Emergency Stop Buttons
For safety reasons please note the location of the 4 emergency stop buttons. The buttons are located
(Figure 1 Locations of emergency stop buttons and trip F60 in nacelle) at:
•
Ground controller (at the bottom of the turbine).
•
Gearbox (pos. 1).
•
Yaw ring (pos. 2).
•
Nose cone (pos. 3, only local stopping function)
•
Nacelle controller (pos. 4).
•
Trip F60 (pos. 5).
The emergency stop buttons are red with a yellow background. An emergency stop is activated by
pressing one of the red buttons. When an emergency stop is activated, the controller switches to
“EMERGENCY STOP” mode meaning that no power will be supplied to the contactor solenoids, the
blades will pitch (full feathering), the brake will be applied and the turbine will stop. The yaw system,
the hydraulic pump, the gear oil pump and the nacelle ventilator will also stop. Consequently, all
moving parts will be brought to a standstill.
However, the power supply to the light, the nacelle, the hub and the ground controllers will still be on.
The stop button in pos. 3 is not an emergency stop button but a local stopping function.
