The power LED (ON) is on (green) if the module runs properly.
The communication LED (COM1) is on (orange) for 20 ms after sending each message.
If the module receives/sends a lot of messages, the LED can be lit continuously.
LEDs indicating the status of the universal inputs (U1-Un) are lit when the resistance
connected to the input is less than 5
kΩ
(dry contact input is active).
LEDs indicating the status of the digital
inputs (I1-
In) are lit when the input is active.
LEDs indicating the status of the analog
outputs (A1-
An) are lit when the output voltage
or PWM duty cycle is greater than 0.
LEDs indicating the status of the digital
outputs (O1-
On) are lit when the output is
enabled.
WARNING!
The LED also lights up when the voltage connected to the input has a very low
potential.
