Important Safety Notes - Please Read Before Operating Pack

Please read and follow these basic safety instructions:

z READ and UNDERSTAND the instructions and specifications.

z ONLY connect to an AC (Alternating Current) power supply.

z NEVER connect to a DC (Direct Current) supply.

z ALWAYS use a grounded AC outlet.

z ALWAYS use a three core cable of at least 10 or 15 Amp rating as supplied.

z WHEN practical, unplug the Pack from the electrical outlet when not in use.

z ALWAYS remove the power cord by gripping the plug, NEVER pull the cord.

z ALWAYS ensure that any extension cord used has a suitable current rating to

prevent overheating. NEVER use coiled extension cords.

z NEVER replace the fuse with one of a different type or rating. See Specification

for correct value/type of fuse.

z ALWAYS avoid placing AC power cords and Flash Head cables where they can

be tripped over.

z NEVER place heavy objects on top of the AC Power cord or Flash Head cables

and avoid running them over sharp or hot objects.

z NEVER use the equipment with damaged cables. Have them replaced as soon as

possible. NEVER attempt to repair them yourself.

z NEVER use the Pack or Flash Heads in an environment where moisture, water

vapour or inflammable liquids, vapour or materials may come into contact with the

Pack or Flash Heads. The flash output as well as the modelling lamps can cause

ignition of or damage to materials that may come into direct or close contact with

the Flash Heads.

z ALWAYS keep ALL vents in the Pack and Flash Heads clear of obstructions at all

times.

z ONLY switch the Pack ‘ON’ AFTER the Flash Head/Heads has/have been

correctly connected.

z ALWAYS ensure that the Flash Head cable connectors are correctly fitted before

use.

z ALWAYS remove the Flash Head covers before using.

z ALWAYS turn OFF the Pack, disconnect from the supply, unplug the Flash

Head/Heads and allow them to cool before:

a). Replacing the modelling lamp in Flash Head.

b). Replacing the flash tube in Flash Head.

c). Replacing the fuse in Flash Head or Pack.

z If the Pack is not used for more than a couple of months then it is advisable to just

switch the Pack on periodically for an hour or so with the FLASH variators set to

maximum - there is no need to use a Flash Head.

General Features

The DUO 2400 Pack has been designed to produce the most compact, versatile and

easy to use flash source available today. Features include:

z Two independent Channels, each having a Quad style head socket, ‘FLASH’

Variator, Modelling ‘LAMP’ Variator and Modelling ‘LAMP’ Control switch.

z An ‘ISOLATE’ mode which allows each of the Channels to be independently

controlled with up to half the total flash capacity of the Pack.

z A ‘COMBINE’ mode which provides the total flash capacity of the Pack from

EITHER or BOTH sockets with a single set of controls.

z Modelling ‘LAMP’ Variator and Modelling ‘LAMP’ Controls independent of Flash

controls.

z ‘POWER’ display of the selected MAXIMUM flash capacity of the Pack and a

visible ‘READY’ indication.

z Built in, sensitive ‘SLAVE’ Photocell with ON/OFF switch.

z AUDIBLE ‘READY’ Sounder with ON/OFF switch to give audible indication of

when the Pack is ready to fire.

z A built in fan automatically switches in to cool the unit during periods of heavy use.

z Overheat protection which protects the unit in the event of extended periods of

continuous flashing and also in the unlikely event of failure of the cooling fan.

z EMC (Electro-Magnetic Compatibility) filters fitted.

Power Supply Connection

z The Packs are designed to operate on an alternating current (AC) supply of 200 to

253 Volts, 50 Hz. The Packs must NEVER be connected to any direct current

(DC) supply.

z The Packs conform to current standards which require connection to a properly

grounded power supply. The 3 core power cord supplied with each Pack is colour

coded as follows:

Live (L): Brown

Neutral (N): Blue

Earth (E): Green/Yellow

z If a moulded plug is not fitted it is essential that all 3 wires are connected to the

correct plug pins in accordance with the above colour code and that the cable is

securely clamped in the supply plug.

