INTRODUCTION

When the scrubbing mode is used on the

5680/5700, water flows from the solution tank
through the pinch valve to the solution solenoid
valve to the scrub brushes. The brushes scrub the
floor. As the machine is moved forward the
squeegee wipes the dirty solution off the floor,
which is then picked up and drawn into the
recovery tank by the vacuum fan.

ELECTRICAL SYSTEM

The 5680/5700 electrical system consists of the

batteries, electrical drive motors, scrub brush
motors, vacuum fan motors, power control panel
and related components. This section includes
information on these components and their
troubleshooting.

 ELECTRICAL

BATTERIES

The batteries are unique in that they hold their

power for long periods of time. The lifetime of the
batteries is limited by the number of charges the
batteries receive. To get the most life from the
batteries, charge them when the battery discharge
indicator flashes.(XP and XPS only). The 5700
standard has an analog gauge.

Periodically clean the top surface of the batteries

and the terminals, and check for loose
connections. Use a strong solution of baking soda
and water. Brush the solution sparingly over the
battery tops, terminals, and cable clamps. Do not
allow any baking soda solution to enter the
batteries. Use a wire brush to clean the terminal
posts and the cable connectors. After cleaning,
apply a coating of clear battery post protectant to
the terminals and the cable connectors. Keep the
tops of the batteries clean and dry.

Keep all metallic objects off the top of the

batteries, which may cause a short circuit.
Replace any worn or damaged wires.

Check the electrolyte level in each battery cell

before and after charging, and after every 50
hours of operation. Do not charge the batteries
unless the fluid is slightly above the battery plates.
If needed, add just enough distilled water to cover
the plates. Never add acid to the batteries. Do not
overfill. Always keep the battery caps on, except
when adding water or taking hydrometer readings.

FOR SAFETY: When Servicing Machine,

Avoid Contact With Battery Acid.

Measuring the specific gravity using a hydrometer

is a way to determine the charge level and
condition of the batteries. If one or more of the
battery cells reads lower than the other battery
cells (0.050 or more), the cell is damaged,
shorted, or is about to fail.

NOTE: Do not take readings immediately after

adding distiled water. If the water and acid are not
thoroughly mixed, the readings may not be
accurate. Check the hydrometer readings against
the following chart to determine the remaining
battery charge level:

MACHINE DIAGNOSTICS TEST

PROCEDURE--MODEL 5700 XP / XPS

The 5700XP and 5700XPS can be tested to verify

that the electrical components and systems are
functioning properly. The machine’s touch panel is
used to perform this test.

TO RUN MACHINE DIAGNOSTICS

1. Turn the machine on--off key switch OFF.
2. While pressing squeegee/vacuum button on
the touch panel, turn the key switch back on.
The button must be held down to the count
of ten. Release the button.

All outputs will turn on and off in sequence while

running diagnostics.

NOTE: To get out of the diagnostics mode at any

time turn the key off, then back on.

The diagnostics program will start and all three

speed indicators will flash.

While the diagnostics program is running, the

machine outputs will be turned on in the
following order:
1. The brush and squeegee actuators are
raised to the up position.

2. The vacuum fan is turned on. The

squeegee runs down until the actuator
stops. The actuator will then run up to the
top position. The vacuum fan is turned off.

3. The brush actuator runs down for about

2 seconds and stops. The actuator runs
up until it stops.

4. The brushes are turned on for about 3

seconds.

5. The water valve is turned on for about

2 seconds.

6. The ES pump is turned on for about 2

seconds.

7. The vacuum fan is turned on for about

2 seconds.

8. The brush is turned on for about 2

seconds.

9. The errors are displayed.

4 -- 216 5680/5700 MM406 (6--03)

Downloaded from www.Manualslib.com manuals search engine

 ELECTRICAL
When all three speed indicator lights stop
flashing the diagnostics program is complete
and the error codes are displayed using the
touch panel lights.

NOTE: The three speed indicator lights represent

the position of the forward/reverse potentiometer
at this time. With the machines speed handle in
the neutral position the number two indicator light
should be on. This indicates a true neutral
condition. If the number one or number three
speed indicator light is flashing or is on, the
forward/reverse potentiometer needs to be
adjusted to achieve true neutral.

3 Record the existing error codes and turn the

key switch off and back on to get out of the
diagnostic mode. Refer to the chart on the
following page to identify diagnostic error
codes.

FaST TM advantages

Less potential water left behind -- reduced slip/fall

Conventional FaST
Micro--dispersed bubbles allow FaST solution to dry quicker than
conventional liquid.

Reduced detergent cost, waste,

shipment cost, storage

Conventional FaST
On--board detergent metering
One container lasts weeks
Just drain recovery tanks and fill solution tank with water --
no chemical mixing
Less water used/recovered solution to dispose of --
environmentally friendly

Solution Expansion

Air Pump, all 24vDC pumps,36vDC FaST system(s) uses a

power resistor
Pump runs continuously with FaST engaged
The air pump/compressor produces 20--30 psi, 20--25 inches of Hg
By the use of added air to the detergent/water solution, the solution
expands to over four (4) times its original volume after air is injected.

Check Valve
Prevents detergent/water solution from entering the air compressor/pump

Mixing Chamber
Ensures proper mixing of detergent/water solution
A media similar to a 3M Red Pad is used
