FANUC Alarm PNT2-632 — %s0 air flow rate timeout

FANUC PNT2-632 (“%s0 air flow rate timeout”): All of the conditions were set for air to be flowing and a zero flow rate was measured for longer than the Zero flow timeout parameter. First check: Check, clean and possibly replace the air cap. Likely part: Air flow sensor (Air flow sensor) +1 more.

Description

All of the conditions were set for air to be flowing and a zero flow rate was measured for longer than the Zero flow timeout parameter. This may be caused by: a clogged air cap, a broken applicator trigger, broken air lines, a loss of air supply pressure, a broken air flow sensor, a broken cable (to the flow sensor), or a Zero flow timeout value 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 broken air line. Possibly increase the Zero flow timeout parameter (by about 25%).
