SERIES 9 TABLES: HOW THEY WORK
Each Lifting Column contains an individual motorized lift mechanism.
The Control Box contains a power transformer. This converts high voltage AC current from the wall
outlet (120v or 240v) to low voltage 18v DC current which powers the Lifting Columns.
Only the main power cable carries high voltage. All other cables are Low Voltage.
The Control Box contains a mini-computer, with embedded software controllers.
The Control Box controls all aspects of table motion and synchronizes motion of the individual
Lifting Columns.
The Control Box will shut down the entire table if a fault is detected. For example, if one Lifting
Column is binding or trapped, it will draw significantly more current than the other Lifting
Column, and the Control Box will shut down the entire table to prevent further damage.
The Controller is the user-interface to the table, and directs all table movements
via the up-down buttons and preset buttons.
Preset data is stored in the Controller itself, not the control box.
