7. Assure the keyway registration of the female plug on the cable and male receptacle on the sensor match up.
8. Push the female plug (including the knurled lock nut) molded to the cable into the male receptacle attached to
the new sensor.
9. Screw the knurled lock nut attached the cable onto to the male connector attached to the sensor, tighten
finger tight plus ¼ turn.
10. Replace the front cover of the monitor and ensure that the gasket is replaced as well to maintain CE approval
and NEMA 4 rating.
11. Tighten the four (4) screws to secure the front cover.
12. Connect the gas lines, vent line first, as previously described.
13. Proceed to calibration.
Remote Oxygen Sensor:
Applications requiring the sensor to be located remotely from the electronics dictate the separate packaging and
shipment of the electronics enclosure, oxygen sensor and sensor flow housing. The appropriate length of cable to
connect the sensor to the electronics is supplied and connected to the electronics. To install the remote sensor:
1. Locate Item #3 sensor mounting bracket, note the through holes and identify the surface for installation.
2. Using two (2) 6/32 screws of the appropriate type and length secure the sensor mounting bracket to a flat
surface, the position illustrated below left is recommended for optimum performance.
3. Remove the oxygen sensor from the bag. Do not remove the shorting device (wire loop) from the sensor.
4. Position the threaded end of the sensor into the U-shaped opening of the sensor mounting bracket.
5. Screw Item #6 sensor retaining nut onto the threaded end of the oxygen sensor, finger tighten to secure.
6. Remove the shorting device (wire loop) from the receptacle located at the rear of the sensor. Minimize the time
the sensor is exposed to ambient air.
7. Assure the keyway registration of the female plug on the cable and male receptacle on the sensor match up.
8. Push the female plug (including the knurled lock nut) molded to the cable into the male receptacle attached to
the new sensor.
9. Screw the knurled lock nut attached the cable onto to the male connector attached to the sensor, tighten
finger tight plus ¼ turn..
10. Refer to the Calibration Gas Connections above and proceed to calibration.
