6.2 Device Fault in Fault Log
This section describes the specific device faults from devices on the Machine Room CAN BUS (MRCAN),
Car Top CAN BUS (CTCAN) and Group CAN BUS (GRCAN) serial ports.
When a device sends a fault to the Main CPU, the Main CPU logs the fault according to the CAN BUS
port that the device is connected. For example, if a device on the Machine Room Can bus (MRCAN) has
a fault, the fault is logged as a MRCAN Device Fault. When the fault is received from a device on a Hall
Call Driver Board or a Car Call Driver Board, the fault is logged as an HCB Device Fault or a CCB Device
Fault, respectively. The actual fault that occurred on the device is stored as part of the fault data and can
be viewed when selecting the details of the fault from the Galileo or the fault log that is stored on the SD
Card.
When viewing the faults on the LCD Display Interface, instead of showing an MRCAN Device Fault, a
GRCAN Device Fault, a CTCAN Device Fault, an HCB Device Fault or a CCB Device fault, an
abbreviation of the device name and bus is displayed followed by the actual device fault. The format for
the data displayed on the LCD Interface is as follows:
DevP## FAULT
Where Dev is the device name such as SEB (serial expansion board) and P## is the port and address
number if applicable. The CAN BUS ports are listed as G=GRCAN, C=CTCAN and M=MRCAN. The ##
is the device number having a value between 1 and 99. FAULT is the specific device fault. A list of the
device names is show below:
NTS – NTS Processor
DOOR – Front Door Operator on CTCAN port
RDOR – Rear Door Operator on CTCAN port
LW M – Load Weighing Device on MRCAN port
LW C – Load Weighing Device on CTCAN port
VS M – Voltage Sensing Device on MRCAN port
VS C – Voltage Sensing Device on CTCAN port
VS G – Voltage Sensing Device on GRCAN port
PI M – PI Device on MRCAN port
PI C – PI Device on MRCAN port
SEBM – Serial Expansion Board on MRCAN port
SEBC – Serial Expansion Board on CTCAN port
SEBG – Serial Expansion Board on GRCAN port
COP – Car Operating Board on CTCAN port
HCD – Hall Board on HC Driver Board on GRCAN port
HCB – Hall Call Board on GRCAN port
An example of an APS Com Fault for the NTS processor device would be displayed as “NTS APS Com
Fault”. In addition, a stuck Up button on a hall call driver board device would be displayed as “HCD 14
Stck Up Buttn”. To troubleshoot the device fault, look up the FAULT portion of the message and follow
the described suggestion.
Similarly, when a device is reset on one of the CAN BUS ports, the device name, port and address
number is displayed the same as described above but with the FAULT section being shown as “Device
Reset”. An example of a Serial Expansion Board #05 device reset on the group can bus (GRCAN) would
be “SEBG05 Device Reset”.
The device faults are listed in the following tables:
