Setting Control Specifications Section 4-3
Note (1) When this parameter has been changed, the new setting becomes effec-
tive the next time a software reset is performed for the Unit or the next
time power is turned ON.
(2) The remote SP function can be used for channel 1 or channel 2 for the
TC4, but only for channel 1 for the TC2.
!Caution
• If autotuning starts during remote SP operation, autotuning will be executed
with the SP that existed when autotuning started. After autotuning is com-
pleted, control will start based on the remote SP value.
• The remote SP cannot be used as a reset condition for a standby sequence.
• Effective Range of the Remote SP
The following diagram shows the internal SP that will actually be used in
control if the remote SP's range is wider than the input range or SP limiter
range.
Local SP Sets the selected bank's set point.
Remote SP Sets the process value of the channel specified as the remote SP input.
Internal SP This is the set point actually set for use in control.
