Warm-Up - Occurs after the lamp ignites and ends when the lamp has
warmed to operating temperatures. The lamp fans are held off and the
unit goes to high power. Due to the technology of the power supply, the
units do not draw large amounts of current during warm-up. Due to the
restrictive cooling, the lamps warm up rapidly, without surge current.
The shutter will not open until the unit reaches temperature.
Idle - Between exposures, the lamp is held in idle. During this period,
the lamp fans vary in speed to maintain the proper lamp temperature.
This allows the unit to consume less power on idle, and provides a wider
range of exposure capabilities, since this same low power level is available
for exposures. The lower idle saves power, generates less heat, and extends
the lamp life.
Expose - The units allow exposures at three levels. At high power, the
high and medium relays are activated. At medium power, the medium
relay is activated.
Cool-Down - When the unit is switched off, all fans are turned on to
cool the equipment. After the cooling period, the unit disables all of its
functions until it is started again.
Trigger - If the lamp is turned on before the unit has fully cooled, the
fans will run at full power and a trigger pulse is created. This mode will
release itself when the lamp strikes. The unit is responding to conditions
to provide these functions. It is therefore not possible to confuse the unit.
If there is a momentary loss of power, the unit will cool the lamp until it
strikes. It is recommended that the unit be shut off and allowed to cool,
rather than turning off the power supplied to the unit.
