Introduction

Mounted in a pre-wired NEMA 12 industrial enclosure, the LLC-BA Batch Controller provides
accurate and repeatable batch control, stores up to nine different programmable batch quantities,
and is a rate, total or batch indicator.
The LLC-BA controls batch operation with relay contacts to initiate and stop the flow. Two
separate relay outputs allow the control of two solenoids with different flow rates providing a slow
stop/start of the flow. The LLC-BA activates the low flow solenoid on the START input and after
a programmed variable DELAY, the high flow solenoid is activated producing a combined high
flow rate. The high flow solenoid is deactivated before the batch amount has been reached by
means of the PRECUT variable reducing the flow for a slow stop. The low flow solenoid is de­activated when the programmed batch amount is reached.
The LLC-BA compensates for a valve or fluid delay in the batch system with the Automatic Over-
run Compensation feature. The A.O.C. feature detects any overrun and the LLC-BA anticipates
and corrects for the delay on the next batch. This feature is always active and adapting
continuously to correct for long-term changes in valves and fluid characteristics.

Using a ΑSinking≅ Sensor

The LLC-E-BA accepts an Αactive≅ or Αsourcing≅ sensor output as standard. For sensors providing
an Αopen collector≅ or Αsinking≅ output, a pull-up resistor is required for operation as shown in the
LLC Input Circuit Detail below. The value of the pull-up resistor is selected so as to not exceed the
current rating of the pick-up output. Typical pull-up values range from 2.2KΩ to 5.1KΩ. The LLC-E­BA enclosure must be opened to install the pull-up resistor. The resistor is installed on the rear of the
LLC display module to terminals 1 and 3 on the upper connector. See Resistor Connection Detail
below for pull-up resistor installation.

Initial Display Messages

The LLC displays some initial messages at power up. After 5 seconds the LLC will briefly display
***AW Company*** and then the following four variables for approximately 2 seconds each. After
these brief displays, the LLC will display RATE or the last selected Mode.

VERSION a w 1 . XX - Indicates the software version installed in the LLC.

ON COUNT -> 00000XX - ΑON≅ count indicator increments each power-on cycle of the LLC.

LEFT MEM%0000100 - Memory life indicator displays % of memory life remaining in 10%

increments. The LLC stores programmed variables and retained totalizer values in EEPROM
(electrically erasable memory), not a battery. Limits to the number of times memory can be re-written
results in a minimum EEPROM life of 5 years with continuous use. This socket mounted memory IC
is field replaceable and replacement memory ICs are available. Care must be used to insert the new
memory IC in the exact same orientation as the one removed. Program variables require
reprogramming after memory IC change.

BLK LOC 0000XXX - Block Location, Used by LLC for EEPROM memory management.

Display Mode Selection

Display modes are selected differently in the PROGRAM Mode than in the RUN Mode.

While in the PROGRAM Mode, pressing the [MODE]-key (UP) changes the display mode from one
to the next. The [MODE]-key (UP) also selects which Totalizer may be reset while in the
Programming Mode.

When in RUN Mode, the Display Mode is selected by use of the momentary MODE toggle switch on
the front of the enclosure in the upper left hand corner. The modes are indicated on the LLC-E-BA
front label directly under the MODE switch in the order that they will appear. Pushing the MODE
switch down and releasing it quickly will change the display from one mode to the next. Holding the
MODE switch down causes the display to slowly scroll through the modes. The currently displayed
mode is selected as the switch is released. The Display Modes are: RATE (display rate), T01 (display
batch Total 1 as accumulating), T02 (display Totalizer 2), BATCH (display batch status), and T01­(display batch Total 1 as depleting). The display mode can also be changed by pressing the [MODE]-

UP).The LLC will retain the last selected display mode.

Display Modes

RATE Display Mode - In the RATE display mode the unit will display the rate in engineering units
based on the KFR factor with the decimal point at the selected location and the programmed
engineering units at the end. The word RATE appears at the beginning of the display to indicate the
selected display mode.

A typical display would be: RATE 00000.34 GPM

TO1 Display Mode - In TOTALIZER 1 display mode the LLC displays the total of the currently
programmed BATCH in progress. Totalizer 1 is reset to zero on a START input when in RUN mode
and will count up to the programmed batch amount. This total is retained by the LLC with the power
removed. The display is based on the programmed KFT value, KFT engineering units, and decimal
point.

