Limit Switches turn off
the motor when activated. They are usually used to prevent over-travel
of the slider or send an event signal. There are two types:
Adjustable (moveable) limits. Std on BiSlide; optional on XSlide
Standard BiSlide Assemblies have two adjustable
limit switches in a track on the side. They're specified by
either "21" or "31" at the end of the model
number.
An optional third limit switch can be added between the two
standard limits
and used as an adjustable home switch.
Limit switches can be omitted on the second side of a parallel
coupled BiSlide assembly. To do this, change your model number
from "21" to "20" or "31" to "30".
