please contact M-System's Sales Office or representatives.
■ PACKAGE INCLUDES:
Signal conditioner (body + CJC sensor)................. (1)
■ MODEL NO.
Check that model No. described on the specification label is
exactly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you
use this product, including installation, connection and basic
maintenance procedures.
When you need to change software settings, please refer to
the Operation Manual for Model PU-2❑(EM-9255), Section
A.
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.
24V DC ±10%, approx. 60mA with Voltage Output 1
approx. 90mA with Current Output 1
• Power fuse: A power fuse of the rating as shown below is
incorporated for safety. However, DO NOT replace it by the
user.
F 0.5A 125V
■ GENERAL SAFETY PRECAUTION
• 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 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 +55°C (23
to131°F)with relative humidity within 30to 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 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
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.

TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connection diagram label on the unit side. Attach the CJC sensor together
with input wiring to the input screw terminals. Be sure that the serial number of CJC sensor (CJM) is the same as that of the
module, as the sensor is not interchangeable.

CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BX❑). For the DC power source, be sure that
the ripple level is within 10% p-p.
3) Input: Check that the input voltage is within 0 – 100% of
full-scale.
If the thermocouple or its extention wires are broken, the
output goes over 100% (below 0% with downscale protec-
tion) due to burnout protection 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 calibra-
tion, 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-2❑). 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) maintain-
ing electrical connection to the rear connector.
Refer to the Operation Manual for Model PU-2❑for explana-
tions 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.
■ 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 (de-
fault: 0%) at ITEM 19 until the output signal is calibrated
to actual 0%.
3) Apply simulated 100% input. Increase/decrease value
(default: 100%) at ITEM 20 until the output signal is
calibrated 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 procedure
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.
