Program Options (REV)
Program options must be set whenever the Main Controller has been replaced.
• Scrub Deck Type
- This function configures the control unit current settings and flow rate settings for
each of the scrub deck types. Note: After replacing the controller the machine will not operate until a deck
type has been selected.
• Chemical Selection
- Used to let the controller know whether the onboard detergent dispensing system
has been installed and which market area the machine is in. The market area determines whether to
show the detergent dilution rate as a ratio (US-style) or percentage (EU/Global-style) .
• Vacuum motor quantity selection
- The main controller must be programmed for the number of
vacuum motors installed so that the current overload protection and recovery tank full will function
properly.
• Low Voltage Cutout Selection
- The purpose of the special low battery voltage cutout function is to
help prolong battery life. The scrub deck will be raised and the brush motors and solution solenoid valve
will turn OFF automatically and cease to function when the batteries discharge to the selected cutout
level. The cutout level is adjustable between two settings. The standard setting (wet cell/lead acid) is
20.55 volts and alternate setting (gel/maintenance free) is 21.75 volts.
• Maximum Scrub Speed
- The control system is programmed to limit the maximum speed while
scrubbing to a value less than that allowed for driving when not scrubbing (100%, 90%, 80%, 70%, and
60%).
• Lock Out Brush Pressure
- Used to lock out any brush pressure settings Low, Medium, High, Low and
Medium, Low and High, High and Medium. During normal operation, the pressure setting(s) that are
locked out will not be able to be selected. Default is “None”
• Lock Out Solution Flow Rate
- Used to lock out any solution flow rate settings: Low (Normal), Medium
(Heavy), High (Extreme), Low and Medium, Low and High, High and Medium. During normal operation,
the flow rate(s) that are locked out will not be able to be selected.
• Recovery Tank Full Enable/Disable
- Used to enable or disable Recovery Tank Full automatic shutoff
feature. Enable means that the automatic shutoff feature is turned on; disable means that the automatic
shutoff feature is turned off.
• Chemical Ratio Bias
- Used to increase or decrease the chemical mix rate by 10% to achieve a more or
less concentrated mix than that determined by user programmed ratio
• Deck Down Time Period Adjustment
- When the scrub on/off switch is pressed, the control unit
will automatically lower the deck for a specified amount of time. The time that the deck is lowered is
adjustable from 1 second to 5 seconds in 0.1 second increments.
• Restore Factory Default
- This submenu should reset all parameters stored in the EEPROM except
Brush on Time. Note: after restoring factory defaults, all of the program options must be reviewed and set
appropriately. The machine will not work until at least the deck type is selected.
• Display Revision Level
- The LCD display will show the revision level of the software in the control
board.
• Fault Recall
- Whenever the control unit detects an electrical system fault, one or more error codes are
displayed and stored in the EEPROM. If it is desired, the error code (if any) from the previous operation
for the machine can be recalled for troubleshooting purposes. If no fault code is present, the display will
show a “-“
• Fault Detection
- Normally, the main control unit will perform checks of the electrical system during
operation. If a fault occurs in a particular system, that system (and possibly others) will be shut down.
This can make troubleshooting the system difficult. This option will allow service personnel to disable
some of the fault detection checks to facilitate troubleshooting. This will not disable the over-current
protection on any of the systems.
