On-Board System Status Indicators
The dispensing system employs on-board Light Emitting Diodes (LEDs), a Light Beacon, and
FmNT/firmware error messages to indicate system status.
LEDs
An illuminated or non-illuminated status LED has a specific significance. The function of the LEDs is to
indicate the operational readiness of the system or its components. Observing the LEDs is key to the
troubleshooting effort. Note that a few LEDs can change so frequently that they may not appear to change
state. Although unlikely, the LED itself may be malfunctioning, giving a false condition report.
Light Beacon
A color coded and illuminated or flashing light on the Light Beacon signals irregularities in the
dispensing system operations for the operator. These signals can be of benefit for the service technician as
well during the troubleshooting effort as a conformation factor during the fault elimination and isolation
process.
FmNT Error Messages
Note any FmNT error messages. They may be useful in determining where to start troubleshooting. An
FmNT error message indicates a desired function of the system cannot successfully be accomplished. The
remedy in most cases consists of selecting options on the screen. In other cases, it may be the result of a
communications problem. Overriding error messages as a means of recovery can result in improper
system operation.
Facility Corrections
Incorrect facility voltage, air pressure supply, ventilation, or uneven floors can adversely affect system
performance. Facility requirements are specified in the Introduction section of this manual.
WARNING! Failure to provide the required facility electrical power, pneumatic power, and
environmental conditions may cause damage to the system and may void the
warranty of the system or replacement parts.
Problems from incorrect system installation after relocation should be corrected before undertaking the
troubleshooting procedures listed in this section.
Problems resulting from environmental and applications abnormalities, spills, obstructions, and
workpiece irregularities not related to the system should be eliminated before starting advanced
system troubleshooting.
