Instruction Manual
Important Information and Warnings
①Select either the PG-30 or the PG-35 depending upon the type of pressurized media.
②The maximum impressed pressure of the PG-30-102R at the time of vacuum break is 500kPa.
③For 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-30/PG-35.
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.
④Be careful not to crimp any wires during handling, or put any pressure on the display area of the main body while assembling piping. The
fitting torque of sealing screws and M5 fitting screws should be 3.0N･m maximum.
⑤Use pH neutral detergents to clean the body. Do not use solvents such as thinners.
⑥This product is dust proof and drip proof (to IP65 of IEC standards) and is not suitable for use in environments requiring higher
standards.
⑦Do 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.
⑧Do not insert wires, etc. in the pressure port, as this may damage the internal diaphragm and cause malfunctioning.
⑨PG-35 G3/8 type:
Do not touch or scratch the diaphragm at the edge of the fitting, as this may alter the performance characteristics or damage the
diaphragm, and cause malfunctioning.
⑩PG-35 gasket type:
Do not touch or scratch the edge of the fitting, as this may damage the sealing and
cause leakage.
⑪The PG-30/35 series do not have an explosion proof structure. Do not use it for the
detection of flammable gases.
⑫When analog output is supplied to a noise-sensitive device,a low-pass filter is requested
in a customer's circuit.
⑬Counter measures for noise interference.
Please connect the shielded wire of this product to FG terminal of the power line. （The
shield wire is connected with the metal part inside of the product.）
