3 Maintenance

3.1 Periodic Maintenance

It is essential that the test and calibration schedule be adhered to. Honeywell Analytics recommends the following maintenance schedule:

•Response test prior to each use. Expose sensor to a sample of the target gas to verify proper sensor response and alarm functions.

•Calibration should be performed with certified calibration gas every six months, and all tests must be logged.

•Check filter material every six months. Replace if dirty or moist.

•If the optional sensor keeper is used for extra SMART-CELLs, change the sensor keeper battery once every 6 months. Use only alkaline “D” size batteries.

3.2Sensor Life

The electrochemical SMART CELL is extremely reliable, but the following can cause the cell chemicals to become depleted:

•A period of time

•Exposure to high temperatures

•Exposure to high concentrations of the target gas

•Exposure to high moisture

When the cell becomes depleted, the unit will give no indication of failure other than that the sensor will not respond. For this reason it is absolutely essential that these units be exercised with a gas sample on a regular basis.

Typical sensor life under normal use is two years or more.When the SMART-CELL will no longer calibrate properly, simply purchase a new SMART-CELL and replace.

3.3 Calibration

Calibration is recommended every six months in normal use. Each SMART-CELL stores its calibration and alarm setpoint information on its own memory chip. When the SMART-CELL is plugged into the Honeywell EC-P2, this information is used by the sensor. The SMART-CELL can be field calibrated by the user or returned to Honeywell Analytics for factory calibration.

The calibration procedure requires the use of a bypass tee to allow the gas to be drawn into the flow cell without creating variable pressure or dilution problems. Calibration gas cannot be fed into the flow cell under pressure.

When applying calibration gas use the bypass tee as shown in Figure 4 on page 11. The flowrate of calibration gas should be high enough that at least 0.5 SCFH is flowing out of the calibration tee. This can be measured with the supplied flowmeter and insures that air is not being drawn into the unit and diluting the calibration gas.
