[. . . ] TO TAKE PROPER CARE OF THE CONDENSERS IT IS NECESSARY TO FORM THEM AT LEAST ONCE A MONTH. THIS IS BEST DONE BY FLASHING 5-6 TIMES IN THE FLASH SEQUENCE POSITION "S" (5) WITH THE MANUAL FLASH RELEASE (6). FORMING TIME ABOUT 30 MINS. Lamp Connection 1 to 4 lamps can be connected to the generator Pro-2 whereby the total energy is divided for outputs of l/l, l/2, l/4 + l/4. 22. 303. 00 it is also possible to connect 4 lamps with a power split of l/8, l/2, l/4 and l/8 (7). [. . . ] The lamp contact must be inserted into the generator socket correctly and the rear lock must catch. WHEN THE RED CONTROL LAMP LIGHTS UP, THE LAMP PLUG MUST NOT BE ACTUATED. THE RED LAMP SHOWS AN UNEVEN LOAD DISTRIBUTION OF THE CONDENSER PACKS AND GOES OUT AFTER A SHORT TIME. 1 When connecting only one lamp the power output corresponds to the indications on the outlets of the generator. When connecting two or more lamps, the corresponding power indications are correct only if out let 1 (full power) is not used. If outlet 1 is used with other outlets the entire power of the generator is divided evenly between the connected lamps. The following combinations are possible: 2 Lamp-split Cable 22. 303. 00 This short lamp-split cable is connected to outlet 1. A switch-action built into this lamp-split cable causes outlet 1 to be separated from the full power and to be connected to outlet 4, whereby the quarter power of this outlet is divided between two lamps. In order to maintain the one-eighth power, outlet 1 must always be connected to lamps through lamp-split cable 22. 303. 00. Diagram of Connections + Lamp-split cable Charging Pro-2 is equipped with a red charge control lamp (8). A s soon as the unit is charged the red lamp extinguishes and the green lamp (4) shows that it is ready for flashing. IMPORTANT WHEN THE RED CONTROL LAMP IS LIT NO LAMP I PLUG MAY BE ACTUATED. forming the condesors; where there charging is also recommended, since then be over-strained. The the switch under the carrying handle. The charging time can be Slow loading is used for are weak mains, the slow the mains fuses will not the charging time is 1. 8 change-over is done with VARIO-Model Pro-2 generators are also available in Vario-version. 20. 122. 00 can subsequently be built-in by our sole agents unless it was factory fitted. In this way the unit can be operated with a modeling light proportional to the flash power. Stick-light This is a complete lamp head with quartz flash tube and halogen modeling light. In order to exchange the halogen modeling light, remove the wire hoops of the glass cylinder. whereupon the modeling lamp can be removed. When changing the flash tube it is recommended that it be changed completely together with the base. 6 Operation Immediately after switching on the main switch (3) the green control lamp (4) lights up briefly, A slight hum indicates that the power supply is on. If the unit is switched on after longer intervals it is normal that a hum is heard and that the green lamp sometimes goes out. (In this case the condensors then consume more residual current. ) As soon as the green ready-indicator lights up the unit is ready for flashing. The green ready-light goes out after releasing the flash, and the generator charges again. If a flash is released during charging, the charging operation must be briefly interrupted, whereupon the green ready-indicator lights up. Short releases of partial power (l/4, l/2 etc. ) make the red control lamp (8) light up briefly. This indicates that the load in the condensor pack is uneven, due to the partial release of power. The red load-control lamp will only extinguish again w h e n a l l condensors are fully charged. [. . . ] The red load-control lamp will only extinguish again w h e n a l l condensors are fully charged. This is a simple control of t h e load position which also increases the flash reliance. WHEN PLUGS THIS AFTER THE RED LOAD-CONTROL LIGHTS UP, THE LAMP MUST NOT BE ACTUATED. ALSO APPLIES FOR APPROXIMATELY 10 SECONDS SWITCHING OFF THE GENERATOR. Guide Numbers It is possible to find out the proper f-stop with an ordinary exposure meter. [. . . ]
