Introduction
Safety Notes
318
DO NOT:
• Use in an environment where moisture or flammable vapor might come in contact with the unit.
• Insert or remove flash heads without first switching off.
• Restrict air vents while in use.
• Use a unit with damaged housing, moldings, flash tube or modelling lamp.
If the unit is dropped or damaged in any way, always have it checked out before using.
• Operate the unit without a safe grounded (earthed) AC supply.
DO:
• Switch power off and disconnect from the supply before changing modelling bulb or flash tube.
• Excercise care when handling equipment that has been in use. The reflector and front end of
the flash head can become Very Hot.
• Observe the mains supply requirements.
• Avoid placing cables where they can be tripped over. Protect from heavy, sharp or hot objects,
which may cause damage and replace damaged cables immediately.
• Due to the high voltage / high energy used in QUADX Units, all servicing must be carried out
by an authorised Service Centre.
• Remove the power cord by gripping the plug. NEVER pull the cord.
• Ensure that any extension cord used has a suitable current rating to prevent overheating and
never use coiled extension cords.
• ALWAYS remove the flash head covers before using.

WARNINGS & FAULT FINDING
If the unit appears to have developed a fault, first establish that it is a genuine internal fault and not a
case of normal operation such as overheat. Carry out the following checks to eliminate any external
causes. If no obvious problem can be found and replacement of the modelling lamp, flash tube or fuse
does not effect a cure then it is likely that an internal fault has developed. Always return the unit to an
authorised service centre if a fault is suspected after these checks. UNDER NO CIRCUMSTANCES
SHOULD YOU ATTEMPT ANY REPAIR yourself.
Flash/Misfire Warning
Following a flash, the unit will temporarily display READY on the red numeric displays for 5 seconds.
This serves as a convenient method of showing correct pack operation when two or more packs are
running flashing together. If the unit receives a trigger signal from any of the valid sources (TEST, IR
REMOTE, IR TRIGGER, SYNC) but fails to flash for any reason then the red numeric will display
“headfail”. Press – to clear the message. Increase the power setting to maximum and use the TEST
button to try and flash again. If the problem continues to happen on more than the odd occasion,
particularly at lower power settings, then it is likely that the flash head tube is wearing out. Before
replacing the tube, check that the trigger wire is correctly connected and is not shorted to or in close
proximity to the metal reflector. If the unit fails to flash at all then check the flash tube for signs of
damage or overheating.
If the unit fails to flash and the display warning is not given then the Sync. lead and/or camera should
be suspected. If possible check these with another flash system. Check the polarity of the Sync. from
the camera and use an adapter to reverse it if necessary. The QuadX 3000 supplies a SYNC. voltage
of +5V with respect to the chassis Ground.
OVERHEAT Warning
The unit is fitted with overheat protection that inhibits charging until the unit has cooled sufficiently. The
display flashes the READY LED and displays a warning message on the LCD while the overheat
condition exists. Overheat will normally only occur if the unit is flashed repeatedly at a fast repetition
rate. Slowing down the repetition rate will normally help keep the unit out of overheat. Dimming the
modelling lamp or turning it off may also help.
NOTE: The controls are inhibited during overheat to prevent inadvertent changes being made. The
overheat condition remains until the pack reaches a target lower temperature or is turned off and then
on after the pack has cooled by a few degrees.
The Control Panel Does Not Light
If the control panel does not light when the unit is switched on then first check that the AC power supply
to the unit is OK and that the thermal resets buttons on the rear are set. Under exceptional conditions
of use the internal fuse may blow. This is normal and is designed to protect the unit. Report the
problem to your local service agent. Do not attempt to locate and replace the internal fuse.
The Control Panel Lights but Does Not come To 'READY'
If this happens then first confirm that the AC power supply is adequate and within the prescribed limits.
Try switching the unit off, wait a minute, and then switch on again.
