Detailed procedures
The following sections provides detailed information about the setup procedures for the A5xx Controller.
Setting up the A5xx Controller
To set up the A5xx Controller, set the physical components and features of the controller in the system setup
screens. The selections and values that you enter in the system setup screens define the physical characteristics
and operation of the refrigeration system on the controller. The following figure shows the order for setting up the
controller. It is best practice to configure the system setup screens first to define your refrigeration and defrost
system in the controller.
• The gray setup screens on the following pages are conditional screens. The selections you make in the system
setup, defrost setup, UI setup, and alarm setup screens determine the presence of these conditional screens.
The conditional setup or status screens appear on the LCD only if you require the conditional screen to set up
your application or view your application status.
• After you define the system setup parameters in the controller, the setup screens that do not apply to your
selections become unavailable. You cannot interact with these setup screens when you set up the cooling and
defrost parameters.
• The controller ships with factory default selections and values already entered in the system screens. In most
applications, you must change the factory default selections and values to meet the specific refrigeration and
defrost requirements of your system.
