ProLogic equations are used to activate and supervise the 79 test functions.
Normally each of these ProLogic equations would not be set to target, but for
this type of acceptance testing, it is convenient for seeing operations as they
happen.

ProLogic 1: This equation activates the reclose sequence. It sets the breaker
status (closes Out 5) via ProLogic 3.
