・No need to set anything when you
chose a analog output, Please do
not press or rotate anything.
・Do NOT use metallic screw driver to
rotate or press to set. Use a insulating
material, foe example a plastic screw
driver.
・Minimum setting values are:
5L=0.5L/min、10L=1.5L/min、30L=5L/min

！
Use relay with internal diode or external diode(D) to prevent damaging Photo
MOS-FET from back electromotive force as above when you use relay load.
E.g. V03C(HITACHI)
Remove the caps and you will see the volume and set button.
*you can set a alarm only when you chose a alarm output..
1. Power on (DC 24V) then LED (red or green) will be on.
2. Rotate the arrow with a plastic screw, for example, and set
a alarm value.
3. Press SET to confirm the settings. Micro computer inside of
the flow meter memories' it. To change the value, rotate
the arrow and press SET again.
*Do not need to reset the value after powered off.
4. Alarm is signaled with LED (D1).

【Power on】
This flow meter does not have a switch to power on.
Connect a red wire,+V and black wire,0V with 24V.
Then LED will be on.
Put quick fastener on the adapter until the adapters are locked between
the gap of the fastener. Make sure it is tightly locked.
And vice versa.

・Please beware of the direct load/pressure on the flow meter (PPS). It
could cause leaking or damages.
・Do NOT grab or press the cover very hard when you are connecting(plumbing)
