5. FUNCTION AND DATA SETTINGS
5.5.9
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.
• PLS/ALM+, PLS/ALM–terminals are used for output connection.
PLS/ALM+, PLS/ALM–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.
Automotic two range transfer can be selected “03” in
parameter No. “b10”.
Forward second range can be set by calling up parameter
No. “b33”.
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. “b03”.
Example: First range : 1.000 then second range should be
4.000
Hysteresis width at switching range can be set in
parameter No. “b34”.
It is the rate (%) of first range span.
When using reversed status (ON/OFF) is required,
it can be set in
“N02 Output Mode”.
