6 PREVENTIVE MAINTENANCE

The transmitter/sensor unit should be brushed or wiped clean once a year or more, of any dust

or dirt which settles on it, depending on the accumulation.

The unit SHOULD NOT be submerged in water or other liquids.

conditions that could cause a liquid to enter the enclosure should be avoided.

To verify the operation of the transmitter/sensor unit, make sure that is still responding to gas.

This test should be performed every few months, but for more demanding applications,

verification should be performed on a weekly basis.

CAUTION:

TURN OFF THE POWER BEFORE ATTEMPING THE FOLLOWING.

Sensor life is typically > 5 years. The sensor should be replaced under the following conditions:

1. When the sensor element becomes an open circuit, the transmitter outputs a fixed 1 mA

signal.

2. When the sensor no longer responds to the presence of gas or has an unstable zero

signal.

When the sensor needs replacing, reorder the "Sensor Part Number" listed in Product

Information, page iv. See Figure 6 for sensor replacement.
