5.2 Switching on
1. Connect the supply voltage of all devices connected to the BMS bus.
Initially, the "ON" LED flashes on the RCMS… and the RCMS460…-D
graphic display shows the (Bender) welcome screen. The "ON" LED
then lights up permanently.
2. Set the BMS bus addresses. Never assign one address twice. Check, if
address 001 and thus the master function has been assigned.
3. Select the language (see page 71).
4. Set the CT type for each channel (page 66).
5. Start the preset function (see page 56).
6. Switch off unassigned measuring channels to avoid device errors (see
page 63).
7. Fault messages may be caused by measuring current transformers not
being connected. Check the measuring current transformer connec-
tions. Switch off the CT monitoring of the measuring channels not cur-
rently used (see page 67).
8. Eliminate insulation faults and the associated fault messages. If a res-
ponse value is exceeded or device error messages occur, this is indica-
ted on the RCMS… by means of the alarm LEDs lighting up and an
associated message appearing on the graphic display (RCMS…-D
only).
– You can find information about the alarms on the RCMS460…-D in
the "Alarm/Meas. values" menu. Information on the RCMS…-L can
be displayed via the BMS master.
– Eliminate the insulation faults detected by the RCMS. Check whe-
ther the set response values are correct and practical for this sys-
tem. If you want to readjust all response values, use the preset
function of the device.
– The RCMS…-D displays any device errors that have occurred. The
RCMS…-L… displays an error code. If a device error continues to
exist after a reset has been carried out, the RCMS… has to be
replaced.
