2000 125A Ferroresonant Rectifier J85502C-1
Issue 8 July 1999
Product Description 2 - 7
The 434B board is the same as the 434A except when the ac
circuit is activated, it also issues a MAN alarm.
Front Panel
Controls and
Indicators
Figure 2-1 shows the control panel on front of the J85502C-1,
125-ampere rectifier. The following list describes the controls
and indicators on the control panel. These features should be
observed and manually operated during normal rectifier
performance. Bold letters indicate labels that appear on the
control panel or inside the rectifier.

The digital output meter displays (1) the rectifier output
current when the selector switch is in the AMPS position,
(2) the rectifier output voltage when the selector switch is in
the RECT V position, and (3) the plant battery voltage
when the selector switch is in the BATT V position. The
default display is rectifier output current. Table 2-A gives
the accuracy of this meter in the various positions. The
output voltage (RECT V) accuracy depends on the vintage
of the digital meter board, or circuit module CM3, in the
rectifier.
Caution
Circuit modules must not be connected or disconnected
with voltages present or equipment damage may occur.
See the following topics in Section 8: “Replacing Circuit
Modules” for how to replace circuit modules and
“Handling Circuit Modules” for proper handling of circuit
modules to avoid damage from electrostatic discharge.
