Faults
CFLT Failed On Fault
COP CAN
Com Error
CPU APS DZOff Fault
Description
CFLT Input Failed ON.
The soft-starter fault
relay is check once a
day from the
controller by cycling
the STE, Starter
Enable, output off and
then on. When STE is
turned off the CFLT
input should go on.
After
the CFLT input turns
on, STE is turned back
on and CFTL is
expected to turn back
off. If CFLT stays on
and does not turn
back off, this fault is
logged.
COP Board Can
Communication Error.
The DZ-1/DZc input is
set from a position
count from the APS
Selector. This fault
occurs if the DZ-1/DZc
input is not on when
the DZ input from the
SAFETY PAL is on.
Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• Faulty soft-starter fault relay. Replace the fault relay.
• Faulty CFLT input. Replace the input board.
• Faulty STE output. Check that the STE output cycles off
and on by placing the car on inspection, change the time on
the Set Date and Time menu to 23:59 and then wait a
minute for the timer to roll over. Place the car on automatic
and watch the STE output. Once the flag is set from the
date rollover and the car does a redundancy test, the output
will be cycled. After STE turns off and then back on, the
soft-starter fault relay should cycle as well leaving the fault
relay energized and the CFLT input off. If the STE output
does not cycle, replace the output module.
• Faulty Can communication wire connection. Verify proper
twisted pair wires to the traveling cable CANH and CANL
terminals on the Main I/O board and on the COP board.
• Noise on the Can bus. Verify that the shield wire is
connected according to the job print.
• Verify the proper placement of the CAN Bus termination
resistors. It is best to have only one termination resistor at
each end of the serial link. Too many resistors will pull the
line down.
• The DZ/DZp output from the SAFETY PAL comes from the
combination of the following signals: NTS dz output, NTS
communicating with APS selector, Main CPU dz output and
Main CPU communicating with APS selector.• The Main CPU
dz output is DZO/DZcO and is set from the status of DZ-
1/DZc (the selector position count). DZO/DZcO and DZ-
1/DZc will always match. When DZO/DZcO is on, DZ from
the SAFETY PAL can be off due status of the DZ signal from
the NTS processor. However, when DZO/DZcO is off, DZ
from the SAFETY PAL must also be off. Contact the factory if
this fault occurs.
