FY operation manual 42
11.3 Remote SV
Description
Remote SV functions as an analog signal (4~20mA or 0~10V) generated by external devices (EX: PLC AO module, transmitter)
to the Remote SV terminal of the controller, to change the SV with a preset range.
Remote SV signal selection: 4~20mA, 0~20mA, 0~5V, 0~10V, 1~5V, 2~10V

Examples
Input signal is K1 and its range is -50.0~600.0. When an external analog signal is input to the Remote SV
terminal, the signal will be based on the range presents linear display of SV parameters
When the signal input value is less than 2.4mA, the PV position shows nnn2, indicating that the signal of Remote SV is lower than
the lower limit value
When the signal input value is greater than 21.6mA, the PV position shows uuu2, indicating that the signal of Remote SV is higher
than the upper limit value
