INSTRUCTIONS

1. FLIP WORKSURFACES AND PLACE TOP SUPPORTS
   Flip worksurfaces upside down and place on floor as shown. Add all four top supports to each end of both work surfaces. Do not attach top supports to the worksurface at this time

2. ATTACH TOP SUPPORTS TO COLUMNS
   Ensure the mounting holes in the column remain aligned with the corresponding holes in the beam or independent beam. Align the beam or independent beam to the top support. Assemble using the M8x1.25 x 12mm length screws (4 per column) and a T40 Torx driver. Be aware that the mounting holes may not be tapped. As they are inserted, the provided M8x1.25 x 12mm length screws will form their own fastening threads if none are already present. Average fastening torque of 8Nm (6 lbs-ft) will be required to initially engage the screw in the hole. The maximum tightening torque for these screws is 20Nm (15 lbs-ft). Repeat as necessary for the remaining columns.

3. ATTACH GANGING TUBE TO COLUMNS
   • There are two types of ganging tubes. On the ends of a benching row, close-ended ganging tubes should be used (Type A). Between units, the ganging tubes should be the style that has cord openings on both sides (Type B). Ganging tubes may need to be mixed between kits since the first kit always contains both closeended ganging tubes.
   • Assemble using the M8-1.25 Lock Washer Nut (2 per column). To minimize the number of turns to secure the nuts, the nuts can be threaded on partially prior to adding the ganging tubes. The maximum tightening torque for these nuts is 15.8Nm (10 ft-lbs) A 13mm deep well socket attached to a right angle hex drill adapter is recommended so this step can be done quickly with an impact driver. Repeat steps 1 and 2 for second set of columns, top supports and ganging tube.
   • (OPTIONAL) If support tubes are included, add them prior to tightening the nuts. The T40 bit should work as a substitute for a 6mm allen wrench. Tighten until the metal around the screw begins to flex, this will lock the support tube in place.

4. ASSEMBLE THE CABLE TRAY
   Pre-install (4) of the M8-1.25 12mm self-threading screws onto the ganging tubes, leaving enough gap to slide the cable tray over them and tighten.

5. ATTACH WORK SURFACE
   Top supports should be mounted so that the top supports have equal distance to the left and right edge of the work surface, with at least 3 inches gap between the two work surfaces. Be sure to use approved screws per the table top supplier.

6. ADD ELECTRICAL PARTS TO WORK SURFACE AND FLIP UNIT
   • Before flipping the benching unit, attach the handswitch, control box, and optional gyro sensor to the underside of the worksurface. Use the #10-12 wood screws to attach the pieces.
   • The control box should be placed in-line with the beams of the columns, in an area that can be reached with all motor and switch cables.
   • The optional gyro sensor is recommended to be placed in-line with the columns, near the control box. The cable clamp+screw accessories should be used to hold the power cable in place, and secure dangling cables. Never wrap cables and/or cords around the columns.

  *  **CONNECT THE COLLISION SENSOR TO THE CONTROL BOX INSTRUCTIONS (OPTIONAL)**  

(The sensor can be connected to either the D1 or D2 port of the control box)

  *  **CONNECT THE MOTOR CABLES TO THE CONTROL BOX**
  * The motor cable plug-connection has to click into place.
  * Connections to the control box:  

M1-M2 = Connectors for the columns D1 or D2 = Connectors for the handset

  *  **CONNECT THE HANDSWITCH (HS) CABLE TO THE CONTROL BOX**  

(The handswitch can be connected to either the D1 or D2 port of the control boxer.

  *  **CONNECT THE SUPPLIED POWER CORD (AC) TO THE CONTROL BOX**

  *  **ATTACH ALL CABLES TO THE TABLE TOP**  

Attach cables in order to avoid any damage during operation. Be sure to leave enough slack in the cables to allow for the table to move into it’s highest position. Never wrap cables and/or cords around the columns.

  *  **FLIP UNIT**  

When the electrical components are fixed in place, use two people to flip the unit right-side-up

7. (OPTIONAL) ATTACH ADD-ON UNIT CONNECTION

   • Underneath the ganging tubes of the two units to be connected, use (4) M8-1.25 12mm self-threading screws, leaving enough gap to slip the connector plate on. Shift the units so that the screws align into the keyhole slots, and tighten the screws with the T40 torx bit.
   • Then, drop the connector cover over the plate by inserting the tab of the cover piece into the slots on the connector plate.

8. INSTALL POWER IN CABLE TROUGH
   Electrical Installation

   • INSTALL SIMPLEX RECEPTACLES INTO POWER BLOCK
     Insert terminals into corresponding slots in block and seating receptacle until catches engage on both sides of receptacles. Note: a noticeable “snap” will be heard when receptacle is fully engaged into block. Ensure terminals go directly into slots and do not get inserted into an adjacent slot.

   • CONNECT CABLES TO BLOCK
     Connect as required (not shown). Ensure cables are com-pletely seated under cable latches and into block. Power dis-ruption may occur if cables are not fully seated into block.

  *  **INSTALL POWER BLOCK INTO** TRAY  

Place the power block into the provided cut-out in the tray and slide the block to lock it into place.

  *  **INSTALL U-CHANNEL TO TRAY**  

Power block will wedge into the channel, secure by squeezing the u-channel and locking the tabs into the tray.

  *  **APPLY WARNING LABEL**  

Power block will wedge into the channel, secure by squeezing the u-channel and locking the tabs into the tray.

  *  **For Simplex Receptacle Removal**  

Insert ends of Simplex removal tool into slots above and below receptacle (shown) and push firmly into block until it catches on tool, snap over receptacle edges. Pull receptacle tool and receptacle straight out of the block. Note: Simplex removal tool sold separately.

