6.4 Fault Finding Guide
FAULT SYMPTOM
POSSIBLE CAUSE
REMEDY
Breaker trips
Excessive load
Reduce channel loading
Lamp or wiring fault
Check lamps and wiring
Poor ventilation
Increase air flow to HPC side vents
Faulty HPC
Service HPC
One channel flickers when dimmed
DMX source problem
Softpatch another console fader
Service console
Faulty HPC channel
Service HPC
Same load flickers on other channel
Insufficient or very inductive load
Connect >100W incandescent lamp
in parallel
NE Error on display
Poor Earth or Neutral connection
Check supply wiring. Disable N-E
detector in menu (6.3)
All Channels flicker when dimmed
Incorrect DMX protocol / wiring
Replace DMX source / wiring
Un-terminated DMX line
Activate Terminate facility on the
last HPC (5.1.4)
Mains control tones exceed limits
Contact factory
Signal LED flickers
Faulty DMX wiring/connections
Repair
Faulty console
Repair
Faulty HPC
Service HPC
RDM doesn’t work at all
Controller has RDM disabled or not
configured correctly
Reconfigure controller
Controller does not conform to the
published RDM standard
Check specification for the
controller version of RDM
HPC RDM source not correctly set
Change source setting (5.1.5)
Intermediate equipment (eg DMX splitter)
not RDM compatible
Check specs of all other equipment
RDM operation erratic
DMX line un-terminated
Terminate the DMX line
Poor DMX wiring
Replace DMX wiring
Specific RDM feature doesn’t work
Feature not supported by either HPC or
Controller
Check specs for supported
commands (9.2)
Channel/s don’t respond to DMX
Channels set to On or Off
Change channel mode (4.3.1)
Level source incorrectly set
Change source setting (5.1.5)
Error LED flashing
Over-temperature
Improve HPC ventilation
Error LED on continuously
Recent over-temperature
Improve HPC ventilation
DMX control errors
Check DMX wiring, console
HPC memory corrupt
Deep Clear HPC
Software failure
Service HPC
No signal at DMX Loop output
Terminate facility active
De-activate Terminate facility
Channels wont drive to full
CAP function enabled
Change CAP Setting in menu
HPC very hot
Increase air flow to HPC vents
All channels glow
Preheat set too high
Reduce preheat level
HPC shuts down
HPC very hot
Increase air flow to HPC vents
