Product Description
The Smith AccuLoad II Sequential Blender is a four
component microprocessor-based electronic
preset/blending delivery system designed to
sequentially control the loading of up to four petroleum
or chemical products through each of two separate
load arms simultaneously.
The AccuLoad II is designed to provide dependable
service over a wide range of operating conditions. It is
easy to operate and maintain, provides optimum
measurement accuracy, display of current operating
conditions, is easy to communicate with, and performs
many loading system control functions.
Ease of operation and service permits rapid training of
operators and service personnel. All entries into
AccuLoad II are made quickly and easily through the
rugged external keypad. Every keystroke is monitored
and assistance is provided by auto prompting displays.
Built in "Help Messages" provide valuable information
to aid in the programming of the instrument without
resorting to a thick manual. Service is simplified with
self-diagnostics that show parameters in need of
adjustment or hardware that is malfunctioning.
Optimum measurement accuracy is attained through
the continuous linearization of the meter factor with
changes in flow rates. The AccuLoad II is also
capable of maintaining back pressure on the
measurement system using either automatic flow
optimization or a pressure transmitter. Volumetric
correction is calculated directly from published API
equations providing precise volumetric measurement
results. Precise temperature, pressure compensation,
and density correction are options that are available in
the instrument.
The dynamic real time display of the current actual
operating conditions of the system provide the
operator with valuable system information while the
system is operating. Also available through the
dynamic display are the non-resettable totals for each
position. The information that is available through the
dynamic display is as follows:
• Current Time and Date
• Current Flow Rate (units/min.)
• Current Flow Rate (units/hour)
• Current Temperature
• Current API
• Reference Density
• Relative Density at Reference

The AccuLoad II, if so programmed, will automatically
calculate and adjust the additive pulse output to be
stopped at the first trip point of the product with the
same number of pulses as if the additive output were
stopped at the end of the batch***.

Section 1 - Introduction
2MN06053 Rev. 0.4 5/96
Significant communication capability is available from
the standard AccuLoad II. The instrument is
programmable for Polling, Polling and Authorization or
complete Remote Control via communications. The
EIA-232 communication port can be used to multi-drop
up to 32 meter positions to an ASCII printer for printing
load tickets or it can be used to network up to 32
meter positions to an automation system. Also
available is an additional communication port that is
EIA-485 interfacable. When used with a smart printer;
one that will signal when it is out of paper, cover is
open, etc., the AccuLoad II can alarm and display the
reason for the printer not working. The "speak when
spoken to" protocol of AccuLoad II is modeled after
the ISO Standard 1155. This allows quick access by
an automation computer for operational and
transaction information. The AccuLoad II also has a
built-in communication analyzer to aid in the
development and troubleshooting of communications.
For additional information on the AccuLoad II
communications, see the Communications Manual
(Bulletin MN06055L).
The AccuLoad II Sequential Blender provides several
loading system control functions: Additive Injection,
Pump Control, Alarm Control, Set Stop, Valve
Control, Back Valve Control, Back Pressure Control,
Automatic Adjustment of Final Trip Point.
•Up to seven different additive injectors can be
simultaneously paced or controlled through
communications per preset position.
•The AccuLoad II will monitor and totalize the
volume of additive injected by up to seven of the
additive injectors if the additive monitoring option
is purchased.
•AccuLoad II, if so programmed will automatically
calculate and adjust the additive pulse output to be
stopped at the first trip point of the product with
the same number of pulses as if the additive
output was stopped at the end of the batch.
•A contact is available to start and stop a pump or
other electrically operated equipment as well as a
program code that will set the time delay of that
start or stop.
•A programmable Alarm Contact is available. It can
be closed on a Valve Fault, on any alarm or not at
all depending on how it is programmed.
•The AccuLoad II contains the intelligence to
control a Smith Model 210 or 215 Digital Control
Valve which will provide low flow start and multi-
stage shut-down.
•Up to four product block valves can be controlled
(opened and closed) and sequenced by the
AccuLoad II Sequential Blender. The unit will
monitor these block valves to ensure that they
respond to signals sent to them. If for some
reason they do not respond, the AccuLoad II will
alarm and shut the system down.
•AccuLoad II contains the intelligence to
automatically reduce the flow of product and
ensure the flow is within the pumping capabilities
of the system.
•AccuLoad II, if so programmed, will automatically
adjust the final trip point of the batch (Preset).
Critical functions such as: minimum flow rate, excess
flow rate, temperature detection, preset volume
overrun and memory retention, are monitored by
internal circuits. Any failure will signal closure of the
valve. Should the valve fail to close within 10 seconds
after having been signaled, a contact is closed. This
can be wired through external relays to shut off the
pump and/or kill power circuits.
Environmental fluctuations within specified limits have
virtually no effect on the operation of this control
system. AccuLoad II is available in an explosion-proof
housing for hazardous locations. (See Bulletin
SS06014 for Specifications.)
How To Use This Manual
This manual is to be used as a guide for AccuLoad II-
SEQ firmware.
This manual is divided into five sections: Introduction,
Operations, Dynamic Displays, Program Mode and the
Program Codes.
"Operations" describes the daily operation of
AccuLoad II and what is required of an operator to
effectively load the product.
"Dynamic Displays" describes the information that can
be displayed by AccuLoad II while in the "READY"
state or in the Run Mode.
"Program Mode" describes how to get into the
Program Mode, Program Directory Selection, Program
Code Selection, how to change a program parameter
and how to view the Help Messages.

