Warnings Signs and Troubleshooting

If the unit appears to have developed a problem, first establish that it is a genuine internal problem and not a case of normal operation such as overheating. 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 flash head fuse does not eliminate the problem, then it is likely that an internal problem has developed. Always return the unit to an authorized service centre if a problem is suspected after these checks. UNDER NO CIRCUMSTANCES SHOULD YOU ATTEMPT ANY REPAIR YOURSELF.

• Overheat Warning

The power pack is fitted with a thermostatically controlled fan, but under extreme conditions of use the power pack may still overheat, even with the fan running. Flashing less frequently and/or using the Slow Charge Mode will normally help prevent this from happening.

Overheat protection is provided to inhibit charging until the unit has cooled sufficiently to operate normally. The Power Level Displays will flash “Overheat” warning while the overheat condition exists.

NOTE: The overheat condition remains until the power pack reaches a safe operating temperature or the unit is turned off and allowed to cool.

• Control Panel Does Not Light Up

If the Control Panel does not light up when the unit is switched on, first check the AC power-cord connections and check to make sure the AC outlet is working. Under exceptional conditions of use or component failure, the Internal Fuse may blow. This is designed to protect the unit. Report the problem to your local service agent. DO NOT ATTEMPT TO LOCATE AND REPLACE THE INTERNAL FUSE YOURSELF.

• Control Panel Lights Up But Ready Indicator Does Not Light Up

If this happens, first confirm that the AC-line voltage is adequate and within the prescribed limits. Confirm that the Flash Thermal Reset Button on the Rear Panel is pushed in. Under exceptional conditions of use, this may trip. Switch the unit off, wait a minute, push the button in and then switch power on again.

• Modelling Lamps Are Not Working

If all of the modelling lamps are not working, first check to see if the Modelling Thermal Reset Button on the Rear Panel is out. If this is the case, DO NOT RESET IT until you have checked the head(s) for blown bulbs and/or fuses.

• Power Pack Triggers Erratically

Check to see if the power pack is being triggered by another flash source by turning the photocell off.
