●Product handling
Installation
Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws and brackets may damaged.
If the tightening torque is insufficient, the product may be displaced and the mounting screws may come loose.
(Refer to page 15 "Mounting and Installation".)
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply.
Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the internal parts can result, causing malfunction.
Do not pull the lead wire forcefully, or lift the product by the lead wire. (Tensile force 49 N or less)
Hold the product body when handling, to prevent damage, failure or malfunction.
The tensile strength of the power supply/output connection cable is 50 N and the sensor lead wire with a
connector is 25 N.
For piping of the product, hold the piping with a spanner on the metal part of the product (Piping
attachment).
Holding other parts with a spanner leads to may damage the product.
Any dust left in the piping should be flushed out by air blow before connecting the piping to the product.
Otherwise damage or malfunction can result.
Refer to the flow direction of the fluid indicated on the product label for installation and piping.
Remaining air can cause inability to measure accurately.
Do not mount the body with the bottom facing upwards.
Retention of air can cause inability to measure accurately.
Avoid piping in which the piping size of the IN side of the product 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 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 piping port.
This can damage the sensor causing failure or malfunction.
Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
If there is a risk of foreign matter entering the fluid, install and pipe a filter or the mist separator at the
inlet to avoid failure and malfunction.
Otherwise damage or malfunction can result.
And it can cause inability to measure accurately.
Do not apply excessive rotational force to the monitor.
Rotating the monitor with excessive force will damage the end stop.