A typical display would be: TO1 000010.0 GAL

TO2 Display Mode - In TOTALIZER 2 display mode the LLC displays the current total
accumulating in Totalizer 2 (Grand Totalizer). Totalizer 2 accounts for all totalized flow and can only
be reset in the PROGRAM mode. This total is retained by the LLC with the power removed. The
display is based on the programmed KFT value, KFT engineering units and decimal point.

A typical display would be: TO2 000496.8 GAL

BATCH Status Display Mode - The BATCH status display mode indicates the state of the currently
selected batch. This display indicates which batch is selected and whether the batch is RUNNING,
PAUSED, or DONE. It does not indicate actual batch progress.

A typical display would be: BATCH 1 DONE

TO1- Display Mode (INVERSE TOTAL 1) - Displays batch quantity in currently selected batch
when START input is closed and counts downward to zero at batch completion in the inverse function
of Totalizer 1. Display is reset with Totalizer 1. This total is retained by the LLC with the power
removed. The display is based on the programmed KFT value, KFT engineering units, and decimal
point.

A typical display would be: TO1- 00000.00 GAL

Operation/Reset of Totalizers

The LLC-BA has two independent totalizers, Totalizer 1 & Totalizer 2. TO1 is dedicated as the batch
totalizer. TO2 (Grand Totalizer) keeps a running total of all flow. TO1 & TO2 will rollover at
9999900 regardless of where the decimal is located. Totals are retained by the LLC with the power
removed.
NOTE: If power is removed during totalizing operation, the retained totals may not reflect the actual
total at the instant the power was removed since the variables retained at power down are updated
once every 15 seconds.

Totalizer 1 - Totalizer 1 is dedicated to the batch function and keeps the total of the currently running
batch. In the RUN Mode reset occurs at the start of each batch when the BATCH START/STOP
momentary switch or [BATCH]-key (SEL) are pressed. TO1 is also reset to zero by the RESET
BATCH momentary switch.
Totalizer 1 can be reset in the PROGRAM Mode by selecting the TO1 display mode using the
[MODE]-key (
briefly display RESET TOTAL 1 . TO1 display will be reset to zero by this operation and the TO1­display (inverse TO1) is reset to the quantity of the selected/activated batch.

Totalizer 2

LLC is in the PROGRAM mode and TO2 display mode. TO2 is not reset by any other function.
To reset TO2, select PROGRAM mode by turning the key switch to the vertical PROG position, select
the TO2 display mode using the [MODE]-key (UP), and press the [RESET]-key (DN). Totalizer 2 will
be reset by this operation and will start accumulating from zero. Use caution whenever in the
PROGRAM mode to prevent accidental reset of the totalizer! Total 1 and Total 2 are retained by the
LLC with the power removed.

Operating Modes

The LLC-E-BA has two operating modes, PROGRAM Mode and RUN Mode. The PROGRAM Mode
is used for programming variables and batch quantities or for reset of Totalizer 2. The RUN Mode
enables batch operation and the associated switches, inputs and outputs. The RUN/PROG key switch
selects the operating mode.

RUN Mode

To enter the RUN Mode place the key switch in the horizontal RUN position. The front panel
switches are now active for batch operation. Two touch-keys are also active on the front of the
display. The [MODE]-key (

Batch Operation - Once the start input is activated, the LLC-BA Batch Unit will activate outputs to
initiate flow and then deactivate the outputs when the selected batch quantity has been reached. One
of nine programmable batches can be selected using the Batch Select input. The RELAY outputs
control two solenoids with different flow rates to allow for a slow stop/start of the flow. In a typical
batch cycle:

RELAY1 Output (low flow solenoid) is activated by the START/STOP switch, remote

start/stop input or the [BATCH]-key (SEL).

After a programmed variable DELAY time, RELAY2 Output (high flow solenoid) is

activated producing a combined high flow rate.

RELAY2 Output (high flow solenoid) is deactivated before the batch quantity has been

reached by means of the PRECUT variable reducing the flow for a slow stop.

RELAY1 (the low flow solenoid) is de-activated when the programmed batch quantity is reached.

Automatic Over-run Compensation - The de-activation of RELAY1 is under the influence of the
Automatic Over-run Compensation feature that compensates for a valve or fluid delay in the batch

system. For example, if a valve with a .5 second reaction delay is used on a 1000cc. batch, the first
quantity delivered will be approx. 1020cc. depending on flow rate.
The A.O.C. feature detects this over-run and the LLC-BA anticipates and corrects for the delay on the
next batch. This feature is always active and adapting continuously to correct for long term changes
in valve and fluid characteristics.

