VORTEX FUNCTIONALITY
Speed Setting
The Vortex has a variable speed control which should be referenced against the speed and
rotation display. It is advisable to perform a speed check prior to the actual test to ensure
that the correct speed has been selected.
Speed & Rotation Display
The display will allow either actual speed or degrees of rotation to be displayed. The
required option is selected by pressing the SEL button on the left hand side of the display.
If the degree option is selected then the display will count up continuously with each
revolution e.g. 1.5revs = 540 degrees.
The RST button on the right of the display will reset the degrees of rotation at the point it is
depressed.

1. The enable button is released
2. The direction control is released
3. A pre-set alarm point is reached
4. The power is disconnected
Direction Control
