Washworld High Velocity Middle Limit Flag position

We are very greatful of our Washworld High Velocity system. We are just curious of how others out there with this system have their Middle Limit Flag position set and if any good or bad about the position its set at. Our system has the 26 foot rails which have two sets of holes that the Middle Limit Flag can be fastened to the rails. The holes are aka those closest to the Exit end and those closest to the Entrance ends of the rails. By default the flag is to be positioned at those closest to the Exit end. In that position it looks as if though the boom could take on some unwanted stress due to tight turns and add some load to the overhead swivel etc. So, with those that are running in that position, have you experienced any such issues or is all good and well.
 
we have 19 autos,all are set to the exit. No issues. Small cars will cause your boom to swing hard, but as I stated we have not to many issues.

If you place the flag to the entrance end ,the arm may go wide at the rearof the vehicle.

You may try moving it,and sliding it all the way towards the exit,and see what happens ??? Good luck.
 
Keep in mind that the middle limit flag also triggers things like the air purge at the end of low pressure passes and the exit door opening at the end of the wash. It is spec'd to be located in the exit set of middle holes, and should stay there.

There are also some built in motion timers that are looking for the carriage to hit the middle limit within a certain time, and fault out if it doesn't. Moving the flag to the entrance set of holes may affect this.

I have always set these up with the flag towards the exit, and no real problems with swivels or overhead hoses.
 
Great replies and ideas / thoughts guys!

One other thing I really wonder too and it all probably all depends how fast the carriage is moving on the rails, is just how far past the flag will the carriage travel once the flag is detected and the eyes then see each other. This of course on something short like a Mini Cooper.
 
Mid limit

Hey Kwiki, what a coincidence, my wife calls me that also. On a mini Cooper, the car could be only 5 feet long, it still will not matter, the rear eye doesn't turn on until the mid limit is hit. Then it will look for the signal immediately, if your speed is set at 7-8 or 9 then it will stop fairly quickly. But if the speed is set at 1-2 then sooner. But it has to hit the mid limit first, before the machine will turn on the rear eye.
 
Thanks for all the replies guys. I am sorry to have used the Mini Cooper as an example and am totally aware of the unit not making a stop and turn until the mid-flag is detected and then the eyes making connection.

All of your input helps as to how everyone elses machines are doing in the event of the machine making those tight turns. It was felt at the time of install of ours that the overhead boom swivel (actually both swivels), cross member and hose will take on much less stress and last longer if the flag is placed at the holes on the entrance end. This did work reasonably well other than if you had a short vehicle of course. Doing that allowed the door to start opening sooner but did cause solution application to start running out for about the last foot or so of the passenger side front fender. But, we were wasting solution, water and time by running long. In these days of the economy we need to run efficient but yet keep the integrity of our systems to the utmost in performance and keep'm running.

p.s. The flag has now been moved to where its intended to be and monitoring for the gain of improvement.
