Limit input circuits.
The interruption of current flow in these circuits is interpreted by
the controller as a limit condition.
4 AZ CCW Limit Return This pin is internally connected to the SUMMARY LIMIT RETURN
signal found on the Antenna I/O connector (J7 pins 17, 18)
16 AZ CCW Limit Input AZ CCW Limit input circuit.
The interruption of current flow in this circuit is interpreted by the
controller as a limit condition.
This pin is internally connected to the SUMMARY LIMIT input pin
found on the Antenna I/O connector (J7 pin 10)
