System Errors - Graco ProMix PD2K Electronic Operation

System Errors

System errors alert you of a problem and help
prevent off-ratio spraying. There are three types:
Advisory, Deviation, and Alarm.
An Advisory records an event in the system, and will
clear itself after 60 seconds.
A Deviation records an error in the system but does
not shut down the equipment. The deviation must be
acknowledged by the user.
If an Alarm occurs, operation stops.
If any of the three types occur:
• Alarm buzzer sounds (unless in silent mode).
• Alarm popup screen shows the active alarm code
(see Error Codes, page
• Status bar on the Advanced Display Module shows
the active alarm code.
• Alarm is saved in the date/time stamped log.

62).
To Clear Error and Restart
NOTE: When a deviation or alarm occurs, be
sure to determine the error code before resetting
it. If you forget which code occurred, go to the
Errors Screen, page 37, to view the last 200 errors,
with date and time stamps.
If an alarm has occurred, correct the cause before
resuming operation.
To acknowledge a deviation or clear an alarm, press
on the Advanced Display Module or
on the Booth Control.
Air Flow Switch (AFS) Function
The air flow switch (AFS) detects air flow to the gun
and signals the controller when the gun is triggered.
The gun icon on the Advanced Display Module shows
spray when the AFS is activated.
If a pump fails, pure resin or catalyst could spray
indefinitely if the unit does not detect the condition
and intervene, which is why the AFS is so important.
If the unit detects through the AFS signal that the gun
is triggered, yet one or both of the pumps are not
running, a Flow Not Detected Alarm (F8D1) occurs
after 10 seconds (default) and the system goes into
Standby.
