• 4 blinks = On-board charger with GEL EXIDE 25A baeries
• 5 blinks = On-board charger with GEL-AGM 25A baeries
• 6 blinks = On-board charger with WET 15A baeries
• 7 blinks = On-board charger with GEL-AGM 15A baeries
Additional Program Options
The following opons can be used by the technician or to set user preferences.
Low Voltage Cut Out Selecon –The purpose of the low baery voltage cutout funcon is to help prolong baery life.
The scrub deck will be raised and the brush motors, vacuum motor, and soluon solenoid valve will turn OFF automa-
cally and cease to funcon when the baeries discharge to the selected cutout level. The cutout level is adjustable
between two sengs. The standard seng (wet cell/lead acid) is 20.55 volts and alternate seng (AGM) is 21.75 volts.
To check or change the seng:
1. While pressing and holding the vacuum and scrub 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 yellow Baery Indicator 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.
• 1 blink = Wet Baery 80%, 20.55V
• 2 blinks = Maintenance Free Baery 70%, 21.75V
Lock Out Brush Pressure - It is possible to lock out either brush pressure seng: Low or High. During normal operaon,
the brush pressure that is locked out will not be able to be selected.
To check or change the seng:
1. While pressing and holding the vacuum 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 green Baery Indicator will remain on and the fault indicator will be ashing a numeric value that represents the cur-
rent 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 = No pressure seng locked out.
• 2 blinks = Low pressure seng locked out.
• 3 blinks = High pressure seng locked out.
