POINTS OF CAUTION
■ POWER INPUT RATING & OPERATIONAL RANGE
• Check the power rating for the unit on the specification label.
85 – 132V AC rating: 85 – 132V, 47 – 66 Hz, approx. 6VA
12, 24, and 48V DC ratings: Rating ±10%, approx. 3.3W
110V DC rating: 85 – 150V DC, approx. 3.3W
■ 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 ventila-
tion.
• 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 +60°C (23
to 140°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 the unit's cables together with cables where
high noise levels are present. Do not install them in the same
duct.
■ AND ....
• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.
COMPONENT IDENTIFICATION
■ HOW TO OPEN THE FRONT COVER:
Position your finger on the hook at the top of front cover and
pull.
INSTALLATION
Detach the yellow clamps located at the top and bottom of the
unit for separating 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

CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
–8with 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.
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 "ANALOG
OUTPUT ADJUSTMENT" procedure.

■ PULSE AMPLITUDE (rotary switch) (*) Factory setting
For voltage pulse input, select the pulse amplitude (V p-p)
among the switch positions 0 through 6. For open collector
or two-wire current pulse input, set the switch to 7. DO
NOT SET to 8 or 9. The power supply to the unit must be
turned off when changing the setting.
■ DIP SWITCH SETTING (*) Factory setting
SW6 is not used. The power supply to the unit must be turned
off when changing the setting.

■ DETECTING LEVEL
A specific sensitivity scale is applied according to the pulse
amplitude setting. The scaled input voltage is then com-
pared to the preset detecting level.
The scaled H level voltage must be higher than the detect-
ing level so that the pulse state is accurately detected.

•How to Change the Detecting Level
A pulse generator which can simulate the selected input type
and waveforms with appropriate amplitude is required.
1) Set the rotary switch and the DIP switch to an appropriate
input type and pulse amplitude.
2) Connect the positive probe of the pulse generator to the
terminal 5, the negative probe to the terminal 6 of the base
socket.
3) Set the pulse generator output to 1 kHz with the duty ratio
50%, and apply the signal to the transmitter.
4) Connect the Programming Unit to the modular jack and
execute [GROUP 01] [ITEM 06] to show the input duty
ratio.
5) Press [ENTER] key multiple times to adjust the detecting
level until the display shows 50.00 ±0.1%. This adjust-
ment affects the transmitter’s accuracy. Be sure to set the
duty ratio within 0.1% allowances.
6) Confirm that the input monitor LED (PL1) is ON (it should
actually be flashing in 1 kHz). If the LED does not turn on,
the detecting level may be out of the pulse amplitude
range. Change the detecting level again.

■ SENSOR EXCITATION ADJUSTMENT
You can change the sensor excitation voltage with the sensor
excitation adj. located behind the front cover. If you need to
change it, check that the required current is within the
specification.
•How to Change the Excitation
A voltmeter and ammeter of class 0.5 or better accuracy are
required.
1) Connect the voltmeter across the terminals 4 – 6.
2) Connect the ammeter to terminal 4.
3) Turn the potentiometer until the meter shows the desired
value.
Check that the current value indicated on the ammeter is
within the allowable limit. If the value is greater than the
limit, lower the voltage value or connect a separate power
source. Otherwise, the transmitter may fail.
■ ANALOG OUTPUT ADJUSTMENT
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibra-
tion.
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%.
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 procedure
1) – 3).
