Form Number 56043150 Page 29
Programming Options –SC750 ST and SC800 ST Models (control panel with rocker switches)
Main Machine Controller special program opons allow the service repairperson to match the control board to the
specic model equipment and to user preferences. They also allow adjustments to some machine funcons, and provide
a way to see the controller’s revision level. On ST models each program opon mode is accessed by pressing a specic
conguraon of buons while turning the key on.
Mandatory Program Options
These opons are used to “inform” the Main Machine Controller how the machine is equipped. They must be set any-
me the Main Machine Controller is replaced and they must be set correctly for the machine to operate as it should.
Scrub Deck Type – There are 3 scrub deck opons. This funcon congures the control unit current sengs, ow rate
sengs, and scrub pressure sengs for each of the scrub deck types.
To check or change the seng:
1. While pressing and holding the vacuum, scrub and soluon switches backward, turn the
key switch on.
2. Wait about 3 seconds unl all of the LEDs light up and then go o. Release the switches.
The Regular Scrub Pressure and Heavy Scrub Pressure Indicators will remain on and the fault indicator will be ashing a
numeric value that represents the current seng. To change the seng, press the soluon switch forward to increase
the value or backwards to decrease the value. To save the seng, press the scrub switch forward (All LEDs will turn on)
then turn o the key switch.
• 1 blink = 28 Inch Cylindrical Brushes
• 2 blinks = 26 Inch Disc Brushes
• 3 blinks = 34 Inch Disc Brushes
Baery Charger Selecon –This funcon is used to inform the Main Machine Controller whether or not the machine
is equipped with the oponal S.P.E. on-board baery charger (The S.P.E charger was used on early machines. Later
machines use the Delta-Q IC650 baery charger). It is also used to inform the controller of what kind of baeries the
machine is equipped with. The Main Machine Controller will request a specic charging prole from the S.P.E baery
charger to match the baeries.
To check or change the seng:
1. While pressing and holding the scrub and soluon switches backward, turn the key
switch on.
2. Wait about 3 seconds unl all of the LEDs light up and then go o. Release the switches.

value. To save the seng, press the scrub switch forward (All LEDs will turn on) then turn o the key switch.
• 1 blink = Not equipped with on-board charger
• 2 blinks = On-board charger with WET 25A baeries (Use with 242 AH WET Baeries 56206079 or 310 AH WET
Baeries 56391391)
