4. Description of the product

Warning

Risk of injury!

The end product may present further, previously

unforeseeable hazards.

Warning

Risk of injury!

Despite a number of software based protective

guards there is still a

risk of getting crushed in exceptional cases as

motor shutdown is not only governed by the

control unit but also by the interaction of the

mechanical and electronic components!

Shutdown sensitivity is also influenced by the

mechanical components, motor and ambient

conditions!

For this reason, the manufacturer cannot entirely

rule out this residual risk and does not accept

any liability!

i

Note

You will find a detailed description of how to use

the listed functions in the following sections.

7. Operation

7.5.5 Plug detection

The control unit detects whether a lifting column is plugged in at

a specific socket. The control unit also detects whether a lifting

column has been changed.

If a lifting column is missing or has been replaced, the control

unit clicks three times. The display also shows a fault code (see

list of faults in Section 8) if the handset has a display.

A manual reset must be performed to rectify the fault, (see Sec-

tion 7.4.4 for further details).

7.5.6 Auto detect number of drives

Besides plug detection, the control unit can also automatically

detect the number of lifting columns plugged in. This feature is

always active during first startup of the control unit and after

returning the control unit to factory settings (see section 7.5.9).

Lifting columns plugged in after the first startup of the control

unit will not be detected automatically. For changing the estab-

lished configuration the control unit has to be returned to factory

settings.

Possible situations:

· The control unit is being used for the first time

· The control unit has been returned to factory settings

7.5.7 Collision detection (Drive back)

The desk top automatically changes its position by a defined dis-

tance in the opposite direction after triggering a safety function

(through collision detection ISP or optional accessory, e.g. crush

guard). This prevent parts of the body from being permanently

trapped.

i

Note

The drive back function is only active if a collisi-

on detector (ISP or optional accessory, e.g. switch

or crush guard) is available.

Warning

Warning!

In spite of ISP collision detection there is still

a risk of getting crushed in exceptional cases

as motor shutdown is not only governed by the

control unit but also by the interaction of all

components of the electrically height adjustab-

le workstation! Deactivation sensitivity is also

influenced by the mechanical components, motor

and ambient conditions!
