Service Manual – Focus II / Scrubtec R6 Rider Autoscrubber
Vacuum Selection
The Focus machine may contain an optional second vacuum motor. It is important that this option be
identified to the controller in order for the controller to properly monitor the amperage for one or two motors.
If this option is not properly set, the Main Machine controller may report an over-current error.
• 1 Vacuum Motor
• 2 Vacuum Motors
Low Voltage Cutout
This option protects the batteries from being overly discharged. When the battery level reaches the low
voltage cutout threshold, the scrub system will shut off. The value of the low voltage cutout is dependant on
the type of battery being used, as described below.
• Main (Maintenance) Free Battery 70%
LVC = 21.75V
• Wet Battery 80%
LVC = 20.55V
Max (Maximum) Scrub Speed
This function is not currently implemented and maximum scrub speed is not limited (100% of transport
speed).
• 100% of Transport
Lockout Brush Pre (Pressure)
This function is not currently implemented. Certain scrub pressures can be locked out so they are not
selectable during normal operation. If two pressures are locked out, then the machine will operate with only
the single remaining pressure available.
• 1. None
Lockout Sol (Solution) Flows
This function is not currently implemented. Certain solution rates can be locked out so they are not
selectable during normal operation. If two rates are locked out, then the machine will operate with only the
single remaining solution rate available.
• 1. None
Chemical (Detergent) Rate Bias
This function is not currently implemented. To ensure that the actual detergent rate is consistent with the
user-selectable ratio, the rate can be biased up or down by 10%.
• 1. None
Deck Down Time
The initial lowering of the scrub deck is timed, because there will not be any brush motor amperage to
monitor for determining when to stop lowering the deck. This is used by engineering during development.
Under normal circumstances, this should not need to be changed.
• x.x Seconds
(1.0 to 5.0 in 0.1 increment)
Restore Defaults
Activating this setting will restore all of the memory settings to their factory default values. When the key
switch is next turned on, the controller will enter program mode to set the deck type.
