9.37 Standard Circuits
Refrigerated cases that do not use case controllers are
controlled by Standard Circuit applications. In a Standard
Circuit application, the Supervisory Controller is responsible
for all case monitoring and control; it uses the RS485 I/O
Network to both gather case temperature inputs and activate
or deactivate the liquid line solenoids, defrost modes, and
fans. Also, circuits that use ESR8s and MultiFlex ESRs are
controlled using Standard Circuits.
The Standard Circuits application provides supervisory
control of controllers. It keeps the temperature setpoint and
other basic configuration parameters synchronized across all
associated devices.
How To Add a Standard Circuits Device on the
Supervisory Controller:
1. From the Home screen, navigate to Main Menu>
Summaries and Floor Plans> Site Summaries>
Refrigeration, click the screen drop-down arrow on the
upper right of the screen, click Add Controls.
2. Select the Control or Application Type - Circuits
(Standard), enter the Quantity, Control Name and Serial
Type. Note that Serial Type information can be enter
later. Click Save to add the application.
3. A Confirmation box will appear saying that the
application is successfully added to the system, click
Close or Edit these controls.
4. The system will display the new application(s) on the Site
Summary screen.
5. Click the Standard Circuits application panel box to view
the application.
6. The system will display the Standard Circuits application
parameters.
7. The user can view and configure the properties of the
application by setting the Edit Mode to ON on the screen
drop-down arrow on the upper right of the screen.
Licensing:
The maximum number of Standard Circuit applications that
can be licensed is 48.
Open Associations

9.38 Case Control Circuits
9.38.1 Overview
Case circuits that use CC-100s, CS-100s, EC-2s, or CCBs for
case control rely on Case Circuit Control applications in the
Supervisory Controller to provide them the necessary
setpoints, defrost scheduling, and other control parameters.
Unlike Standard Circuit applications, Case Control Circuits do
not directly control temperature in the case circuits; instead,
the case controller controls temperature for each individual
case based on the setpoint(s) supplied to them by their
associated Site Supervisors.
Setup of a case-controlled refrigerated case system is a two-
fold process:
1. For each case circuit in the refrigeration system, a
separate Case Control Circuit application is
created with its own set of control parameters.
2. Each CC-100, CS-100, EC-2, and CCB is associated with
a Case Control Circuit application in the Supervisory
Controller. Association creates a network link between
the case controller and the application which supplies
the information necessary to control temperature,
defrost, lights, fans, and anti-sweat heaters.
This section of the manual covers both the programming of a
Case Circuit Control application and the process of
associating a CC-100, CS-100, EC-2, or CCB with a Case
Circuit Control application.
NOTE
NOTE: Do not set up a Standard Circuit
application for a case that uses a CC-100 or CCB
case controller. These cases must use Case
Circuit Control applications.
