The following provides a brief description of the GSP control (refer to the sketch below):

The Cycle Push Button

When this momentary device is pressed for one second while the Run/Stop switch is in the
Stop position, the control will toggle between Manual Mode (Hnd) and Automatic Mode
(Aut). When in Automatic Mode the Auto Cycle Mode LED will be illuminated.

The Cycle Push Button is also used to increment/decrement the values/settings of the program
variables (refer to the section “Programming The Automatic Cycle Parameters/Variables” later in this
manual for further details of this function).

The Run/Stop Switch

This is used to start and stop rotation of the positioner in Manual Mode and is used to start
and stop an automatic cycle in Automatic Mode.

The Hold (Stop) position is also used to reset most error codes once they have been rectified.

The Forward/Neutral/Reverse Switch

This is used to select the direction of rotation in Manual Mode and must be in the Neutral
position to allow an automatic cycle.

The Forward position is used to select increment, while the reverse position is used to select
decrement as the method of changing the values/settings of the program variables (refer to the
section “Programming The Automatic Cycle Parameters/Variables” later in this manual for further
details of this function).
