Load Weigher Thresholds
Analog load weighers provide a signal that corresponds to the load in the car. This value is used
to make dispatching decisions. Load thresholds are user-programmable.
This section is not applicable to discrete input load weighers. Please refer to “Load Weigher” on
page 3-24 or to manufacturer instructions for the installed load weigher.
• LIGHT LOAD WEIGHER (LLW)
• Used to define the load at which the number of car calls will be limited (anti-nuisance).
If the programmed number of car calls is exceeded, all car calls are canceled.
Example: LLW=20%. If the load in the car is less than 20%, the computer will only
allow a certain number of car calls to be registered as defined by the parameter LIGHT
LOAD WEIGHING? / LIGHT LOAD CAR CALL LIMIT in the EXTRA FEATURES
MENU OPTIONS. If the limit is set to a value of three, the computer will only allow
three calls to be registered if the load is less than 20%. If a fourth call is registered, all
car calls will be canceled.
• DISPATCH LOAD WEIGHER (DLW)
• Used to define the load at which the lobby landing door timer will be reduced so that
the doors may begin closing sooner, limiting the number of boarders. This threshold
should be set to a value (defined in many specifications as 60%) at which it is appropri-
ate to initiate the process of moving the car out of the lobby.
• HEAVY LOAD WEIGHER (HLW)
• Used to define the load value at which additional hall calls should be bypassed to avoid
overloading the elevator.
•OVERLOAD WEIGHER (OLW)
• Used to define the load at which it is considered unsafe to move the elevator. When
this threshold is exceeded, the car will remain at the floor with doors open and typi-
cally sound a buzzer or otherwise indicate that the car is overloaded.
