FUNCTIONAL DESCRIPTION OF CONTROL SWITCHES:

The controls on the AquaRide™ / BRX 700 were designed with

one touch operation

in mind. For single pass extracting the user can

simply depress one switch and all systems on the machine will be ready to go. For most single-pass extracting operations, the operator should only need to use the top three switches on the control panel. These

are the Scrub System Off, Maintenance Extract Mode, and Restoration Extract Mode switches. In the maintenance mode the solution spray is directed at the scrub brush and the flow rate is reduced. The travel speed is limited to a medium speed. In the restoration mode the solution spray is directed at the carpet ahead of the scrub brush and the flow is at maximum. The travel speed is limited to a slow speed.

GENERAL FUNCTIONAL OVERVIEWGENERAL FUNCTIONAL OVERVIEW

GENERAL FUNCTIONAL OVERVIEW

See Figures 1 & 2. An 840-watt 1.1 HP (permanent magnet) 36V motor/gear transmission combination wheel unit (M3) is used to propel all machines. A Curtis model 1228 PMC solid state speed controller (A1) regulates (outputs) the variable speed Fwd/Rev wheel drive motor functions. 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 OVERVIEWDRIVE MOTOR SYSTEM CONTROLLER FUNCTION OVERVIEW

DRIVE MOTOR SYSTEM CONTROLLER FUNCTION OVERVIEW

See Figure 2. To make the A1 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 45 Amp supplies the positive high current (load) circuit input to the B+ controller terminal (Brn/Blk wire). The black wire from the negative (-) battery standoff supplies the 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 Width Modulation, also called “chopping” is a technique that switches battery voltage to the motor ON and OFF very quickly, thereby controlling the speed of the motor.

TION OVERVIEW

The following is a list of the speed control parameters that can be adjusted using a Curtis hand held programmer:

There are four programmable speed limits on the AquaRide. These are transport speed, fast maintenance speed, maintnance/fast restore speed, and restore speed. For the maintenance and restore modes, the fast speed is selected by pressing the

switch*switch*

switch* on the control panel.

For reference purposes, the speed control parameters below are followed by a number from 1 to 4. These are used to indicate which parameters apply to which operating mode of the machine.

(1) Transport mode [fastest] (scrub system off) (2) Fast Maintenance Mode (maintenance mode, speed select indicator = on) (3) Maintenance/Fast Restore Mode (maintenace mode, speed select indicator = off OR restore mode, speed select

indicator = on)

(4) Restore Mode [slowest] (restore mode, speed select indicator = off)

*Speed Select Switch:*Speed Select Switch:

*Speed Select Switch: This switch will allow the operator to select a faster travel speed while the scrub system is enabled thereby allowing extracting at a higher rate of speed. The speed select indicator will be green if a scrub mode has been selected and the faster scrub speed has been selected. It will be off otherwise.

SCRUB BRUSH SYSTEMSCRUB BRUSH SYSTEM

SCRUB BRUSH SYSTEM

FUNCTIONAL OVERVIEWFUNCTIONAL OVERVIEW

FUNCTIONAL OVERVIEW

• Cylindrical Brush System Overview• Cylindrical Brush System Overview

• Cylindrical Brush System Overview See Figure 6. The machines AquaRide SE and BRX 700 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. Note: The standard AquaRide PN56314008 uses only one brush motor and no debris sweep hopper.

• General Brush Overview• General Brush Overview

• General Brush Overview On all models the scrub deck platform is raised & lowered automatically by a vertically mounted electric lift actuator motor (M1). The

operation of the machine’s scrub functions are activated when the operator selects (presses) either the scrub maintenance or restoration (mode) panel buttons. The scrub brush pressure ranges (light through heavy) are programmable allowing the operator the choice to vary the scrubbing effort (pressure) for numerous carpet cleaning requirements. 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 combined membrane switch display panel and main control board E1. The major scrub system functions are…

• Scrub Brush Motor Run Function• Scrub Brush Motor Run Function

• Scrub Brush Motor Run Function To turn On (energize) the K1 brush motor solenoid either the scrub pressure maintenance or restoration buttons (location E1 panel)

must be pressed and the (foot activated) drive pedal moved off its neutral position triggering an output from the R1 directional throttle potentiometer. These two-operator functions deliver the required E1 control board and A1 speed control circuit inputs.

