The "Forced active" setting permanently activates the relay. This means that, for example, a
warning note (light) is permanently displayed/announced.
The "Forced inactive" setting leaves the relay permanently without a signal. No warning note
can be confirmed.
The contact of the collective run signal (SBM, potential-free changeover contact) can be
connected to a building automation system. The SBM contact signals the operating status
of the pump.
•
The SBM contact can be assigned to any of the two pumps. The following configuration
is possible:
The contact is activated when the motor is in operation, power supply is present (net-
work-ready) or no fault is present (ready for operation).
Factory setting: ready for operation. Both contacts signal the operating status of the
twin-head pump in parallel (collective run signal).
Depending on the configuration, the contact is set to NO or NC.
