FANUC Alarm PAIN-283 — WARN %sMin. output has flow > setpoint

FANUC PAIN-283 (“WARN %sMin. output has flow > setpoint”): With a minimum control output the flow rate was measured to be higher than the setpoint (requested flow). First check: Calibrating the color will establish a new cracking pressure (minimum control output) for a changed fluid pressure. Likely part: Transducer (Transducer) +1 more.

Description

With a minimum control output the flow rate was measured to be higher than the setpoint (requested flow). The fluid pressure may have become too high. The I/P transducer or fluid regulator may be stuck open. There may be a fairly large fluid leak. Note, Accuflow automatically changes to Open Loop when this failure occurs.

Remedy · Remède

Calibrating the color will establish a new cracking pressure (minimum control output) for a changed fluid pressure. Check and replace if necessary the fluid regulator and I/P transducer. See the Fluid flow leak alarms for other options.
