Figure 6-3 Removing a Sensor from the Innova
NOTE
Figure 6-2 illustrate sensor assignments for the standard Innova. The
sensor assignment for your Innova may be different depending on the
Innova model you are using. For models that have less than four
sensors, empty sensor cavities are filled with sensor plugs.
4. Disconnect or unplug the sensor’s connection to the Innova.
CAUTION
If you use a tool to loosen the sensor from the flow block, be
careful not to damage the sensor housing or the flow block.
5. Using your fingers, tilt the sensor from side to side to loosen it, then
pull the sensor straight out of its flow block cavity, see Figure 6-3.
6. Insert the replacement sensor into the cavity, then apply downward
pressure on top of the sensor until it is firmly seated in the cavity. For
toxic sensors, make sure not to bend or damage the sensor pins.
7. Reconnect the sensor’s connection to the Innova main board.
For the combustible gas sensor
, connect the purple, white, and red
wires to the proper terminals (
P
,
W
,
R
) on the terminal block (
TB1
).
For the remaining sensors
, plug the sensor wire connector into the
applicable socket (
OXY
,
TOX1
, or
TOX2
).
