“Blocked”.
When the robot does not perceive the cable or a crash for 5 minutes, it tries to
turn by 90° three times consecutively then it stops and displays “Blocked”.
Generally, it happens when the robot is held up into a hole or if the wheels are
loose.
Bump error
Blocked crash
-
Check the correct positioning of the covering
-
From the service menu check which bump group is damaged
-
Check inside the bump group that a spring has not come off
-
Check the cabling properly inserted in the right display connector
Safety on the handle not working
In case the safety blade sensor does not work, check the following points:
-
User service menu. Check it is enabled.
-
Turn it on and off.
-
Control the wiring is well connected to handle.
-
Verify link from display to handle with a tester.
-
Verify with debug the obtained values
“Clock Error”
-
If the robot does not correctly upgrade the date and the time, it is
necessary to replace the mother board.
Sync Error
The error message “sync error” is displayed only in robots which manage the
sinusoidal signal. In that case, the message shows that the sinusoidal receiver
is not recognized. The reasons may be the following:
-
The sinusoidal receiver is not correctly inserted. Any remove or
insertion operation should be done with the batteries unplugged.
-
Broken F1 fuse in the mother board
-
Broken sinusoidal receiver
-
Faulty mother board
“High Battery”
-
Should the robot display too many errors, it is necessary to check the
output tension of the charger. If it is correct, maybe there is a failure
in the mother board Voltmeter. As a result, you should replace the
mother board.
The Robot switches off
Check the following things:
-
Fuses connection is not good. Take them off, clean and tighten them.
Above all fuse F3.
-
Control the battery wiring.
-
Motherboard with a faulty relè and bulges. White RL1 near to
connectors wheel motors.
-
Keyboard with key ‘off’ in short circuit.
-
Display with moisture on the keyboard connector.
-
Control the battery. See technical advanced information
Research of the perimeter wire
interruption
If the perimeter is interrupted and the Green led is fixed, you have to perform
the following tests:
-
Check the fuse inside the transmitter and eventually replace it.
-
Check the ohms of the perimeter wire with a tester. Then check the
impedance disconnecting the white connector (A) from the 6-pin
transmitter (+Charger, -Charger, Perimeter, Perimeter, Not Used,
Not Used), check the central pins. The impedance should be under 20
ohm, otherwise the interruption may be under the base or on the
perimeter.
It is then necessary to check the impedance by disconnecting the
