Troubleshooting Guide
SERIES 7 TABLES
PRE-DECEMBER 2015
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 carry low voltage.
•
The Control Box contains a computer processor 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 the Preset buttons.
•
Preset data is stored in the Controller itself, not in the Control Box.
