12.1 ALARM RECOVERY
Probe alarms P1” and “P2” start some seconds after the fault in the related probe; they automatically
stop some seconds after the probe restarts normal operation. Check connections before replacing
the probe. Temperature alarms “HA” and “LA” automatically stop as soon as the temperature returns
to normal values.
Alarms “EA” and “CA” (with iF=bA) recover as soon as the digital input is disabled.
