INPUT-OUTPUT RELATION EXAMPLES

• FS

-FS stands for 0 % of the input range configured by ITEM 06. +FS stands for +100 % of the input range, configured by ITEM 07.

• 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.
