Annex 5 Speed control for rotary heat exchanger
5.1
Speed control
The cabinet with the speed control system for the rotor is installed behind the inspection door.
The cabinet contains the speed controller with all components, terminal blocks, LED displaying the operation mode, the
dual position DIP switch with 8 sliding levers for programming the rotor motor signal and a button for the activation of
the test mode.
Through the different combinations of the 8 sliding levers of this dual position DIP switch, the correct signal is available
for the 2 different motors used for the 7 sizes of Geniox Core air handling units. The sliding levers are set and the
function is checked at the factory. The positions of the levers appear from the tables below.
