1.1 OVERVIEW

This inductive conductivity transmitter has been

designed for easy installation and shipment. The pur-

pose of this section is to provide information on the elec-

trical configurations and the physical mountings

available. Prior to discarding the packing case:

If it is damaged, the transmitter may have also

sustained damage. Contact the carrier at once.

Remove all items shown on the packing list and

note any exceptions.

1-1

The Model 4081T conductivity transmitter is designed to

make accurate measurements while the sensor is sub-

mersed in the process stream. Measurements can also

be tailored to high temperature and/or high pressure

streams. The specific ranges covered are controlled by

both hardware and software.

1.2 MECHANICAL INSTALLATION

The Model 4081 T Transmitter is suitable for installation in

harsh environments.

• For best operation, locate in an area where tempera-

ture extremes, vibrations, electromagnetic, and radio

frequency interferences are minimized or absent.

The transmitter is equipped with two 3/4 in. FNPT conduit

openings, one on each side of the transmitter housing.

• Remove the terminal end cap.

• With the transmitter positioned with the wiring terminal

side of the enclosure opened (as seen in Figure 1-2),

use the left conduit opening to bring in the sensor

wiring, and the right side conduit opening for power

supply/current loop wiring.

• To prevent moisture from entering the transmitter

housing, use weathertight cable glands supplied by

others.

NOTE

Moisture accumulation in the transmitter

housing can affect transmitter performance

and may void its warranty.

• If conduit is used, connections on the transmitter hous-

ing should be plugged and sealed (with tape, pipe com-

pound, or sealant) to prevent moisture accumulation in

the terminal side of the housing.

• The transmitter must be installed so that the conduit

openings are not on the top, because moisture can

accumulate in that position.

• The transmitter should be easily accessed by operating

and maintenance personnel.

1.2.1 Flat Surface Mounting. The transmitter may be

mounted on a flat surface (see Figure 1-2) using the thread-

ed mounting holes on the bottom of the transmitter.

1.2.2 Pipe Mounting Bracket. An optional pipe mounting

bracket is available. See Figure 1-3 for mounting information.

1.3 ELECTRICAL INSTALLATION

1.3.1 Conductivity Sensors

Rosemount Analytical Inc.’s inductive conductivity sensors

with PT100 are compatible with the Model 4081T transmit-

ter. Please refer to Figures 1-4 thru 1-6 for appropriate

sensor to transmitter wiring. The sensor cable should be

routed through the conduit opening closest to the Pin 2

connection.

1.3.2 Power Supply/Current Loop Wiring.

The Model 4081T operates within a range of 9-32 VDC

power. The power supply wiring routes through the conduit

opening closest to pin number 16. Connect as illustrated in

Figure 1-7. For shielded power supply cable, the shield

should be connected to the earth ground connection.

The Model 4081T sensor connection requires connecting

the white toroid wire (see Figure 1-5) to either TB-1 pin 11

(indicated on the inside of the terminal end cap) for high

range, or TB-1 pin 12 for low range. To access the terminal

block, unscrew the terminal end cap.

1.3.3 Hazardous Area Installation

In order to maintain the hazardous area rating for installed

transmitter, the following drawings must be used:

Figure 1-9. Wiring for FM Explosion-Proof Installation for

Model 4081T (Drawing Number 1400175)

Figure 1-10. Wiring for CSA Intrinsic Safety for Model 4081T

(Drawing Number 1400190). See also label (right).

Figure 1-11. Wiring for FMRC Intrinsic Safety for Model

4081T (Drawing Number 1400185).

1.4 INSTALLATION VERIFICATION

1.4.1 Overview. Verification of installation includes ensur-

ing that the proper precautions have been observed during

the installation process and recognizing whether the

instrument is operating properly upon power up.

1.4.2 Precautionary Checklist. Before applying power

verify the following:

1. Sensor wiring and power supply/loop wiring are not in

the same conduit.

2. Sensor or power supply/loop wiring are at least 12

inches from any high current lines.

3. Sensor chosen is compatible with the 4081T

Transmitter.