Section 1 - Introduction
MN06053 Rev. 0.4 5/96 3
"Program Codes Section" gives an outline description
of each program code available in the instrument. For
a brief description of each code, the information or
options required for each code, and a place to record
the parameters entered in each preset position see
Bulletin AB06030. For detailed information on each
code see Bulletin MN06054L.
The examples presented in this manual are for clarity
and your convenience. The values might vary for your
particular installation and/or operation.
Before Beginning Operations
Before actual operations begin, it is essential that valid
entries are made for all program codes. To assist in
programming the AccuLoad II, a programming
workbook (Bulletin AB06030) is available for recording
the values entered in the program for each preset
position. Access to the program codes is limited to
authorized personnel by use of a security code and
two contact closures. The first contact closure will
allow the operator to view all program codes and
change the program codes that have a second digit of
zero through three. The second contact closure is
required to change the program codes that have a
second digit of four through seven. This additional
security is for Weights & Measures purposes. A
program code with the 2nd digit of 8 will be
programmable in either the Program or Weights and
Measures Protection Mode. Any program code with a
second digit of nine has a special high-security
protection. This requires the second contact closure
and an external jumper must be attached to test points
9 and 10 on the computer board.
The AccuLoad II contains two side by side one line by
24 character, 5X7 dot matrix vacuum fluorescent
displays. When powered-on, both displays will
illuminate. The left-hand display (preset position 1) will
show if the status of the internal memories (Ram,
Data, ROMs) are good or bad. Then it will show that
the instrument is being initialized. The right-hand
display (preset position 2) will display the message
"PLEASE STANDBY". After the testing is complete
and the instrument is initialized, both displays (preset
position 1 and preset position 2) will read as follows
before the Ready Mode message is programmed in
the instrument:
Ready 1:10:31
Be sure that AccuLoad II is functioning properly and
that the operator has read and understands the
instructions contained in this manual.

Section 2 - Operations
4MN06053 Rev. 0.4 5/96
Run Mode
This is the normal driver controlled mode of operation
where a preset volume of product is preset into
AccuLoad II. The flow is then initiated, controlled, and
stopped by AccuLoad II at the end of the batch.
All preset and control operations can be performed
either locally through the keypad or through
communications. The operation described in this
section is based on AccuLoad II being operated locally
through the keypad. For information on operating
through communications refer to the AccuLoad II
Communications Manual.

Keypad Functions
The pushbuttons on the keypad perform the following
preset functions in the Run Mode:
’0’ - ’9’ Used for presetting the quantity to be
delivered.
’CLEAR’ Used to clear incorrect entries and to exit
from the dynamic displays.
’ENTER’ Used for dynamic displays and selecting
the recipe required for loading.
’PRINT’ Signals completion of transaction when
"Print Key" option is selected in program
code 301 of the Systems Directory.
’SET’ Used to initiate the preset sequence and
sequencing through recipes.
’START’ Used to start the delivery (providing all
external permissive senses are satisfied).
’STOP’ Used to stop the delivery at any time.

