Bowens Esprit 1500 Operating Instructions.
4.
Power Supply Connections
190-250 V AC 50 Hz. Use mains lead supplied to connect to mains supply.
5.
Operation
The green illuminated On/Off Switch (Fig.1) on the rear panel controls the
power to both the flash and the modelling lamp. Setting the switch to 1 turns
the unit 'ON', with the switch illuminated, and 0 turns the unit 'OFF'.
When the unit has charged to the level set by the Flash Power Control (Fig.2)
the green 'Ready' Indicator (Fig.2) will light. Your Esprit 1500 is now ready
to fire.
Note:- The Esprit 1500 synchronising circuit is inhibited until the unit is
100% charged. This ensures that every flash is identical.
6.
Synchronisation
Open Flash:
For testing or multiple flash applications the Open Flash Pushbutton (Fig.2)
can be used. The Esprit has a built in photocell enabling the unit to be
triggered by the flash from any other flash unit or a small camera mounted
flash gun. The photocell is mounted behind the red transparent cover on the
top of the Esprit.
Sync Socket:
The standard quarter inch jack type socket on the rear panel of the unit (Fig.1)
may be used for direct connection to a camera set to 'x' synchronisation. Two
Esprit 1500 flash units may be connected together using a 'y' connector. An
Infra Red Receiver or Omnicell may also be plugged into this socket.

Flash Power Selection / Indication

available. The power selected, 500, 1000 or 1500 Ws, is shown on the Digital
Power Display (Fig.2) and represents a coarse control range of 1
The Flash Power Control (Fig.2) provides a continuous adjustment within the
range selected, over a five f-stop range from full to one thirty second (
power. Rotating the Flash Power Control (Fig.2) from full to half, half to
quarter, quarter to eighth, eighth to sixteenth and sixteenth to thirty second
gives a reduction in output equivalent to 1 f-stop for each step.
The total control range using the Flash Power Control and Flash Power
Selector Switch is 6
The auto-dump feature enables lower flash powers to be selected without
requiring the unit to be flashed first to dump the higher power. The digital
display blinks during the power dump to provide an indication of the status.

modelling light is 'OFF'.
