The REF 54_ feeder terminal offers eight alarm LED indicators to be configured
with the Relay Mimic Editor. The LED colors are green, yellow or red, and their use
can be freely defined (for defining the ON and OFF state texts, refer to section
"MIMIC configuration" on page 24). Three basic operation modes are supported:
• non-latched light
• latched-steady light
• latched blinking light
Alarms can be acknowledged remotely, locally or by using logic.
The alarm channels include time tagging for detected alarms. The time tagging
principle used depends on the operation mode.
The alarm channels are seen as function blocks in the feeder terminal configuration:
