Machine Room Inspection (60) The car is on machine room inspection. Cannot be bypassed.
System Verifies:
- Mode of Operation = Inspection MR
1. If in error, verify position of machine room inspection switch.
MC-CPI (0) is Offline (320)
MC-CPI (1) is Offline (321)
MC-CPI (2) is Offline (322)
MC-CPI (3) is Offline (323)
The MC-CPI at this ID is offline. Fault-bypassed in Construction.
Correction:
1. Verify CPI connections and power.
2. Verify CPI ID switches correct and fully on or off.
3. Cycle power to the controller.
4. Contact MCE; possible defective MC-CPI board.
MDRE Failed to Turn Off (135) or
(412)
MDRE monitors the solid state drive DRE device. The device did not open
when expected. Cannot be bypassed.
Correction:
1. Check the associated wiring.
2. Verify the DRE system output.
3. Contact MCE; possible defective SCE-CPU board.
MDRE Failed to Turn On (136) or
(413)
MDRE monitors the solid state drive DRE device. The device did not close
when expected. Fault-bypassed in Construction/Inspection.
Correction:
1. Check the associated wiring.
2. Verify the DRE system output.
3. Contact MCE; possible defective SCE-CPU board.
MEB2 Redundancy Fault (423) Checks the emergency brake activation logic. MEB2 should be active
every other run.
Correction:
1. Check connector at DSE/EB2 on SCE-HVI board. If connection is cor-
rect, go to PLD DIAG > PLD INPUTS. View flag MEB2.
2. If MEB2 does not toggle every other run, contact MCE; possibly faulty
SCE-HVI board.
MEB3 Failed to Turn Off (283) MEB3 monitors the EB3 emergency brake device. EB3 did not go low
when expected. Cannot be bypassed.
Correction:
1. Verify the EB3 system output, PLD Diag > PLD Outputs > EB3P.
MEB3 Failed to Turn On (284) MEB3 monitors the solid state emergency brake device. The device did
not close when expected. Fault-bypassed in Construction/Inspection.
Correction:
1. Verify the EB3 system output, PLD Diag > PLD Outputs > EB3P vs. test
point EB3 on SCE-HVI board.
MEB3/4 Redundancy Fault (424) Traction Only. Checks emergency brake activation logic. MEB34 should be
active every other run.
Correction:
1. Go to SPB DIAG > SPB INPUTS. View flag MEB34 B. This flag should
toggle every other run. If not, contact MCE; possibly faulty SCE-HVI
board.
Motor Time Out (10) Failure of the car to reach a target floor in the allowed time.
Correction:
1. Modify motor limit timer to a value that allows car to run the entire
hatch without a fault.
2. Ensure that drive or starter is not shutting down during a run.
3. There may be a mechanical problem that prevents or slows the motion
of the car.
