FUNCTIONAL DESCRIPTION OF CONTROL BUTTONS:
The controls on theAdvenger were designed with one touch operation in mind. For single pass scrubbing the user can simply depress one switch
and all systems on the machine will be ready to go.
For most single-pass scrubbing operations, the operator should only need to use the top three switches on the control panel. These are the Scrub
System Off, Scrub Pressure Decrease, and Scrub Pressure Increase switches.
Scrub Off Switch (B) - Pressing this switch when the unit is in a scrub mode will cause the following to occur:
• The scrub brushes will turn off and the scrub deck will raise to the up position
• The solution flow will be stopped
• The first time that this switch is pressed, the vacuum/squeegee system will NOT be turned off. This is so that any remaining water may be picked up without
having to turn the vacuum back on. If this switch is pressed a second time (pressed after the scrub system has been turned off) the squeegee will raise and
the vacuum will shut of after a 10 second delay.
• The travel speed limit will return to the transport speed setting.
Scrub Pressure Decrease Switch (D) – If the scrub system is off, pressing this switch will cause the following to occur:
• The scrub system will be enabled with the scrub pressure set to the last used setting and the scrub deck will be lowered
• The vacuum system will be enabled and the squeegee will be lowered
• The solution system will be enabled
• The travel speed will be limited to the scrub speed setting
• As soon as the throttle is moved from the neutralposition the scrub brusheswill start turning andthe vacuum willturn on. If the directionis forward thesolution
flow will start. If the direction is reverse, the squeegee will raise and the solution flow will be stopped.
If the scrub system is already enabled when this switch is pressed, the scrub pressure will decrease. If the switch is held, the pressure will decrement until the
minimum setting of 1 is reached.
Scrub Pressure Increase Switch (F) – If the scrub system is off, pressing this switch will cause the following to occur:
• The scrub system will be enabled with the scrub pressure set to the last used setting and the scrub deck will be lowered
• The vacuum system will be enabled and the squeegee will be lowered
• The solution system will be enabled
• The travel speed will be limited to the scrub speed setting
• As soon as the throttle is moved from the neutralposition the scrub brusheswill start turning andthe vacuum willturn on. If the directionis forward thesolution
flow will start. If the direction is reverse, the squeegee will raise and the solution flow will be stopped.
If the scrub system is already enabled when this switch is pressed, the scrub pressure will increase. If the switch is held, the pressure will increment until the
maximum programmed limit is reached (default = 9).
Wand Switch (I) – This switch is used when an external scrub wand is used. Pressing this switch will turn the vacuum on continuously without
regardtothe throttle position. Itwillalso enable the optionalsolutionpump. If the scrubsystemwas on itwillbe turned off.This includes turningoff
the scrub brushes and raising the scrub deck, turning the solution flow off (to the scrub deck) and raising the squeegee. NOTE: automatic shutoff
of the vacuum motor when the recovery tank is full is disabled when the wand is enabled. The float in the recovery tank will still prevent water from

DESCRIPTION OF INDICATORS ON THE CONTROL PANEL:
In general, the following guidelines apply to the control panel indicators:
A steady red indicator means that the function is inhibited for some reason. For example, if the scrub system is off and the operator is not on the
seat, the scrub system indicator will be red indicating that the system cannot be turned on until the operator is on the seat.
A flashing red or yellow indicator means that a fault has occurred in the particular system.An example of this would be an over-current fault.
A yellow indicator means that the particular function has been enabled but is not currently on. For example, if a scrub mode is selected and the
throttle is in neutral, the scrub system, vacuum, and solution indicators will all be yellow indicating that the systems are enabled and ready to turn
on when the throttle is moved to forward or reverse.
A green indicator means that the particular system is on.
A flashing green indicator means that the particular system is in a delayed-off condition.An example of this is when a scrub mode is selected and
the throttle goes from forward or reverse to neutral. When this happens the vacuum indicator will flash green indicating that the vacuum is still on
but that it will be turning off after the delay period.
Scrub Off Indicator (A):
• This indicator will be green if the scrub system is off and ready to be activated.
• This indicator will be red if the scrub system has been turned off and the scrub deck is not up yet, or if the scrub deck is up and there is no weight on the
seat.
• This indicator will flash red if there is a fault in the scrub system.
• This indicator will be off if the scrub system has been activated.
Scrub Pressure Decrease Indicator (C):
• This indicator will be yellow if the scrub system is enabled but the drive pedal is at neutral and the current scrub pressure is at 2 or more.
• This indicator will be green if the scrub system has been turned on, the current scrub pressure is at 2 or more and the machine is moving in either direction.
• This indicator will be off if the scrub system has been turned OFF or the scrub pressure is set at 1.
Scrub Pressure Increase Indicator (E):
• This indicator will be yellow if the scrub system is enabled but the drive pedal is at neutral and the current scrub pressure is at 8 or less.
• This indicator will be green if the scrub system has been turned on, the current scrub pressure is at 8 or less and the machine is moving in either direction.
• This indicator will be off if the scrub system has been turned OFF or the scrub pressure is set at 9.
Scrub Pressure/Hourmeter Display (G):
The single character display on the control panel is primarily used as a display for the scrub pressure. This display is also used to display the
machine hours and any control system fault codes.
If any of the systems on the machine are on or if the throttle is not in neutral, the display will indicate the scrub pressure setting (1-9). If the scrub
system is off the display will indicate 0.
Upon power-up or if the machine has been idle for at least ten seconds with all systems turned off, the display will indicate the machine hours. The
format for the display of the hours is as follows:
Example 123.4 hours
• The display will indicate 1 followed by a short blank period
• The display will indicate 2 followed by a short blank period
• The display will indicate 3 followed by a short blank period
• The display will indicate _ followed by a short blank period, this is used as a decimal point to indicate tenths of hours
• The display will indicate 4 (tenths) followed by a long blank period
• The display sequence will repeat
Wand Switch Indicator (H):
• This indicator will be green if the Wand Switch has been turned ON.
• This indicator will be off if the Wand Switch has been turned OFF.
Speed Selector Indicator (M):
• This indicator will be green if a scrub mode has been selected and the faster scrub speed has been selected.
• This indicator will be off if the Speed Select Switch has been turned OFF.
Vacuum System Indicator (P):
• This indicator will be green if the vacuum is on.
• This indicator will flash green if the vacuum is in the 10 second delayed-off condition.
• This indicator will be yellow if the vacuum is enabled but the drive pedal is in neutral.
• This indicator will flash yellow if there is a vacuum system fault.
• This indicator will be off if the vacuum is disabled and turned off.
Solution System Indicator (Q):
• This indicator will be green if the solution is on.
• This indicator will be yellow if the solution is enabled but the drive pedal is in neutral.
• This indicator will flash yellow if there is a solution system fault.
• This indicator will be off if the solution is disabled and turned off.