Detailed Explanation of the scrub motor function A closed E1 membrane panel switch input (either maintenance or restoration) enables the E1 microprocessor automatic functions for the brush lift,

brush solenoidbrush solenoid

brush solenoid, solution solenoid and vacuum solenoid. The next step is the movement of the foot pedal for the needed R1 throttle output to the A1 speed controller, which causes either FWD or REV motor action. At the moment of R1 throttle input the A1 controller closes an internal coil driver and outputs a POS. 36V signal from pin #6 (wire color Red/Blk) to the E1 J4-10 connection. This positive input signal causes the controller to output a NEG. 36V signal from J2 pin #1 (wire Wht/Red) and completes the K1 negative solenoid coil pulling in the high current contactor making the brush motor(s) turn on (run). Note: The positive K1 control circuit voltage is supplied by the E1 board’s J2 pin #8 wire (Wht/Brn).

• Scrub Brush Actuator Lift Motor Function• Scrub Brush Actuator Lift Motor Function

• Scrub Brush Actuator Lift Motor Function The control board outputs activate (raise and lower) the scrub-deck for installing, removing and controlling the scrub brushes’

selected pressure limits (current load). The negative (-) brush motor wire is specially designed so that it has a known (specified) resistance value. As brush motor current passes through the negative wire that is, in effect, a low value resistor, a small voltage drop is measured across it which is proportional to the motor current. This current measurement shunt circuit is made up of two small diameter sense wires (J4-12 Yel/Vio & J4-8 Blk) and are the inputs used by the control board to calculate the exact current level of the scrub brush motor(s). Any temperature change to the large (Neg.) motor wire affects its resistance so the circuit temperature is sensed by a thermistor (*) built into the control board. This allows the controller to provide a level of error correction for the temperature resistance changes. When the controller senses a current draw out of the desired range (selected pressure limit) it automatically turns on the M1 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.

• Low Voltage Cut-Out Function• Low Voltage Cut-Out Function

• Low Voltage Cut-Out Function The purpose of the low voltage cutout function is to help prolong battery life. The main control board E1 is programmed to monitor

the machine’s battery pack voltage to prevent over discharging of the batteries. The brush motors, brush lift actuator and solution solenoid valve will turn OFF automatically and cease to function when the batteries are discharged to the selected cutout level. The cutout level is adjustable between two settings. The standard battery type (wet cell) is 31.5 volts (1.75 volts per cell) and maintenance free battery (gel) is 33 volts (1.83 volts per cell). Note: See the Electrical System for instruction in selecting (setting) the two different thresholds.

* Thermistor: A special semiconductor resistor whose resistance value varies with temperature. Note: See the “Know Your Machine” section in this manual for a complete explanation for all scrub system operational modes.

TIONAL OVERVIEW OF THE SOLUTION PUMP & SOLENOID FUNCTIONS

Solution Delivery in the Auto ModeSolution Delivery in the Auto Mode

Solution Delivery in the Auto Mode Starts with the operator turning on the main power key switch then selecting either the maintenance or restoration mode switch.

Positive (+) battery circuit inputs and outputs

Inputs:

••

• A Solenoid circuit control coil (+) voltage input to control board E1 connector J2 pin #’s 6 & 7 (wire colors Brn/Yel).

••

• A closed S1 key switch supplies (+) input voltage to the E1 terminal J2 pin #10 (wire Brn). This powers up (turns on) the control board’s processing logic functions.

••

• A closed S2 operator safety seat switch enables allows the starting of the entire automatic machine scrubbing system functions. Its E1 terminal connection is J4 pin #11 (wire Orn).

Outputs:

••

• A control board E1 battery (+) voltage output from the solenoid accessory terminal connection J2 pin #8 Wht/Brn wire.

