Moeller MV4 Series - 16 Function and Control Leds

Device Description MV4-670-TA1/2, MV4-690-TA1/2 3-24
Moeller 07/01 AWB-C2700-1347GB
16 Function and Control LEDs
The MV4-600 is provided with different LEDs for indicating the status of the touch controller (
TOUCH
), the
Ethernet interface (
ETHERNET
) and the memory card slots (
MEMORYCARD
), as well as for monitoring the
system voltages (
POWER
). These are arranged on the connector panel.
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 17.2). A reduction of the signal level is caused by the contamination of
the IR transparent plastic frame or the failure of at least one optical element.
If this LED is lit during normal operation (
RUN / ACT
active), clean the plastic frame
at the front of the device (→ Section 17.3).
The LED lights up after the system voltage is switched on. It must go out by the time
the touch controller is initialised by the system electronics (
RUN / ACT
active).
RUN / ACT.
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. 0.3 seconds when the touch screen is
pressed.
ETHERNET
LINK / ACTIVE
The LED (green) is lit if an active network is switched on and detected at the
Ethernet connector. The LED will go out momentarily when there is activity on the
Ethernet.
100MBPS
The LED (green) is lit if the communication via the Ethernet is possible at a
transmission rate of 100 MBit/s.
If the LED is not lit, the transmission rate is 10MBit/s.
MEMORY CARD
MEM. CARD ACCESS
When the LED (green) is lit, the system electronics is accessing both memory
cards.
POWER
SUPPLY OK
When lit, the LED (green) indicates the presence of the system voltages
(+12V and +5V, +3.3V).
If the LEDs are not lit when the system voltage is applied, check the fuse.
