CHAPTER 1: SYSTEM DESCRIPTION
LW500A/LW600A PULSED Nd:YAG LASER
1-4 990-539
3 REMOTE INTERLOCK Connector. Used to connect the Laser to the Remote Interlock circuit for
safety. When disconnected (opened), the main (resonator) shutters close to prevent laser emission.
4 RS-485 (2) Connector. For external communications (optional).
5 RS-485 (1) Connector. For external communications (optional).
6 Power Supply Terminals. If you open the front door, you will see the power input terminals.
Connect the terminals to a 3-phase power supply of 200/220/240
VAC or 380/400 VAC. To ensure
safety and optimal operation, the laser must be properly grounded. A Neutral connection is not
required or used on this Laser. However a PE (protective earth) Ground is provided and MUST be
used. It is important to note that the Neutral and PE Ground are NOT the same. DO NOT connect
the Neutral line to the PE terminal.
7 Drains. For draining water from the secondary cooling water tank in order to prevent damage from
freezing conditions.
8 Water Filter. Removes dirt and other contaminants from the secondary cooling water.
9 Ion-exchange Resin (Deionizer). Used to deionize the secondary cooling water.
10 Water Level Label. Shows proper level of the secondary cooling water.
11 Cooling Water Tank. Holds secondary cooling water used for cooling the Nd:YAG rod, flashlamps
and the electronics.
