Control SystemService Manual – Warrior ST, AXP, EcoFlex 16seconds the pressure will change to the extreme scrub mode. At the same time the panel display will showthe correct changed scrub pressure settingScrub OFF Switch (E): Pressing this switch when the unit is in a scrub mode will cause the following:• The scrub brushes will turn off. the scrub deck will be raised to the up position, and the solution flow willbe stopped• The first time that this switch is pressed, the vacuum system will NOT be turned off. This is so that anyremaining water may be picked up without having to turn the vacuum back on. If this switch is presseda second time (pressed after the scrub system has been turned off) the vacuum will shut off after a 10second delayWand Switch (F): This switch is used when an external vacuum/scrub wand is used. Pressing this switchwill turn the vacuum on continuously without regard to the throttle position If the scrub system was on itwill be turned off. This includes turning off the scrub brushes and turning the solution flow off (to the scrubdeck). Note: automatic shutoff of the vacuum motor when the recovery tank is full is disabled whenthe wand is enabled.Extended Scrub (Recycle) Switch (G): Extended Scrub is available only on Warrior ST and AXPmodels. Pressing this switch will turn on or off the extended scrub option. When extended scrub is active,a portion of the solution to the scrub deck will come from the recovery tank. By recycling some of the usedsolution with some new solution, the overall scrubbing time of the machine can be extended before refillingthe solution tank or emptying the recovery tank. See the main programming options in this manual to select(activate) the recycle option. Purge Function: To prevent buildup of debris in the recycling lines and pump,the system should be purged after use. Drain the recovery tank and fill with clean water, and then push andhold the extended scrub switch for 3 seconds to initiate the purge function. The purge will run for 20 secondsto flush the lines. Note: Failure to purge the recycle system after use may cause the extended scrubpump and/or solenoid valve to become fouled.Chemical Switch (H): The chemical (detergent mixing) option is available only on Warrior AXP andEcoFlex models. Pressing this switch will turn on or off the chemical option. When active, a small pumpwill inject chemical (detergent) into the solution line upstream from the scrub deck. The chemical pumpis disabled any time the solution system is inactive See the main programming options in this manual toselect (activate) the onboard chemical distribution system.EcoFlex Switch (I): This option is available only on EcoFlex models. By default, the EcoFlex cleaningmode is active during normal operation to conserve solution and detergent. Press this switch for 2 secondsto override the EcoFlex cleaning mode and temporarily increase scrub pressure, solution flow, and thedetergent ratio. See the main programming options in this manual to select (activate) the EcoFlex option.Control Panel IndicatorsEach of the switches on the control panel have an indicator LED adjacent to the switch. Most LEDs aredual channel and provide two colors within the same LED. In general, the following guidelines apply to thecontrol panel indicators, and various exceptions to this rule are listed separately:A steady green indicator means that the particular system or function is onA flashing green indicator means that the particular system is in a delayed-off condition. An example ofthis is when a scrub mode is selected and the throttle goes from forward or reverse to neutral. When thishappens the vacuum indicator will flash green indicating that the vacuum is still on but that it will beturning off after the delay periodA steady yellow indicator means that the particular function has been enabled and in a ready state, butis not currently on. For example, if a scrub mode is selected and the throttle 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 and/or reverseA flashing yellow indicator means that a fault has occurred in the particular system. An example of thiswould be an over-current fault on one of the motors.
