Alarms, faults and system messages
8
The inverter has the following diagnostic types:
●
LED
The LEDs at the front of the inverter immediately inform you about the most important
inverter states.
●
System runtime
The system run time is the total time that the inverter has been supplied with power since
the initial commissioning.
●
Alarms and faults
Every alarm and every fault has a unique number.
The inverter signals alarms and faults via the following interfaces:
–
Fieldbus
–
Terminal strip with the appropriate setting
–
Interface to the BOP-2 or IOP-2 operator panel
–
Interface to STARTER or Startdrive
●
Identification & maintenance data (I&M)
If requested, the inverter sends data to the higher-level control via PROFIBUS or
PROFINET:
–
Inverter-specific data
–
Plant-specific data

Operating states indicated on LED
LED status indicators
The Control Unit has number of dual-colour LEDs which are designed to indicate the
operational state of the Inverter. The LEDs are used to indicate the status of the following
states:
●
General fault conditions
●
Communication status
●
Input and Output status
●
Safety-Integrated status
The location of the various LEDs on the Control Unit are shown in the figure below.
