6. FUNCTION AND DATA SETTINGS
IM 1E7B0-02E 6-11
6.3.9 Automatic Two Range Switching
• When an input exceeds 100% of the first range, the range is automatically transferred
to the second range and the status output changes state.
• P+, P– terminals are used for output connection.
P+, P– terminals are for common use with pulse, alarm and other status output
functions. Therefore, in case this function is used, other functions are not
available to use.
Display Description
Default : 10%
Default : 00
Automatic two range transfer can be selected “03” in
parameter No. “10”.
Forward second range can be set by calling up parameter
No. “33”.
Setting restrictions: First range
≤
2nd range.
Further second range span should be set in the same
number of places of decimals as first range span in
parameter No. “03”.
Example: First range : 1.000 then second range should be
4.000
Hysteresis width at switching range can be set in
parameter No. “34”.
It is the rate (%) of first range span.
