KNOW YOUR MACHINE FUNCTIONAL DESCRIPTION OF CONTROL PANEL:

The controls on the Convertamatic 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 middle switches on the control panel. These are the Scrub System OFF and Scrub system ON switches.

Scrub OFF Switch (H) - 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 be raised to the up position

• The solution ﬂ ow will be stopped

• The ﬁ rst time that this switch is pressed, the vacuum 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 vacuum will shut of after a 10 second delay.

Scrub ON Switch (I) – If the scrub system is off, pressing this switch once will cause the following to occur:

• The scrub system will be enabled with the scrub pressure set to the regular setting and the scrub deck will be lowered. Note press twice for the heavy scrub pressure mode and hold this switch for 5 seconds to enter the extreme scrub mode.

• The vacuum system will be enabled.

• The solution system will be enabled.

• As soon as the throttle (operator drive paddle) is moved from the neutral position the scrub brushes will start turning and the vacuum will turn on. If the direction is forward the solution ﬂ ow will start. If the direction is reverse, the solution ﬂ ow will be stopped. If the scrub system is already enabled when this switch is pressed, the scrub pressure will increase to the heavy scrub mode. If the switch is held for 5 seconds the pressure will change to the extreme scrub mode. At the same time the panel display will show the correct changed scrub pressure setting.

Wand Switch (E) – This switch is used when an external vacuum/scrub wand is used. Pressing this switch will turn the vacuum on continuously without regard to the throttle position. If the scrub system was on it will be turned off. This includes turning off the scrub brushes and turning the solution ﬂ ow off (to the scrub deck). NOTE: automatic shutoff of the vacuum motor when the recovery tank is full is disabled when the wand is

enabled.

Key Switch (A) – Main power switch

Vacuum Switch (C) – This switch is used to turn the vacuum system on or off. Pressing this switch will alternate between on and off. The vacuum

will only turn on when the throttle is moved from the neutral position. It will remain on for 10 seconds after the throttle returns to neutral. The vacuum also has an automatic shutoff feature that will turn the vacuum and scrub systems off if the recovery tank becomes full.

Solution Switch (B) - This switch is used to turn the solution system on or off. Pressing this switch when the scrub system has been activated will alternate between on and off. The solution ﬂ ow will only turn on when the throttle is moved from the neutral position in the forward direction. The solution ﬂ ow will turn off if the throttle returns to neutral or is moved to reverse. Pressing this switch when the scrub system is off will momentarily turn the solution ﬂ ow on to allow pre-wetting of the scrub brushes.

Chemical Switch (AXP™ / ECO+Solution™ only) (F) – Pressing this switch will turn on or off the chemical option. See the main programming options in this manual to select (activate) the onboard chemical distribution system.

Extended Scrub (Recycle) Switch (G) - Pressing this switch will turn on or off the recycle option. See the main programming options in this manual to select (activate) the recycle option.

for 20 seconds. NOTE: This is to ﬂ ush any debris from the system. If you do not do this, the extended pump and(or) solenoid valve could become plugged up with debris.

Push and hold this switch for 3 seconds (the indicator (Q) will turn green) to initiate the purge function. The purge will run

KNOW YOUR MACHINE DESCRIPTION OF INDICATORS ON THE CONTROL PANEL:

In general, the following guidelines apply to the control panel indicators: A ﬂ ashing green 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 ﬂ ashing 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 ﬂ ash green indicating that the vacuum is still on but that it will be turning off after the delay period.

Scrub OFF Indicator (J):

• 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.

• This indicator will ﬂ ash red if there is a fault in the scrub system.

• This indicator will be off if the scrub system has been activated.

Regular Scrub ON Indicator (K):

• This indicator will be yellow if the scrub system is enabled in “Regular” scrub mode but the drive paddle is in neutral.

• This indicator will be green if the scrub system has been turned on in “Regular” scrub mode and the machine is moving in either direction.

• This indicator will be off if the scrub system has been turned OFF.

Heavy Scrub ON Indicator (L):

• This indicator will be yellow if the scrub system is enabled in “Heavy” scrub mode but the drive paddle is in neutral.

• This indicator will be green if the scrub system has been turned on in “Heavy” scrub mode and the machine is moving in either direction.

• This indicator will be off if the scrub system has been turned OFF.

SOLUTION SYSTEM FUNCTIONAL OVERVIEW

See Figure 1. The Warrior™ / BA 755 series models have a solution tank ﬁ ll capacity of 30 gallons (113.5 Liters). All models use one right rear tank ﬁ ll opening,

which offers ease of ﬁ lling. Plumbed into the manual solution shut off valve outlet is a serviceable Solution Filter (C), to keep debris from entering the solenoid valve (all models) and solution pump (AXP™ / ECO+Solution™ only). Also ﬁ tted to the tank is a ﬂ exible Clear Hose (B) used to indicate the solution level and to drain the tank for system maintenance.

