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:
24V DC rating: 24V ±10%,
approx. 60mA with voltage output 1
approx. 90mA with current output 1
■GENERAL PRECAUTIONS
• Before you remove the unit 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.
• Be sure to put the terminal cover on while the power is
supplied.
■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.

WIRING INSTRUCTIONS
■SCREW TERMINAL
Torque: 0.8 N·m
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BXx). For the DC power source, be sure that
the ripple level is within 10% p-p.
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, 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 for the Output
2 can be done with the potentiometers on top of the unit
which are accessible using Extender Card (model: 10EC)
maintaining electrical connection to the rear connector.
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 1
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).
■HOW TO CALIBRATE THE OUTPUT 2
Use Extender Card (model: 10EC) to access the Output 2
Adjustments on top of the unit.
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.

portionally to an average of N numbers of sampled data. When a
new input is sampled after another H seconds, it gives up the oldest
sample and calculates a new average including the latest sample
and outputs proportionally.
