Confirm that the main controller and the Liugong excavator actuator controller have no fault, and the 888 # wire has a voltage input, and the actuator still does not move, and the confirmation can be checked as follows.
Use a multimeter-powered 2009 gear measurement check the actuator, check the actuator's plug, when the actuator pusher is not in the extreme position (received head or extended to the head), at this time, the following should be measured:
If the actuator does not meet the above measurement results, it is necessary to check that there is no loose in the plug at the plug. For the pin, when the opening or time is good, it is necessary to use the hand-to-catch wire whether there is an external force (wire " Broken, the insulation layer is intact), if the above pin is loose and the wire is not subject to the external force, it can be considered an actuator failure.
Note: Note Sequence No. 3 In content, if the total resistance is 20K actuator, it may not be equal, and it may be noted that the color of the wire color may change in the plug should be taken.
