Input Explanation
1.1.1 OUTPUT B1 INACTIVE
FLOW.VAL B1 Flow value switching point.
The switching point is entered in flow units.
If the current flow value exceeds this set switching point, then output B1
is activated.
Note:
The function NC or NO can be selected using menu 3.3.
COUNTER.VAL
B1
Counter value switching point.
Each positive number can be set here.
If the counter exceeds this value, then output B1 is activated.
Note:
The function NC or NO can be selected using menu 3.3.
1.1.2 OUTPUT B1 HYST.B1 Hysteresis setting for the flow value switching point.
Value range 0...switching point.
Example, if a switching value of 200 is set under 1.1.1, then a hysteresis
value of 0...200 can be set here.
If the value 0 is entered here, then this output does not have hysteresis.
If the value 20 is entered here, then the output functions as follows:
If the current flow value exceeds the value 200, then the output switches
3.
If the current flow value drops below the hysteresis value of 180, then the
switching output returns to its normal state 4.
Note:
To invert the operating method, use menu 3.3 to set the output from NO
1 to NC 2 or vice versa.
This function is not activated on the counter switching point.
