User manual BOWENS ESPRIT II 250

[. . . ] The Esprit 250 must not be used in an environment where moisture or flammable vapour is likely to come in contact with the unit. A fire hazard exists if flammable materials are placed in close proximity to either the flashtube or modelling bulb when the unit is in use. The charging and modelling circuitry of the Esprit 250 is protected by a 5A (F) 20mm fuse mounted on the rear panel (Fig. 1. Switch off and disconnect supply before changing fuse, modelling bulb or flashtube. [. . . ] Charge When first switched `ON' the green illuminated ON/OFF switch (Fig. 1. When the unit has charged to the level set by the flash power selector (Fig. 2. Note:- The Esprit 250 synchronising circuit is inhibited until the unit is 100% charged, unlike some other manufacturer's equipment that can be fired when only 80% charged. This ensures that every flash is identical. 7. 8. 9. Synchronisation Open Flash: For testing or multiple flash applications the Open Flash Pushbutton (Fig. 2. The Esprit has a built in photocell enabling the unit to be triggered by the flash from any other flash unit or a small camera mounted flash gun. The photocell is mounted behind the red transparent cover on the top of the Esprit. Sync Socket: The standard quarter inch jack type socket on the rear panel of the unit (Fig. 1. 1) may be used for direct connection to a camera set to `x' synchronisation. Two Esprit 250 flash units may be connected together using a `y' connector. An Infra Red Receiver or Omnicell may also be plugged into this socket. With the switch set to `Intermittent' the modelling light will go out when the unit is flashed and come back on when the unit comes to ready. This enables the photographer to see from the camera position that all Esprit units in use have fired. With the switch set to `Continuous' the modelling light remains on all the time. The modelling light may be varied in ratio with the flash power output by aligning the indicator line on the modelling output control knob (Fig. 2. 2). 10. -4- Bowens Esprit 250 Operating Instructions. 11.
