INPUT/OUTPUT RANGING
The internal DIP switch setting is required to select input
and output types before setting a precise range using PC
Configurator Software (model: M6CFG).
For detailed information on the PC configuration, refer to
the M6CFG users manual.

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.

MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes.
8
• For math functions:
Apply the input signals which should lead the calculated
results as 0%, 25%, 50%, 75% and 100%.
• For Hi signal selector functions:
Apply 0%, 25%, 50%, 75% and 100% signal at Input 1
while maintaining 0% at Input 2. Then apply 0%, 25%,
50%, 75% and 100% signal at Input 2 while maintaining
8
0% at Input 1.
• For Lo signal selector functions:
Apply 0%, 25%, 50%, 75% and 100% signal at Input 1
while maintaining 100% at Input 2. Then apply 0%, 25%,
50%, 75% and 100% signal at Input 2 while maintaining
100% at Input 1.
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 us-
ing the PC Configurator Software (model: M6CFG).
