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 fuse does not effect a cure then it is likely that an internal fault has developed. [. . . ] The Esprit Digital 1000DX is fitted with a cooling fan and will cool faster if left switched on. The unit is equipped with overheat protection, not to limit performance but to prevent damage under abnormal operating conditions. Repeated operation of the overheat protection should be avoided by decreasing the flash power or repetition rate. Dimming or turning the modelling lamp off will help prevent overheating. Whenever possible, avoid rapid high power flashing when using restrictive reflectors such as a snoot or grid reflector, particularly if the unit is pointing downwards. The table below shows maximum number of flashes permissible at various flash rates and flash settings before allowing the unit to cool. This cannot cover all combinations but should be used as a guide to determine the maximum flash rate to meet your requirements. AC Supply The unit operates from an AC Line voltage within the range 95V to 130V with a nominal frequency of either 50Hz or 60Hz. Ensure that the Power ON/OFF switch on the unit is set to OFF. Use a cable supplied by your Bowens dealer to connect to the AC supply. A 3-wire, earthed (grounded), supply system must be used to ensure safe and reliable operation of the unit. Triggering System The Esprit Digital can be triggered by any of the following methods: · TEST/OPEN FLASH RELEASE Button For testing or multiple flash applications the TEST button can be used. The unit will only flash if the unit is charged and the `READY' LED is either lit or flashing. · EXTERNAL SYNCHRONISATION Socket The standard ¼" jack-type socket on the rear panel may be used for direct connection to a camera set to "X" synchronisation. When these are first selected the appropriate display will be automatically selected for checking or adjustment. If the `FUNCTION' or `UP'/'DOWN' buttons are not pressed within 4 seconds then the controls and display will automatically return to the default `FLASH' function. Use the `FUNCTION' button to reselect if required. Functions likely to require less frequent adjustment are accessible via an `OPTIONS' sub-menu. This allows the user to customise certain functions without complicating the main controls. INTERMITTENT Option The preferred mode for the `INTERMITTENT' function can be selected from the `OPTIONS' submenu as follows: Option Description NORMAL. Only available when the LAMP is switched ON (PROP, IND or 100%). The Modelling Lamp will extinguish while the unit recharges and light again when the unit reaches `READY'. If the unit fails to flash for any reason then the LAMP will not be extinguished. Available with the LAMP either ON or OFF. When the unit reaches `READY', after being flashed, the Modelling Lamp will intensify to full brightness and then dim before returning to the previous setting (or to OFF). The exact effect will depend on the current lamp setting. [. . . ] Switch the Infrared Remote Receiver on or off using the `REMOTE' button. IR Remote Control is enabled when the associated LED is lit. `C' - REMOTE CONTROL CHANNEL Display Mode When the IR Remote is switched on the unit will automatically enter the `CHANNEL' display mode to allow adjustment. The `C' before the displayed value indicates this mode: Display Range X Description Display IR Channel number. Use `UP' or `DOWN' to select. INTERMITTENT Button This feature uses the Modelling Lamp to indicate that the unit has flashed correctly and recharged to `READY', it is in addition to the normal indication. [. . . ]
