Position
The position function is used to manage control of reversible motors used in shade and black-out curtains,
ridge vents, side-wall vents and similar applications.
Position is controlled by tracking how long the motor is moving in the forward or reverse direction. The
“travel time” is the total amount of time it takes for the motor to move from the fully opened position to the
fully closed position, or vice-versa. If the system needs to open to 50% it will operate the motor in the for
-
ward (open) direction for half of the travel time.
General Parameters
The position control must be specified as a curtain (shading) or ventilation type. Absolute minimum and
maximum position limits can be placed on the setting with the range limit high and low slider positions. If a
static (fixed) position is desired, turn on the switch and set the position. The control setting will set the MX1
position to this static value when the setting is enabled.

If an operator manipulates the manual override

by the MX1i controller and the position relayed
back to the GCX control system. Upon returing
the knob to the Auto position, the system will
regain control of the MX1i controller.
