8.2 (2 ) EDS (insulation fault location only for isoxx1685DP)
8.2 (2.1) General
8.2 (2.1.1) Mode
To locate insulation faults, select one of the following three available modes for insulation
fault location.
For insulation fault location, the protocol of the RS-485 interface must be set
to BMS (menu 8.2 (6.3) "Interface"
) . Insulation fault location via the Modbus
RTU protocol is not possible.
•Manual
In manual mode, the insulation fault location starts immediately. If the insula-
tion fault location is started, it remains active without considering the insula-
tion 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® falls below the preset value. The
insulation fault location is cyclically interrupted for an insulation measure-
ment. If the insulation fault still exists after the interruption, the insulation
fault location starts again. The insulation fault location only stops when 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® falls 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.
