Same as the direct action of the deviation high
limit when the SP ramp is not used. The
difference is that the SP ramp does not use the
current SP, but it uses the final SP. Same as the reverse action of the deviation
high limit when the SP ramp is not used. The
difference is that the SP ramp does not use the
current SP, but it uses the final SP.
Same as the direct action of the deviation low
limit when the SP ramp is not used. The
difference is that the SP ramp does not use the
current SP, but it uses the final SP. Same as the reverse action of the deviation
low limit when the SP ramp is not used. The
difference is that the SP ramp does not use the
current SP, but it uses the final SP.
