16.2 Infrared Transmitter

The infrared transmitter is installed in the crane of overhead machine. The LA70 IR module

generates and transmits the infrared signal. Each LA70 IR module has an identity code specific

to the system. This allows up to ten (10) LA70 IRs to operate in close proximity.

The LA70 IR module emits an Infrared signal in the shape of an elliptical cone. The dimensions

of the ellipse depend on the height of the LA70 and the orientation angle. The diagonals of the

ellipse, as they relate to height (with the LA70 pointing straight down) are shown in Table One.
