2.3.1 Auxiliary connector socket
An auxiliary control connection on the rear panel controls an optional inlet
valve. This inlet valve can be operated in parallel with the normal pump
output signal. Refer to Figure: General view, (7). The valve is usually closed
and:
▪ 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 Figure: Valve connector for the 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.
