2. A “Latched alarm” (manual reset) is an alarm
that will remain active even if the conditions that
generated the alarm no longer persist. Alarm
reset can be done only by an external command
(U button, digital inputs or serial link).

3. An “Acknowledgeable” alarm is an alarm that can
be reset even if the conditions that generated the
alarm are still present. Alarm acknowledge can
be done only by an external command (U button,
digital inputs or serial link).

4. - The instrument does not memorize in EEPROM
the alarm status. For this reason, the alarm sta-
tus will be lost if a power down occurs.
[25] AL1L - For High and low alarms, it is the low
limit of the AL1 threshold
- For band alarm, it is the low alarm
threshold
Available: When [23] AL1t is different from “nonE” or [23]
AL1t is different from “SE.br”.
Range: From - 1999 to [26] AL1H (E.U.).
[26] AL1H - For High and low alarms, it is the high
limit of the AL1 threshold
- For band alarm, it is the high alarm
threshold
Available: when [23] AL1t is different from “nonE” or [23]
AL1t is different from “SE.br”.
Range: from [25] AL1L to 9999 (E.U.).
[27] AL1- Alarm 1 threshold
Available: When:
- [23] AL1t = LoAb Absolute low alarm
- [23] AL1t = HiAb Absolute high alarm
- [23] AL1t = LodE Deviation low alarm (relative)
- [23] AL1t = LidE Deviation high alarm (relative)
Range: From [25] AL1L to [26] AL1H (E.U.).
[28] HAL1 - Alarm 1 hysteresis
Available: When [23] AL1t is different from “nonE” or [23]
AL1t is different from “SE.br”.
Range: From 1 to 9999 (E.U.)
Note: The hysteresis value is the difference between the
Alarm threshold value and the point where the Alarm
automatically resets.
[29] AL1d - Alarm 1 delay
Available: When [23] AL1t different form “nonE”
Range: From oFF (0) to 9999 seconds
Note: The alarm goes ON only when the alarm condition
persists for a time longer than [29] AL1d time but the
reset is immediate.
[30] AL1o - Alarm 1 enabling during out of range
indications
Available: when [24] AL1t different from “nonE”
Range: No = Alarm NOT running when out-of-range
conditions are detected.
YES = Alarm enabled when out-of-range condi-
tions are detected.
]AL2 Group - Alarm 2 parameters
[31] AL2t - Alarm 2 type
Available: Aways
Range: nonE = Alarm not used
LoAb = Absolute low alarm
HiAb = Absolute high alarm
LHAb = Absolute band alarm
SE.br = Sensor break
[32] Ab2 - Alarm 2 function
Available: when [31] AL2t is different from “nonE”
Range: 0 to 15 with the following rule:
+1 = Not active at power up.
+2 = Latched alarm (manual reset)
+4 = Acknowledgeable alarm
Example: setting Ad2 equal to 5 (1+4) the alarm 2 will be
“not active at power up” and “Acknowledgeable”.
Note: For other details see [24] Ab1 parameter.
[33] AL2L - For High and low alarms, it is the low
limit of the AL2 threshold
- For band alarm, it is is the low alarm
threshold
Available: When [31] AL2t is different from “nonE” or [31]
AL2t is different from “SE.br”.
Range: From - 1999 to [34] AL2H (E.U.).
[34] AL2H - For High and low alarms, it is the high
limit of the AL2 threshold
- For band alarm, it is the high alarm
threshold
Available: When [31] AL2t is different from “nonE” or [31]
AL2t is different from “SE.br”.
Range: From [33] AL2L to 9999 (E.U.).
