8.6.4.20.9: INNER LANDING ZONE
WARNING! Prevent persons from attempting to enter elevator during following tests by
guarding the entrance at the landing where the tests will be performed.
1) Show that the door zone is 150 mm (6 inches) long. Make actual measurement of door zone.
2) With elevator on normal operation, run elevator to a floor and allow doors to open.
• Note: With EBR: disconnect C01 connector to allow EBR to open brakes with power
on.
• With doors open, manually open the brake and allow elevator to drift UP 1 - 2 inches (25.4 -
50.8 mm).
• Successful test: elevator should relevel with doors open.
3) With elevator on normal operation, run elevator to a floor and allow doors to open.
• With doors open, manually open the brake and allow car to drift out of door zone, 3 - 4 inches.
• Successful test: elevator should close the doors and then relevel into floor.
4) With elevator on normal operation, run elevator to a floor and allow doors to open.
• Successful test: elevator is substantially at floor level BEFORE doors are fully open.
8.6.4.20.10: BRAKING SYSTEM, TRACTION, AND TRACTION LIMITS
Category 5 testing of emergency stopping device
Prior to performing 125% load high speed brake stop test, perform 125% load brake functional
check and verify each brake independently holds 125% load.
1) Move the elevator to an upper landing from where the car can accelerate down and reach
maximum speed.
2) Use switch 270 to put the car on machine room inspection while doors are still open.
3) Use switches 261 and 263 on LCECPU to inhibit landing calls and door opening, and override
110% load limit.
4) Load car with 125% of nominal load.
5) Check user interface menu 5-1. Menu should display about 125.
6) Put car on automatic. Car may relevel.
7) Register a call to the bottom floor.
8) Allow the elevator to accelerate to full speed. As soon as elevator reaches full speed pull XM1
connector on ADON2 board opening the safety circuit.
A successful test is:
• The main contactors open and the brake drops.
• The elevator slides to a stop on the brake and holds the load.
• WARNING! Do not stop the elevator by opening the mainline disconnect while the
elevator is running full speed as this may cause a flash over.
9) After the car stops, reconnect the XM1 connector on the ADON2 board.
10) Move the car to a suitable floor and enable the doors by sliding switch 263 to the right. Remove
the test weights.
