Precautions for use:
1. Connect the plug correctly according to the wiring diagram
2. The Hall switch is NPN normally open type, and the detection distance of the Hall switch needs to be within 10mm. The diameter of the Hall switch is 12mm, and the wire length is less than 1m.
3. Strong electromagnetic interference should be avoided. It is best to use shielded wire or twisted pair for the measuring wire.
4. The switch or circuit for the counting signal and clearing signal input of the counter should be as close as possible to the terminal of the counter to make the signal line as short as possible.
5. Avoid connecting with other equivalent pipes or twisted wires such as strong electric wires or power wires to avoid unnecessary interference. If necessary, please use shielded wires. The shield is connected to the counting terminal "+".
6. It is not recommended to use mechanical switches or micro switches, because their life is relatively short, and it is easy to miscount after a long time; if using mechanical switches or micro switches, please use better quality to avoid miscounting, strong magnetic switch is recommended.
Common errors:
1. Eccentric circle Eccentric circle turntable, rotating up and down shaking speed is not accurate.
2. Hand-held Hall switch or hand-held motor is wrong operation, undetectable or inaccurate.
3. The magnet is not fixed and the detection is not accurate.
