6.3 Working in operating mode
6.3.1 Standard display
In operating mode, the EDS… waits for insulation fault location to begin. The
schematic representation shows that no alarm message exist on all of the 12
channels( ).
The EDS…-L displays its BMS bus address (e.g. 02). Only the green "Power ON"
LED is lit.
6.3.2 Alarms and their effects
Possible causes of alarm messages include:
 Insulation faults or residual currents > 10 A (EDS460/490) or > 1A
(EDS461/491).
 A measuring current transformer or measuring current transformer
connection fault.
 Device error
The EDS… signals alarm or device error:
 "ALARM 1" LED lights up if the residual current is: > 10 A (EDS460/490)
or > 1 A (EDS461/491) or in the event of a CT connection fault.
 "ALARM 2" LED lights up when an insulation fault is located.
 Assigned common alarm relays switch.
 An alarm message is being sent to the BMS bus.
 EDS…-D: An alarm message is shown on the display. An entry is made
in the history memory.
 EDS…-L: The alarm LED of the affected measuring channel lights up or
