FANUC Alarm PAIN-541 — WARN %sLower output did not lower flow

Description

As the AccuAir calibration steps down through the 10 points in the calibration table, it expects a lower flow for each decrease in the command flow value. In this case the flow did not decrease. This can be d by insufficient exhaust, no quick exhaust on the pilot air line, too large of a hysteresis in control equipment, or the system response is too slow for the current setting of the Calibration step delay parameter.

Remedy · Remède

Retry the calibration. Check that the pilot air line to the booster has sufficient exhaust capability. Increase the Calibration step delay parameter (by about 100%). Reducing the Leveling tries parameter may help.
