FANUC Alarm PAIN-451 — WARN %s0 fluid flow rate timeout

Description

All of the conditions were set for fluid to be flowing and a zero flow rate was measured for longer than the Zero flow timeout parameter. This may be d by: a broken applicator trigger, a loss of fluid supply pressure, a broken fluid flow meter, a broken cable (to the flow meter), or a Zero flow timeout value that is too short. Note, AccuFlow temporarily automatically changes to Open Loop when this alarm occurs.

Remedy · Remède

Check that the gun is properly triggering. If fluid was observed to be flowing, check and possibly replace the fluid flow meter. Possibly increase the Zero flow timeout parameter (by about 25%).
