Low Flow Cut Off
- Assign
AUTO - OOS Use this function to assign the switch point for the low flow cut off.
Options:
OFF
VOLUME FLOW
Factory setting:
OFF
Low Flow Cut Off
- On Value
AUTO - OOS Specifies the switch-on point of the low flow cut off. Low flow cut
off is active if the setting is a value not equal to "0".
User input:
5-digit floating-point number
Factory setting:
0.0000
Note!
• A flow value of "0" is output via the output value OUT (AI Block)
when the low flow cut off responds. In addition, the status
changes to UNCERTAIN.
• The unit used is displayed in the “Low Flow Cut Off - Unit”
parameter and determined in the “System Unit - Volume Flow”
parameter, (see Page 110).
Low Flow Cut Off
- Unit
read only Displays the unit for the low flow cut off.
Note!
The unit for the low flow cut off is determined by means of the
“System Unit - Volume Flow” parameter, (see Page 110).
Low Flow Cut Off
- Off Value
AUTO - OOS Specifies the switch-off point of the low flow cut off. Enter the
switch-off point as a positive hysteresis from the switch-on point.
User input:
0...100%
Factory setting:
50%
Example:
Low Flow Cut Off Assign = VOLUME FLOW
Low Flow Cut Off Off-Value = 50%
Low Flow Cut Off On-Value = 10
Low Flow Cut Off Unit = l/s
This results in an off-value of 15 l/s
(10 l/s + [10 l/s · 0.5] = 15 l/s).
