Instruction Manual

3-4 Component Description
When the Keyswitch is in the OFF (0) position, the yellow Beacon light is ON and the Interlock Recovery
Light is ON. Opening the Dispensing Area Doors in this state does not disable the dispensing system
motion controls.
The Interlock Key can be removed to prevent an inadvertent mode change. See 2.10 Integrated Safety
Systems for additional information.
CAUTION! Do NOT use the Interlock OFF mode during normal operation. Use the OFF
mode only when servicing or programming the dispensing system.
3.7.7 Light Beacon
The Light Beacon is a device that displays system status and is located at the top right corner of the
system. It has four different colored lights that can be constantly ON or flashing and has an audible alarm.
Refer to 2.10.4 Light Beacon for an explanation of each color indication.
3.7.8 Low Air Pressure Sensor
The Low Air Pressure Sensor is connected to the Main Air Inlet. If the pressure drops below a set point, it
triggers the dispensing system Safety Interlock. This feature is used to alert the operator of pressure drop
conditions that may occur in large facilities with a number of pneumatic devices.
3.7.9 Exhaust Vent Duct
The Exhaust Vent Duct (Figure 1-6) removes fumes from the dispensing area. A customer supplied air
duct must be connected from the dispensing system to the facility air exhaust system for the system to
operate. Refer to 4.11 Exhaust Connection.
