7.4.14 Connecting Message Devices for Operating States and Warning Messages
You can connect message devices to the multifunction relays to allow operating states and warning messages from the
Sunny Island inverter to be output. One of the following operating states and warning messages can be displayed for
each multifunction relay:
• The generator is running and is connected.
• Voltage and frequency of the utility grid are within the range for connection.
• A Sunny Island displays an error message of level 2 or higher. Only the error messages within a cluster are
evaluated here.
• The Sunny Island displays a warning. Only the warnings within a cluster are evaluated here.
• The Sunny Island is in operation in the single system.
• The respective cluster is in operation in a cluster system.
• The Sunny Island is in derating in a single system.
• The respective cluster is in derating in a cluster system.
Requirements:
☐ The technical requirements of the multifunction relay must be met (see Section 10 "Technical Data", page 94).
Cable requirements:
☐ Copper wire
☐ Conductor cross-section: 0.2 mm² to 2.5 mm²
Procedure:
2. Go to Section 8.1.5, page 66 and enter the following values in the table for configuration 1.
Different control logic for error messages of level 2 or higher
• When an error message of level 2 is pending, the multifunction relay is deactivated.
• When no error message is pending, the multifunction relay is activated.
This ensures that the error message will also be displayed in the case of automatic shutdown.

Danger to life from electric shock due to incorrect insulation
• Connect the control cable on the Sunny Island to either
multifunction relay Relay1 or Relay2 (see Section 7.5.5
"Connecting Relay 1 and Relay 2", page 55). Use the C and
NO terminals.
Value Output
GnRn The generator is running and is connected.
ExtVfOk Voltage and frequency of the generator are within the range for connection.
GdOn The utility grid is connected in the off-grid system.
Error A Sunny Island displays an error message of level 2 or higher.
Warn The Sunny Island displays a warning.
Run In a single system, the Sunny Island is operating, or in a cluster system, the cluster is operating.
Overload In a single system, a Sunny Island is in derating, or in a cluster system, the cluster is in derating.
