If the infrared beam from the Excel transmitter is blocked or
inhibited in such a way that the intensity of the beam drops to a
level below the readable threshold set by the receiver, a warning
will be generated by the XNX transmitter. The Beam Block

When the beam is blocked longer than the value set in Time to
Beam Block, a fault is generated by the transmitter.
Set Time to Fault sets the minimum time the beam is blocked
before generating a fault.
