No operations to buttons on the controller within 1 minute, button
lock indicator light on which represent buttons are locked. Before
operation press and hold the “ ”and“ ” buttons for 5 seconds to
unlock. This function can avoid incorrect operation.
Interval backwash times (Suitable for F68)
It could set up interval backwash times for F68 up-flow regeneration
valve which means several times of services but one time of backwash.
The setting of interval backwash time depends on the local water
turbidity. (The lower the turbidity is , the longer of the interval backwash
time can be set)
It can choose time clock type or meter type by program
selection
When all symbols light no, press and hold and buttons for 5
seconds to enter the menu of valve model selection. Please set the
program type in accordance with the product type. (Tim clock type by
days or hours or meter type) (Notice: The meter type product has one
flow meter and flow meter cable, but the time clock type doesn’t have).

There are two kinds of regeneration modes for time clock type
When the program is set as time clock type by days (such as F63C1,
F68C1, etc.) it can be changed to be by hours by dialing the red switch
on main control board to “1” (Refer to the Figure 13). Pointing to “ON”
means the time clock type service by days.(attention: After dialing the
switch, please restart the power)
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 refer to Figure 3-9)
Signal output
There is a signal output connector on the main control board. It is for
controlling external wiring (Refer to Figure from Figure3-1 to Figure
3-8).
There are two kinds of output modes:
b-01 Mode: Turn on start of regeneration and shut off end of
regeneration; b-02 Mode: Signal 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 refer 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 booster pump was 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 refer to
Figure3-10)
Maximum interval regeneration days
Under the situation of service reaching the setting days and the
volume not yet, it could enter into regeneration process forcibly when
current time is the same as regeneration time.
All parameters can be modified
According to the water quality and usage, the parameters in the
process can be adjusted.
