You will get that alarm if the net wrap duckbill is not in the home position. With the monitor turned on, push the “Retract” button and see if the error goes away. If possible, do this with the net wrap cover of the baler open so you can see if the duckbill is moving. Since this is a new to you baler, I would recommend testing the wrap cycle by pushing and holding the “Wrap” button until the monitor gives the long beep signifying that the wrap cycle is beginning. The duckbill should move to the full insert position, stay there for a bit, then it should retract fully to the home position and give you an error as the net wrap did not start wrapping. Push the “Clear” button to clear the error. I would do this several times to verify that the components of the duckbill/actuator/net knife are working properly, and it also verifies a good electrical connection at the tractor. These balers MUST be connected directly to the battery with clean hardware.
