Check the Power Factor Indicator and Reset Button
The front panel of BPSU672A provides a Power Factor LED and Reset button. If the cabinet power
factor is exceeded by overload of PCBs, the PF LED will turn on.
➤
If the PF LED indicator turns on, press the PF reset button with a pointed tool or pencil. If the PF
LED turns off and does not turn on again it may have been turned on by a current surge while
installing a PCB while the power supply was turned-on.
➤
When a PF alarm is indicated, check that the cabinet power factor is not exceeded using the
“System Power Factor Check Considerations” on Page 1-27
. If the Power factor has been
exceeded relocate any PCBs that are causing the PF to be exceeded.
