FANUC Alarm PNT2-746 — %sPump 1 totals differ > tolerance

Description

The actual total flow out of pump #1 as measured by the fluid flow meter has a value that is different than the commanded total flow. This difference is larger than the total flow tolerance.

Remedy · Remède

Do a fluid flow test on pump #1 with a beaker and verify that the beaker amount matches the pump #1 size (cc/rev). Verify that the correct KFT factor has been entered for the fluid flow meter per the manufacturers specification. Check the operation of the inlet regulator to verify that no (blow by) is occurring across the pump. Verify that pump #1 does not have excessive wear.
