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 During this test, the horn will sound briey and the scrub deck and squeegee will move if they are in the up position. If the hopper is not in
the down position it will also move slightly. Make sure that all persons are away from these 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.
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, and solution tank empty switches may also be tested in this mode. The corresponding
indicators will indicate the state of each of the inputs.
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 20 will be indicated.
Reset of All Programmable Parameters to Factory Default Settings:
To reset all of the above parameters to the factory defaults, perform the following steps:
1 Turn the main power key switch to the off position.
2 Press and hold the all three scrub system switches (scrub off, pressure increase, & pressure decrease).
3 While holding all three switches turn the main power key switch to the on position.
4 Continue to hold all three switches until all indicators turn off and the status display shows “d” (approximately two seconds).
5 Release all switches.
6 The programmable parameters are now restored to the default values.
7 It will now be necessary to reprogram the throttle neutral position. Refer to the proper section above.
8 To exit this mode, turn the main power key switch to the off position.
