two quick release fixings, push the sensor mounting out of the sensor
plate housing, taking care to retain any seals.
Installing or replacing an i-module
If replacing an i-module with one of the same type, instrument specific
configuration will be retained. If replacing with a different i-module its default
configuration will be loaded.
1.
Unwrap the i-module from any packaging, ensure the sensor is fully
seated on the module board.
If you are installing a new i-module into a currently unused slot, you
will first need to remove the dummy i-module. Follow the i-module
removal instructions to do so.
2.
Ensure the gasket is in place on the sensor, push the sensor through
the sensor aperture in the sensor plate housing. Click the quick release
fixings around the i-module board, ensuring the i-module is held in
place firmly and the sensor is still tightly located on the module board.
Replace the retaining ring on the clips.
3. Attach the ribbon connector by squeezing the two retaining lugs , on the
module board, toward each other and pulling out slightly. Slide the ribbon,
with the metal connectors facing away from the board, into the slot. Push
the retaining lugs back toward the sensor, this will grip the ribbon firmly.
Warning
Do not twist the connection ribbons.
Do not pull the sensor housing assembly too far from the PCB board.
Doing so may damage the cabling or electrical connections.
Re-assembling the Tetra unit
1.
Ensure the connection ribbons and cables are tucked in. Slide the

identified.
