Verifying One Floor Run Operation
The first step in verifying one-floor run operation is to verify proper correction, run, and stop.
Verifying Correction, Run, and Stop
1. Arrange the elevator for empty car conditions.
2. On the Configuration > Pattern > Common tab, set Pattern scaling to 50%. This directs
the car to run at 50% of the commanded speed.
3. Move the car on Inspection to a location between floors, more than one foot away from a
landing so that no leveling sensors are engaged.
4. Place the car in Test mode (iBox Test switch ON). Set the iBox Fault Bypass switch to
ON.
5. Set the terminal limit switches to their default settings (View > Setup > Terminal
Switches) to allow the car to run.
6. Take the car out of Inspection operation (iBox Inspection switch in the NORM position).
The car will perform a Terminal Synchronization, using the learned position of the sen-
sor to update the current position reported by the position encoder.
If a Limits Switches Checksum Fault is generated when the car is removed from Inspection operation, it
will be necessary to set the terminal switches to default values before proceeding (View > Setup > Termi-
nal Switches tab). Perform the procedure shown in the Terminal Learn message window titled “To
default terminal switches, please do the following:”.
7. If the car corrects and stops properly, proceed to Initiating a One Floor Run later in this
section.
If the Car Does Not Stop and Correct Properly
•Check the iBox status display. Verify:
• ULM, DLM, and DZ signals are working properly
• Safety OK = ON - safety string is made up.
• Doors Locked = ON - all doors are locked.
• Inspection = OFF - not on Inspection operation.
• Fault = OFF - no faults are active.
