To restore communication between the master controller and the CoreSense module in your Emerson Air Conditioner, try reversing the polarity. This should re-initiate the communication process.
What to do if my Emerson CORESENSE shows a communication error?
If you are experiencing a communication error with your Emerson Air Compressor, it could be due to a loss of communication between the CoreSense™ control module and the rack controller. Check if there is a communication network. If not, set the network dip-switch to 'stand-alone' and press reset. Alternatively, the communication loss could be between the CoreSense™ control module and the sensor module. In this case, verify that the communication harness is properly connected to both the CoreSense™ module and the sensor module.
Why does my Emerson CORESENSE have a missing phase?
A missing phase in your Emerson Air Compressor could be due to loose wiring connections at the terminals inside the compressor T-Box. Verify the voltage supply from the main power buss to resolve this issue. Another cause could be worn-out contactors. Verify the voltage into and out of the contactor, and repair or replace the contactor if necessary.
What to do if my Emerson CORESENSE Air Compressor has a locked rotor?
If your Emerson Air Compressor's motor rotor is mechanically seized, verify that the motor voltage is adequate, remaining within +/- 10% of the nominal rated voltage, especially during the starting event.
How to fix connection lost between CT and sensor in Emerson CORESENSE?
If the connection between the CT and sensor is lost in your Emerson Air Compressor, here are a few things to check: * First, verify that the CT connector is properly connected to the sensor module. If it's not, connect the 4-pin current sensor connector into the sensor module. * Second, check for a faulty current sensor by verifying continuity between pin 3 & 4 (closest to the latch) of the current sensing connector. The resistance should be less than 1 ?. If it's greater, replace the current sensing module. * Third, a faulty sensor module could also be the cause. Try replacing the sensor module with a new one.
