Feedwater Pump RotationFILED UNDER: PI PWC
User can confuse what the hours display.
They may think the hours should display more than 3 digits.
They may think the run hours are not working.
Steps to Troubleshoot
None...this is how it is supposed to work (see below).
See the attached screen. Each pump has run hours...but they are only the hours the pump has run as the lead.
If a pump is running as a lag pump, its hours will not accumulate.
So the "Lead Rotate Every XXX Hours" means the lead pump must run XXX hours before an automatic lead change will take place.
NOTE: The maximum value is 744 hours (equals one week continuous.).
