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. 3 VA
DC power: Rating ±10%, approx. 2 W
■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.

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 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.

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.
(With 20°C or 68°F, approx. 220 mV with Pt 100, approx.
110 mV with Pt 50 Ω.)
If RTD wires are broken, the output goes over 100% (be-
low 0% with downscale protection) due to burnout protec-
tion function. Check leadwires in such a case.
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, unless you need to match the signal to a receiving
instrument or conduct regular calibration.
Zero and span are adjusted with using the Programming
Unit (model: PU-2x). Also, fine adjustments can be done
with the potentiometers behind the front cover.
Refer to the Operation Manual for Model PU-2x for expla-
nations how to use the programmer.
■WARNING ON USE OF THE PROGRAMMING UNIT
•Be sure to disconnect the Programming Unit before you
turn on/off power supply to the unit.
•The output signal is held when the Programming Unit is
connected. You need to disconnect when confirming cur-
rent output values.
■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.
• Fine Output Calibration
Using the Programming Unit (ITEM 19, 20)
ITEM 19 is for Zero, and ITEM 20 is for Span.
1) Turn the unit into Program mode (ITEM 01).
2) Apply simulated 0% input. Increase/decrease values
(default: 0%) at ITEM 19 until the output signal is cali-
brated to actual 0%.
3) Apply simulated 100% input. Increase/decrease value
(default: 100%) at ITEM 20 until the output signal is cali-
brated to actual 100%.
4) Apply simulated 0% input again and check 0% output.
5) When 0% value is changed, repeat the above procedure
2) - 4).
The 0% value may be shifted when the output span is
greater than the input span (gain >1).
• Fine Output Calibration via the Front Potentiometers
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.
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
M-System to choose appropriate models.
