KNOW YOUR MACHINE

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 fl ow 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 fl ow is at maximum. The travel speed is limited to a slow speed.

Scrub System Off Switch (B) - Pressing this switch when the scrub system is active will cause the following to occur:

• The scrub brush(s) will turn off and the scrub deck will raise to the up position

• The vacuum will shut off after a 10 second delay

• The travel speed limit will return to the transport speed setting

Maintenance Extract Mode 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 system confi gured for maintenance mode and the scrub deck will be lowered

• The vacuum system will be enabled

• The solution system will be enabled for maintenance mode

• The travel speed will be limited to the maintenance mode speed setting

• As soon as the throttle is moved from the neutral position the scrub brush(s) 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. It is possible to program the control to automatically raise the scrub deck in reverse. Refer to the Electrical System “Main Control Board Special Program Options” for details.

If the restoration mode is selected, pressing this switch will select the maintenance mode. If the maintenance mode is already selected, pressing this switch will have no effect.

Restoration Extract Mode 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 system confi gured for restoration mode and the scrub deck will be lowered

• The vacuum system will be enabled

• The solution system will be enabled for restoration mode

• The travel speed will be limited to the restoration mode speed setting

• As soon as the throttle is moved from the neutral position the scrub brush(s) 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. It is possible to program the control to automatically raise the scrub deck in reverse. Refer to the Electrical System “Main Control Board Special Program Options” for details.

If the maintenance mode is selected, pressing this switch will select the restoration mode. If the restoration mode is already selected, pressing this switch will have no effect.

FUNCTIONAL DESCRIPTION OF CONTROL SWITCHES (CONTINUED)

Accessory Vacuum ON/OFF Switch (I) - This switch is used when an external scrub wand is used. Pressing this switch will turn the vacuum on continuously without regard to the throttle position. It will also enable the solution pump. If the scrub system was on it will be turned off. This includes turning off the scrub brush(s) and raising the scrub deck and turning the solution fl ow to the scrub deck off. NOTE: Automatic shutoff of the vacuum

motor when the recovery bladder is full is disabled when the wand is enabled. The fl oat in the recovery bladder will still prevent water from entering the vacuum motor, but the motor will not shut off.

Key Switch / Main Power (J) – Main Power Switch.

Speed Select Switch (L) – 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. This option can be disabled if desired. See the Electrical System “Main Control Board Special Program Options” for details.

The transport, maintenance mode, and restoration mode speed limits can be programmed using a Curtis handheld programmer. Refer to the Electrical

System “Main Control Board Special Program Options” for details.

Horn Switch (N) – This switch will sound the horn as long as the switch is held.

The horn also functions as an automatic back-up alarm when the throttle is moved to the reverse position. The volume of the back-up alarm is programmable. It can also be programmed to provide an annunciation feature that will sound whenever the throttle is in the forward position. See the Electrical System “Main Control Board Special Program Options” for details.

Vacuum Switch (O) - 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 bladder becomes full. If this occurs, the status display will show the word “FULL”. This feature can be disabled if desired. The shutoff threshold can also be adjusted if necessary. See the Electrical System “Main Control Board Special Program Options” for details.

Solution Switch (R) - 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.

DESCRIPTION OF THE BATTERY CONDITION INDICATORS

The battery condition indicator (K) consists of three lights; a green (K3), a yellow (K2) and a red (K1). A fully charged battery pack will measure above 37.6 volts with no load applied (2.09 volts per cell). The AquaRide

/ BRX 700 is equipped with a low voltage cutout feature that will turn the scrub system off when the batteries are discharged to their minimum level. There are two different cutout levels to accommodate different battery types. See the Electrical System “Main Control Board Special Program Options” for details. The voltage levels for the various indications are as follows (the voltages shown represent the voltage under load):

Green 34.00+ 34.50+

Green & Yellow 33.00-33.99 34.00-34.49

Yellow & Red 31.50-31.99 33.00-33.49

Flashing Red/Cutoff <31.00 <32.50

NOTE: Refer to service manual for selection of alternate cut-off level. Once the low voltage cutout level has been reached (fl ashing red indicator) the batteries must be FULLY recharged (37.6V) to reset the battery condition indicator. The scrub system will not function until the indicator has been reset.

DESCRIPTION OF ADDITIONAL HOURMETER / STATUS DISPLAY FUNCTIONS

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:

WHEEL DRIVE SYSTEM

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 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.

DRIVE MODE SELECTION OPERATION 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 speed select 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)

POTENTIOMETER INSTALLATION AND ADJUSTMENT

WARNING!

