1 STAR-700 Operating Guidelines with 25 Segment Programmer. Safe Operating Value (SOV). On initial Power up the STAR-700 Touchscreen shows the Main Screen and controls the Safe Operating Values only. You will notice that the indicator in the top right corner states that the Program Cycle is OFF. The Values below the heading Safe Operating Value are the current set values and the controller will start to control these values. To change the Safe Operating Value simply touch the Operating Value box. A Pop-Up numeric keypad is displayed. Type in the new value and press enter. The cabinet will automatically control the new Safe Operating Value. The Safe Operating Value has been designed to be set by the operator to a safe/normal condition that will not cause damage to any Research, Experimental, Plant Material and/or any items being stored in the cabinet in the event of a power failure. If a Program Cycle is operating and a power failure occurs, on resumption of power the controller will revert to its Safe Operating Values. Main Menu Screen (SOV Mode)

2 Main Menu Screen with Pop-Up Numeric Keypad. Humidity ON/OFF Function. After setting the Safe Operating Value the operator may need to check whether they require the Humidity Control to be ON or OFF. Touch the drop down list arrow (Located below the Humidity ON/OFF Indicator at the bottom right of the Main Screen ) and turn the Humidity ON or OFF as required. When the Humid Function is ON and controlling, the Indicating box will be green and scroll the message Humidity Control ON. If the Humidity Control is OFF the indicating box changes to red and scrolls the message Humidity Control OFF. Note that the Safe Operating Value for humidity can still be changed and the Actual Humidity Value is still displayed, although the Humidity function is OFF.

4 Program Set-Up. The STAR 700 has a 25 segment Programmer. By pressing the Program Set-Up the Program Screen is displayed. The below information shows a description of each parameter and how it performs. Segment Type: Jump To: Jump Cycle: Temperature: Humidity: Co2: Hours: Minutes: Seconds: The segment type can either be a Time, Jump To, or End type. Time: This determines that the segment is a period of time. The time is set in Hours, Minutes and Seconds. Jump To: This allows the program to repeat a predetermined set of segments. By selecting the Jump To parameter in segment type and then entering a segment value at the Jump To parameter, will tell the program were to jump back to. At Jump Cycle enter how many times it jumps back to or repeats the predetermined set of segments. See Example on next page. End: This tells the program when to end. There has to be an end segment. Failure to enter an end segment will cause the controller to indefinitely dwell at the last segment. The operator would enter the segment number that the program will jump back to. The operator would enter a value here as to how many times the Jump To repeats itself. A value of 0 will continually repeat the Jump To segments until the operator ends the Program Cycle manually. The operator would enter the Temperature they require the cabinet to achieve. The operator would enter the Humidity they require the cabinet to achieve. The operator would enter the Co2 they require the cabinet to achieve. The operator would enter the required length of time for the segment in Hours. The operator would enter the required length of time for the segment in Minutes. The operator would enter the required length of time for the segment in Seconds. Event Outputs (Optional). At each segment page there is an events button. By pressing this button the display shows Eight events that can be turned ON and OFF for each segment. If the Events option is not taken this page is still displayed and will function correctly. There is simply no Hardware to turn ON and OFF as part of a program cycle. Program Features. There are a few other features of the program that cannot be changed but are described below. Guaranteed Soak: Program Start Value: Power Failure: This is a tolerance value, set at +/-2.0degC, and guarantees that the Program Set Values for Temperature only are reached. If during a program cycle the Actual Temperature deviates the Program Set Value (PSV) by more than +/- 2.0degC the program will be put into a hold mode until the Actual Temperature is within the PSV. There is no Guaranteed Soak on the Humidity Value or the Co2 value. These values can deviate without the program going into a hold mode. The Program starts at whatever the Actual Temperature, Humidity and Co2 are. If when starting the program the Actual Temperature is more than +/- 2.0degC from Segment 1 s PSV the Guaranteed Soak value will hold the program until it reaches Segment 1 s target temperature. In the event of a power failure the Program Cycle will end. On resumption of power the cabinet will control the Safe Operating Values.

5 Program Set Up Screen Example (Segment 1-5). The above screen shows an example of a simple five segment program cycle. When starting the Program, assuming the actual temperature and Humidity is at 25.0degC and 65%RH (the SOV), the cabinet will take two hours to reach its first target of 10.0degC and 60%RH. The second segment will hold the 10.0degC and 60% for 10hours. The third segment will repeat segment 1-2 three times. This will basically hold the 10.0degC and 60%RH for 46hours. The Temperature, Humidity, Co2, Hours, Minutes, and Seconds Values for Segment 3 are ignored as the segment Step Type is set to Jump To. Once it repeats Segment 1-2 three times it will ramp from 10.0degC and 60%RH to 25.0degC and 60%RH over 10 Hours. The Program will then end and control the Safe Operating Values (SOV).

7 Starting the Program Cycle. To start the program, return to the Main Screen. Touching the Main Screen button on any page will go back to the Main Screen. Once back at the Main Screen the top right corner shows the Program status indicator this should be Red and scrolling the message Program Cycle OFF. To start the Program Cycle simply touch the drop down list arrow and select START. The program status indicator will change to Green and Scroll the message Program Cycle Operating. When the program is operating the operator can pause the program by selecting PAUSE in the drop down menu. The Program status indicator will remain Green but the scrolling text will change to Program Cycle Paused. To resume the program back simply select RESUME from the drop down menu. To stop the Program Cycle simply select END from the drop down Menu. Main Menu Screen (SOV Mode). Showing Program Status Values. Main Menu Screen (SOV Mode). Showing Program Status Values.

10 Data Menu By pressing the Data Menu Button the image below is displayed. On this screen Data can be retrieved for archiving purposes. Insert a USB Memory Card into the USB port at the front/side of cabinet. Keep watching the screen for the following message USB Disk/SDMMC Card Plugin Once this message has been viewed the operator can press the Download Data to USB button. The Red Indicator will flash whilst data is being downloaded to the USB Memory Card. When the Red Indicator stops flashing it is safe to remove the USB Memory Card. The length of time it takes to download the data will depend on how much data is being downloaded. If the memory is full, then the download period could be quite long. If the downloaded files are kept on the USB Memory card the download time is shortened as it only updates the latest files not present on the USB Memory Card. Data is downloaded as a Comma Delimited File. This data can be imported into Microsoft Excel. When importing data make sure that the date format is set for YMD (Year-Month-Day). Every 24hrs the Data Log Menu screen is refreshed. The Data that is downloaded to the USB Memory Card is downloaded in files that represent every 24hrs. The data in the table is refreshed every 24hrs. However the data in the memory that can be downloaded will store approximately 800 days. Data Menu Screen.

11 Security Screensaver, Passcodes & Blank Screen. The Touchscreen is fitted with a Security Screensaver to stop unauthorised access to the controlling parameters.
