Directional Limit Distance, 68 This is the distance in inches at which the Directional Limit “switches” are placed beyond the terminal floor level positions. The value is entered in inches and is computed from the position of terminal floor levels. For example, a value of 2.0 would place the switches 2” past the level at floor position for each terminal. If the car fails to stop level at the terminal, this “switch” will prevent the car from traveling further past the terminal landing. These “switches” must be positioned between the terminal floor level and the mechanical Final Limit Switches. If a car reaches the Final Limit Switch, the hoistway safety string will open and it will be necessary to jumper out the safeties to move the car off the limit.
