Error Messages

●You can select switch working mode from the options shown in the table below.

（Note 1）In the Separate Mode, SW1 and SW2 work separately.

（Note 2）In the Window Comparator Mode, the minimum value for SW1 and SW2 corresponds to Setting 1 and the maximum value to Setting 2.

※For how to set the switch output, see the description of the initial setting 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）No error messages will appear during non-display mode.

※For how to select non-display mode, see the description of the initial setting 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.

■ If the following error messages are displayed, follow the procedures in the table:

（Note 1）No error messages will be shown when non-display mode is selected.

（Note 2）When the applied pressure exceeds 110％ of rated pressure, the display indicateflashingor −L− or −H− .

    This displayed value is not accurate value, please use within the rated pressure range.

●You can select a conversion factor from the options shown in the table on the right.

（Note 1）Slashed box: No factors options are available due to inappropriate resolution

     and the number of digits for display.

※For how to set the conversion factor, see the description of the initial setting mode.

Error message

Problem

Solution

Overload current.（Brinking of SW1 or SW2 indicates

excessive current on SW1 or SW2.）

Applied pressure is higher than the maximum value

of the pressure display range.

Pressure detected when adjusting the zero point.

Examination by Nidec Copal Electronics is required.

Pressure value exceeds 110% of the rating.（This error examples

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.

Check the applied pressure.

Check the applied pressure.

Check the applied pressure.

Press the   button and reset the    display. Release the applied pressure

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.

Disconnect the power, then check the load condition.
