M1 M2 GND +VO AI
2.Set pressure parameters:
P0.38=1
P0.03=10
P0.04=1
P0.05=24
3.Set target pressure:
P0.00=3.0
P0.01=0.3
4.Choose auto-start mode:
P0.14=11
5.Check rotation direction
of pump:
Shortly start pump, check
the direction of pump, if
the pump direction error,
change the pdrameter
P0.02.
6.Observe the effect of
constant pressure:
Observe the effect of
constant pressure, if the
pressure is constant, that is
OK; if the pressure
fluctuations large , please
reference common fault
handling tutorial.
8.Warm tips
a: Water supply system
must be equipped with a
check valve, five way valve
is a kind of check valve.
b: For a new pump,when it
runs without pressure,
emptying is suggested.
