1.12 Radar Console Failure Output
For installation where a continuous check of the radar console operability is
mandatory, a failure output is available.
The FAIL output is located on TB1 on the Alpha PCB and it is a NC contact that
can supply up to 200 mA of current (see Input/Output specification at this
Chapter’s introduction).
A special electronic circuit on the Antares PCB acts continuously as a watchdog
to detect any operational failure that can cause a processor malfunction.
Should a failure occur or the system is powered-off, the contact switches to
closed condition.
