EBM The SBM function of the twin-head pump can be configured so that the SBM con-
tacts 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 assigned.
An SSM/SBM relay forced control is used as function test of the SSM/SBM relay and elec-
trical connections.
