Series XT-50, XT-80, and XT-100 Amplifiers Maintenance and Service 4-1
CHAPTER 4: MAINTENANCE & SERVICE
Preventative Maintenance
Periodically the exterior of the amplifier should be inspected and cleaned. The
inspection should include:
1. The integrity of the mounting bolts. Tighten as necessary.
2. The integrity of the output waveguide flange mounting bolts. Tighten as
necessary.
3. The integrity of the input connections and the interconnecting cables.
4. The air inlet and exhaust ports. Make sure that there is no debris such as
insect nests, leaves, straw, etc. that obstruct the air inlet ports. Use high
pressure air to blow dust and debris out of the Lower Deck cover.
Depending upon the operating environment, and at least annually, the Lower
Deck Cover should be removed per the procedure presented later in this chapter.
Inspect the cooling fins for accumulated dirt and debris. Use high pressure air to
blow dust and debris out of the Lower Deck cover. After completion of the cleaning
operation, check the integrity of the Electrical connections and then replace the
Lower Deck cover.
Remove Lower Deck Cover
Proceed as follows:
a Disconnect prime power from the amplifier (Connector J2).
b. Remove the 12 #6-32 self-locking mounting screws. Save the screws for
reuse.
c. Remove the Lower Deck cover and disconnect the cable from the cover’s EMI
filter.
