Trapped-Key Interlock System; Slack Rope Sensor; Anchor Points - Avanti SHARK L AECO Original Instructions Manual

The fences remain closed and locked until the service
lift is stopped and properly positioned on the platform,
actuating the position switch of the platform. In this
position, the guard locking can be unlocked while
pressing the green light button.
The interlock control box has a main switch. Turn the
switch to the OFF position to cut the power to the
service lift. The main switch must be set to OFF when
the lift is not in use, when leaving the wind turbine and
while the wind turbine is running. It must be set to OFF
before starting an electrical generator.
Consult the AVANTI Guard Locking System Manual
for further information.

5.8.2 Trapped-key Interlock System

The Trapped-key Interlock System uses a system of
security locks installed on the fences. These locks can
be opened by using a key placed into the lift.
The key also activates the On/Off general switch
placed into the service lift cabin. The key is linked to
the lift by means of a wire rope, and cannot be
detached from it except using cutting tools.
The key cannot be taken out from the On/Off general
switch in the lift, unless it is in Off position, and
therefore, the lift is stopped. In the same way, the key
cannot be taken out from the fence lock unless the
fence door is closed, and the door actuator is put into
the door lock.
The fences remain closed and locked until the service
lift is stopped on the platform, and the key is trans-
ferred from the lift cabin to the fence lock.
Consult the AVANTI Trapped-key Interlock System
Manual for further information.
