• If the DMX input is connected internally, on a terminal block mounted
inside the CD80 dimmer pack, jumpers will need to be moved on the
DPC-24/12 circuit board to enable the DMX-B input. To enable the internal
DMX through the EDGE2 connector on the DPC-24/12 circuit board, move
the three (3) jumpers on JP2 to the left-hand side position. To enable the
internal DMX through the EDGE3 connector on the DPC-24/12 circuit
board, move the three (3) jumpers on JP3 to the left-hand side position.
• Line up the DPC-12 or DPC-24 control module with the guide rails on each
end of the control module slot.
• Carefully slide the DPC-12 or DPC-24 control module in until the
connectors on the DPC-24/12 circuit board touch the rear connectors
inside the CD80 dimmer pack.
• Line up the two (2) thumbscrews on the DPC-12 or DPC-24 with the
mounting holes on the CD80 dimmer pack.
• Firmly push the DPC-12 or DPC-24 in on both ends until the control
module is fully seated.
NOTE: If it feels like the control module isn’t fully seated or doesn’t slide in
easily, it may be necessary to re-align the rear connectors inside
the CD80 dimmer pack to their upper most position, due to the
inconsistencies in the assembly of the CD80 dimmer pack. This can
be accomplished by loosening the two (2) mounting screws on each
end of the rear connectors by half a turn, sliding the connectors up as
much as possible and then re-tightening the mounting screws.
• Tighten the two (2) thumbscrews to secure the DPC-12 or DPC-24 in the
CD80 dimmer pack.
Turn on and test the new DPC-12 or DPC-24 retrofit control
module
• Connect (turn on) the power supply to the to the CD80 dimmer pack.
• Verify the operation of the system status LED indicators, LCD display and
programming switches.
• Refer to the programming section of this manual for system configuration.
• Test the system thoroughly to ensure everything is functioning properly.
• Verify all of the dimmer control outputs have the correct phase referencing.
If a dimmer control output is patched to the incorrect phase reference, the
dimmer will not dim correctly and will go to full output at around 1% DMX
input. The factory configuration for DPC-12 and DPC-24 control modules
is for standard three-phase applications, with the dimmer phase reference
patch set at AAAABBBBCCCC… For standard single-phase applications,
set the default (DEFAULT) menu for single-phase (1ØPATCH) operation,
with the dimmer phase reference patch set at AAAAAAAACCCCCCCC…
The phase patch (Ø-PATCH) menu must be used to configure non-
standard applications.
• Verify the fan inside the CD80 dimmer pack is operating properly. The fan
should turn on with between 6-7% DMX (or other) control – when DMX (or
other) control drops below 6-7%, there is a 5 minute timeout on the fan to
ensure the dimmers have been cooled sufficiently. If required, replacement
fans are available (Johnson System Inc., Part Number: CF-CD80P).
