All eC.A.T4 and gC.A.T4 models are equipped with sensors to detect incorrect usage and warn the operator with an alert that is also stored in the data log. 

This warning is known as a Swing Warning.

Warns that a C.A.T4 is being used too far from the vertical or moved too quickly for a reliable cable or pipe location.

Swing Warning

The is represented in the CSV data exported from the C.A.T4 under column 'S' as either a Yes/No or disabled. 

A Yes indicates that the C.A.T reported a Swing warning.

A further representation of this can be found in columns 'X' and 'Y' Blade and Paddle angles respectively and is represented as an integer scale figure.

In short, When the C.A.T4 in the vertical position, the blade angle is forward and back and the paddle angle is left to right. Likewise, if the C.A.T is in the horizontal position the blade angle is left and right and the paddle angle is forward and back. This is associated with the Swing warning that is registered on a logging C.A.T such as an eC.A.T4 and a gC.A.T4.
