Door Open and Door Close Logic
SmarTraq is designed to allow power to be applied indefinitely to hold doors open or closed.
With some controller designs, i.e. Otis, a single relay or single family of relays is energized to
open doors and then that same relay or relays are de-energized to close doors.
Self-Holding
Hold open torque parameter “Co” is used to hold doors open and hold close torque parameter
“Cc” is used to hold doors closed. This feature is especially useful if doors tend to drift partially
closed when open command is removed or when fully open, or to drift partially open when fully
closed or when close command is removed. Using the Co and Cc parameters, SmarTraq is self-
holding in full open or full close positions. (If doors drift closed when controller power is
removed, then some sort of door hold open device may be required.)
Door Close Limit and Door Open Limit
DCL and DOL are generated electronically when doors reach full close or full open position, up
against the bumpers, and current increases. After an unobstructed “learn operation”, SmarTraq
knows the difference between an obstruction and full open or full close position. DCL and DOL
can only be generated within approximately the last 1/2-inch (13mm) of travel.
DOL and DCL have loss of power memory. When power is restored after a power loss, DCL will
be re-established if doors were fully closed or DOL will be re-established if doors were fully
open prior to power interruption.
