Procedures During Normal Running
(Assumption: The turbine is running normally)
•
No operating procedures are required. Take every opportunity
to visually observe the system in operation and to listen for
any unusual noise. This is always a good practice.
Procedures for Stopping and De-activation
IMPORTANT NOTE: A stopped turbine will still yaw and align to follow
the wind. A braked machine although stopped, can still cause serious
injury to personnel. The machine must be fully secured before
approaching and must only be approached in calm or very light wind
conditions.
(Assumption: The turbine is to be stopped and electrically isolated)
•
Procure the brake “T” bar and approach the tower base.
•
Verify that the brake ratchet mechanism is engaged.
•
Insert the “T” bar into the brake and wind the handle a little to
verify the ratchet operation.
•
While observing the turbine, slowly wind the brake handle until
the brake tension is detected and the turbine slows down to be
stationary.
•
Wind the handle two more “clicks” and remove the brake
handle.
•
At the interface module, operate the stop switch S1 and pull
out (disengage) the turbine fuses F1/F2.
Procedures for Routine Maintenance
Routine maintenance is described is Section 7.0 of this manual. The
same start and stop procedures are used for maintenance.
The tower brake “T” bar must be removed to prevent accidental brake
release and to “Lock out” the turbine brake.
