For the CS135, how are the warning or alarm conditions defined?

The CS135 has LED indicator lights that flash to indicate normal or fault statuses.
Where:

  • 1 flash every 10 seconds = OK, no fault
  • 2 flashes every 10 seconds = warning (possible degraded performance)
  • 3 flashes every 10 seconds = alarm (measurements not possible)

The output messages also contain information about Warnings and Alarms, known as the WA output. This is a single character with one of the following values:

  • 0 = No alarm or warning
  • W = Warning
  • A = Alarm

W or A are output in the message strings when necessary.

The description of the warning or alarm is obtained from the fault Flag code at the end of each message.
