POINTS OF CAUTION

■ POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and

conﬁrm its operational range as indicated below:

85 – 264V AC rating: 85 – 264V, 47 – 66 Hz, approx. 3 – 4VA

24V DC rating: Rating ±10%, approx. 2W

110V DC rating: 85 – 150V, approx. 2W

■ 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.

■ ENVIRONMENT

• Indoor use

• When heavy dust or metal particles are present in the air,

install the unit inside proper housing with sufﬁcient ven-

tilation.

• 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 0 to 50°C

(32 to 122°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 sup-

plied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data

sheet.

INSTALLATION

Detach the yellow clamps located at the top and bottom of

the unit to separate the body from the base socket.

■ DIN RAIL MOUNTING

Set the base socket so that its

DIN rail adaptor is at the bot-

tom. 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.

■ WALL MOUNTING

Refer to “EXTERNAL DI-

MENSIONS.”

TERMINAL CONNECTIONS

Connect the unit as in the diagram below or refer to the con-

Shape and size of the base socket

are slightly different with various

socket types.

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

7 – 14 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 de-

scribed speciﬁcations.

5) Split-range setting: Conﬁrm that the transmitter out-

puts are provided as intended.

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 accu-

racy described in the data sheet. When the output is out of

tolerance, recalibrate the unit using the PC Conﬁgurator

Software (moodel: MFS2CFG).

*Input shunt resistor attached for current input.