Section 2 - Operations
MN06053 Rev. 0.4 5/96 5
Overview
The "RUN" Mode for each preset position permits the
operator to select the recipe, the preset volume and
start the preset volume or to observe the dynamic
variables such as flow rate, temperature, volume
correction factors, transaction totals and non-
resettable totals. Normal start-up, flow control and
shut-down sequences, along with operator requested
stops, will be independent for each preset position.
Preset volumes can not be entered simultaneously to
both preset positions since the numeric keypad is
shared by both preset positions. In any mode of
operation with AccuLoad II, the data entered through
the numeric keypad is assumed to be associated with
the last preset position function key pressed. For
example; if the ’SET’ button is pressed for preset
position 1, any keypad data entered will be assumed
to be for preset position 1 until the next function button
is pressed.
Product delivery is controlled by several program code
entries made for each preset position. Functions such
as: first high flow rate, second high flow rate, low flow
start, first and second trip points will be automatically
controlled and monitored per their program entries.
Safety and volume accuracy functions such as;
excess high flow, low flow, overrun and temperature
probe failure are also monitored per their program
values. If at any time an alarm occurs while in the
Ready State or the Run Mode, AccuLoad II will
attempt to shut-down the flow and a message
indicating an alarm condition will alternate with the
current display.
When the delivery is completed, the display will read:
Preset Completed
Depending on how AccuLoad II is programmed, the
transactions for the preset position used could be
ended by removal of the ticket from the ticket printer,
pressing the ’PRINT’ button associated with that
preset position, or by a communication command. If
the ’STOP’ button for the preset position is pressed
during flow, and if the STOP/START delay is
programmed, the preset position will display:
100 Restart in 5
Where 100 is the volume of product that has been
delivered and the 5 is the number of seconds (that
have been programmed in code 206 of the Systems
Directory) before the operator can restart the batch.
Once the time-out has been reached, the display will
then read:
Press Start to Continue
The operator can then press "START" and continue
the batch. If program code 206 is programmed to
disable the time-out, the display will read:
Press Start to Continue
as soon as the operator presses "STOP". Then it will
alternate with the preset display.
Meter Position Disabled/Not Installed
The AccuLoad II will contain the necessary software
and hardware to operate two meter positions. This
may be confusing to an operator if only one of the
meter positions is currently connected and operating.
For this reason program code 190 of the Systems
Directory can be programmed to disable the meter
position not currently connected or in use. This
program code will be under the High-Security Mode.
When selected, the meter not in use will display the
following message:
Meter Position Not Used
If the AccuLoad II has been purchased as a single
preset position, either preset position #1 or preset
position #2 can be programmed as the operating
position. The display on the preset position not being
used will display the following message:
Meter Position Not Used
Note: The position programmed must match the position that has
been wired as the operating preset position.
Remote Start/Stop
Two permissive sense contacts can be programmed in
AccuLoad II that can be used for Remote
Start/Remote Stop operations (codes 806 and 810).
To use these permissive sense contacts as Remote
Start or Remote Stop, hardware jumpers must be
installed on the keypad and computer boards in the
proper position for correct operation. When ac power
is applied to the contacts, AccuLoad II will respond as
though the ’START’ or ’STOP’ button has been

Section 2 - Operations
6MN06053 Rev. 0.4 5/96
pressed. (See the Installation Manual MN06037 for
jumper positioning).
Quad OPV
The optional Quad OPV is a hardware option that
provides one additional dc output for each preset
position. This output can either be used as a relay
output or a pulse output for an additive injector, remote
counter, etc. If used as a pulse output, the pulse rates
and type of pulses are programmable in the 300
subdirectory of the Systems Directory. The pulse
rates are programmable between 000.1 units per pulse
and 999.9 units per pulse with a maximum frequency
of 500 Hz. The programmable options for the type of
pulses are Raw, Gross, GST, Net and Mass.
Additive Monitoring
The additive injector feedback option provides the
capability of the AccuLoad II monitoring the additive
products that are being injected. The AccuLoad II
monitors the injector feedback switches for a change
of state and counts the errors and alarms if no change
is detected within a programmable period.
Note: See program codes 841 through 863 of the Systems Directory
for programming the additive feedback option.
Master/Slave Communications (Rev. 13 and above
firmware
A new feature has been added. Revision 13 firmware
has been designed with a Master/Slave type of
communications, with the AccuLoad II being the
master and the Additive Injector System being the
slave. The AccuLoad II constantly interrogates the
Additive Injector System for a change in status. The
AccuLoad can be operated with communications
control over the Smart Additive Injector System or with
communications/pulse control. When the AccuLoad II
has communication control over the Additive System,
it will constantly monitor the Additive System for its
status, poll the additive totals, and signal the system
when to inject the additive - all through the
communications line.
If the AccuLoad II is programmed for
communications/pulse control, two lines have to be
run between the Additive System and the AccuLoad II
- one for the product pulses and one for the
communications line. In this case, the AccuLoad II will
constantly monitor the Additive System for its status
and poll the additive totals. It will not signal the
Additive System when to inject additive; this is done by
the Additive System counting the pulses and injecting
at the rate programmed by the AccuLoad II.
The AccuLoad II communications package has also
been designed with a pass-through communications
mode. In this mode of operation the supervisory
computer can talk to the Additive Injector System
through the communication lines that have been run to
the AccuLoad II and from the AccuLoad to the Additive
Injector System(s).
Additive Injector Selection
Stand-alone Mode
When the AccuLoad II Sequential Blender is in the
Stand-alone Mode of operation the additive selection
can be programmed to be either automatic or manual,
depending on how code 803 of the Systems Directory
has been programmed.
Code Description
803 Manual/Auto Additive Injector Option must be
programmed to either:
Zero for auto injectors - the additive outputs
that are programmed in the AccuLoad II will
automatically be selected for each batch.
One for manual injectors in the Standby Mode
only at the beginning of each transaction.
Two for manual injectors prompting at the
beginning of each transaction.
Three for manual injectors prompting at the
beginning of each batch.
The operation will be as follows for manual selection
(code 2 or 3):
1. Select Recipe.

