A large, backlit LCD displays the operating state (including the run direction, run speed, position and other operating parameters) of all the connected hoists. The main and safety processor monitors all functions. All the contactors and safety circuits needed to protect against overload and slack chain are integrated along with work limit switches and emergency shutdown systems. In addition, the execution of, and internal operating conditions resulting from, all run commands are continuously monitored and assessed.
V-Motion controllers support speeds of from 0 to 29 m/min - as a closed loop system with full torque even for runs over the zero point (reversal of the run direction without the intervention of the brakes). This removes all constraints on the implementation of path- and time-synchronized group and load runs as well as complex transformation sequences, such as those featured in modern studio, theatre and event productions, all of which can be realized without contravening safety regulations.
The clearly laid out user interface makes the configuration and use of the controller intuitive and simple. The operating structure and output displays are logical and easy to follow. Setting-up and emergency operations can be realized using the Up and Down keys and a speed control - obviating the need to connect any ancillary devices.
In the standard versions, the controllers already comply with BGV C1; but optionally they can be upgraded to SIL 3 for overhead stage runs. V-Motion controllers are equipped for operation with Movecat's I-Motion network, whereby up to 99 devices can be operated in directly linked, decentralized group mode or within an I-Motion network by a central controller such as the I-Motion MRC. In network mode, data is transmitted in duplex and the user can follow all the operating parameters centrally.
V-Motion controllers in combination with VMK hoists are especially suitable for professional BGV C1 applications in the studio, theatre, trade fair, events and entertainment, and tour sectors.
