Standard Delta F Oxygen Cells
Figure 20 below shows a standard Delta F Oxygen Cell and identifies the sensing and secondary electrodes. Make
oxygen cell connections from the electrodes on the oxygen cell to the
moisture.IQ. Refer to Figure 18 on page 22 and Table 2 below for the required connections.
IMPORTANT:
To maintain good contact at each terminal block and to avoid damaging the pins on the connector, pull
the connector straight off (not at an angle), make cable connections while the connector is away from
the unit, and push the connector straight on (not at an angle) when the wiring is complete.
Note: The temperature reading of the sensor is used for internal temperature compensation and does not require any
user setup.
