1.3 Applicaon Informaon
1.3.1 Alarm Output
The Alarm output indicates if the
system is in an abnormal state such as a
Shutdown or PILOT FAILURE. The output
behaves as a switch. By default, it is
closed when there is no alarm condion
but this can be changed in the IO
sengs. External alarm circuitry should
be limited to 50mA (Image 1.3.1).
