First, The Circuit Failure
Overcoiling action (including hard overcoiling and soft overcoiling, and with the direction of the formation of blocking)
1, positive overcoiling action
Positive overcoil in the uplift are effective, positive overcoil action is displayed on the screen, when the distance reaches 0 continue to lift, soft overcoil action (as long as the conversion to the maintenance position under a distance can be automatically reset), hardware overcoil refers to when the overcoil switch action and the winch for the direction of the uplift operation (reset the travel switch)
2、Anti-overcoiling action is similar to positive overcoiling, only the opposite direction of operation
3、Brake pump failure, check the relay in the electronic control box
4, whether normal, and then check the 80 switch, check whether the motor is normal.
Second, After Hitting The Point Can Not Drive Normally
Drive points are correct, whether the gate is open (check the line), whether the main order is normal (check the line), whether the frequency converter is reported faults
Third, Drive The Process Of Sudden Stop
Loop failure, check the relevant faults, whether power failure, rectifier stops, frequency converter failure, etc., Shandong China Coal Industry and Mining Materials Group Co., Ltd. since its inception in line with the quality first, the principle of good faith with a number of coal mining enterprises, the Railway Group of the various branches of the establishment of a good relationship of cooperation.