Batch Stop/Start - Batch START/STOP is accomplished by momentarily depressing and releasing
the START/STOP toggle switch or momentarily closing and opening the Remote Start/Stop Input
(terminals 3&4). Batch START occurs on the rising edge of the signal as the START/STOP switch is
released or as the Remote Start/Stop Input is opened. If the START/STOP switch is depressed or the
Remote Start/Stop Input is closed again before the batch total has been reached, STOP will occur on
the falling edge of the signal as the START/STOP switch is depressed or the Remote Start/Stop Input
is closed. The Batch Status display will indicate PAUSED. Batch function will resume on the rising
edge of the next momentary closure of the STOP/ START switch or Remote Start/Stop Input. The

[BATCH]-key (SEL) also functions as the STOP/START switch in the RUN mode.

Batch Selection/Activation - Active in the RUN mode, the SELECT BATCH switch is used to select

and activate a programmed batch number (Batches 1- 9). Depress and hold the SELECT BATCH
switch to select a batch number. The display will read SEL B# 000xx.xx to indicate currently selected
batch number and batch quantity. Releasing the switch activates the Batch selection and returns the
display to the selected Display Mode. Each time that the switch is depressed, the batch number is
incremented by one. Repeat until the desired batch is displayed. Batch numbers with a zero quantity
cannot be selected/activated. The BATCH SELECT will advance to the next batch with a non-zero
quantity. Batches can be selected/activated in the PROGRAM mode using the [BATCH]-key (

SEL) to

select and the (ENT)-key to activate. See Programming Mode for details.

Batch Reset

- Active in the RUN mode, the momentary RESET BATCH switch is used to reset
batches. The batch totalizing value T01 is reset to zero as the switch is depressed. If a batch is in
progress, batch operation is terminated and T01 is reset to zero.

mA=s (+/-) Output - Active in the RUN mode, this analog output is batch progress signal or with
software revision 1.18 or higher can alternately indicate the currently selected batch number. The mA
output is available on terminals 1&2. See the O-set mA=s variable description for more information.
Batch Progress Signal – Signal directly corresponds with the progress of the batch where 4 mA
equals zero progress and 20mA is equal to the full batch amount.
Batch Number Signal – Value of mA indicates batch number in one mA increments with 5 – 13
representing batch numbers 1-9. To assign the output to the Batch Number Signal function it is
necessary to wire a jumper to the back of the LLC-BA controller between lower connector terminal 11
and terminal 13.

Entering/Editing the Variables

The LLC-BA must be in the program mode to enter the variables. To enter the Programming Mode,
turn the RUN/PROG key switch to the vertical PROG position. To enter or edit the variables, press
and hold the [PROG]-key (ENT). The display will start flashing PROGRAMMING ????. When the
display stops flashing, release the [PROG]-key (
DELAY, and is ready for the user to enter, edit or examine the variables. After each variable is
viewed/edited and the displayed value is stored, the LLC advances to the next variable.

DELAY

- This variable sets the delay time for Relay2 (high flow solenoid output) relative to the
START input. Typical delays are from 0.00 to 4.00 seconds. This function is used in slow start
applications where Relay1 (low flow solenoid output) is energized immediately at a START input and
Relay2 (high flow solenoid output) is turned on after the DELAY time.

Factory default is 00000.50 seconds

Press and hold the (UP) or (DN)-key to increment or decrement the variable value. To increase
the increment or decrement rate, while holding the (UP) or (DN)-key, press and hold the (SEL)-key
for medium rate or the (ENT)-key for maximum rate. When the desired value is displayed,
press the (ENT)-key to store the programmed value and advance to the next variable.
NOTE: Always release (SEL) or (ENT)-key before releasing the (UP) or (DN)-key or the LLC will
proceed to next variable leaving the last variable with an unpredictable value.

PRECUT - This variable sets the batch quantity remaining when Relay2 (high flow solenoid output)
is turned off. This variable is programmed using the KFT engineering units and decimal point. This
function is used in slow stop applications where Relay2 (high flow solenoid output) is turned off a
PRECUT amount before the total batch quantity is reached and Relay1 (low flow solenoid output)
remains energized until the batch quantity is reached.

