Introduction
Overview
This manual describes the installation, setup, and operations for the DIS-51 unit
sold by Gilbarco Veeder-Root.
The DIS-51 displays ullage as determined by the TLS console up to the tank
capacity. Use the display for this purpose only.
Safety Precautions
The following safety symbols are used throughout this manual to alert you to
important safety hazards and precautions.
EXPLOSIVE
Fuels and their vapors are
extremely explosive if ignited.
FLAMMABLE
Fuels and their vapors are extremely
flammable.
ELECTRICITY
High voltage exists in, and is
supplied to, the device. A poten-
tial shock hazard exists.
TURN POWER OFF
Live power to a device creates a
potential shock hazard. Turn Off
power to the device and associated
accessories when servicing the unit.
WARNING indicates a
hazardous situation which,
if not avoided, could result
in death or serious injury.
NOTICE is used to address prac-
tices not related to physical injury.

Introduction General
Keep out of reach of children!
General
The DIS-51 unit allows a tanker driver to connect with the station’s ATG to view
continuous level measurements for up to 32 tanks, ullage for the tanks, as well as
any alarms and warnings.
The DIS-51 display is mounted to the inside window of the station. It is operated
by the tanker driver using a push-button switch mounted outside the station in view
of the display. Pressing the button activates the display. Pushing the button
repeatedly displays tank status for each tank. The display clears when the button
has not been pressed for a long period of time.
WARNING
The equipment is used in location where lethal voltages and
explosive vapors or flammable fuels may be present.
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS
AND SAFETY PRECAUTIONS COULD CAUSE DAMAGE TO
PROPERTY, ENVIRONMENT, RESULTING IN SERIOUS
INJURY OR DEATH.
For this system:
1. Installers and operators must comply with all
applicable safety regulations. This also applies to any
local safety any accident prevention regulations which
are not stated in this manual. In addition, take
necessary precautions during installation, service, and
repair to prevent personal injury, property loss and
equipment damage.
This device must be installed into an electrical system
complying with the plant engineering regulations in
force and equipped at least wih a 2-pole, 6A, C curve,
MCB differential for supply line.
2. The installation of the DIS-51 including wiring to the
TLS console may be only carried out by expert
personnel. Refer servicing to trained and qualified
personnel only.
3. Do not change or modify the display or all any
equipment without the prior consent of Veeder-Root.
4. Substitution of components may impair intrinsic safety.
5. Be sure AC power is “Off” before opening the TLS cover
to access communication jumpers. Do not short any
voltage across any barrier terminal.

Introduction Gauge Requirements
Gauge Requirements
The DIS-51 can be connected to a Veeder-Root TLS-2, TLS-350, TLS4 or TLS-
450/TLS-450PLUS tank monitoring console via a RS-485 serial communications
port.
Cable Installation
Cable must be installed to comply with all local and national regulations that may
be in force at the time of installation. It is the installer’s responsibility to ensure that
the installation complies with all relevant and pertinent legislation and codes of
practice. Figure 1 shows the wiring connections for DIS-51 system components.
Do not run DIS-51 cabling in the same ducts as intrinsi-
cally safe TLS probes or sensors.
Figure 1. System Block Diagram
Location
The DIS-51 display is designed to be mounted against the inside window of the
kiosk and visible to the tanker driver outside the window. After determining the
ideal location for mounding the display, ensure the window is clean and dry.

Introduction Connections
Remove the protective paper from the sticker on the front of the display (Figure 1),
press the display firmly against the inside of the window.
Enough space must be left underneath the unit to allow the power lead and the
RS-485 cable to be connected, approximately 70 mm.
In case of Automatic Mode installation, the push button can be removed but it is
important to complete the DIS-51 configuration before removing the button and
attaching the display to the glass of the window.
The DIS-51 and installation kit (including junction box
and push-button switch) are not intrinsically safe and
must not be located in areas what may contain explosive
or inflammable concentration of petroleum vapor.
Once installed avoid getting window cleaning agents, water, etc. onto the DIS-51
display.
Connections
The cable that comes with the DIS-51 is two meters long with 7 pole connections.
The signals on this wire are shown in the Table 1 below.
The wire connectors are used to connect the wires to the power supply, push-
button switch, and cable coming from the TLS console. These connections are
done inside the junction box (see Figure 2).
Wiring Connections
The junction box is equipped with a protection fuse. If necessary, only replace the
protection fuse with one having the same characteristics: 1A, glass 5x20mm T.

DIS-51 To TLS Console Wiring Connections
This section includes instructions for configuring the jumpers and serial ports and
setting up the software for applicable TLS Consoles. Instructions are specific to
each console type.

switch for more than10 seconds.
Once in the Configuration Main Menu, the following actions can be triggered by
pressing the push-button switch as discussed below:
Pressing the push-button switch for less than 2 seconds (short press):
• The cursor (<) moves to the next line item in the menu.
• If the cursor is on the bottom line of the display and another menu item exists,
that menu item will be displayed in the bottom line.
• If the cursor is on the last available menu item, it jumps back to the top item in
the menu.
Pressing the push-button switch for more than 2 seconds (long press):
• If the cursor IS on the top line item of a menu, it returns to the next higher menu
or leaves the Configuration Main Menu.
• If the cursor is NOT on the top line of a menu, the selected menu is opened, or
the configuration is selected/changed.
After exiting the Configuration Main Menu, all changes are automatically stored and
saved even after turning off the system.
