Tech Note 1020 - Recording Diagnostic Logging
Scout 85.2 and above
This feature is designed to enable the controller to capture logs 20 seconds prior to MMU flash activation. These logs can then be transferred to CUBIC Support for a diagnosis of the fault.
To enable this feature, go to MM-8-8-5. Toggle “DiagnosticLog” to “ON.”
Once “DiagnosticLog” is enabled, the controller will maintain a current 20 second log triggered to write to memory upon MMU flash activation (Alarm 15).
NOTE: These logs will be overwritten every time the MMU flash is activated!
Alarm/Event #15 must be enabled via MM-1-6-1 and 1-6-4
With recorded log on controller, insert a USB and go to MM-8-8-8. Press enter and the logs will then be copied onto the USB.
Extract the file named “diag_log.dat” and send it to CUBIC Support for decoding.
- TS1/Caltrans Implementation:
To enable this feature when an MMU is not present you must redirect alarm #15 to Input Function #206-Cab Flash.
(Other Input functions could be used, just an Input that goes active when monitor latches a fault.)
NOTE: Input can be seen in MM-1-9-7-1.
To do this go to MM-1-6-7-2 and set Alarm #15 to be equal to Input #206.
NOTE: This must be done for diagnostic logs to be capture on a TS1 or Caltrans cabinet.
