MAINTENANCE

As with any device based on solid-state electronics, actual maintenance of the RTU

should be minimal. However, there are certain guidelines that, if followed, will minimize

device failure and increase the product's service life.

ENCLOSURE MAINTENANCE

Enclosure maintenance is a program of routine inspections to ensure the integrity of the

lid's seal and the various ports in the enclosure's exterior. Excessive moisture can ruin

an RTU if allowed to accumulate within the enclosure. Although the circuit boards

themselves are conformally coated to protect against humidity, the wiring

interconnections and various exposed metal surfaces are susceptible to corrosion in

extreme cases of interior humidity. Here are some checks you should periodically make

of the enclosure:

1. Ensure that the mounting arrangement for the unit is secure and provides a stable

platform for termination of the pressure tubing.

2. Verify the integrity of the enclosure lid seal. Check the lid gasket for deterioration,

chemical damage, tears, or compression.

3. Check for damaged cord grips and a missing or damaged RS-232C port cap.

4. Verify the integrity of the enclosure lid seal. Check the lid gasket for deterioration,

chemical

damage, tears, or compression.

5. Check for damaged cord grips and a missing or damaged RS-232C port cap.

6. Examine the RS-232C port itself. Ensure that the port's mounting screws are secure

and

provide firm support when attaching a serial cable.
