Power On/Off - Hamamatsu Photonics LIGHTINGCURE LC8 Instruction Manual

■ Power On/OFF
Press the upper part of the power switch to turn on the power.
Immediately after the power is turned on, initialization of the equipment is executed. It takes about 10
seconds and during this time, all indicator lamps light up and no button operation or external control is
accepted.
The state upon completion of initialization is as follows due to the power on reset function.
This state is called the "stand-by state"
To turn off the power, press the lower part of the power switch.
Caution
● At the end of using the unit, be sure to run the cooling fan for approx. 10 minutes after turn-
ing off the lamp to cool inside of the unit and then turn off the power.
● Functions at momentary power failure
When the power supply is shut off for some time due to a momentary power failure or for any rea-
son, the way to return to the normal state varies depending on the power failure duration time.

Power ON/OFF

• The lamps are turned off.
• The shutter is closed.
• When the power failure time is 30 ms or less
The lamp remains on. Everything functions normally.
• When the power failure time is about 1 second
The lamp goes off and both of the lamp ON signal and lamp stable signal turn off temporarily as
well. After the power is supplied again, the lamp ON system functions automatically to turn on the
lamp again. At this time, if the shutter was open before the power failure, it is forced to close for
the sake of safety. When timer irradiation or program irradiation is used, it is reset after the power
is supplied again. After the lamp turns on again, the lamp ON signal is output and about 10 sec-
onds later the normal function is restored. In this state, the unit is usable.
• When the power failure time is 2 second or more
The lamp goes off. After the power is supplied, the power on reset function is activated to cause
the lamps to turn off and the shutter to close.
To restore the normal state, it is necessary to recheck the lamp by inputting the lamp ON signal
from outside. 5 minutes after the lamp turns on, the lamp stable signal is output and the unit be-
comes usable. (just like when it is used in the normal state)
