7.2.3.1 Description of LED HMI functionality
GUID-C643D737-6D44-44C9-818F-EB73C4CA49E4 v1
On the top-plate of each SAM600 module, there are three status LEDs which have a fixed
function and cannot be configured.
The function of each LED is as follows:
• The green LED (READY) indicates the operation status of a SAM600 module.
• The yellow LED (WARNING) indicates any warning caused by an issue related to a SAM600
module.
• The red LED (ALARM) indicates severe hardware failure or software malfunction of the
SAM600 module.