Factory default is 0000000 pulses

Press and hold the (UP) or (DN)-key to increment or decrement the variable value. To increase
the increment or decrement rate, while holding the (UP) or (DN)-key, press and hold the (SEL)-key
for medium rate or the (ENT)-key for maximum rate. When the desired value is displayed,
press the (ENT)-key to store the programmed value and advance to the next variable.
NOTE: Always release (SEL) or (ENT)-key before releasing the (UP) or (DN)-key or the LLC will
proceed to next variable leaving the last variable with an unpredictable value.

GateTIME - This variable sets the sampling time for display of the incoming frequency. This variable
is programmed in complete seconds and the allowable range is from 1 to 30 seconds. This variable
will only effect the update of the display and is useful in stabilizing the display when dealing with
variations in flow. In low rate situations (below 10Hz.) the LLC converts automatically to pulse
width measurement to increase the accuracy of the display. The display will not function if this
variable is set to zero!

Factory default is 0000001 seconds

Use the (UP) or (DN)-key to increment or decrement the variable value. Press the (ENT)-key to store
the programmed value and advance to the next variable.

0-set mA=s - This variable is used to set the lower range of the mA output and as a fine offset
adjustment for the output. The variable is programmed with two decimal places of accuracy. The
allowable range is 0.00mA. to 10.00mA.. This variable has been factory set to produce a measured

4.00mA. at the output but can be changed to suit the users application or for fine offset adjustment of
the output. This variable only adjusts the analog output and does not effect the display.

Factory default is 0000x.xx mA* *(typ. 3.9x to 4.0x)

Use the (UP) or (DN)-key to increment or decrement the variable value. Press the (ENT)-key to store
the programmed value and advance to the next variable.

KFR-factor - For the LLC to display in a desired engineering unit such as GPM, an appropriate
scaling factor must be programmed. This factor is the KFR factor. The KFR is calculated using the
K-factor of the transducer being monitored. The K-factor is the number of impulses per engineering
unit established by the transducer manufacturer or by a calibration test.

Factory default is 00100.00 (Displays Hertz w/ two decimal places)

To calculate the KFR factor use the following formula:

KFR= TIME BASE CONSTANT/K-FACTOR

Where:

- 100 is the time base constant for eng. units per second

- 6000 is the time base constant for eng. units per minute

- 360000 is the time base constant for eng. units per hour

- K-FACTOR is the average number of pulses per desired

eng. unit that the transducer produces.

Remove the insignificant decimals often produced with this calculation as they will result in
displays with a misleading level of precision far exceeding the accuracy of the meter. Use a
maximum of four digits regardless of decimal point position! Enter KFR without regard to the
location of the decimal point in the display. The desired decimal location is entered in the next
procedure. The largest acceptable number for KFR is 65535.

A flowmeter has a K-factor 2053.7 imp/Gal and the display should read in Gal/Min.

KFR = 6000 / 2053.57 = 2.921741 for GPM

292174 is > 65535! 29217 > 4 digits! 2922 is best! Enter 2922 for KFR. For this

example, KFR=2.922, the decimal point is set to three decimal places in the next procedure.

Press and hold the (UP) or (DN)-key to increment or decrement the variable value. To increase
the increment or decrement rate, while holding the (UP) or (DN)-key, press and hold the (SEL)-
key for medium rate or the (ENT)-key for maximum rate. When the desired value is displayed,
press the (ENT)-key to store the programmed value and advance to the next variable.

NOTE: Always release (SEL) or (ENT)-key before releasing the (UP) or (DN)-key or the LLC
will proceed to next variable leaving the last variable with an unpredictable value.

DP for KFR - This variable selects the location of the decimal point in the KFR factor and the
display. This display will always be zeros with a decimal point.

Factory default is 00000.00

Use the (UP) or (DN)-key to move the decimal point left or right. Press the (ENT)-key to store the
location and advance to the next variable.

Eng=g UNITS KFR - The desired engineering units for display of rate are entered using up to three
programmable characters or letters. Example: gpm

Factory default is hz_

The first (left-most) character is programmed/edited first. To choose a letter press the (UP) or (DN)-
key until the desired character or letter appears. Press the (SEL)-key to enter the 1st character. Repeat
the procedure for the 2nd character and enter with the (SEL)-key. Repeat for the 3rd character and
store the last entry with the (ENT)-key. The next variable will display.

KFT-factor - For the LLC to display in a desired engineering unit such as Gallons, an appropriate
scaling factor must be programmed. This factor is the KFT factor. The KFT is calculated using the
K-factor of the transducer being monitored. The K-factor is the number of impulses per engineering
unit established by the transducer manufacturer or by a calibration test.

