For example, if the scrub system is off and the operator is not on theseat, the scrub system indicator will be red indicating that the system cannot be turned on until the operator is on the seat.A flashing red indicator means that a fault has occurred in the particular system. An example of this would be an over-current fault.A yellow indicator means that the particular function has been enabled but is not currently on. For example, if a scrub mode is selected and thethrottle is in neutral, the scrub system, vacuum, and solution indicators will all be yellow indicating that the systems are enabled and ready to turnon when the throttle is moved to forward or reverse.A green indicator means that the particular system is on.A flashing green indicator means that the particular system is in a delayed-off condition. An example of this is when a scrub mode is selected andthe throttle goes from forward or reverse to neutral. When this happens the vacuum indicator will flash green indicating that the vacuum is stillon but that it will be turning off after the delay period.Scrub Mode Off Indicator (34):• This indicator will be RED if the scrub system is inhibited for any reason. Possible reasons are:• Seat switch is open• The scrub deck has not returned to the UP position.• A system fault• Low voltage condition• This indicator will be GREEN if the system is ready to be placed in either the normal or heavy scrub modes.• This indicator will be OFF if either the normal or heavy scrub modes have been selected.• This indicator will flash RED if there is a fault in one of the scrub system components. This will be accompanied by an error indication onthe Hour Meter / Status Display (32).Normal Scrub Mode Indicator (35):• This indicator will be YELLOW if the normal scrub mode has been selected but the scrub motor is off. This will be the case if the throttle isin the neutral position. The scrub motor will stay on for approximately 3 seconds after the throttle returns to the neutral position.• This indicator will be GREEN if the normal scrub mode has been selected and the scrub motor is on.• This indicator will be OFF if the scrub mode is off or if the heavy scrub mode has been selected.Heavy Scrub Mode Indicator (36):• This indicator will be YELLOW if the heavy scrub mode has been selected but the scrub motor is off. This will be the case if the throttle isin the neutral position. The scrub motor will stay on for approximately 3 seconds after the throttle returns to the neutral position.• This indicator will be GREEN if the heavy scrub mode has been selected and the scrub motor is on.• This indicator will be OFF if the scrub mode is off or if the normal scrub mode has been selected.Vacuum System Indicator (37):• This indicator will be YELLOW if the vacuum/squeegee system is in the AUTO mode and the throttle is in the neutral position. This indicatesthat the vacuum system is enabled but the vacuum is currently off.• This indicator will be GREEN if the vacuum is currently on. This indicates that the system is in the AUTO mode and the throttle is not in neutralor that the vacuum system is in the ON mode.• This indicator will FLASH GREEN if the shutoff delay is keeping the vacuum on. This occurs if the vacuum system is in the AUTO modeand the throttle goes to the neutral position. This will also occur if the vacuum system is turned off while it was in either the AUTO or ONmodes. The shutoff delay will turn the vacuum off after the delay period.• This indicator will be OFF if the vacuum/squeegee system if in the OFF mode.Vacuum System Fault Indicator (38):• This indicator will flash red if there is a fault in the vacuum or squeegee systems. This will be accompanied by an error indication on the HourMeter / Status Display (32).• This indicator will be RED and the Hour Meter / Status Display (32) will show “FULL” if the recovery tank float valve has closed. If this indicationoccurs and the tank is not full, see the Troubleshooting section.Solution System Indicator (28):• This indicator will be YELLOW if the solution system is in the AUTO mode and the throttle is in the neutral or reverse positions. This indicatesthat the solution system is enabled but the solution flow is currently off.• This indicator will be GREEN if the solution system is in the AUTO mode and the throttle is in the forward position. It will also be GREENif the solution system is in the MOMENTARY ON mode. This indicates that the solution flow is currently on.• This indicator will be OFF if the solution system is in the OFF mode.Solution System Fault Indicator (24):• This indicator will flash red if there is a fault in the solution system. This will be accompanied by an error indication on the Hour Meter / StatusDisplay (32).revised 10/01