AC Power Switch

z The AC Power switch connects power to both the flash and modelling circuits.

The switch is illuminated green when ‘ON’.

z ALWAYS switch ‘OFF’ the unit before plugging or unplugging Flash Heads,

changing fuses or modelling lamps.

Circuit Protection

z Protection of the Modelling circuitry is by means of a 20mm fuse mounted on the

control panel of the Pack. The fuse is rated at 15 Amp (T) and should never be

replaced with a fuse of a different type or rating.

- 8 -

z 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

z 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.

z It should be noted that switching to ‘SLOW’ charge will also extend the charge

times at maximum power - See specifications for details.

Flash Heads

z 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.

z 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.

z Heads from the BOWENS 220/240V QUAD system may be used with the Pack

but with the following limitations:-

1. Splitter boxes SHOULD NEVER

be used.

2. A 1.5k QUAD Head will only operate in combination with another head,

of any power rating. The Pack is designed not to charge if the total

power rating of the heads fitted is less than that of the Pack.

z For detailed information on the operation of the heads, general maintenance, flash

tube and lamp replacement, and accessories available, please refer to the

appropriate Instruction Manuals supplied with the head.

Flash Power Selection/Indication

z By using the two Flash Head sockets and associated controls, asymmetric and

symmetric combinations of flash power are available from one or two Flash

Heads.

z The ‘POWER’ switch sets the TOTAL MAXIMUM flash power available from the

Pack. The MAXIMUM power selected, 600, 1200 or 2400W-s is shown on the

digital display and represents a coarse control range of 2 f-stops. This power can

be made available from EITHER or BOTH sockets depending upon the setting of

the ‘COMBINE/ISOLATE’ switch.

z The ‘COMBINE/ISOLATE’ switch in combination with the number of Flash Heads

fitted, gives a further f-stop adjustment. This provides the facility to have two

separate Channels, A and B, with individual sets of controls, OR to combine them

with one set of controls.

- 9 -

z When switched to ‘ISOLATE’ both the ‘ACTIVE’ LED’s will be lit, indicating that the

two ‘FLASH’ variators and Channels operate independently, with each providing a

continuous adjustment over a 3 f-stop range. Each Channel has a maximum

output of half that set by the ‘POWER’ switch which may be used to adjust the

overall light level without affecting the balance between channels set by the

‘FLASH’ variators.

z When switched to ‘COMBINE’, only the ‘ACTIVE’ LED for Channel A will be lit and

both A and B Channels will be controlled by the Channel A ‘FLASH’ variator which

provides a continuous adjustment over a 3 f-stop range. The maximum output set

by the ‘POWER’ switch is available from EITHER socket.

z The total control range using a combination of Flash Heads, ‘FLASH’ variators,

‘POWER’ switch and ‘COMBINE/ISOLATE’ switch is 6 f-stops.

z In general the ‘POWER’ switch should be set to the lowest setting and the

‘FLASH’ variator(s) set to the highest, consistent with the flash power and the

distribution between heads required. This method provides the shortest flash

duration for a given power output. Fitting two heads will also reduce the flash

duration.

z Whenever the ‘POWER’ or ‘FLASH’ controls are changed, flash the Pack once

using the ‘OPEN FLASH’ button to ensure that the next flash is of the required

power.

z A study of the quick reference tables on pages 16 and 17 will explain the possible

combinations of MAXIMUM power available to the individual Flash Heads.