Factory default is 0010000. (Displays total pulses w/ no decimals)

To calculate the KFT factor use the following formula:

KFT= 10000/K-FACTOR

Where:

- 10000 is a constant

- K-FACTOR is the average number of pulses per desired

eng. unit that the transducer produces.

Remove the insignificant decimals often produced with this calculation as they will result in displays
with a misleading level of precision far exceeding the accuracy of the meter. Use a maximum of four
digits regardless of decimal point position! Enter KFT without regard to the location of the decimal
point in the display. The desired decimal location is entered in the next procedure. The largest
acceptable number for KFT is 65535.

For example:

A flowmeter has a K-factor 2053.7 imp/Gal and the display should read in Gallons.

KFT = 10000 / 2053.57 = 4.869568 for Gallons

486957 is > 65535! 48696 > 4 digits! 4870 is best! Enter 4870 for KFT. For this

example, KFR=4.870, the decimal point is set to three decimal places in the next procedure.

Press and hold the (UP) or (DN)-key to increment or decrement the variable value. To increase
the increment or decrement rate, while holding the (UP) or (DN)-key, press and hold the (SEL)-
key for medium rate or the (ENT)-key for maximum rate. When the desired value is displayed,
press the (ENT)-key to store the programmed value and advance to the next variable.
NOTE: Always release (SEL) or (ENT)-key before releasing the (UP) or (DN)-key or the LLC
will proceed to next variable leaving the last variable with an unpredictable value.

DP for KFT - This variable selects the location of the decimal point in the KFT factor and the
display. This display will always be zeros with a decimal point.

Factory default is 0000000.

Use the (UP) or (DN)-key to move the decimal point left or right. Press the (ENT)-key to store the
location and advance to the next variable.

programmable characters or letters. Example: Gal

Factory default is pul (for pulses)

The first (left-most) character is programmed/edited first. To choose a letter press the (UP) or (DN)-
key until the desired character or letter appears. Press the (SEL)-key to enter the 1st character. Repeat
the procedure for the 2nd character and enter with the (SEL)-key. Repeat for the 3rd character and
store the last entry with the (ENT)-key. The LLC will exit to the Display Mode.

This ends the variable programming procedure. The LLC-BA will display the currently selected
mode.

Batch Programming

The LLC-BA must be in the PROGRAM mode to program batch quantities. Nine different batches (1-

9) can be programmed. Program variables must be entered before the batch programming. Batch
quantities are based on the programmed KFT value, KFT engineering units and decimal point.

NOTE: The maximum value that can be entered for a batch is 429496 regardless of decimal
place. Values greater than 429496 will not be accepted. The more decimal places in the KFT, the

smaller the batch that can be programmed. To program larger batches it may be necessary to reduce
the number of decimal places in the KFT.

Example:
KFT = 214.38 and desired batch is 6000.00. Ignoring decimal location the value of 600000 is greater
than 429496 and will not be accepted. The solution is to reduce the decimal places of the programmed
KFT. With KFT changed to 214.4, batch will be 6000.0. Ignoring decimal location the value of 60000
is now less than 429496 and will be accepted.

To program a batch quantity, press the [BATCH]-key (SEL). The display will momentarily read SET
BATCH-->1 and then display BATCH1-> 0000000. Pressing the (SEL)-key again will increment the
batch number. With a batch selected, press and hold the (UP) or (DN)-key to increment or decrement
the batch quantity. To increase the increment or decrement rate, while holding the (UP) or (DN)-key,
press and hold the (SEL)-key for medium rate or the (ENT)-key for maximum rate. NOTE: Always

release (SEL) or (ENT)-key before releasing the (UP) or (DN)-key or the LLC may return to the
Display Mode leaving the batch quantity with an unpredictable value. When the desired batch

quantity is displayed, press the (ENT)-key to store the programmed value. This will also activate the
selected batch number and the LLC unit will return to the Display Mode. To program another Batch
quantity, repeat the above procedure. The [BATCH]-key (SEL) and (ENT)-key can be used for batch
selection /activation when in the PROGRAM mode. When programming is completed, the
RUN/PROG key switch must be returned to the horizontal RUN position to enter the RUN mode and
execute any selected/activated batch.

This ends the batch programming procedure. The LLC-BA will display the currently selected mode.
To initiate batch operation, the RUN/ PROGRAM key switch must be set to the horizontal RUN
position to enter the RUN mode.