The solution system uses an electrical Solenoid Valve (L1) which stops and starts the solution ﬂ ow to the scrub brushes. The M7 water pump (A) located on the machine chassis controls the needed ﬂ ow volume demand to the scrub brushes (AXP™ / ECO+Solution™ only). See Electrical Diagram Figure 2. The electrical circuit that turns on (energizes) the solenoid coil and water pump is activated through the (A1) control panel’s solution switch button input and the FWD / REV (A2) Speed Controller voltage output signals. Note: See the Know Your Machine section in this manual for a complete explanation of the solution operation modes.

During normal machine scrubbing the solution system’s Auto Mode is selected and works in conjunction with the wheel drive speed controller and the (A1) main controller’s scrub system outputs to turn On & Off the Solenoid Valve (L1) and Pump (A). The solution will ﬂ ow to the scrub brushes when the scrub deck is lowered and the handle drive paddle (box) is pushed Fwd. Note: When the solution On/Off button is turned Off, no ﬂ ow can occur while the machine scrub deck is down and the drive paddle activated.

SOLUTION SYSTEM CIRCUIT OVERVIEW SOLUTION AUTO MODE (SOLENOID VALVE CIRCUIT)

APPLIES TO AXP™ / ECO+SOLUTION™ MODELS See Figure 2. + (Positive) circuit input starts with:

• A closed S3 key switch will direct the needed positive voltage (BRN wires) to the L1 solenoid coil and A1 control board terminal #J1-13.

- (Negative) circuit input starts with:

• A battery negative ground input at the A1 control board terminal #B2 (J1-9)

• The A1 control board solution button enabled.

• A negative voltage output from the A2 speed controller’s (pin #6) Red/Blk wire to the A1 control board Red/Blk wire (terminal J1-5). Note: The A2 speed controls brake output (pin #6) occurs whenever the R1 direction throttle pot is moved off its neutral setting.

• A negative voltage output from the A1 board’s terminal J1-11 Red/Grn wire is direct to the L1 solenoid coil turning it on to allow ﬂ ow through the valve body.

CIRCUIT OVERVIEW SOLUTION AUTO MODE (SOLUTION PUMP CIRCUIT)

APPLIES TO AXP™ / ECO+SOLUTION™ MODELS See Figure 2. + (Positive) circuit input starts with:

• With the batteries connected the needed positive voltage (Red wires) to the M7 Solution Pump.

- (Negative) circuit input starts with:

• A battery negative ground input at the A1 control board terminal #B4 (J2-6)

• The A1 control board solution button enabled.

• A negative voltage output from the A1 board’s terminal J1-8 Grn/Blk wire is direct to the M7 Solution Pump turning it on to allow ﬂ ow to the L1 Water Valve Solenoid. NOTE: The solution pump’s output volume is controlled by the A1 board’s programmable capability and changes the pulsing of the negative battery connection to the pump. This circuit turns the pump on and off by supplying different reduced voltage values which manages the (3) different working ﬂ ow volumes.

CIRCUIT OVERVIEW SOLUTION AUTO MODE (SOLENOID VALVE CIRCUIT)

APPLIES TO STANDARD (NON AXP™ / ECO+SOLUTION™) MODELS

• NOTE: The standard machines do not use a solution pump. The (3) standard solution ﬂ ow volumes are managed by the A1 control board’s negative voltage output from the terminal J1-11 Red/Grn wire. This circuit turns on and off thus opening and closing the L1 solenoid which manages the (3) distinctive solution ﬂ ow rates by gravity feed only.

SCRUB SYSTEM FUNCTIONAL OVERVIEW

• Disk Brush System Overview

See Figure 2. The disk models use a disk type scrub system powered by (2) 3/4 hp motor gearbox assemblies.

• Cylindrical Brush System Overview

See Figure 4. The cylindrical models use two cylindrical brushes that counter rotate to sweep up light debris and scrub at the same time. Each scrub brush is

powered on opposing ends by 3/4 HP permanent magnet motors attached to separate poly-V belt/pulley drives.

• General Brush Overview

Note: Recovery Tank Full switch must be closed (Tank empty). On all models the scrub deck platform is raised & lowered automatically by a vertically mounted

electric lift actuator motor. The operation of the machine’s scrub functions are activated when the operator selects (presses) the scrub on (mode) panel button. The scrub pad or brush pressure ranges (1-3) are selectable allowing the operator the choice to vary the scrubbing effort (pressure) while operating the machine. Note: See the Main Control Board Special Program Options section in this manual for more detailed operation and instructions to change scrub pressure settings.

