Indicator
Condition Meaning
DIO 1-8 ORANGE Digital input ON
DIO 1-8 FLASHING ORANGE
– Mostly On
Update Failure – Failsafe state On
DIO 1-8 FLASHING ORANGE
– Mostly Off
Update Failure – Failsafe state Off
AI 1 & 2 #1 ORANGE Analog input current indication
AI 1 & 2 #2 ORANGE Analog input voltage indication
AI 1 & 2 FLASHING ORANGE Duty cycle relative to the analog reading
Slow =4mA, Fast=20mA
AI3 & 4 ORANGE Analog input current / voltage indication
AO1 & 2 ORANGE Analog output current indication
LED’s display the status of each of the eight digital inputs (If the LED is lit then the input
is on).
If the DIO are used as outputs then the LEDs will, display the status of each of the
digital output (If the LED is lit then the output is on).
Two LEDs exist for each Differential analog input (Channel 1 & 2). The first is used to
indicate the set point and the second whether the analogue input is reading zero or
negative.
For each of the single ended analog channels, the LED indicates when the analogue
input loop is in loop mode.
The two lowest Analog output LEDs are in series with the analog Output and will
indicate the output current. (Dim for 4mA Bright for 20mA).
Ethernet Indications
On the end plate, the ethernet socket incorporates two LED’s These LEDs indicating
the Ethernet status
100M – GREEN LED indicates presence of a 100 Mbit /s
Ethernet connection, with a 10 Mbit /s connection the LED will
be off.
LINK – ORANGE indicates an Ethernet connection and LED
briefly flashed off with ethernet activity.
