[. . . ] Refer to the section on operation of the controls if required. Test flash the unit by pressing the TEST button. Excess energy is automatically dumped when the flash power setting is reduced. Both increasing and decreasing the power setting generates heat inside the unit. Therefore avoid repetitive Up and Down power changes. Refer to page 12 if you intend to make continuous use of the fast recycling feature of the unit. NOTE: If the unit is left unused for 6 months or predominantly used at low power settings it is recommended that the power be increased to maximum and the unit left switched on occasionally for at least 30 minutes to help preserve the life of the capacitors. You are now ready to use the system. FITTING THE MODELLING LAMP Always switch off and disconnect from the supply before fitting or replacing the modelling lamp. Wait a few minutes for the lamp and tube to cool and for the unit to self-discharge. The unit has a flash off and auto-dump feature that operates whenever the unit is switched off. This is designed to quickly reduce the capacitor voltage to a `safe' value but it is still advisable to leave the unit for as long as possible before changing either the lamp or flash tube. Screw the modelling lamp into the ES lamp holder in the centre of the reflector. If the new lamp fails to light then check the fuse, as this may blow when a lamp fails. Replace a blown fuse with one of the correct type and rating. 12 5 Esprit Digital Operating Instructions FLASH DUMP Option The preferred mode for the `AUTO-DUMP' function can be selected from the `OPTIONS' submenu as follows: Option Description Flash dump off. Always resistively dumps excess energy whenever the FLASH setting is reduced. This method attempts to reduce the power in the shortest possible time whenever the FLASH setting is reduced. The unit determines whether to resistively dump the excess stored energy or to dump it quickly by automatically flashing the unit. MAIN CONTROLS & DISPLAY Refer to Fig. 2. The `FUNCTION' button, the `UP' , 'DOWN' buttons and the three-digit display provide a simple means of setting and displaying the main functions. Other buttons are used to access individual functions. The unit is designed to retain all settings indefinitely. If for any reason the memorised settings become corrupted then default settings will be used instead. Fd. 0 Fd. 1 `FUNCTION' Button The `FUNCTION' button is the main display control and selects the required function for display or adjustment. Each press of the button selects the next available function as shown by the leftmost digit or digits. [. . . ] Press the `INT' button to switch this function on or off. The associated LED is lit when `INT' is selected. Depending on the `OPTION' setting this mode may be unavailable when the Lamp is `OFF'. When this is the case, and the sounder is on, a long warning beep will be given when the button is pressed to indicate that it cannot be selected. [. . . ]
