Emerson E2 operation manual Logging Groups, Setting Up An Individual Case Controller

case controller has no usable case temperature input value), the case controller will keep the valve percentage at its last known good value and continue operation as nor- mal. For instance, if the valve was at 75% when the case temp sensor(s) failed, the valve will remain at 75% until it the failure is corrected. All other case control functions will continue functioning as normal.

11.4.12 Wiring

Input and output wiring for a case controller is dis- cussed in detail in Section 4, E2 Hardware Setup. Before a Case Control Circuit application may begin functioning, all case controllers must be properly connected to its case inputs and outputs, and each case controller must be com- missioned and properly communication on the Echelon Network (see Section 4, E2 Hardware Setup for instruc- tions on how to do this).

11.4.13Setting Up An Individual Case Controller

Most of the data required for a case controller to begin operation are supplied to it by associating the controller with an E2. However, in some cases, it will be necessary to change some of the parameters in an individual case con- troller. Some instances where it will be necessary are:

•When the configuration for the inputs needs to be changed (i.e., when the case has a sensor or switch configuration that cannot be satisfied by the default configuration).

•When a valve other than an Emerson Flow Con- trols ESR-12, ESR-20, or ESV is being used. Each case controller is programmed by default to operate Emerson Flow Controls brand valves. If the valve type is different, the valve control parameters must be changed in the case controller software.

•When the PID settings that determine the valve aperture or closure require alteration.

When necessary, the case controller can be altered in either of two ways. You can change settings in a case con- troller application in E2 via the front screen. Or, you can use a Hand-held Terminal to log in to the CC-100 or CS- 100 directly, and make temporary changes that will not be saved.

11.4.14Associating Case Controllers with Case Circuit Control Applications

Before you can program a Case Control Circuit with the necessary parameters, you must associate the appropri- ate CC-100s, CS-100s, EC-2s, and CCBs with the Case

Control Circuit application you will be programming.

To access the CC/CS-100 Case Control Association Screen:

1.Press for the Main Menu.

2.Press for System Configuration.

3.Press  for the Network Setup menu.

4.Press  for Case Control Associations. The

Case Control Association screen should look like Figure 11-7:

Figure 11-7- CC/CS100 Circuit Association Screen (RX-400)

This screen lists all of the CC-100s, CS-100s, EC-2s, and CCBs defined in this E2. Each one is listed with its name, its node number, the application name of the case controller’s application, and the associated circuit name.

To associate a case controller with its circuit, move the cursor into the Circuit field of the controller you wish to associate, and press the  key. The Application Selec- tion menu will list all of the Case Control Circuit applica- tions in the E2. Choose the desired circuit and press  or  to select. Repeat this process until all case con- trollers are associated with Case Control Circuit applica- tions.

11.5 Logging Groups

A logging group is a set of application property inputs and outputs whose values are recorded (logged) with the same parameters. Parameters include the interval, how often the property values are logged (for example, every 30 seconds, every 5 minutes, etc.), the duration of the log (for example, 2 days, 30 days, 100 days, etc.), and the res- olution (how precisely the analog values are recorded).
