Configuration and Troubleshooting
2-54 Manual # 42-02-2P26
Bottom Deviation (Edge) (220)
LS-EDGE-EL encountered terminal magnets that do not match learned
positions. Fault bypassed in Construction/Inspection.
System Verifies:
- Learned versus current-read magnet locations do not match within an
acceptable tolerance.
Correction:
1. Verify magnets for terminals have not been changed.
2. Relearn terminal magnets location by performing a hoistway learn.
BR Failed to Turn Off (256)
Traction Only. Brake contactor failed to open. Cannot be bypassed.
BR Failed to Turn On (257)
Traction Only. Brake contactor failed to close. Fault bypassed in Construc-
tion/Inspection.
Brake Pick Sw-Dropped (435)
Traction 0nly. Issued if brake pick switch is not in expected position after
an attempt is made to pick the brake. Performed only upon intent to
move. If BRAKE SW input is selected, when brake is picked, pick switch
must open the input terminal within three seconds. If BRAKE SW-C input
is selected, when brake is picked, pick switch must ground the input ter-
minal within three seconds. If not, car will stop at the next floor after
fault detection. If this fault occurs three times in succession, a latched
fault will be generated.
Correction:
1. Verify CONFIG 01 > CONFIGURE SPARE INPUT selected.
2. Verify switch mounting, function, and wiring.
Brake Pick Sw-Flaky (436)
Traction 0nly. Issued if brake pick switch leaves correct position after
brake has been picked. Performed only upon intent to move. If BRAKE
SW input is selected, after the brake is picked, the brake pick switch
must maintain a disconnected input terminal for at least 1 second. If
BRAKE SW-C input is selected, after the brake is picked, the brake pick
switch must maintain a connected input terminal for at least 1 second. If
not, the car will stop at the next floor after fault detection. If this fault
persists, an Excessive Faults event will be declared.
Correction:
1. Verify CONFIG 01 > CONFIGURE SPARE INPUT selected.
2. Verify switch mounting, function, and wiring.
Brake Pick Sw-Lifted (244)
Traction 0nly. Issued if brake pick switch is not in expected position
before an attempt is made to pick brake. Performed only upon intent to
move. If BRAKE SW input is selected, when the brake is dropped, the
pick switch must ground the input terminal within three seconds. If
BRAKE SW-C input is selected, when brake is picked, pick switch must
open the input terminal within three seconds. If not, car will be pre-
vented from starting. If this fault occurs three times in succession, a
latched fault will be generated.
Correction:
1. Verify CONFIG 01 > CONFIGURE SPARE INPUT selected.
2. Verify switch mounting, function, and wiring.
BRFLT is On (233)
Traction Only. The BRFLT input to the SCE-CPU board is high. Cannot be
bypassed.
BRP Failed to Turn Off (248)
Traction Only. NC auxiliary contact for BR contactor failed to drop out.
When idle, this input should be at 24VDC Fault-bypassed in Construction.
Correction:
1. Check BRP IDC terminal on SCE-CPU board for 24VDC. When BR con-
tactor is dropped, BRP should go low.
