For RS Models
Step 1 – Has this happened more than once?
If Yes – Proceed to Step 2.
If No – Let the robot continue to work, and if it happens again, check battery voltage through mower’s service menu.
Step 2 – Make sure that the Safety Switch is set to On, then press the Go button. Did the robot wake up?
If Yes – Proceed to Step 4.
If No – Check if the fuse is burnt, and proceed to Step 3.
Step 3 – Is the fuse burnt?
If Yes – Replace the fuse and check if it burns immediately again (this is a fast acting 20A/32V fuse that can be found in local electricity shops). If the fuse gets burnt immediately again, check the fuse wires going to the safety/main switch to see if any part of the wire is browned/burnt. Check the fuse housing as well and smell it to find traces of being burnt. If burnt, Replace Fuse Housing and Battery Cable. The main switch is part of this cable.
If No – Insert the mower into the Base Station, turn the Safety Switch to Off, and wait a few seconds until the screen turns on with the message “Switch On”. Proceed to Step 4.
Step 4 – Is there a “Switch On” message on the screen?
If Yes – Wait 30 minutes to let it charge fully (it may take up to 24 hours). Then turn safety/main switch On and observe if this happens again. If it happens again, contact customer support.
If No – Remove the GSM.
Did removing the GSM help and mower now works fine?
If Yes – Replace the GSM and install a good new one. Test it and make sure it transmits.
If No – Proceed to Step 5.
Step 5 – Check the below parameters in the same order as written in the table. Once the root of the failure is found, stop checking the rest of the parameters, and replace the faulty part.
