We use OPTO 22 equipment to replace our aging Energy Management System. The original CSI (Control Systems International, now part of TAC/Schneider Electric) system was installed when they built the park in 1991. The original system was a square peg crammed into a round hole.
Because of the capabilities of PAC Control we were able to write our own program that was customized for our operation. PAC Display is used as our Maintenance Team member interface and Groov is used for all other departments. Groov has made it easy for us to allow anyone remote access to the system.
Pictured below is the transitioning of one location from the old system to the new OPTO 22 based system.
Because of the wide variety of input and output cards and the easy flow chart programming we use our OPTO 22 system to monitor wind and temperature conditions in addition to controlling the lights and HVAC. This enhanced capability is used to control stack lights at some rides to alert ride operators to adverse wind or temperature conditions. The frequency measuring commands in the EB1 brain is used to calculate wind speeds at the brain level.
Trends of weather data using Groov is used to help management make better decisions
We do our panel building in-house and use SNAP-TEX cables to keep things clean and organized
We control almost every variety of HVAC equipment including refrigerant, chilled and hot water, vent-hoods, exhaust fans, etc. We upgrade floating point valves to analog valves for easier troubleshooting in the future.
As we change over to the OPTO 22 based system we consolidate and simplify as we go. One SNAP Brain can replace 6 to 8 of the old Unitary Controllers (CSI Brains)
