8.6.4.19.12: TRACTION LOSS DETECTION MEANS
1) Capture elevator and disable landing calls and door movement by sliding LCECPU switches 263
and 261 to left.
Note: Ensure no passengers are in car.
2) Drive elevator to a floor where floor-to-floor distance to next floor above is at least 8 feet (2.5 m).
Alternate method: For elevators equipped with V3F25 drives or if there are no floor-to-floor
distances greater than 8 feet (2.5 m), switch to machine room inspection and power down and
disconnect 61:U and 61:N signals at LCECPU XC11/5 and 6.
Note: Disconnecting 61:U and N signals allows elevator to run past next floor without resetting
TLD supervision.
3) Switch to machine room inspection.
4) Verify parameter A.17 Compliance Year, 7-43 =7 or higher.
5) Set parameter TLD supervision time, 5-15=10. Cycle controller power.
Note: Can only be set while on machine room inspection.
6) Set inspection speed, 6-20 to 0.2 or lower. Save using 6-99=1. (This is not possible with V3F25
drives.)
7) Unplug ADON2 connector XCT.
8) Run elevator on machine room inspection in up direction. A successful test is after about 10
seconds:
a) Elevator makes an immediate stop and drops brakes.
b) Fault 0002 appears on UI.
c) Elevator will not run on machine room inspection or normal operation.
9) Cycle controller power and verify:
a) Fault 0002 is present.
b) Elevator will not run on machine room inspection or on normal operation.
10) Reset TLD by turning TLD reset key switch to RESET for one second and then to NORMAL.
