Important Information and Warnings
①Non-corrosive gases should be used as pressure media for PS30.
②The maximum applicable pressure for the PS30-102R at the time of vacuum break is 500kPa.
③Always carry out wiring work with the power off.
④For stability, use a regulated direct current power supply.
Surge absorbing devices (diodes, varistors, etc.) are necessary if inductive loads such as relays and solenoids are connected to the same
power line as the PS30. Do not wire in parallel to high voltage cables or power lines, or use the same cable ducts which contain high
voltage cables or power lines.
⑤Check fluctuations in power voltage so that the power input cannot exceed the rating.
⑥Be careful not to apply force to any wires during handling, or apply force to the display area of the main
body during piping.
⑦Use pH neutral detergents to clean the body. Do not use lacquer thinner and other solvents for cleaning.
⑧Do not use pointed objects such as pens to press the setting buttons on the display panel. Doing so may
damage the setting buttons by piercing them.
⑨Do not put a piece of wire or other long thin object from pressure port. Doing so may damage the
internal diaphragm to cause malfunctioning.
⑩Do not use the product in a place where much steams and/or dust exist or the product may be subjected
to direct water or oil splash.

［Recommended measures against noise interference½
Surge absorbing circuit
It is recommended to use noise absorbing components (line filter, surge absorber, etc.) in the power supply
terminal of the PS30.

Error Messages
■ If the following error messages are displayed, follow the procedures in the table:
Error message
Problem
Overload current.
（Brinking of SW1 or SW2 indicates
excessive current on SW1 or SW2.）
Pressure detected when adjusting the zero point.
Examination by Nidec Copal Electronics is required.
Solution
Disconnect the power, then check the load condition.
Press the button and reset the display. Release the applied pressure
M
in the pressure port (opened to the atmosphere) and adjust the zero point again.
Telephone the nearest office or Sensor Department of Nidec
Copal Electronics Corp.
Pressure value exceeds 110% of the rating.
（This error examples
Check the applied pressure.
when the pressure more than 111kpa is applied to the 102R modele.）
Applied pressure is higher than the maximum value
of the pressure display range.
Applied pressure is higher than the maximum value
of the pressure display range.
Check the applied pressure.
Check the applied pressure.
（Note 1） error messages will be shown when non-display mode is selected.

（Note 2）
When the applied pressure exceeds 110％ of rated pressure, the display indicate flashing or −L− or −H− .
This displayed value is not accurate value, please use within the rated pressure range.
Functions
Non-display mode
●When you do not operate any buttons for about 10 seconds, the system will automatically select non-display mode
and the LED indicator section will go off. Pressing any key willcause the LED indicator section to come on back again.
（Note 1）
The decimal point shown in the figure on the right blinks during non-display mode.
（Note 2）
Switch outputs and switch LEDs are operable even during non-display mode.
（Note 3） error messages will appear during non-display mode.

●Two different digital filters (25ms and 250ms) are available.
The digital filters are useful when it is hard to take readings due to too great fluctuations in pressure.
（Note 1）
Any selected digital filter will be reflected on the pressure display and switch action.
※ For how to set the digital filter, see the description of the pressure setting mode.
