SCALE
*Limited to ≤70V for CE conformance or UL approval.
**Input frequency ≤50 kHz
A specific sensitivity scale is applied according to the pulse
amplitude by setting up the DIP switch and PC Configurator
Software (model: JXCON). The scaled input voltage is then
compared to the detecting level at -2.00 through +4.00V.
With DC coupling, the scaled maximum input voltage level
voltage must be higher than and the scaled minimum input
voltage level must be lower than the detecting level so that
the pulse state is accurately detected.

■ WALL MOUNTING
Refer to ‘EXTERNAL DIMENSIONS.’
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the con-
nection diagram on the side of the unit.
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
13 – 14 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 flashes in the nor-
mal 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.
■ FRONT VIEW (with cover open)
Zero/Span Selector
ZERO:UP/DOWN switches usable for zero adjust-
ment.
OFF: UP/DOWN switches unavailable.
SPAN: UP/DOWN switches usable for span adjust-
ment.
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
adjust output to 0%.
2) SPAN: Apply 100% input Slide the Zero/Span Selector
to the top position. Press UP or DOWN switch and ad-
just output to 100%.
3) Check ZERO adjustment again with 0% input.
4) The ZERO and SPAN adjustments are processed in
UP/DOWN Switches
The front cover cannot be opened to 180 deg.
when flush with neighboring units.

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 Table 1
below.
Assign the value in the following equation.
Detecting Level (V)*1=
DC Offset (V)*2×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.
Set DIP SW to the capacitor
coupling and adjust the
detecting level to 0V.
DC coupled input sensing? No
Yes
*1.
*2. Rounded off to two decimal places. Divide a current input (mA) by 10 and convert it into voltage (V).
e.g. Offset = 10mA --> 10mA x 1/10 = 1V
Table 1
A specific sensitivity scale is applied according to the pulse
amplitude by setting up the DIP switch and PC Configura-
tion Software. The scaled input voltage is then compared to
the detecting level at -2.00 through +4.00V.
With DC coupling, the scaled maximum input voltage level
voltage must be higher than and the scaled minimum input
voltage level must be lower than the detecting level so that
the pulse state is accurately detected.
PULSE AMPLITUDE SENSITIVITY SCALE
50 – 100V p-p 1/20
25 – 50V p-p 1/10
10 – 25V p-p 1/5
5 – 10V p-p 1/2
1 – 5V p-p 1
0.5 – 1V p-p 5
0.1 – 0.5V p-p 10

STATUS INDICATOR LED
The M2XPA3 is provided with a status indicator LED which
flashes in different patterns indicating various status of its
CPU. Typical patterns are as shown below.
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.

However, if ZERO value is changed, repeat the above
procedure 1) – 3).
CHANGING I/O TYPE & RANGE
Input type and range, and output type and range can be
