Kegel FLEX 17-5801 Operator's Manual page 27

duster up switch's normally open contacts will close to turn off the duster wind-up
motor. If the contacts do not close there will be a DUSTER WINDUP error displayed.
16. There are two ways to reverse the Walker or Flex. In this scenario, the LDS sensor
stops the machine and the alarm buzzer will sound to alert the operator.
17. The other option is the Stop by Sensor. The machine will be signaled to stop when
the Sensor goes passed the tail plank and trips before the LDS. Using both functions
to stop forward travel creates a back-up method for the stopping the machine.
18. When the Walker reaches its travel distance and comes to a stop, the squeegee will
proceed to lift up and stop when the squeegee up switch normally open contacts
close. If the contacts do not close, a SQUEEGEE UP error will be displayed.
19. If the Pindeck Treatment function is disabled, the Walker will then start traveling in
reverse and stop after moving 14 inches. The squeegee will lower and the machine
will go forward again and stop, then lift the squeegee. This function helps to remove
drips off the squeegee blades. If the Pindeck Treatment function is enabled the
machine will start moving in reverse until the cleaner head assembly is line with the
2-3 pin deck spots then drop the duster.
20. The machine will then start up the moving head to apply the Pin Deck Treatment.
After application of Pindeck Treatment the machine will wipe it onto the Pindeck and
stop with duster on back row of spots then duster will lift.
21. The Walker will now travel in reverse, turn the vacuum off, and run the cleaner pump
in reverse for 1 second to help reduce pressure on the cleaner tip.
22. As the Walker travels in reverse at high speed the lane distance sensor is counting
inches traveled and is also monitoring the movement of the machine. If travel is
interrupted, a REVERSE TRAVEL error will be displayed.
23. As the Walker reaches the Lower Buffer Brush and Turn on in Reverse location, it will
begin to lower and stop in its down position when the brush down switch normally
open contacts close. If the contacts do NOT close a BRUSH DOWN error will be
displayed. If the brush down switch sticks closed when it should be open, it will give
a BRUSH UP error.
24. The brush will begin buffing at the pre-determined distance as the Walker travels in
reverse. The oil head will start back up again when it reaches the first reverse load
distance.
25. As the Walker continues to travel in reverse it will be down-shifting to lower speeds.
After the Walker applies the last reverse load the moving heads will park.
