Indicating lamps
The top lift has a set of three indicating lamps for container han-
dling:
A. Green left: TWIST-LOCKS LOCKED
B. Orange middle: ALIGNMENT
(The lamp will be extinguished at lifted container)
C. Red right: TWIST-LOCKS UNLOCKED
Alignment control
A spring-loaded contact pin and an inductive sensor at each
twist-lock is used for alignment control. The top-lift is fully aligned
onto the container when all pins have been depressed and the
distance between each pin and sensor have decreased to 4–5
mm. Then the indicating lamp ALIGNMENT lights up and the
twist-locks are ready for locking.
Safety interlocking system
After locking of the twist-locks the lifting starts. A built in play be-
tween twist-locks and container corner boxes allows the attach-
ment to be lifted enough for the inductive sensors to be
deactivated, i.e. the distance between sensor and contact pin in-
creases to more than 8 mm.
This will brake the minus feed to the twist-lock solenoid valve,
thus making it impossible to operate the twist-locks when lifting.
This electrical interlocking can, in emergency situations, be
bridged by an override switch in the operator’s cab. The override
switch will feed ”false” alignment minus signal to the twist-lock so-
lenoid valve thus making it possible to operate the twist-locks. A
red warning lamp lights up in the operator’s cab when the electri-
cal interlocking is bridged.
Checking of ALIGNMENT indicating lamps and
electrical interlocking system
1. Check that the contact pins in the corner boxes are freely
moveable up and down. A pin which binds in the upper posi-
tion may indicate correct alignment although the top-lift is not
in contact with all four container corners.
2. Check that the indicating lamp ALIGNMENT lights up when
the top-lift is fitted to the container and that the lamps are ex-
tinguished when the container is lifted.
3. When lifting an empty container just enough to make the lamp
ALIGNMENT go out, check that it is impossible to unlock the
twist-locks.
4. The sensor 7202/7203 for alignment should be adjusted to
give a signal when the contact pin is depressed 3-4 mm.

WARNING!
Whenever the indicating lamps do not work properly, the
attachment should be taken out of service for repair. The
use of an attachment with faulty indication lamps could
be hazardous!
