 is inac-
tive. If a new insulation fault appears, the insulation fault location restarts auto-
matically.
In 1-cycle mode, the insulation fault location starts automatically as soon as
the response value of alarm 2 of the ISOMETER® has fallen below the preset
value. The insulation fault location is stopped after one cycle.
If the insulation fault still exists after the interruption, the insulation fault loca-
tion does NOT start again. If a new insulation fault appears, the insulation fault
location restarts automatically for one cycle.
