Daikin LXE10E136 - Emergency Operation of Electronic Expansion Valve

6-23
6.5.3 Emergency operation of electronic expansion valve
If the controller does not work or the electronic expansion valve coil has failed, the emergency magnet
can be used to fully open the electronic expansion valve.
①Disconnect the CN11 connector from the power supply I/O board of the controller to forcibly turn OFF
the power supply to the electronic expansion valve.
②Prepare the emergency magnet.
③Remove the electronic expansion valve coil.
④Bring the emergency magnet into contact with the coil mount section of the electronic expansion
valve body with indication "UP SIDE" located upward. (The emergency magnet is magnetically
attracted to the coil mount section by the driving magnet located inside.)
⑤Turn the emergency magnet in the OPEN direction (clockwise) in the same place.
→Ensure that the valve is fully open. (There is a small click sound.)
⑥Turn 90˚ to 180˚ counterclockwise the emergency magnet in the same place.
To shorten the operation time, it is recommended that the opening be adjusted. However, slightly close
the opening if there is a frost around the compressor due to the operation in wet conditions or the
degree of superheat is small.
