1. Verify the color and terminal number when wiring.
Incorrect wiring can cause a switch to be damaged and may
result in a malfunction. Verify the color of wiring and the
terminal number in the instruction manual when wiring.
2. Avoid repeatedly bending or stretching the lead
wire.
Repeatedly applying bending stress or stretching force to the
lead wire will cause it to break.
3. Confirm proper insulation of wiring.
Make sure that there is no wiring insulation (contact with other
circuits, ground fault, improper insulation between terminals,
etc.). Overcurrent is flown and may result in a damage.
Operating Environment
Warning
1. Never use in an environment, where explosive
gases are used.
The switches do not have an explosion-proof rating. Never use
in an environment, where explosive gases are used, as this
may cause a serious explosion.
2. Mount a switch in such locations, where no
vibration or shock (less than 98 m/s 2 ) is affected.
1. Check regulators and the flow adjustment valves
before introducing the fluid.
If pressure or flow rate beyond the specified range are applied
to the switch, the sensor unit may be damaged.
[For air]
2. Fluids for measurement for this digital flow switch
are nitrogen and air.
Please note that accuracy cannot be guaranteed when other
fluids are used.
3. Never use flammable fluids.
4. Install a filter or mist separator on the upstream side
when there is a possibility of condensate and
foreign matter being mixed in with the fluid.
The rectifying device built into the switch will be clogged up
and accurate measurement will no longer be possible.
[For water]
5. Never use flammable fluids.
6. Install a filter in the inlet side when it is likely for
solid foreign objects to get mixed with fluids.

3. Use the switch within the specified fluid and
ambient temperature range.
Fluid and ambient temperatures are 0 ° to 50 ° C. Take
measures to prevent freezing fluid when below 5 ° C, since this
may cause damage to a switch and lead to a malfunction. The
installation of an air dryer is recommended for eliminating
condensate and moisture.
Never use a switch in an environment, where temperature
changes drastically even within the allowable ambient
temperature range.
Maintenance
Warning
1. Perform periodical inspections to ensure proper
operation of the switch.
Unexpected malfunctions and wrong operations may not
secure the safety.
2. Use caution when using a switch for an interlock
circuit.
When a pressure switch is used for an interlock circuit, devise
a multiple interlock system to prevent trouble or
malfunctioning. Verify the operation of the switch and interlock
function on a regular basis.
3. Do not disassemble or modify the main body.
