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).

Behavior in case of RSP input failure (p.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.