Negative (-) battery circuit inputs and outputs

Inputs:

••

• A main (-) battery ground input for the control board E1 terminal J4 pin#8 BLK wire. This supports the operation of the boards processing logic functions.

••

• Battery ground supply input for all the (control boards) negative output coil circuits. Its E1 terminal connection is J2 pin #5 (wire Blk).

Outputs:

••

• A battery ground output from the E1 control board terminal connector J2 pin #3 wire Vio/Blk for the L1 solenoid or J2 pin #4 wire Wht/Grn for the L2 solenoid. This controlled output turns on and off the L1 & L2 solenoid coils that stops and starts the solution flow through the valve body selected. This occurs every time the throttle is moved off its neutral setting into forward.

Solution Delivery in the Accessory ModeSolution Delivery in the Accessory Mode

Solution Delivery in the Accessory Mode Starts with the operator only having to turn on the main power key switch.

Positive (+) battery circuit inputs and outputs

Inputs:

••

• Accessory/solenoid circuit (+) voltage input to control board E1 connector J2 pin #’s 6 & 7 (wire colors Brn/Yel).

••

• A closed S1 key switch supplies (+) input voltage to the E1 terminal J2 pin #10 (wire Brn). This powers up (turns on) the control board’s processing logic functions.

Outputs:

••

• A control board E1 battery (+) voltage output from solenoid accessory terminal connection J2 pin #8 Wht/Brn wire. This feeds the pump pressure switch S3, which is built into the pump M4. The pressure switch is normally closed and will open when the head pressure reaches its cutout limit of 100 PSI. When the operator depresses the accessory wand trigger valve the trapped solution pressure drops below 100 PSI and the pump will run.

Negative (-) battery circuit inputs

••

• A main (-) battery ground input to the control board E1 terminal J4 pin #8 BLK wire. This completes the circuit support for the operation of the board’s processing logic functions.

••

• A direct battery ground input for completion of the M4 pump circuit

FUNCTIONAL OVERVIEWFUNCTIONAL OVERVIEW

FUNCTIONAL OVERVIEW

Vacuum / Recovery System GeneralVacuum / Recovery System General

Vacuum / Recovery System General To start the extraction wastewater is lifted out of the carpet pile by airflow created by two 3 stage 36V vacuum motors. See Figure

1. The wastewater and air enter at the two vacuum pick-up tools through their small narrow shoe openings that contact the carpet surface. The narrow shape of the shoe openings are designed to help speed up the airflow producing the needed suction to lift the waste water out of the carpet. Two smaller recovery hoses are connected together and direct the high-speed air/water movement to one large hose connected to the tank inlet. At this point the air and water enters the large flexible sealed recovery bladder, where the air slows down because of the increased (size) of the tank. With the decreased air speed the heavier water falls to the bottom of the recovery bladder. Then at the same time the airflow continues through shutoff float, vacuum motors and is exhausted out the bottom of the vacuum motor housing.

The vacuum system uses a shutoff float to prevent the tank from being overfilled and also stops any water from being sucked into the vacuum motors. This shut-off function works when the float ball reaches its tank full level and the ball becomes seated in the float housing. This action then causes a large restriction to the vacuum airflow and the main controller E1 senses a large electrical current load change (lower Amps) to the vacuum motors. This lower than normal vac circuit current load change tells the main controller that the recovery tank is full. This automatically shuts off the vacuum and scrub systems and displays “FULL” on the hourmeter/status display telling the operator that the recovery tank has become full.

VACUUM MOTOR CIRCUIT OVERVIEWVACUUM MOTOR CIRCUIT OVERVIEW

VACUUM MOTOR CIRCUIT OVERVIEW

There are two vacuum switch operator modes, Auto vacuum for machine transport extraction use and manual On/Off stationary optional accessory uses. Note: see the

Know Your Machine

section in this manual for a detailed description of the vacuum operation

modes.

Vacuum motor system function in the Auto Mode:Vacuum motor system function in the Auto Mode:

Vacuum motor system function in the Auto Mode: Starts with the operator turning on the main power key switch then selecting either the maintenance or restoration mode function switch.

