FANUC Alarm PAIN-438 — WARN %sCal. time out at max. flow

FANUC PAIN-438 (“WARN %sCal. time out at max. flow”): Accuflow timed out trying to reach the maximum flow rate. First check: Possibly decrease the Gain modifier used for the color. Likely part: Fluid regulator (Fluid regulator).

Updated 2026-08-29 · LogrobotLM reference

Description

Accuflow timed out trying to reach the maximum flow rate. Possible s are: a high gain, a sticking I/P transducer, a bad fluid regulator or frequent fluid pressure changes.

Remedy · Remède

Possibly decrease the Gain modifier used for the color. Retry the calibration. Check and change the transducer if necessary , replace the fluid regulator or service the surge suppression system on the fluid supply pump. The calibration timeout parameter can be increased.
