3-Pole Run/Stop Switch (GA-CTRL-008A)
Only operate in light winds
Introduction
Please read this manual thoroughly before attempting to assemble, install or operate your run/stop
switch. This will assure optimum performance and safety.
The run/stop switch is designed to allow the user to dynamically brake the LE-600 wind turbine at
will. This is achieved by disconnecting the power output of the turbine from the relevant load and
diverting it to a short circuit which then applies the dynamic braking effect on the permanent
magnet alternator of the turbine. This will bring the turbine to a near stop for maintenance only.
The run/stop switch can be used with turbines of different manufacture as long as the relevant
turbine has the following characteristics:
3-phase Wild AC not exceeding 150 V & 20 A
Mechanically and electrically capable of dynamic braking
Operation & Specification
The run/stop switch should be operated during low speeds as repeated use at high speeds may
cause damage if the turbine head (it was not designed to withstand repeated dynamic braking
operations).
The switch has two positions:
Position 1: Turbine 'Stop' position. The turbine is dynamically braked and may rotate very slowly.
Position 2: Turbine 'Run' position. The turbine output is allowed to flow straight through the switch.
