Operation
Controllers
Controller redundancy
The Frame system uses dual master controllers: a main Module and a redundant Module. The
controllers are identical and monitor all Modules and external user interfaces. Only the acting
master sends execution commands to Modules. The main controller sends the redundant
controller a message periodically indicating its health. If the redundant controller has not
received a message for a consecutive number of periods it will assume the role of master
controller and generate a controller fault alarm. The redundant Module will return control to the
main Module when the redundant Module receives health messages from the main Module.
Module controllers
Module controllers are connected via CAN to each other and to the main and redundant
controllers. Data collected by the Module controllers is sent to the master controller.
Display Interface
Remote display interface panel
The remote display interface enclosure houses a display that is used to control the EcoBreeze
from a remote location. The master controller communicates with the remote display interface
via CAN.
