Screen is
dim
1) The power voltage may be low.
2) The contrast is set too low.
3) The backlight is off due to the [Back-
light Auto–off] setting in the [Setup] of
the GT10 configuration settings in
GTWIN.
1) Supply 24V DC 0.3 A.
2) Bring up the system menu and adjust
the contrast.
3) Touching any area of the screen lights
that area. If a switch part is set on the
touched area, the area will not light
even if touched. To change the setting,
change the content of the backlight
auto–off settings.

Date / time
display is
incorrect
1) The GT10 internal clock is incorrect.
2) Clock data is lost when power is off
because the secondary battery is not
set to ON.
3) The secondary battery is set to ON
but due to long periods with the power
off or on (over 10 days), the clock data
has been lost.
4) The PLC’s internal calendar timer
used as a reference is incorrect.
1) Bring up the system menu and adjust
the clock.
2) Turn off the power, and after turning on
the No. 1 operation mode setting
switch on the back of the GT10, power
up the unit and adjust the clock.
3) Turn on the power and set the system
menu clock data. In cases when pow-
er is off for approx. 10 days, it takes
around 2 hours for the secondary bat-
tery to fully charge.
4) Adjust by rewriting the value in the
PLC’s internal calendar timer.
