Photocell
The built-in photocell [6] will sense flash release as well as IR-signals from most IR-transmitters.
The photocell is disabled when the button marked SLAVE [8] is released.
Signals, Audible & Visible
The green indicator [3] below the handle will light up once the generator is connected to the
mains outlet. The white ready lamp [9] will light up when the generator is fully charged. The
button will not light up when the modelling light control [12] is in the OFF position. At the first
initial charge, when the generator is connected to the mains supply, or when the energy output
has been changed the white ready lamp [9] will flash. Dumping the energy is then required. At the
next recharging the lamp will light up with a constant light. A short ”beep” can be heard when
the generator is fully recharged. Releasing the button marked SOUND [10] will turn off this
signal. If a flash is fired before the generator is fully charged a long ”beep” can be heard thus
indicating an underexposed frame.
Safety Functions
After having connected the generator to the mains outlet the first charge is always made to
maximum energy for capacitor formation. This is important in order to avoid damage after
leaving the generator unused for some time. If the generator for any reason whatsoever over-
heats, the recharging will stop completely. After a while, when the temperature has gone down
sufficiently, the generator will start recharging at a normal pace again. This automatic protec-
tion system will only start up under extreme conditions, for instance when the air vents are
blocked for some reason.
PLEASE NOTE: The air vents of the generator must never be blocked or covered in any way.
Never store your flash equipment in a car on a hot and sunny day. Never use a generator that is
placed inside a case or transport box. Avoid storing the generator close or below the freezing point,
which can lead to loss of capacity (flash output) and risk of condensation when used in a warmer
surrounding immediately. Do not expose any flash equipment to wet or humid environments or
extreme electro-magnetic fields.
