Measures
14 SIMMER TROUBLE OFF ON
Flashlamp is not turned on.
Check the flashlamp for malfunction.
If faulty, replace it. Resistivity of the
secondary cooling water may below.
Referring to 13, take measures for the
secondary cooling water.
15 CHARGE TROUBLE OFF ON
Too much time is required to charge the
capacitor in the laser power supply or the
charged voltage is too high.
Check if the capacity of the power supply
or power cable is insufficient.
Check the fuse in the power supply.
If it is blown, replace it.
16 BANK ALARM OFF ON
This signal is output when a trouble of
undercharge, over-charge, no-voltage
or over-voltage of capacitor in the power
supply of the Laser occurs. In this case,
consult us.
18 MAIN SHUTTER TROUBLE OFF ON
A laser start signal is input while the
resonator shutter is moving.
Extend the time from input of resonator
shutter operating signal to input of laser
start signal. If the trouble will continue even
after the above measures, consult us.

BRANCH SHUTTER 6 TROUBLE
OFF ON
A laser start signal is input while the branch
shutter is operating.
Extend the time from input of beam select
signal to input of laser start signal. If the
trouble will continue even after the above
measures, consult us.

DISCHARGE UNIT
OVERCURRENT
OFF ON
Lamp or discharge unit (power transistor
component, CT) fault.
If trouble will continue even after the lamp
has been replaced, consult us.
29 DISCHARGE UNIT TEMP OFF ON
Check discharge unit for absence of the
secondary cooling water; and fan motor on
the rear for not running.
30 DISCHARGE UNIT OVERPOWER OFF ON
Laser oscillation efficiency lowered.
This may be due to the expired service
life of the lamp, deviation of oscillation,
contaminated YAG rod or mirror, or
failure of the sensor unit. If the trouble
will continue even after lamp has been
replaced, consult us.
31 BRANCH UNIT COVER OPENED OFF ON
The branch unit cover plate is removed, or
its mounting screws are loosened.
Secure the cover plate with the screws.
