Red Light Blinking Slow on the Base Station Head / Wire Too Long Warning

Base Station Head - RS Models

Step 1 – Is it a new installation or have changes been made in the lawn/installation cable recently?

If Yes – Make sure the installation was done according the written instructions in the Operating and Safety Manual, and especially make sure the installed perimeter wire length does not exceed its limits as outlined below:

Model Years Maximum Wire Length Maximum Resistance
2019-2020 Up to 2500 feet (762m) 17.6 Ohms
2018
(using a long wire docking head)
Up to 2500 feet (762m) 17.6 Ohms
2018
(not using a long wire docking head)
Up to 1500 feet (467m) 10 Ohms
2014-2017
(using a long wire adapter)
Up to 2500 feet (762m) 17.6 Ohms
2014-2017
(not using a long wire adapter)
Up to 1500 feet (467m) 10 Ohms

If No – Proceed to Step 2.

Step 2 – Make a small lawn loop using the second green plot connector that was supplied with the mower, or the same green plot connector used now. See picture below. Does the red light blinking continue?

If YesReplace Base Station Head corresponding to your mower’s model year.

If No – Proceed to Step 3.

Step 3 – Disconnect the plot connector from the Base Station Head and check with voltmeter (DVM) the resistance of the entire loop. The factor is about 2.2 Ohms per 330ft (110m) wire. Here are the maximum wire length and resistance for various RS and XR3 models:

Model Years Maximum Wire Length Maximum Resistance
2019-2020 Up to 2500 feet (762m) 17.6 Ohms
2018
(using a long wire docking head)
Up to 2500 feet (762m) 17.6 Ohms
2018
(not using a long wire docking head)
Up to 1500 feet (467m) 10 Ohms
2014-2017
(using a long wire adapter)
Up to 2500 feet (762m) 17.6 Ohms
2014-2017
(not using a long wire adapter)
Up to 1500 feet (467m) 10 Ohms

Is the resistance higher than the max numbers mentioned above per your mower year model?

If Yes – Proceed to Step 4.

If NoReplace Base Station Head corresponding to your mower’s model year.

Step 4 – Check for disconnections or poor connections in the perimeter wire loop in the lawn. See the article Finding a break in the wire.

Step 5 – If you cannot find any bad splices, replace the whole perimeter wire. Install a new one preferably without any splices in it.
