POINTS OF CAUTION
■NONINCENDIVE APPROVAL OPTION
• This equipment is suitable for use in Class I, Div. 2,
Groups A, B, C and D or Non-Hazardous Locations only.
• WARNING! Before You Remove the Unit from Its Base
Socket or Mount It, Turn Off the Power Supply and Input
Signal for Safety.
• WARNING! – Explosion Hazard –
Substitution of Components May Impair Suitability for
Class I, Div. 2.
• WARNING! – Explosion Hazard –
Do Not Disconnect Equipment Unless Power Has Been
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

■WARNING!
• To protect very delicate components contained inside
the unit against damage from static electricity, wear a
grounded wrist strap when handling them. If you do not
have one, touch both of your hands to a safely grounded
object or to a metal object.
• Ensure that the power supply and input signal are
switched off before you plug in or remove the unit.

• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -30 to +60°C
(-22 to +140°F) with relative humidity within 30 to 90%
RH in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with ca-
bles, etc.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 20 minutes is required for
satisfying complete performance described in the data

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Input range selector: Check that the switch is at the ap-
propriate position according to the input range model
suffix code.
3) Output range selectors: Check that the switches are at
the appropriate positions according to the output range
model suffix code.
4) Power input voltage: Check voltage across the terminal
13 – 14 with a multimeter.
5) Input: Check that the input voltage is within 0 – 100% of
full-scale.
6) Output: Check that the load resistance meets the de-
scribed specifications.
7) Status indicator LED: Check that it blinks in a regular
pattern.
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 turned open by 180 deg.
when there is no extra space between units.

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).
I/O RANGE MODIFICATION
Configurator software is used to change input over the de-
scribed range of the selected suffix code. For changing out of
this range (between S1 and S2), set the Input Range Selec-
tor on the side of unit before software adjustment.
For a current input, set the Selector to the same setting as
for S2 and use a receiving resistor.
Output ranges can be changed over the described range of
the selected suffix code with the Configurator Software.
For changing out of this range, set the Output Range Selec-
tors before software adjustment.

STATUS INDICATOR LED
The M2XF2 is provided with a status indicator LED which
blinks in different patterns indicating various status of its
CPU.
When it is functioning within normal parameters, the LED
blinks in a regular pattern of ON and OFF.
When the unit is in an abnormality, it blinks in particular
patterns repeating approximately in 1.3 seconds.
The following figure indicates typical patterns. A white
circle means that the light is OFF for 80 millisec., while a
black one means ON for 80 millisec.

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 “ZERO/
SPAN ADJUSTMENTS” explained earlier.
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
