FANUC Alarm PAIN-452 — WARN %sMax. flow below mid point

FANUC PAIN-452 (“WARN %sMax. flow below mid point”): This alarm occurs only during calibration. First check: Increase the fluid pressure.

Updated 2026-08-29 · LogrobotLM reference

Description

This alarm occurs only during calibration. The flowrate measured at the maximum control and one half of the maximum control output was nearly the same. Less than one half of the control output range is useable. The system may still function even though this alarm has occurred. This may be d by low fluid pressure, a faulty transducer or regulator or the wrong I/P transducer being installed (100 psi range instead of 50 psi range).

Remedy · Remède

Increase the fluid pressure. Check that the transducer is functioning properly and that it is has the correct pressure range, change it if appropriate. The system may operate, but performance can be improved with one of the above remedies.
