Symptom Remedy
The unit does not work, no light,
the display is dark
Check the mains connection and the main fuse.
Apparently no function despite
proper power supply
Check if the unit is in DMX mode or in ‘slave’ mode. If so,
check the unit in another mode.
No response to the DMX con‐
troller
1. If the unit is in DMX mode and the display flashes, no
DMX signal is received. Check whether the DMX con‐
troller is switched on. Check the DMX connectors and
cables for proper connection.
2. If the unit is in DMX mode and a DMX controller is
connected and turned on, a dot on the fourth digit of
the display will flash. If it doesn't, no valid DMX signal is
received. Check whether the DMX controller is switched
on. Check the DMX connectors and cables for proper
connection.
3. If the display dot is flashing but there is still no
response, check the address settings and the DMX
polarity.
