FANUC Alarm PNT2-769 — (%s) Zero PSI

FANUC PNT2-769 (“(%s) Zero PSI”): The IPC auto calibration aborted because zero PSI was detected while the IPC system was determining the maximum flow rate during the auto calibration or while the IPC system was determining one of the calibration points. First check: Ensure pumps are operating correctly.

Description

The IPC auto calibration aborted because zero PSI was detected while the IPC system was determining the maximum flow rate during the auto calibration or while the IPC system was determining one of the calibration points.

Remedy · Remède

Ensure pumps are operating correctly. Ensure that the speed command delay (used to allow the motor RPM to settle) is set to a sufficient amount. If the setup parameter, Max speed cap:, was enabled, ensure that the parameter User speed cap:, was not set to high - the pressure will eventually plateau at higher speed commands. Alternate action is to disable Max speed cap: and re-calibrate.
