n
When there is no CAN communication or if the I/O module is starting up the LED will
flash five times per second.
n
5V supply for CAN control.
n
24V supply for valves and sensors.
Analogue inputs
n
Green LED indicates 5V and 24V supply voltage.
n
Red LED indicates short circuit to ground of sensor supply voltage.
The supply voltage must be reset after one second when the short circuit is broken.
Digital inputs and outputs
!
NOTE: The left-hand LED has a signal from pin 2 (B) and the right-hand LED has a
signal from pin 4 (A).
