General Trouble Shooting
COMMON PROBLEMS AND CAUSES
Unit does not charge. Probable causes:
1. Fuse blown. (Unplug and discharge the unit-Replace fuse.)
2. No line power to unit. (Check line cord and outlet.)
3. Unit is on, but will not charge. (Safety thermal detector activated by heavy use,
beyond specified Flashing Rates on page 9.)
4. Unit completely off, but is connected to power and is turned on. (Safety
thermal switch activated by internal discharge. Decreasing flash power setting
repeatedly with the down arrow key or placing the unit into STANDBY with
the remote control repeatedly causes the flash power to discharge through an
internal power resistor. If the resistor over-heats, a thermal switch will open
and cut off line power to the unit. After a 3-minute cool-off period, the power
will return. This is a unit-protecting feature and can be caused by user actions
or circuit failure.)
Modeling light does not turn on. Probable causes:
1. Lamp turned off. (Press FULL ON/OFF button until LED lights.)
2. Lamp burned out. (Inspect and replace, when cool. See SERVICE section of
this manual)
Light flashes by itself without apparent reason. Probable causes:
1. Defective trigger cord, or trigger cord incorrectly polarized.
2. Bright light falling on photoslave.
3. Poor connection in line cord.
4. Reverse connection on trigger cord connection at camera.
5. Some radio slaves will cause interference-consult slave manufacturer.
Trigger cord will not flash unit, but charge indicator shows that the system has charged.
Probable causes:
1. Defective trigger cord.
2. Defective flashtube. Turn unit off. Wait until cool, then replace flashtube.
(See SERVICE section of this manual)
Defective flashtube. Turn unit OFF. Wait until cool, and then replace flashtube. (See
SERVICE section of this manual)
Infrared not working. Probable causes:
1. Check for receiver model number to insure PLDIR-2 is being used and has
been plugged into the PowerLight properly.
2. Turn unit power OFF and then back ON. The electronic startup sequence must
detect the receiver is being used.
3. View the startup display sequence to insure “ir” is displayed. If “rado” is
displayed see wireless setup in Advanced Features section.
4. If using the Hand-Held controller, press the unit number on the keypad before
pressing any adjustment buttons. If using the Computer control, you must click
transmit at the unit window or transmit-all at the top of the screen.
