Note: General Market cabinets require the cabinet to be set up via the SKOPE-connect app,
which the store owner or manager will have access to. Check to see if they have it on their
device.
SCS Setup is only available in certain roles. If your role requires regular access to this
procedure and you do not have access, contact SKOPE.
Linking an SCS controller to a refrigeration cabinet is a key part of allowing accurate data to
be gathered for review and service assistance.
Select the appropriate owner and the brand.
The cabinet owner should always be set to SKOPE – this should
come pre-set from the factory. The brand is the corporate customer
who is using the cabinet. This is not set at the factory before
delivery and must be set before placing the cabinet into the market.
The list of available brands will appear once the cabinet owner has been set. Ensure you
select the correct brand at this stage as an additional reset process will be required if it is set
incorrectly.
When the owner and brand are successfully set, you can add the key details of the cabinet.
IMPORTANT

SKOPE SCS Connect Electronic Controller
Application Procedures
Technicians’ Manual
Track App
The AoFrio Track app for mobile devices transfers data from SKOPE equipment using the
SCS Connect controller to a cloud-based server.
The app works automatically in the background. When the app detects a controller, it
connects via Bluetooth to receive data from the controller and send data to the cloud. If no
mobile data connection is available, the app stores data until a connection becomes
available.
SKOPE recommends that all technicians who service SKOPE equipment fitted with the
AoFrio SCS Connect electronic controller have the AoFrio Track app installed on their
Bluetooth-enabled mobile device. All technicians are also required to have the AoFrio Field
app installed on their Bluetooth-enabled mobile device.
The app is passive and runs in the background (it can track automatically). When servicing a
cabinet, open the app to ensure tracking has finished before you start servicing.
Bluetooth must be on to perform a manual scan with the Track
App. Open the App and press the Scan or Connect Now
button.
Data from the cabinet will be downloaded into your device and
then uploaded to the cloud for future analysis.
Note: “Download completed” does not mean that the data has
been uploaded to the cloud. The upload process requires data,
and will be automatically completed when data coverage is
available.

16 Faults and Alarms
Technicians’ Manual
SKOPE SCS Connect Electronic Controller
3 Faults and Alarms
If a fault occurs, it is logged, the Fault - Alarm indicator is lit on the controller faceplate, and a
message may be displayed. Faults do not affect product temperature, and do not require
action from the shop owner, unless they turn into an alarm.
If an alarm occurs, it is logged, the Fault - Alarm indicator is lit, and the alarm message is
displayed on the controller faceplate. Alarms may result in abnormal product temperature.
Some faults and alarms can be cleared by the shop owner, and others can only be cleared by
a service technician. Faults and alarms can be cleared by the shop owner by power-cycling
the cabinet. However the fault or alarm will only clear if the problem has been fixed. If the
problem still exists after a power-cycle, a service technician will need to fix the problem.
