Abstract

PURPOSE:To prevent the signal output means circuit of a slave unit to be destroyed by outputting a short-circuit signal with the aid of a short-circuit detection means when short-circuiting occurs between a load circuit and the signal output means and stopping the output of the slave unit with the aid of a short-circuit control means. CONSTITUTION:When the short-circuiting occurs between the illumination load circuit 22 and the signal output means 11, the short-circuit signal is outputted by conducting a Zener diode 24, a light emitting diode 26 is lighted, a phototransistor 27 is turned on and the short-circuit signal is outputted to the short-circuit control part 8. The short-circuit control part 8 stops outputting by turning off the light emitting diode 13 of the short-circuit channel of a light adjustment control signal generation part 7 and stops the output of a light adjustment control signal from the signal output means 11 of the corresponding channel when the short-circuit signal is inputted. Thus the signal output means is not destroyed even when the short-circuiting occurs between the load circuit and the signal output means.
