5.2 Switching on
1. Connect the supply voltage of all devices connected to the BMS bus.
Initially, the "ON" LED flashes on the EDS… and the EDS…-D graphic
display shows the (Bender) welcome screen. The "ON" LED then lights
up permanently.
2. Eliminate insulation and device errors. If a response value is exceeded
or device error messages occur, this is indicated on the EDS… by
means of the alarm LED lighting up and an associated message appea-
ring on the graphic display (EDS…-D only).
– You can find information about the alarms on the EDS…-D in the
"Alarm/Meas. values" menu. Information on the EDS…-L can be dis-
played via the BMS master.
– Eliminate the insulation faults detected by the EDS….
– The EDS…-D indicates any device errors that have occurred on its
display, the EDS…-L displays an error code.
– Device errors may be caused by measuring current transformers
not being connected. Check the measuring current transformer
connections. Disable transformer monitoring for measuring chan-
nels that are not required (refer to Chapter 6.6.3.2 "Settings menu 2:
Channel", submenu „2.CT“ on page 52).
8. In respect of the BMS bus node address settings, has each
address only been assigned once? Is address 001 and
therefore the master function, assigned?
Due to the synchronisation processes on the BMS bus,
current alarm messages may not be available for a short
time. If however, the causes of the alarms are still present,
the alarm messages will reappear after a few seconds.
