Table 35: Function SBM relay
NOTICE
If SBM is set to "Motor in operation", the SBM relay switches when No-Flow Stop is
active.
If SBM is set to "Ready for operation", the SBM relay does not switch when No-Flow
Stop is active.
After confirming one of the selection options, the SBM trigger delay and SBM reset
delay are entered.

Table 36: Trigger and reset delay
ƒ
Triggering of the SBM signal after changing an operating status is delayed.
ƒ
Resetting of the SBM signal after changing the operating status is delayed.
Trigger delays are used so that processes are not influenced by very brief changes in the
operating state.
If an operating state change can be reversed before the end of the set time, the change
is not reported to the SBM.
A set SBM trigger delay of 0 seconds reports an operating state change immediately.
When an operating status change occurs only for a short duration, the reset delay pre-
vents a flutter of the SBM signal.
NOTICE
SBM trigger and SBM reset delay is set to 5 seconds as a factory setting.
SBM/EBM (collective run signal/individual run signal) in twin-head pump operation
ƒ
SBM The SBM contact can be assigned to any of the two pumps. Both contacts sig-
nal the operating status of the twin-head pump in parallel (collective run signal).
ƒ
EBM The SBM function of the twin-head pump can be configured so that the SBM
contacts signal only operational messages of the respective pump (individual run
signal). In order to record run signals of both the pumps, both contacts must be as-
signed.
A SSM/SBM relay forced control is used as function test of the SSM/SBM relay and elec-
trical connections.
In the "Diagnostics and measured values" menu
1. "Diagnostics help"
