Figure4.2.2 water-level sensors for deep well connecting wiring
Remark: When the actual water-level in the deep well is lower than the
horizontal line of low water-level, “S1” will be disconnected to “COM” as well as the
controller B6031ID(B2) will be displaying “A033” and will automatically stop the
pump to prevent the pump from idling. “S2” will not be connected to “COM” and the
controller B6031ID(B2) will not clear out fault “A033” until the actual water-level in
the deep well is higher than the horizontal line of high water-level. And then, the
controller B6031ID(B2) will automatically start the pump. Until the actual
water-level in the deep well is lower than the horizontal line of low water-level, “S1”
will be disconnected to “COM” as well as the controller B6031ID(B2) will be
displaying “A033” and will automatically stop the pump to prevent the pump from
idling. The controller B6031ID(B2) will automatically control the pump in this cycle
way.
2. Water-level sensors for upper reservoir connecting wiring
There are three signal leads of upper reservoir as given (Figure4.2.3) for
detecting water-level. The longest signal line is ①, which is corresponding to the
common port, is connected to the “COM” of controller B6031ID(B2). The signal line
②that is corresponding to the horizontal line of low water-level need to be connected
to the terminal “S3” of controller B6031ID(B2). The shortest line is ③, which is
corresponding to the horizontal line of high water-level is connected to the terminal
“S4” of controller B6031ID(B2).

B6031I Series Deep well Pump Inverter User Manual

Figure4.2.3 water-level sensors for upper reservoir connecting wiring
Remark: When the controller B6031ID(B2) cleared out fault “A033” (When
there is the water in the deep well) and the actual water-level in the upper reservoir is
lower than the horizontal line of low water-level, “S3” will be disconnected to
“COM” as well as the controller B6031ID(B2) will automatically start the pump and
the upper reservoir will be injected the water. Until the actual water-level in the upper
reservoir is higher than the horizontal line of high water-level, “S4” will be connected
to “COM” as well as the controller B6031ID(B2) will automatically stop the pump to
prevent water overflow . Until the actual water-level in the upper reservoir is lower
than the horizontal line of low water-level, “S3” will be disconnected to “COM” as
well as controller will automatically start the pump, and the upper reservoir will be
injected the water. The controller will automatically control the pump in this cycle
way.
4.2.2 Additional Remarks of Control Mode
1. the water-level of deep well and upper reservoir auto controlling
Please connect the water-level sensor of deep well and upper reservoir as shown
in Figure4.2.2 and Figure4.2.3 as well as setting the parameter b00.06=0.

4.3 Wiring Main Circuits
4.3.1 Wiring of Main Circuits
Figure4.3.1 High-performance main circuit wiring
4.3.2 Circuit Breaker
It is necessary to connect a suitable circuit breaker between 3 phase AC power
supply and B603 series intelligent constant water supply controller. The capacity of
breaker is 1.5~2 times to the rated current of controller.
4.3.3 AC Reactor (Optional)
In order to prevent the rectifier damage resulted from the large current, AC
reactor should be installed at the input side. It can also prevent rectifier from sudden
variation of power voltage or harmonic generated by phase-control load.
4.3.4 Input EMC Filter (Optional)
EMC filter can minimize the interference of the surrounding device which may be
disturbed by the cables when the controller is working.
4.3.5 Output EMC Filter (Optional)
EMC filter should be installed to minimize the leak current caused by the cable
and minimize the radio noise caused by the cables between the controller and motor.
4.3.6 Output Reactor
When the distance between the B6031I controller and motor is more than 50m,
the controller may be tripped by over-current protection frequently because of the
large leak current resulted from the parasitic capacitance with ground. So as to avoid
the damage of motor insulation, the output reactor should be installed.
