Required checks
When the
Locked
position can no longer be shown, always conduct the fol-
lowing checks before unlocking:
•
Carefully retract and extend the telescoping cylinder or telescopic section
In the
Locked
position, the length shown on the displays (
1
) should vary only
slightly, i.e. by the play of the locking pins.
Retracting
The steps for retracting are the same when an error occurs on the proximity
switch as for an error on the length indicator.
– When the display (C) fails:
•
Calculate the telescoping cylinder length for the locking point;
Locking points for the telescoping cylinder
•
Move the telescoping cylinder to the required length – display (
1

Risk of damage if the length specifications are not observed
Extend the telescoping cylinder (without telescopic section) only to the
specified length.
This prevents the piston rod from becoming damaged if the telescoping
cylinder slides out of the telescopic section.
