Interlock function
It has a function of interlock to realize only one valve in regeneration
but the other valves are in service while several valves parallel in system.
In multi-steps treatment systems such as RO pre-treatment, when several
valves are in series, there is only one valve in regeneration or washing to
ensure pass water all the times while different valves in regeneration or
washing.(Application refers to Figure 3-9)
Control signal output
There is a signal output connector on main control board. It is for
controlling external wiring (Refer to figures from Figure3-1 to Figure 3-8).
There are two kinds of output modes: b-01 Mode: Turn on at the start
of regeneration and shut off at the end of regeneration; b-02 Mode: Signal
is available only at intervals of regeneration cycles and in service.
Remote handling input
This connector can receive external signal, used together with PLC,
and computer etc. to control the valve. (Application refers to Figure3-11)
Pressure relief output
The valve will cut off feeding water to drain line when it switches in
regeneration cycles (Same as signal output b-02). Thus in some water
treatment system, e.g. deep well, one diaphragm booster pump was

MODEL 51240B/53540B/53640B/61240B/63540B/63640B
5
installed on the inlet to increase the system water feeding pressure, this
cut-off will cause pressure on inlet rising too fast to damage the valve.
Pressure relief output can be used to avoid this problem. (Application
refers to Figure3-10)
All parameters can be modified
According to the water quality and usage, the parameters in the
process can be adjusted.

B. When the flow meter stops measuring but the tested liquid still flow, it
can check the work mode of probe online. Screw the probe nut A out,
and check the working condition of the diode on the back of probe. If the
diode always light on or off, it indicates the impeller in pipeline stop
rotating. It shall stop pipeline working, release pressure in pipeline, and
dissemble the probe to check if there is any foreign matter impact
impeller rotating. After cleaning, if it can rotate normally by manually,
and the diode works normally, it can continue to use after confirming the
installation correct.(As Figure 1-3)
C. If the probe has impeller broken, the top bracket of probe damaged,
bearing bended, after repairing but still unable to free rotation or the
wetted part has corrosion, or the installation screw thread serious
damaged, it shall replace a new probe.
D. If the diode on the back of probe works normally, but the display
board shows incorrect, please check if the probe wire has any damage
and use a multi-meter to check the voltage between shielding and black
wire if normally. If the diode light on, there is no voltage output; and if
the diode light off, there is voltage output.