The adjustment of the potentiometer is to set the drive pedal for a neutral drive motor operation. If the pot is not adjusted properly, the machine will creep in either FWD or REV.

1 See Figure 9. Install the pot into the Mount Housing (AK) and tighten the attachment nut.

2 Connect together loosely both the Link Rod (AE) to the Pedal (AF), and the Throttle Lever (AJ) to the potentiometer input shaft. Then tighten only the Link Rod (AE) pedal mounting Hardware (AG). Note: Check the movement of the Foot Pedal (AF) it must move freely in both Fwd and

Rev.

3 See Figure 9 inset. Attach test leads from a volt/ohm meter (set meter on 0x100 scale) to the YEL and VIO wire connection points on the potentiometer to check it’s total resistance (example 4800 Ohms).

4 Next connect the ohmmeter test leads to the GRA and VIO potentiometer connection points. Then using a small screwdriver, turn the shaft end on the pot to half the total resistance previously measured. Example: 4800 Ohms divided by 2 = 2400 Ohms. Then without turning the shaft, tighten the Screw (AI) and Nut (AH) to secure the setting at the Throttle Lever (AJ).

5 Follow steps 1-2 in reverse order (see Potentiometer Removal steps) to fi nish the installation. Then test-drive the machine for proper speed and

FWD/REV directional control.

DRIVE PEDAL NEUTRAL ADJUSTMENT & PEDAL REPLACEMENT

If the drive pedal has been removed or replaced, the neutral position for the pedal will have to be set. Follow the steps below to accomplish this.

WARNING!

Disconnect the machine’s battery pack connector (13) before servicing.

Note: See Figures 9 & 10. Before making any adjustments, inspect the Torsion Spring (AL) for defects and the correct positions of both spring ends (repair or replace).

To Adjust Pedal Spring the needed pre-load pressure to eliminate excessive pedal free-play and a balanced spring rate to return the pedal to a centered (neutral) position.

2 Push the screw back into the pedal frame slot to increase spring tension and eliminate pedal free play. Then tighten the screw & nut being careful not to pull on the linkage connection to the pot shaft and disturb (move) its neutral setting.

To Replace Pedal or Spring

3 Position the torsion spring ends (A & B) as shown. This is with the Bushing (AO) and Screw (AM) not installed.

4 Place the bushing inside the pedal channel pilot it into position using a scratch awl or a pin punch.

5 Then pivot (press) the pedal and insert the screw from the opposite side pushing the guide tool out.

6 Use a screwdriver to tap and pry the bushing back in the pedal slot to increase spring tension

7 Work the bushing back & forth on both sides of the pedal to obtain equal spacing. Then tighten the screw and nut.

8 A correctly adjusted drive pedal will have minimal amount of free-play when selecting a drive direction.

9 Reconnect the batteries and test the machine to make sure it does not “creep” forward or reverse when the pedal returns to neutral.

10 Service Tip: Also confi rm the Hourmeter/Status Display (G) is free of the error code 03 (drive system fault). If error 03 is shown the throttle is not set properly for the potentiometer and or drive pedal neutral position. Check both again and readjust.

SCRUB BRUSH SYSTEM

FUNCTIONAL 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.

• 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

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 twooperator 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 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

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 (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 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

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.

SOLUTION SYSTEM

FUNCTIONAL OVERVIEW

See Figure 1. Two molded plastic (polyethylene) tanks rear recovery and the main body structure store the machine’s extraction solution. Total machine solution capacity is 45gallons (170 L). Plumbed into the solution shut off Valve (C) outlet is a serviceable spin off Filter Housing Assembly

(D) that keeps debris from entering the Solution Pump (E) and solenoid valves (L1 & L2). Also fi tted between the storage tanks is a short fl exible

Drain Hose (F) to drain both tanks for system maintenance.

The electrical circuit that turns on (energizes) the solenoid coils is activated through the combined operator panel buttons and main controller assembly

E1. Note: See the Know Your Machine section in this manual for a detailed explanation of the complete solution operation modes. The two electrical solenoid valves L1 maintenance and L2 restoration control (start and stop) the two specifi c defi ned solution nozzle outputs. The pump’s fl ow volume is directed through one or the other operator selected (turned on) solenoid valve by hoses to the two separate brush nozzles A & B. Nozzle (A) directs the solution spray pattern onto the scrub brush when in the maintenance extraction mode (minimum fl ow). Nozzle (B) directs the solution in front of the scrub brush when in the restoration mode (maximum fl ow).

RECOVERY SYSTEM

FUNCTIONAL OVERVIEW

Vacuum / Recovery System General

To start the extraction wastewater is lifted out of the carpet pile by airfl ow 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 airfl ow 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 fl exible 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 airfl ow continues through shutoff fl oat, vacuum motors and is exhausted out the bottom of the vacuum motor housing.

