17.1. Alarm 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 the 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 i1F = bAL) recover as soon
as the digital input is disabled. Alarm CA (with
i1F = PAL) recovers only by switching OFF and ON
the device.
