1.2 MECHANICAL INSTALLATIONThe Model 4081 T Transmitter is suitable for installation inharsh environments.

• For best operation, locate in an area where tempera-ture extremes, vibrations, electromagnetic, and radiofrequency interferences are minimized or absent.

The transmitter is equipped with two 3/4 in. FNPT conduitopenings, 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 sensorwiring, and the right side conduit opening for powersupply/current loop wiring.

• To prevent moisture from entering the transmitterhousing, use weathertight cable glands supplied byothers.

NOTEMoisture accumulation in the transmitterhousing can affect transmitter performanceand 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 inthe terminal side of the housing.

• The transmitter must be installed so that the conduitopenings are not on the top, because moisture canaccumulate in that position.

• The transmitter should be easily accessed by operatingand maintenance personnel.

1.2.1 Flat Surface Mounting. The transmitter may bemounted 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 mountingbracket is available. See Figure 1-3 for mounting information.

2.3 INFRARED REMOTE CONTROL (IRC)The IRC is the most convenient way to calibrate, pro-gram, or access the diagnostics in the transmitter. Itoperates the same as other remote controllers.

For best operation, the IRC should be within six feet ofthe transmitter and aimed directly at the infrared sensorwindow (small square window at top of display) at anangle of no more than fifteen degrees. The amount ofambient 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 theactive menu segment highlighted as described inSection 2.2.

2.3.2. Menu Keys. The three primary menu structuresare Calibrate (CAL), Program (PROG), and Diagnose(DIAG). They are shown horizontally on the screen andhave separate keys on the IRC (see 1, 2, and 3 in Figure2-3). Pressing the labeled key will provide access to thatmenu.

2.3.3. Program Command Keys. The three programcommand keys are labeled ENTER, NEXT, and EXIT(see 4, 5, and 6 in Figure 2-3). These keys are used asfollows:

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 inputvariables (see Figure 2-3). The left/right arrows changethe location of the prompt and causes the integer toflash. These also allow access to the measurement unitand decimal place location. When a flashing mnemonicappears on the display, the UP and DOWN arrow keysscroll up or down through the list. When numbers areshown, the UP and DOWN keys change the value ofthe digit.

6.4 QUICK TROUBLESHOOTING GUIDE

TABLE 6-3. Quick Troubleshooting Guide.

When it is apparent by grab sample analysis that thetransmitter is giving inaccurate readings, the following pro-cedure should be followed.

A. A quick visual inspection of the installation may identifythe problem. Check to be sure that the transmitter ismounted securely and that its internal parts are proper-ly connected.

B. Recheck to ensure the power supply is connected tothe correct pins in the transmitter and that power isbeing received.

C. Check the sensor to transmitter terminal wiring and thatall connections are tight. Most error messages are gen-erated by incorrect wiring and will indicate if the RTD orthe toroid are connected incorrectly.

D. The sensor must be immersed into the process streamto the top of the toroid.

E. Verify that the sensor is clean and the process is flow-ing through and around the toroid.
