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.

2.4 Security Access – Figs 2.1 and 2.2
A security system is used to prevent tampering with the program parameters by utilizing a
security input together with an Alarm password and a Configuration password – see Figs. 2.1
and 2.2. Two levels of security are provided:
a) Security input secure – Alarm and configuration settings cannot be accessed.
The security input may be protected by a tamper-proof seal – see Fig.2.3
b) Security input insecure – Alarm and configuration settings can be accessed by use of
the correct password.
