"Flow" identifier
The "Flow" identifier disappears when the
reed switch is closed, that is when the float
is in its uppermost position.
1. Disconnect the metering monitor cable
to temporarily disable the metering mon‐
itor.
2. Turn the rotary dial fully to the left ("-")
3. Enter the required operating pressure
on the discharge line, max. 10 bar.
4.
Only set the Flow Control initially to
a stroke rate of 90 Hz even on
pumps with speed control (stroke
control motor or frequency con‐
verter). The Flow Control then gen‐
erally operates faultlessly even at
stroke rates of up to 200 Hz, which
you can test after setting it.
Set a stroke rate of 90 Hz.
5. Reconnect the metering monitor cable.
The "Flow" identifier on the
ð
metering pump's LCD display goes
out with each pressure surge.
6. Slowly turn the rotary dial on the
metering monitor to the right ("+") until
the "Flow" identifier stops flashing.
7. Turn the rotary dial back a little until the
"Flow" identifier starts flashing again.
8. Use the frequency to set the required
capacity on the running pump.
9. Open the relief valve upstream of the
Flow Control; the "Flow" identifier should
stop flashing. If not, slowly turn the
rotary dial on the metering monitor to
the right ("+") again until the "Flow" iden‐
tifier stops flashing.
10. Close the relief valve upstream of the
Flow Control again and adjust it.
The "Flow" identifier should flash
ð
again.
