actly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you
use this product, installation, connection and basic mainte-
nance procedures.
POINTS OF CAUTION
■ POWER INPUT RATINGS
• Power input ratings are specified by the model number
suffix code. Check the power input voltage for the unit on
the specification label.
AC power: rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC power: rating ±10%, approx. 2W
(85 – 150V for 110V rating)
■ GENERAL
• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ ENVIRONMENT
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +60°C
(23 to 140°F) for the transmitter and -10 to +55°C (14 to
131°F) for the probe, with relative humidity within 15 to
85% RH for the probe, 30 to 90% RH for the transmitter in
order to ensure adequate life span and operation.
• Do not cover the ventilation slits with cables, 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 sat-
isfying complete performance described in the data sheet.

• 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
screwdriver (–) and pull.

■ CURRENT PROBE
Mount the sensor so that the conductor passes near the
center of the sensor and at right angle to the sensor circle.
Otherwise, the position sensitivity may increase.
In order to separate the connection, pull out the sensor end
from the connector.
Use binding straps for fixing the position of the probe with
the attachments.

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 range selector switch is properly
set to match the input range. 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 suf-
ficient 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).
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.
