Hello all,
I come to you with some questions regarding the functions of several buttons on control panels that I have seen. I'm just curious to learn what all of the numerous buttons do! These buttons in question are on newer Doppelmayr CTEC lifts. I would like to know what each button does, specifically. Also, there is a switch that I did not include a picture of that reads "Spacing System" Off and Hold. What does each position do? Thanks to anyone with the answer!
I recognize these buttons from our older Doppelmayr detachables from the late eighties and mid nineties. Are you certain about the age of the lift?
The "manual launch" button on our gondola is used to send any cabin held in the spacing clutch into the accelerator and on-line before the pre-programmed carrier spacing.
The "C.I.S.-Start" button is for marking a carrier for itentification upon arrival at the opposite station. When it is pushed the next carrier to leave the station will be "identified" by the lift computer and when it approaches the opposite station an alarm sounds in the control room.
The "override anti-collision, override function" when pressed will prevent the anti-collision system from stopping the lift. The override condition stops as soon as the momentary button is released. On our older lifts any anti-collision fault that occurs during an override will still display on the control screen until the reset button is pressed. If the fault messages are left on screen too long the lift will stop. Also, the lifts automatically slow during an override. On older Doppelmayrs it was necessary to override the a-c system during any start-up immediately following turning the controls on. The a-c system typically generates false fault upon power up because some data concerning chair locations in the terminal is lost when the power is turned off. It is the operators responsibility to visually confirm the safe movement of the carriers through the terminal while in override.
The "Spacing System, Off / Hold" switch sounds like the rough spacing controls. Doppelmayr chair lifts I'm familiar with, one with tire conveyors, have two spacing systems. The Fine-Spacing system is controlled by the lifts computers and makes small spacing corrections continuously while the lift runs at any speed. It basically slows or speeds up a small section of the tire conveyor to advance or retard the chairs. The rough spacing system uses magnetic braking-clutches on three of the conveyor tires to "hold" each chair until it is at the proper spacing interval. The process must be started by the operator (a mechanic) by holding chair number one. On newer lifts the computer determines the length of the "hold" but on older lifts the operator must determine the length, usually about 2/3rd the normal length between chairs. A rough spacing lap should be done at a slow speed and generally not when passengers are riding. Only one spacing system is used at time. Generally the rough system is only used occasionally to correct errors greater than the fine system can handle.
I'm familar with the "reserve" button but the only ones I've seen aren't connected to anything. They might be nothing more than a spare button.

) Doppelmayr have been using Pilz since at least 1985 and I would imagine the have been using them since they commenced building detachables.
