ƒ
SSM: The SSM function must preferably be connected to the main pump.
The SSM contact can be configured 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 contacts work in parallel.
ƒ
ESM: The ESM function of the twin-head pump can be configured on each 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 detect all faults of the two pumps, the contacts
must be assigned in both drives.

These submenus appear only when the twin-head pump is connected and depending
on the selection of SSM or SBM.
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.
ƒ
The SBM contact can be assigned to any of the two pumps. The following config-
uration is possible:
The contact is activated when the motor is in operation, power supply is present
(network-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.
To do this, select the following in the menu:
