5.0 MAINTENANCE
No periodic maintenance is required for the Teledyne Model LXT-
380 Transmitter.
Do not open the LXT-380 enclosure in a hazardous environment
without ensuring that NO hazardous gases, vapor or dust is present.
Remove power prior to opening cover and/or performing any service,
repair or cleaning.
When you open the front cover and/or cable glands, make sure that
the seals are clean and correctly fitted when the unit is re-assembled in
order to maintain the housing’s NEMA 4X weatherproof integrity
against water and water vapor.
5.1 CLEANING
The Model LXT-380 transmitter requires no periodic maintenance,
except to make sure the front window is kept clean in order to permit a
clear view of the display and allow proper operation of the navigation
buttons. If the window becomes soiled, clean it using a soft damp cloth
or soft tissue. To deal with more stubborn stains, a neutral detergent or
spray cleaner like Windex may be used. Never use harsh chemicals or
solvents.
5.2 REPAIR/SERVICE
Repairs on LXT-380 transmitter components may be accomplished
only after declassifying the area and assuring that NO hazardous
environment exists. Additionally, the power supplying the transmitter
shall be de-energized.
Replacement of components may only be accomplished by
replacing the complete three (3) circuit board assembly with similar
parts. No board-level components are serviceable and shall be returned
to the manufacturer for repair.
