CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Confirm that the wire insulation tubes are not caught in
the clamp.
3) Check DIP switch setting.
4) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
5) Input: Check that the input signal is within 0 – 100% of
the full-scale.
6) Output: Check that the load resistance meets the de-
scribed specifications.

■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal while the control input is
TRACK. 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, recalibrate the
unit using the PC Configurator Software (model: M6CFG).
