2.6.1 Configuration menu
To configure alarm 1, access the ‘Alarm
1’ (‘ALr1’) menu and config
-
ure the following parameters : To configure alarms 2, 3, etc, access
the corresponding menu entries.
• select ‘
Active
’ (‘Act’) to ‘on
’
• at ‘
Alarm type’ (‘TypE’) select the maximum alarm (‘MAX’) or
minimum alarm (‘
MIn
’). The maximum alarm (or type alarm) ac
-
tivates when display value is higher (or lower) than the setpoint
value.
• at ‘
Setpoint’ (‘SEt’) enter the alarm activation value.
• configure the hysteresis value at ‘Hysteresis’ (‘hySt’). The hyster
-
esis applies to the deactivation process of the alarm. The alarm de
-
activates when the reading has passed the setpoint value plus the
hysteresis value.
• at ‘
Delay 0’ (‘dEL.0’) assign the delay to be applied before alarm
activation. The activation delay starts counting when the setpoint
value is passed. Configurable from 0.0 to 99.9 seconds.
• at ‘
Delay 1’ (‘dEL.1’) assign the delay to be applied before alarm
deactivation. The deactivation delay starts counting when the set
-
point value plus the hysteresis value, is passed. Configurable from
0.0 to 99.9 seconds.
• to activate the second setpoint, activate ‘Setpoint 2’ (‘SEt2’) to
‘
on’ and then configure the desired setpoint value. Second setpoint
allows for windowed alarms. The first setpoint activates the alarm,
and the second setpoint deactivates the alarm (configuration for
‘Alarm as maximum’ type of alarm). Second setpoint must always
be higher in value than the first setpoint.
