10.1 cooling
The heat dissipated by all key power pack components is constantly monitored by the on-board
processor. This protects the power pack against overheating and optimises its service life. In the
standby mode and if only the modelling light is used, the power pack fan is disabled. It begins to
operate as soon as this becomes necessary after a certain number of flashes have been fired.
10.2 thermal overheating display
To protect against overheating after extended flash series, the unit will automatically switch off. At
that stage, the following message will appear on the upper LCD display (15): "th" and the approxi-
mate time required for cooling will appear on the lower display. The cooling time is shortened if
the unit remains connected and switched on. Therefore, do not disconnect the unit from the mains
supply.
10.3 circuit breaker (11)
In the event of an electrical malfunction, the circuit breaker (11) will automatically disconnect the
power pack from the power source. The unit can be restarted by pressing the circuit breaker button.
If it disconnects again immediately the power pack must be serviced by an authorised service
station.
