PDM20-Transmissible pressure gauge wiring diagram
M1 M2 GND +VO AI
Before connecting, check the
voltage bVO and GND
using a multimeter
1.Installation and wiring:
Connect the power cable
and the sensor cable
according to the diagram
.
2.Set pressure parameters:
P0.38=1;
P0.03=10;
P0.04=0;
P0.05=6
3.Set target pressure:
P0.00=3.0;
P0.01=0.3
4.Choose auto-start mode:
P0.14=11
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.
7.Sleep test:
Close the water outlet, the
drive output frequency will
be reduced until shutdown;
if it can not sleep, please
refer to the common fault
handling tutorial.
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.
5.Check rotation direction
of pump:
Shortly start pump, check
the direction of pump, if
the pump direction error,
change the pdrameter
P0.02.
