Control input "Analogue In 0 ... 10 V" without cable break function
The pump is controlled according to an analogue signal in the range of 0 ... 10 V. Be-
haviour when a cable breaks: If the signal cable is disconnected from the pump, e.g.
due to a cable break, the pump stops.

Collective fault signal SSM
Faults always result in the activation of the collective fault signal "SSM" via a relay.
The contact of the collective 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.
