How Is The Sensitivity Of The Mahjong Machine?
Sep 18, 2017

Each brand of mahjong machine circuit and debugging methods are different, the most appropriate way is to directly reflect the problem to the manufacturers. General automatic mahjong machine debugging and maintenance guidelines are as follows:

First, the power switch is turned on, the switch indicator light does not shine, the machine does not have any reaction. 3, the power cord or power part of the connection line open; 4, the power fuse blown or poor contact; 5, the power switch is damaged; 2, the power plug is not plugged in, the power outlet is loose;

2, check the operation panel and the main control board is normal; 3, check the operation panel and the main control board is normal; 3, the operation panel and the main control board is normal; 3, check the operation panel and the main control board is normal; 3, the operation panel and the main control board is normal; , Check the lift assembly motor with the HL switch.

Third, the machine press the lift button operation panel does not move, no lifting action: the machine when the operation panel on the operation of the brand lights in the extinguished state, this time to make the operation panel to rise, you must also press the two lift button The

Fourth, the machine work process, while pressing the two lift button plate, the market is still rotating phenomenon: When the machine with the normal state of the card: at the same time press the two lift button, lift components rise, magnetic components, Delivery components, electromechanical components should stop working, fill the card is completed, just press a lift button, lift components that fall, the magnetic components, transmission components, mechanical and electrical components began to work. When the card components, transmission components, mechanical and electrical components are non-stop, indicating that the main core board has been damaged, should be invited to check the replacement of professionals.

5, the operation panel lift button bad; 3, HL installation is not in place or loose, poor quality; 4, check the lifting part of the implementation of components such as SCR and other components, such as thyristor, etc., (Note: should be checked by electrical professionals).

6, electromechanical components do not push the card action: 1, electromechanical components on the card body photoelectric sensor S1 bad or signal is blocked by foreign body; 2, determine the working state of the potentiometer variable value; 3, S1 working conditions do not meet the requirements of sensitivity too Low, should adjust the S1 potentiometer, so that meet the requirements; 4, the card is too dirty, so that the role of S1 shorter distance; 5, mechanical and electrical components motor plug loose or broken; 6, electromechanical components motor or phase loss capacitor damage , Variable value.

2, turn off the power, hand-cranked electromechanical components cam, check the lift at the lowest point and the card components on the rails are flat; 3, check the electromechanical components in the push card, the mechanical and electrical components of the card: The first card from the card after the mouth and the second card from the mouth down the level difference ≥ 1mm; 4, S1 photoelectric sensor bad or improper installation location.

8, the chain components of the motor has been non-stop: 1, when the first card is good, the chain assembly motor work will push the card to the next lift plate, after the end of the chain assembly motor to stop working. 2, when the four cards are good, the chain assembly motor has been rotating, should check the photoelectric sensor S4 is bad or blocked by foreign body; 2, when the four cards are good, the chain assembly motor has been rotating, 3, check the chain rod plastic reflective film surface with or without dirt after the dirt.

9, on the card components lift board licensing board is not normal: 1, when the normal card on the four components of the board is synchronized work, if found to have a board does not work, check the limit switch for damage; 2, if The board should be up and down action constantly, should check the limit switch pressure plate is on the limit switch has been in the state; 3, such as the board is not in place, adjust the limit switch plate position, so that in the licensing plate 4, such as the licensing plate sinks less than the lowest position, will cause the card, then just remove the card board, check the swing arm (feet) screws whether loose, off off , Swing arm (feet) slotted with or without deformation.

10, transport components into the card card or card does not enter the track: 1, remove the magnetic circle, check the size of the license, the level. When the card into the track should be slightly higher than the conveyor assembly timing belt; 2, check the transport components roller, timing belt, motor with or without bad.

11, the card after the end of the card number and the game method does not agree: 1, the digital switch is not in place or digital switch bad; 2, machine card to change the state of the digital switch, will produce the card after the end of the card number And the game method does not agree with the normal situation. This is because the process of changing the state of the digital switch, the change after the parameters will be in the next card to play a role. 3, light exposure or refraction S2, will produce more cards; 4, photoelectric sensor S2.3 is not installed in place or bad; 5, electromechanical components of the motor is not good; 4, the photoelectric sensor S2.3 is not installed in place or bad; , Work jitter, the speed is not normal or not in place; 6, due to operational errors caused by the program error, then just cut off the power, re-boot can be.

12, the motor is not working properly: 1, electromechanical components motor does not work: check the S1 signal is too weak to adjust the S1 on the potentiometer to its action; 2, the chain component motor stall: check the chain rod is stuck, S2 is 3, reverse the motor is not working properly: check the reverse button is good, the wire with or without cracking, off-line; for the control panel or motor; 4, the motor is not the same as the reverse, Turn: check the motor plug contact is good, the wire with or without cracking. To further determine the external 220V voltage single test motor operation. If the motor is running normally, the problem is mostly on the main control board. The main control board should be checked by the professionals.

13, shuffle dish does not turn: photoelectric sensor S6 before the reflective material block.

14, motor steering error: bad capacitor or motor error.

15, power off operation after more (missing) card: in the process of power card power failure, and then caused by power in the more (missing) card. The machine on the operation of the power cut off the memory program, under normal circumstances there will be no problem, but the operation process should try to avoid power failure phenomenon.

16, photoelectric sensor problem: 1, photoelectric point sensor photosensitive device, the intensity of light for the light is very sensitive. Should be noted in the assembly, commissioning process control of the light source, do not let the outside of the light source directly or reflected in the photoelectric sensor; 2, S1, S4, S5, S6 have a signal to determine the signal, no signal, When the signal is on (the white object passes through the photoelectric sensor), the indicator light is on. According to this feature, the photoelectric sensor can be easily discriminated, such as the actual work S1, S4, S5, S6 reflects the law and the above rules are different, then the photoelectric sensor has a problem, should be checked; 3, observe S1, S4 , S5, S6, such as in the absence of signal, the indicator light, although the machine is still working properly, but this work with the unstable working conditions, easy to make the machine failure. Should check the cause of the photoelectric sensor in the absence of the signal when the light and the reasons for the exclusion of 4, S1 in the installation of the light should be installed on the welding foot of a 1cm square insulator (with the iron ring cut down the flannel can 5, S1 on the potentiometer is used to adjust the light control sensitivity, clockwise rotation of high sensitivity, S1 see the distance; counterclockwise rotation sensitivity is low S1 see the distance near, under normal circumstances do not need to adjust. If you need to adjust, you should use the appropriate tools to slowly adjust the S1 potentiometer. Distance from the general control in the 1-1,2cm or so as well. S1 working conditions do not meet the requirements of the sensitivity is too low, should adjust the S1 potentiometer, so that meet the requirements; 6, photoelectric sensor in the installation, disassembly, careful not to allow the photoelectric sensor on the solder joint and metal parts of the machine, so as not to cause Short circuit damage photoelectric sensor, if not sure to turn off the power before the first to install or remove the photoelectric sensor
