There is no switch in the trigger after the start of the power can be set to automatically set the time after the arrival of automatic power failure 100
For example, a machine only need to work for a few seconds to complete the action in the action is completed after the need for manual processing at this time need a switch to automatically power off to cut off the power to let the machine to stop working and can manually power Requirements are small equipment
Add the time to repeat the action after the device has completed the production action. This is the order in which the time of the repetition of the timing switch is not circulated. When the power is not needed, Standby but not completely off the power of a little confusing hope that we help a lot of problems I am troubled for a long time to find a lot of relay timers are not up to the request Thank you
Your description of the problem is very clear, but after the supplement is indeed a bit of confusion.
According to my understanding, is not click on the switch, the device runs automatically after the set time?
Or that is not the same as some of the corridor touch switch, click, light, delay a certain time, automatically extinguished?
If this is the case, from the circuit point of view, is a monostable circuit (commonly used 555 circuit to achieve).
Can be implemented using electronic circuits, can also be used to achieve the delay relay.
With a time delay to pull the time relay, a normally open button, a contactor to complete the entire circuit.
Wiring: 1. Firewire then open the button to the time relay closed point and then press the contactor coil and then to the zero line.
2. Contactor self-locking. Take the normally open ignition line through the contactor and connect to the button and the time relay.
3. Fire line through the contactor normally open point connected to the time relay power L-side, N then zero line.
4. Three-phase electric air open to the receiver and then to the motor
Wiring is complete.
Press the button (no lock button) contactor pull, self-locking to keep the contactor pull. At the same time the time relay power, began to delay. To set the time, time relay pull, normally closed point off. The contactor coil is de-energized. The motor stops. Until the start button is pressed again, the next job starts.
Simple can use the trip switch, installed in the work surface, when there is a work piece touched when the closure, after the cut off;
There is a proximity switch, inductive, electromagnetic, capacitive, photoelectric, and contactor combination, when the work piece is close to open the machine, after processing to complete the work surface automatically shut down the machine.
