INSTRUCTION MANUAL
①The type of pressure media for PG-35L should be used liquid and gas that don't corrode for SUS316L.
②For stability, use a regulated direct current power supply.
Surge absorbing devices（diodes,varistors, etc.）are necessary if inductive loads such as relays or solenoids are connected to the same
circuit as the PG-35L.
If using a DC power supply unit such as a switching power supply, the FG terminal should be earthed. Do not wire in parallel to high tension
cables or power lines, or use cable ducts which contain high tension cables or power lines.
③Be careful not to crimp any wires during handling, or put any pressure on the display area of the main body while assembling piping.
④Use pH neutral detergents to clean the body. Do not use solvents such as thinners.
⑤This product is dust proof and drip proof（IP65 of IEC standards）and is not suitable for use in environments requiring higher standards.
Also, do not use this product in an environment with a possibility of product being covered by liquids other then water（Such as oil, solvent,
and etc.）and outdoor.
⑥Do not use pointed objects such as pens to press the setting buttons on the display panel, as this may push holes in the setting buttons and
damage them.
⑦Do not insert wires, etc. in the pressure port, as this may damage the internal diaphragm and cause malfunctioning.
⑧gasket type:
Do not touch or scratch the edge of the fitting, as this may damage the sealing and cause leakage.
⑨The PG-35L do not have an explosion proof structure. Do not use it for the
detection of flammable gases.
⑩When analog output is supplied to a noise-sensitive device, a low-pass filter is
requested in a customer's circuit.
⑪Countermeasures for noise interference:
Please connect either the shield wire or the metal part of the product to frame
ground（FG）of the power source.
⑫In case a wire extension is needed, please use a shielded wire.
