GETTING STARTED
The COMMANDER 320 Booster Pump Controller acts as a differential pressure switch for use
in the regeneration section of a pasteurizer. If the difference between pasteurized milk
pressure and raw milk pressure falls below a preset level, the controller shuts down the raw
milk booster pump or alternatively, channels the pasteurized milk into the divert flow.
The COMMANDER 320 has the following features:
•
Two 4 to 20mA analog inputs.
•
A transmitter power supply capable of powering the raw and pasteurized 2-wire
pressure transmitters.
•
A digital display of the raw and pasteurized product pressures.
•
A bargraph display of the difference between the raw and pasteurized pressures.
•
A deviation alarm to detect when the difference between the raw and pasteurized
pressures falls below a preset minimum.
•
A start-up alarm which allows the booster pump to remain off until the normal system
operating back pressure is achieved.
•
A manual override facility which allows the booster pump to be turned off using a digital input.
•
Selectable pressure differential retransmission output.
•
Three relay outputs: two for booster pump or divert valve control, one to operate a
warning light or horn.
This manual is divided into 4 sections and contains all the information necessary to install,
configure and operate the instrument.
