7 — DIAGNOSTIC AND TROUBLESHOOTING
e controller has two status LEDs, one red and one yellow LED. e present status of the controller
can be ascertainable within seconds by observing the status LEDs. Each fault will ash a specic code.
THE DIAGNOSTICS PROCESS
Diagnostics information can be obtained in either of three ways: (1) by observing the fault codes
ashed by the controller’s status indicator, (2) by reading the indicated fault (
) in the Curtis Soware
Suite
TM
Programmer app, or (3) the CAN Emergency Messages.
Table 22 species the condition and associated ash pattern for the 1351 System Controller LEDs.
Table 22 LED ash patterns
Condition Red Yellow Pattern
OK Off
Flashing at a 1.5 sec
cycle.
ON = 500 ms
Off = 1000 ms
Programming ON ON
Dead ON OFF
Error
Flash Code digit 1
250 ms ON
250 ms OFF
Flash Code digit 2
250 ms ON
250 ms OFF
Each code is followed by a
2-second pulse, and the next
code is started.
Invalid Software Fast Flash OFF
The Normal/OK state is shown by only on the yellow LED flashing a 1 at a 1.5 sec cycle rate.
Additionally, the On-time is lengthen to a full 500 ms, thus further dierentiates it from any Error
ash code.
Programming is shown using two formats:
• Initiate Programming and End of Programming = Both LEDs ON 100%,
• While data is incoming = Red LED ON and Yellow LED fast ashing
Non-operation (dead) state is shown by the RED Led 100% on and the Yellow LED o.
Error Codes (faults) are shown on the Status LEDs using a sequence of ashes and pauses. e
technique used is a departure from the previous Curtis motor controller standard (e.g., E/SE
controllers). e 1351 uses a format where the Red LED ashes the upper Tens digit number and
the Yellow LED ashes the lower Ones digit number. e ash cycle is 500 ms with a 250 ms On time.
If there are multiple codes, they are ashed in succession with a 2-second pause between each. ere
is an additional 2 seconds added to the last ash code in the list (4-second total pause) to denote the
last Error code has be ashed.
Examples: (Each block = 500 ms)
Normal/Ok/No errors
• On/O cycle within each block = 100% (thus, the On time is 500 ms)