Positive (+) battery circuit inputs and outputs

Inputs:

••

• See Figure 2. A Solenoid circuit control coil (+) voltage input to control board E1 connector J2 pin #’s 6 & 7 (wire colors Brn/Yel). Note: This input voltage supplies all the machine’s accessory and solenoid coil circuits (solution, vacuum, brush, headlight, warning beacon etc.).

••

• A closed S1 key switch supplies (+) input voltage to the E1 terminal J2 pin #10 (wire Brn). This powers up (turns on) the control board’s processing logic functions.

••

• A closed S2 operator safety seat switch enables the starting of the entire automatic machine scrubbing system functions. Its E1 terminal connection is J4 pin #11 (wire Orn).

Outputs:

••

• A control board E1 battery (+) voltage output from the solenoid accessory terminal connection J2 pin #8 Wht/Brn wire completes the positive voltage to the vacuum solenoid coil.

Negative (-) battery circuit inputs and outputs

Inputs:

••

• A main (-) battery ground input for the control board E1 terminal J4 pin #8 wire Blk. This supports the operation of the board’s processing logic functions with the above mentioned S1 (+) key switch input.

••

• A battery ground input for all the (E1 boards) negative solenoid coil output circuits. Its E1 terminal connection is J2 pin #5 (wire Blk).

Outputs:

••

• A battery ground output from the E1 control board terminal connector J2 pin #2 wire Gra/Blk. This control board output completes the K2 vacuum solenoid coil circuit (Pos. & Neg.) and pulls in the vacuum solenoid load contact K2 making the vacuum motor(s) M5 & M6 run. This occurs every time the throttle is moved off its neutral setting and the vacuum switch is on. Note: When the throttle is returned to neutral the vacuum will remain on for 10 seconds and the indicator light will flash green.

TROUBLESHOOTING GUIDETROUBLESHOOTING GUIDE

TROUBLESHOOTING GUIDE

When extracting the operator sees little or no (below normal) waste recovery water entering the recovery tank bladder, the vacuum system is not working properly. When a vacuum system performs poorly, it is usually because of one of the following problems:

Vacuum Leak(s)Vacuum Leak(s)

Vacuum Leak(s) – Air flowing into the vacuum system past a bad gasket or leaky hose, damaged tank, or a leaky drain hose cap. A vacuum leak below the water line will create turbulence in the recovery tank, causing water to enter the vacuum motor.

Restriction(s)Restriction(s)

Restriction(s) – Anything that blocks the flow of air through the system. Restrictions may also be caused by built-up debris in the pick-up tools, vacuum hoses, float cage or wherever the airflow is forced to make a sharp turn.

Both leaks and restrictions decrease the quantity of air flowing through the pick-up tools. The air that does go through the pickup tools moves with less pressure and volume, so it has less pick-up power.

Vacuum Electrical ComponentsVacuum Electrical Components

Vacuum Electrical Components – The vacuum systems major electrical components are monitored by the main controller to detect any system function failures (error codes). The system components covered are the vacuum motors and vacuum solenoid. Detected error codes from the main controller are displayed on the hour meter LED display as they occur. Note: Reference the

ACUUM / RECOVERY SYSTEM SERVICE MAINTENANCE CHECKLIST

Whenever there is a vacuum problem, it’s best to check over the entire system. Use the checklist below as a guide, to thoroughly check the vacuum system.

Clean built-up dirt from the inside of both vacuum pick-up (shoes) tools.

Inspect the vacuum motors duct (plenium housing) cover gaskets, clean foam air inlet filters and screens.

Inspect the hose between the pick-up tools and the recovery tank, rinse any built-up dirt from the hoses. Replace the hose(s) if it is kinked or damaged.

Inspect and make sure the gaskets on the recovery tank covers are sealing and not damaged.

Inspect and clean the vacuum motor float cage, float ball and shut-off seat.

Make sure that the recovery tank drain hose cap seals airtight.

