Troubleshooting and Fault Recovery
The following table describes the valid fault codes
used by the PrecisionFlo module, possible causes, and
solutions. See Theory of Operation – Fault Han-
dling on page 58 for detailed information on how fault
codes are communicated.
The PrecisionFlo module displays warnings and
alarms on the control pendent’s screen.
Warnings do not stop the module from dis-
pensing.
Alarms stop the module from dispensing.
Warnings are listed in Table 6, Alarms are listed in
Table 7.
Restarting the Module After a Fault
If a fault has occurred, you must clear the fault before
restarting the PrecisionFlo module.
1. Press
[F1]
on the control pendant to clear the
fault.
2. Press MASTER START/STOP RESET, (24) in
Fig. 30, on the control assembly. This turns on
power to the PrecisionFlo metering valve drive
circuitry and lights the CONTROL ON indicator.
