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:
AC power: Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC power: Rating ±10%, approx. 2W
■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.
•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 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.

Shape and size of the base socket
are slightly different with various
socket types.
■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

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 – 8 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 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 the input signals which should lead the
calculated result as 0%, and adjust output to 0%.
2) SPAM: Apply the input signals which should lead the
calculated result as 100%, and adjust output to 100%.
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)
Output, Input 1, Input 2: 0 – 100%
Note: Be aware that a input signal less than 0 % is calculated
as a minus signal.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply the input
signals which should lead the calculated results as 0%, 25%,
50%, 75% and 100%. 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, rec-
alibrate the unit according to the “ADJUSTMENT PROCE-
DURE” explained earlier.
LIGHTNING SURGE PROTECTION
