To mount the stand on the generator, lift the upper clamp on the stand fixture, then slip the stand through it and through the lower clamp as well. The stand will be locked in place when the upper clamp is released. G. [. . . ] However, re-trimming can be performed by any workshop authorized to service Profoto products. IMPORTANT: When the unit is not going to be used for a while the mains plug should be disconnected. This is necessary, so that automatic safety mechanism (pulse charging) can start up when the unit is put in use again. When the generator is pulse charging, or when initial charging is taking place, charging time can be considerably longer than normal (60 sec. In extreme cases, it can take several minutes. The PF Flash Head: The flashtube is mounted in a protective, frosted glass cover on a ceramic base. These are placed asymmetrically, so that it is not possible to insert the flashtube incorrectly. When mounting or dismounting the flashtube, hold out the safety catch to let the flashtube socket pass. Care must be taken when mounting or changing the flashtube not to damage the modelling lamp. The Twin Flash Head: The two flashtubes are mounted under a removable glass cover. When changing the flashtubes, dismount the glass cover by pressing together the two locking pins on the flash head, then lifting off the cover. The two flashtubes are mounted separately, each on its own ceramic base with metal pins, which permits the user to change the tubes independent of each other. After the glasscover has been removed, the modelling lamp can be changed in the standard manner. 14. THE CIRCUIT BREAKER The flash generator is equipt with an automatic circuit breaker which protects both the generator and the flash heads from overload. If overload occurs, the button controlling the fuse will protrude from the panel, signifying a warning. Because the circuit breaker governs only the modelling light and has no effect on the flash, the flash can still be used with the fuse in "warning" position, but the modelling light will not function. IMPORTANT: If the circuit breaker is in "warning" position, find the cause of the overload before returning the fuse to normal status. 13. It is an "all voltage" generator, which can be connected to the most common voltages: 90-130 V, 180-240 V, 50-60 Hz. The generator is connected to the mains by a special cable and switches itself into the correct input voltage range, thereby eli- 15. IR-PHOTOCELL/SLAVE The IR-Photocell on the generator panel serves as a flash trigger. It can be activated by another flash, or by an IR-sync attached to the camera's synchronization mechanism. The photocell can be turned off by flipping the switch located beside it on the generator. When a sync cable is in use however, the photocell is automatically disabled. [. . . ] The first charge, after mains cable connection, is always to full energy and always in a slow step mode (pulse charging). Thus, charging proceeds in stages, while at the same time the status of the capacitors is being gauged. Depending on the current leakage of the capacitors, which can be high when the generator has not been used for a while, initial charging time can vary. In extreme cases, it can take up to several minutes, but normally it takes less than 60 seconds. [. . . ]
