I. SYSTEM OVERVIEW
INTRODUCTION
The K SYSTEMS K1600 Tank Inventory system is a micro-processor based inventory
control system designed for high accuracy measurements of liquid contents of up to 16 storage
tanks. The inventory and alarm status of each tank can be viewed on a large 4x20 LCD display.
Tank inventory is continuously run in the background even while the operator has control of the
system through the LCD display and the front panel key pad.
The K1600 can be configured to accept up to 16 pneumatic or 4-20 milliamp input
signals from the sensors in the tank. This signal is converted from analog to digital (ATOD)
counts which, in conjunction with the entered specific gravity and programmed tank profile
tables, are utilized in determining the correct inventory value. The K1600 can manually or
automatically compensate for zero shift of input signals directly from the display without

4
having to adjust at the sensors.
Alarm setpoints, Product names and Specific gravities, Transmitter zero values and
Time/date can easily be changed by authorized personell through use of multi-level access
codes and the functionally labeled keypad on the front panel.
Inventory for individual or multiple tanks can be viewed on the display by pressing the
RUN/PAGE button. Once on the desired display page additional tanks can be viewed by pressing
the up/down arrow keys. In addition inventory can be read in POUNDS or GALLONS (LITERS or
KILOGRAMS) by selecting the UNITS button.
Optional field programmable alarm outputs, an RS232 communication port, and
Printout capability allow accurate inventory information to be brought out to a host of
peripheral devices for reporting and control.
Although the K1600 Tank Inventory System is micro-processor based, it is functionally
driven and requires little knowledge and understanding of computers. All functional displays
and operations can be accessed from either the single or multiple tank display screen by
selecting the button which corresponds to the desired operation.

MULTIPLE TANK DISPLAY
The K1600 Multi-tank display is a two page display where tanks are arranged in 2
columns per page as defined by channel numbers 1-4, 5-8, 9-12, 13-16. Page 1 shows the
inventory levels of channels 1 through 8 (tanks 1-8) and Page 2 displays channels 9 - 16
(tanks 9-16). Each tank has a status mark which becomes active when an alarm condition
exists (see TANK LEVEL STATUS below). While all tank inventories are continuously updated,
the operator can easily toggle from Page 1 to Page 2 by using the scroll keys. The <PAGE> key
can be used to toggle from the Multi-tank display to the Individual tank display where more
complete tank information can be viewed.

II. DESCRIPTIONS
CHANNEL NUMBER
During the initial set-up of the system each tank is linked in software to an input
channel number as defined by hardware on the analog input board (See System Set-up and
Installation). The channel number also defines the Multi-tank display location of a tank and is
used throughout the system to identify a particular tank's data shown on display screens where
actual tank names cannot be written. Channel numbers are displayed on the Multi-tank
displays prior to the particular information requested. On the Single tank dislpays the channel
number is usually preceded by the characters "CH" as in CH:12. There are 16 available
channels, one for each tank. The actual number of channels used and displayed is typically
determined by the number of tanks on the system. When in the appropriate mode, channel
number can be incremented or decremented using the scroll keys.
TANK NAMES
Tank names or designations which define a particular tank appear in the upper left-
hand corner of the single tank display and consist of up to six characters. Names such as RT 1,
PT 6, or TANK 3 help the operator identify a tank. Tank Names are supplied by the customer
and are entered into the system prior to shipment as part of the initial factory set-up. These
names are stored in E-prom memory and will not be lost during a power outage. Tank names
cannot be altered in the field through use of the keyboard entry system.
UNITS
The K1600 will readout in English or metric units as either Pounds and Gallons or
Liters and Kilograms. Units define the units of measure in which the inventory value is shown
and appears on the Single tank screen in the upper right-hand corner following the actual
inventory value displayed. On the Multi-tank screen units are indicated in the center of the
display on the 1st line. Pressing the <UNITS> button toggles the display and inventory values
between the units of measure programmed.

9
PRODUCT NAMES
Product names on the Single tank screen appear on the 3rd row , left-hand side of the
display. These names identify the product selected by the operator for the tank shown. Up to 18
product names consisting of a maximum of six characters are supplied by the customer and are
pre-programmed at the factory during initial set-up prior to shipment. Similar to Tank
Names, Product Names are stored in E-Prom memory and will not be lost during a power outage
nor can they be altered through the keyboard entry system. On the Multi-tank screen product
names can be viewed by pressing the <PROD> button on the front panel. The product names
will be preceded by the appropriate channel number.
(See Viewing Data - Multi-Tank)
SPECIFIC GRAVITY
Product specific gravity is indicated on the Single tank screen only on the 3rd row
directly to the right of the product name. Specific gravity refers to the weight of the product in
the tank which directly effects the head pressure being measured. The specific gravity of the
product displayed has a direct effect on the accuracy of the inventory value and as such care
should be taken to insure that the proper "SPGR" is shown. Even though the product name is
correct, incorrect SPGR can adversely effect the inventory value indicated. The correct
specific gravity for a product is entered and linked to the product name during operator
programming so thereafter, a product name selected from the Product list simultaneously
selects the correct specific gravity. (See User Programming- Product Name)
PERCENT FULL
Line 4 of the Single tank display indicates how full the tank is in percentage of volume.
GENERAL ALARM STATUS LINE
When an alarm is encountered during normal operation or in the programming mode,
line 1 or 4 of any display is replaced by the general alarm status line. This will alert the
operator of an alarm condition in a tank. The operator will be cued to silence the audible alarm
(optional) and acknowledge, <ACK>, the alarm. After acknowledgement is complete, normal
operation will resume. Multiple alarms will be processed on a first in - first out basis.

