Right. I guess you could include the ring/signal button into the "ready system" equation. CTECs and the new DoppelTecs use a Reset in addition to the Start Acknowledge as well.

On the VX. the station that hit the stop has to give a reset. And I have to reset at the top. then Each station does 2 beeps to say they are "clear for start". However Mid station had a habit of not beeping and ended up getting some very nasty phone calls from both me and the bottom team lead.
Once I have clear from all stations I fire her up.
Once I have clear from all stations I fire her up.
I thought the reset button only had to be used after an emergency stop. I guess it depends on the lift.

On all of the lifts I have been around, the reset button is used after any stop to reset. The reset button resets some minor "faults" such as a normal stop button being depressed, the safety gate being hit and a few other minor things. For anything more, such as a tower fault, etc, a mechanic or qualified person must reset the lift. To reset an E-stop, the emergency brake must be released with a hydraulic pump (on modern lifts) or a hand pump. Depending on ski area policy, I believe the mechanics prefer to reset E-stops themselves to make sure everything is safe before starting the lift.
On modern models, both manufacturers have some form of system that requires both terminals to be ready to start. Doppelmayr, Garaventa, CTEC and any combination of those three usually have a "ready" or "start acknowledge" button at the return terminal, and a "start" button at the drive terminal. Both terminals have a reset button. As KickingHorse said, the terminal that issued the stop must reset the fault, along with the drive terminal.
A scenario with the Doppelmayr, CTEC, Garaventa setup:
-Return terminal presses normal stop button for a fallen skier
-Once skier has been righted and prepared to load, the operator alerts the other operators of the lift. (opposite terminal, or intermediate terminal if equipped)
-To alert the other operators, each ski area approaches this a little differently, but basically the same concept is used. Some areas use Sound Powered phones to communicate. Since sound powered phones don't ring, the operator uses the "Ring," "Signal" or "Alert" button. (can be labeled differently on different lifts) When depressed, this button produces a high pitched beeping noise at all terminals, audible inside the terminal, outside the terminal, and in the operator house. Each area can have different codes for this button. For example, one long beep could mean pick up sound powered phone. Two beeps could confirm all clear and ready to start. Another option is an actual phone that rings. Usually the "signal" button is used to confirm the all clear immediately after resetting and before starting. And finally, some areas use the signal button solely. It all depends on ski area preference and local authority codes.
-An all clear has been confirmed by phone or signal. The return operator must now press the reset button and signal to the drive terminal operator to reset.
-Both terminals have pressed reset, so the return terminal presses the "ready" or "start acknowledge" button. At the drive terminal, the start button in the operator house will light up green or a "ready" light will come on. This allows the drive operator to press the "start" button, which must be held down for 2 seconds after the lift starts moving. Should the operator remove their finger from the button before then, the lift will stop and require the drive operator to reset the lift.
Please note that this can vary based on lift age, region, ski area preference/modification, etc.
Here are some pictures of these setups:

Number of downloads: 60 This is a GaraventaCTEC return terminal setup. The buttons from left to right, top row to bottom row: Reset, Start Acknowledge, Emergency Stop, Fast, Slow, Medium, Ring, Normal Stop.
On Poma and Leitner-Poma lifts, the terminal where the stop was generated must reset, along with the drive terminal. (if different) Only the drive can start the lift. Again, each terminal must confirm via phone and/or signal that they are ready. On some Leitner-Poma lifts, there is a start button at the drive and return terminals. The return terminal cannot start the lift, but must press their start button to allow the drive terminal to start it. I haven't seen this on all Poma and Leitner-Poma lifts, just a few. I believe this could be by request.
Here are some pictures of Poma and Leitner-Poma setups:

Number of downloads: 60 Return terminal controls without start button. The buttons from left to right, top row to bottom row: Emergency Stop, Slow, Chair Mark, Reset, Normal Stop, Fast, Signal.

Number of downloads: 46 Return terminal controls with start button. The buttons from left to right, top row to bottom row: Emergency Stop, Normal Stop, Slow, Reset, Chair Mark, Signal, Start. (you may have noticed that there is no fast button. On this lift, only the drive terminal can speed the lift up.
On newer Leitner-Poma lifts, the drive terminal pedistal usually has an amber colored, lighted pushbutton to activate the emergency brake pump. I will try to get a picture of new drive and return pedistals from L-P. Most other lifts have this button on the main drive terminal control desk.
Hopefully this clarifies some questions. Again, please note that this may vary from ski area to ski area, and it doesn't make that ski area or lift a "bad" or a less safe one. It's just different system.
