DO NOT ATTEMPT TO LOCATE AND REPLACE THE INTERNAL FUSE YOURSELF. • Control Panel Lights Up But Ready Indicator Does Not Light Up If this happens, first confirm that the AC-line voltage is adequate and within the prescribed limits. Confirm that the Flash Thermal Reset Button on the Rear Panel is pushed in. Under exceptional conditions of use, this may trip. Switch the unit off, wait a minute, push the button in and then switch power on again. • Modelling Lamps Are Not Working If all of the modelling lamps are not working, first check to see if the Modelling Thermal Reset Button on the Rear Panel is out. If this is the case, DO NOT RESET IT until you have checked the head(s) for blown bulbs and/or fuses. • Power Pack Triggers Erratically Check to see if the power pack is being triggered by another flash source by turning the photocell off. 4 9 Getting Started Control Panel Before first using your power checked for basic operation 1. Remove the packaging and ensure 2. Set up a flash head. Be sure the protective on. 3. Plug the head into the socket of Channel A. 4. Set the Overall Power Selector to Symmetric/2400 A Variator to Full. 5. Set the Modelling Mode Selector to Intermittent/Proportional. 6. Set Audio Switch to On, Photocell Switch to Off and Fast/Slow Switch to Slow. 7. Connect the power pack to a 230V AC, 50/60Hz outlet using the power cord. 8. Set the Power On/Off Switch to On. The unit will show “2400” on the Channel A display. The pack will now charge to this setting. 9. Confirm after a few seconds that the Ready Indicator lights up, the Audio Ready Signal beeps and the flash head’s Modelling Light is on at Full brightness. 10. Use the Test Button to discharge the set power into the head. 11. Confirm that the head flashes, the power pack recycles and Ready Indicator 12. Repeat steps 8 and 9 with the Overall Power Selector set to Symmetric/1200, Symmetric/Asymmetric/1200, Asymmetric/600 and Asymmetric/300. Confirm that there is an appropriate change of light output with each change of setting. Use a flash meter if possible. 13. Reduce the Channel A Variator setting to -3.0 and confirm that the Modelling Light has dimmed. 14. Confirm that the head flashes, the power pack recycles and Ready Indicator lights up. 15. Switch the power pack off. Plug the head into channel B. 16. Set the Overall Power Selector to Asymmetric/1200 and both Channel Variators to Full. 17. This time both numeric displays will show “1200.” The power pack will now charge to this setting. 18. Confirm after a few seconds that the Ready Indicator lights up, the Audio Ready Signal beeps, and the flash head’s Modelling Light is on at Full brightness. 19. Use the Test Button to discharge the set power into the head. 20. Confirm that the head flashes, the power pack recycles and the Ready Indicator lights up. 21. Repeat steps 16 to 19 with the Overall Power Selector set to Asymmetric/600 and Asymmetric/300. Confirm that there is an appropriate change of light output with each change of setting. Use a flash meter if possible. You are now ready to begin using the generator. NOTE: If the unit has been left unused for six months or predominantly used with low power settings, it is recommended that the Power Level be increased to Maximum and the unit left switched on for at least 30 minutes occasionally to help preserve the life of the capacitors. Rear Panel NOTES: 1 The QUAD2400 displays the power available to each channel in watt-seconds on the two red numeric Power Level Displays marked Channel A and Channel B. 2 Beneath the Channel Power Level Displays are the Channel Variators. These control the individual power available from the Head Sockets A and B in 1/ 3 stop increments. NOTE: The individual Channel Variators and Power Level Displays are aligned with the associated socket. 3 The Fast/Slow Switch, Overall Power Selector and Modelling Mode Selector are AC Inlet 230VAC 50/60Hz 16A Flash Thermal Reset Button Modelling Thermal Reset Button The AC Inlet, On/Off Switch and Thermal ResetButtons are mounted on the rear panel. Power On/Off Switch common to both channels. 5 8 Function Function Flash Power Control The power pack is divided into A and B, and each is fitted with An LED display for each channel indicates channel. A single Overall Power Selector reduces total power by one or two f/stops and Channel Variator controls reduce each channel’s power by a further three f/stops in 1/3-stop steps. The Overall Power Selector has settings for both Asymmetric (A/B) and Symmetric (A+B) modes. The selected power in Asymmetric mode is available independently from any head is fitted in the other channel. The power available is controllable by using the appropriate Channel Variator and the associated display. The full selected power in Symmetric mode is only available A, providing that no head is fitted in the Channel B socket. The total power available is shown on the Channel A P...
