Switched Off or The Area is Known To Be Non-Hazardous.
• The equipment was evaluated for use in the ambient tem-
perature and relative humidity as mentioned in ‘ENVI-
RONMENT’ section.
•The input and output wiring must be in accordance with
Class I, Div. 2 wiring methods and in accordance with the
authority having jurisdiction for use in these hazardous
locations.
■ CONFORMITY WITH EC DIRECTIVES OR UL
• This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II, with the
maximum operating voltage of 300V.
Basic insulation is maintained between signal input, out-
put 1 and output 2. Prior to installation, check that the
insulation class of this unit satisfies the system require-
ments.
•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/UL requirements. Failure to observe these re-
quirements may invalidate the CE/UL conformance.
■ 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 (90 – 264V for UL),
47 – 66 Hz, approx. 4 – 6VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W
110V DC rating: 85 – 150V (110V ±10% for UL), approx. 3W
■ 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 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 -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 ca-
bles, 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 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.
COMPONENT IDENTIFICATION
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.
■ WALL MOUNTING
Refer to “EXTERNAL DI-
MENSIONS.”

M-SYSTEM WARRANTY
M-System warrants such new M-System product which it manufactures to be free from defects in materials and workmanship during the 36-month period following the date that such
product was originally purchased if such product has been used under normal operating conditions and properly maintained, M-System’s sole liability, and purchaser’s exclusive
remedies, under this warranty are, at M-System’s option, the repair, replacement or refund of the purchase price of any M-System product which is defective under the terms of this
warranty. To submit a claim under this warranty, the purchaser must return, at its expense, the defective M-System product to the below address together with a copy of its original

TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the con-
nection diagram on the side of the unit.
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
10 – 11 with a multimeter.
3) Input: Check voltage across the terminal 2 (+) – 4 (–)
with a voltmeter to show 0V at 0% potentiometer input
and the same voltage as that across 1 (+) – 4 (–) at 100%
input.
4) Output: Check that the load resistance meets the de-
scribed specifications.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory with the total resist-
ance input, therefore you do not need any calibration if you
use the potentiometer’s total resistance.
When you do not use the total resistance or in case of regu-
lar calibration, adjust the output as explained in the fol-
lowing.
■ 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 proce-
dure 1) – 3).
5) Go through the same procedure for the Output 2.
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 according to the “ADJUST-
MENT PROCEDURE” explained earlier.
