Switched Off or The Area is Known To Be Non-Hazardous.
• The equipment was evaluated for use in the ambient tem-
perature and relative humidity as mentioned in ‘ENVI-
RONMENT’ section.
• The input and output wiring must be in accordance with
Class I, Div. 2 wiring methods and in accordance with the
authority having jurisdiction for use in these hazardous
locations.
■CONFORMITY WITH EU DIRECTIVES OR UL
• This equipment is suitable for Pollution Degree 2 and In-
stallation Category II (transient voltage 2500V). Rein-
forced insulation (signal input or output to power input:

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
4) Input: Check that the input voltage is within 0 – 100% of
full-scale.
5) Output: Check that the load resistance meets the de-
scribed specifications.
6) Status indicator LED: Check that it blinks in the normal
patterns.
ZERO/SPAN ADJUSTMENTS
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
For matching the signal to a receiving instrument or in case
of regular calibration, fine zero and span adjustments can
be done to ±5% by pressing UP/DOWN switches enabled
with the zero/span selector switch. Calibrated values are
stored in the non-volatile memory, which will not be lost
even when you turn off power supply to the unit.
Zero and span are respectively set to 0% and 100% at the
factory.
UP/DOWN Switches
The front cover cannot be opened to 180 deg.
when flush with neighboring units.

ZERO: UP/DOWN switches usable for zero adjustment.
OFF: UP/DOWN switches unavailable.
SPAN: UP/DOWN switches usable for span adjustment.
UP/DOWN Switches
UP: Pressing UP increases adjusted values.
DOWN: Pressing DOWN decreases adjusted values.
■HOW TO CALIBRATE THE ZERO
Slide the Zero/Span Selector to the bottom position and
press UP or DOWN switch. Incrementing speed will be
doubled when you keep pressing a switch.
■HOW TO CALIBRATE THE SPAN
Slide the Zero/Span Selector to the top position and press
UP or DOWN switch. Incrementing speed will be doubled
when you keep pressing a switch.
■HOW TO RESET
After you calibrated manually with these switches, you
can reset them to its ex-factory state by pressing both UP/
DOWN switches at once.
■ADJUSTMENT PROCEDURE
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 20 minutes.
1) ZERO: Apply 0% input. Slide the Zero/Span Selector to
the bottom position. Press UP or DOWN switch and ad-
just output to 0%.
2) SPAN: Apply 100% input. Slide the Zero/Span Selector
to the top position. Press UP or DOWN switch and adjust
output to 100%.
3) Check ZERO adjustment again with 0% input.
4) The ZERO and SPAN adjustments are processed in a dig-
ital processor, and therefore they do not interact. Howev-
er, if ZERO value is changed, repeat the above procedure
1) – 3).

ADJUSTING DETECTING LEVEL (voltage pulse, two-wire current pulse only)
Appropriate detecting level is determined according to the flow chart below.
START
Confirm the Sensitivity Scale in the table
below.
Assign the value in the following equation.
Detecting Level (V) =
DC Offset (V)*1× Sensitivity Scale
Set DIP SW to the DC coupling and adjust
the detecting level to the value calculated
above.
Set to 4V when the calculation result is
higher than 4V, set to -2V when it is lower
than -2V.
Adjust the detecting level
appropriate for the sensor
excitation voltage.
Adjust the detecting level
to 0V appropriate for
RS-422 line driver pulse
input.
Set DIP SW to the capacitor
coupling and adjust the
detecting level to 0V.

■DETECTING LEVEL
When the parameters have been set with DIP switches and
the PC Configurator Software (model: JXCON), a specific
sensitivity scale is applied according to the pulse amplitude
setting. The scaled input voltage is then compared to the
preset detecting level (-2.00 to +4.00V).
With DC coupling, the scaled maximum voltage must be
higher than the detecting level and the minimum voltage
must be lower than that so that the pulse state is accurately
detected. (Refer to the instruction manual for detailed in-
formation about adjusting the detecting level.)

MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 20 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the “ADJUST-
MENT PROCEDURE” explained earlier.