The vacuum system uses a shutoff fl oat to prevent the tank from being overfi lled and also stops any water from being sucked into the vacuum motors. This shut-off function works when the fl oat ball reaches its tank full level and the ball becomes seated in the fl oat housing. This action then causes a large restriction to the vacuum airfl ow 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 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:

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 fl ash green.

RECOVERY SYSTEM

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) – Air fl owing 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) – Anything that blocks the fl ow of air through the system. Restrictions may also be caused by built-up debris in the pick-up tools, vacuum hoses, fl oat cage or wherever the airfl ow is forced to make a sharp turn.

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

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 Main Control Board Troubleshooting Guide in the

Electrical System of this manual for specifi c fault descriptions and service repair actions.

VACUUM / 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 fi lters 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 fl oat cage, fl oat ball and shut-off seat.

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

MAINTENANCE OF VACUUM FILTER AND FLOAT CAGE

See Figure 3. To inspect and clean the vacuum motor foam fi lter just lift open the tethered Vac Duct Cover (A). Remove the fi lter by pulling it out from the housing opening. Clean the fi lter by vacuum or washing it out in warm water. Note: The fi lter must be completely dry before reinstalling.

To inspect the vacuum shut off fl oat just open the right rear recovery tank cover to access the fl oat cage assembly (back center in recovery tank).

The cage openings must be kept free of any debris that can restrict maximum airfl ow. To keep it clean, wipe off with a rag regularly or remove and fl ush with water. The cage is a two piece design and can be snapped apart to separate. Note: Another method of accessing the cage fl oat for servicing is to remove the (6) (B) Screws and remove the vacuum duct housing (C) from the recovery tank top opening.

RECOVERY TANK BLADDER INSTALLATION

1 Mix a one-quart volume of water and soap solution in a small spray bottle then spray the insides of the recovery tank and the outside of the bladder just before installing. This needs to be done to help the bladder slide easily when positioning it in place. Note: Do not use any siliconebased products that will be in contact with the bladder, damage to the bladder will result.

2 Install the special rope and pulling bar inside the bladder as shown. Service Tip: Figure 5 shows the dimensions for building the pulling tool needed to install the drain fi tting through the bottom tank mounting hole.

3 Next feed the end of the rope from the drain fi tting of the bladder through the bottom of the tank hole to the outside.

4 Carefully push the bladder down into the recovery tank with the needed assistance of pulling on the rope.

5 Working through the tank drain outlet opening pull the rope and pry the bladder tube fi tting down where it is partially visible.

6 Spray additional soap solution through drain hole and hold the rope fi rmly while prying down on the fi tting using a screwdriver to keep the fi tting from pulling away from the tank hole (use caution to not damage the bladder).

7 Remove the screwdriver and quickly slide in a piece of a rounded end steel shafting (approximately 3/4” in Diameter and 18” in length, a large auto mechanics breaker bar works well) into the drain opening.

8 Pull down on the rope and quickly pull up on the lever turning and drawing the drain tube into the tank hole opening. Next pull out from the top bladder opening the drain tube pulling tool by its free rope end.

9 Reinstall all of the previously removed plumbing fi ttings, support straps, hardware and hoses. Service Tip: To easily install the plastic drain hose Bushing (U) onto the aluminum drain tube drop the bushing into a small cup of warm water to soften.

BATTERY SPECIFICATIONS

- Use a combination of multiple 2-volt cell units (wired in series) to construct a 36 Volt DC battery pack system.

- Nilfi sk-Advance recommended battery pack capacity is a 238 or 305 AH @ 20 Hour Rate deep cycle battery system (six 6V-batteries). Note: The battery pack must fi t the battery compartment size listed in Specifi cations.

BATTERY CHARGER SPECIFICATIONS

- Use a 36 Volt DC output charger matching the DC battery pack voltage and the input AC line voltage supply being used.

- Always when selecting a battery charger follow the recommendation of the battery supplier to match the proper charger DC output amperage to the amp/hour rating batteries being installed. This will prevent the battery pack from being over or under charged.

- The recommended 238 AH battery should be matched to a 36V, 20 Amp charger.

- The recommended 305 AH battery should be matched to a 36V, 25 Amp charger.

INSTALL THE BATTERIES

WARNING!

Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin or eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery caps. This gas can be ignited by any electrical arc, spark or fl ame.

When Servicing Batteries...

Remove all jewelry.

Do not smoke.

Wear chemical goggles, rubber gloves and a protective apron.