TTERY MAINTENANCETTERY MAINTENANCE

TTERY MAINTENANCE

Proper maintenance of electric vehicle batteries can greatly extend their life. Well-maintained batteries may last up to 3 years, but failure after 1 year is common if maintenance has been poor.

There are 3 simple rules for good battery maintenance:

•

Maintain Proper Electrolyte Level (Weekly)Maintain Proper Electrolyte Level (Weekly)

Maintain Proper Electrolyte Level (Weekly) - Use distilled water in batteries whenever possible. If batteries are discharged, add just enough water to cover the plates in each cell. If batteries are fully charged, fill each cell to the bottom of the filler tube. Do not over-fill the batteries! Do not add acid to batteries!Do not over-fill the batteries! Do not add acid to batteries!

Do not over-fill the batteries! Do not add acid to batteries!Do not over-fill the batteries! Do not add acid to batteries!

Do not over-fill the batteries! Do not add acid to batteries!

•

Keep the Batteries Charged (Weekly) Keep the Batteries Charged (Weekly)

Keep the Batteries Charged (Weekly) - Batteries should be charged each time that a machine is used for more than 1 hour. Machine operators should open the battery compartment cover for charging, to avoid a concentrated build-up of hydrogen gas. Operators should follow the instructions provided with their specific battery charger, to determine how long the batteries should be charged. Even when a machine is stored, the batteries should be charged once a month to prevent the batteries from “sulfating”. Almost all battery caps are vented, so there’s no need to loosen or remove them for charging.

•

Keep the Batteries Clean (Monthly) Keep the Batteries Clean (Monthly)

Keep the Batteries Clean (Monthly) - Use a damp cloth to wipe dirt from the top of the batteries. Battery terminals must be clean and tight. If the tops of the batteries are wet after charging, the batteries have probably been over-filled or over-charged. Note: If there is acid on the batteries, wash the tops of the batteries with a solution of baking soda and water (2) tablespoons of baking soda to 1 quart of water.

TTERY TESTINGTTERY TESTING

TTERY TESTING

A battery problem is usually recognized by the machine operator, as a decrease in the machine’s running time. This condition is usually caused by one or more “dead cells” in the battery system that is, one or more cells that is putting out less voltage than the other cells.

Note:Note:

Note: Always charge batteries before testing. There are 2 ways to find a dead cell:

• Use a hydrometer to check the specific gravity (or “state of charge”) of the fluid in each cell. A dead cell is one that reads 50 points (or more) lower than the other cells.

• Use a volt meter to check the voltage of each battery with the scrub and drive motors running. The battery with the dead cell will read 1 or 2 volts lower than the other batteries in the system.

If the batteries in the machine are more than 1 year old, it’s usually best to replace the whole set, rather than replacing just one battery.

The chart below shows the approximate “percent charged” of an electric vehicle battery at various specific gravity values,

corrected to 80°F (26.7°C).

PROGRAMMER DIAGNOSTICSPROGRAMMER DIAGNOSTICS

PROGRAMMER DIAGNOSTICS

With a programmer, diagnostics and troubleshooting is more direct than with the LED alone. The programmer presents complete diagnostic information in plain language, no codes to decipher. Faults are displayed in the Diagnostic Menu, and the status of the controller inputs/outputs is displayed in the Test Menu.

The following 4-step process is generally used for diagnosing and troubleshooting an inoperative vehicle: (1) visually inspect the vehicle for obvious problems; (2) diagnose the problem, using the programmer; (3) test the circuitry with the programmer: and (4) correct the problem. Repeat the last three steps as necessary until the vehicle is operational.

Example: A vehicle that does not operate in “forward” is brought in for repair. 11

11

1 Examine the vehicle and its wiring for any obvious problems, such as broken wires or loose connections. 22

22

2 Connect the programmer, put it in diagnostic mode, and read the displayed fault information. In this example, the display shows

“No Faults Present”, indicating that the controller has not detected anything out of the norm.

33

3 Put the programmer in test mode, and observe the status of inputs and outputs in the forward direction. In this example, the

display shows that the forward input did not activate when “forward” was selected, which means the problem is either in the electronic throttle or the throttle wiring.

