POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• 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:
300V) and basic insulation (signal input to output: 300V)
are maintained. Prior to installation, check that the insu-
lation class of this unit satisfies the system requirements.
• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures* to ensure the CE con-
formity.
* For example, installation of noise filters and clamp fil-
ters for the power source, input and output connected
to the unit, etc.
• Install lightning surge protectors for those wires connect-
ed to remote locations.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz,
≤ 4.5VA at 100V AC
≤ 6.5VA at 200V AC
≤ 8.5VA at 264V AC
24V DC rating: 24V ±10%, ≤ 2.3W
110V DC rating: 85 – 150V, ≤ 2.3W
■GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ENVIRONMENT
• 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 -5 to +55°C
(23 to 131°F) with relative humidity within 10 to 85% 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 10 minutes is required for
satisfying complete performance described in the data
sheet.
• With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to
endure it without breakdown, however, it may shorten ap-
propriate life duration.
• The edge of the display may be hidden by the frame and
invisible depending on the view angle.

COMPONENT FUNCTION
Display Indicates present values, setting values and abnormal information.
Two types of present values are displayed respectively at the upper and lower parts according to setting.
Mode button Shifts from Measuring mode to each setting mode.
The destination changes depending on how long the button is held down.
Pressing Mode button for ≥ 2 seconds returns to Measuring mode from each setting mode..
Set button Shifts the setting value of each setting parameter item to a setting changeable state.
When at setting changeable state, used to move through the digits of setting value for input/output scal-
ing and to enter (save) the setting value.
Up button Shifts through setting parameter items and to increase or select the setting value.
Down button Shifts through setting parameter items and to decrease or select the setting value.
Configurator Jack Used to perform configuration with M2E configurator software (model: M2ECFG).
When using the software, set the Lockout setting of the unit to ‘Lock’.
DIP SWITCH
The internal DIP switch for output setting is required to select output types before setting a precise output range using front
buttons or setting with a PC.
Refer to the operating manual (EM-5133-B) for the operation with front buttons. Refer to the users manual (EM-5147) of
M2E Configurator Software (model: M2ECFG) for setting with PC.

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 signal is within 0 – 100% of
the full-scale.
5) Output: Check that the load resistance meets the de-
scribed specifications.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Without linearization, warm up the unit for at least 10
minutes. Apply 0%, 25%, 50%, 75% and 100% input signal.
Check that the output signal for the respective input sig-
nal remains within accuracy described in the data sheet. If
the output signal is out of accuracy, when the input display
value is out of accuracy, perform the input fine adjustment.
When the input display value is correct but the output is
out of accuracy, perform the output fine adjustment. Refer
to the operating manual (EM-5133-B), when adjusting with
front buttons. Refer to the M2ECFG users manual (EM-
5147), when adjusting with M2E Configurator Software
(model: M2ECFG). And then follow the procedure shown
below.
• INPUT FINE ADJUSTMENT
1) Set the input signal to 0%, and adjust the input display to
0% by [69] Input Zero fine adjust.
2) Set the input signal to 100%, and adjust the input display
to 100% by [70] Input Span fine adjust.
3) Again set the simulated input to 0%, confirm the input
display.
4) If input display is shifted, repeat the procedure from 1) to
3).
• OUTPUT FINE ADJUSTMENT
1) Set the simulated input to 0%, and adjust the output sig-
nal to 0% by [71] Output Zero fine adjust.
2) Set the simulated input to 100%, and adjust the output
signal to 100% by [72] Output Span fine adjust.
3) Again set the simulated input to 0%, confirm the output
signal.
4) If output signal is shifted, repeat the procedure from 1) to
3).
