III. Operation Instruction
1. Laser Tube Connection:
(Referring to Power Supply and Laser Device's Connection
Diagram)
High voltage terminal (HV+) of MYJG-40NW power supply should be connected to the
positive pole of CO2 laser device. Current circuit of the power supply shall be connected
to negative pole (laser output terminal) of laser device, through an ampere meter or
directly.
2. Connection of Control Signal
The control signal shall be reliably connected to control terminal of the power supply
MYJG-40 NW, after connecting the DAC output signal and TTL signal of external
computer with the power supply, the laser device shall work as expected. If the laser lamp
can not work properly, should check the control signal is correct or not(include check the
voltage specification and logic), if use PWM control as power control, make sure f≥20KHz,
amplitude (peak value) ≤5V, Check and make sure protection switch WP connection is
correct at same time.
3. Voltage of Power Input:
MYJG-40W's power input of the power supply shall be 220VAC/50Hz. This power
supply can be adjusted for 110V or 220V.
4. Others:
A group of protection switches are also reserved for detection of water switch, fan
switch, open-enclosure protection and so on.
Caution:
1) Water cooling system should be working properly when switching on laser device.
2) Circuit of high voltage output should not be open! [High voltage output terminals
(positive and negative poles) shall be properly connected to positive and negative
poles of laser device, respectively.]
3) Attentions should be given to avoid any electric shock after the power supply being
switched off. (The
Insulation Safety Requirements
should be 40KV between the
terminal of output and "G")
4) Well-grounded three-pole receptacle should be used to the supply power. The
enclosure should be well grounded to avoid electric shock.
