• SSM/ESM (collective fault signal/individual fault signal) in twin-head pump operation:
–
The SSM function must preferably be connected to the main pump. The SSM contact can be con-
figured as follows:
the contact reacts either only in the event of a fault or in the event of a fault and a warning.
Factory setting SSM only reacts in the event of a fault.
Alternatively or additionally, the SSM function can also be activated on the standby pump. Both con-
tacts work in parallel.
–
ESM: The ESM function of the twin-head pump can be configured on each head of the twin-head
pump head as follows: The ESM function on the SSM contact only signals faults of the respective pump
(individual fault signal). In order to record all faults of the two pumps, both contacts must be assigned.
11.2 Application and function of SBM relay
The contact of the collective run signal (SBM, potential-free normally open contact) can be connected to a
building automation system. The SBM contact signals the operating status of the pump. The SBM relay can
either switch on for "Motor in operation", "Ready for operation" or for "Power supply ready".
• When the pump is running in the set operating mode and based on the next settings, the contact between
the terminals COM (85) and RUN (88) are closed.
In the "Settings" menu
1. "External interfaces"
2. "SBM relay function".
