Misc. on the DESKLINE®DL4S system
This system is a DESKLINE system developed for desks and for indoor use in offices. Do not use it in industrial kitchens or in
other enviroments that have to be cleaned with aggressive detergents.
Do not bolt the legs to the floor so that free movement is prevented. This could cause serious damage to the legs in fault
situations.
Warranty
This DESKLINE product is subject to warranty pursuant to the terms of LINAK DESKLINE Warranty Paper, available on the LINAK
website www.linak.com/warranty.
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.
Service of double-insulated products:
Class II
A Class II or double insulated electrical appliance is one which has been designed in such a way that it does not require a
safety connection to electrical earth (US: ground).
The basic requirement is that no single failure can result in dangerous voltage becoming exposed so that it might cause an
electric shock and that this is achieved without relying on an earthed metal casing. This is usually achieved at least in part by
having two layers of insulating material surrounding live parts or by using reinforced insulation.
There is no earthing/grounding means provided on the product, and no earthing/grounding means is to be added to the
product.
In Europe, a double insulated appliance must be labelled “Class II”, “double insulated” or bear the double insulation symbol (a
square inside another square).
Servicing a double-insulated product requires extreme care and knowledge of the system, and is to be done only by qualified
service personnel. Replacement parts for a double-insulated product must be identical to the parts they replace.
The cleaners and disinfectants must not be highly alkaline or acidic (pH value 6-8).

Description of the DESKLINE®DL4S system
Each DESKLINE®DL4S lifting units is equipped with a motor and parallel/memory drive is ensured by means of software in the
CBD6S (SMPS) that also takes account of oblique load on the desk. Soft start and stop are also part of this software, which
ensures a soft start and stop when adjusting the desk.
Application of the DESKLINE®DL4S system:
Irrespective of the load the duty cycle 10% ~ 6 min./ hour or max. 2 min. at continuous use stated in the data sheets,
must NOT be exceeded as this will result in a superheating 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.
The DESKLINE®DL4S system range contains the following products:
• 1 control box CBD6S 200W or CBD6S 300W (SMPS - Switch Mode Power Supply)
• 1 single DL4S or 2 in parallel
• 1 exchangeable mains cable
• 1 or 2 motor cables
• DP1U / DPF1M (if memory function is required) or DPT / DPF1C / DP1CS (if memory function and display is required)
or DPA / DPB / DPH / DP1K / DP1V / DPF1K (if only up/down is required) or DPF1D (If display is required)

Mounting guidelines for DL4S
Placement of a monitor directly above the leg may cause malfunction of the monitor. Magnets inside the motor
may interrupt the picture on the monitor depending on the distance and the type of monitor. If this is the case, the
problem may be solved by placing an iron plate/tube or another magnetic material, somewhat larger than the DL4S,
between the motor and the desktop.

Height of the DL4 in the lowest position

Min. B + 10 mm
Max. B + 15 mm
B
The mounting of the bottom part is analogue to the top part shown
A suitable desk height in the lowest position can be obtained by mounting the lifting unit on a 6-8 mm bottom plate by means
of 4 pcs. of M6 countersinked screws.We recommend you to use screws of min. quality 8.8. The thrust moment must not
exceed 10 Nm in the top and bottom plate thread.
The mounting bracket for the crossbar is mounted on the largest profile. The cable is led out at the top of the small profile.
This means that the column must always be mounted with the largest profile downwards.
Cable handling
Before mounting the DL4S to the table top, please lead the cable through the small plastic cable handler (see the blue part on
the drawings below).This is to avoid squeezing the cable between the table top and the column during mounting because of
misplacement of the cable. By guiding the cable through the cable handler, the cable will be securely fastened, which eases the
mounting of the column.

CBD6S 200W and CBD6S 300W
Mounting guidelines CBD6S (SMPS)
The control box is to be fastened with 2 screws with a head diameter between ø 8 and ø 10 mm. Out of regard for the tension
surface ø 10 mm is preferable due to lower surface tension. See drawing appendix for placing of mounting holes and the space
the CBD takes up.
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 visible 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 better than ± 0.5 mm.
Bottom with cable grooves
The bottom of CBD6S (SMPS) is equipped with two cable grooves improving the cable management when mounting. The
grooves can be used to bypass the CBD for both motorcables and the mains cable (EU version only) from one side to the other,
giving a cleaner design.
Remember to lead the cables through the grooves before mounting the control box.
For mounting and operation of the desk panel, please see the separate user manual for desk panels.

Anti-Collision™
The function (anti-collision) is an option for the standard CBD6S (SMPS) control box. A system with anti-collision can limit
material damages on a desk if a collision with a solid object should occur.
Enabling the anti-collision
To enable the anti-collision function a little plug called a dongle must be mounted in one of the 2 control ports. The function is
only active when the dongle is mounted. – If you remove the dongle again you disable the function.
Method of operation
When the DL/DB’s are running the CBD6S (SMPS) monitors the current consumption on each channel using a special
algorithm. If the current consumption on one channel is increased more than a predefined slope, a collision is assumed and all
channels are stopped immediately and all DL/DB’s will start to run in the opposite direction (approx. 50 mm). This return drive
is done automatically and continues with or without any control key pressed (for max. 2.5 sec.).
The anti-collision sensitivity is different in upward and downward direction. Upwards the force is approx. 20 kg. Downwards
the load will be approx. 40 kg + the load on the DL/DB (the desk + what is on top of the desk). The 40 kg are needed to
activate the anti-collision function.
Situations where the anti-collision does not work
There are situations where the anti-collision will not be activated. These situations are:
• If the collision happens during the initialisation phase
• If the collision happens within the first 1000 msec or after the control button has been released
• If the collision happens between the floor and the table and the load on the desk + the weight of the legs are lower than
40 kg
• If the collision happens over too long time, e.g. if the collision is with a soft object.

Disposal of LINAK’s products
As LINAK’s customers often ask us how our products can be disposed or scrapped we have prepared this guidance that
enables a classification to different waste fractions for recycling or combustion.
Guidance
We recommend our products to be disassembled as much as possible and divided into different waste groups for recycling or
combustion.
For example, waste can be sorted into metals, plastics, cable scrap, combustible material, and recoverable resources.
Some of these main groups can be further divided into subgroups; e.g. metal can be divided into steel/aluminium/copper and
plastic can be divided into ABS/PA/PE/PP.
As an example, the table below breaks down the different components in LINAK products to various recycling groups:
Product Components Recycling group
