Power Box is beeping every 1 sec - Cut Wire indication
For RS, TS, MS models
For RC, TC, MC models
Power Box is beeping 3 times with 1 second of silence
Wire is too long / bad connection indication
Q1. Check that all connections between the Power Box through the 20 meter extension cord to the Base Station, are all connected well (Is the Green Plot connector of the lawn connected)?
If Yes – Proceed to Q2.
If No – Secure all connectors back in place and observe if the warning
persists.
Q2. Make a small lawn loop using the second green plot connector that was supplied with the robot, such as with the image to the right. Does the warning still persist?
If Yes – Proceed to Q3.
If No – Proceed to Q5.
Q3. Take the Power Box and connect it directly to the Base Station Head (with the wire loop still connected). This will bypass the 20 meter extension cord.
Does the warning still persist?
If Yes – Proceed to Q4.
If No – Replace the 20 meter extension cord.
Q4. Extract the Base Station Head out of its place, and make sure the power plug is inserted into its socket securely.
Does the warning still persist?
If Yes – Replace Base Station Head.
If No – Put the Base Station Head back in place and observe whether the failure continues to occur.
Q5. Check for wire loop disconnections in the lawn. You can use an AM radio
to search for disconnections more easily. For more detail,
see this article How Can I Find Disconnections In The Wire Installation Loop?
If Yes – Fix the wire using official splicing connectors, such as with the image to the right.
If No – Check with the Resistance meter (DVM) the resistance of the entire loop. The factor is about 1 W per 40 meter wire. Proceed to Q6.
Q6. Is the resistance higher than 40 W ?
If Yes – There is a disconnection somewhere in the wire loop.
If No – Send the Power Box and Base Station Head to the nearest service provider for analysis.
Q1 - Check all connections between the Power Box through the 15m extension cord to the Base Station, as described below:
- Check the connection between the DC Power Supply cable and the 15m extension cable. If there is friction of the rubber sleeve, make sure you push the DC plug all the way in.
It is recommended to disconnect it and push it all the way inside again.
- Check the connection of the 15m extension cable to the Base Station.
- Check the connection of the two ends of the Perimeter Wire to the green plot connector and make sure the plot connector is connected to the Base Station at the right polarity (direction).
If Yes – Proceed to Q2.
If No – Secure all connectors back in place and observe if the warning persists.
Q2 - Create a small loop of wire (using the extra green plot connector supplied with Robomow), and connect it to the Base Station (see image) - instead of the long lawn wire that is currently connected.
This simulates a small lawn (without a wire break) in order to verify whether the fault is along the Perimeter Wire is installed on the lawn or in the connections between the Power Box and the Base Station.
Does the warning still persist?
If Yes – Proceed to Q3.
If No – Proceed to Q6.
Q3 - Replace the base station board.
Does the warning still persist?
If Yes – Proceed to Q4.
If No – Proceed to Q6.
Q4 - Replace the power box.
Does the warning still persist?
If Yes – Proceed to Q5.
If No – Proceed to Q6.
Q5 - Replace the 15m extension cable.
Does the warning still persist?
If Yes – Send the Power Box / Base Station / 15m extension cable to the nearest service provider for analysis.
If No – Proceed to Q6.
Q6 - Check for wire loop disconnections in the lawn. You can use an AM radio to search for disconnections more easily.

“Were disconnection(s) found in the wire?”
If Yes – Fix the wire using official splicing connectors, as in the following image.
If No – Check with the Resistance meter (DVM) for the resistance of the entire loop. The factor is about 1 W per 40 meter wire.
Proceed to Q7.
Q7 - Is the resistance higher than 40 W ?
If Yes – There is a disconnection somewhere in the wire loop.
If No – Send the Power Box and Base Station to the nearest service provider for analysis.
Power Box is beeping 3 times with 1 second of silence - Wire is too long / bad connection indication
This failure relates to a poor wire connection, which may cause oxidation and high resistance. A poor connection is caused by not using a waterproof connector to splice the wire or by using the right connector but the insulation removed is too long and thus the part left outside the connector is exposed to water and caused it to damage quickly.
Q1 - Is it a new installation or have changes been made in the lawn/installation cable lately?
If Yes – Make sure the installation was done according to the written instructions in the Operating and Safety Manual. Check specifically that the installation cable is not longer than 600 meters. If the cable is longer than 600 meters (but up to 800 meters long), use the “Adaptor for large perimeter S” - Part Number SPP6117, which can be ordered by special request.
If No – Proceed to Q2.
Q2 - Make a small lawn loop using the second green plot connector that was supplied with the robot, such as with the image below (according to your product family). Does the warning still persist?
If Yes – Replace Power Box and Base Station Head/Board.
If No – Proceed to Q3.
Q3 - Is the wire used for the installation the official wire supplied with the robot?
If Yes – Proceed to Q4.
If No – Use only the official wire packages for the installation.
Q4 - Disconnect the plot connector from the Base Station and check with a Resistance meter (DVM) the resistance of the entire loop. The factor is about 1 W per 40 meters of wire.
Is the resistance higher than 40 W?
If Yes – Proceed to Q5.
If No – Replace the Power Box and Base Station.
Q5 - Check for disconnections in the wire installation loop buried in the lawn.
