HP Limit
(High Pressure Limit)
高压限值
It determines the threshold for
the EVENT 4 (see Section 5.1).
See Section 6.1 for the Analog
Input precision.
2.0-1000.0 bar
90.0 bar
R/W
Local, Serial,
Modbus.
LP Limit
(Low Pressure Limit)
低压限值
It determines the threshold for
the EVENT 2 (see Section 5.1).
See Section 6.1 for the Analog
Input precision.
It must be lower than “Pressure Max”
and lower than “HP Limit” otherwise a
CONF Alarm is generated
(see Section 6.4).
0.0-1000.0 bar
30.0 bar
R/W
Local, Serial,
Modbus.
Drop Enabled
压降速率启用
If set as “Yes” EVENT 5 and EVENT 6
are managed by the ELBS-20
(see Section 5).
If set as “No” EVENT 5 and EVENT 6
are not considered by the ELBS-20. It
means that EVENT 5 is not stored and
does not cause the Safety Action and
that EVENT 6 is not stored.

VLC PDR
(Valve Control
Pressure Drop Rate)
控制模式压降速率
It is the Pressure Drop Rate in VC and
VC+ACQ operating mode. It determines
the threshold for the EVENT 6
(see Section 5.1).
For correctly setting this
parameter, see Section 6.1.
0.1-999.9 bar/min

D.ACQ PDR
(Data Acquisition
Pressure Drop Rate)
采集模式压降速率
It is the Pressure Drop Rate in
ACQ mode.
It determines the threshold for the
EVENT 5 (see Section 5.1).
For correctly setting this
parameter, see Section 6.1.
0.1-999.9 bar/min
3.0

S.Rate
(Sampling Rate)
采样频率
It is the sampling rate (Pressure and
optionally Position) that is used during
the VC, VC+ACQ e ACQ Operating
Modes (see Section 5.1.1).
It must be set at least at 5.0 if “V.Ext.
Applied” = “No”, otherwise a CONF
Alarm is generated
(see Section 6.4).

and optionally Position) that is used
during the SLOW operating mode
(see Section 5.1.1).
