METHOD OF DETECTING ABNORMALITY OF HEATING COIL

摘要

PURPOSE: A method is provided to be capable of detecting the abnormality of a heating coil by sensing a magnitude of a current flowing at the heating coil. CONSTITUTION: An operation start signal of an equipment comprising a heating coil is inputted(S1). After receiving table data, a current flowing at the heating coil is sensed(S2). The sensed current data is compared with the table data(S3). Whether a difference between the sense current data and the table data is within an allowed error is judged(S4). If the difference between the sense current data and the table data deviates from the allowed error an alarm signal is generated(S5), and if the difference between the sense current data and the table data is within the allowed error the sensed current data is stored in a memory(S6).