Modelling Lamp Output/Control

z Refer to the Instruction Manual provided with the head for more details of the controls

and maintenance of the head.

z The Modelling Lamp for each Channel is controlled by a ‘LAMP’ variator and a

‘CONTINUOUS/OFF/INTERMITTENT’ switch on the control panel. Most Flash Heads

are fitted with a Modelling Lamp ‘ON/OFF’ switch which allows individual Lamps to be

turned off.

z The ‘COMBINE/ISOLATE’ switch determines which Modelling Lamp

‘CONTINUOUS/OFF/INTERMITTENT’ switch and ‘LAMP’ variator have control. With

the switch set to ‘COMBINE’ the Channel A switch and variator have control over

BOTH Modelling Lamps. The Channel B switch and variator will have no effect and

neither of the indicator LED’s will be lit. With the switch set to ‘ISOLATE’ the Channel

A and Channel B switches and variators have independent control over the Modelling

Lamps in their respective Channel.

z Set the appropriate Modelling Lamp switch to the centre position to switch the

Modelling Lamp OFF for the required channel. Neither indicator LED will be lit for that

channel.

z Set the appropriate Channel Modelling Lamp switch to ‘CONTINUOUS’ to switch the

Modelling Lamp ON. The Green indicator LED will be lit and the Lamp brightness can

be continuously adjusted over a 3 f-stop range using the ‘LAMP’ variator for that

Channel.

z Set the appropriate Modelling Lamp switch to ‘INTERMITTENT’ to enable the

Modelling Lamp to go out when the Pack is flashed and come back on again when

‘READY’. The Red indicator LED will be lit and the Lamp brightness can be

continuously adjusted over a 3 f-stop range using the ‘LAMP’ variator for that Channel.

- 10 -

Open Flash

z Press the ‘OPEN FLASH’ button to test the flash operation of the Pack and head(s).

When decreasing the power setting of the Pack using the ‘FLASH’ Variator(s) or

‘POWER’ switch simply flash once using this button to adjust to your new setting.

External Synchronisation

z A 6.35mm, low voltage, ‘SYNC’ jack socket is provided on the control panel for

external synchronisation. The socket accepts the supplied standard Sync. lead for

direct connection to the camera.

Photocell

z The built in Photocell may be used for remote triggering from another flash source or a

Remote IR Trigger. Set the ‘PHOTOCELL’ switch to ‘ON’ to enable the Photocell. The

Red indicator LED below the switch will be lit when the Photocell is in operation.

Sounder

z Set the ‘SOUNDER’ switch to ‘ON’ to enable the Sounder. The Red indicator LED

below the switch will be lit when the Sounder is in operation. When the Sounder is

switched ‘ON’ it will give a short beep when the Pack comes to ‘READY’.

- 11 -

Overload Protection, Cooling Fan And Overheat

z A manual reset Circuit Breaker and thermal cut-out system is provided to prevent the

Pack from overheating under heavy conditions of use.

z The operation of the thermal cut-out is highly dependent upon the conditions of use

and is typically as follows:-

• Pack working normally - Pack under moderate use at normal operating

temperature with low to moderate ‘POWER’ setting, ‘SLOW’ charge rate and/or

slow to moderate flash rate.

• Pack NOT ‘READY’, AC Power Switch neon lit, ALL other control panel

indicators off - Pack was previously under heavy use with moderate to maximum

power setting, fast recycling and warm to hot. Thermal cut-out has operated and

will be automatically reset after a cooling period.

• Pack NOT ‘READY’, AC Power Switch neon AND one or more other indicators

on the control panel are lit and the top panel Circuit Breaker has operated. Pack

previously under very heavy use with fast recycling and hot. In this condition the

Circuit Breaker button will project from the panel and may be manually reset after

allowing a short cooling period. Under certain conditions this may also be

combined with operation of the thermal cut-out.

z A thermostatically controlled fan senses the internal temperature within the Pack.

Under normal conditions of use the fan is unlikely to operate but when the Pack is

used heavily the fan will cut in to lower the internal temperature allowing many more

shots to be taken. Providing that power is applied and the Pack is switched on, the fan

will operate independently of the Circuit Breaker and thermal cut-out.

z Operation of the overload protection can be avoided by checking and modifying the

conditions of use:-

• Ensure that the cooling vents of the Pack are clear of obstructions.

• Use the ‘SLOW’ charge setting if the ‘FAST’ setting is not necessary.

• Reduce the flash rate.
