FANUC Alarm PNT1-654 — %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 caused 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.