See Figure 1. The machine’s main scrub system input and output operating functions are regulated (managed) by the display panel and combined main control board A1. The major scrub system functions are…

• M2 / M3 - Scrub Brush Motor Run Function

Circuit Overview Scrub Brush Motor

+ (Positive) Circuit input starts with:

• A closed S3 key switch supplies the needed positive voltage to the K1 brush solenoid coil and the A1 control board #J1-13 (Brn wire). Note: The A1 control board scrub-on button must also be depressed (enabled). This operator command lowers the brush deck. Once the K1 load is closed the needed Positive voltage is supplied to the motors M2 and M3.from battery Pos.

- (Negative) Circuit input starts with:

• A battery negative ground input at the A1 control board terminals B2 (J1-9) Blk and B1 (J1-7) Blk.

• Note: The A1 control board scrub-on button must also be depressed (enabled).

• A negative voltage output from the A2 speed controller’s Neg. (pin #6) Red/Blk wire to the A1 control board Red/Blk wire (terminal J1-5). Note: The A2 speed control brake output (neg.) (pin #6) occurs whenever the R1 direction throttle pot is moved off its neutral setting.

• A negative voltage output from the A1 board’s terminal (J1-14) Vio/Blk wire completes the K1 solenoid coil circuit (Pos. & Neg.) and pulls in the load contact making the brush motors run.

The Neg. M2 and M3 load voltage is supplied from the battery Neg.

• M5 - Scrub Brush Actuator Lift Motor Function

The A1 control board outputs a controlled motor voltage polarity change (wires J2-1 and J2-8) that raises and lowers the scrub-deck for installing, removing and controlling the scrub brushes’ selected current load. The large BLK negative (-) scrub brush motor wire is specially designed so that it has a known (speciﬁ ed) resistance value. As brush motor current passes through the negative wire that is, in effect, a low value resistor, a small voltage drop is developed across it which is proportional to the motor current. This voltage change is inputted to the A1 control board at J2-5 and J1-7(sense wires WHT/GRA & BLK). Any surrounding temperature change in this large Neg. motor wire affects its resistance so the temperature is sensed by a thermistor (*) built into the control board A1. This allows the controller to provide error correction for the temperature resistance changes. When the controller senses a current draw out of the desired range it automatically turns on the M5 actuator motor to raise or lower the scrub deck. This process is on going in maintaining the operator’s selected scrub motor current load setting to sustain the desired brush working pressure.

• Scrub System Low Voltage Cut-Out Function

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 1.72 volts per cell and alternate setting (gel/maintenance free) is 1.81 volts per cell. Note: See the battery system section for instructions for selecting (setting) the two different thresholds.

SPECIAL SCRUB SYSTEM FUNCTIONS

• Scrub Brush Removal Function (Disc only)

For removal of the scrub brushes automatically, the scrub deck must be in the up position and the drive system in neutral. To remove the scrub brushes simply depress the control panel scrub-off button (H) for 2-3 seconds. The A1 control board will momentarily run the brush motors and then stop them quickly, where the brushes inertia causes the brushes to easily spin off of the scrub brush motors drive caps.

SCRUB SYSTEM

• Scrub Brush Removal Function (Continued / Disc only)

• Control and Load circuit detail.

A closed S3 key switch supplies the needed positive voltage to the K1 brush solenoid coil, A1 control board (J1-13) Brn wire and K3 brush remove coil relay

(Part of A1 Control Board).

- The brush remove circuit sequence starts when the operator depresses the control panel scrub off button (H) for 2-3 seconds activating the A1 board’s brush remove function. This triggers (starts) an internal timer relay closing the K1 coil ground circuit, pin (J1-14) Vio/Blk wire turning on momentarily the brush solenoid to run the brush motors.

- Simultaneously with the K1 coil being turned on the same input command closes the K3 coil (Part of A1 Control Board) turning it ON.

- This pulls in the K3 load contacts (Part of A1 Control Board) connecting it to the battery ground through the A1 Brush Remove circuit N.O. Blk wire and Common Blu/Wht wire to K1 Load Contactor N.C

- The next step is the board timer turning off the K1 brush solenoid and connecting the normally Pos. motor load circuit to a battery ground, sending a neg. voltage from the K3 Relay (Part of A1 Control Board) though the Blu/Wht N.O. wire. When K1 is de-energized the neg. voltage from the K3 relay is connected to the Brush Motors Positive Wht. wires through a Red/Wht jumper wire connected to the K1 N.C.

- With two battery ground inputs at the brush motors this circuit causes a short to ground and the motors stop abruptly. The built up brushes inertia easily spins the brushes off the motors drive disc lugs.
