Repairs
In order to avoid the risk of malfunction, all DESKLINE®repairs must only be carried
out by authorised LINAK workshops or repairers, as special tools must be used and
special gaskets must be fitted. Lifting units/lifting columns under warranty must
also be returned to authorised LINAK workshops.
Warning!
If any of the DESKLINE products are opened, there will be a risk of
subsequent malfunction.
Warning!
The DESKLINE®systems do not withstand to cutting oil.

Misc. on the DESKLINE®system
Warranty
There is a 36 months’ warranty on the DESKLINE products against manufacturing
faults from the production date of the individual products (see label).
LINAK A/S’ warranty is only valid in so far as the equipment has been used and
maintained correctly and has not been tampered with. Furthermore, the system
must not be exposed to violent treatment. In the event of this, the warranty will be
ineffective/invalid. For further details, please see LINAK A/S ordinary conditions of
sale.
Maintenance
Clean dust and dirt on the outside of the system, at appropriate intervals and
inspect them for damage and breaks.
Inspect the connections, cables and plugs and check for correct functioning as well
as fixing points.
The cleaners and disinfectants must not be highly alkaline or acidic
(pH value 6-8).

1 or 2 DL2 lifting column(s) (no memory or parallel drive)
1 Control box CBD2
1 DP (Desk Panel)
1 Exchangeable mains cable
(With mains cut-off the cable is not exchangeable)

Mounting guidelines for DL2 with CBD2N control box
The DL2 column is supplied with either 8 mm end plates or 3 mm end plates.
8 mm end plates:
For mounting on the desk frame there are 4 holes for M10 bolts. It is
recommended to use all 4 bolts.
3 mm end plates:
For mounting on the desk frame there are 4 holes in the column for DG 80 x 35
screws. It is recommended to use all 4 screws.
As the table top amplifies the sound we advise you to place a vibration/shock-
absorbing material between the table top and the table frame.
The outer profile of the DL2 column has tracks, which can be used for mounting a
bracket. The mounting bracket can be used for e.g.:
Mounting a customised cover (for encapsulation of the DL2).

To limit the influence from the bending moment it is recommended to place the
heaviest load in the shaded area (see figure 2) in which the spindle is placed. The
spindle part is placed in the same side as the cable outlet.
See the DL2 data sheet for further information regarding bending moment.

Mounting guidelines CBD2N
The CBD must not be packed in heat insulating material, but must be placed so
that it can emit waste heat into the surroundings. There are no ventilation holes to
consider, the CBD emits heat through the surface.
The plug must be visable when the CBD is mounted so that the supply to the CBD
can be disconnected at replacement, if any.
The mounting screws on the control box must be fastened with a max. torque of 1
Nm.
The mounting surface, to which the control box is attached, should have a surface
evenness of max. ± 0.5 mm.
For mounting and operation of the desk panel, please see the separate user
manual for desk panels.
CBD2N - Control box
The control box is to be fastened with 4 screws
with a head diameter between ø 8 and ø 10 mm.
Out of regard for the tension surface ø 10 mm is
preferable.
See drawing appendix for placing of mounting
holes and the space the CBD takes up.

Electrical connection of the DL2 system:
DESKLINE system with a CBD2N which is not built into the DL2:
The DESKLINE®system is to be connected as shown on figure 3. The DL2 is to be
connected to the socket on the control box by means of the motor cable,
which is supplied with an 8-pin plug. The connection of the DL2’s are on the
same side of the control box.
See figure 3.
Finally the mains cable is to be mounted and power switched on.
Please note that the control box must only be connected to the voltage
stated on the label.
Be careful that the plugs are fixed exactly above the counterpart before
pushing them together. Otherwise the plugs may bend and following errors
may occur:
The lifting units will not run as there is no current
The lifting units cannot find the end-stop positions
In the worst case the switches in the control box will short-circuit, which will
damage the CBD2.
The control (DP) is to be connected to port B on the control box - the
opposite side of the DL2 column (see figure 3).
The connection is made by a 8 pole modular jack plug.
Up to 2 SLS (Safety Limit Switches) can be connected to the control
box on the opposite side of the lifting units. The connection is made
by DC mini jack plugs (see figure 3).

