Initial Operation
On first use of the system and in case of
error it is necessary to restart the system by
following the steps given below.
First installation / initialization of the drive
system:
• If there is an audible signal (simple BEEP)
when the function buttons UP or DOWN
are pressed, the system is ready for use
but the position of the actuators is either
unknown or more than 5mm apart.
• Press and hold the DOWN button (rear
button on the right or left armrest) until
the actuators begin to move.
• Now press and hold the button again
until the actuators have reached the lower
end position.
• Next press and hold the UP button (front
button on the right or left armrest) until
the lifting columns have moved approxi-
mately 5cm upwards.
• Then press and hold the DOWN but-
ton again until the lifting columns have
reached the lower end position again and
the control system has switched off both
drives.
• The drive sensors are now aligned.
• The system is now initialized and can be
put into operation.
“Position Lost” during operation:
• If the system is overloaded or there is a
height difference between the actuators
of 5mm or more, the system stops.
• When the function buttons UP or DOWN
are pressed, a BEEP is heard.
• The system must be initialized. Follow
the instructions given in the section “First
installation / initialization of the drive
system”.
Failure to operate / control error / Fatal
Error Reset:
• In the event that the system fails to func-
tion and it is also not possible to reinitial-
ize the actuators, there could be a control
software error.
• In this case, the control system software
can be reset to its former state prior to
the occurrence of the error through a so-
called “Fatal Error Reset”.
• To carry out the Fatal Error Reset, press
and hold both function buttons (UP and
DOWN) for approximately 20 seconds.
• During the reset a double-BEEP will be
heard. After this sound has subsided the
reset is successfully completed.
Attention!
If the system is unable to be operated
after both initialization and a Fatal Er-
ror Reset, please contact our customer
service.
