CHAPTER 15 FPS-S1U MAINTENANCE

15.1 Introduction

This chapter contains information about maintenance, calibration and troubleshooting of the FPS-S1U rack.

15.2 Units under warranty

Units requiring repairs during the warranty period should be returned to Densei-Lambda authorized service office. Unauthorized repairs performed by other than the authorized service facilities may void the warranty.

15.3 Periodic maintenance

No routine maintenance of the FPS-S1U rack is required except for periodic cleaning. To clean, disconnect the unit from the AC supply and allow 30sec. for discharging internal voltage. The FPS-S1U should be cleaned using 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 hydrocarbons or chlorinated solvents for cleaning. Use low pressure compressed air to blow dust from the unit.

15.4 Adjustments and Calibration

No internal adjustment or calibration are required. Units that are returned for repair will be calibrated at the service office In any case ,opening the cover is not allowed.
