“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, preventing damage. This usually is caused by too many quick-discharges, resulting in the overheating of the unit’s circuits. (See flash rate chart) The unit remains 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.

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 suggested that all walls and ceiling be painted either white or light neutral colors for most reliable photoslave operation.

After the trigger cord is properly connected, check the synchronization with the camera. Adjust a light head to same height as the camera lens and face the light 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 the 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.)

Photocell/Photo Slave:

The sensor is built into the power supply and can be shut off by plugging in the sync. cord.

These robust lighting systems are perfect for studio setups or on-location shoots, offering versatility and convenience.

The PM400R and PM800 are known for their powerful performance capabilities. The PM800 boasts a maximum output of 800 watts, providing ample light for various photography genres, from portraits to large group shots. In contrast, the PM400R offers 400 watts of power, making it suitable for smaller setups while still delivering stunning results. The ability to adjust power settings allows photographers to fine-tune their lighting to achieve the desired effect, whether soft and natural or dramatic and stark.

A key feature of the PM series is the built-in modeling light, which enables photographers to visualize how the light will interact with their subject before capturing the shot. This feature is complemented by precise adjustment controls, allowing for easy manipulation of light intensity and quality.

All models in this series utilize advanced flash technology, ensuring consistent color temperature and flash duration. This is crucial for maintaining color accuracy throughout the shoot, minimizing the need for extensive post-processing. The fast recycling time further enhances workflow efficiency, allowing photographers to capture multiple frames quickly without sacrificing quality.

The design of the PM400R and PM800 includes a robust build, ensuring durability and longevity, even under heavy use. The lightweight design allows for easy transportation, making these lights perfect for photographers who frequently change locations. Additionally, the series is compatible with a variety of light modifiers, enabling users to customize their lighting setup to suit different styles and preferences.

Furthermore, the LED ready feature in the PM400 and PM800R ensures they can easily adapt to various lighting needs, allowing photographers the option to work with continuous lighting when necessary. This flexibility makes the series not only practical but also future-proof, adapting to the evolving demands of photography.

In summary, the Photogenic PM400R, PM800, PM400, and PM800R stand out for their professional-grade performance, versatile features, and user-friendly design. With these lights, photographers can elevate their craft, achieving stunning results that truly capture their artistic vision.
