タ制御機器。 A microcomputer-controlled device that operates a load under the control of a microcomputer in response to an on operation of a power switch is provided with a normally closed contact that opens when the power switch is turned on, and the microcomputer controls the normally closed contact. Detection means for detecting open/closed status, and when powering on,
When the open state of the normally closed contact is detected by the detection means, an error is displayed, and when the closed state of the normally closed contact is detected, the load is controlled in response to the subsequent opening operation of the normally closed contact. A microcomputer control device comprising: a control means for starting the process.
