Programming Options –SC750 ST and SC800 ST Models (control panel with rocker switches)
Main Machine Controller special program opons allow the service repairperson to match the control board to the
specic model equipment and to user preferences. They also allow adjustments to some machine funcons, and provide
a way to see the controller’s revision level. On ST models each program opon mode is accessed by pressing a specic
conguraon of buons while turning the key on.
Mandatory Program Options
These opons 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 opons. This funcon congures the control unit current sengs, ow rate
sengs, and scrub pressure sengs for each of the scrub deck types.
To check or change the seng:
1. While pressing and holding the vacuum, scrub and soluon switches backward, turn the
key switch on.
2. Wait about 3 seconds unl 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 seng. To change the seng, press the soluon switch forward to increase
the value or backwards to decrease the value. To save the seng, press the scrub switch forward (All LEDs will turn on)
then turn o the key switch.

Baery Charger Selecon –This funcon is used to inform the Main Machine Controller whether or not the machine is
equipped with the oponal on-board charger. If it is, it is also used to inform the controller of what kind of baeries the
machine is equipped with. The Main Machine Controller will request a specic charging prole from the baery charger
to match the baeries.
To check or change the seng:
1. While pressing and holding the scrub and soluon switches backward, turn the key
switch on.

value. To save the seng, press the scrub switch forward (All LEDs will turn on) then turn o the key switch.
