Restore Factory Defaults – This funcon is used to reset all sengs to factory default values. If this is done, the next
me the key is turned on, it will act as though a new controller has been installed and “force” you to set the mandatory
program opons before the machine will operate normally.
To check or change the seng:
1. While pressing and holding the vacuum switch forward and 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 Indicator will remain on and the Fault Indicator will be ashing a numeric value that repre-
sents 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 forward (All LEDs will turn on) then turn o the key switch.
• 1 blink = No
• 2 blinks = Yes
Fault Recall – The fault indicator normally ashes out “current” codes only. This funcon is used by a technician to check
for “historical codes” and clear them.
To check or clear historical codes:
1. While pressing and holding the vacuum and soluon switches backward and the scrub
switch forward, 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 High Soluon Flow Indicator will remain on and the Fault Indicator will be ashing out all historical codes set since
the last me they were cleared. To exit this funcon without clearing codes, press the scrub switch forward. To clear
historical codes press the soluon switch forward.
Fault Detecon - Normally, the Main Machine Controller will perform checks of the electrical system during operaon. If
a fault occurs in a parcular system, that system (and possibly others) will be shut down. This can make troubleshoong
the system dicult. This opon will allow service personnel to disable some of the fault detecon checks to facilitate
troubleshoong. This will not disable the over-current protecon on any of the systems.
To check or change the seng:
1. While pressing and holding the vacuum and soluon switches forward, 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 Medium Soluon Flow Indicator will remain on and the Fault Indicator will be ashing a numeric value that repre-
sents 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.
• 1 blink = Fault Detecon Enabled
• 2 blinks = Fault Detecon Disabled
