7-1. Periodic maintenance for the EXA 402 converter
The EXA transmitter requires very little periodic maintenance. The housing is sealed to
IP65 (NEMA 4X) standards, and remains closed in normal operation. Users are
required only 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 pushbuttons. If the window
becomes soiled, clean it using a soft damp cloth or soft tissue. To deal with more
stubborn stains, a neutral detergent may be used.
NOTE
Never used harsh chemicals or solvents . In the event that the window becomes heavily
stained or scratched, refer to the parts list (Customer Maintenance Parts List) for
replacement part numbers.
When you must open the front cover and/or glands, make sure that the seals are clean
and correctly fitted when the unit is reassembled in order to maintain the housing’s
weatherproof integrity against water and water vapor. The measurement otherwise may
be prone to problems caused by exposure of the circuitry to condensation.
