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.
WARNING
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 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.

WARNING
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.
CAUTION
The products described in this document are NOT designed for nuclear-qualified applications.
Using non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause inaccurate
readings.
For information on Rosemount nuclear-qualified products, contact your local Emerson Sales Representative.

1.1 About this document
This document provides information about how to install, commission, and proof test a
Rosemount 2140:SIS Level Detector to comply with Safety Instrumented Systems (SIS)
requirements.
Note
The following conditions must apply:
• The level detector has been installed correctly and completely according to the
instructions in the Reference Manual and Quick Start Guide.
• The installation complies with all applicable safety requirements.
• The operator is trained in local and corporate safety standards.
1.2 About this product
The Rosemount 2140:SIS Level Detector consists of a tuned fork with a driver and receiver
element, and integral interface electronics. The level detector is based on the principle
that the resonant frequency of a tuned fork changes when it is immersed in a liquid. The
frequency change is detected and used to switch an electronic output. The device output
is 4-20 mA.

2 Installation and commissioning
2.1 Safety Instrumented System (SIS) certification
For safety instrumented systems usage, the 4-20 mA analog output is used as the primary
safety variable. It is configured to activate the alarm function if an error occurs. The
Rosemount 2140:SIS may be used in high level or low level safety related applications.
The measurement signal used by the logic solver must be the discrete current levels set at
the instrument output used to indicate the sensor condition. A change in liquid level
through the switch point of the level detector results in the user configured discrete
current value being set at the output by the instrument. The HART® protocol must only be
used for setup, calibration, and diagnostic purposes, not for safety critical operation.
The Rosemount 2140:SIS is IEC 61508 certified to:
• Type B low-demand device
• SIL 2 @ HFT = 0
• SIL 3 @ HFT = 1
2.2 Safety certified identification
All Rosemount 2140:SIS Level Detectors must be identified as safety certified before
installing into SIS systems.
Procedure
1. Verify the model code starts with "2140F".
2.
Verify the software (SW) is V01.01.00 or later.
