When the device is located at the end of a transmission line via twisted-pair cable,
(when there is no cross-wiring), close across the terminal T2 –T3 with the attached
jumper pin (or with a leadwire).
When the device is not at the end, remove the jumper pin.
Remark 1: This device is not designed to cancel noise included in the input signals.
Be careful to eliminate such noise by using shielded cables.
Remark 2: Be sure to maintain the same potential at all the common negative
terminals for DC input.

Circuit
When the device is located at the end of a transmission line via twisted-pair cable,
(when there is no cross-wiring), close across the terminal T2 –T3 with the attached
jumper pin (or with a leadwire).
When the device is not at the end, remove the jumper pin.
Remark 1: This device is not designed to cancel noise included in the input signals.
Be careful to eliminate such noise by using shielded cables.
Remark 2: Be sure to maintain the same potential at all the common negative
terminals for DC input.

TERMINAL CONNECTIONS
Connect the module referring to the connection diagram.
Attach the CJC sensor together with input wiring to the input screw terminals. The sensor is calibrated for each particular
module and not interchangeable with another. Check the serial numbers of the module and sensor.

CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input: Chec
k supply voltage.
3) Input: Check that the input is within 0 – 100% of fullscale.
4) DIP SW setting:
Check that all switches are set correct-
ly.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.

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 accuracy described in the data sheet. When the output is out of
tolerance, please contact M-System’s Sales Office or representatives.
