will open when the normal signal becomes active (pump at speed)
▪
will close when you select the stop button or if there is a fault condition
The reaction time will be in line with the valve selection and the output signal is 24 V d.c.
Refer to
for polarity of the connector pins when the connector is
energized.
The auxiliary connector is regulated to 24 V d.c. to control the accessories. If the
auxiliary load current exceeds the value in
Table: Auxiliary load currents
, the output will
shut down to protect the pump controller. Refer to
Table: Recommended mating plugs
for the recommended mating plugs.
