What are the solutions to the faults of electromagnetic sucker controller?

First, the electromagnetic suction cup controller is equipped with an electric fuse

(1). Power on check whether the external wiring is correct 

(2). Check whether the insulation resistance of the disk to the ground (shell) is less than 1m Ω 

(3). Check whether the disk is short circuited 

(4). Check whether the input voltage meets the technical requirements 

(5). Check whether the disk used is consistent with the specification of the controller

 2. The electromagnetic sucker controller has the characteristics of electric explosion pressure sensitivity, while the capacitor has the characteristics of explosion

(1) . power on check whether the external wiring is correct 

(2). Check whether the input voltage meets the technical requirements 

(3). The electromagnetic chuck controller has no output the overcurrent indicator light is on 

(4) confirm that 1.1-1.4 is correct 

(5) check whether W2 is adjusted to its maximum value. If yes, adjust it to the middle position, then turn on the power, adjust W2 to the appropriate position as required 

(6). If necessary, connect the isolation transformer to the input of the controller

 3. Sometimes there is no output when the electromagnetic chuck controller outputs

 (1) When there is no output, observe whether the overcurrent lamp is on. Yes, please check 3.1-3.2 

(2) power on, check whether the controller wiring is reliable 

(3) check whether the hard disk connection is reliable 

(4) check whether the disk coil is in poor contact

 5. The electromagnetic chuck controller has output, but the grinding head of the main engine does rotate

 (1) Check whether the interlocking contact is correctly connected to the control circuit of the grinding head of the main engine 

 (2) adjust the W5 W6 potentiometers correctly according to section 4 / 3.6.1-3.6.2

 6. The safety tube varistor of the electromagnetic chuck controller are normal, but there is no output during charging demagnetizing

 (1) Shut down, check whether the external wiring is correct 

 (2) check whether the external potentiometer is adjusted to the minimum position, if so, please adjust it to the middle position, then turn on the power, then adjust the external potentiometer to the appropriate position as required 

 (3) check whether the W2 potentiometer is adjusted to the minimum position. If yes, adjust W2 to the middle position, remove the external potentiometer, turn on the power, then adjust W2 to the appropriate position as required (1 #, 2 # output should exceed dc110v) 

 (4) in the above three error free states, disconnect the output load external regulator to ensure the state transition The switch works normally, the input terminal is powered on, after a delay of about 1.5s, please test according to the following requirements. If the following conditions are met, the charging demagnetizing controller can be judged to be normal. 

 (5) use a multimeter (DC20V file) to measure the voltage between 5 10 is about 15V. 

 (6) use a multimeter (DC500v range) to place the switch in the "magnetization" position, measure the output voltage (terminal 1 is negative) between 1 # 2 # should be about 1.4 times of the input voltage; set the switch to the "stop magnetization" file, the output voltage should be zero. Set the switch to "degaussing" gear, the output voltage shall oscillate forward backward (with the same amplitude as the magnetizing voltage), then return to zero after 3-18s.
