Abstract
A microcomputer implemented control device having maintenance provisions. Indicators (such as light emitting diodes) are provided on the inputs and the outputs of the microcomputer along with switches to override the normal input or output. As a result, both the inputs and the outputs can be "forced" to a given state to be able to differentiate between a failure in ancillary equipment and a failure in the microcomputer itself.
