Wiring (interface)

【cable functions】

Sign| Color| Name| Direction| Characteristic| Output selection| Operation and usage
---|---|---|---|---|---|---
VCC| Red| Connect +| JPSL ← Equipment| DC24V±10％| | Connect +side of power supply.
Supply +24V to JPSL.
G| Black| Connect –| JPSL ↔ Equipment| | | Connect -side of power supply.
It is GND(0V) of JPSL.
It is -line of analog output.
AOUT| White
＊| Analog output| JPSL → Equipment| 0～10V| ※ Choose one of two outputs.| Flow rate is changed to the electric signal and transmitted to the device.
+line is for analog output.
4～20mA
ALM| Yellow
＊| Alarm output| JPSL ← Equipment| Photo MOS FFT( A )| ※ Choose one of two outputs.| Alarming signal to equipment.
(A) flow rate ≧ alarm value : ON
(B) flow rate ＜ alarm value : ON
Photo MOS FFT( B )
CM| Blue
＊| Alarm return| JPSL → Equipment| No need of earth (COM)| | Alarm output return circuit. Independent from GND

Default setting is one of outputs at the time of shipment.
White wire is spare wire when alarm output, yellow and blue are spare wires when analog output.
Contact between the spare wires or between wires and external equipment could cause accident or damage. Please insulate each wire when used.

Caution
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)

Procedures

The diagram below shows a control panel on the top of the body

Take a cap out
Set a alarm value with a screw
Press a set button.
LED light confirms the Deviation from set value.

【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.

Alarm settings

<table 1> explains definition of alarm output and LED. While ordering select only one output
Remove the caps and you will see the volume and set button.
you can set a alarm only when you chose a alarm output..

Power on (DC 24V) then LED (red or green) will be on.
Rotate the arrow with a plastic screw, for example, and set a alarm value.
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.
Alarm is signaled with LED (D1).

<table 1>
Description of alarm output and LED lights

*A internal circuit of alarm output is MOS-FET. ON: conduction and OFF: No conduction

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

【Indication of divisions】|

Point the arrow towards the setting value

Note: There is only the numbers from 0 to 10 on the volume. Please set the value referring to this diagram.

Connections

※ At the time of shipment adapters and quick fastener has enclosed separately.

Adapter is Rc3/8 female. Keep the adapter hold and screw the fitting.
When you install our product between the hard plumbing, use hose or flexible tube to keep the center core straight.
Insert an adapter into a body. There is O ring, P14, around the adapter. Please pay attention to attach properly with no any particle in between
Put quick fastener on the adapter until the adapters are locked between the gap of the fastener. Make sure it is tightly locked.

A straight pipe length needs min. 7D on upper stream and 5D on down stream to keep the accuracy.
Please do not do the plumbing (Put and orifice) sudden changes in the size of piping upstream.
Install valves, bifurcations, gages etc. on down stream.
D=adapter size, 5L: 4.1mm, 10L: 5.8mm, 30L: 10mm
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)
