2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
Issue 10 July 2000
Product Description 2 - 13
CM2 (208F
Control Board)
The CM2 circuit module (208F Control Board) contains the following
circuits:
CM3 (323D Digital
Meter Board)
The CM3 circuit module (323D Digital Meter Board) controls the
digital Output meter and all indicators on the rectifier control panel.
The meter displays the rectifier’s output current, voltage, or the plant
battery voltage, depending on the position of the selector switch. See
Figure 2-1.
CM4 (330B
Interface Board)
The CM4 circuit module (330B Interface Board) provides alarm and
control circuitry that permits the rectifier to interface with various
controllers. It also provides additional monitoring points and new alarm
interface points for AC fail, RFA test, load share, LCA, and LSF.
CM5/CM6
(ED83156-30 G3)
The CM5 and CM6 circuit modules are identical boards, ED83156-30
Group 3. These boards contain a triac/thyristor snubber network and
EMI circuitry. Refer to schematic drawing SD82685-02 for further
information.
CM7 (425C/D/E/F
Transformer
Boards)
The CM7 circuit modules (425C/D/E/F Transformer Boards) contain
the sense transformer, bleeder resistors, and walk-in reset relay.
Warning: Circuit modules must not be connected or disconnected
with voltages present. Personal injury or equipment damage may
occur. See Section 8 for how to replace circuit modules.