Indicating which of the additive outputs have been
selected. If none of the additives have been selected
the display will read:
No Injectors Selected
Note: If the selections are incorrect press "CLEAR" and the original
display will be displayed (see step 1) and the process can begin
again.
Note: Any additive output that has a zero entry programmed in its
corresponding program code will always be disabled and will not
appear in the selection process.
Note: Additives selected manually will override the additives that are
programmed in the recipe that is being loaded.
8. Once the driver or operator verifies that the
additives that have been selected and are
displayed in step 4 are correct press ‘ENTER’.
The display will light up momentarily and then go to
the preset display.

same as described in the Stand-alone Mode (see
above).
Automated Proving Mode (Rev. 12 and above
firmware
A feature has been added to the AccuLoad II-SEQ
firmware that provides an automated proving mode of
operation. When the automated proving mode is
activated the AccuLoad will calculate the meter factor
for a proving run based on information that is obtained
during the prove. The operator can select the flow
rate and meter factor that is being proved through the
keypad of the AccuLoad. After the prove is complete
the operator enters the prover volume and prover
temperature and the AccuLoad will calculate the new
meter factor and the operator has the choice of
downloading it to the program or to ignore it. The
AccuLoad also has the capability of providing an
average meter factor over a maximum of six proves.
This feature allows the operator to prove the meter on
all four products, and four meter factors and
associated flow rates for each product without having
to enter the program mode for each product and meter
factor.
Entry to the Automated Proving Mode will require
several conditions to be met.
1. The Automated Proving Mode must be enabled via
code 359.
2. The program contact must be open.
3. The Weights and Measures Contact must be
closed since it is possible for the meter factor to be
altered. Then when normal conditions are met for
starting a transaction (pressing the "SET" key or
receiving authorization via communications), the
Automated Proving Mode will be activated.
4. To initiate the proving sequence, the AccuLoad II
will prompt for the prover coefficient of cubical
expansion. Note that the most recent value for this
entry will be displayed. If this value is acceptable,
the operator need only press ’ENTER’.
Prover Coeff 0.0000186005.
5. The AccuLoad II will prompt for the low flow start
volume. If low flow start is not desired, enter zero.
Note that the low flow start rate used will be the
one already entered in the Program Mode. Press
’ENTER’.
Low Flow Start 000 Gal

Section 2 - Operations

6. Next, the AccuLoad II will display the select
recipe prompt. If in remote control
communications mode, only those recipes
allocated will be available for selection.
Select Recipe
Note: If the recipe selected is not a single-product recipe,
"Proving requires single-product recipes only" will be displayed.
Press ’SET’ until the desired recipe appears or key in
the recipe number. Then press ’ENTER’.
7. The operator must next select the meter factor and
associated flow rate for proving.
Prove for Factor 1,2,3,4
Enter a "1", "2", "3", or "4" for the meter factor
associated flow rate that is required. Note that
only those factors currently programmed will be
offered as selections. Press ’ENTER’ after
entering the selection.
8. The selected meter factor and accompanying flow
rate will be displayed. Press ’ENTER’ to confirm
this selection or ’CLEAR’ to re-select.

