REPLACING FAULTy SENSORS
Installing Multiple Replacement Sensors
When circumstances indicate the need to replace multiple
sensors on the same unit in the eld, it is recommended
to replace all sensors to ensure the system regains its full
robustness and functionality. Replacing system sensors requires
the following actions:
1. Acquire the needed number of new, unused replacement
sensors su󰀩cient to replace all sensors. Do not attempt
to used previously installed sensors, as the MT6210
may not be able to properly address these sensors for
replacement.
2. Remove power from the controller/network.
3. Access all refrigerant sensors, disconnect them from the
factory wiring harness, and remove the sensors from the
sensor mounting brackets. Dispose of the old sensors
properly.
4. Determine the location for sensor #1. This location will be
clearly marked in the unit.
5. Install the new #1 sensor onto the sensor mounting bracket
and connect the sensor to the factory wiring harness.
Ensure this is the only sensor connected to the
network.
6. Apply power to the controller/network, allow the controller
to nish the start-up time, and observe the network status
summary on the display.
7. Conrm the network summary indicates the successful
discovery of sensor #1, S01=1.
8. Remove power from the controller/network and determine
the location for sensor #2. This location will be clearly
marked in the unit.
9. Install the new #2 sensor onto the sensor mounting bracket
and connect the sensor to the factory wiring harness.
Ensure that sensor #1 is still connected to the network.
10. Apply power to the controller/network, allow the controller
to nish the start-up time and observe the network status
summary on the display.
11. Conrm the network summary indicates the successful
discovery of sensor #1, S01=1 and sensor #2, S02=1.
12. Continue this process sequentially for the remaining
sensors, ensuring that previously installed new sensors
remain connected to the network and conrming
successful discovery after each subsequent sensor is
installed.
13. Once all sensors have been installed and successfully
addressed in the unit, normal operation can be resumed.
