Graco 332564B System Errors, To Clear Error and Restart, Gun Trigger Input Function

System Errors

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 89).

•Status bar on the Advanced Display Module shows the active alarm code.

•Alarm is saved in the date/time stamped log.

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 65, 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. Users also may acknowledge and clear errors via a network device. INPUT REGISTER 08: Clear Active Alarm in ProMix PD2K Network Inputs, page 36.

Gun Trigger Input Function

The Gun Trigger Input signals the controller when the gun is triggered. The gun icon on the Advanced Display Module shows spray when the Gun Trigger Input 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 Gun Trigger Input is so important.

If the unit detects through the Gun Trigger Input 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.
