■ After maintenance is complete, perform appropriate functional inspections and leak
test.
Stop operation if the equipment does not function properly or there is leakage of fluid.
When leakage occurs from parts other than the piping, the product itself may be damaged.
Cut off the power supply and stop the fluid supply.
Do not apply fluid if the system is leaking.
Safety cannot be assured in the case of unexpected malfunction.
■ Handling Precautions
- Follow the instructions given below for selecting and handling.
● The instructions on design and selection (installation, wiring, environment, adjustment, operation,
maintenance, etc.) described below must be followed.
*Product specifications
- Use the specified voltage.
Otherwise failure or malfunction can result.
Insufficient supply voltage may not drive a load due to a voltage drop inside the product.
Check the operating voltage of the load before use.
- Do not exceed the specified maximum allowable load.
This may cause damage or shorten the lifetime of the product.
- Confirm the pressure loss at the sensor according to the flow rate characteristics (pressure loss) graph
before designing piping.
Confirm pressure loss of the sensor from the flow characteristics chart.
- Take care that pressure exceeding the specified range will not be applied due to water hammer.
<Examples of measures for reducing water hammer>
(1) Use a water hammer resistant valve.
(2) Use elastic piping material such as rubber hose etc. and an accumulator to absorb impact pressure.
(3) Shorten the length of piping as much as possible.
- Use the product within the specified operating pressure and temperature range.
- Proof pressure is 2MPa. Proof pressure depends on fluid temperature. Refer to the chart of the
operating pressure range.
- Reserve a space for maintenance.
When designing an application, allow sufficient clearance for maintenance and inspection.
