1 About this guide
This Quick Start Guide provides basic guidelines for the Rosemount 2110.
Refer to the Rosemount 2110 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 switch is installed by qualified personnel and in
accordance with applicable code of practice.
•Use the level switch only as specified in this manual. Failure to do so may
impair the protection provided by the level switch.
Explosions could result in death or serious injury.
•The level switch must only be installed and operated in non-hazardous
(ordinary) locations.
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 switch is off, and the lines to any other
external power source are disconnected or not powered while wiring the
level switch.
•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 switch is handled carefully. If the process seal is
damaged, gas might escape from the vessel (tank) or pipe.

WARNING
Any substitution of non-recognized parts may jeopardize safety. Repair (e.g.
substitution of components) may also jeopardize safety and is not allowed
under any circumstances.
•Unauthorized changes to the product are strictly prohibited as they may
unintentionally and unpredictably alter performance and jeopardize
safety. Unauthorized changes that interfere with the integrity of the
welds or flanges, such as making additional perforations, compromise
product integrity and safety. Equipment ratings and certifications are no
longer valid on any products that have been damaged or modified
without the prior written permission of Emerson. Any continued use of
product that has been damaged or modified without the written
authorization is at the customer’s sole risk and expense.
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.

3 Prepare the electrical connections
Note
See the Rosemount 2110 Product Data Sheet for all electrical specifications.
3.1 Cable selection
Twisted-pairs and shielded wiring is recommended for environments with
high EMI (electromagnetic interference). Two wires can be safely connected
to each terminal screw. Maximum wire size is 15 AWG.
3.2 Cable glands/conduits
The cable gland is integrated in the four-position plug of the level switch. Do
not make any modifications to the level switch.
3.3 Power supply
The Direct Load electronics operate on 21 - 264 Vdc or 21 - 264 Vac (50/60
Hz) at the level switch terminals.
The PNP electronics operate on 18 - 60 Vdc at the level switch terminals.
3.4 Mode selection
Table 3-1 shows how the mode selection is determined from the wiring
connections. Modes are “Dry on, high level alarm” and “Wet on, low level
alarm”.

5.6 Instructions for hygienic installations
The following instructions are for a Rosemount™ 2110 Level Switch (“level
switch”) with a 51 mm Tri Clamp fitting covered by 3-A authorization 3632
and EHEDG certificate 102016, and ASME-BPE and FDA compliance:
1. The level switch is suitable for installation on pipeline (with fork gap
in line with the flow) and on closed vessels (with the fork gap
vertical).
EHEDG only recommend horizontal stub mounting in pipelines:
OK OK
2. Installation of this equipment shall be carried out by suitably trained
personnel, in accordance with the applicable code of practice.
3. Inspection and maintenance of this equipment shall be carried out by
suitably trained personnel, in accordance with the applicable code of
practice.
4. If the level switch is installed in a stub then, to ensure clean-ability,
the length (L) must not exceed the diameter (D) with a minimum
diameter (D) of 46 mm.

5. The certification of the level switch relies upon the following
materials used in its construction:
a. Product contact surfaces
Probe: Stainless steel 316/316L
b. Non-product contact surfaces
Enclosure: Stainless steel 304 type
Lens: Nylon 12
Seals: Nitrile rubber

and cleaning (sanitisation) processes.
b. The installation of the level switch is drainable and cleanable.
c. That the joint requirements between the probe and the
vessel/pipe are compatible with the process media,
applicable standards, and code of practice. In EHEDG
applications, the seals (gaskets) used should be as defined in
the EHEDG position paper “Easy cleanable pipe couplings and
process connections”.
7. Cleaning-In-Place (CIP) routines up to 160 °F (71 °C) are suitable for
the level switch.
