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
terminal program.
In order to be able to locate insulation faults, select one of the four available modes for
insulation fault location by means of the BMS gateway (e.g. COM460IP) or terminal pro-
gram via the BMS bus or Modbus.
off
The insulation fault location is deactivated.
manual
In manual mode, the insulation fault location starts immediately. If you start the
insulation fault location, it remains active without considering the insulation
resistance and the alarm message of the ISOMETER®.
auto
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 measurement. 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 inactive. If a new
insulation fault appears, the insulation fault location restarts automatically.
1 cycle
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 location
does NOT start again. If a new insulation fault appears, the insulation fault loca-
tion restarts automatically for one cycle.

7.5 Deactivating the device
When the device is deactivated, the coupling unit of the device (isoPV1685P only) is gal-
vanically isolated from the system being monitored.
The device can be activated or deactivated via the BMS channel 10:
•
Activate the standby mode using the BMS command STDBY 1
•
Deactivate the standby mode using the BMS command STDBY 0
•
Query the current state using the BMS command TRSH? 10
The standby mode of the isoPV1685P, for example, allows team operation of inverters,
since only one insulation monitoring device may be connected in each interconnected
system.
7.6 Resetting alarm messages
Recorded faults are provided as alarm messages on the BMS bus and the CAN bus.
Pressing the reset button ST6101 will reset these alarm messages. If the fault continues to
exist, the message will be generated again.
The fault can also be reset by means of the acknowledgement command via the CAN bus.
