2403CX LV Description of Controls
1) Power
— turns power supply on and off.
2) Model Light
— turns model lamps on and off.
3) 800Ws Isolate/Combine
— when in isolate, this switch isolates the
800Ws channel from the 1200Ws channel and provides two
Light Unit
Outlets
per channel. When in combine, will provide 2400Ws among 4
Light
Unit Outlets
.
4) 400Ws Isolate/Combine
— when in isolate, this switch isolates the
400Ws channel from the 1200Ws channel and provides two
Light Unit
Outlets
per channel. When in combine, will provide 1600Ws among four
Light Unit Outlets.
(With both 800Ws and the 400Ws switches in combine,
2400Ws is available through any of the six Light Unit Outlets, divided equally.
See diagrams on the side of the power supply and page 15 for detailed
examples of the ratio system).
5) Variable Power Control
— simultaneously controls power of all three
channels, with ten positions down to -3 stops (1/8 power). Power ratios
among the light units are unaffected since there is a proportional change in all
power levels.
6) Recycle Rate
— controls recycle rate.
7)Charge/Ready/Push to Flash
— red
Charge
light is illuminated whenever
the power supply is charging up or down to the selected level. Green Ready
light is lit whenever the 2403CX LV is fully charged to the selected power
level. An audible beep will sound when the green
Ready
light comes on.
Push to Flash
button is for manual triggering of flash for testing or open flash
application.
2403CX LV Operating Instructions
In addition to the general instructions on page 4, the following
information and techniques are crucial for the proper use and care of the
2403CX LV power supply.
Set
Isolate/Combine
switches and
Variable Power Control
as desired.
See the side of the power supply for various ratio combinations. With the
Variable Power Control
in the Full position, power is determined by the
choice of outlets and position of ratio switches. The
Variable Power Control
simultaneously changes the power level of all three channels. Rotating the
Variable Power Control
immediately adjusts the power level of the 2403CX
LV. The power supply does not need to be discharged between settings.
Turn
Power Switch
on. The red
Charge
indicator will illuminate. After a
few seconds, the green
Ready
indicator will illuminate and an audible beep
will sound. (The beep will not be produced when a very small power change is
made. Changing the power level by a third f-stop or so is done very rapidly
with the 2403CX LV; the
Ready
light will usually remain on) The power supply
is now charged to the selected level, and ready to fire.
Do not
immediately
fire the unit on the first use or when the unit has been idle for periods over 3
weeks. Allow several minutes for the power supply’s capacitors to form.
Push to Flash
button may be depressed to verify proper system operation.
When Power is on, be sure
Ready
indicator is illuminated before switching
Power
or
Fast/Slow.
Do not
move these switches while the unit is recycling.
When disassembling the system, turn
Power
switch to the off position.
The 2403CX LV power supply will automatically discharge its storage
capacitors.
Do not
push the
Push to Flash
switch before turning power
supply off. This may damage power supply. Power supplies may flash their
light units when turned off. This is normal.
Unplug power cord from outlet, then disconnect light units from power
supply.
8) Remote
— for use with optional Remote Variable Power Control (#11237)
to allow exposure bracketing from the camera position. The
Variable Power
Control
must be in the full position for the power levels to be correctly
indicated by the remote control.
9) Sync
— socket to connect camera or slave to power supply.
10) Power Input
— socket for AC power cord.
11) Light Unit Outlets (6)
— sockets for connecting from one to six light
units to power supply.
