RS-500 5K Walk-In Cooler Door Installation and Operation Manual
Section 3.6: Communication Between Smart Controller and Door
The head unit houses an encoder that sends electrical pulses to the Smart Controller when the door is moving and the controller
is in the normal operating mode. The controller tracks the position of the door in units known as "counts", which are based on the
number of pulses the encoder sends to the controller.
A count of 0 is assigned to the fully open position, whereas the highest count is assigned to the fully closed position. The
maximum number of counts the Smart Controller can read depends on the installation of the door. A single count is equivalent
to approximately 1/8" of movement. Several of the controller's parameters (including Actual Position, Open and Closed Limit
Positions, and Deceleration Range) are displayed in counts.
Section 3.5: Power Switch
The power rocker switch is located on the face of the Smart Controller. The switch controls power to both the Smart Controller
and the door.
