ASSIGN LOW FLOW
CUT OFF
(6400)
Use this function to assign the switching point for low flow cut off in a technical
engineering unit.
Options:
OFF
VOLUME FLOW
Factory setting:
VOLUME FLOW
ON-VALUE LOW FLOW
CUT OFF
(6402)
Use this function to assign a value to the switch-on point for low flow cut off.
Low flow cut off is active if the value entered is not equal to 0. The sign of the
flow value is highlighted on the display to indicate that low flow cut off is active.
User input:
5-digit floating-point number
Factory setting:
Depends on country, [value] / [dm³...m³ or US-gal...US-Mgal]
Corresponds to the factory setting for the low flow cut off, (see Page 76 ff.).
 Note!
The appropriate unit is taken from the UNIT VOLUME FLOW (0402) function,
(see Page 15).
OFF-VALUE LOW FLOW
CUT OFF
(6403)
Entry of the switch-off point (b) for low flow cut off.
Enter the switch-off point as a positive hysteresis (H) from the switch-on point
(a).
User input:
Integer 0...100%
Factory setting:
50%
Example:
Q = Flow [volume/time]
t = Time
a = ON-VALUE LOW FLOW CUT OFF (6402) = 200 dm³/h
b = OFF-VALUE LOW FLOW CUT OFF (6403) = 10%
c = Low flow cut off active
1 = Low flow cut off is switched on at 200 dm³/h
2 = Low flow cut off is switched off at 220 dm³/h
