THE DELIVERY PROCESS There are three basic steps to the delivery process for ICE: Cooling the System Dispensing the Product Ending the Delivery Cooling the System When ICE is powered on, an RTD temperature sensor detects when liquid is present at the pump and begins the Pump Cooling Timer. The timer, which is displayed on the Delivery Mode Screen, counts down from the value entered for the Pump Delay parameter in the System Configuration Mode. If equipped, the Pump Relay is enabled after the timer reaches zero and is disabled whenever gas is detected in the system. Dispensing the Product Once the system has been cooled down, the user should ensure that the ICE is zeroed and ready for dispensing. When the delivery valve is opened, the ICE begins totalizing the liquid flowing through the turbine and the one-minute start phase begins. During the first minute of the delivery, errors are displayed but not recorded in the Trip Log. After the first minute of the delivery, any error occurring more than one minute is recorded in the Trip Log. See section “Error Messages” for a comprehensive list of error messages. Ending the Delivery After dispensing the required amount of liquid, the delivery valve is closed to stop the liquid flow. The delivery remains active until one of the following occurs: A Delivery Ticket has been printed The Delivery Total has been cleared Once the PRINT or CLEAR function is executed, the active delivery ends and the delivery information is recorded in the Trip Log. While a delivery is active, the configuration may be viewed by pressing MODE, however no changes to the configuration are allowed. If an attempt is made to edit a configuration parameter while a delivery is active, the following message is displayed: “Delivery Active. Press CLEAR to exit. Print ticket or clear total to end the delivery” Pressing the CLEAR button removes the message and returns the user to the previous view. Press the MODE button to return to the Delivery Mode and press CLEAR or PRINT to end the active delivery.

PRINT FUNCTIONS Delivery Tickets, Trip Reports, Configuration parameters and the Audit Trail may be printed by connecting an optional serial printer to the RS232 port. The RS232 port settings are listed below and are not user configurable. Handshaking: XON/OFF Baud Rate: 9600 Word Length: 8 bits Parity: None When a print function is requested, ICE checks to ensure that the printer is online and available and that there is paper in the printer. The following messages may be displayed when executing print functions: Message Description Printer out of paper There is no paper detected in the printer Printer offline, no response from printer The printer power is off or the serial cable is not connected between the ICE and printer. Delivery Ticket Press the PRINT button from the Delivery Mode screen to print a Delivery Ticket. This action ends the current active delivery and logs the delivery to the Trip Log. The number of decimal places for the Delivery Total follows the selection for Total Decimal in the System Configuration Mode.

ICE WEIGHT SCALE CALIBRATION PROCEDURE Turbine flowmeters, when properly used, have been found to be more accurate than most weight scales in determining the amount of product delivered. Whenever possible use Hoffer portable Transfer Standard SY-14B to perform ICE system calibrations. This procedure requires the use of two tankers. One full of fresh cold product and a empty tanker. Place the full tanker onto the scales. Hook up the piping so that the full tanker will be pumping off to the empty tanker. Follow the steps below: 1. Power up the ICE unit and enter the MENU. 2. Select CALIBRATION mode. Set K-METHOD to AVERAGE. 3. Record the AVERAGE K-FACTOR value. 4. Select SYSTEM CONFIGURATION MODE. Set DELIVERY UNITS to mass (KG or LB). 5. Return the ICE to the OPERATING mode. 6. Pressurize and cool down the piping and flowmeter. 7. Press the CLEAR key on the ICE twice to clear the total. 8. Weigh the tanker and record its INITIAL WEIGHT. After weighing the tanker start the pump. 9. To determine the TEST SAMPLE SIZE, divide the scale increment by the accuracy requirement. For example, if scale increment is 10 pounds and the accuracy requirement is 0.5%, then 10 pounds / 0.005 = 2000 pounds. It is best to use an accuracy requirement equal to the linearity rating of the flowmeter (typically 0.5%) 10. Open the discharge valve and allow the tanker on the scales to pump off an amount of fluid equal to the TEST SAMPLE SIZE. After the TEST SAMPLE SIZE is pumped, close the discharge valve. Weigh the tanker again, this is the tanker FINAL WEIGHT. Calculate the SCALE TOTAL by subtracting the FINAL WEIGHT from the INITIAL WEIGHT.

11. Record the DELIVERY TOTAL displayed on the ICE. Use the following equation to calculate the new AVERAGE K-FACTOR: AVERAGE_K_FACTORNEW =DELIVERY_TOTAL ________________ SCALE_TOTAL x AVERAGE_K_FACTOROLD 12. Enter the ICE CALIBRATION mode and enter the new AVERAGE K-FACTOR 13. Repeat Steps 6 through 9 to verify the new calibration is within the accuracy requirements. If the new calibration is not within the accuracy requirements then repeat Steps 6 through 12.
