6.6 EDS-SETUP menu: Settings for fault location
This menu allows to carry out the necessary settings for the insulation fault lo-
cation system (EDS).
6.6.1 EDS auto / on / off / pos / 1cycle
A selection of the start and stop conditions for EDS systems and their meaning
are listed below:
 
on
The EDS is running continuously, regardless of the insulation value and
the alarm messages from the ISOMETER®. This setting is essential, for
example, for mobile insulation fault location systems such as EDS3060/
3360.
 
off
The EDS system is constantly switched off.
 
pos470 (EDS47… only)
For continuous measurement at a desired address (EDS4…-12) and a
certain channel. The selected parameters are kept until a new operat-
ing mode is set.
This function is only possible in the Master mode (bus address 1).
The following messages are possible in the POSITION mode.
Note: the messages noCT and short are only generated when the CT
monitoring for the respective channel has been switched on (= factory
setting, menu CT SETUP):
– no EDS:
no EDS47… of this address available
– no Alarm: no insulation fault detected
– … mA: indication of the fault current in case of an insula-
tion fault
– >1A/>10 A: AC residual current > 1 A (EDS473) or >10 A
(EDS470)
– peak fault: measurement disturbed
– short: CT input short-circuited
– noCT: no CT connected
