EP Run (24)
The car has been selected to run under emergency power. Cannot be
bypassed.
System Verifies:
- EP Data Status = EP Run
Correction:
1. If in error, check that the EP Run has not been erroneously assigned to
an input or, if a valid input has been assigned, verify the electrical
state of that input and that it is wired correctly.
2. Verify EP Auto (System IO > Programmed Inputs).
EP Shutdown (19)
Normal power has been lost and the car is stopped. The car will remain
stopped until backup power becomes active or commercial power is
restored.
System Verifies:
- EP Data Status = EP Shutdown
Correction:
1. If in error, check status of System IO > Programmed Inputs, EPI.
2. Verify EPI not programmed if not used.
3. If used, verify EPI wiring per job prints.
EQ Emergency Stop (94)
Earthquake inputs EQ SS or EQ CWT have been activated and the car has
performed an emergency stop. Further operation will be per the selected
earthquake code. Fault-bypassed in Construction.
System Verifies:
- Earthquake Data = EQ Stop
Correction:
1. Verify System IO > Programmed Inputs, EQ SS or EQ CWT.
ESC Input Low (162)
The in-car emergency stop switch bypass input is low. If moving, the car
will perform an emergency stop. The doors will not operate.
System Verifies:
- ESC input is low
Correction:
1. If in error, verify input and input device electrically and mechanically.
2. Verify status System IO > System Inputs ESC.
Ethernet Error (251)
Monitoring processor cannot communicate with the Ethernet chip. Cannot
be bypassed.
Correction:
1. Verify Ethernet connection.
2. Verify Ethernet settings (Config 03 > Network Settings).
3. Reset processor SPC (RSTC button on SCE-CPU board).
Event Log Cleared (228)
Message will appear momentarily when event log is cleared through the
touch screen. System Diag > Event Log > Clear.
Event Log Write Fail (167)
Occurs if the SPC processor tries to write an event to the SD card but
cannot. Car runs normally.
Correction:
1. Verify SD card is installed; eject and reseat.
2. Clear the event log.
