ALARM RECOVERY
Probe alarms “P1”, “P2” and “P3” 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 “LA2” automatically stop as soon as the temperature returns to normal
values.
Alarms “EA” and “CA” (with i1F=bAL) recover as soon as the digital input is disabled.
Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
