• 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:
24V DC rating: 24V ±10%, ≤ 6W
■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.

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. The destination changes depending on how
long the button is held down. Used to return from each setting mode to measuring mode (press and
hold for 2 sec. or more).
Up button Used to shift through setting parameters and to increase or select setting value.
Down button Used to shift through setting parameters and to decrease or select setting value.
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 at setting changeable state.
Used to release latching alarm in measuring mode (press and hold for 2 sec. or more).
Configurator Jack Used to configure with M1EA configurator software (model: M1EACFG). At the same time, set the
lockout setting of the unit to ‘lock’.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
19 – 20 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
full-scale.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 250 V AC/ 120
VA or 125 V DC/30 W at the maximum.
For maximum relay life with inductive load, external pro-
tection is recommended.

MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes.
• H Setpoint
Increase the input signal from a value lower than the set-
point and check that the relay trips at the setting value.
• L Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the relay trips at the setting val-
ue.
• Input Value
Apply 0%, 25%, 50%, 75% and 100% input signal. Per-
form input fine adjustment when input value is out of
accuracy on the display.
Refer to the operating manual (EM-6031-B), when adjust-
ing with front buttons. Refer to the M1EACFG users man-
ual (EM-5994), when adjusting with M1EA Configurator
Software (model: M1EACFG). And then follow the proce-
dure shown below.
• INPUT FINE ADJUSTMENT
1) Set the input signal to 0 %, and adjust the input display
to 0 % by [80] Input Zero fine adjust.
2) Set the input signal to 100 %, and adjust the input dis-
play to 100 % by [81] 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).
