Some issues with electric doors?
Thread Content
I’ve been working on adjusting an electric door recently and encountered a few issues I don’t understand; I’d like to ask everyone for help. 1. To open/close the electric door, the instrument sends out pulse signals lasting a few seconds; however, it takes over 10 seconds for the door to fully open or close. So how does the electric door achieve locking based on these pulse signals? 2. The electric door stopped before it opened fully, and a response was received. What’s going on? Does the 380V power supply get disconnected as soon as the open/close signal is received, causing the electric door to stop working?
The valve didn’t reach its full open position before stopping. I’m not sure at what position your valve stops – whether it’s near the fully open state. If that’s the case, there are two possible explanations: 1. The valve is in the correct position, but the indication on it is incorrect; in this case, the indicator inside the actuator isn’t properly fixed and is displaced, which causes the valve to stop before reaching its full open position. 2. The valve isn’t in the correct position, and the switch indicator inside the actuator is also incorrect. In this scenario, the mechanical contacts inside the actuator activate prematurely, resulting in the valve stopping.
Check whether there is a pause; the return of the signal indicates that the control module of the electric valve has detected the position signal, and it simultaneously sends a signal to the DCS as well as to its own control circuit. DCS generally aims to provide pulse signals. The pulse can maintain itself inside the electric actuator. Chips have registers!
1. To open/close the electric door, the instrument sends out pulse signals lasting a few seconds; however, it takes over 10 seconds for the door to fully open or close. So how does the electric door achieve locking based on these pulse signals? Answer: The DCS sends out pulse signals lasting a few seconds; the control circuit of the electric door uses relays to lock it in that position. The door remains open until a signal indicating that it has reached its fully open position is received. 2. The electric door stopped before it opened fully, and a response was received. What’s going on? Does the 380V power supply get disconnected as soon as the open/close signal is received, causing the electric door to stop working? Answer: It may be that the manufacturer of the electric door failed to adjust the limit switch to the fully open position during installation; another possibility is that the indicator for the fully open position of the electric door is incorrect, and it needs to be disassembled for inspection.
