HP-319 12 ICE Quick Start Guide

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.

HP-319 13 ICE Quick Start Guide

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.

INSTALLATION GUIDELINES

 ICE should be installed with enough clearance to allow easy

access to all cables. Care should also be taken to install ICE
away from thawing pipes to minimize direct contact with
moisture.



Do not over tighten the mounting bolts. The recommended
tightening torque for the shock mounts is 105 lbs-in.



Hoffer recommends powering ICE directly from the truck
battery. The DC+ power line may be wired through an external
switch if desired, or ICE may be ordered with an optional power
switch installed.



Hoffer recommends grounding the ICE enclosure to the trailer
chassis using the provided ground strap (part #100-2733) for
improved immunity to ESD (electrostatic discharge) and EMI
(electromagnetic interference).



Refer to the installation drawings located in the back of this
manual for wiring information.

ICE WEIGHT SCALE

CALIBRATION PROCEDURE

HP-319 36 ICE Quick Start Guide

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.

HP-319 37 ICE Quick Start Guide

11. Record the DELIVERY TOTAL displayed on the ICE. Use the

following equation to calculate the new AVERAGE K-FACTOR:

AVERAGE_K_FACTOR

NEW

=

DELIVERY_TOTAL

________________

SCALE_TOTAL

x AVERAGE_K_FACTOR

OLD

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.
