6.5.3 Opening adjustment of electronic expansion valve
In case of the controller malfunction or faulty electronic expansion valve coil, electronic expansion valve
can be operated with fixed valve opening by using emergency cap.
If the electronic expansion valve is energized while the coil is removed from valve body, the coil driver
with which the valve needle is pushed protrude excessively. In this state, when the valve is restored from
emergency operation, the needle may be caught with the driver resulting the valve fully closed.
Therefore, be sure not to energize the coil before emergency operation.
[Disenergizing of coil]
When controller malfunction
Disconnect the red power supply connector (red : CN5) on the terminal board
when removing of controller short circuit connector (SCC1-1 or SCC1-2) to
disenergize the electronic expansion valve.(described in the section 6.5.2)
When only electronic expansion valve is conducted emergency operation.
Disconnect CN18 on the controller CPU board to disenergize the
electronic expansion valve.
Caution
