I don,t know what the setting is for the Kone..But depending on your state codes..Vertical Combs are tested on the Schindler, Otis Escalators using a gauge measuring lbs.per square inch lift device is installed between lifting angle spanning across both newel ends a comalong is attached to the angle and the other end supports a gauge which is hooked by cable to a bracket mounted on the comb..by cranking up on the lift comb plate lifts gauge will read the point at which switch trips..by watching your faults trigger you can determine if it is set..........350lbs sounds right adjust switches accordingly..

In my home state, California, the requirement is that the switch trip at no more than 150# vertical (left, right, center) and Horizontally no more than 400# (left, right) and no more than 800# (center). Top and bottom.
I have seen the method you describe, and its all fun and games till the glass balastrade breaks in tiny little pieces or the board across the top of the balastrade slips and hits some one in the head.
Kone sells a POS lightweight hydraulic unit. www.stoplossresources.net makes a much nicer one that is a lot quicker to set up and do.
You don't always get what you pay for, but you always pay for what you get. I would recommend the stop loss product.

That being said and thank you for your response, I am looking for the procedure for adjusting the switch in question.

I'm using the Stop Loss unit. It's da bomb!

Note that when doing the vertical adjustment or test on the Kone ECO 3000 escalators, there is sort of a lever-action, between the floor plate pivot point, and where the force of a stuck foot would contact the leading edge of the combplate, and deflect it upwards. If you were to remove the combplate during testing or adnustment, this would make the "lever" only half as long. If you apply your testing force at the edge of the landing plate, (where the combplate attaches), you would be misadjusting the action. You would need twice the force to make the switches trip, because the "lever" is only half as long, with the combplate removed. This does not truly represent the vertical actuation of the combplate switches if struck by a foot or shoe.

In contrast to the above, When the combplate is installed, the "lever" is now approximately twice as long, requiring half the force to trip the switches. IMO, this is how the force should be applied during testing and adjustment. The reason being, that this is how the unit actually runs, when completely assembled, and the public is using it.

I took an old combplate, and modified it just a bit, so that the Stop Loss tool applies it's force to the leading edge of the combplate, as closely as possible representing the actual conditions during normal usage. The specially modified combplate stays with the Stop Loss tool for all testing and adjustment.

That's a great idea. Still looking for a method or process of adjusting the switch. Spring length? Throw of the leaver etc.

Oh, right! You did say that...

I can't picture t right now, but I think we tweaked the spring length as needed, leaving the switch with just like 1/16th gap, where the linkage wouldn't rattle the switch under running vibrations

Keep in mind the more you pre load the spring the more pressure it will take to activate the switch. Whicu will need a smaller gap between the arm and switch. It's a delicate balance. In the past I have found a couple of different items that cause problems.1, debris be hind the comb plate roller. 2, the bolt that goes through the roller being bent.
I do not remember the measuremental but there is a certain length the spring is pre loaded to. I think 21mm but it's been a a couple of years
