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. CABLE MANAGER

READ THE ASSEMBLY DIRECTIONS AND USER GUIDE!
The assembly directions and user guide are available as free public downloads at Steelcase.com.
Many times, problems can be the result of improper assembly. Were the assembly directions followed
in the assembly of your table?
If you are absolutely certain that the table was assembled correctly, then work through the following
troubleshooting steps.
TROUBLESHOOTING PARTS KIT
Having a spare part that is known to work will quickly lead to accurate identification of faulty components.
Without this, it can be little more that guess work.
We strongly recommend that every dealer maintain a small kit of parts for troubleshooting purposes.
This kit of parts should include:
Lifting Column qty=2 Service part no. 946964900SR
Control Box qty=1 Service part no. 841364900SR
Controller (digital) qty=1 Service part no. 005291DSR
Low Voltage Cable qty=2 Service part no. 003066DSR
Power Cable qty=1 Service part no. 003068DSR
Always maintain a complete kit of troubleshooting spare parts that are known to work properly, to quickly
identify the root cause of problems and resolve customer issues on the first try.
TROUBLESHOOTING STEPS
Step 1: Check for power at the wall outlet; ensure table is properly assembled, and all cables are securely
connected.
Step 2: Check all connections of Low Voltage Cables. Are any of the pins in the connectors damaged or
not making contact? (see Fig. 2 page 5)
Step 3: Obtain a Control Box, Controller, Power Cable, and Low Voltage Cable that are known to work.
Step 4: Using the known good components, test the Lifting Columns one by one (see common procedures).
Replace any faulty Lifting Columns.
Between each of the following steps, be sure to initialize the Control Box (see common procedures).
Step 5: If all Lifting Columns operate properly, progressively swap out parts in the test setup as follows:
A. Swap the known good Power Cable with the original from the non-functioning table. if it stops
working, the Power Cable is faulty.
B. Using the original Power Cable, swap the known good Low Voltage Cable with the original from
from the non-functioning table. if it stops working, the Low Voltage Cable is faulty.
C. Using the original Power and Low Voltage Cables, swap the known good Controller with the original
from the non-functioning table. If it stops working, the Controller is faulty.
D. Using the original Power and Low Voltage Cables and Controller, swap the known good Control Box
with the original from the non-functioning table. If it stops working, the Control Box is faulty.
Be sure to go through all the steps above to fully identify all faulty components. there could be more than one.

COMMON PROCEDURES
POWER-SAVING CONTROL BOX:
The Control Box automatically powers down into”Standby” mode after approximately 10 seconds of inactivity.
During “Standby” mode, the Control Box consumes 0.1 watt of power.
With the Control Box in “Standby” mode, the table can lose power without affecting the synchronization of the Lifting Columns.
However, if the Control Box is still active, and not in “Standby” mode, a power loss will require that the Lifting Columns be
re-synchronized.
Power fluctuations and brownouts can also cause the need for re-synchronization.
Note: The Control Box does not re-set (initialize) by being unplugged and plugged back in.
Refer to the Initialization procedure below.
INITIALIZING THE CONTROL BOX:
In the unlikely event that an error occurs, press and hold the Up and Down arrows simultaneously for 5 seconds to reset the
Control Box.
Synchronize the Lifting Columns as outlined below.
SYNCHRONIZE THE LIFTING COLUMNS:
Operate the table all the way down to the lowest position, and release the Down arrow.
Press the Down arrow again and hold.
After a couple of seconds, the table will give a small, visible “up-down” motion, where the Lifting Columns are finding there
correct bottomed-out position.
The Lifting Columns are now synchronized via the software in the Control Box.
Operate the table all the way up and all the way down to confirm proper function.
TEST INDIVIDUAL LIFTING COLUMNS:
Lifting Columns can be operated individually, even if they are sitting on a bench, not assembled to the table.
Obtain a Control Box that is known to work. Be sure the Control Box is unplugged, or plugged in but in “Standby” mode.
Connect the Low Voltage Cable of the targeted Lifting Column to the known good Control Box.
Connect only to Port/Channel 1 (furthest from the Power Cable).
Obtain a Controller that is known to work, and connect it to the Control Box.
If the Control Box is unplugged from the wall outlet, plug the power cable back in.
With the system hot, operate the individual Lifting Column.
A. Can the Lifting Column be operated through its full range of motion.
B. Does the Lifting Column appear to function normally.
Caution! If the Lifting Column is assembled to the table, first flip the table upside-down and remove Stretcher. This will
allow full and free motion of the targeted Lifting Column, and will prevent damage to the Stretcher and Lifting Column.
Any faulty Lifting Column must be replaced. There are no field-serviceable parts inside the lifting Column.

If any wiring harnesses are damaged, the entire Lifting Column must be replaced.
Faulty Lifting Column To prevent further damage, the Control Box will shut the whole table down if one
Lifting Column is faulty. Test Lifting Columns individually (see Common Procedures),
replace any faulty Lifting Columns.
Faulty Low Voltage Swap with Low Voltage Cable known to work. Use an ohm meter to check cables;
resistance should be near zero. High resistance indicates a fault.
