12.2 SILENCING BUZZER / ALARM RELAY OUTPUT
Once the alarm signal is detected the buzzer, if present, can be disabled by pressing any key.
XT111C/XT111D: the alarm relay status depends on the tbA parameter: with tbA=yES the relay is
disabled by pressing any key, with tbA=no the alarm relay remains enabled as long as the alarm lasts.
The display signal remains as long as the alarm condition remains.
12.3 ALARM RECOVERY
Probe alarms “PFo”, “PFc” start few seconds after the fault in the probe; they automatically stop few
seconds after the probe restarts normal operation. Check connections before replacing the probe.
Max. and min. alarms “HA” and “LA” automatically stop as soon as the variable returns to normal values.
Alarms “bAL” and “EAL” recover as soon as the digital input is disabled.
