Abn" – ALARM CONFIGURATION:
The parameter can assume a value between 0 and 15.
The number to be set, which will correspond to the desired functioning, is obtained adding the values reported in the
following descriptions :
ALARM BEHAVIOUR AT THE SWITCH ON: It’s possible to have 2 different behaviours of the alarm output, depending on the
value added to par. “Abn”.
+0 = NORMAL BEHAVIOUR: The alarm is always activated when there are alarm conditions.
+1 = ALARM NOT ACTIVATED AT THE SWITCH ON: Whether, at the switch on, the instrument is in alarm conditions, the
alarm is not activated. It will be activated only when the process value is out and back again in alarm conditions.
ALARM DELAY: It’s possible to have 2 different behaviours of the alarm output, depending on the value added to par. “Abn”.
+0 = ALARM NOT DELAYED: The alarm is immediately activated when the alarm condition has come to pass.
+2 = ALARM DELAYED: When the alarm condition has come to pass, it starts the counting of the delay, as programmed on
par. “ALnd” (expressed in sec.) and only after the elapsing of that time the alarm will be activated.
ALARM LATCH: : It’s possible to have 2 different behaviours of the alarm output, depending on the value added to par. “Abn”.
+ 0 = ALARM NOT LATCHED: The alarm remains active in the alarm conditions only.
+ 4 = ALARM LATCHED: The alarm is active in the alarm conditions and remains active also if these conditions are not
existing anymore, until when key “U”, properly programmed (“USrb”=Aac) has been pushed.
ALARM AKNOWLEDGEMENT: : It’s possible to have 2 different behaviours of the alarm output, depending on the value added
to par. “Abn”.
+ 0 = ALARM NOT AKNOWLEDGED: The alarm remains always active in the alarm conditions.
+ 8 = ALARM AKNOWLEDGED: The alarm is active in alarm conditions and can be deactivated through key “U” if properly
programmed (“USrb”=ASi), also if the alarm conditions are still existing.
"ALni" – ALARM ACTIVATION IN CASE OF MEASURING ERROR:
it permits to establish in which way the alarm has to behave
in case of measuring error (yES=alarm active; no=alarm deactivated)
