Troubleshooting - Friendly Robotics robomower RL350 Service Manual

6.1.3 Set Country
When a mower is first placed in operation, by default the customer is required to 'Set Country'
prior to the mower operation. This setting helps define the area of the world in which the mower
is operating in order to better define the magnetic field of the earth, which is used by the
Robomow for navigation. This option would be used to change a country where the customer
inadvertently selected the wrong country prior to the first operation or when a main board has
been replaced under a service repair.
6.1.4 DK Calibration
When a mower is first placed in operation, by default the customer is required to perform DK
(direction keeper) calibration' prior to the mower operation. DK calibration is the process of
defining the detail level of magnetic north for the system. It is done at the users lawn and is only
required to be done once. This option would be used if the mower has been moved to a new
location over 160 km (100 miles) from the original location and when a main board has been
replaced under a service repair.
6.2 TESTS
6.2.1 Wire Sensors
Wire sensors is a diagnostic process that tests the operation of the four wire sensors on the mower.
It has two levels of testing, basic and advanced. Under the basic testing it is a 'pass-fail' test with
a fault code listed for the failure message. The advanced testing shows the physical reading of
each of the four wire sensors, which on occasion may be helpful, is troubleshooting. Typically,
the basic test is sufficient.
6.2.2 Rain Sensor
Rain sensor is a diagnostics process that tests the reading of the rain sensor on the Manual
Controller.
3 numbers are displayed in the test:
1) The left number is the rain sensor reading (the actual reading received from the rain sensor – it
is updated every 5 seconds).
2) The middle number is the rain sensor sensitivity, which enables to set the sensitivity of the rain
sensor in which the mower will detect rain below the threshold set. The default sensitivity set
in the factory is 7, it means that in any reading below 7 the mower will detect rain and will not
operate.
3) The right number is the rain sensor status when 0 means that rain sensor's existence is
unknown, 1 means that rain sensor does not exist and 2 means that rain sensor exists.
6.2.3 Direction Keeper
Direction keeper is a diagnostic process used to test the DK system or on-board compass (called
the flux gate). It has two levels of testing, basic and advanced. Under the basic testing it is a 'pass-
fail' test with a fault code listed for the failure message. The advanced test will show the physical
readings of the compass and is seldom used.
6.2.4 Drive Motors
Drive motors is the process of testing the drive motors and odometer system of the mower. It has
two levels of testing, basic and advanced. The advanced testing is not functional in this system.
Under the basic testing it is a 'pass-fail' test with a fault code listed for the failure message.
