PROGRAMMABLE CONTROL OPTIONS
Control System Self-Diagnostic Mode:
If problems with the electronic control system are suspected, this self-diagnostic mode may help isolate the problem. When this mode is activated,
the control unit will activate each one of the outputs in sequence and test for short circuits, open circuits, or overload conditions. This mode will also
provide an easy test for the touch panel switches and indicators.
If an abnormal condition is encountered with one of the outputs, an error code will be displayed. A listing of error codes is provided at the end of this
section.
1 CAUTION! During this test, the horn will sound briefl y and the various motors will turn on momentarily. Make sure that all persons
are away from ALL moving parts of the machine to prevent injury.
2 Turn the main power key switch to the off position.
3 Press and hold the side broom down/on switch switch.
4 While holding the side broom down/on switch, turn the main power key switch to the on position.
5 Continue to hold the side broom down/on switch until all indicators except the side broom down/on indicator turn off (approximately two
seconds).
6 Release the side broom down/on switch.
7 The control will now activate each output in sequence and perform the tests mentioned above.
8 If no abnormal conditions are detected, the display will now show "-". Go to step 10.
9 If abnormal output conditions were detected, the display will now show the error code(s). An example of how two codes, 6 and 18, would be
displayed is as follows:
• The display will show "E" followed by a brief blank period
• The display will show "0" followed by a brief blank period
• The display will show "6" followed by a slightly longer blank period
• The display will show "E" followed by a brief blank period
• The display will show "1" followed by a brief blank period
• The display will show "8" followed by a long blank period
• The above sequence will repeat
10 To test any of the control panel switches, press the desired switch. The indicator for that switch should illuminate. If not, consult the service
manual trouble-shooting section.
11 The hopper limit, main broom, recovery tank full, solution tank empty, hydraulic fi lter, hopper temperature, and dust control fi lter switches may
also be tested in this mode. The corresponding indicators will indicate the state of each of the inputs. The speed controller fault code status light
will indicate the state of the speed control fault output (a periodic fl ash is normal). The Battery status indicators will indicate the following: red
indicator = state of seat switch, yellow indicator = state of forward/reverse signal from speed control, green indicator = state of reverse signal
from speed control. The hourmeter display will indicate the battery voltage.
12 To exit this mode, turn the main power key switch to the off position.
NOTE: If the machine is not equipped with an optional back-up alarm, an error code 59 will be indicated. Also, this test does not include
the light circuit.
