FLEX Walker Sequence of Events - "How it Works"
The following steps detail how the Walker operates. Skip to Page 15 for the FLEX. The
Walker should be on the approach in the down or operating position behind the first lane
with the HOME SCREEN showing. The machine needs to be in CLEAN & OIL MODE for the
following sequence of events to occur. The following sequence will explain how to start the
machine, how the errors work, and what happens as the machine travels down your lanes.
If errors are present, the recovery tank is missing, or the duster cloth low there will be a
message indicating this on the Home Screen.
1. Press the GO TO STARTING LANE button to advance to the starting lane screen.
Choose the starting lane then press GO TO ENDING LANE and choose the ending
lane. After choosing the ending lane, press START MACHINE the machine will change
to a screen that will ask you to double check your info. If it's correct press YES and
the machine will be ready to operate.
2. The Walker starts moving toward the lane using two drive motors, each monitored
by a proximity sensor. If the 7-pin motor sensor fails to receive a signal while on the
approach, there will be an APPROACH 7 PIN error. If the 10-pin sensor fails, there will
be an APPROACH 10 PIN error.
3. The OLS error is also active when the Walker is moving toward the lane. If the On
Lane Sensor (OLS) does not close the contacts in 8 seconds, then the PLC assumes
that the machine has failed to seat on the lane or it is going too slowly and displays
an OLS LATE error. If the OLS sensor is actuated before the machine goes into the
lane an OLS STUCK ON error will be displayed.
the touchscreen and in their appropriate section.
4. As the Walker moves toward the lane, the squeegee, duster, cleaner pump, and oil
head will start up at their individual preset distance. The duster cloth is monitored
by the duster up switch. If the switch's normally open contacts do not open up,
there will be a DUSTER EMPTY error displayed. The squeegee will move down and
stop when the down switch normally open contacts close. If the switch contacts do
not close there will be a SQUEEGEE DOWN error displayed. Finally, the oil pump will
turn on.
5. As the Walker enters the lane the 10-pin whisker sensor will just brush the foul light
which will turn on the steering relay. This will cause the machine to go into its
steering function. The 7-pin motor will slow down due to the steering relay opening
up the power to the motor. At the same time, the 10-pin motor will continue to run to
turn left. When the 10-pin whisker sensor comes off the foul light the machine will
either be lined up with the lane or the 7-pin whisker sensor will come in contact with
the left division rail. If the 7-pin whisker touches, the machine will turn back to the
right and will most likely be lined-up with the lane.
