Danger: Never open the housing of the control unit or the hand switch.
Unauthorised opening and improper repairs could result in dangers for the user, and the entitlement to
guarantee claims shall be null and void.
Only the qualified technicians of the manufacturer are authorised to open or repair the electrical

2. Functions and features

The desk system Contec-plus is exclusively intended for indoor use as office furniture in the commercial sector.
The hand switch of the desk serves as the control of the electrically powered, height-adjustable desk system.
The basic function is to raise and lower the desktop.
Advanced functions are to store height positions, and to move to these positions (memory control).
During commissioning, an initialization (manual reset) must be carried out (see section 3.3).
This will normally be carried out by the qualified technician of the specialized dealer/manufacturer during assembly
and commissioning at the installation site.
In the event of a power outage while the drives are operating, another reset must be carried out, before the desk can
be used normally again.
The reset movement will be performed at a reduced speed.
The movements of the drives are electronically monitored by the control unit. On exceeding the maximum duty cycle,
the electronics will prevent any further travel of the drives in order to protect the electrical and mechanical components
against overload.
In the event of unacceptably high temperatures, a shutdown will occur.
In this case, the LED display on the hand switch will blink, when pressing the keys.
The maximum duty cycle is 2 minutes, after which the control unit is automatically disabled for the next 18 minutes.
If the control system detects excessive weight loads it will also be automatically disabled.
The maximum distributed load of the desk is 70 kg.
The maximum noise emission during movement of the desk is 50dB(A).
After starting and before stopping, the drives will temporarily run at a reduced speed (soft start/soft stop).
A certain zone (ca. 40 mm before the lower end position), is defined as a safety area. If the drives reach this point, a
safety stop will be triggered. After pressing the key again, movement will be resumed at a reduced speed.
If a desk meets an obstruction when moving downwards, the internal collision protection system will prevent a tilting
position and stops the desk from toppling over. If an obstruction is detected, a safety function is triggered and the
desktop automatically moves a defined distance in the opposite direction.
Danger:
In spite of the collision protection system in place, there may still be a risk of pinching in exceptional cases.
For physical reasons „soft" obstructions are difficult or impossible to detect and evaluate. In the event of a
collision with an obstruction, damage occurring to the obstruction cannot be ruled out.
