1 About this guide
This Quick Start Guide provides basic guidelines for the Rosemount™ 2140
and 2140:SIS Level Detectors. Refer to the Rosemount 2140 and 2140:SIS
Reference Manual for more instructions. The manual and this guide are also
available electronically at Emerson.com/Rosemount.
WARNING
Failure to follow safe installation and servicing guidelines could result in
death or serious injury.
•Ensure the level detector is installed by qualified personnel and in
accordance with applicable code of practice.
•Use the level detector only as specified in this manual. Failure to do so
may impair the protection provided by the level detector.
•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.
•For installations in hazardous locations, the level detector must be
installed according to the Rosemount™ 2140 and 2140:SIS Level
Detectors Product Certifications document
Explosions could result in death or serious injury.
•Verify that the operating atmosphere of the level detector is consistent
with the appropriate hazardous locations certifications.
•Before connecting a handheld communicator in an explosive
atmosphere, ensure that the instruments in the loop are installed in
accordance with intrinsically safe or non-incendive field wiring practices.
•In explosion-proof/flameproof and non-incendive/type n installations, do
not remove the housing covers when power is applied to the level
detector.
•Both housing covers must be fully engaged to meet flameproof/
explosion-proof requirements.

WARNING
Electrical shock could cause death or serious injury.
•Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.
•Ensure the power to the level detector is off, and the lines to any other
external power source are disconnected or not powered while wiring the
level detector.
•Ensure the wiring is suitable for the electrical current and the insulation is
suitable for the voltage, temperature, and environment.
Process leaks could result in death or serious injury.
•Ensure the level detector is handled carefully. If the process seal is
damaged, gas might escape from the vessel (tank) or pipe.
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.

2.6 Adjust display orientation (optional)
To improve field access to wiring or to better view the optional LCD display:
Procedure
1. Loosen the set screw until the level detector housing can rotate
smoothly.
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 thread limit, rotate
the housing counterclockwise.
3. Re-tighten the set screw.

3 Prepare the electrical connections
Note
See the Rosemount 2140 Product Data Sheet for all electrical specifications.
3.1 Cable selection
Use 24–14 AWG wiring. Twisted-pairs and shielded wiring is recommended
for environments with high EMI (electromagnetic interference). Two wires
can be safely connected to each terminal screw.
3.2 Cable glands/conduits
For intrinsically safe, explosion-proof/flameproof, and dust-proof
installations, only use certified cable glands or conduit entry devices.
Ordinary location installations can use suitably rated cable glands or conduit
entry devices to maintain the Ingress Protection (IP) rating.
Unused conduit entries must always be sealed with a suitably rated
blanking/stopping plug.
Note
Do not run signal wiring in conduit or open trays with power wiring or near
heavy electrical equipment.
3.3 Power supply
Each level detector operates on 10.5 – 42.4 Vdc (10.5 – 30 Vdc in
Intrinsically Safe installations) at the level detector terminals.
3.4 Power consumption
Maximum of 1 W, and current maximum is 23 mA.
3.5 Hazardous areas
When the level detector is installed in hazardous areas (classified locations),
local regulations and the conditions-of-use specified in applicable
certificates must be observed. Review the Rosemount 2140 Product
Certifications document for information.
3.6 Load limitations
For HART® communications, a minimum load resistance of 250 Ω is
required.
The maximum loop resistance is determined by the voltage level of the
external power supply (see Figure 3-1).
