Programming Functions 83Service Manual – Advenger, 2800ST, 3800ST, BR 755, BR 855
Changing Control Board Program Settings
Although the Advenger / BR 755, 855 and ST are delivered with a standard factory preset conguration, there will be times, such as when a control
board is replaced, when battery type is changed, or a different size scrub deck is installed, when some parameters in the control system software
will need to be changed. Most programmable functions are outlined below. For more details, call the Technical Service Department at Nilsk-
Advance.
IMPORTANT
For eld control board replacements, critical settings are highlighted below in bold letters.
Advenger / BR 755, 855 and ST settings that can be changed per the following tables are:
1. Low Voltage Cutout (Depth of Discharge) - 20.55V wet battery or 21.75V gel/AGM battery
2. Scrub Deck size - 28” or 34”
3. Number of Vacuum Motors installed (single or dual conguration - to prevent over current detection malfunction)
4. Maximum speed while scrubbing as a percentage of travel speed (50% - 90%)
5. Recovery Tank Full automatic shut-off disable/enable.
6. Restore factory defaults
7. Fault Recall of previous error codes to aid in troubleshooting.
8. Fault Detection over-ride - disable Fault Detection so systems aren’t shut down while in error state (exception is overload).
9. Solution Flow Rate lock-out
Advenger / BR 755, 855 models allow these additional programming changes to be made via the Hidden Menu:
NOTE: Replacement control boards come with Evergreen (EcoFlex) OFF and AXP/EDS (EcoFlex) disabled.
10. Chemical (Detergent)Selection - Turn AXP/EDS (EcoFlex) Off or On with display indicating US or European (ratio or %) format.
11. Detergent Mode - . Turn on Mode 1 (machine factory preset for US market) to enable standard Evergreen (EcoFlex) mode in which
pressing the Evergreen (EcoFlex) button enables preset ratio for 60 seconds. Turn on Mode 2 (factory preset for the EU market) to run at a
preset ratio. In this mode, pressing the Evergreen (Ecoex) button increments the ratio (solution concentration) to the next stronger level for
60 seconds.
NOTE: To run the machine in a constant user-dened ratio, turn the Detergent Mode to Off and set the chemical ratio by pressing and holding the
AXP/EDS (Chemical) On/Off switch (E).
12. Brush Pressure lock-out - during normal operation, the pressure settings that are locked out will not be selectable.
13. Chemical rate bias - AXP/EDS (EcoFlex) control set to 10% more or less chemical than the user programmed ratio
14. Deck down time - time for which the control system applies 24V to the deck actuator to raise or lower the scrub deck after the Scrub On
switch is pressed (adjustable from 1 to 5 seconds).
15. Backup Alarm volume
16. Horn volume