10. Press ’START’ to begin flow. The flow rate
associated with the selected meter factor will be
used as the high flow rate. The batch will be
delivered. The flow rate ramp-down from first trip
to the end of the batch will be the same as if not
proving. Press ’ENTER’.
1200.00 Gal 1200.00
If, after the batch is completed, you press ’PRINT’, the
display reverts to the Ready Mode display and will not
go through the Auto Prove Sequence.
11. When the batch has completed, the AccuLoad
II will prompt for the actual prover volume.
Enter the prover volume and press ’ENTER’.

13. The AccuLoad II will then calculate the meter
factor. The new meter factor will be displayed.
Press ’ENTER’ to download this new meter
factor directly into the Program Mode. Press
’CLEAR’ for more options.
New MF 1.0101 Download?
(If the ’ENTER’ key is pressed, the AccuLoad II will
store the newly calculated meter factor as the
meter factor for that flow rate in Program Mode.)
Once it is stored, the display will read:
Meter #1 Ready 00:00:00
14. If the meter factor was not downloaded, the
operator may select that the newly calculated
meter factor be included in a running average
of meter factors.
(Note: A maximum of six proves may
be included in the meter factor average.)
Press
’ENTER’ to include this new meter factor in the
running average. Press ’CLEAR’ to ignore this
meter factor and proceed with the next prove.

15. The AccuLoad II will then average all meter
factors in the buffer (up to six of them). The
average meter factor will be displayed. Press
’ENTER’ to download the average meter factor
into the Program Mode. Press ’CLEAR’ to
proceed with the next prove. If a power failure
occurs while proving, any meter factors saved in
the average buffer will be lost.
Avg MF 1.0130 Download?
(If the ’ENTER’ key is pressed, the AccuLoad II will
store the average meter factor as the meter factor
for that flow rate in Program Mode.)
16. If a meter factor was downloaded, the AccuLoad
II will go return to the ready mode. Otherwise,
the AccuLoad II will go back to step 6 to continue
proving at this flow rate. Note that if the
AccuLoad II is in remote control mode,
authorization is required for each batch.
17. Each time a transaction is ended and a new
transaction is begun, the AccuLoad II will start a
new prove with step 1.
18. In the event that the meter factor is not
successfully downloaded, (Weights and
Measures contact open, factor out of range), the
following display will appear:
Mfac 1.0101 REJECTED
Local Ticket Printer
The description for operation with a local ticket printer
described below assumes: code 301 in the Systems
Directory is programmed for Local Tray Switch, the
additive injectors are selected for automatic (code
803) and that the permissive senses are met.
Before operation the display will read:
Position1 Ready 9:20:33
where Position1 Ready is the Ready Mode message
which is programmable in code 184 of the Systems
Directory. When the operator presses ’SET’ the
display will either prompt:
* PLEASE INSERT TICKET *
Note: This prompt is programmable in the 800 Systems Directory.
If the ticket has been inserted before the ’SET’ button
is being pressed, AccuLoad II will display:
Select Recipe
The driver or operator is required to enter a recipe
number (1 through 24) and press ‘ENTER’. The
display will indicate the recipe name and number that
has been selected.
Midgrade Recipe No 01
If the recipe that is displayed is correct press ‘ENTER’.
If the recipe that is displayed is not correct press
"CLEAR" and the AccuLoad II will return to the ’Select
Recipe’ display. If the recipe is correct and ‘ENTER’
has been pressed the AccuLoad II will display:
Midgrade P Gal
A predetermined volume to be loaded is entered at the
keypad. AccuLoad II will check this volume against the
maximum preset volume (program code 302 in the
Systems Directory) and the minimum preset volume
(program code 303 in the Systems Directory) when the
operator presses ’START’. If the volume is more than
the minimum preset volume and less than the
maximum preset volume, AccuLoad II will signal the
valve to open to start the product flowing. If the
volume is less than the minimum preset volume
allowable, the message
Preset Batch Volume is below the
Minimum required. Press
CLEAR TO CONTINUE
will scroll across the display until the ’CLEAR’ button is
pressed. If the volume is more than the maximum
preset volume allowable, the message

