5. Double pump [91] [92]
The pumps are designed for single operation in systems
with increased safety requirements (pump 1 or pump 2).
The switching over of the pumps is dependent on time
or when the pump fails.
The pumps work with an operating duration of 22 hours
for the main pump and 2 hours for the reserve pump.
If both pumps are configured as a master,
22h/2h operating is possible.
The main pump or reserve pump
is configured using the button (1).
LED (2) flashes, main pump (master/22 hours)
LED (3) flashes, reserve pump (slave/2 hours)
Connection: clamps 91 and 92
Installation: connect both pumps together
via a two-core cable (maximum 2 m).
Maximum cable cross-section, 1mm
In the passive operating mode the motor stands still
