Collective fault signal SSM
Faults always result in the activation of the collective fault signal "SSM" via a relay. The contact of the col-
lective fault signal (potential-free normally closed contact) can be connected to the system for the purpose
of registering any error messages that may occur.
The internal contact is closed if the pump is without power, if there is no fault or if there is a malfunction of
the control module.
The internal contact is open if the pump detects a fault.
The detailed behaviour of the SSM function is described in the section "Faults, causes and remedies".
