@ Each pump with rated horsepower should match the automatic
control box with the same horsepower.
@ Do not expose the control box to the strong sunlight or get it
wet by rain. Put it in a well-ventilated place, and avoiding strong
@ The live wire of three-phase power should go through on-off
switch, the zero wire can go through directly.
@ Fuse requirement: Fusing current = rated current X (l. 5 ~2).
@ The water-level control of headwaters and water tower needs only
an electrode conducting wire and a return conducting wire. The
upper and lower limits of the water level can be differentiated by
special "level divider". One side of it has a conducting wire,
which should be connected with the terminal of "well electrode" or
"tower electrode"; The other side has two conducting wires, of
which the short one is the water-level upper limit conducting wire,
while the long wire is the water-levellower limit conducting wire.
Both conducting wires can be connected with electrode detector
Respectively and be put at the required water levels. If the
electrode cannot reach the required depth, the conducting wire can
be lengthened. The return electrode must be placed under upper and
@Short circuit shou1d be avoided between various conducting wires,
electrode, and the wall of the well or tank.
@"Well Electrode" could not be installed if water is sufficient,
The water level wil1 never be lowered to the intake of the pump,
but the micro switchette on the upper part of the main circuit
board should be turned to "right" (or connect terminal "well
electrode" with "return electrode"), otherwise he switchettt should
be turned to "left".
@ The APP1ication of functions:
(1) Waterleve1 automatic contro1 with electronic protection: Turn
the micro switchette on the upper part of main circuit board to
"right "--water level automatic control status. Then. Turn the main
switch on the faceplate to "left "--electronic protection status.
(2) Manual control with electronic protection: Turn the micro
switchette on the main circuit board to "left"--manual control
status, the main switch on the faceplate remains at" left"
(3) Relay protection: Turn the main switch on the faceplate to
"right". Thus the maincircuit board is out of function.
(4) Electronic protection should be used first.
(5) Test phase vacancy and overloading:
On the lower right part of the main circuit board there are four
micro buttons, which the top one is overloading test button, the
1ower three are phase vacancy test buttons. If the pump is working
normally, press anyone of the four buttons fixedly, the automatic
switch in the box will be automatically cut off within 5 seconds
and self-locked. This indicates the protection function is OK. Each
time after the switch is turned off, reset it first, turn the main
switch to "stop" position, and wait for l5 seconds, the machine can
be turned on again.
(1) Relay protection will function whenever a function has been
chosen, but because itssensitivity is lower than electronic
protection, electronic protection wil1 be a top
Priority ensuring double protection.
(2) 15 seconds will be required if restarting the machine when
using electronic protection. Otherwise the "Memory" function will
work, resulting in false overloading protection and the machine
will be stopped. This is not a fault. Stop the machine for l5
seconds, and then restart it, everything wil1 be ok.&
