Description of the DESKLINE® DL5/DL6 system
Each DESKLINE® DL5/DL6 lifting units is equipped with a motor and parallel/memory
drive is ensured by means of software in the CBD4/CBD5/CBD6 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® DL5/DL6 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® DL5/DL6 system range contains the following products:
• 1 control box CBD4/CBD5/CBD6
• 1 single DL5/DL6 or 2, 3, or 4 parallel
• 1 exchangeable mains cable
• 1, 2, 3, or 4 motor cables
• 1 DP1U/DPF1M (if memory function is required) DP1C/WDPL/DPT/DPF1C (if
memory function and display is required) or 1 DPA/DPB/DP1K/DP1V/DPF1K (if only
up/down is required.)
Anti-Collision™
The function (anti-collision) is an option for the standard CBD4/CBD5/CBD6 advanced/
control box software 0077432 version 1.66 and later. A system with anti-collision can limit
material damages on a desk if a collision with a solid object should occur
Method of operation
When the DL/DB’s are running the CBD4/CBD5/CBD6 monitors the current
consumption on each channel using a special algorithm. If the current consumption
on one channel is increased more than a predefi ned 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 fi rst 1000 msec or after the control button has
been released
•
If the collision happens between the fl oor 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.
Misc. on the DESKLINE® DL5/DL6 system
This system is a DESKLINE system developed for desks and for indoor use in offi ces. 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 fl oor so that free movement is prevented. This could
cause serious damage to the legs in fault situations.
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 main-
tained 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 fi xing 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/ground-
ing 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 qualifi ed service personnel. Replacement parts for a double-in-
sulated product must be identical to the parts they replace.
The cleaners and disinfectants must not be highly alkaline or
acidic (pH value 6-8).
Electrical connection of the DL5/DL6 system
The DESKLINE® DL5/DL6 system is to be connected as shown on fi gure 4. Each DL5/
DL6 is to be connected to the sockets on the control box by means of the motor cables,
which have an 6-pin plug in each end. 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.
CBD4/CBD5/CBD6 with earth
The CBD4/CBD5/CBD6 earth cable to be mounted on the desk construction (typically the top
frame) in a way that ensures good electrical contact. The function of the earth cable is to earth
the desk and ground static electricity. The earth connection does not protect other electrical
products.
CBD4/CBD5 with mains cut-off (non ZERO models)
If the power cable is damaged it has to be replaced by an authorized LINAK
service centre to avoid any danger.
