4.4 LEDs
The LEDs on the ↑Person Machine Interface signal 'Events' and conditions. In
addition, the LEDs support the operator's orientation. The LEDs can light up in red,
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.
