Zusammenfassung: | PURPOSE:To ensure the safe mode setting, by providing a working mode error display circuit which displays an error of the working set mode with the output of a working mode discriminating circuit and displaying the error without actuation of a timer when a user set a wrong mode. CONSTITUTION:A timer circuit 1 has a timer limiting action by the set contents of a working mode setting part 2 and a limiting time setting part 3. While, the circuit 1 has no working when a signal showing a wrong set working mode is received from a working mode discriminating circuit 4. Then a working set mode error display circuit 5 displays an error of setting when a signal from the circuit 4 is received. |
