This Chapter provides information about maintenance, calibration and troubleshooting.
9.2.
Units Under Warranty
Units requiring repair during the warranty period should be returned to a TDK-Lambda
Americas Inc. authorized service facility. Refer to the addresses listing on the back cover of
this User’s Manual. Unauthorized repairs performed by other than the authorized service
facilities may void the warranty.
9.3.
Periodic Maintenance
No routine maintenance of the power supply is required except for periodic cleaning. To
clean, disconnect the unit from the AC supply and allow 30sec. for discharging internal
voltages. The front panel and the metal surfaces should be cleaned using a mild solution of
detergent and water. The solution should be applied onto a soft cloth, and not directly to
the surface of the unit. Do not use aromatic hydocarbons or chlorinated solvents for
cleaning. Use low pressure compressed air to blow dust from the unit.
9.4.
Adjustments and Calibration
No internal adjustment or calibration is required. There is NO REASON to open the power
supply cover.
9.5.
Parts Replacement and Repairs
As repairs are made only by the manufacturer or by authorized service facilities, no parts
replacement information is provided in the manual. In case of failure, unusual or erratic
operation of the unit, contact a TDK-Lambda Americas Inc. sales or service facility nearest
you. Please refer to the TDK-Lambda Americas Inc. sales offices addresses listing on the
back cover of this User’s Manual.
9.6.
Troubleshooting
If the power supply appears to be operating improperly, use the Troubleshooting Guide
(Table 9-1) to determine whether the power supply, load or external control circuit are the
cause.
Configure the power supply for basic front panel operation and perform the tests of Section
3.8 to determine if the problem is with the supply.
Table 9-1 provides the basic checks that can be performed to diagnose problems, with
references to Sections of this User’s Manual for further information.