44

4 Check or replace the electronic throttle and wiring and repeat the test. If the programmer shows the forward switch closing

and the vehicle now drives normally, the problem has been corrected.

Refer to the Status Fault Codes

(Table 1)(Table 1)

(Table 1) for suggestions covering a wide range of possible faults.

DIAGNOSTIC HISTORYDIAGNOSTIC HISTORY

DIAGNOSTIC HISTORY

The handheld programmer can be used to access the controller’s diagnostic history file. Connect the programmer, press the MORE INFO key, and then while continuing to hold the MORE INFO key, press the DIAGNOSTICS key. The programmer will read out all the faults that the controller has experienced since the last time the diagnostic history file was cleared. The faults may be intermittent faults, faults caused by loose wires, or faults caused by operator errors. Faults such as HPD or over temperature may be caused by operator habits or by overloading.

After a problem has been diagnosed and corrected, clearing the diagnostic history file is advisable. This allows the controller to accumulate a new file of faults. By checking the new diagnostic history file at a later date, you can readily determine whether the problem was indeed completely fixed.

To clear the diagnostic history file, go to the Special Program Menu (by pressing and holding the MORE INFO key, and then pressing the PROGRAM key), scroll through the menu until “Clear Diagnostic History” is the top line in the display, and then press MORE INFO again. The programmer will prompt you to acknowledge or cancel.

SAFETY!SAFETY!

SAFETY!

The 1228 controller is inherently a high power device. When working around any battery powered vehicle, proper safety precautions should be taken. These include, but are not limited to: proper training, wearing eye protection, avoiding loose clothing and jewelry, and using insulated wrenches.

After installing a controller and before operating the vehicle, carefully complete the following checkout procedure. If you find a problem during the checkout, refer to the

DIAGNOSTICS

section of this chapter for further information.

The installation checkout can be conducted with or without the handheld programmer. The checkout procedure is easier with a programmer otherwise observe the Status LED for codes (located on operator panel wand indicator light). The part number of the handheld programmer is

5640944156409441

Put the vehicle up on blocks to get the drive wheel off the ground before beginning these tests. Turn the key switch off and make sure that the seat switch is open, and the throttle is in neutral. Do not stand, or allow anyone else to stand, directly in front of or behind the vehicle during the tests.

11

1 Remove electrical panel to access controller then observe LED status light on touch pad operator panel wand indicator light.

If a programmer is available, connect it to the programmer plug-in port.

22

2 Sit on the seat and turn the key switch on. The programmer should “power up” with an initial display. If neither happens, check

for continuity in the key switch circuit and controller ground.

33

3 If you are using a programmer, put it into the diagnostic mode by pressing the DIAGNOSTICS key. The display should indicate

“No Faults Found”. Note: Before pressing the diagnostics key, wait until model # screen appears, if the throttle is activated prior to this screen appearing the controller will shut down.

• If there is a problem, the LED will flash a diagnostic code and the programmer will display a diagnostic message. If you are

conducting the checkout without a programmer, look up the LED diagnostic code in the

DIAGNOSTICS

section of this chapter

(Table 1)(Table 1)

(Table 1).

• When the problem has been corrected, it may be necessary to cycle the key or seat switch to clear the fault code. 44

44

4 While sitting on the seat, operate the throttle. The motor should begin to turn in the selected direction. If it does not, verify the

wiring to the controller, and the motor. The motor should run proportionally faster with increasing throttle. If not, refer to the

DIAGNOSTICS

section of this chapter

(Table 1)(Table 1)

(Table 1).

55

5 If you are using a programmer, put it into the test mode by pressing the TEST key. Scroll down to observe the status of the forward,

reverse and brake switch. Cycle each switch in turn, observing the programmer. Each input should show the correct state on the programmer.

