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”.