Yellow & Red 31.50-31.99 33.00-33.49
Red 31.00-31.49 32.50-32.99
Flashing Red/Cutoff <31.00 <32.50
NOTE: Refertoservicemanualforselectionofalternatecut-offlevel. Oncethelowvoltagecutoutlevelhasbeenreached(flashingredindicator)the
batteries must be FULLY recharged to reset the battery condition indicator. The scrub system will not function until the indicator has been reset.
DESCRIPTION OF HOURMETER / STATUS DISPLAY
The single character display in the upper right corner of the control panel is primarily used as a display for the hourmeter function. This display is
also used to display the following information depending upon which mode the control is in:
•Error codes*
•Brush pressure adjustment setting for the scrub mode*
•Display of control system default parameters*
•Recovery tank FULLindicator*
* NOTE:Reference(intheElectricalSystemmanualsection)theMainControlBoardTroubleshootingGuideandtheControlBoardSpecialProgramOptionssections.

WHEEL DRIVE SYSTEM
GENERAL FUNCTIONAL OVERVIEW
See Figures 1 & 2. An 840-watt 1.1 HP (permanent magnet) 36V motor/gear transmission combination wheel (M3) unit is used to propel all
machines. ACurtismodel1228PMCsolidstate speedcontroller (A1)regulates (outputs)thevariablespeedFwd/Revwheeldrive motorfunctions.
The controller unit is located to the left of the operator seat, behind the electrical access panel. The potentiometer R1 mounted to the operator’s
foot pedal, inputs to the (A1) controller the machine operator’s desired speed and directional demands.
DRIVE MOTOR SYSTEM CONTROLLER FUNCTION OVERVIEW
See Figure 2. To make theA1 speed controllers internal control circuits operational (power it up) the two switches S1 (key) and S2 (seat) must be
closed. This circuit inputs a positive (+) 36V to the A1 speed controls pin terminal #5 (*KSI). The F2 circuit breaker 45Amp supplies the positive
highcurrent (load)circuitinputtothe B+controller terminal(Brn/Blk wire). Theblackwirefromthe negative(-) batterystandoffsuppliesthe battery
ground input to the B- terminal for both the control and load circuits.
See Figure 3. Depressing the foot pedal in either Fwd or Rev will move the 5K Ohm (R1) potentiometer shaft off its centered balanced (neutral)
setting of approximately 2500 Ohms. With this pot shaft movement the pot’s resistance value changes which generates a variable voltage signal
(0-5 volts). These control board voltage input signals are what energizes the Fwd & Rev directional relays, which selects the motor polarity and
what also manages switches the battery voltage On and Off (**PWM) that varies the motor speed.
*KSI: Key Switch Input
**PWM:Pulse WidthModulation,alsocalled“chopping” isa techniquethat switchesbattery voltagetothemotorON andOFF veryquickly,thereby
controlling the speed of the motor.
DRIVE MODE SELECTION OPERATION OVERVIEW
TheA1 speed Controller allows operation in two distinct modes: mode 1 (M1) & mode 2 (M2).
Mode 1 (M1) is the transport speed range and is automatically selected when the scrub system is OFF (deck up). This allows maximum variable
vehicle speed operation.
Mode 2 (M2) is the reduced slower scrub speed range and is automatically selected when the scrub mode is ON (deck down).
The operator can over-ride the reduced M2 scrub speed by pressing the dash panel Speed Select Switch (L). This allows the operator to scrub at
the higher M1 transport speed. Note the Indicator Light (M) will be green when the faster transport speed is selected.
THE SPEED SELECTOR CIRCUIT INPUT
The main controller E1 will output a 30-31 volt (approximately) battery positive (B+) signal from the speed limit terminal J4-2 (Brn/Wht wire). This
positive signal connection delivers the required A1 speed control input to pin #8. The controller is now in scrub speed (mode 2) and the speed
controlmodeselectisswitchedON. PressingthedashpanelSpeedSelectSwitch(L)itsIndicatorLight(M)turnsON. Thisactionleavesthespeed
control input (pin #8) floating and actively switches it Off, 0 volts (pulling it to B-) changing the output to the transport speed (mode 1).
Note: The maximum machine drive wheel speed setting for the two drive modes 1 & 2 can be changed by using the Curtis handheld programmer.
Reference the Curtis programmer instructions found in the electrical system manual section to change speed settings from their original factory
specifications.
