The advantage of the presence of the X axis LED bar indicator is that the corresponding LEDs light up right in the center of the required compartment. It is quick and easy to understand which compartment it is and to speed up the movement.
The number of LEDs lit each time is customizable, obviously it depends on the length of the tray and therefore of the bar, calculating a resolution of 10 mm.
The length of the mounted bar and tray depend on the Modula model, thus covering the entire width of the tray, without any interruption except for the two ends of the bar where 25 mm free are needed.
