CT Ins Stuck Input (90)
Cartop inspection Enable, Up, and Down inputs are monitored in all
modes. This fault is asserted if any of the three is high when the car is on
Automatic mode or is detected as stuck during inspection mode. This
fault does not affect car behavior on inspection mode. On automatic
modes, the car is allowed to answer its first call. The CT Ins Stuck Input
Flt is then asserted if the car is already at a floor or has reached a floor.
(See description below.) Fault-bypassed in Construction.
Correction:
1. Check all Car Top Inspection related inputs, switches, and related wir-
ing (SCE-CPU CTEN, ICTU, and ICTD).
CT Ins Stuck Input Flt (91)
A stuck Cartop Inspection input has been asserted (see above) and the
car is already at a floor or has reached a floor. The doors open to release
passengers and the car removes itself from service. Fault bypassed in
Construction mode.
Correction:
1. Verify switches and wiring on SCE-CPU inputs CTEN, ICTU, and ICTD.
Cycle Test - “nnn”
nnn = ESC (293), INA (296), INCP (297), INCT (295), M2L (300),
MRIN (298), MASF HIGH (299), MASF LOW (309), PLD COMM (308),
PLD ESC (301), PLD INA (304), PLD INCP (305), PLD INCT (303),
PLD MRIN (306), PLD SAFC (302), SAFC (294), SPB COMM (307)
Before departing a floor, code requires safety related inputs be tested to
ensure they are in the proper state. If an error is found, a Cycle Test fault
specific to the problem input will be displayed. Fault-bypassed in Con-
struction/Inspection.Correction:
1. Verify installation, condition, and connections for the specified equip-
ment.
Cycle Test M2L (300)
Reset fault. Go to PLD Diag > PLD Inputs; view flag M2L. Place a call for
a landing. M2L must turn off when doors open and stay off until door
locks are reestablished. If doors are operating properly, SCE-HVI board
may be faulty.
Cycle Test MSAF High (299)
Reset fault. Go to SPB DIAG > SPB Inputs: View flag MSAF B. Place a call
for a landing. MSAF B must turn off when doors open and stay off until
door locks are reestablished. If doors are operating properly, SCE-HVI
board may be faulty.
DFE/EB1 Stuck Off (144)
Down Fast Enable or emergency brake outputs remain off when com-
manded to be active. No bypass in any mode.
Correction:
1. Verify emergency brake output is correctly connected.
2. Verify function of emergency brake unit.
DFE/EB1 Stuck On (143)
DFE/EB1 reset issued but outputs remain on. No bypass in any mode.
Correction:
1. Verify emergency brake output is correctly connected.
2. Verify function of emergency brake unit.
DFLT is On (140) or (417)
Drive has faulted. Not generated in construction operation. Fault
bypassed in Construction/Inspection.
1. Verify status of DFLT input.
2. Check drive for fault indication and troubleshoot.
