Quick Start Guide for Installation
May 2017Quick Start Guide
1.0 About this guideThis Quick Start Guide provides basic guidelines for Rosemount 2140 and 2140:SIS Vibrating Fork Liquid Level Detectors (“level detectors”).
Refer to the Rosemount 2140 Reference Manual for more instructions, and the Rosemount 2140 Product Certifications Manual for approvals information and safety matters. Manuals are available electronically at Emerson.com/Rosemount.
1.1 Symbols used in this guide
1.2 Required equipmentStandard tools e.g. screwdrivers and wire strippers/cutters.
1.3 Contents
Failure to follow safe installation guidelines could result in death or serious injury.
Use the level detector only as specified in this guide and the product reference manual.
The level detector must be installed, connected, commissioned, operated, and maintained by suitably qualified personnel only, observing national and local requirements that may apply.
The weight of a level detector with a heavy flange and extended fork length may exceed 37 lb. (18 kg).A risk assessment is required before carrying, lifting, and installing the level detector.
Explosions could result in death or serious injury.
Refer to the Rosemount 2140 Product Certifications Manual for restrictions associated with the intrinsically safe, explosion-proof/flameproof and dust approvals for this product.
Electrical shock could cause death or serious injury
Make sure that the level detector is not powered when removing the terminal cover and making terminal connections.
If the level detector is installed in a high voltage environment and a fault condition or installation error occurs, high voltage may be present on leads and terminals.
External surfaces may be hot.
Care must be taken to avoid possible burns. The flange and process seal may be hot at high process temperatures. Allow to cool before servicing.
Refer to the Rosemount 2140 Reference Manual for further information.

3.0 Adjust display orientation (optional)To improve field access to wiring or get a better view of the optional LCD display:1. Loosen the set screw until the level detector housing can rotate smoothly.
a. Do not unscrew all the way. Rotating the housing, without this screw in place, can damage the internal wiring.
2. First, rotate the housing clockwise to the desired location.
If the desired location cannot be achieved due to the internal thread limit, rotate the housing counterclockwise.
3. Re-tighten the set screw.
H3/32 in.Torque 30 in-lb (3 Nm)
Do not attempt to rotate the display beyond the thread limits.

4.0 Prepare the electrical connections
4.1 Cable selectionUse 24-14 AWG wire. Twisted-pairs and shielded wiring is recommended for environments with high EMI (electromagnetic interference). Two wires can be safely connected to each terminal screw.
4.2 Cable gland/conduitFor intrinsically safe, explosion-proof/flameproof, and dust-proof installations, use the supplied blanking plug and a suitably certified cable gland/conduit entry device(s).
4.3 Power supplyThe level detector operates on 10.5 - 42.4 Vdc (10.5 - 30 Vdc in intrinsically safe installations) at the level detector terminals.
4.4 Power consumptionMaximum of 1 W, current maximum 23 mA.
4.5 Load limitationsFor HART® communication, a minimum load resistance of 250 Ù is required.
The maximum loop resistance is determined by the voltage level of the external power supply, as described in Figure 3.

Step 5: Ensure proper groundingMake sure grounding is done according to national and local electrical codes. Failure to do so may impair the protection provided by the equipment.
Transmitter case grounding
The most effective grounding method is direct connection to earth ground with minimal impedance (< 1 ). Use either internal or external grounding screw.
Figure 5. Ground Screws
A. External ground screwB. Internal ground screw
Signal cable shield grounding
Make sure the instrument cable shield is: Trimmed close and insulated from touching the level detector housing. Connected to the next shield if cable is routed through a junction box. Connected to a good earth ground at the power supply end.

Step 8: Attach and tighten the covers1. Verify the cover jam screws are completely threaded into the housing.
2. Attach and tighten the covers. Make sure the covers are fully engaged.
3. Required for explosion-proof/flameproof and dust-proof installations only:a. Turn the cover jam screw counterclockwise until it contacts the cover.b. Turn the jam screw an extra 1/2 turn counterclockwise to secure the cover.

Step 9: Connect the power supplyIt may take up to 15 seconds before the LCD display lights up.
6.0 Confirm system readiness
6.1 Confirm HART revision capabilityIf using HART-based control or asset management systems, confirm the HART 7 capability of such systems prior to commissioning and installation. Not all systems are capable of communicating with the HART Revision 7 protocol. This level detector can be configured for either HART Revision 5 or 7.
6.2 Confirm correct device driver Verify that the correct Device Driver (DD) or Device Type Manager (DTM) is
loaded on your systems to ensure proper communication. Download the DD/DTM from Emerson.com/Rosemount.
6.3 Change HART revision modeIf the HART configuration tool is not capable of communicating with HART Revision 7, the device will load a generic menu with limited capability.
To change the HART revision mode from the generic menu:1. Go to Manual Setup > Device Information > Identification > Message.
2. In the Message field, enter “HART5” or “HART7” and then 27 trailing spaces.
7.0 Configure level detector using Guided SetupThe Rosemount 2140 and Rosemount 214:SIS can be configured using a Field Communicator, a PC running the AMS Device Manager, or any other Device Descriptor (DD) compatible host system.
7.1 AMS Device Manager1. Start AMS Device Manager.
2. Select View > Device Connection View.
3. In the Device Connection View, double-click the HART modem icon.
4. Double-click the device icon.
5. From the Home screen, select Configure > Guided Setup.
6. Select Basic Setup and follow the on-screen instructions.
7.2 Field Communicator1. Turn on the Field Communicator.
2. From the Main Menu, tap the HART symbol. The Field Communicator now connects to the device.
3. From the Home screen, select Configure > Guided Setup.
4. Select Basic Setup and follow the on-screen instructions.
