sensor if necessary.
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. In the front half of the bottom case, locate the sensor you want to
replace. The sensor with wires connected to EC3 on the analog
PCB displays its reading on the third line of the screen. The sensor
connected to EC4 on the analog PCB displays its reading on the
fourth line of the screen.
4. Remove the two screws at the base of the bracket.
5. Lift the sensor assembly up enough to remove the flow adapter
(two screws). The flow adapter is attached to the sensor.
CAUTION: Avoid pulling on sensor wires. Always unplug at the connector.
6. Disconnect the connector from the analog PCB. Note to which
socket (EC3 or EC4) the connector is connected.
7. Remove the sensor assembly from the instrument case.
8. Remove the two screws that secure the sensor assembly to the
bracket.
9. Remove the two screws that secure the sensor to the amplifier,
then remove the sensor from the amplifier. Retain the amplifier for
use with the replacement sensor.
10. Install the replacement sensor in reverse order.
NOTE: Allow up to 4 hours after you replace a non-standard toxic
gas sensor, or if charged batteries have not been installed for
an extended period, for the channel to show a normal
response, then calibrate the sensor.
