Recovery
Probe alarms P1, P2, P3 and P4 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, LA, HA2 and LA2 automatically stop as soon as the
temperature returns to normal values.
Alarms EA and CA (with i1 F=bAL) recover as soon as the digital input is
disabled. Alarm CA (with i1 F=PAL) recovers only by switching off and on the
instrument.
