Metering Chapter 5
Power Factor
Power Factor is calculated for each phase along with a total power factor value.
The power factor calculation does not apply during Braking operations.
Table 30 - Metering Parameters Associated with Power Factor
Elapsed Time
The SMC-50 control module keeps a log of the total accumulated hours the
controlled motor has been running via the Elapsed Time metering parameter.
The Elapsed Time meter value is updated every 10 minutes and stored at power
down (accurate to 1/6 of an hour). The Elapsed Time meter accumulates to
50,000 hours of operation and can be reset to zero via the Meter Reset parameter
(see Resetting Metering Parameters
on page 122).
Elapsed Time 2 is similar to Elapsed Time. Elapsed Time 2 differs in that you
cannot reset it and will count up to 50,000 hours and then hold that value (it will
not roll over).
