Item Name Description
1
Main Air Regulator
and Gauge
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
6.5 Adjusting the Air Pressure
for the recommended pressure settings and other important information.
2 Rear EMO
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.
3 Main Circuit Breaker
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.
4 Main Power Cord
The Main Power Cord connects the dispensing system to the facility
power supply.

6 Water Trap
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.
