Settings menu 1: General
Use this menu to make settings that apply to the whole device and
therefore to all channels.
1.Fault memory
Faults that only occur temporarily can be saved.
ON
After the cause of fault has been eliminated, all alarm
messages remain saved until a RESET is carried out. This
function relates to alarm and device error messages.
off
EDS460-DG exits the alarm status as soon as the cause
of the error is eliminated.
2.Trigger
The IRDH575 / PGH... test current pulse is synchronised with the
EDS460-DG measurement technique. The EDS460-DG is told when to
expect a test current pulse. This means that test current pulses can still
be reliably detected in the event of interference. Sources for interference
include, for example, variable-speed drives, power converters, actua-
tors, suppressor filters, PLCs or control electronics.
Choose:
Com
Synchronisation via BMS bus. The EDS460-DG will only
begin searching for insulation faults when insulation
fault location has been started. It knows when to expect
the test current pulse. Insulation fault location is per-
formed more quickly than with the "auto" setting.
auto
No synchronisation (e.g. if there is no BMS bus). The
EDS searches continually for insulation faults.
3.Rated frequency
Set the rated frequency of the system being monitored. The EDS460-DG
must always be set to "DC" (factory setting). This must be set correctly,
otherwise the EDS460-DG will not be able to evaluate the test current
pulse accurately.
