4.4 LEDs
The LEDs on the ↑Person Machine Interface signal 'Events' and conditions. In

yellow, or green. The LEDs can be configured according to customer-specific
requirements.
The LED colors can, for example, signal the following information:
Red
● ALARM
● Activations, e.g., ↑remote transmission, ↑alarm
devices, control function
Yellow
● Fault
● Isolation
● Deactivation, e.g. remote transmission, alarm devices,
control function
Green
● System is in operation
Additional information on the conditions of the LEDs (steady on, steady off or
flashing) can be found in the relevant chapter.
