Connecting the Control Cable for Autostart Generators
Qualified person
Autostart generators are started and stopped with a contact.
Signal generator or generator control in a cluster
Slaves control the generator less reliably than masters do.
- Connect the generator control preferably to the master.
- In a multicluster system, always connect the signal generator to the master of the main cluster.
Connecting the Generator Control to Sunny Island
Requirements:
- The technical requirements of the multifunction relay must be met ( > Technical Data).
Cable requirements:
- Copper wire
- Conductor cross-section: 0.2 mm² to 2.5 mm²
Procedure:
- When making the following connections, always insert a silicone tube ( > Connecting Relay 1 and Relay 2).
- The default setting of the Sunny Island uses the multifunction relay Relay1 for generator requests. Therefore, connect the control cable to the multifunction relay Relay1 on the Sunny Island. Use the C and NO connections.
- If the multifunction relay Relay1 for generator requests is not available, connect the control cable to the multifunction relay Relay2 on the Sunny Island. Use the C and NO connections.
- If, with more than one Sunny Island, the multifunction relay Relay1 and Relay2 for generator requests are not available on the Master, connect the control cable to a free multifunction relay on slave 1 or slave 2. Use the C and NO connections.
- Enter the configuration Automatic generator request in the table of settings ( > Setting the Functions of the Multifunction Relays).
WARNING
Danger to life from electric shock due to incorrect insulation
In the case of faulty insulation, supposedly de-energized parts or cables may be live. Touching live components or cables can result in death or serious injury due to electric shock.
