Bender ISOSCAN W Series - Switching on; Steps for Commissioning ISOMETER and EDS

ISOSCAN® EDS440 and EDS441
•
When mounting the measuring current transformers any magnetic fields nearby that could cause
interference are taken into account.
•
When the addresses of the BS bus nodes were set, no address was assigned twice. The ISOMETER® with
integrated locating current injector (e.g. ISOMETER® iso685-D-P) is set as master.
6.3 Switching on
1. Switch on the supply voltage of all devices connected to the BS bus or the BB bus.
u
The “ON” LED of the EDS44… flashes at first and then lights up continuously.
2. Eliminate all displayed insulation faults and device errors via the ISOMETER®. If the response values for
prewarning and main alarm are exceeded, the the EDS44…-L indicates the respective alarm message by
lighting up the alarm LED “ALARM I
ΔL
” or “ALARM I
Δn
” (see “Alarm messages”, page 56).
– Further information regarding fault messages on the EDS44… can be displayed via the ISOMETER®.
– Device errors may be caused by measuring current transformers not being connected. Check the
measuring current transformer connections. Disconnect the channels that are not required in the menu
of the ISOMETER®.
Pending alarm messages may temporarily not be available due to synchronisation processes on the BS
bus. However, if the cause of the alarm persists, the alarm messages reappear after a few seconds.