Work in a well-ventilated area.

Do not allow tools to touch more than one battery terminal at a time.

CAUTION!

Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Batteries should be installed by Nilfi sk-Advance or by a qualifi ed electrician.

FIGURE 1

1 Remove the batteries from their shipping crate and carefully inspect them for cracks or other damage. If damage is evident, contact the carrier that delivered them or the battery manufacturer to fi le a damage claim.

2 Turn the Master Key Switch (J) OFF (O) and remove the key.

3 To access the battery compartment tip the operator’s seat forward and set the prop rod. Remove the battery cables from inside the battery compartment.

4 Your machine comes from the factory with enough battery cables to install six (6 volt), 305 Amp hour batteries. Using two people and an appropriate lifting strap, carefully lift* the batteries into the compartment tray exactly as shown on machine decal (Figure 1).

5 The terminals on the battery cables are marked “+” for positive and “-“ for negative. Install the battery cables as shown, with the terminals marked “+” on the positive battery terminals and the terminals marked

“-“ on the negative terminals. Position the cables so the battery caps can be easily removed for battery service.

6 Carefully tighten the nut in each battery terminal until the terminal will not turn on the battery post. Then tighten the nut half an additional turn. Do not over-tighten the terminals, or they will be very diffi cult to remove for future service.

7 Coat the terminals and posts with spray-on battery terminal coating

(available at most auto parts stores).

8 Put one of the black rubber boots over each of the terminals and retain with supplied tie straps.

9 Connect the battery pack connector to the Machine Battery Connector (22) and close the operator’s seat platform.

DESCRIPTION OF THE BATTERY LOW VOLTAGE CUTOUT FEATURE

All models discussed in this manual are equipped with a low voltage cutout feature to prevent over-discharging of the batteries. When a machine’s battery pack voltage falls below specifi cally defi ned thresholds (voltage settings) the scrub system is automatically shut down. The cutout level is adjustable. The standard lead acid battery (wet cell) setting is 1.72V per cell and alternate maintenance free battery (gel cell) setting is 1.81V per cell. The standard setting is factory selected and should be used unless the battery manufacturer specifi es the higher cutout voltage.

Special Service Note: On all machines (36V) a minimum recharge voltage of 2.09 volts per cell must be reached to allow the scrub brush and solution system to (reset) function again. The 36V-battery pack must increase to a 37.6-volt minimum.

DESCRIPTION OF THE BATTERY CONDITION INDICATORS

The Battery Condition Indicator (K) will give an indication of the state of charge of the batteries. The battery condition indicator will retain the state-of-charge even if the key has been turned off. The state-of-charge indication is reset to full charge when the batteries have been recharged.

It is also possible to choose between two different low voltage thresholds depending on whether maintenance free or standard batteries are being used (have qualifi ed service engineer perform this selection*). NOTE: The following percentages are based on useable battery capacity not total battery capacity. Therefore, 100% discharge = 80% of total battery capacity for standard wet cell batteries or 70% of total battery capacity for maintenance free batteries.

ELECTRICAL SYSTEM

BATTERY 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) - 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, fi ll each cell to the bottom of the fi ller tube. Do not over-fi ll the batteries!

Do not add acid to batteries!

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 specifi c 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) - 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-fi lled 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.

BATTERY 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: Always charge batteries before testing.

There are 2 ways to fi nd a dead cell:

• Use a hydrometer to check the specifi c gravity (or “state of charge”) of the fl uid 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 specifi c gravity values, corrected to 80°F

(26.7°C).

General Instructions for All Actuator Motors

1 See Figure 2. This shows the special actuator power cord adapter (PN 56407502) that is needed to connect the machine’s battery pack and actuator motor for setting the drive nut limit settings.

2 Open the machine battery compartment and disconnect the battery connector. The battery pack is needed to power the lift actuator motor to properly set the IN & OUT limit switches.

3 Connect the actuator motor to be tested to the power cord adapter end. Then connect the alligator clips from the cord adapter (red clip to the positive and black to negative) to battery connector or battery posts. The rocker switch is used to change the motor rotation in setting the correct drive nut dimension.

FIGURE 2

Instructions for Scrub Brush Lift Actuator Drive Nut Adjustment

1 See Figure 3 and 4. On a new scrub lift actuator motor remove (spin-off) the Drive Nut (A) fi rst slide on the short compression Spring (B) onto the actuator (lead screw) shaft. Next reinstall the plastic drive nut as shown (with the nut pin pocket away from the motor). Then fi nish assembly of remaining parts (long compression spring, Spring Housing (C) and mounting hardware).

