POINTS OF CAUTION

■ CONFORMITY WITH EU DIRECTIVES

•This equipment is suitable for Pollution Degree 2 and In­stallation Category II. Reinforced 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 insulation 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 con­form to CE requirements. Failure to observe these re­quirements may invalidate the CE conformance.

•The actual installation environments such as panel con­figurations, connected devices, connected wires, may af­fect 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 conform­ity.

•Install lightning surge protectors for those wires connect­ed 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 the 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.

■ 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 sup­plied, 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 ap­propriate 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 at

upper and lower are displayed by setting.

Mode button Used to shift from measuring mode to each setting mode. Destination to shift is changed by the time

pressing and holding the button. Used to return from each setting mode to measuring mode. (press
and hold for 2 sec. or more)

Set button Used to change setting value of setting parameter. When at setting changeable state, used to enter

(save) the setting value. Used to move on through digits of setting value for input/output scaling at
setting changeable state,

Up button Used to shift through setting parameter, and to increase or select setting value.

Down button Used to shift through setting parameter, and to decrease or select setting value.

Configurator Jack Used to configure with M2E configurator software (model: M2ECFG). At the same time, set the lock-

out 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 con­nected 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 de­scribed 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 signal 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 this manual, 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
signal 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).
