basic maintenance procedures.
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:
15V DC ±2%, approx. 35mA with 20mA output
•Whenthereisspikenoisesinthepower,makealterwith
an appropriate capacitor and inductor to cut it off.
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60°C(32
to140°F)withrelativehumiditywithin10to95%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.
•Mounting multiple isolator modules on single printed
wiring board could cause beat. In such case, use the way
shown as below to make the power supply oscillation fre-
quency of each module to a same one for prevention.

INSTALLING THE MODULE
Whenitisinstalledontheprintedwiringboard,landdiam-
eterø1.5andthrough-holeø0.9arerecommended.
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.

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 pins.
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0%inputandadjustoutputto0%.