9. FLIP COVER ASSEMBLY
   • Add the M6-1.0 20mm buttonhead screw, M6-1.0 nyloc nut, and nylon spacer, on only ONE ganging tube (left or right side for both work stations). Tighten using an M4 allen wrench and the 10mm crescent wrench (preferably ratcheting).
   • Once one side is done, gently slip the flip cover over the nylon spacer to act as a hinge on that side. Then, install the screw/spacer/nut on the other side while the first hinge keeps the flip cover in place. Care must be kept not to overtighten the screw and deform the nylon spacer.

OPERATION INFORMATION

INITIALIZATION/RESET

• The desk must be initialized/reset after any of the following:
  • After assembly
  • After disconnection from the power supply
  • After any impact on the table top.
• To initialize/reset, move the table to the lowest position by pressing the DOWN button on the handswitch until the columns reach the lowest position. Press and hold the DOWN button again until the table moves slightly down to the machine zero point and back up to the operation zero point. Release the DOWN button. If the button is released too soon, the table legs will not move up. Repeat the reset process.
• The control box is programmed with a parameter file which controls the table legs’ lower and upper travel limits. Under no circumstance should a control box from one table be moved to another.

NORMAL HANDSWITCH OPERATION (for all handswitch types)
By pressing the UP or DOWN buttons, the table will move up or down to the desired position. Once the desired position is reached, let go of the UP or DOWN button. The table legs will stop once they reach the lower or upper height limits.

PROGRAMMABLE HANDSWITCH OPERATION (optional)

• This programmable handswitch is equipped with a display for showing the current table height in Centimeters or inches.
• The handswitch also will display an error code if an error is detected by the control box. When an error is detected, the display will show an error code “EXX,” instead of the current table height. To resolve the error, see the Troubleshooting Section of this guide.
• The programmable handswitch also has the ability to save up to four different height positions.
• CHANGE THE HEIGHT UNIT (inches or centimeters)
• The handswitch can display the table height in either centimeters or inches. With the help of the F1 menus, the unit of measure can be changed.
• To change the unit of measure, follow these steps:
  1. Press and hold the (Center/—- button) until “F” appears
  2. Using the UP button cycle through the menu for “F1” and press the (Center/—- button)
  3. Choose between “I” for inches or “C” for centimeters and press the (Center/—- button) to select.
  4. To exit the menu without making a selection, wait until the height display appears again.

CHANGE THE HEIGHT DISPLAY
If the displayed value does not match the actual height of the table top, the display can be corrected as follows:

1. Press and hold the (Center/—- button) until “F” appears
2. Using the UP button cycle through the menu for “F2” and press the (Center/—- button)
3. Use the UP/DOWN buttons to adjust to the desired height display and press the (Center/—- button) to save. To exit the menu without making a selection, wait until the height display appears again.

SAVE MEMORY POSITION

1. Move the table up or down to the desired height.
2. Press the center button/—— (in the display “P-” is shown)
3. Select a position by pressing one of the four number buttons, 1-4, (the display will show the setting as “P1”).
4. The saved position is confirmed by a double click sound from the control box. The display shows the current table height. Repeat steps to save a maximum of four different positions.
   To exit the menu without making a selection, wait until the height display appears again.

RECALL MEMORY POSITION
Press and hold the desired memory button (1, 2, 3 or 4) the table moves from the current position into the saved position. The button must be pressed until the position is reached. If the button is released, the table will stop short of the desired height.

SENSITIVITY ADJUSTMENT FOR EXTERNAL COLLISION SENSOR
The sensitivity can be adjusted separately for the optional external sensor (STAND.GUARD G1), each for up and down travel.

1. Go to the menu of the hand switch in accordance with the instructions.
2. Navigate with the arrow keys to the… menu option 8, display shows: F8 for the external sensor (STAND.GUARD G1) drive up or menu option 9, display shows: F9 for the external sensor (STAND.GUARD G1) drive down
3. Confirm the selection by once again pressing the “Logo” key.
4. Use the arrow keys to adjust the displayed sensitivity in % to the desired percentage:
   • 0% (OFF) to
   •  99% (very sensitive)
5. Pressing the “Logo” button again saves the displayed value. Alternatively, wait approx. 10 seconds to cancel the function and to return to the menu.

SHELF AND CONTAINER STOPS
Container and shelf stops are safety positions that cannot be run over during normal operations, so that collisions with known, permanently present hindrances can be prevented. The container stop limits the movement height downwards (minimum height) and the shelf stop limits the movement height of the table upwards (maximum height). If an attempt is made to set the container stop or shelf stop too close to the middle, the controller signals this with 6 quiet click sounds. Note: This function is configuration-dependent and is not available with every controller. With the additional stops, the safety of the table system can be increased, in that the possible movement path is restricted.

SET UP SHELF AND CONTAINER STOPS

• Move the table using the arrow keys into the desired position. Press both arrow keys at the same time.
• The controller confirms with a quiet, double-click. The absence of this signal means that setting is possibly not permitted.

DELETE THE CONTAINER STOP

• Keep the down arrow key pressed. The table stops automatically upon reaching the container stop.
• Press both the arrow keys at the same time. The controller confirms with a quiet, double-click.

DELETE THE SHELF STOP

• Keep the up arrow key pressed. The table stops automatically upon reaching the container stop. Press both the arrow keys at the same time. The controller confirms with a quiet, double-click.
  WARNING: With an initialization movement prompted by the controller, the reset position is always approached directly. Any container stop or safety stop that is present is ignored.

• First, remove all hindrances below the table and pay heed to the increased risk of injury.

• Only trained personnel should carry out setting and deletion of container and shelf stops. There is a danger of injury from wrong setting or removal of the Stop positions, and a danger of the table getting destroyed.

TROUBLESHOOTING
