Here are my control panel's pictures. I used to word at Mega-Parc in Quebec city, the second largest indoor amusement park in North America.
The first picture is the control of the Spring ride from Moser. It's been manufactured in 2001. It's the original control box, that has been a little modified.
Control explanation :
1 - Ligthing control
2 - Safety bar closed : the pilot light lit when all the safety belts are in the closed position. If the light isn't lit, the ride can't start.
3 - Control panel on/off
4 - Hydraulic pump on/off
5 - Ride counter : It counts the number of time the ride has been started.
6 - Alarm reset : The light lit when there is an error with the position's sensor or other internal circuitry. Push the button to reset the alarm.
7 - Bell : it's been added. The bell has to be ringing to start the ride.
8 - E-stop : It has been modified. At first it needed a key to reset it and when we pushed it, the ride would stop and stay in its position. The mechanics had to come and reset the ride. Now, it's a classic push-turn button. When it's pushed, the pump shut off, and the ride comes back to the loading area.
9 - E-stop pilot light : turns on when the e-stop is pushed or if the ride puts itself into e-stop mode.
10 - Cycle start : to start the ride, the safety belt pilot light must be turned on and we must push the bell and start button at the same time.
11 - Cycle abort : brings the ride back to the loading area with a programmed sequence (in opposition to the e-stop which turns off the pump and open the cylinder valve to bring the ride back to the loading platform)
Second picture is the controls from the ride "Up, up and away" from Zamperla. The ride has been installed in 1988 and I'm pretty sure that the control panel is not the orginial one (even if it looks old).
1- Ride duration : Each number equals about 2 minutes, so you can see that the duration of the ride is about 3min
2 - Up timer : There is a delay between the beginning of the rotation of the ride and the moment the ride starts to lift. Each number equals 10 seconds.
3 - Control panel on/off : when it's off, the alarm can still be used
4 - Manual/automatic mode
5 - E-stop : stops the ride in any position
6 - Cycle start
7 - Cycle stop : brings the ride back to the loading area with a programmed sequence. The ride comes back to the ground, then the motors are stopped and the brakes engaged.
8 - Accoustic alarm
9 - Lift gondolas : Lift the center of the ride if the Auto/man selector is in the manual position.
10 - Gondolas down : Bring the center of the ride back to the ground if the auto/man selector is in the man position.
The two last buttons has to be maintained pushed for the ride to move. At the moment the button is released,the movement stops.
Finally, the last picture represents the controls of two rides : kiddie bumper cars and adult bumper cars. The kiddie version is from Zamperla and the adult one is from Bertazzon. The two control panels were built by the mechanics of the park to replace the older ones (who were not the original ones by the way).
1 - Digital timer : the ride duration is 3 minutes
2 - Control panel on/off
3 - Speed #1 and speed #2 : on the kiddie version, the speed #2 isn't wired to a contactor, so only speed one is available. On the adult version, the two speeds are wired to a contactor, but, the voltage of speed #1 isn't sufficient to make the cars move. So, only speed #2 is used. Note : there is also two other contactors in the electrical panel for Speed #3 and Speed #4. But, the bumper cars go too fast if those speeds are used, so they are not wired to the control panel. People could hurt themselves if they were used, as it's going really fast.
4 - E-stop which cuts the power to the cars
5 - Accoustic alarm
I'll try to have some pictures of other control panel, but I'm not an employee anymore, so it may be a little more difficult. I would really like to show you the roller coaster panel (Mack 1988)
Finally, sorry if there is some mistakes as english is not my native language.
