The Setting Step
1. If the flow range needs to be reseted, please open an upper cover at first and relax the
revolvable cam(2) with the hexangular key wrench(d). (as diagram B)

2. Turn the flow pointer(5) to the requested alarm set point with hand and hold the hand
at the position (as diagram C). Let the revolvable cam touch the micro switch(1) to cause NO, COM

3. Revolve the flow pointer(5) by hand and confirm the alarm setting whether it is correct by multimeter(a) once again.
4. If the alarm set point still incorrect, please repeat 1,2,3 steps until reach the alarm set point that you need.
5. Finally, move the alarm pointer to the alarm of new setting point and lock tightly by "+" driver with hand.
6. If the pointer didn't return zero (as diagrm E), when there are not fluid through inside this flow meter.

Notice
1. Please watch for the flow direction when you install.
2. After setting completon, please indeed lock the upper cover tightly, and have to a cable gland in
entrance fixed cable to make sure water tightly.
3. If the fluid is dirty water or waste water, please installing filter at inlet to avoid fluid jamp.

Program Steps Method
Step 1. The junction terminal of program communicator with the circuit board as Fig. A. Then proceed to under steps.
Step 2. Press and hold down the RESET button for 5 seconds, the LED lamp will light. Then release press and to
keep indicating pointer on “0” point of scale. Then press SET button to start proceed another step. LED
lamp will become dark.

Step 3. To move indicating pointer to 10% of full scale, LED will flashing once on intermittence.
Then, press SET button and start another steps.
Step 4. To move indicating pointer to 20% of full scale, LED will flashing twice on intermittence.
Then, press SET button and start another steps.
LED Flashing Once LED Flashing Twice
LED Flashing Three Times LED Flashing Four Times
Step 5. To move indicating pointer to 40% of full scale, LED will flashing three times on intermittence.
Then, press SET button and start another steps.
Step 6. To move indicating pointer to 60% of full scale, LED will flashing four times on intermittence.
Then, press SET button and start another steps.
LED Flashing Five Times LED Flashing Six Times
Step 7. To move indicating pointer to 80% of full scale, LED will flashing five times on intermittence.
Then, press SET button and start another steps.
Step 8. To move indicating pointer to 100% of full scale, LED will flashing six times on intermittence.
Then press SET button, LED will become dark. At the meantime, the proceedure of program sets
are finished.

Step 9. After completion the above-mentioned steps, plesae check of the flow rate 0~100% compare with the output signal
4~20mA or not. If output signal can’t match to the flow indicator as under flow table of step 10, it should be re-set
again according to
Program Steps Method.

Note
1. Above all, please confirm the input power supply and the wiring mode that are correct.
2. After setting completion, please indeed lock the upper cover tightly, and have to a cable gland in entrance
fixed cable to make sure water tightly.
3. If the process of program set is error, please press and hold down the SET button until the LED lamp turns off.
Then re-set it again according to
Program Steps Method.
4. Moves the indicator by manual and test run directly after the flow meter completion of installed, all of they are workable.
5. The flow meter has completed program before shipping, therefore it doesn’t need to program once more.
