Introduction

Main Air Regulator and Gauge Sets (Close-up)

The system is equipped with two Main Air Regulators and Gauges. They

control the air pressure supplied to all other system regulators. The

regulators contain built-in air filter and water traps to ensure that only

clean, dry air enters the system. Refer to

for the recommended pressure settings and other important information.

The Rear EMO is a built-in safety feature located on the rear panel of the

dispensing system. Activating the EMO vents all pressure in the

pneumatic system, de-energizes the servo power, and cuts power to all

system components except the computer.

The Main Circuit Breaker is the main power switch for the dispensing

system. It protects the dispensing system from facility power surges and

controls the flow of facility AC power supplied to the Power Manager. A

flange to the right of the Main Circuit Breaker allows it to be locked in the

OFF position during servicing. Switching OFF the Main Circuit Breaker

cuts power to all dispensing system electrical components.

The Main Power Cord connects the dispensing system to the facility

power supply.

The facility air supply may contain moisture that can damage the

dispensing system. The Water Trap condenses this moisture before it

enters the dispenser pneumatic system.