2 Hold onto the spring housing assembly and press the rocker switch to run the drive motor and retract the spring housing towards the motor housing (its IN limit).

3 Measure the position of the spring housing assembly on the actuator shaft. Manually turn the spring housing assembly to the appropriate IN position shown in the chart above.

4 Hold the spring housing assembly then press the adapter cord rocker switch to run the drive motor to the OUT position (wait until the motor stops).

5 Measure the position of the spring housing assembly on the shaft and compare the measurement with the OUT position shown in the chart.

6 When the measurement doesn’t match the dimension shown in the chart it is necessary to remove the Adjuster Cover (D) and adjust the OUT position.

7 To increase the travel of the spring housing assembly, turn the adjuster clockwise. To decrease the travel of the assembly, turn the adjuster counter clockwise.

NOTE: Use a 1/2” (13mm) socket to turn the adjuster. Each click of the adjuster will change the spring housing assembly travel 1/16 inch

(1.6mm).

8 After each adjustment, hold the spring housing assembly, run the actuator IN & OUT and check both dimensions. After checking that the spring housing limits are set correctly replace the adjuster cover. Service Tip Note: Use the above power cord adapter to help position the spring housing assembly (in or out) for ease in actuator motor installations.

9 After adjusting the actuator spring housing dimensions, follow the Scrub Brush Lift Actuator Removal manual section to reassemble.

Service Tip: See Figure 4. Note the correct orientation of the Spring Housing (C) when installing the complete motor assembly and also run the spring housing assembly to the IN (retracted) position for machine installation.

CURTIS CONTROLLER DIAGNOSTICS

Diagnostics Method A: Uses the machine’s control panel hourmeter display and wand switch indicator.

FUNCTION OF THE SPEED CONTROLLER STATUS LIGHT AND DISPLAY

The Curtis 1228 speed control will output a fault code if there is a problem associated with the speed control and wheel drive system. See Figure

5. If a speed control fault occurs, the Hourmeter/Status display (G) will indicate “E03”. When the E03 is being displayed and detects a fault the

Green Indicator (H) normally the accessory wand indicator light will fl ash a special error code sequence until the fault is corrected. See “Table 1” for a description of the fault indications. Service Note: Instructions on how to read the error code status light. Example, OO O = two light fl ashes, a short pause. One fl ash, long pause and the code will be repeated. This indicates a fault code 2,1.

FIGURE 5

Diagnostics Method B: Uses the optional hand held Curtis programmer model 1307.

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.

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

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.

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.

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) for suggestions covering a wide range of possible faults.

DIAGNOSTIC HISTORY

The handheld programmer can be used to access the controller’s diagnostic history fi le. 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 fi le 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 fi le is advisable. This allows the controller to accumulate a new fi le of faults. By checking the new diagnostic history fi le at a later date, you can readily determine whether the problem was indeed completely fi xed.

To clear the diagnostic history fi le, 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.

INSTALLATION CHECKOUT FOR THE CURTIS SPEED CONTROLLER

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 fi nd 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

56409441. NOTE: If you have a programmer with a serial number before 2100 you will need to update your programmer. A free upgrade kit is available, order part number 56409822. Also a different quad 4 pin programmer cable (PN 56409823) is needed to link the programmer to the controller plug-in port.

WARNING!

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.

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.

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.

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 fl ash 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).

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

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).

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.

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 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 fi le.

HANDHELD PROGRAMMER USE

Optional Curtis handheld programmer allows you to program, test and diagnose Curtis controllers. Use of a handheld programmer is described more fully in the CURTIS PROGRAMMER MANUAL 56043101.

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 fl oor 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 specifi c system malfunction. Note: See the Troubleshooting Guide for further information.

An additional special feature of the main control board is to change program settings for a set of specifi c machine functions. See the Main Control

Board Special Program Options section in this manual for further information.

TROUBLESHOOTING GUIDE

Any error codes detected by main control board will be displayed on the hour meter LED display as they occur. If more than one-error exists the display will sequence through the error codes at one-second intervals. The error display will show on the hour meter as the letter E followed by a two-digit code. EX: E03 would be a drive system fault. When troubleshooting any “Fault Description” noted with a double asterisk (**) follow

the instructions for temporarily disabling the control boards special fault detection program. See the Main Control Board Special Program

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 fl ashing green, this indicates that the control is sensing current fl ow 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 fl ashing green. The indicator will be a steady green if the control senses current fl ow through the actuator. It will fl ash green if no actuator current fl ow 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 fl ashing green, this indicates that the control is sensing current fl ow 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 fl ashing green. The indicator will be a steady green if the control senses current fl ow through the actuator.
