continue SETTING AND OPERATION
5.4 Backwash
5.6 Auto-Inverter Mode
Start the Backwash procedure by pressing the backwash button
(). Once activated the timer will start to count down on the
main screen. Use to change the length of backwash time
required.
5.5 Manual-Inverter Mode
Under Auto Inverter Mode, the pump can automatically detect
the system pressure and adjust the speed of motor to reach
the set flow.
Exit backwash:
When backwash mode is on, user can hold for 3 seconds to
exit, the pump will return to the previous state before backwash.
If aspeed limitis set by the user, the running capacity of the
backwash will not exceed the set speed limit. (see 5.9)
Note:
When the pipeline pressure is too high, to maintain an adequate
flow rate, user can set the running capacity to 105%-120%.
The pump will run at a higher speed but will not exceed the rated
power of each model. If the pump has reached the rated power at
105% and user continues to increase the running capacity, the
display will return to 105% when the motor speed is stabilized.
Press or to adjust from 0 to
1500s with 30 seconds for each step.
80~100%, enter the parameter setting
(see 5.10)
5.7 Timer mode
The pump’s on/off and running capacity could be commanded by
timer, which could be programmed daily as needed.
Enter timer setting by pressing .
Press or to set the local time.
Press to confirm and move to time-1 setting
Press or to choose the desired running periods,
running capacity or flow rate (when % icon is flashing,
user can change to set the flow rate by pressing .
Repeat above steps to set other 3 timers.
Hold 3 seconds to save settings and active timer mode.
Unlock the screen, press to switch from the
Manual-Inverter mode to Auto-Inverter mode.
Press to switch to Manual-Inverter mode.
Press again to switch to Auto-Inverter mode.
Press or to set the running capacity between
30%~120%, each step by 5%.
Press to start. The pump will run at 80% of the
running capacity at the initial startup after the
self-priming.
Theflow rate could be adjusted, by pressing or
with 20L/min for each step.
The unit of flow rate could be changed to LPM, IMP
GPM or US GPM, by pressing bothfor 3
seconds (default is L/min).
or Check 4 timers to make sure there is no invalid
setting.
NOTE:
When timer mode is activated, if the set time period contains the
current time, the pump will start running according to the set running
capacity or flow rate. If the set time period does not contain the current
time, the timer number (or 1 or 2 or 3 or 4) that is about to
startrunning will be displayed on the controller and flash,
will display the corresponding timeperiod, indicating a successful
timer setting.
All 4 time periods should be set in chronological order. Overlap setting
of time will be considered as invalid, the pump will only run based on
the previous validsetting. If all 4 time periods set by the timer areinvalid,
and will flash to remind the user, you can press
to reset the time period again to makesure they are valid.
During timer setting, if you want to return to the previous setting, hold
both for 3 seconds. If you don’t need to set all 4 timers, you can
hold for 3 seconds, the system will automatically save the current
set value and activate the timer mode.
Self-learning:
Refer to page5 for the default adjustable flow range for InverFlow Pro.
When firstswitching to the Auto-Inverter mode manually or via
external control or activating timer mode with flow rate setting,
the system will perform the self-priming process (see 5.3) and
then the self-learning process for 180s and redefine the adjustable
flowrange of the pump by detecting the pipeline pressure.
eg: the default adjustable flow range of Inverflow P300i is
80-420 L/min after self-learning, the range may be redefined to
110-320L/min. If the set flow is beyond the current adjustable
range, the actual achievable flow rate will be displayed after the
motor speed is stabilized.
Note:
After the firstself-learning, the pump will redefine the adjustable flow
range. The pipeline pressure will be recorded by the system after the
pump runs at the set flow/capacity for 5 minutes without other ope-
rations. During the pump running, if itis detected that the pipelin
pressure changes beyond a certainrange, the icon of % or L/min (or
other flow units) symbol will flashfor 5 minutes. If the change last for
5 minutes, the pump will perform aself-priming and self-learning
process, and redefine the flow range accordingly.
After the redefinition of the flow range, the pump will automatically
adjust the running capacity to reach the set flow.
User can set the timeinterval to trigger the self-leaning automatically in
the parameter setting (see 5.10) to ensure the accuracy of the flow rate.