Section 2 - Operations
MN06053 Rev. 0.4 5/96 11
Preset Batch Volume exceeds the
Maximum Permitted. Press
CLEAR TO CONTINUE
will scroll across the display until the ’CLEAR’ button is
pressed. Press ’CLEAR’ again to clear the volume
entered from the display. Another entry can then be
made using a volume that is between the minimum
and maximum allowable preset volume as
programmed.
If the permissive senses are programmed and met and
an allowable preset volume is entered AccuLoad II's
(when the operator presses ’START’) valve will be
signaled to open to begin loading the product. The
volume entered is now locked into that preset position
and all of the loading controls, except ’STOP’ and the
Dynamic Displays, are inhibited.
At this time, the left and right-hand sides of the display
become counters. The first through the sixth positions
become an upcounter (delivery counter). The seventh
position becomes a space. The eighth through tenth
position displays the units of measurement. The
eleventh position becomes a space. The twelfth
through the seventeenth position continuously display
the original preset volume. The eighteenth position
becomes a space. The nineteenth through the twenty-
fourth positions become a downcounter (preset
counter).
11000 Gal P99999 88000
If AccuLoad II is programmed for a blank downcounter
(code 306 in the Systems Directory), the last five
positions will be blanked during the loading of the
product.
11000 Gal P99999
AccuLoad II can be programmed (code 345 in the
Systems Directory) so that the preset display, delivery
display, or both will alternate at a two second rate with
the current correction being applied to the delivered
volume (i.e., Grs, Raw, Gst @ Ref. Temp, Net @ Ref.
Temp, or Mass). For example:
11000 Gal P99999
will alternate with:
11000 Gal<Gst 60F 88000
if the current correction being applied to the delivery is
Gross at Standard Temperature and the programmed
reference temperature is 60 degrees Fahrenheit.
When the product being loaded reaches a
predetermined (First Stage Trip code 207 in the
Product Directory) value, the valve is signaled to
close. If a Smith Model 210 or 215 valve is being used,
the flow will ramp-down in multiple steps to assist the
valve in preventing line shock. When the preset
quantity is nearly reached, a final trip (code 208 in the
Product Directory) occurs signaling the valve to close
completely. If so programmed, AccuLoad II will
automatically adjust the final stage trip point (code 209
in the Product Directory) to assure accurate delivery of
the preset quantity for each load. The AccuLoad II will
also control the opening and closing of the standard
two-stage closure valves such as the Smith Model 296
or 299.
When the batch has been completed the AccuLoad II
display will alternate between:
1000 Gal P 1000 0
And
Preset completed
until the transaction is terminated by removing the
ticket or another batch is preset.
During normal loading, if the need arises to stop flow,
the red ’STOP’ key can be pressed to close the valve.
At this point the current batch delivery may be
terminated by pressing the ’SET’ button. The preset
display will appear and a new preset batch can be
entered or the transaction may be terminated. To
return the system to normal loading (i.e., return to the
volume remaining to be delivered), press ’Start’. If the
"Start After Stop Delay" is programmed (code 206 in
the Systems Directory) the display will read:
899 Restart in 10

Section 2 - Operations
12 MN06053 Rev. 0.4 5/96
(i.e., code 206 is programmed for 10 seconds) when
the 10 seconds have elapsed the display will alternate
between the preset display:
899 Gal P 1000 101
And
Press Start to Continue
until the ’START’ button is pressed to resume the
load. This reopens the valve to load the remainder of
the preset volume.
Caution: The ’STOP’ button is for operator
convenience only and is not intended to be used
as an "Emergency Stop" or as substitute for an
emergency stop device.
If a power failure is experienced, any transaction in
process will not be allowed to continue. The valve will
close and remain closed until after power is restored.
The display will go through the initialization process
and then read:
Press Start to Continue
The operator then can restart the load to complete the
batch by pressing ’START’.
Before Power Failure:
100 Gal P 1000 900
As Power Fails (left display):
*** Low Line Voltage ***
As Power Fails (right display):
** PLEASE STANDBY **
After Power Returns:
Press Start to Continue
After ‘START’ is pressed the batch will continue from
the point of the power failure.
The operator can print a ticket for either a single or a
multiple batch transaction. The upcounter display will
accumulate the total delivery until the transaction is
terminated by printing the ticket, up to six preset
batches, five digits up to 99,999 volume units.
Remote Ticket Printer
When operating with a remote ticket printer or a
shared printer the following occurs:
1. The AccuLoad II switches from:
Position1 Ready 8:07:15
to
Select Recipe
when the ’SET’ button is pressed. The operator would
then follow the same steps that have been described
in the description for the Local Ticket Printer.
2. At the end of the batch the AccuLoad II display will
alternate between:
1000 Gal P 1000 0
AND
Preset completed
until the transaction is terminated by the operator
by pressing the ’PRINT’ button. When the ’PRINT’
button is pressed the display will return to:
Position1 Ready 8:15:15
All other operations for the Remote Printer or the
Shared Printer are the same as described for
operation with the Local Printer.
