OLOGY HEIGHT-ADJUSTABLE DESKS
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 computer processor with embedded software controllers.
•
The Control Box controls all aspects of Desk motion, and synchronizes motion of the individual
Lifting Columns.
•
The Control Box will shut down the entire Desk 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 Desk to prevent further damage.
•
The Controller is the user interface to the Desk, and directs all Desk movements via the Up-Down
buttons and the Preset buttons.
•
Preset data is stored in the Controller itself, not the Control Box.
