2000 100A Ferroresonant Rectifier J85503A-1
Issue 6 October 1998
Product Description 2 - 11
•
The Power (Control) switch turns the rectifier on and off.
When the switch is in the Off position, the rectifier cannot
be turned on by the plant controller. When in the On
position, an MCS controller can remotely turn the rectifier
on or off to satisfy the plant load current requirements. The
Power On LED emits a green light to indicate that the
rectifier is on.
•
The Phase Alarm (PHA) LED emits a red light when any
one or more of the three ac input phase voltages decreases
approximately 35 percent from the nominal value. If the
voltage on any phase is completely missing, a phase alarm
issues and the rectifier shuts down. If the load is light, the
rectifier may stay on.
•
The Rectifier Failure Alarm (RFA) LED lights and a signal
is sent to the plant controller if the rectifier fails because of
external or internal high voltages, a blown fuse, or an
internal unbalance.
•
The Rect Test switch provides a manual test of the rectifier
regulation by simulating a full load (FL) or no load (NL)
condition. Operating the switch raises or lowers the output
voltage setting of the rectifier by 0.25 volt when on battery.
When the switch is in the center position, the rectifier is in
the normal operating state.
•
The Output Volts Adj potentiometer provides for manual
adjustment of the output float voltage.
