Fast/Slow Charge Switch; Flash Heads; Flash Power Selection/Indication - Bowens DUO 2400 PACK Operating Instructions Manual

Protection of the Flash circuitry is by means of a Circuit Breaker mounted on the
control panel of the Pack. This will operate under extreme conditions of use and
can be manually reset after a short period of cooling by depressing the button until
it locks down.

FAST/SLOW Charge Switch

The 'FAST/SLOW' switch should be set to 'SLOW' if the current capacity of the AC
power supply is limited or fast recycling is not required. Switching to 'SLOW' will
reduce the current drawn from the supply by approximately 1/3rd.
It should be noted that switching to 'SLOW' charge will also extend the charge
times at maximum power - See specifications for details.

Flash Heads

The Packs are designed to be fitted with one or two DUO-LITE Flash Heads
(BW-3015), with a maximum modelling lamp rating of 650W.
To fit or remove a Flash Head, first ensure that the Pack is switched off and
disconnected from the supply. To fit a head, insert the tab on the front of the
Flash Head plug into the socket and then press down firmly on the cable entry end
to ensure latched retention. To remove a head, press the spring latch away from
the plug and lift from the cable entry end.
