Using a Remote SP Section 4-23
4-23 Using a Remote SP
The remote SP function scales a remote SP input (4 to 20 mA) to the remote
SP upper and lower limits, and takes it as the set point. (This function is sup-
ported by the E5AN-H and E5EN-H only.)
Set the Remote SP Enable parameter (advanced function setting level) to ON,
and use an event input or an operation command to select the remote SP.
Precautions
When the ST (self-tuning) parameter is turned ON, the SP Mode parame-
ter is forcibly set to LSP.
The remote SP input is not accepted during autotuning. Autotuning is exe-
cuted for the remote SP at the beginning of autotuning.
Changes in the remote SP value are not used as conditions for resetting
the standby sequence.
Remote SP Scaling
The remote SP input (4 to 20 mA) can be scaled to match the PV input
range, based on the Remote SP Upper Limit and Remote SP Lower Limit
parameter settings.
The remote SP input can be input in a range of 10% to 110% of 4 to 20
mA. Input values outside of this range treated as out-of-range input val-
ues (RSP input error) and clamped to the upper or lower limit. In SP
mode, the RSP single indicator will flash, and in local SP mode the No. 2
indicator for the Remote SP Monitor will flash.
An alarm can be output if an RSP input error occurs by setting the
Remote SP Input Error Output parameter to ON.