Operation with SLS
The CBD2N supports two SLS (Safety Limit Switch) inputs. The switches must be
type NO (normally open). The SLS can optionally be connected to the SLS input.
Each SLS input controls one function. The function is stated by choice of CBD2N.
Below functions are possible:
1 input, CH1 down
2 input, CH1 and CH2 down
1 input, CH1 up
2 input, CH1 and CH2 up
2 input, CH1 up and down
2 input, CH1 down and CH2 up
When SLS is activated the movement will stop immediately. It will not be possible to
drive in the opposite direction until reactivating the control.

Description of the DESKLINE®DL2 Memory System with CBD2
E/F/G
The DESKLINE®DL2 Memory system contains the following products:
1, 2 or 3 DL2 lifting column (s)
1 Control box CBD2
1 DP Desk Panel
1 DPA/DPB Desk Panel
1 Exchangeable mains cable
(With mains cut-off the cable is not exchangeable)
Options:
Built-in control box (CBD)
Class 1 protection (not if built-in CBD)
Prepared for 1 or 2 anti-squeeze safety switches
(NO type = normally open), only stop (not if built-in CBD)
It is possible to run extra actuators (LA31 with hall) (not if built-in CBD)
Description of the DESKLINE®DL2 system
Each Deskline lifting unit DL2 is equipped with a motor and memory drive is
ensured by means of software in the CBD2. CBD2 also has soft start, which ensures
a soft start when adjusting the desk.
Application of the DESKLINE®DL2 system:
Irrespective of the load the duty cycle 5% ~ 3 min./ hour or max. 1 min. at
continuous use stated in the data sheets, must NOT be exceeded as this will result
in a overheating of the motor, the brake and the spindle nut. Exceeding the duty
cycle will result in a dramatic reduction of the life of the system.

Mounting guidelines for DL2 System
The DL2 column is supplied with either 8 mm end plates or 3 mm end plates.
8 mm end plates:
For mounting on the desk frame there are 4 holes for M10 bolts. It is recom-
mended to use all 4 bolts.
3 mm end plates:
For mounting on the desk frame there are 4 holes in the column for DG 80 x 35
screws. It is recommended to use all 4 screws.
As the table top amplifies the sound we advise you to place a vibration/shock-
absorbing material between the table top and the table frame.
The outer profile of the DL2 column has tracks, which can be used for mounting a
bracket. The mounting bracket can be used for e.g.:
Mounting the control box.
Mounting an extra actuator for tilt function of the table top.

To limit the influence from the bending moment it is recommended to place the
heaviest load in the shaded area (see figure 6) in which the spindle is placed. The
spindle part is placed in the same side as the cable outlet.

The control box is to be fastened with 4 screws

Electrical connection of the DL2 system:
DESKLINE system with a CBD which is not built into the DL2:
The DESKLINE®system is to be connected as shown on figure 10 and 11. The DL2
is to be connected to the socket on the control box by means of the motor
cable, which is supplied with an 8-pin plug. The connection of the DL2’s are on
the same side of the control box. See figure 10.
Be careful that the plugs are fixed exactly above the counterpart before
pushing them together. Otherwise the plugs may bend and following errors
may occur:
The lifting units will not run as there is no current
The lifting units start to run but stop due to lack of pulses
The lifting units cannot find the end-stop positions
The system cannot be initialised and therefore it cannot find its memory
positions.
In the worst case the switches in the control box will short-circuit, which will
damage the CBD2 (see figure 10).
The control (DP/DPA/DPB) is to be connected to port B on the control
box - the opposite side of the DL2 column (see figure 10). The
connection is made by means of a 6 or 8 pole modular jack plug. Up
to 2 SLS (Safety Limit Switches) can be connected to the control box
on the opposite site of the lifting units. The connection is made by
means of DC mini jack plugs (see figure 10).
Finally the mains cable is to be mounted and power switched on.
Please note that the control box must only be connected to the voltage
stated on the label.
