Installing the Hoistway Limit Switches
In general (for cam-operated switches):
• Be sure that the cam operating the limit switches keeps the slowdown limit switches open
until the normal direction limit switch is broken.
• Be sure that both the normal and final limit switches are held open for the entire run-by
travel of the elevator.
• For faster elevators, the surface of the cam that operates the limit switches must be suffi-
ciently gradual so that the impact of the switch rollers striking the cam is relatively silent.
After Terminal Switches (UNT5/DNT5) are installed, verify Inspection Low Speed (iView/Pattern/
Inspection) is set to 25 fpm and is enabled. UNT and DNT 5 switches are always used in iControl installa-
tions.
