7. Life phases
7.5 Adjustment without power (can be extracted)
All activities described in this chapter must be carried out without loads.
7.5.1 Description
By the adjustment without power, the linear movement of the electric cylinder can be carried out by
hand without using the drive motor.
The adjustment without power is required in situations where a quicker change in the position has
to be carried out. For example, with a quick low position of hospital beds or an adjustment in event of
power failure.
7.5.2 Function and procedure
The push rod is released from the drive motor by actuating the Bowden cable. One or two
Bowden cables can be mounted on the electric cylinder.
•
Before the Bowden cable is pulled, the push rod must always be relieved
first.
The push rod is not secured against being pulled out completely when
actuating the Bowden cable!
A respective safety precaution, such as a stop, must be guaranteed by the
user of the drive.
•
•
•
Relieve the electric cylinder. Then release the push rod by pulling on the Bowden cable
(approx. 8 mm). Keep holding the Bowden cable.
Without the electric cylinder drive, move the load to the desired position.
Let go of the Bowden cable. The push rod is coupled again.
•
•
The stroke of the cylinder originally set is not changed when using the Bowden cable.
The adjustment force required on the push rod after releasing using the Bowden cable is different
depending on the configuration of the Lambda electric cylinder:
Version 1: approx. 300 N
Version 2: approx. 200 N
Version 3: approx. 80 N
