• The inner metal panel can now be carefully set into place and secured
using the eight (8) #8-18 x 1/2" mounting screws provided. Two (2) #8
speed clips are provided to replace any missing or damaged.
WARNING! Never connect (turn on) power with inner metal panel removed.
• Connect (turn on) the power supply to the Strand DE90 dimmer rack.
• Verify the operation of the system status LED indicators, LCD display
and programming switches. Refer to page 18 to 20 for details.
• Refer to the programming section of this manual for system
configuration. Refer to page 22 to 37 for details.
• Test the system thoroughly to ensure all wiring terminations are
functioning.
• 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 DE90-3000
Series retrofit systems is for three-phase applications. The defaults
(DEFAULTS) menu is used to reconfigure the phase patch for standard
single-phase applications and the phase patch (Ø-PATCH) menu is
used to configure non-standard applications. Refer to page 31 and 36
for programming details. Refer to the charts on page 8 for the standard
dimmer to phase patch configuration for DE90 dimmer racks.
• Verify all dimmers are controlled sequentially. The Dimmer to Channel
Patch (DC-PATCH) will need to be modified (programmed) to
compensate for a mixture of single, dual and quad dimmer modules.
Refer to page 27 for programming details. Examples of DC-PATCH
configurations can be found on page 9 and 10. Charts used to
determine the DC-PATCH can be found on page 11 and 12.
• Verify fan operation. The fans are triggered on at 6% DMX input control,
and stay on as long as the DMX is at 6% or greater. When the DMX
input is brought down below 6%, there is a 5 minute timeout for the fans
to turn off. When the Panic Switch is turned on the fans turn on; when
the Panic Switch is turned off the fans turn off.
• Verify Front Panel (Faceplate) Panic Switch operation. When the Panic
Switch is turned on, all of the dimmer outputs are full-on.
• Verify Front Panel (Faceplate) DMX-B Input operation. The DMX B
LED will illuminate and the LCD will show the number of DMX channels
received.
• Once the DE90-3000 retrofit system has been thoroughly tested the
dimmer rack door can be carefully set back on the hinges and closed.
