OUTPUT RANGING
The internal DIP switch setting is required to select output
types before setting a precise output range using PC Con-
figurator Software (model: W2CFG).
For detailed information on the PC configuration, refer to
the W2CFG users manual.

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 potentiometer wires are broken, the output goes
over 100% (below 0% with downscale) due to burnout
function. Confirm the status indicator LED pattern and
check leadwires in such a case.
5) Output: Check that the load resistance meets the de-
scribed specifications.
6) LED: Confirm that the LEDs indicate the normal operat-
ing mode.
STATUS INDICATOR LED
Combinations of the three front LEDs (LD1, LD2, LD3) indicate the transmitter’s operating status by different blinking pat-
terns.

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 using the PC Configurator
Software (model: W2CFG).
