faults of the respective pump (individual fault signal). In order to record all faults
of the two pumps, both contacts must be assigned.

SBM/EBM (collective run signal/individual run signal)
–
The SBM contact can be assigned to any of the two pumps. The following con-
figuration is possible:
the contact is activated when the motor is in operation, power supply is present
or no fault is present.
Factory setting ready for operation. Both contacts signal the operating status of
the twin-head pump in parallel (collective run signal).
–
EBM The EBM function of the twin-head pump can be configured as follows:
the SBM contacts only signal run signals of the respective pump (individual run
signal). In order to record run signals of both the pumps, both contacts must be
assigned.
ƒ
Communication between pumps
Communication for a twin-head pump has been set at the factory.
Wilo Net must be installed with cable between the pumps when connecting two
single pumps of the same type to a twin-head pump.
Then set the termination as well as the Wilo Net address in the menu under “Set-
tings/external interfaces/Wilo Net setting”. Then configure the settings “Connect-
ing twin-head pump” in the “Settings” menu, sub-menu “Twin-head pump opera-
tion”.
NOTICE
For the installation of two single pumps to form a twin-head pump, see sections
“Twin-head pump installation/Y-pipe installation” [
} 163], “Electrical connec-
tion” [ } 165] and “Application and function of the Wilo Net interface” [ } 232].
12.2 Twin-head pump behaviour
The control of both pumps starts from the main pump to which the differential pressure
sensor is connected.
In case of breakdown/fault/communication interruption , the main pump alone takes
over complete operation. The main pump runs as a single pump according to the set
operating modes of the twin-head pump.
The standby pump, which receives no data from the differential pressure sensor, runs in
the following cases at an adjustable constant emergency operation speed.
ƒ
The main pump to which the differential pressure sensor is connected fails.
ƒ
The communication between the main pump and the standby pump is interrupted.
The standby pump starts immediately after detecting a fault.
