4.3.3 Optional analog output (0 – 10 V)
The integrated analog output supplies information about the movement and cur-
rent position of the connecting rod to the control unit.
The analog output is electrically isolated from the limit switch electronics of the
device and therefore requires a separate voltage supply of 24 V DC.
The output voltage increases linearly to extend the connecting rod.
The output voltage of 0 – 10 V relates to the maximum stroke.
The screening must be applied by the customer.
4.3.4 Safety nut option
WARNING
Danger of injury through loss of the support and holding function.
Persons may be crushed and killed.
•
Operation with the device with supporting safety nut must be stopped.
•
After activation of the supporting function of the safety nut, the device must
be shut down immediately.
A safety nut is used, in particular, where damage could result following a break-
age of the supporting thread.
If the thread turns in the supporting nut fail (e.g. wear limit exceeded), the safety
nut takes over the support and holding function.
Device operation must not continue in this state because the safety nut is also
subject to natural wear.
We recommend therefore that the wear status be checked at regular intervals,
e.g. after 8000 m operational performance of the device (Compakt 15 kN pull-
push load with observance of all technical parameters) by the manufacturer to
prevent hazardous situations.
Engagement of the safety nut can be indicated by squeaking of the device, a
sudden change in the end limit position or running of the motor without a stroke
movement.
Devices with safety nuts are classified as low-maintenance because a check
should take place after the above-mentioned operational performance.
