■ MODEL NO.
Check that model No. described on specification label is
exactly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you
use this product, installation, connection and basic maintenance procedures.
POINTS OF CAUTION
■ CONFORMITY WITH CE DIRECTIVES
• This equipment is suitable for use in a Pollution Degree 2
environment and in Installation Category II, with the maximum operating voltage 300V.
Basic insulation is maintained between the strain gauge
input or excitation or contact input and output. 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.
• Insert a noise filter for the power source connected to the
unit. Densei-Lambda Noise Filter Model MZS-1206-33 or
equivalent is recommended.
• 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.
■ POWER INPUT
• Operational voltage range, frequency and power consumption: Check the power rating for the unit on the specification
label.
Rating 100 – 240V AC: 85 – 264V, 47 – 66 Hz, approx. 10VA
Rating 24V DC: 24V ±10%, approx. 7W
Rating 110V DC: 85 – 150V, approx. 7W
• Power fuse: A power fuse of the rating as shown below is
incorporated for safety. However, DO NOT replace it by the
user.
T 0.5A 250V
■ UNPLUGGING THE UNIT
• Before you remove the unit from its base socket or mount it,
turn off the power supply and input signal for safety.
MXLC
■ ENVIRONMENT
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +55°C (23
to 131°F) with relative humidity within 30 to 90% RH in order
to ensure adequate life span and operation.
■ WIRING
• Do not install cables (power supply, input and output) 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.

■ SENSOR ADJUSTMENTS USING AN ACTUAL LOAD
1. Program Mode
Set ITEM 01 – DATA 2 to turn the unit into Program
Mode.
2. Excitation Voltage
Choose ITEM 05. Press Data UP or DOWN key until the
data display shows the desired excitation voltage. When
the value calculated by [Excitation / Resistance] exceeds
30mA, set a voltage value to fit with 30mA limit.
[E.G. 1]
Max. excitation voltage
10V
Strain gauge resistance
120Ω
If you choose 10V as the excitation:
10V / 120Ω = 83.3mA ––> out of allowable range
Then you will choose 3.6V or less as calculated by the
equation below:
30mA × 120Ω = 3.6V
3. 0% Input Voltage
Choose ITEM 07. With no load applied to the sensor, press
DATA UP or DOWN key until the display value is stabilized (while the computation circuit of the unit conducts
averaging process).
DATA display shows the approximate offset voltage.
Display Value = Sensor Voltage × Internal Coefficient*
4. 100% Input Voltage
Choose ITEM 08. With an actual known load, press DATA
UP or DOWN key until the display value is stabilized
(while the computation circuit of the unit conducts averaging process).
Data display shows the sensor's sensitivity span.
5. Monitor Mode
Set ITEM 01 – DATA 1 to turn the unit into Monitor Mode.
6. PV Indication
Press ITEM UP or DOWN key until ITEM display indicates "P".
If necessary, go to Display Range Scaling, Moving Average,
and other adjustments.
Set the unit to Monitor Mode with ITEM P displayed other
than for programming.
*If 100% load is not available, use the load ratio setting.
With 10% load, set ITEM 09 – DATA 10.0 before adjustments.

4. Turn the unit into Monitor Mode.
5. Set to ITEM P.
■ TARE ADJUSTMENT
1. Turn the unit into Program Mode.
2. Contact Input Function
Choose ITEM 18 – DATA 0.
3. Turn the unit into Monitor Mode.
(ITEM 18 is set to DATA 0 as default. No need of
conducting 1 through 3.)
4. Set to ITEM P.
5. Close across the contact input terminals (Di).
By the abovementioned procedure, the tare value is stored in
ITEM 10, the PV display shows the value set by 0% Scaling
Value, and the transmitter outputs the value set by 0%
Output.
The abovementioned procedure is applicable to modifications
from default setting.

CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Strain gauge: Maximum allowable current supplied to the
strain gauge is 30mA. Check the resistance of the sensor.
4) Input: Check voltage across the terminal 10 (+) – 11 (–)
with a multimeter. The voltage value at the maximum
load must equal [Excitation × Strain Gauge Sensitivity].
5) Output: Check that the load resistance meets the described specifications.
MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
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. When the output is out of
tolerance, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
