INDICATOR LEDS
There are six Indicator LEDs which signal power, I/O and EtherNet/IP communication activity
and are visible below the M12 connectors (excluding AUX).
PWR-IN / ID-NET
The Power LEDs are blue when power is correctly applied to the QLM500.
These LEDs are red if power polarity is incorrect. In this case the QLM500 and the
connected reading device are protected.
If external I/O devices are powered through QLM500 (connected to +V I/O
and -V I/O), they are not protected from polarity inversion.
CAUTION
TRG
The Trigger LED is yellow and it is on when the Trigger (presence sensor) photocell is
activated.
I/O
The I/O LEDs reflect the activity of the supplemental I/O devices connected to the reading
device through the QLM500.
The Input 2 LED is yellow and it is on when the supplemental photocell is activated.
The Output 1 LED is red and it is on when the reading device Output 1 is activated.
The Output 2 LED is green and it is on when the reading device Output 2 is activated.
ETH1
There
are
two
below ETH1 which act as
the 'EtherNet/IP Network
Status' indicator and the
'Port

Link
Activity'
indicator. They are driven
according to the following
tables.
ETH2
There
are
two
below ETH2 which act as
the 'EtherNet/IP Module
Status' indicator and the
'Port
2
Link
Activity'
indicator.
They are driven according
to the following table.
