Extra Info on LCD
This screen selects the extra information that can be displayed real-time on the LCD. This aids in
troubleshooting the machine in normal operation. The default is to display no extra info. If extra
information is selected for display, a 2-letter or 3-letter code is displayed to identify the information,
while underneath the code is a number. The number indicates a value in amps, volts, or is without a unit
designation depending upon what is selected. Only one piece of extra information can be displayed at any
time, but the selected information can be changed at will via the hidden menu. Press DETERGENT button
to back out of the menu and save the selection. Cycle the Key Switch to return to normal operations mode. A
summary of the identification codes shown on the LCD display is as follows:
• BV = Battery Voltage
• LOK = Battery Lock Level
• FBR, RBR = Front/Rear Brush Motor Current (Instantaneous or Average)
• VAC = Vacuum Motor Current (the sum of two vac motors)
• MSO, RSO = Maintenance Solenoid Current & Restore Solenoid Current
• MST = Misting Solenoid Current
• BCO, VCO = Brush Contactor Current, Vacuum Contactor Current
• BAC, SAC = Brush Actuator Current & Shoe Actuator Current
• CP, SP = Chemical Pump Current & Solution Pump Current
• HRS = Brush On-Time Hourmeter
See Figure E-27 for a list of all available info that can be selected for display.