10
LEVEL ALARM STATUS
There are three level setpoints per tank (HI - MID - LO) which are programmed by the
user. When the level in the tank reaches a setpoint line 1 or 4 on the screen is relpaced by the
General Alarm Status Line . After all alarms have been acknowledged the display returns to its
normal appearance. However, the level status indicator is now activated for the alarms
acknowledged. Level alarm status indication appears on both the Single and the Multi-tank
screen in various forms. The Multi-tank screen displays an astericks ( *) for high level, the
letter "M" for mid level and the letter "L" for low level. These characters appear immediately
following the channel number. If there is no indication in the level status column for a
particular tank then the actual product level in the tank is between the lo level and the mid
level setpoint.
The letter "E" appearing in the level status column indicates that the product level is
at or below the level sensor in the tank.
The Single tank screen displays the tank level status on the 2nd line after the channel
number and preceding the word "LEVEL". When the tank product level is at or above the Hi-
level setpoint the characters "HI" appear. Similarly when the product level is at or above the
Mid-level setpoint and below the Hi-level setpoint the characters "Md" appear. The characters
"OK" are displayed when the product level is betweem the lo-level and the mid-level setpoints.
"LO" appears when the level is at or below the lo-level setpoint. When the product level is at
or below the tank sensor the characters "EMPTY" appear on the screen.
(CAUTION: Even though the screen reads "empty" product may remain in the
tank below the level sensor)
ANALOG TO DIGITAL COUNTS
The K1600 uses a 12-Bit Analog to Digital converter which normally converts a 4-
20 Ma current input signal to 0-4096 digital counts. The K1600 utilizes a "LIVE" zero and
condensed span adjustment so that a 4.00 milliamp input produces 50 AtoD counts and a 20
milliamp input produces 4050 counts. The system micro-processor then utilizes these digital
counts in determining the product level in the tank. The current ATOD count for each tank can
be viewed individually from the Single tank screen by pressing the <TIME/ZERO> button. These
values can be used as a reference to view and/or adjust the transmitter zero offset when a tank
is empty.

11
TRANSMITTER ZERO OFFSET - MANUAL/ AUTO ZERO FUNCTION
The K1600 is designed to accomodate tank transmitters with either a direct 4-20 ma
output or a pneumatic pressure output transduced with the KIO Pneumatic Interface to a 4-20
milliamp signal.
The K1600 utilizes a "live" zero to provide an easy means of adjusting the inventory
display for transmitter zero shift both above and below 4.00 ma. The transmitter Zero Offset
represents the Analog to Digital count conversion by the AtoD input card which corresponds to
the transmitter output when the product level in a tank falls below the transmitter. Typically
the zero setting for a transmitter equals 4.00 ma with a corresponding Zero Offset AtoD value of
approximately 50 counts. The Zero Offset value for a particular tank can be viewed by
pressing the <TIME/ZERO> button when in the Single-tank display mode and verified by
comparing it to the actual AtoD count currently being converted from the level sensor when the
tank is empty. Both ATOD values should be identical. If they are not, corrections can be
programmed directly to the zero offset at the K1600 without physically adjusting the tank
sensor. This is refered to as the Manual Zero Function.
Shifts in P/I transmitter zeros with pneumatic sensors, when used in conjunction with the
KIO-12 or KIO-16 pneumatic input enclosure, are automatically monitored and compensated for by the
K1600 on a preprogrammed time interval and therefore cannot be mannually programmed. This is refered
to as the Auto-Zero Function.

12
III. VIEWING DATA
The K1600 INVENTORY SYSTEM will display tank inventory and information in either a
Multi-tank or Single-tank mode. In the single tank mode much of the pertinent information for
a tank can be viewed all at once. Due to obvious space constraints the Multi-tank mode will
display much less information for each tank. However, when required all data can easily be
viewed by the touch of a button.
Parameters which can be viewed and changed from either display mode are:

IV. PROGRAMMING AND CHANGING DATA
Changing tank parameters can be performed from either the Single-tank or the
Multi-tank screen by activating the programming function when viewing the appropriate
parameter screen.
Programming is initiated by pressing the <PROG> key which activates the numerical
keypad on the front panel. A flashing curser appears on the screen and the system is now in the
programming mode awaiting input from the keypad. The program mode can be terminated by
either: A. Pressing the <PROG> button again which terminates programming at the point where
the programming function was entered and no changes to the entry are made
B. Pressing the <RUN/PAGE> button which terminates the programming mode, no
changes to the field are made and returns the system to the inventory screen last
viewed
C. Pressing the <ENTER> button which records the new entry in the data field and
either moves to the next programmable data field on the page or moves to the next
screen and terminates the programming mode.
ACCESS CODES
The system recognizes three codes that allow access to restricted programming areas.
These three unique codes are programmed through the system and correspond to three levels of
clearance: Low, High, and Master. The Master access code is reserved for areas in the system
which are used to initially set up the system parameters and is not normally accessable to plant
personell while High and Low access codes allow Operator entrance to select areas.
As previously stated all display pages may be viewed and all viewing functions can be
executed without any access code requirement. In these cases operation of the function begins
immediately upon selection of a particular function command.
However, programming requires that a valid access code be entered before execution of
the desired procedure can be permitted. When access codes are required the access code prompt
will be displayed. If a valid code with equal or higher clearance than that required by the
selected procedure is not entered at this point, the system will deny access to that procedure.

16
Access codes must be entered during the program phase, when prompted, in order to
modify tank or product parameters. Appropriate code levels required to change parameters
are listed below (a higher code level than required is acceptable).
