This Section provides service diagnostics for the Merlin 3000 Power Supply, allowing the Technician to islolate any faulty Subassemblies. Refer to Section 5, Repairs & Replacement Procedures, for parts replacement instruc- tions.

Under no circumstances are field repairs to be attempted on Printed Circuit Boards or other Subassemblies of this unit. Evidence of unauthorized repairs will void the fac- tory warranty.

NOTE

The troubleshooting contained in this manual is for the Merlin 3000 Power Supply only. Trouble- shooting other parts of the system is covered in the separate manuals for that product.

4.02Periodic Inspection & Procedures

NOTE

Refer to Appendix XV for a recommended mainte- nance schedule for water cooled plasma cutting systems.

This subsection describes inspection procedures which should be performed at periodic intervals as required.

A. Fan Motor and Pump Lubrication

The fan motor and pump in the power supply should be oiled twice per year or once for each 100 hours of operation. To oil the motor, remove one side panel and add two or three drops of 20 SAE oil to the front and rear oil holes on the motor.

NOTE

Some units may utilize a sealed motor design which does not require lubrication.

B. Routine Maintenance

The only other routine maintenance required for the power supply is a thorough cleaning and inspection, with the frequency depending on the usage and the operating environment.

To clean the unit, first make sure that the power is disconnected. Remove the side panels and blow out any accumulated dirt and dust with compressed air especially from the radiator. The unit should also be wiped clean. If necessary, solvents that are recom- mended for cleaning electrical apparatus may be used.

While the side panels are off, inspect the wiring in the unit. Look for any frayed wires or loose connections that should be corrected.

C. Coolant Filter Assembly (Rear Panel)

The rear panel filter screen should be cleaned peri- odically. Remove the filter screen by unscrewing the filter holder from the Coolant Filter Assembly. Clean the filter screen by rinsing with hot soapy water. Re- move soap residue by rinsing with clean hot water. Be sure that all the soap has been removed and the screen is dry of water before re-installing in the Cool- ant Filter Assembly.
