(4) Check the outsides of units installed in the oscillator as follows:
Check items
1 Check whether any printed circuit boards are loose or removed.
2
Check whether any cables are damaged (such as damaged
sheathing).
3 Check whether any connectors are loose or detached.
4 Check that the discharge tubes are neither cracked nor damaged.
5
Check that the turbo blowers and other units are neither loose nor
missing.
6
Check that the power supply units and matching boxes are neither
loose nor missing.
7 Check that the input unit is neither loose nor missing.
8
Check that the connection to the electrode of each discharge tube is
not loose.
9
Check whether any fittings part of the water piping and gas piping is
loose.
10 Check all screw terminals in the units.
11
Check the oil level in the turbo blowers, and check for oil
contamination. (See Subsection 4.3.1 for details.)
12
Check the oil level in the exhaust pump, and check for oil
contamination. (See Subsection 4.3.2 for details.)
(5) Connect the power and signal lines to the oscillator. (See
Subsection 3.2.3 for details.)
Check items
1 Oscillator power cable
2 Grounding cable (class 1 grounding)
3 Signal cable between the CNC and oscillator (or optical fiber)
4 Signal cables
5 Exhaust pump power cable (C1000-E only)
(6) Check the input power supply voltage, frequency and phase
rotation. (See Subsection 3.3.1 for details.)
Also set the frequency of the power supply to the hour meter.
(7) Check the setting of communication jumper pin LINK1 on the IF
PC board. (See Subsection 3.3.1 for details.)
If the communication cable is a metallic cable, insert the jumper
pin LINK1 into JD1; if the communication cable is an optical
fiber cable, insert the jumper pin into the COP side.
(8) Connect the laser gas and cooling water pipes. (See Subsections
3.2.1 and 3.2.2 for details.)
Check items
1
Check the laser gas composition and purity (check whether the
specifications are satisfied).
2 Check the laser gas piping status.
3
Check that there is no gas leakage in the external piping between the
gas cylinder and oscillator.
4
Check the quality of the cooling water (use of tap water passed
through an ion exchanger).
