2.4 Logic interface
The logic interface is designed to support the two connectors, both are
located on the rear of the pump.
▪ Serial control is connected through a X104 SUB-D 9 pin (female)
connector.
▪ Parallel control is connected through a X1 SUB-D 9 pin (male)
connector.
The signals on the logic interface are:
▪ control inputs: switch type and analogue signals that control the pump.
▪ status outputs: to identify the status of the system tab.
For control modes refer to Table: Control panel interface.
For logic interface data refer to Logic interface data on page 26.
2.5 Gauge connection
A compatible pressure gauge can be connected to the RJ45 (X101) socket
on the rear panel. Refer to Accessories on page 56, for suitable gauges.
