1 Introduction
1.1 Using This Manual
This manual is designed to assist the user with the installation, configuration, operation,
maintenance, and troubleshooting of the Varec Model 4000 Advanced Technology
Transmitter (ATT).
1.2 Getting Acquainted with the Advanced Technology Transmitter (ATT)
The Varec Model 4000 Advanced Technology Transmitter (ATT), in conjunction with a
host, represents a data acquisition and communications system for use in liquid level
measurement and/or other measurement applications. Liquid level measurement is
provided by the Advanced Technology Transmitter coupled to a Varec Model 2500 or
other level gauge, as shown in Figure 1-1.

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.

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.

2.1 Overview
This section contains instructions for unpacking, mounting, grounding, and wiring the
Varec Model 4000 Advanced Technology Transmitter (ATT) assembly. An installation
checklist is also included.
Warning! To avoid electric shock and possible injury, do not perform any service procedures
other than those specified in this manual. These installation instructions are for use
by qualified service technicians.

2.1.1 Unpacking
Remove the ATT from the shipping container and inspect it for evidence of shipping or
handling damage. Report any shipping damage to the carrier. Verify that the contents
of the shipping container agrees with the packing list.
2.1.2 Storage Prior to Installation
If the ATT is to be stored prior to installation, it should be repackaged in its shipping
container and stored in a temperature and humidity controlled environment.
2.1.3 Becoming Familiar with the ATT
The ATT is housed within an explosion proof enclosure. A cover is provided to permit
access to both the electronics and backup batteries.
3/4- and 2 1/2-inch NPT plugs are provided for wiring access. Wiring to the ATT
consists of connecting power, host communication, RTD input and an optional ground
connection.
2.1.4 Hardware Configuration
All configuration is performed using the Model 1200 Handheld Terminal or a download
from a host computer. However, certain parameters such as communication address and
speed must be configured via the Model 1200 Handheld Terminal.

2.2 Mounting the Equipment
The ATT is bolted to the Model 2500 Automatic Tank Gauge head as illustrated in
Figure 2-2. It may also be mounted to Endress+Hauser, Sakura, Tokyo-Keiso, Shand &
Jurs, and Gauging Systems, Inc. float and tape gauges with the Endress+Hauser adapter
shown in the following table.
Mounting the ATT to the Level Gauge is accomplished in the following manner:
1. Remove the back cover of the Level Gauge.
2. Remove the access cap from the back cover of the Level Gauge.
3. Mount the ATT in place of the access cap, making certain that the word "TOP" cast
into the housing lines up with the top of the Level Gauge back cover.
4. Install the Level Gauge back cover with the transmitter in the Level Gauge. Make
certain that the slot in the ATT drive coupling engages with the pin on the tape
sheave of the Level Gauge.
5. Proceed with field wiring.

2.3 Grounding the Equipment
Warning! The ATT must be grounded before communication and power connections are
made.
An external grounding lug is provided on the ATT. A connection from the ground lug to
earth ground must be made before any other wiring connections are made.
Note! For adequate/proper operation of the ATT lightning arrestor, a ground strap must be
attached to the ATT. Grounding through mounting kits or pipe coupling is not ade-
quate.
Note! Properly seal all ports to prevent moisture or other contamination from entering the
wiring compartment.
2.4 Wiring
Connections should be made in a conventional manner according to local or plant
electric codes.
Warning! Explosion-proofsealsmustbeinstalledinallwiring entries.Anyunusedentriesmust
be plugged with pipe plugs and secured with Loctite®, or equivalent.
2.4.1 ATT Wiring
Wiring the ATT is described in the following paragraphs. The wiring diagram provided
in Figure 2-3 on page 6 should be used in conjunction with these wiring instructions.
2.4.2 Wiring Preparation
Remove the two thread protectors from the 1/2-inch NPT conduit entries at the top and
bottom of the ATT. Remove the rear cover from the ATT housing.
2.4.3 Connecting Input Power
Warning! When connecting DC power leads to the ATT, make certain that power is OFF.
The ATT operates on a 24-48 volts DC power source. The input power connection to the
ATT is accomplished in the following manner.
Connect the positive side of the power supply to terminal 10, B+, and the negative side
to terminal 9, B-, of the terminal block assembly. See Figure 2-3 on page 6.

2.4.5 ATT EIA485 Wiring
The ATT uses a 2-wire EIA485 hardware interface to communicate with the Modbus
master. EIA485 is a high speed 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.

2.4.6 ATT Mark/Space Wiring
For an ATT using the Mark/Space field communications option, the following additional
wiring connections must be made. (Refer to Input Power Wiring in Section 6 to determine
the minimum wire size required.). See Figure 2-6.
• Run two twisted pairs of 18 AWG wire (Mark/Space wires) into the ATT through the
conduit entry along with the 48 VDC power wiring.
• Connect the Mark line to terminal 11, M/485-, and the Space line to terminal 12,
S/485+, on the terminal block assembly.

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. Overtighten-
ing 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
