NOTE: Setup mode allows you to select between alkaline and Ni-Cd batteries. The two types of batteries have unique low battery alarm characteristics. To prevent unexpected low battery alarms, always make sure the battery type setting in Setup mode matches the type of batteries installed in the Eagle.

Replacing Sensors

Electrochemical sensors (O2, H2S, and CO) gradually deteriorate,

regardless of use, and require periodic replacement. Combustibles sensor life is typically related to usage, but certain conditions may affect duration.

The Eagle sensors are easy to replace but do not contain user- serviceable components. For genuine RKI sensors, call RKI or your local distributor. All sensors are covered by a limited warranty; see warranty for details.

CAUTION:Avoid pulling on sensor wires. Always unplug at the connector.

Replacing the combustibles sensor

Replace the combustibles sensor when:

•The combustibles channel cannot be calibrated correctly.

•The LEL reading cannot be set to 0 by the Demand Zero command.

To replace the combustibles sensor:

1.Take the Eagle to a non-hazardous location, and turn the power off.

2.Unscrew the two large screws on the top of the case, then carefully lift the top of the case and lay it aside.

3.Unplug the four-wire connector (red/white/green/black) from the circuit board.

4.Locate the combustibles sensor. With the batteries closest to you, the combustibles sensor is at the top left corner of the sensor block.

5.Remove the two screws in the oval keeper plate, and remove the sensor from the sensor block.

6.Unplug the cable socket from the top of the sensor. Retain the oval keeper plate for use with the replacement sensor.

7.Install the replacement sensor in reverse order.
