6.24 Connecting Message Devices for Events and Warning
Messages
One of the following events and warning messages can be displayed for each multi-function relay:
• The generator is running and is connected.
• Voltage and frequency of the electricity grid are within the range for connection.
• An off-grid inverter displays an error message of level 2 or higher. Only the error messages
within a cluster are evaluated.
• An off-grid inverter outputs a warning. Only the warnings within a cluster are evaluated here.
• The off-grid inverter/cluster is in operation.
• The off-grid inverter/an off-grid inverter in the cluster is in derating mode.
If you display the states of the off-grid inverter with a multi-function relay, connect the message devices
as follows:
1. Connect the control to the multi-function relay (see Section 6.18"Assignment of Multi-Function
Relay",page54).
2. Enter the function of the multi-function relay used in the configuration table
(see Section 7.10.1"Use of the Multi-Function Relays",page90). Note one of the following
values here:
Different control logic for error messages of level 2 or higher
• If an error message of level 2 or higher is present, the multi-function relay switches
to the NC position.
• If no error message is present, the multi-function relay switches to the NO position.
This ensures that the error message will also be displayed in the case of automatic
shutdown.
Value Output
GnRn The generator is running and is connected.
GdOn Voltage and frequency of the electricity grid are within the range for
connection.
Error An off-grid inverter displays an error message of level 2 or higher.
Warn An off-grid inverter outputs a warning.
Run The off-grid inverter is in operation.
Overload The off-grid inverter is in derating mode.
