MODEL 5081-C-FF/FI WIRING

WIRING THROUGH A JUNCTION BOXThe sensor can be wired to the analyzer through a remote junction box (PN 23550-00). Wire the extension cableand sensor cable point-to-point. Refer to the sensor instruction manual for more details.

Factory-terminated (PN 23747-00) and unterminated (PN 9200275) connecting cable are available. The use of fac-tory-terminated cable is strongly recommended. To prepare unterminated cable for use, follow the instructions inthe sensor instruction manual.

For maximum EMI/RFI protection, the outer braid of the sensor cable should be connected to the outer braidedshield of the extension cable. At the instrument, connect the outer braid of the extension cable to earth ground.

POWER WIRINGFor general purpose areas, wire poweras shown in Figure 3. For hazardousareas, please see hazardous areainstallation drawings.

FIGURE 3. Power Supply/Current Loop Wiring for Model 5081-C-FF/FI

WIRING

Wire sensor as shown below in Figure 2. Keep sensor wiring separate from power wiring. For best EMI/RFI protec-

tion, use shielded output signal cable in an earth-grounded metal conduit. Refer to the sensor instruction manual

for more details.

UNPACKING AND INSPECTION

Inspect the shipping container. If it is damaged, contact the shipper immediately for instructions. Save the box. If

there is no apparent damage, unpack the container. Be sure all items shown on the packing list are present. If

items are missing, notify Rosemount Analytical immediately.

ROTATING THE DISPLAY

The Model 5081-C-FF/FI display can be rotated 90° left or right. Disengage the cover lock and remove the front

cover. Remove the three screws holding the PCB stack and gently lift the display board. Do not disengage the rib-

bon cable between the display board and the CPU board. Rotate the display. The black infrared sensor will be at

the top of the display.

INSTALLATION

See Figure 4.

1. Although the analyzer is suitable for outdoor use, do not install it in direct sunlight or in areas of extreme tem-

peratures.

2. Install the analyzer in an area where vibrations and electromagnetic and radio frequency interference are mini-

mized or absent.

3. Keep the analyzer and sensor wiring at least one foot from high voltage conductors. Be sure there is easy

access to the analyzer.

4. The conduit connections on the sides of the 5081 housing should be sealed to prevent moisture from entering

the enclosure.

5. The transmitter must not be mounted with both conduit openings at the top.

QUICK-START

1. On the Remote, press PROG, NEXT, ENTER.

2. Use the arrow buttons to select COnduc (conductivity),

rStvtY (resistivity), or CuSt (custom curve) mode. Press

ENTER. If you chose ConduC or rStvtY, go to step 4.

3. If you selected CuST, you will see the Setup Custom

screen. To move to the custom curve configuration

menu, press ENTER. You will automatically return to

this same Setup Custom screen after configuration is

complete. To continue transmitter display programming,

press NEXT in the Setup Custom screen.

4. Use the arrow keys to toggle temperature units between

Celsius and Farenheit.

5. Press ENTER then RESET.

6. Press PROG, ENTER.

7. Use the arrow key to toggle t AutO to On or OFF to

select using either the process temperature (tAutO =

On) or a manual temperature (tAutO = OFF). Press

ENTER. If you selected t AutO = OFF, you will be

prompted to enter the manual temperature; use the

arrow keys, then press ENTER.

8. If you selected CondUC or rStvtY in step 2, you will see

a COMP (Temperature Compensation type) screen.

Use the arrow keys to select desired temperature com-

pensation: LinEAr (linear), n SALt (neutral salt),

CatIOn (cation conductivity), or nOnE (raw or uncom-
