Chapter 5 - Diagnostics and Toolkit

1 5 - 1 5. Diagnostics The Diagnostics section of the Service Guide help to perform Diagnostics in case of problems affecting the operation and to pinpoint about the source of the problem. The Diagnostics can be done directly through the Service menu in the Robomow or through the Toolkit software that gives more detailed information in one screen. The Toolkit and the Service menu in Robomow have a series of self-diagnostic tests that allow it to pinpoint problems or test systems affecting the operation. By entering the specific system or component test, it will display either a Pass or Fail message or display a fault code, which is referenced in Section to determine the nature of the problem. This section closely cross-references with Section 3, Troubleshooting. In Section 3, many of the troubleshooting flow charts request a specific diagnostic test to be performed.

2 The results of each of these diagnostic tests are then used to determine the system or component of failure. This section outlines the procedure for performing these tests as well as an interpretation of the results, found in the Fault Code Tables, Section Contents Subject Page General 5-2 Service Key 5-3 Toolkit Setup and Main 5-6 Toolkit 5-10 System 5-10 5-16 5-17 5-18 5-19 5-20 Service menu 5-24 Settings 5-24 Calibration 5-29 Testing 5-31 Diagnostics fault 5-35 Operation Stop Cause 5-37 Battery Voltage 5-40 Charging Current 5-42 5 - 2 Min 2m ( )Min 3m (10ft)Min 2m ( )Min 3m (10ft) General Test The General Test is a basic test that should be performed whenever a technician initiates a service repair on a Robomow. The test is designed so that most common problems found in normal operation will be readily apparent.

3 The General Test should be performed regardless of whether any work was actually performed out on a unit. This ensures a Duty of Care to the customer, and will also serve to insure that all safety systems are working properly prior to a customer using the unit. The General Test should also be performed after any service routine was performed. This will insure that the maintenance was performed correctly and that no additional problems were introduced to the unit during the service routine. The General Test and certain of the other Diagnostics tests need to be performed in a simulated lawn with the layout as shown below: A. Remove batteries fuse from the Robomow and perform a mechanical inspection: 1. Check the operation of the cutting height adjustment. 2. Confirm the front cover chassis, operating panel and gear cover are closed well in its place. 3. Check that the blade is sharp and securely attached. 4. Check the operation of the front wheel by insuring it is free to rotate in all directions.

4 B. Clean the unit using compressed air; particularly the mowing decks. A damp cloth and a wooden stick can also be used to remove stubborn dirt and debris. Do not wash with a hose. C. Insert the batteries fuse and perform the following tests: 1. Check that the operating LED illuminates when the fuse is inserted. 2. Check that the operating panel display and buttons are working properly. 3. Slightly lift the front of the unit and insure that the unit announces the Front Wheel lifted. Repeat the same test by holding the Front Wheel pressed so it will not activate and lift Robomow to more than 60 degrees to verify the tilt sensor is activated. 4. Confirm that the bumpers are functioning correctly by pressing them and hear the beeps. 5. Check charging using a Power Supply or through the Base Station. SAFETY FIRST! Before completing the following tests, insure that the test area is clear of persons and obstacles. Remove all floor debris to prevent it from being thrown by the rotating blade.

5 Keep feet and hands away from the blades and the drive wheels when testing. Figure Simulated Lawn for General Test 5 - 3 D. Using the Remote Control, drive the Robomow manually forwards, backwards, left and right and perform the Drive motor test under the Service menu. E. Manually activate the mowing motors and perform the Mowing test under the Service menu. F. Operate the Robomow automatically in the simulated lawn. Verify it follow the perimeter wire in edge mode and move in a straight lines when it moves inside the area in Scan mode. Service Key The Service Key is a function in the Robomow software that allows a service technician to access Diagnostics and service functions. These menu functions are not available to the end user. There are two ways to unlock the service password protection: Formula that calculates the required password code based on a counter that is changed every 2 days and called Service Counter.

6 Master code: 01210 When you are asked to enter the password code the Service Counter is displayed at the right side of the display inside the brackets. In case of instructing the customer to enter the Service menu, it is recommended to use the Service Counter and not the Master code in order to prevent the user to reenter the Service Menu in the future. The table in the next pages shows the code required for every Service Counter: 5 - 4 Service CounterService PasswordService CounterService PasswordService CounterService Password00000052053561042152810000153055 6510521945200006540577810622366300015550 5995107227914000285606216108232205000455 7064411092365360006658066701102409070009 1590690311124531800120600714011224976900 1536107381113254251000190620762611425878 1100231630787511526335120027664081281162 6796130032565083851172726114003786608646 1182773015004356708911119282031600496680 9180120286801700561690945312129161180063 0700973012229646190070371100111233013520 0078072102961243062821008617310585125311 2522009467410878126316262301035751117512 7321312401128761147612832640250122577117 8112933153260132678120901303367027014317 9124031313419128015408012720132347162901 6538113041133352453001770821336613435778 3101891831369513536315320201684140281363 6856330214585143651373740134022788614706 1383795035024158715051139385033602556881 5400140390603702701891575314139621380285 0901611014240186390300391164711434075540 0316092168361444132841033219317205145419 0542034869417578146424864303655951795514 7430714403828961833614843660450400597187 2114944253460418698191101504485047043719 9195031514545148045601001990015246056490 4753101203011534666550049501022070615447 27851051511032111515547895 Service Counter and password: 5 - 5 Service CounterService PasswordService CounterService Password15648516207854911574914120886320 1584977020987153159504032108799016051040 2118883116151681212896761625232621390525 1635297521491378164536282159223516554285 2169309616654946217939611675561121894830 1685628021995703169569532209658017057630 2219746117158311222983461725899622399235 1735968522400129174603782250102617561075 2260192717661776227028321776248122803741 1786319022904654179639032300557118064620 2310649218165341232074171826606623308346 1836679523409279184675282351021618568265 2361115718669006237121021876975123813051 1887050023914004189712532401496119072010 2411592219172771242168871927353624317856 1937430524418829194750782451980619575855 2462078719676636247217721977742124822761 1987821024923754199790032502475120079800 2512575220180601252267572028140625327766 2038221525428779204830282552979620583845 20684666 Service Counter and password (con.)
