tion class of this unit satisfies the system requirements.
• 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. 3 – 5VA
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 MOUNTINGSet 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 MOUNTINGRefer to “EXTERNAL DI-
MENSIONS.”

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
13 – 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.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
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 SIGNALUse 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 the input signals which should lead the
calculated result as 0%, and adjust output to 0%.
2) SPAN: [K1+ K2≥ 1] Apply the input signals which should
lead the calculated result as 100%, and adjust output to
100%.
[K1+ K2< 1] Apply the input signals which should lead
the calculated result as [100 ×(K1+ K2)]%, and adjust
output to [100 ×(K1+ K2)]%.
3) Check ZERO adjustment again.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).
EQUATION
Output = K1×Input 1 + K2×Input 2
K1, K2: 0.10 to 2.00 specified when ordering
(0.40 ≤ K1+ K2)
Input 1, Input 2: 0 to 120%
Forcibly limited to 0% and 120% respectively when
the signal is out of range.
MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATIONWarm up the unit for at least 10 minutes.
[K1+ K2≥ 1] Apply the input signals which should lead the
calculated result as 0%, 25%, 50%, 75% and 100%. Check
that the output signal for the respective input signal re-
mains within accuracy described in the data sheet.
[K1+ K2< 1] Apply the input signals which should lead the
calculated result as 0%, [25 ×(K1+ K2)]%, [50 ×(K1+ K2)]%,
[75 ×(K1+ K2)]% and [100 ×(K1+ K2)]%. 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 ac-
cording to the “ADJUSTMENT PROCEDURE” explained
earlier.
