RSP filter
This RSP filter is a primary delay filter to be used if the RSP deflects finely due to
effect of the noise. As this set value is made larger, the RSP to be used for control
of this unit becomes difficult to change. Normally, the RSP filter is used with the
initial value (0.0).
• When the model provides the RSP input, the display and setting can be
performed.
OUT = OUT
-1
+ (IN – OUT

)/(T/ Ts +1)
IN: Input to the filter
OUT: Current filter calculation output
OUT

: Previous filter calculation output
T: Filter set value (second)
Ts: Sampling cycle time (0.1s)

RSP low limit/high limit and RSP low limit/high limit alarms
The RSP low limit and RSP high limit are provided for each RSP input type.
Basically, -10%FS of each range is the RSP low limit and +110%FS of each range
is the RSP high limit.
For details, refer to;
■
Behavior in case of RSP failure (on page 10-4)
.
The RSP is limited so that it is in a range from the RSP low limit to the RSP high
limit. If the RSP before the RSP ratio, RSP bias, and RSP filter are activated is
larger than the RSP high limit in the RSP mode, the RSP high limit alarm (AL05)
occurs. If this RSP is smaller than the RSP low limit, the RSP low limit alarm
(AL06) occurs. (Both the RSP high limit alarm and RSP low limit alarm do not
occur in the LSP mode.) When the RSP is used as SP in the RSP mode, the
limiting with the SP low limit and SP high limit also becomes valid.
■
RSP and LSP1 to 8
The RSP display and eight groups of LSP setup values can be set.
• When the model provides the RSP input, the RSP can be displayed and set.
• The display and setting can be made for the LSP system group selected in [C30:
LSP system group].