66

6 Take the vehicle off the blocks and drive it in an open area. It should have smooth acceleration and good top speed.

PROGRAMMING VEHICLE SPEED CHANGESPROGRAMMING VEHICLE SPEED CHANGES

PROGRAMMING VEHICLE SPEED CHANGES

The maximum high-speed M1 (transport) and maximum low speed M2 (scrub) can be changed electronically, using the handheld programmer. To change a parameter using the programmer, press the PROGRAM key, and scroll down the Program Menu until the desired parameter is the top line of the display. Press the appropriate CHANGE VALUE key (“up” or “down”) until the desired number is reached. The parameter is now set at the desired value. All programming occurs in real time. In other words, the parameters can be changed while the vehicle is in operation.

The upper and lower limits of parameters are set at the factory. Some parameters have dependencies on other parameters. When the programmer is being used to adjust a parameter and a limit is reached, the display will stop changing. To see why the display has stopped changing, press the MORE INFO key. If the limit is related to another parameter, that information will be displayed; changing the value of the related parameter may allow the original parameter to be adjusted further. Otherwise, the display simply says “Max Limit” or “Min Limit.”

Use of the programmer is described more fully in the

PROGRAMMER OPERATION

section of this chapter.

MAINTENANCE

There are no user-serviceable parts inside the Curtis PMC 1228 controller. No attempt should be made to open the controller. Opening the controller may damage it and will void the warranty.

However, it is recommended that the controller exterior be cleaned periodically, and if a handheld programmer is available, this periodic cleaning provides a good opportunity to check the controller’s diagnostic history file.

PART NUMBER 56409441 PART NUMBER 56409441

PART NUMBER 56409441 (Figure 6) allows you to program, test, and diagnose Curtis PMC 1228 controllers. The programmer is powered by the host 1228 controller, via a modular connector located in the front of the controller.

When the programmer is first plugged into the controller, wait until the programmer has acquired all the controller parameters. When this step has been completed, the programmer displays the controller’s model number, date of manufacture and software revision code. Following this initial display, the programmer displays a prompt for further instructions.

The programmer is operated via an 8-key keypad. Three keys select operating modes (Program, Test, Diagnostics), two scroll the display up and down, and two change the values of selected parameters. The eighth key, the MORE INFO key, is used to display further information about selected items within any of the three standard modes. In addition, when pressed together with the PROGRAM or the DIAGNOSTICS key, the MORE INFO key selects the Special Program mode or the Special Diagnostics mode.

The display window presents a 4-line LCD display. The display is visible even in bright sunlight. You can adjust the display contrast in the Special Program mode.

When one of the menu keys is pressed, the LED at the corner of the key lights up, identifying the mode of programmer operation. For example, if the TEST key is pressed, the LED at the corner of the key indicates that the programmer is now in the Test mode, and the Test Menu is displayed.

Four lines of a menu are displayed at a time. The item at the top of the display window is the selected item. To select an item, scroll within the menu until the desired item is positioned at the top of the display window. The selected item is always the top line. (In the Program mode, the selected item is highlighted by a flashing arrow). To modify a parameter or obtain more information about it, it must be scrolled to the top position in the display window.

To scroll up and down within a menu, use the two SCROLL DISPLAY arrow keys. The SCROLL DISPLAY arrow keys can be pressed repeatedly or be held down. When a key is held down, the scrolling speed increases the longer the key is held.

A small scroll bar at the left of the display window provides a rough indication of the position of the four displayed items within the entire menu. That is, when the bar is at the top of the window, the top of the menu is displayed. As you scroll through the menu, the bar moves downward. When the bar is at the very bottom of the window, you have reached the end of the menu. This sample display is from the Program Menu (Figure 7).

The two CHANGE VALUE arrow keys are used to increase or decrease the value of a selected menu item. Like the SCROLL DISPLAY arrow keys, the CHANGE VALUE arrow keys can be pressed repeatedly or be held down. The longer a key is held, the faster the parameter changes. This allows rapid changing of any parameter.

An LED on each CHANGE VALUE arrow key indicates whether the key is active and whether change is permissible. When the value of a parameter is being increased, the LED on the “up” CHANGE VALUE key is on until you reach the maximum value for that parameter. When the LED goes off, you cannot increase the value.

