FREQUENTLY ASKED QUESTIONS
Listed below are a few answers to common questions.
1. NO POWER TO THE PACK
Disconnect the power cord and reconnect to ensure there is a proper connection. If the problem still
persists, check the venue/building electrical service panel for any circuit breakers that are tripped/off.
2. NO CHANNEL OUTPUT
Check the device power cords connected to the pack are properly inserted into the channel outlets
and each device power switch (if used) is powered ON. If the problem still persists, check the
internal fuses. (see Fuse Replacement instructions below)
3. NO DMX CONTROL
Check the 3pin DMX IN/OUT cable connections to the pack are properly attached and the cables
are not damaged. If problem still persists, check the DMX Controller is connected and powered On,
and it is sending the correct DMX values. (see DMX traits on page 14), Check the correct DMX
address is assigned to the pack. (see DMX Address settings on page 12)
4. NO OUTPUT IN PROGRAM MODE
Check Dimmer mode for each Channel setting. If Dimmer mode is set to 000 then none of the
connected lights will turn on because 000 is blackout. Set the Dimmer mode for each channel to a
desired Dimmer setting higher than 000. (see page 15 for Dimmer settings)
FUSE REPLACEMENT
Disconnect the power cord. Check the corresponding channel fuse or fuses by removing the four
phillips head screws on the rear panel to expose the circuit board and fuses. Each channel fuse is
marked on the PCB- TH1 = Channel 1, TH2 = Channel 2, TH3 = Channel 3 and Th4 = Channel 4.
Check the relevant channel fuse or fuses and replace if required. The DP-415 incorporates four 6.3A
250V normal blow fuses. Replace rear panel and phillips head screws.
