The ISOMETER® cannot switch on a potential termination at the BMS
bus. Even though this is not expected to cause communication
problems, the ISOMETER® should be operated as BMS slave if possible
(BMS address > 1).
If no other device with master capabilities is available on the bus, the
ISOMETER® can be set to master (BMS address 1).
Before the ISOMETER® takes over the backup master function after
being switched on, it waits to see if another master connects to the
system.
Waiting period: BMS address minus 1 = waiting period in minutes.
Example: The iso1685DP has BMS address 3. It waits 3 minus
1 minutes (= 2 minutes) for a master to connect.
The A4 switch of the dip switch SS8103 is used to switch between BMS
and Modbus (refer to
on page 40).
