5 General Overview The RC 2 refrigeration controller is a second-generation component of Novar s Spectrum Advanced Refrigeration Control System. The RC 2 controls the refrigeration system by executing a highly developed, advanced control strategy and by monitoring the various refrigeration system functions and system components (compressor racks, refrigerated display cases, condensers, etc.). The RC 2 can be configured so that it acts as the central access point to the refrigeration control system from the actual site or a remote location such as the facility s home office, or it can function as part of the facility s larger local-area network (LAN). It automatically maintains the operation of the refrigeration system without any user intervention. Some of the RC 2 s features include: Automatic power-up/power-down mechanisms with dual watchdog protection and built-in diagnostics Two-part construction (wiring base and electronics are separate and plug-in) Plug-in backward compatibility with older facility installations (fits existing plug-in wiring base) Multiple LAN and module communications strategies for installation flexibility: Unit-to-unit Ethernet LAN RS-485 LAN (Master/Slave, Mod2, NovarNet ) Phase-loss detection and control strategy Direct unit access (Ethernet only) Refrigeration control during reconfiguration Multiple built-in control strategies: Automatic Compressor Staging User-Defined Compressor Staging Circuit/Defrost Control Condenser Control Universal Analog Output Control Float Control Annunciator Multiple Alarms Compressor Alarms Case Management Systems Multiple built-in communications mechanisms: One 10/100 Base-T Ethernet port One Hayes-compatible 56k bit/second modem One RS-485 LAN communication port Three RS-485 control module communication ports One RS-232 local access port DOC. #TD /12/07 1

6 Extensive alarm strategies: General purpose user-definable alarm settings Extended user-definable alarm settings (including event counters and triggers) Historical alarm event logging Automatic remote alarm reporting Remote alarm monitoring (client or Web access) NOTE! The RC 2 is programmed in Novar s Engineering and Support System (ESS32) software. In the software screens, executive modules such as the RC 2 are referred to as units. External Browser Support The RC 2 includes an embedded Web server (user-configurable port) that can be accessed by various Web browsers (Internet Explorer 5.X, Netscape 6.X, etc.). The Web server serves the same pages that are available to the internal touchscreen (which is driven by an embedded internal Web browser). The following procedure can be used to access RC 2 Web pages from an external browser. NOTE! If a user attempts to edit settings, the browser will ask for an appropriate user name and access code. The RC 2 disregards the user name one does not have to be entered in the dialog box. An accurate access code is required. Step Procedure 1 Start the Web browser. 2 Insert the cursor at the right end of the URL address (Figure 1) and backspace to delete the existing URL. 3 Type in any one of the following URLs, substituting the RC 2 s IP address for Press enter or click Go.

Flash memory is accessed (it s reading load change information). 55 seconds or more: The RC2 is fully loaded and starts its control strategies. Power-Down Sequence When the RC 2 loses power, it goes through a power-down sequence to shut down in an orderly fashion. The exact sequence used depends on how the RC 2 is configured. It can be configured one of the following ways: RC2 is not configured to report a Power Failing alarm. RC2 is configured to report a Power Failing alarm via Ethernet. RC2 is configured to report a Power Failing alarm via modem. The sequence used for each of these configurations is described below. NOTE! LEDs are identified by numbers in the following sequences. To determine their location on the RC 2, see Figure 3. Several of the steps in the sequences refer to the Modem Status Indicator LED. Operation of this LED is dependent upon the existence of an internal modem. If the RC 2 is not equipped with a modem, the LED does not turn on. 10 DOC. #TD /12/07

15 RC 2 Not Configured to Report Power Failing Alarms When power is removed from an RC 2 not configured to report power failing alarms, the following sequence takes place. 0 5 seconds: The Internal Flash Memory LED (#3; see Figure 3) blinks while the load change configuration image is written to internal flash memory. The Modem Status Indicator LED (#4) turns off. The Ethernet Good Link LED (#6) turns off. The touchscreen display turns off. The RC 2 is now off. RC 2 Configured to Report Power Failing Alarms via Ethernet When power is removed from an RC 2 configured to report Power failing alarms via Ethernet, the following sequence takes place. NOTE! The timing in this sequence assumes that the alarm will be reported by this RC 2 to a single alarm receiving station. If the RC 2 is configured to report alarms to an alternate unit or multiple alarm receiving stations, the timing will be different seconds: The amber Ethernet LED (#7) flickers while reporting the power failing alarm seconds: The Internal Flash Memory LED (#3) blinks while the load change configuration image is written to internal flash memory. The Ethernet Good Link LED (#6) turns off. The touchscreen display turns off. The Modem Status Indicator LED (#4) turns off. The RC 2 is now off. DOC. #TD /12/07 11

The timing in this sequence assumes that the alarm will be reported by this RC 2 to a single alarm receiving station. If the RC 2 is configured to report alarms to an alternate unit or multiple alarm receiving stations, the timing will be different seconds: The internal modem goes off-hook and dials the remote reporting phone number. Once connected, the modem reports the alarm. The internal modem hangs up the phone seconds Killing the RC 2 Download The internal flash memory LED (#3) blinks while the load change configuration image is written to internal flash memory. The Ethernet good-link LED (#6) turns off. The touchscreen display turns off. The Modem Status Indicator LED (#4) turns off. The RC 2 is now off. Under various conditions, the installing contractor might want to return the RC 2 to its basic, unloaded state. The Killing the RC 2 Download procedure is used to accomplish this. This procedure completely erases the contents of the internal flash memory module by quickly formatting the module. Once the procedure is completed, the RC 2 is ready to receive a download. CAUTION! Once this procedure is completed, the RC 2 will not control any devices or report any alarms until it has been reloaded. Proceed with extreme caution. NOTE! This procedure applies to files residing on the internal flash memory. It does not affect the RC 2 settings (network address, touchscreen lighting, etc.) configuration in EEPROM. Once the RC 2 download has been killed, it will operate according to the EEPROM configuration settings. 12 DOC. #TD /12/07

If this is set to Ethernet, the LAN baud rate does not apply. LAN baud rate the LAN (RS-485) communications speed. Send alarms for dial out to unit directs alarms to the desired unit for remote reporting. Send alarms for local print to unit directs alarms to the desired unit for local printing. NovarNet Continuous Mode enables or disables the NovarNet continuous mode. Continuous mode removes a 6-second delay (per minute) on the RS-485 LAN system that is required for some installations. The delay is typically not required on most installations NovarNet reconfig count is a real-time count of the number of times the NovarNet token passing system has automatically reconfigured itself. This value counts from time of download or time of power-up. continued 34 DOC. #TD /12/07