The MORE INFO key has three functions: (1) to display more information about the selected item, (2) to access the Special Program and Special Diagnostics modes (when used together with the PROGRAM and DIAGNOSTICS keys), and (3) to initiate certain commands (such as the Self Test).

“More information” is available in all of the programmer operating modes. After using the MORE INFO key to display additional information about the selected item, press the MORE INFO key again to return to the original list.

FUNCTIONAL OVERVIEW OF MAIN CONTROL BOARDFUNCTIONAL OVERVIEW OF MAIN CONTROL BOARD

FUNCTIONAL OVERVIEW OF MAIN CONTROL BOARD

The primary function of the main control board E1 is to position the scrubbing brush(s) with respect to the floor surface using a lift actuator motor to maintain the correct brush pressure and current draw of the brush motor(s). When either the maintenance or restoration scrub mode switch is depressed this will lower the scrub deck to the operating position and by activating the foot pedal start the brush motor. The controller is continuously monitoring the current to the brush motor and when it senses a current draw out of the desired range it automatically raises or lowers the brush deck by turning on the brush actuator motor. This process is repeated until the brush motor is shut off. The controller also manages the other supportive systems such as the extract deck in reverse lift, solution on/off, and vacuum motor. Note: See the Know Your Machine system in this manual for a complete explanation of the machine’s operation.

The secondary function of the main control is to detect any system failures and display an error code on the hour meter display or store it in the main control board’s recall memory mode. The error code(s) are used to help the serviceperson determine the fault and to quickly guide in repairing a specific system malfunction. Note: See the

If no over-current faults are present, the status display will show the battery voltage. This display is accurate to within +/- 0.15 volts. Therefore, the voltage displayed may not correlate precisely to a high-accuracy, calibrated voltmeter.

• An example of how 36.0 volts would be displayed is as follows:

• The display will show “3” followed by a brief blank period

• The display will show “6” followed by a brief blank period

• The display will show “_” followed by a brief blank period (serves as decimal point)

• The display will show “0” followed by a long blank period

• The above sequence will repeat

): This switch is used to control the output to the scrub deck lift actuator. Pressing and releasing this switch will cycle the actuator output through 4 states. These are: 1 - output off, direction = up 2 - output on, direction = down 3 - output off, direction = down 4 - output on, direction = up

When the output is in state 1, the actuator output is turned off. The maintenance mode indicator should be off. If the indicator is flashing green, this indicates that the control is sensing current flow through the actuator (shorted output driver, control error). If the maintenance mode switch was the last switch pressed, it is possible to momentarily activate the actuator output using the horn switch. This can be used to jog the actuator to allow precise positioning of the actuator. NOTE: the actuator can only move in this situation if it is not at its up limit.

When the output is in state 2, the actuator output is turned on. The maintenance mode indicator should be green or flashing green. The indicator will be a steady green if the control senses current flow through the actuator. It will flash green if no actuator current flow is sensed (actuator at limit, open circuit, open output driver). The horn switch has no effect in this state.

When the output is in state 3, the actuator output is turned off. The maintenance mode indicator should be off. If the indicator is flashing green, this indicates that the control is sensing current flow through the actuator (shorted output driver, control error). If the maintenance mode switch was the last switch pressed, it is possible to momentarily activate the actuator output using the horn switch. This can be used to jog the actuator to allow precise positioning of the actuator. NOTE: the actuator can only move in this situation if it is not at its down limit.

When the output is in state 4, the actuator output is turned on. The maintenance mode indicator should be green or flashing green. The indicator will be a steady green if the control senses current flow through the actuator.

The scrub brush pressure on the AquaRide can be adjusted to compensate for different brush and/or carpet types. The maintenance mode settings are 1 to 5 and the restore mode settings are 6 to 9. For each mode (maintenance or restore) the values represent a relative load on the motors with the small numbers (1 & 6) being the least load and the larger numbers (4 & 9) being the greatest load. A setting of 1 for the maintenance mode and 6 for the restore mode will provide an equal load for the motors. The same is true for settings 2 & 7, 3 & 8, and 4 & 9. NOTE: 4 & 5 provide the same load for the maintenance mode.
