ABSTRACT:
A microprocessor controlled garage door operator which eliminates lower and upper limit switches on the garage door in that the upper and lower limits are set in a program mode of the microprocessor with up and down control switches by the operator. The settings of the door are stored in the memory of the microprocessor. The microprocessor also sets the force limits by establishing them slightly above the actual force required to move the door up and down and this prevents the forces to be set greater than required which could result in a dangerous condition. An external security switch is also connected to the microprocessor of the garage door operator to allow the door to be opened by those knowing the code. In program mode, the user enters in the 4 digit code and the 4 numbers are stored.
