Troubleshooting

5-1-1 Possible Device Problems

Two possible types of trouble are as follows.

•

No display

- No display appears after the unit is switched on.

- The screen disappears during RUN mode.

- The screen display is not normal.

•

Touch panel doesn't respond

The touch panel does not react when pressed, or its reaction time is
abnormally slow.

• Because of the danger of an electric shock, be sure

the power cord is not connected when wiring the
unit.

• When changing the backlight, since there is a dan-

ger of an electric shock or burn, be sure to turn the
FP off and wear gloves.

WARNINGS

Troubleshooting procedures for these problems are described in the flowcharts
on the following pages.
