User’s Manual
A mechanical bottom obstruction device switch
permits the bottom obstruction device to be still
operational during manual descent. Manual descent
will be stopped if an obstacle is encountered.
3.6.14 Top obstruction device
Top obstruction device interrupts ascent if it
encounters an obstacle. Descent will still be possible,
for instance to remove the obstacle.
When the top obstruction device switches
are engaged, press the down button until it
disengages.
Do not use the service lift until the top
obstruction device switch fault has been
rectified.
3.6.15 Top limit switch
Top limit switch interrupts ascent if it is triggered by
the top plate.
Emergency top limit switch is triggered in case the
top limit switch fails to engage. It cuts off power
supply, so only manual descent will be possible.
Top limit plate is mounted on the ladder.
In Octopus L95 these switches can be located
on the top of the cabin, beside safety and
traction wire ropes. The top limit plate will be
attached to traction and safety wire ropes.
3.6.16 Manual descent system
The service lift features a manual descent system
that can be used in case of emergency.
To activate it, push the manual descent actuator
fully upwards. The electromagnetic motor brake is
released.
The service lift descends with a controlled speed
limited by means of a centrifugal brake installed
between the motor shaft and the gear box.
3.6.17 Overload limiter
An overload limiter is built into the traction hoist. In
case of an overload, it will prevent the upward travel
and a buzzer will sound, until overload condition is
eliminated.
Attempting to run in an overloaded liiff is
prohibited!
Performing a manual descent in case of an
overloaded lift is prohibited!
