‘L’ - LAMP Display Mode
When the ‘LAMP FUNCTION’ is switched to ‘INDEPENDENT’ mode the display and controls are
automatically set to the ‘LAMP’ mode to allow adjustment. An ‘L’ before the displayed value
indicates this mode:
Display Range
X.X Description
LX.X
5.0 to 10
Display Lamp power value. Use ‘UP’ or ’DOWN’ to adjust.
If no adjustment is attempted within 4 seconds then the display will revert to the default ‘FLASH’
mode. If the value needs to be reviewed or adjusted later then use the ‘FUNCTION’ button to
select the ‘LAMP’ mode.
The LAMP power is adjustable over a 5 f-stop range (6 f-stops) in 1/10 f-stop increments using the
‘UP’ and ‘DOWN’ push buttons. Adjustment and display of the ‘LAMP’ power in ‘INDEPENDENT’
mode is identical to that of the ‘FLASH’ power.
AUXILIARY FUNCTIONS
SOUNDER Button
Switch the sounder on or off using the ‘’SOUND’ button. The sounder is on when the associated
LED is lit. The sounder will give a short beep whenever active keys are pressed. Longer beeps
or repetitive beeps provide warnings, the meaning of which is given in the appropriate section.
INTERMITTENT Button
This feature uses the Modelling Lamp to indicate that the unit has flashed correctly and recharged
to ‘READY’, it is in addition to the normal indication. Press the ‘INT’ button to switch this function
on or off. The associated LED is lit when ‘INT’ is selected. Depending on the ‘OPTION’ setting
this mode may be unavailable when the Lamp is ‘OFF’. When this is the case, and the sounder is
on, a long warning beep will be given when the button is pressed to indicate that it cannot be
selected.
The user may select one of two indicating modes for this function by means of the ‘OPTIONS’
sub-menu. See ‘OPTIONS’ for a description of how to access this mode.
The default setting is ‘
In.0
’, for Normal intermittent operation. The ‘INTERMITTENT’ function in
this mode is only available when the lamp is switched ON (
PROP, IND or 100%
). When the unit
is flashed the Modelling Lamp will extinguish while the unit recharges and will light again when the
unit reaches ‘READY’.
The optional setting is ‘
In.1
’, for Pulse Mode operation. The ‘INTERMITTENT’ function in this
mode is available whether the lamp is on or off. After the unit is flashed and the unit recharges to
‘READY’ the Modelling Lamp will intensify to full brightness and then dim before returning to the
previous setting (or to OFF). The exact effect will depend on the actual lamp setting
If the unit fails to flash for any reason then the chosen sequence will not be followed. Note that
the Modelling Lamp indication is relative slow compared to the normal LED and Sounder
indication which means that the unit will actually be ‘READY’ and may, if required, be flashed
before the sequence is complete.
AUTO-DUMP Operation
‘AUTO-DUMP’ automatically discharges the capacitors when the power is reduced. The ‘READY’
indicator flashes while the unit is dumping. The user may select one of two DUMP methods by
means of the ‘OPTIONS’ sub-menu. See ‘OPTIONS’ for a description of how to access this
mode.
The default factory setting is ‘
Fd.0
’. In this mode the unit resistively dumps excess energy
whenever the flash setting is reduced. This is a relatively slow method and can take several
seconds to reach the required value if the change is large. Use the ‘TEST’ button to manually
flash dump the excess energy quickly if required.
The optional mode is ‘
Fd.1
’. The unit attempts to automatically reduce the power to the desired
setting in the shortest possible time. It does this by determining how long it would take to simply
resistively dump the excess stored energy compared with flash dumping and then having to re-
charge to the new setting.
To prevent multiple flashes occurring while the setting is being changed the unit waits until the
‘DOWN’ button is released before deciding whether or not to flash. The result is that small or slow
decreases in the flash setting are unlikely to cause the unit to flash.
The unit is designed to automatically flash, if possible, when turned off. The resistive dump will
continue to reduce any remaining energy while the unit is off. This safety feature cannot be
disabled.
INFRA-RED REMOTE CONTROL
The unit has a built in receiver for the optional Infrared Remote Control Transmitter. Switch the
Infrared Remote Receiver on or off using the ‘REMOTE’ button. IR Remote Control is enabled
when the associated LED is lit.
‘C’ - REMOTE CONTROL CHANNEL Display Mode
When the IR Remote is switched on the unit will automatically enter the ‘CHANNEL’ display mode
to allow adjustment. The ‘
C
’ before the displayed value indicates this mode:

CXX
0 - 12
Display IR Channel number. Use ‘UP’ or ‘DOWN’ to select.
If no adjustment is attempted within 4 seconds then the display will revert to the default ‘FLASH’
mode. If the value needs to be reviewed or adjusted later then use the ‘FUNCTION’ button to
select the ‘CHANNEL’ display mode.
IR REMOTE Operation
The following assumes that ‘REMOTE’ has been switched on. The selected channel number has
the following significance:

Causes ALL units, within range, to respond to the Transmitter
regardless of the individual unit channel number.
All functions except ‘REMOTE’ On/Off can be controlled remotely. This allows the units remote
control channel number to be changed using the current channel. The new channel number is
only activated after the displayed ‘
C
’ function times out. Use this facility with care since remote
control of an individual unit could be lost, requiring the Channel number to be manually reset on
the unit.
