2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
Issue 10 July 2000
Product Description 2 - 9
LEDs
The control panel on the J85503C-3 has the following LEDs:
PHA: A red LED lights if the rectifier shuts down due to phase voltages
falling below the normal operating range or total loss of a phase
FA: A red LED lights if any fuse, except the LSF fuse, operates or the
output circuit breaker operates
RFA: A red LED lights if a failure occurs in the rectifier and the rectifier
shuts down
LSF: A yellow LED lights if the fuse in the load share circuit of the
rectifier operates
LCA: A yellow LED lights if the load share option is active and the
rectifier is providing less than 3 amperes of output current. The LED
remains on until output reaches 12 amperes
ACF: A red LED lights if the three-phase commercial ac into the
rectifier fails and the rectifier is connected on battery.
Rect Test Switch
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. If the load share is not enabled,
the rectifier goes to maximum current (FL) or no current (NL). If load
share is enabled, the Rect Test switch provides no significant function.
Rect + and - Test
Jacks
The Rect + and - test jacks allow for measuring the output voltage of the
rectifier.
Plant + and - Test
Jacks
The Plant + and - test jacks measure the voltage between the points
where the remote sense leads are connected. This measurement is
accurate only when the remote sense leads are connected.
Float Adj
The Float Adj potentiometer provides for manual adjustment of the
output float voltage.
