POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
•This equipment is suitable for Pollution Degree 2 and In-
stallation Category II. Reinforced insulation (signal in-
put 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 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 conform-
ity.
•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 – 120V AC rating: 85 – 132V, 47-66 Hz, ≤ 5VA
200 – 240V AC rating: 170 – 264V, 47-66 Hz, ≤ 7VA
■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 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 en-
dure 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 at up-
per 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 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 “PROGRAMMING” for the operation with front buttons. Refer to the users manual (EM-5147) of M2E Configurator
Software (model: M2ECFG) for setting with PC.

■OPERATION IN EACH SETTING MODE
• Basic operation
Mode Button: In measuring mode, holding down Mode button for ≥ 2 seconds, ≥ 4 seconds, ≥ 6 seconds or ≥ 8 seconds
enables to move on to each setting mode. Holding down Mode button for ≥ 2 seconds at each setting item
display enables to return to measuring mode.
Holding down Mode button for ≥ 2 seconds while changing settings (‘(Setting)’ is displayed next to ‘DATA’)
enables to discard setting value in changing, and to return to the state before change settings (‘(Setting)’
next to ‘DATA’) is off).
Set Button: Pressing Set button at each setting parameter enables to blink setting value and changing settings is
ready (‘(Setting)’ is displayed next to ‘DATA’). Pressing Set button while changing settings enables to
enter (save) setting value and change from blinking to on.
Up Button: Press Up button to move through setting parameters. Selecting setting value while changing settings,
increasing a setting value to set value. Keeping pressing Up button enables to increase the value
continuously.
Down Button: Press Down button to move through setting parameters. Selecting setting value while changing settings,
decreasing a setting value to set value. Keeping pressing Down button enables to decrease the value
continuously.
• Operation of input setting parameter
[06] Angle offset is set by teach.
The present input value is displayed by pressing set button. With input value desired as 0% is entered, pressing set button
again enables to fix the setting.
[07] Angle span sets width used.
Angle for 0% = [06], angle for 100% = [06] + [07]
• Input/output scaling setting parameter
For input/output scaling setting parameter, set values digit by digit. Pressing Set button enables to move blinking digit.
Adjust blinking digit to set numerical value with Up and Down button. Blinking digit moves from most significant digit with
pressing Set button. At least significant digit, pressing Set button again enables to turn on and determine the setting value.
During setting, press and hold Mode button for ≥ 2 seconds to discard the setting value.
