よい。 Next, when the servo motor is locked, the ON signal from the servo amplifier 26 to the motor lock safety circuit 28 continues for a certain period of time, so the lock safety timer in the motor lock safety circuit 28 goes up and applies voltage to the resistors 29 and 30. do. As a result, transistor 31 turns on, and resistors 20 and 21
As the current to the transistors 24 and 25 decreases,
OFF, and the power supply to the servo amplifier 26 and motor drive circuit 27 is turned OFF. As a result, no voltage is applied to the servo motor 33,
The mixing valve 2 then stops. During this servo lock, it is impossible to adjust the mixing valve 2, but since the combustion control circuit 17 and the heating control circuit 18 operate normally, it is possible to use the system for heating or for supplying hot water to other taps. The lock can be released by turning the operation switch 10 OFF and ON.
