A system incorporating an actuator. The actuator may have a motor unit with motor controller connected to it. A processor may be connected to the motor controller. A coupling for a shaft connection may be attached to an output of the motor unit. The processor may incorporate a diagnostics program. The processor may be connected to a polarity-insensitive two-wire communications bus. Diagnostic results of the diagnostics program may be communicated from the processor over the communications bus to a system controller. If the diagnostic results communicated from the processor over the communications bus to the system controller indicate an insufficiency of the actuator, then an alarm identifying the insufficiency may be communicated over the communications bus to the system controller.
