CONTROLLER
Document Type and Number:
Japanese Patent JPS58158711
Kind Code:
A
Abstract:
PURPOSE:To avoid the constitution of cams from being complicated even if steps are increased, while keeping the advantages of a program timer, by using the program timer set to an arbitrary position with a manual knob. CONSTITUTION:Changeover switches 3, 4 in the program timer 2 switch contacts (a), (b) sequentially with the rotation of a timer motor 13, and a moving contact (c) and the two contacts (a), (b) of the switches 3, 4 are connected to a microcomputer 1 respectively. An AC control circuit 9 switches on/off a switching element with an output signal from the computer 1 to control a load. Since the switches 3, 4 have three contacts including the off-position, 9 steps are formed in one course through the combination of the switchings. The steps are switched into 27 ways by providing three changeover switches and three cam plates.
