Supply Does
not work
3. Fuse is burned.
No laser emission when
manual test.
Contact with us for
repair.
AC power on
but no laser
emission
1. Control wire
connected wrong
Check if wire is connected
correctly according to
Operation Instruction
Rewiring correctly
2. Internal
connector is loose.
Open outside case and
check
Tighten connector.
3. Protection switch
on but on water
through or water
through switch is
broken.
Voltage>0.5V between
“WP”and”G”
Water through or
change water
through switch.
4. Wrong output
laser signal
Voltage between”TH ”
and “G” should<3V when
When laser-open
controlled by high level
Replace CNC card or
change GND.
Voltage between"TL" and
“G” should>3V when
laser-open controlled by
low level.
5. Power control
signal is 0.
Voltage between “IN”and
“G” is 0.
Increase voltage
between “IN”and “G”.
6. Fuse is burned. Fan does not work
Send back factory for
maintenance
7. Others
Send back factory for
maintenance
Laser
emission at
all times
1.When “TL” control
laser: short circuit
between”TL ”and
“G”.
Voltage between”TL ”
and “G” =0
disconnected
between”TL ”and
“G”.
2. Circuit is broken.
Send back factory for
maintenance
3. Switch of manual
test laser emission is
broken.
Change switch of
manual test laser
emission.
4. Other causes.
Send back factory for
maintenance
Current is
not
increased
1. AC voltage is too
low
Output current is always at
5mA around.
Use AC voltage
regulator.
Send back factory for
maintenance
2. Power supply
and laser Device is
not connected very
well
3. Power control
signal from CNC
card is not
connected very well
with “IN”.
Output current is always at
10mA around.
Re-connected
3. Potentiometer of
power is broken.
Output current is not
stable.
Change
potentiometer.
4. PWM frequency
or amplitude is not
suitable.
Change PWM
frequency or
amplitude.
