Claims

[Scope of utility model registration request]

In a controller that uses a microprocessor and has a mode selection switch that switches between manual adjustment mode and automatic adjustment mode, it monitors the operation of the microprocessor, detects malfunctions, outputs a fail signal, and also sends a restart signal to the microprocessor. A monitoring circuit for sending out a reset pulse is provided, and the microprocessor is capable of restarting only when a confirmation operation is performed to set the mode selection switch to the manual adjustment mode side when the monitoring circuit generates a fail signal. Controller.
