The following circuit controls an air-pressure engine (start-stop) and has over-load protections.
And the protection of the high temperature of the mechanical part of the compressor as well as the automatic operation of the compressor when full or lack of pressure in the air tanks, the motor works automatically when needed to load air. in addition to the operation manual.
Din1 is connected to the over load sensor, which senses current on the motor. Once the current exceeds the allowed limit, the circuit is switched off and will only function after the motor is repaired or the sensor is reset
Din2 connects with the heat sensor of the mechanical part which monitors the heat and stops the motor from working
Din3 connect to start-stop push button . When the push button is pressed, the motor works, provided that the air tanks are not filled and when pressed for the second time, it stops the motor manually
Din4 is connected to a pressure switch where the motor is controlled when full or air tanks are emptied and automatically operated
