EMERSON Rosemount 3408 Level Transmitter Non-Contacting Radar

About this guide

This Quick Start Guide provides basic guidelines for the Rosemount 3408 Level Transmitter. Refer to the 3408 Reference Manual for more instructions.

Safety messages

• Failure to follow safe installation and servicing guidelines could result in death or serious injury.
• Ensure the transmitter is installed by qualified personnel and in accordance with applicable code of practice.
• Use the equipment only as specified in this Quick Start Guide and the Reference Manual. Failure to do so may impair the protection provided by the equipment.
• For installations in hazardous locations, the transmitter must be installed according to the Rosemount 3408 Product Certifications document and System Control Drawing.
• Repair, e.g. substitution of components, etc. may jeopardize safety and is under no circumstances allowed.

WARNING

• Explosions could result in death or serious injury.
• Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.
• Before connecting a handheld communicator in an explosive atmosphere, ensure the instruments are installed in accordance with intrinsically safe or non-incendive field wiring practices.
• In Explosion-proof/Flameproof and Non-Incendive/Type Ex ec installations, do not remove the transmitter cover when power is applied to the unit.
• The transmitter cover must be fully engaged to meet Explosion-proof/Flameproof requirements.

WARNING

Electrical shock could cause death or serious injury. Ensure the mains power to the transmitter is off and the lines to any other external power source are disconnected or not powered while wiring the transmitter.

WARNING

Process leaks could result in death or serious injury. Ensure that the transmitter is handled carefully. If the process seal is damaged, gas might escape from the tank.

WARNING

Physical access Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

CAUTION

Hot surfaces The flange and process seal may be hot at high process temperatures. Allow to cool before servicing.

Confirm approval type

For hazardous locations transmitters labeled with multiple approval types:

Procedure

Permanently mark the checkbox of the selected approval type.

Mount the process seal antenna

Mount the flanged version

Procedure

1. Lower the transmitter into the nozzle.
   Note Be careful not to scratch or otherwise damage the PTFE sealing.

2. Tighten the bolts and nuts (see Table 3-1).
   Note

3. Re-tighten after 24 hours and again after the first temperature cycle.

4. Check at regular intervals and re-tighten if necessary.

5. Torque specifications
   The conditions used for the calculation are:

6. Standard mating metal flange

7. A193 B8M Cl.2 / A4-70 bolt material

8. Friction coefficient of μ=0.16
   Low strength bolt and non-metallic mating flange may require lower tightening torque.

   Example

2. (A) Threaded fitting

3. (B) Threaded flange

4. Mount the transmitter on the tank
   Note Be careful not to scratch or otherwise damage the PTFE sealing

Mount the ATAP lens antenna

Open air installations

The antenna extension must be fitted to the transmitter to comply with open air requirements.

Figure 5-1: Antenna Extension

Mount the bracket

Prerequisites Mount the bracket so that it is not susceptible to vibration.

Procedure

1. Mount the bracket to the pipe/wall.
   Example

2. Mount the adapter.

3. Secure the transmitter to the adapter.

Procedure

1. Place a suitable gasket on the tank nozzle.
   Example

2. (A) Threaded fitting

3. (B) Threaded flange

4. Mount the transmitter on the tank.

Rotate the transmitter housing

To improve field access to wiring or to better view the optional LCD display:

Procedure

1. Loosen the set screw.
2. Rotate the transmitter housing to the desired location, and then retighten the set screw.

Prepare the electrical connections

Cable selection

Use 24-16 AWG wire (0.20-1.5 mm2). Twisted pairs and shielded wiring are recommended for environments with high EMI (electromagnetic interference).
Fine stranded conductors shall be equipped with a ferrule.

Cable gland/conduit

For explosion-proof/flameproof installations, only use cable glands or conduit entry devices certified explosion-proof or flameproof.

Internal power consumption

< 0.8 W in normal operation

Grounding

Make sure grounding is done according to national and local electrical codes. Failure to do so may impair the protection provided by the equipment.

Transmitter housing

The most effective grounding method is direct connection to earth ground with minimal impedance. There are two grounding screw connections provided (see Figure 7-1).

Cable shield grounding

Make sure the instrument cable shield is:

• Trimmed close and insulated from touching the transmitter housing.
• Continuously connected throughout the segment.
• Connected to a good earth ground at the power supply end

Figure 7-2: Cable Shield

• A. Insulate shield and drain wire
• B. Minimize distance
• C. Trim shield and insulate exposed drain wire
• D. Connect drain wire to the power supply ground

Note
Do not ground the shield and its drain wire at the transmitter. If the cable shield touches the transmitter housing, it can create ground loops and interfere with communications.

Power supply

The transmitter operates on max. 35 Vdc transmitter terminal voltage and max. 22.5 mA (max. 30 Vdc in Intrinsically Safe installations).

Load limitations

For HART® communication, a minimum loop resistance of 250 Ω is required. Maximum loop resistance (R) is determined by the voltage level of the external power supply (UE):

• A. Handheld communicator
• B. Approved IS barrier (for Intrinsically Safe installations only)
• C. HART modem
• D. Load resistance (≥250 Ω)
• E. Current meter
• F. Power supply

Connect wiring and power up

Procedure

1. Verify the power supply is disconnected.

2. Remove the cover.

3. Remove the LCD display (if fitted).

4. Remove the plastic plugs

5. Pull the cable through the cable gland/conduit. Identification of thread size and type

6. Connect the cable wires.
   Note When connecting a flexible (stranded) conductor, use a small screwdriver to press down and hold the terminal connection open

7. Ensure proper grounding

8. Tighten the cable gland. Apply PTFE tape or other sealant to the threads.
   Note Make sure to arrange the wiring with a drip loop.

9. Seal any unused port with the enclosed metal plug. Apply PTFE tape or other sealant to the threads

10. Snap the LCD display into place.

11. Attach and tighten the cover.

12. Verify the cover jam screw is completely threaded into the housing.

13. Attach and tighten the cover
    Note Make sure the cover is fully engaged. There should be no gap between the cover and the housing.

14. Turn the jam screw counterclockwise until it contacts the cover.
    Note Required for explosion-proof/flameproof installations only

15. Turn the jam screw an additional ½ turn counterclockwise to secure the cover.

16. Connect the power supply.
