CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Input signal and power input voltage: Check wiring
across M2EXS and self-synch as follows; terminal 1 – S1,
terminal 2 – S2, terminal 4 – S3, terminal 10– R1, and
terminal 11 – R2.
Be sure that the connection for R1 and R2 of the self-
synch. When the connection is reversed, the signal condi-
tioner output will be shifted by 180°.
4) 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. When the output is out
of tolerance, recalibrate the unit as explained in the users
manual of the M2ECFG configurator software. Or follow
the procedure shown below.
•
INPUT FINE ADJUSTMENT
Set the input signal to 0%, and adjust the input to 0% by
[06] Angle offset.
•
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).