4. Terminal end cap has been replaced.

1.4.3 Power Up. Activate power supply. Upon powering

up, with the sensor in solution, the transmitter:

1. Should display a live conductivity reading in large, dark

numerals on a gray background.

2. Should display the present temperature in smaller numer-

als on the lower line of the display screen.

3. Should NOT have the word FAULT or HOLD appearing on

the left edge of the display. The display should not be flash-

ing.

2.1 GENERAL

The Model 4081T transmitter operates in either the

Process or Program modes. The process mode screen

is illustrated in Figure 2-1 and the program mode screen

is illustrated in Figure 2-2.

2.2 DISPLAY

2.2.1 Process Mode (normal operating mode). When

operating in this mode:

• The primary process variable (the conductivity) is

continuously displayed (see 1 in Figure 2-1)

• Engineering units are determined by the process

display mode

• Temperature output is in °F or °C (see 2 in Figure 2-1)

2.2.2 Program Mode (programming or calibrating

mode — step-by-step instructions for programming

and calibrating the transmitter are given in Sections

4.0 and 5.0, respectively). When operating in this mode

the following information is provided on the instrument

display:

• Continuous display of the primary process variable

is still available.

• Menus are displayed below the process variable.

The active subset title is in bold print (see 1 in

Figure 2-2).

• Security ID (see Section 4.4, step 10) and prompts

are displayed below the segments (see 2 and 3 in

Figure 2-2).

• FAULT is displayed (see 4 in Figure 2-2) when a

transmitter disabling condition occurs. When in the

fault mode, the fault indicator lights up and the

process variable flashes. The program mode must

be entered to see the descriptive fault message.

• HOLD (see 5 in Figure 2-2) becomes visible when-

ever the transmitter is placed in the hold or test

function. Hold is most often used when

servicing/cleaning the sensor. It initiates the simu-

late mode.

2-2

2.3 INFRARED REMOTE CONTROL (IRC)

The IRC is the most convenient way to calibrate, pro-

gram, or access the diagnostics in the transmitter. It

operates the same as other remote controllers.

For best operation, the IRC should be within six feet of

the transmitter and aimed directly at the infrared sensor

window (small square window at top of display) at an

angle of no more than fifteen degrees. The amount of

ambient light may also affect IRC communication.

2.3.1. The overall menu structure is shown in Figure 2-4.

The top level functions available to the IRC (CAL,

PROG, and DIAG) are shown on the display with the

active menu segment highlighted as described in

Section 2.2.

2.3.2. Menu Keys. The three primary menu structures

are Calibrate (CAL), Program (PROG), and Diagnose

(DIAG). They are shown horizontally on the screen and

have separate keys on the IRC (see 1, 2, and 3 in Figure

2-3). Pressing the labeled key will provide access to that

menu.

2.3.3. Program Command Keys. The three program

command keys are labeled ENTER, NEXT, and EXIT

(see 4, 5, and 6 in Figure 2-3). These keys are used as

follows:

ENTER: This advances down through the sub-

menus to the prompts, will save the new value,

and activate NEXT.

NEXT: This advances the program to the next

sub-menu.

EXIT: This key is used to abort the current sub-

menu operation and return to the previous

menu segment.

2.3.4. Editing Keys. These keys are used to edit input

variables (see Figure 2-3). The left/right arrows change

the location of the prompt and causes the integer to

flash. These also allow access to the measurement unit

and decimal place location. When a flashing mnemonic

appears on the display, the UP and DOWN arrow keys

scroll up or down through the list. When numbers are

shown, the UP and DOWN keys change the value of

the digit.

RESET: Aborts the current operation and

returns to the process display screen (see 8 in

Figure 2-3).

HOLD: Accesses prompt to toggle between

enable and disabling of this function (see 9 in

Figure 2-3).

2.4 DIAGNOSTIC MESSAGES

Whenever a warning or fault has been triggered, diag-

nostic messages are displayed to aid in problem solv-

ing. These messages flash alternately with the

temperature reading.

If more than one message has been generated, the

warning or fault messages will alternate with the regular

readings.

See Section 6.0 Diagnosis and Troubleshooting for

message meaning and possible causes.
