● Product handling
Installation
- Tighten to the specified tightening torque.
If the tightening torque is exceeded, the mounting screws and brackets may be damaged. Insufficient torque can
cause displacement of the product from its proper position and the looseness of the mounting screws.
(Refer to Mounting and Installation (page 16 to 21).)
- Be sure to ground terminal FG when using a switch-mode power supply that is commercially obtained.
- Do not use where the product is subjected to vibration or impact.
Otherwise damage to the internal components may result, causing malfunction.
Do not pull the lead wire forcefully, or lift the product by the lead wire. (Tensile strength 49 N or less)
Hold the product body when handling to prevent damage, failure or malfunction.
The product will be damaged, leading to failure and malfunction.
- When multiple sensors are used in parallel, the accuracy is deteriorated if they are mounted too closely
together.
For piping of the pressure switch, hold the piping with a tool on the metal part of the product (piping
attachment).
Holding other parts with a
Specifically, make sure that the
This will damage the connector.
- Any dust left in the piping should be flushed out by air before connecting the piping to the product.
Failure or malfunction may result.
- Ensure the flow direction of the fluid is aligned with the flow direction indicated on the product label
before installation and piping.
Avoid piping in which the piping size of the IN side of the switch changes suddenly.
If the piping size is reduced sharply or there is a restrictor such as a valve on the IN side, fluid velocity distribution
in the piping will be disturbed, leading to improper measurement. Therefore, the above-mentioned piping should
be connected on the OUT side.
If the OUT side is opened, or flow rate is excessive, cavitations may be generated, which may result in improper
measurement. As a measure against this, it is possible to reduce the cavitations by increasing the fluid pressure.
Take action such as mounting an orifice on the OUT side of the switch, and confirm that there is no malfunction
before handling.
If the orifice of the OUT side is fully closed to operate the pump, the switch may malfunction due to the effect of
pulsation (pressure fluctuation). Ensure that there is no malfunction before usage.
Do not insert metal wires or other foreign matter into the flow path.
This can damage the sensor causing failure or malfunction.
- Never mount the product in a place that will be used as a scaffold during piping.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
