13, Troubleshooting
1. Fault phenomenon: the cylinder cannot operate.
Solution: (1) Manually pull the cylinder to see if it can move.
(2) Check the air source to ensure that the pressure of compressed air entering the cylinder is large enough.
(3) For solenoid valve inspection, first measure whether the solenoid valve power supply voltage is 24VDC and whether the plug is firmly inserted. The solenoid valve can be checked manually to see if there is an energized switching sound.
(4) On the monitoring screen, manually control the cylinder, and the voltage of the corresponding solenoid valve should be 24 VDC, which can be measured with a multimeter. Generally, there is no voltage or the valve itself is damaged.
2 The sensor on the monitoring screen has no force value or obvious force value error.
Solution: (1) Recalibrate and pay attention to the installation direction.
(2) Check the power supply. The supply voltage of the sensor is 24VDC
(4) By changing the positive and negative signs of the sensor's correction coefficient, you can simulate the action of the cylinder by hand when the test is being carried out to see whether the direction of the displayed force value is correct.
4 Magnetic reed switch does not work.
Solution: (1) Check the power supply. The supply voltage of the sensor is 24VDC,
(3) For output inspection, remove the output wire. After the magnetic spring switch senses the magnetic ring in the middle of the cylinder, the light on the switch will be on, and the output voltage is 24VDC.
