Chapter 5 Maintenance and Troubleshooting
5.1. Maintenance of the LDS5 Power Supply
5.1.1.
Setting the LDS5 AC Line Voltage
The operating AC voltage is indicated by the value shown in the small gray window
located below the AC receptacle. The CPS11K systems are shipped with the
operating AC voltage set to 120 VAC, while the CPS11K-EC Metric versions are
shipped with the operating AC voltage set to 230 VAC. If this needs to be changed,
follow the instructions below:
1. Make sure the LDS5 is turned off, and remove the AC line cord.
2. Slide the voltage selector (located underneath the AC input receptacle)
to the appropriate line voltage (115V or 230V), using a small screwdriver.
3. Verify the correct voltage is shown through the window; if not, repeat the
above steps.
5.2. Troubleshooting
The CPS11K(-EC) is a robust system which should provide many hours of reliable
service. There are no user-serviceable parts inside the system. If there appears to
be a problem with the unit, please contact your local Thorlabs’ Technical Support
Office and a technician will be happy to assist you.
