“Er-3” message means over heating has occurred. This could be internal or by
exceeding the recommended flash frequency. (See flash rate chart) Once “Er-
3” is displayed a “COOL” mode is activated to cool off internal components.
This usually is caused by too many quick-discharges resulting in the
overheating of the unit’s circuits. (See flash rate chart) The unit counts down in
this COOL mode for approximately 4 minutes. This is an electronically timed
period and turning the power OFF will not shorten this COOL period.
“- - - - “ message means a misfire has occurred. To reset press the test fire
button or turn the power OFF. If the “----“ continues, turn the unit off and have
service performed.
Synchronization and Triggering:
Triggering is accomplished by using a built-in photoslave or a trigger cable from the
power supply to the camera shutter contacts of ”X” or “zero” delay. Other units in the
system are then triggered by photoslave operation. It is best to connect the fill light
directly to the camera since it will be positioned furthest back in the studio and will
usually provide sufficient illumination to trigger the other units. It is suggested that all
walls and ceiling be painted either in white or light neutral colors for most reliable
photoslave operation.
After the trigger cord is properly connected, check the synchronization with a film
camera. Adjust the lighting unit to same height as the camera lens and face the lights into
the lens. The lens aperture should be open to its fullest extent and set on “X” or “zero”
delay. Remove the camera back. It is best to perform this test with the modeling lamps
turned off.
While looking at the lens through the back of a film camera, operate the shutter.
A few sheets of white paper in front of the lens will cut down the brilliance of
the flash and aid in making the observation. The flash of the light should then
appear as a circle the same size as the aperture. If the circle is flattened on the
sides, or if no light appears through the lens, the shutter is not synchronized. If
the shutter appears not to be synchronized, a reputable camera repair shop
should check the shutter contacts.
The sync polarity is Positive on center pin of cable connectors (Photogenic part
PLTC, and defined in ISO 518.)
Sync voltage is 12 vdc (Spec. = less than 24 vdc per ISO 10330:1992E, and
greater than 9 vdc for Wein photo slave at 10 microampere drain.) Internal 240
ohm discharge limit, with 68 k ohms continuous limit.
Sync signal = negative pulse, 10 microseconds or longer, from sync voltage to
1.6 vdc or less (per ISO 518.)
