INPUT-OUTPUT RELATION EXAMPLES

• FS
-FS stands for -15 % of the input range, which is configured by ITEM 22, 0 % input voltage/current and ITEM 23, 100 % input voltage/current. +FS stands for +115 % of the input range.

• OVF
When one of the following conditions is true, the digital output overflows (OVF).
 1) When the input signal is out of the range between -FS and +FS.
 2) When the display value (= output signal) exceeds the display range.
 The display range differs according to output code. For example, in case of BCD with polarity, it is -9999 to 9999. Please refer to the instruction manual for detail.
