Description

Application

When switching the key:

R1 = 2.2mOhm, R2 = 1mOhm - Time ON - 22minutes, OFF - 11 minutes;

R3 = 1mOhm, R4 = 560kΩh - Time ON - 9 minutes, OFF - 3 minutes and 30 seconds;

R5 = 33 kOhm, R6 = 33 kOhm - Time ON - 20 seconds, OFF - 10 seconds.

when the key is in the middle position, only R1 and R2 are signed when in position 2 to R1 is added in parallel R3a to R2 is added in parallel R4 and in position 3 to R1 is added in parallel R5 and to R2 is added In parallel R6.

when a voltage is applied to the integrated circuit, the capacitor C1 begins to charge, resulting in a voltage close to the power supply (12V / DC) at the terminal 3 of the integrated circuit and releases the transistor T which triggers the relay P.

аfter the capacitor C1 is loaded into the integrated circuit, the transistor is disconnected, which connects between the 1 and 7 terminals of the integrated circuit, which causes the capacitor to start to discharge.

after the dilution begins again, this cycle is repeated. The charging and discharging time is determined by two resistors (two resistors) that are switched by a switch.
