sustained high load or in fault conditions.
The pump controller has the interface control panel and the pump can be operated:
▪ manually, with the buttons on the user interface control panel. Refer to Figure:
Interface control panel .
▪ remotely, through serial communications or digital and analogue process control
(parallel), via the 15-way D-type interface connector. Refer to Connection for
remote control and monitoring on page 24.
