Introduction Tank Gauge Transmitter
1.3 Operation
The ATT uses an incremental counting technique for determining liquid level. An initial level is identified as part of the
calibration procedure. Changes to that level are determined through incremental increases or decreases detected by
the ATT.
The host computer collects measurement information by polling the Advanced Technology Transmitter over a variety
of communication interfaces such as EIA485 and Mark/Space. Several communication protocols are supported. Among
them are Modbus and Mark/Space.
1.4 Configuration
The Varec Model 1200 Handheld Terminal is used to configure the ATT. It connects to the same ATTI bus used to
interconnect other input/output devices to the ATT. There is a special connection located inside the junction box for
the Handheld Terminal.
1.5 Construction
The Advanced Technology Transmitter is housed within an aluminum enclosure. The enclosure and assembly meet
explosion proof requirements and are environmentally sealed to prevent internal exposure to contamination.

differential communications network which allows up to 32 devices to operate on one network. The ATT and Modbus
master share a twisted pair of wires to communicate. Figure 2-4 illustrates the typical EIA485 wiring.
The communication distance that EIA485 can reliably travel is dependent on baud rate (communication speed), wire
quality, environmental noise, wiring configuration, and the number of multi-dropped ATTs. The recommended wire
for EIA485 systems is 18-gauge or larger, shielded, twisted pairs. The shield should be earth grounded at the Modbus
master (control system or computer end). The shield at the ATT should be open. The ATT B- power line acts as a
common reference tie to the Modbus master. Figure 2-5 on page 8 illustrates the EIA485 Modbus system.

2.5 Connecting the RTD
The following list shows how the ATT is wired to an RTD device. The ATT’s temperature circuit is designed to work
with a platinum or copper 3-wire RTD.
2.5.1 Connecting the Handheld Terminal
Figure 2-3 on page 6 shows how the 1200 Hand Held Terminal is connected to the ATTI bus on the ATT. The Model
268 can also be used to configure the ATT.
Warning! The 1200 Hand Held Terminal on the ATT is not Intrinsically Safe. Care must be taken to only use in a non-hazardous
environment
Wire as follows:
• Connect the RTD's A terminal to the ATT's terminal 6, A.
• Connect the RTD's B terminal to the ATT's terminal 5, C.
• Connect the RTD's C terminal to the ATT's terminal 4, C.
2.5.2 Wiring Completion
Caution! Do not overtighten metal plugs used to seal wiring compartment ports. Overtightening may damage the housing.
Properly seal the 1/2-inch NPT conduit entry. Install cover and tighten to ensure that the O-ring seal is adequately
compressed. Proper sealing of all ports is necessary to prevent moisture or other contamination from entering the
wiring compartment.
2.5.3 Installation Checkout
After a thorough check that all connections are correctly made and that all covers and plugs are installed, turn on
power to the ATT. Proceed to Chapter 3, Configuration.
2.5.4 Installation Checklist
The steps required in the installation process are summarized in the following checklist. Since each step is detailed

4000 Configuration
3 Configuration
The Varec Model 4000 Advanced Technology Transmitter (ATT) must be configured for the specific tank, attached
sensors, and host interface. This section provides detailed information on ATT configuration.
The ATT can be configured with a 1200 Hand Held Terminal or from a host program such as Varec TankView.
3.1 Configuration Parameters
Configuration parameters associated with ATT operation are entered and modified using the Model 1200 and can be
divided into the following areas:
• General Configuration - includes units of measure, level calibration, temperature type selection, and alarm
setpoints.
• Host Configuration - includes the type of host interface used, baud rate selection, and emulation modes for other
level transmitters.
3.2 1200 Hand Held Terminal
The ATT can be used with a 1200 Hand Held Terminal, see Figure 3-3 on page 13. The Model 1200 provides a local
terminal interface to configure the ATT and encoder at tankside. It is connected to the ATTI bus. It can be physically
attached via two banana plugs located inside the terminal block housing.
The ATT uses the Model 1200 in a different mode of operation. Normally, the Model 1200 polls the ATTI BUS device,
recognizes it, and goes into an internal menu system that is specifically tailored to that ATTI Bus device. The ATT
however, uses the Model 1200 in what is called ASCII Terminal mode. In this mode, the Model 1200 sends keyboard
activity to the ATT and displays screen information from the ATT. The ATT can not be configured with the Rosemount
Model 275 Terminal.
Because of the way the ASCII Terminal mode works on the Model 1200, the ATT is unable to poll any ATTI BUS device
while communicating to it. The ATT goes from an operational mode to an off-line mode. The operational mode is
automatically switched to when the Model 1200 is removed from the ATTI BUS bus.
Warning! The 1200 Hand Held Terminal on the ATT is not Intrinsically Safe. Care must be taken to only use in a non-hazardous
environment.
Function keys F1 through F4, defined in Figure 3-1 on page 11, are used for basic scrolling of the ATT menus and
selection of configuration parameters.

Terminal Mode Configuration
When the Model 1200 is connected to the ATTI Bus and turned on, a blank screen will appear on the Model 1200 after
a self test sequence. Pressing any key will cause the following screen to appear on the Model 1200 display:
The version indicated is the software version of the ATT.
Enter a "D" (to select Display Mode entries) or an "A" (to select Alter Mode entries) and press F4 (Enter).
If the Display Mode is selected with a "D", current status and configuration data may be examined but cannot be
modified. This mode is useful for verifying ATT configuration. This mode cannot be used to actively monitor ATT
operation, as normal ATT operation is suspended when the Model 1200 is connected.
Figure 3-1: ATT Alter Mode Menu Tree
If the Alter Mode is selected with an "A", all applicable configuration parameters can be modified. Figure 3-2 on
page 12 illustrates the display mode menu tree and Figure 3-1 on page 12 illustrates the Alter Mode menu tree. The
menu tree groups related items under separate menus and sub-menus. The menu grouping is provided to permit the
field operator to configure and display items in a related and logical order. Once a menu is selected, the operator can
scroll through related items.

When a parameter is encountered which is to be changed, pressing the F3 key (Alter) will cause the display of the
current parameter in a form which permits its modification.
When a specific set of parameters is available, the F1 and F2 keys can be used to scroll through the valid selections.
When the desired selection is displayed, pressing the F4 key (Enter) will cause selection of the new parameter. When
the parameter consists of numeric or free format characters, the Model 1200 keyboard can be used to enter the
parameter. Note that parameter alteration is not final until the session is completed with the EXIT AND SAVE command
from the Main Menu.
To complete parameter alteration, scroll through the Main Menu until the following display is presented, then press
F4 (Enter) to exit and save the altered parameters.
If parameter alteration is to be aborted (new parameters not saved), scroll through the Main Menu until the following
display is presented and press F4 (Enter) to quit without saving alterations. The QUIT or EXIT AND SAVE commands
must be initiated before turning off or disconnecting the 1200 Hand Held Terminal.
