FANUC Alarm PNT2-625 — Min. output has flow > setpoint

Manufacturer wording — %sMin. output has flow > setpoint
The manual prints placeholders; your controller fills them in with the real group, axis or number.

FANUC PNT2-625 (“Min. output has flow > setpoint”): With a minimum control output, the flow rate was measured to be higher than the setpoint (requested flow). First check: Check and repair the various air lines.

Description

With a minimum control output, the flow rate was measured to be higher than the setpoint (requested flow). The Max. control out (ms) parameter affects the sensitivity of this alarm. This might be caused by a leaking or broken air line between the flow sensor and the applicator. The I/P transducer might be stuck open. The air booster might be stuck open or leaking. This might be caused by a faulty air flow sensor (reading more flow than there really is). Note, AccuAir temporarily automatically changes to Open Loop when this alarm occurs.

Remedy

Check and repair the various air lines. Check and repair the air booster. Check and repair the I/P transducer. Possibly increase the Max. control out (ms) parameter.
