Measures
01 POWER SUPPLY COVER OPENED OFF ON
The side cover or rear cover is removed or
their mounting screws are loosened.
Secure the covers with the screws.
02 HEAD COVER OPENED OFF ON
The head cover or lamp replacing cover is
removed.
Mount them.
03 EMERGENCY STOP OFF ON
An emergency stop signal is input. Close
the Pin No.2 and Pin No.7 of the EXT.I/O (3)
connector or the EXT.I/O (4) connector.
Reset the EMERGENCY STOP buttons
provided at the front surface of the main
unit and of the laser controller.
04 COOLANT LOW LEVEL OFF ON
Secondary cooling water volume is
insufficient.
Add cooling water. If the equipment is
swayed, the coolant level may change.
Stabilize the equipment.
06 OVERHEAT OF PUMP OFF ON
The cooler pump is overloaded.
Check whether the cooling water route is
abnormal.
08 DISCHARGE RESISTOR TEMP OFF ON
Frequent repetitions of HV-ON/OFF may
cause this trouble.
Wait for a while till the discharge resistor
cools; press [TROUBLE RESET]. When
this alarm is not reset even after the above
measures, consult us.
10
HIGH TEMPERATURE OF
COOLANT
OFF ON
Primary cooling water flow rate is low or
the cooling water temperature is too high.
→ P.73
Increase the primary cooling water flow
rate. Check if the cooling water circulates
normally.
11
LOW TEMPERATURE OF
COOLANT
OFF ON
The temperature of the secondary cooling
water is too low. → P.73
If the ambient temperature is low, it takes
time to raise the secondary cooling water
temperature. Wait until the secondary
cooling water temperature rises after the
power is turned on.
12 LOW FLOW RATE OF COOLANT OFF ON
The secondary cooling water flow rate is
low. The wire net in the oscillator or the
water filter is clogged.
Dust off the wire net or the water filter, or
replace the water filter.
13
DEIONIZE TROUBLE
(****MΩ•cm)
OFF ON
Purity of the secondary cooling water is
low.
Allow the cooler to operate for 50–60
minutes. If this trouble still occurs, replace
the ionexchange resin.
