The Micro Panel GF0 provides two LEDs for monitoring the functions of the touch controller (
TOUCH
)
and two other LEDs for monitoring the system voltages (
POWER
). They are located underneath the
COM SLOT.
Description of the LED:
TOUCH
DEF / DIRTY
The LED (red) is lit if during the power up function test of the Touch Screen the
signal level of one or several IR channels is below the minimum level (
→
Section
13.2). A reduction of the signal level is caused by the contamination of the IR
transparent plastic frame or the failure of an optical element.
If this LED is lit, clean the plastic frame on the device front (
→
Section 13.3).
RUN /
ACTUATE
The LED (green) remains unlit when the system voltage is switched on. It will light
up once the initialisation of the touch controller has been successfully completed.
The LED will be deactivated for approx. 0.3s when the touch screen is pressed.
POWER
12V OK
5V OK
When lit the LEDs indicate the presence of the system voltages (+12V and +5V).
If the LEDs are not lit when the system voltage is applied, check the fuse.
When the system voltage is switched on, both Touch LEDs are activated for approx. 0.3 as a function
check.
