Friendly Robotics robomower RL350 Service Manual page 89

Problem Encountered
Robomower does not detect
the Charging Station contacts
and/or 'Front wheel problem'
is displayed when the mower
is in the Docking Station
Follow the steps below:
1. If the mower doesn't detect the Charging Station, the failure may be found in one of the following:
- Robomower
- Charging Station
- Power Supply
Testing the Robomower:
2.
- Connect the mower to a standard Power Supply (Indoor use only) through the charging socket (placed
below the Manual Controller at the left side) and confirm 'Charging' is displayed for at least 1 minute.
Place the mower out of the Charging Station.
-
Choose 'Charging voltage' under the 'Information' menu; it should be around 14.0 V.
If the voltage is '0' check the following:
- Connections between the Robomow contacts to Connector Board
- Connector Board
- Connection between Connector to Main Board
- Main Board
Take a metal ruler and make shortage between the contacts in the mower side.
If the mower is good, then the voltage should drop down to zero.
If the mower has problem (disconnection, burnt Fuse, faulty Manual Controller Holder Assembly...) then
the charging voltage will stay the same (~14V).
If the mower is good continue to the next step.
Information:
If you measure the voltage on the Charging Station contacts when the mower is out of the Charging
Station, it should be zero.
As you drive the mower to the Docking Station and it reaches the contacts, it will initiate the current
consumption (because it detects the 14V from the mower side).
3. Drive the mower into the Charging Station and confirm it touches the Charging Station contacts.
Leave the Manual Controller out of its place so the charging of the battery will not start.
Probable Cause/Event
'Docking test'
Perform
This test checks the detection of the Docking Station by the Robomower.
- Power supply/charger is not plugged
into the main power supply
- No power to receptacle or main power
is shut off
- Docking Station and/or Robomower
have burnt signs or/and corrosion
- Poor or disconnection of the Docking
Station wires (red and green) to the
contacts
Corrective/User Action
(refer to section 5.4.7).
- Confirm power supply is plugged into the main
power receptacle.
- Check for power to this main receptacle by
plugging in another appliance.
- Turn power on to the main receptacle.
- Disassemble the Docking Station Cover by
unscrewing the screws and check the
connection of the power cable (black) and the
wire connector (green).
- Confirm the 'ON' light is blinking in the
Docking Station when switching on the green
(ON) button.
- Periodically clean the Docking Station and the
Robomower contacts using only a damp cloth.
- Contact your service provider if the contact
should be replaced
- Confirm good contacts in the tabs (end of the
red and green wires) to the Docking Station
contacts.
