BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■ PACKAGE INCLUDES:
Signal conditioner (body + base socket)....................... (1)
■ MODEL NO.
Confirm that the model number described on the product is
exactly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
W2DYH2
•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.
•Be sure that the ventilation slits are not covered with cables, etc.
■ 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.
COMPONENT IDENTIFICATION
POINTS OF CAUTION
Body
■ CONFORMITY WITH EC DIRECTIVES
•This equipment is suitable for use in a Pollution Degree 2
environment and in Installation Category II. Reinforced
insulation (signal input or outputs to power input: 300V)
and basic insulation (signal input to output 1 to output 2:
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 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 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, approx. 5 – 8VA
24V DC rating: 24V ±10%, approx. 4W
11 – 27V DC rating: 11 – 27V, approx. 4W
110V DC rating: 85 – 150V, approx. 4W
■ 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.

INSTALLATION
Loosen the fixing screw at the front of the unit in order to
separate the body from the base socket.
■ DIN RAIL MOUNTING
Set the base socket so that
its DIN rail adaptor is at
the bottom. Position the
upper hook at the rear side
of base socket on the DIN
rail and push in the lower.
When removing the socket,
push down the DIN rail
adaptor utilizing a minus
screwdriver and pull.

TERMINAL CONNECTIONS
ADJUSTMENT PROCEDURE
Connect the unit as in the diagram below or refer to the connection diagram on the side of the unit.
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.

■ HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above procedure 1) – 3).
5) Go through the same procedure for the Output 2.
MAINTENANCE
Regular calibration procedure is explained below:
+ 4
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
10 – 11 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the described specifications.
For HART communication, the resistance must be 225 - 600 Ω.
■ 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.
