Introduction
TLS-50 Description
The TLS-50 Tank Monitoring System monitors up to six in-tank probes for a wide variety of fluids. Probes are
available to measure inventory only or inventory plus product temperature and/or water height. System status is
available to the operator through a front panel display and remotely, via an optional RS-232 serial interface port
(Figure 1).
Figure 1. Console Inputs And Outputs
SYSTEM OPTIONS
Two system options are available:
1. Alarm package - includes product level alarms and an overfill alarm activated relay output.
2. Alarm and Serial package - includes the Alarm package and an optional serial interface port providing three
user-selectable types of communication: printer, modem, or serial.

Introduction Restricting System Programming Access
2
-If Printer was selected in Communication Setup Type, the operator can print the Tank Status Report and
Inventory Report, and Setup Report and Diagnostic Report (if enabled). Note, the Diagnostic Report is only
for system troubleshooting and is not discussed in this manual. See the TLS-50 Site Prep Manual for a de-
scription of this report.
-If Modem was selected in Communication Setup Type, during the initialization sequence an auto-answer
command will be transmitted to the modem.
-If either Modem or Serial was selected in Communication Setup Type, the user may use a serial lan-
guage different from the local language (the serial language selections will be languages that map to the stan-
dard ASCII character set).
Restricting System Programming Access
To protect against unauthorized access to system operation, two security features can be enabled.
SYSTEM SECURITY
A switch in the console can be set to prevent access to the setup and diagnostic menus after initial programming.
SERIAL SECURITY
A switch in the console can be set that requires the operator to enter a 6-digit security code before the system will
respond to a serial command (models with Serial Package option only). The default serial security code is 000000.
The security code itself can be changed with a serial command. However, the serial security code switch must be
reset to the Open position to inhibit the security code requirement.

Front Panel Controls
The components on the front panel of the TLS-50 are shown in Figure 2. In addition to the front panel red LED
flashing when an alarm is activated, an audible beeper inside the console is also switched on.

Introduction Front Panel Controls

LCD DISPLAY
The front panel Liquid Crystal Display (LCD) contains two lines. When the system is in the Top Level Menu, the top
line of the display contains system status and/or alarm information. The bottom line contains Tank inventory
information. When the system is in one of the three Setup submenus, the top line displays the name of the Setup
menu and the bottom line displays the current setup parameter.
KEYPAD
The front panel keys are used to scroll through the tank parameter displays and to make changes to the system
setup.
Select key - press to scroll from one display to the next in the current menu. If the display
shown is the last in a submenu, the Select key scrolls the display up to the display at the
top of the submenu.
Enter key - press to scroll to the first display in the submenu of the current item. If the
current item does not have a submenu there is no response.
Back key - press to scroll back to the previous display in the current menu. If the
display is the first in a submenu, you scroll to the display that was used to enter
the submenu.
Silent key - press to deactivate the audible alarm annunciators; the internal
beeper and in the case of an overfill alarm, the remote overfill alarm output. If
another alarm occurs after the annunciators have been deactivated, the annun-
ciators will reactivate. The beeper and remote alarm output can be tested by an
extended key press of the Silent key.
Tank key - press to scroll to the next tank number.
Print key - press to print the report associated with the current displayed menu
item. If the report includes tank information, the report will contain data for all
configured tanks. This key is blank if the console does not have the Serial Pack-
age option.

Introduction Display Messages

Display Messages
TANK PARAMETERS
The following tank parameters are displayed one at a time as the operator scrolls through the Top Level Menu.
• Product Volume,
• Product Height,
• Temperature Compensated Volume - (requires probes that have temperature measurement capability),
• Product Temperature (requires probes that have temperature measurement capability),
• Water Height (requires probes that have water measurement capability).
Pressing the Tank key allows the user to select which tank's data is displayed. If a parameter is not available for
any tank in the system, that display will not appear as you scroll through the menus. When viewing a display that is
available in one of the tanks, but is not available for the current tank, a “NO DATA” message will be displayed for
that parameter.
ALARMS
When an alarm occurs, the console’s internal beeper will activate, the front panel LED will flash red, and the top
line of the display will contain the alarm message. In the case of multiple alarms, the main display screen will
automatically scroll through the active alarms. Press the Silent key to switch off the internal beeper. The red LED
will continue to flash until the alarm condition is remedied.
When an alarm condition returns to the normal state the alarm will be removed from the list of alarms. If no alarms
are active, the LED will return to the Normal state (continuous green), the beeper will be switched off, and the top
line of the display status line will read ALL FUNCTIONS NORMAL.
Table 1. Alarm Index, Cause, and Corrective Action
Alarm Cause Action
PROBE OUT Hardware failure - probe inoperative,
or its interconnecting wiring to con-
sole is damaged.
Call for service following the procedures estab-
lished for your site.
INVALID HEIGHT Product level too low, causing the fuel
and water floats to be too close
together.
Call for delivery.
LOW TEMPERATURE* Probe temperature drops below -4°F
(-19.8°C).
Probe returns to normal operation after probe
temperature rises above -4°F
(-19.8°C).
NO TANKS CONFIGURED No tanks are configured in Tank
Setup.
Configure at least one tank in Tank Setup.
MAX PRODUCT
(Alarm Package Option)
Product volume increased beyond
preset limit.
Stop delivery. Do not allow additional delivery until
product volume decreases below preset limit.
OVERFILL
(Alarm Package Option)

preset limit.
Call for delivery.
HIGH WATER
(Alarm Package Option)
Water level rose above preset limit. Remove water from tank.
*Note, an active LOW TEMPERATURE alarm will inhibit any of the Alarm Package alarms

Printing Out Reports
With the TLS-50 Console Serial Package option you can print the reports described in this section on any printer
that has a 9-pin dot matrix print head, a serial interface, and is capable of emulating Epson print commands. The
report formats will fit on either letter size or A4 size paper.
You press the Print key to print a report. However, what report you print depends on what is visible in the LCD
display.
PRINTED REPORT FORMATS
The TLS-50 Console must have the Serial Package option and have the following Communications Setup
selections enabled:
• Baud rate set to 9600 (recommended) - However, if you experience problems printing at 9600 baud, lower the
baud rate to 2400),
• Parity set to None (recommended),
• Data length set to 8 (required),
• Stop bit set to 1 (recommended), and
• Handshake set to XON/XOFF (may be required at the higher baud rates).
Note, for printing to occur, the TLS-50 and printer communications settings must match.
Inventory Report Example
TANK VOLUME TC VOLUME HEIGHT WATER TEMP

2 8813 - 79.1 3.2 -
3 11983 - 90.4 - -
Notes:
3. If the system setup parameter PRINT TC VOL is set to No, the TC VOLUME and TEMP columns will not print.
4. If none of the connected probes have temperature measurement capability, the TC VOLUME and TEMP
columns will not print. However, if any probes in the system have temperature measurement capability, the TC
Volume and TEMP columns will print for those probes, but not for the others.
5. If none of the connected probes have water measurement capability, the WATER column will not print.
However, if any probes in the system have water measurement capability, the WATER column will print for
those probes, but not for the others.
