WIRING INSTRUCTIONS
■ SCREW TERMINAL
Torque: 0.8 N·m
■ SOLDERLESS TERMINAL
Refer to the drawing below for recommended ring tongue
terminal size. Spade tongue type is also applicable.
Applicable wire size: 0.25 to 1.65 mm
Recommended manufacturer: Japan Solderless Terminal
MFG.Co.Ltd, Nichifu Co.,ltd
3.3 (.13) max
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of
the full-scale.
If the thermocouple or its extension wires are broken, the
output goes over 100% (below 0% with downscale protec-
tion) due to the burnout function. Confirm the burnout
error and check leadwires in such a case.
5) Output: Check that the load resistance meets the de-
scribed specifications.

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. If the output signal is out
of accuracy, when the input display value is out of accuracy,
perform the input fine adjustment. When the input display
value is correct but the output is out of accuracy, perform
the output fine adjustment. Refer to the operating manual
(EM-5145-B), when adjusting with front buttons. Refer to
the M2ECFG users manual (EM-5147), when adjusting
with M2E Configurator Software (model: M2ECFG). And
then follow the procedure shown below.
• INPUT FINE ADJUSTMENT
1) Set the input signal to 0%, and adjust the input display to
0% by [69] Input Zero fine adjust.
2) Set the input signal to 100%, and adjust the input display
to 100% by [70] Input Span fine adjust.
3) Again set the simulated input to 0%, confirm the input
display.
4) If input display is shifted, repeat the procedure from 1) to
3).
• OUTPUT FINE ADJUSTMENT
1) Set the simulated input to 0%, and adjust the output sig-
nal to 0% by [71] Output Zero fine adjust.
2) Set the simulated input to 100%, and adjust the output
signal to 100% by [72] Output Span fine adjust.
3) Again set the simulated input to 0%, confirm the output
signal.
4) If output signal is shifted, repeat the procedure from 1) to
3).
