                                           Motion Labs began employing load cell technology, which had been around
                                           for years and used in industrial environments, in its hoist solutions for the
                                           entertainment industry. Load cells attached to the chain hoists give users a real-

“We wanted to meet our                     because any one hoist lifting too much puts unequal weight on the truss. Even

Schneider Electric fit the bill.”          Herrmann thought it made sense to develop a solution that would allow users
                                           to keep their eyes focused on the equipment and not a display.
– Peter Herrmann, President, Motion Labs
                                           “We wanted to create a system that would not only control the chain hoist
                                           and monitor the loads, but also shut the hoist control down if the loads got
                                           out of whack so the problem could be corrected,” Herrmann said. “We thought
                                           this solution would allow users to concentrate on the equipment being lifted
                                           because they would have confidence that the system would shut down if there
                                           was a problem.”
With the help of Schneider Electric, one of the world’s leading suppliers of power,
control and automation solutions, and GCF, a Schneider Electric distributor,
Motion Labs’ brainchild — the WardeN Control Unit — was born.

“Schneider Electric and GCF were very helpful in picking out the components that

                                               The WardeN system’s greatest benefit to customers is not only its ability to offer

                                               define what percentage of weight needs to be out of proportion for the M340 PAC
                                               to stop the chain hoist, and program the PAC with that logic. The most important
                                               time to ensure proper weight distribution is when the riggers are erecting the
                                               trusses. It’s critical to ensure there’s no undue stress on the building. The WardeN
                                               system also is helpful if the equipment being hung is heavier than anticipated. The
                                               chain hoists will stop so that riggers can change the equipment being lifted or add
                                               additional points to allow for the weight.

                                               Like the Cell*Mate system, the WardeN Control Unit gives users the ability to
                                               remotely monitor up to eight channels of load cell data simultaneously on a
                                               constant basis. The Magelis HMIs also allows users to link multiple WardeN
                                               systems together so they can monitor 32, 64 or more chain hoists at one time.
                                               These smaller eight-channel building blocks can be combined to create a
                                               super grid.

                                               “At the new Dallas Cowboys Stadium we created a 100 x 200-foot mega grid to
                                               support all of the traveling acts that perform at the stadium, including the George
                                               Strait concert,” Herrmann said. “The grid consists of six eight-channel controllers.
                                               The WardeN systems watch and control the entire matrix of 45 points and allow
                                               for the movement of the entire grid as one unit, while also analyzing the weight
                                               per eight-channel grid or the weight of each individual point on the truss on a
                                               real time basis.”

                                               According to Herrmann, it’s also cheaper for Motion Labs customers to tie
                                               together multiple eight-channel grids than to build and maintain a custom
                                               32-channel unit.

                                               Motion Labs has been so impressed with Schneider Electric’s products that
                                               they switched over the breadth of their product line to the company. As much
                                               as Motion Labs likes Schneider Electric’s high-quality, commercially available
                                               products, what they found most valuable was the company’s technical support,
                                               application expertise and solutions approach.

                                               For the entertainment industry, the WardeN system is revolutionary. While this
                                               type of technology has been employed commonly in other industries, no one
                                               else in the world has applied it to entertainment before.

                                               “The entertainment industry has an unbelievable safety record,” Herrmann said.
                                               “Riggers are constantly evaluating what they’re doing, checking weights and
                                               making sure things are safe. We look at the WardeN system as validation and
                                               assurance of the work they’ve done. It will ensure everything is safe each and
                                               every time.”

                                                                                                                                                ©2010 Schneider Electric Industries SAS, All Rights Reserved.
