FANUC Alarm PNT2-622 — %s0 air flow rate detected

Description

All of the conditions were set for air to be flowing and a zero flow rate was measured. This might be caused by: a broken applicator trigger, pinched air lines, a loss (or near loss) of air supply pressure, a broken air flow sensor, a broken cable (to the flow sensor), or a Trigger delay that is too short. Note, AccuAir temporarily automatically changes to Open Loop when this alarm occurs.

Remedy · Remède

Check, clean and possibly replace the air cap. Check that the gun is properly triggering. If air was observed to be flowing check and possibly replace the air flow sensor. Check for a pinched air line. Increase the Trigger delay parameter (by about 50%).
