[27] Ab2 - Alarm 2 function
Available: When [36] AL2t is different from “nonE”.
Range: 0 to 3 with the following rule:
+1 = Not active at power up;
+2 = Relative alarm not active at set point change.
Note: For other details see [20] Ab1 parameter.
[28] AL2L - For High and low alarms it is the low limit of
the AL2 threshold
- For band alarm it is low alarm threshold
Available: When [26] AL2t is different from “nonE” or [26]
AL2t is different from “SE.br”.
Range: -1999 to [29] AL2H engineering units.
[29] AL2H - For High and low alarms it is the high limit
of the AL2 threshold
- For band alarm it is high alarm threshold
Available: When [26] AL2t is different from “nonE” or
[26] AL2t is different from “SE.br”.
Range: From [28] AL2L to 9999 engineering units.
[30] AL2 - Alarm 2 threshold
Available: When:
[26] AL2t = LoAb Absolute low alarm;
[26] AL2t = HiAb Absolute high alarm;
[26] AL2t = LodE Deviation low alarm (relative);
[26] AL2t = LidE Deviation high alarm (relative).
Range: From [28] AL2L to [29] AL2H engineering units.
[31] HAL2 - Alarm 2 hysteresis
Available: When [26] AL2t is different to “nonE” or [26] AL2t
is differ2nt from “SE.br”.
Range: 1 to 9999 engineering units.
Note: For other details see [24] HAL1 parameter.
[32] AL2d - Alarm 2 delay
Available: When [26] AL2t different form “nonE”.
Range: From oFF (0) to 9999 seconds.
Note: The alarm goes ON only when the alarm condition
persist for a time longer than [32] AL2d time but the
reset is immediate.
]rEG group - Control parameters
[33] Hi.Lo - Limit Control type:
Available: Aways.
Range: Hi = High limiter;
Lo = Low limiter
High limit control)
When a measured value (PV) exceeds a set point
(SP),“EXCEEDED” [EX]lamp lights, “OUT” lamp turns ON
and the limit output relay (Out 2) is de-energized.
“EXCEEDED” [EX] lamp turns off when PV goes into normal
condition, while the output [OUT] display lamp stays on as
it is (b). The output [OUT] display lamp turns off when a
confi rming operation (rearm) is done by an operator.
The way to confi rm are:
pressing
key or by DI1 (according to the <<diS>>
parameter setting).
The confi rming operation is not accepted during PV exceeds
SP (D) (during EXCEEDED lamp lights*). State of output
relay is de-energized whenever “OUT” lamp is on.
When the EXCEED lamp is ON but PV is lower than SP, the
upper display will be in green value and it shows that the PV
is in the hysteresis area
Low limit control
When a measured value (PV) exceeds a setpoint (SP),
“EXCEEDED” lamp (c) lights, and “OUT” lamp (b) turns ON .
The limit output relay is deenergizedthen. “EXCEEDED”
lamp turns off when PV goes into normal condition, while
the output (OUT) display lamp stays on as it is. The output
(OUT) display lamp turns off when a confi rming operation is
done by an operator.
The way to confi rm are:
pressing
key or by DI1 (according to the <<diS>>
parameter setting).
The confi rming operation is not accepted during PV exceeds
SP (D) (during EXCEEDED lamp lights*). State of output
relay is de-energized whenever “OUT” lamp is on.
When the EXCEED lamp is ON but PV is Higher than SP,
the upper display will be in green value and it shows that the
PV is in the hysteresis area.
[34] r.md - Limit output status at power ON
Available: Always
Range: on Limit output is ON in any case
oFF = Limit output is OFF at power on when PV
doesn’t exceed SP.
[35] HYS - Limit output Hysteresis
Available: Always.
Range: in Engineering units from 0 to 100 % of the input
spen.
