1 About this guide

This Quick Start Guide provides basic guidelines for the Rosemount 2130.Refer to the Rosemount 2130 Reference Manual for more instructions. Themanual and this guide are also available electronically at Emerson.com/Rosemount.

WARNING

Failure to follow safe installation and servicing guidelines could result indeath or serious injury.

• Ensure the level switch is installed by qualified personnel and inaccordance with applicable code of practice.

• Use the level switch only as specified in this manual. Failure to do so mayimpair the protection provided by the level switch.

• The weight of a level switch with a heavy flange and extended fork lengthmay exceed 37 lb. (18 kg). A risk assessment is required before carrying,lifting, and installing the level switch.

Explosions could result in death or serious injury.

• Verify that the operating atmosphere of the level switch is consistentwith the appropriate hazardous locations certifications.

• Before connecting a handheld communicator in an explosiveatmosphere, ensure that the instruments in the loop are installed inaccordance with intrinsically safe or non-incendive field wiring practices.

• In explosion-proof/flameproof and non-Incendive/type n installations, donot remove the housing cover when power is applied to the level switch.

• The housing cover must be fully engaged to meet flameproof/explosion-proof requirements.

Electrical shock could cause death or serious injury.

• Avoid contact with the leads and terminals. High voltage that may bepresent on leads can cause electrical shock.

• Ensure the power to the level switch is off, and the lines to any otherexternal power source are disconnected or not powered while wiring thelevel switch.

• Ensure the wiring is suitable for the electrical current and the insulation issuitable for the voltage, temperature, and environment.

WARNING

Process leaks could result in death or serious injury.

• Ensure the level switch is handled carefully. If the process seal isdamaged, gas might escape from the vessel (tank) or pipe.

Any substitution of non-recognized parts may jeopardize safety. Repair (e.g.substitution of components) may also jeopardize safety and is not allowedunder any circumstances.

• Unauthorized changes to the product are strictly prohibited as they mayunintentionally and unpredictably alter performance and jeopardizesafety. Unauthorized changes that interfere with the integrity of thewelds or flanges, such as making additional perforations, compromiseproduct integrity and safety. Equipment ratings and certifications are nolonger valid on any products that have been damaged or modifiedwithout the prior written permission of Emerson. Any continued use ofproduct that has been damaged or modified without the writtenauthorization is at the customer’s sole risk and expense.

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/ormisconfiguration of end users’ equipment. This could be intentional orunintentional and needs to be protected against.

Physical security is an important part of any security program andfundamental to protecting your system. Restrict physical access byunauthorized personnel to protect end users’ assets. This is true for allsystems used within the facility.

CAUTION

Hot surfacesThe flange and process seal may be hot at high processtemperatures.

Allow to cool before servicing.

3 Prepare the electrical connections

NoteSee the Rosemount 2130 Product Data Sheet for all electrical specifications.

3.1 Cable selectionUse 26–14 AWG (0.13 to 2.5 mm2 wiring. Twisted-pairs and shielded wiringis recommended for environments with high EMI (electromagneticinterference). Two wires can be safely connected to each terminal screw.

3.2 Cable glands/conduitsFor intrinsically safe, explosion-proof/flameproof, and dust-proofinstallations, only use certified cable glands or conduit entry devices.Ordinary location installations can use suitably rated cable glands or conduitentry devices to maintain the Ingress Protection (IP) rating.

Unused conduit entries must always be sealed with a suitably ratedblanking/stopping plug.

NoteDo not run signal wiring in conduit or open trays with power wiring or nearheavy electrical equipment.

3.3 Power supplyThe power supply requirements are dependent on the electronics selected.

• Direct Load electronics: 20 - 264 Vdc or 20 - 264 Vac (50/60 Hz).

• PNP electronics: 18 - 60 Vdc

• Standard Relay electronics: 20 - 264 Vdc or 20 - 264 Vac (50/60 Hz)

• NAMUR electronics: 8 Vdc

• 8/16 mA electronics: 24 Vdc

• Fault and Alarm Relays: 20 - 264 Vdc or 20 - 264 Vac (50/60 Hz)

3.4 Hazardous areasWhen the level switch is installed in hazardous areas (classified locations),local regulations and the conditions-of-use specified in applicablecertificates must be observed. Review the Rosemount 2130 ProductCertifications document for information.

3.6 Grounding

Always ground the housing in accordance with national and localelectrical codes.

3.6.1 Grounding using the cable shield

Make sure the instrument cable shield is:

• Trimmed close and insulated from touching the level switch housing.

• Continuously connected throughout the segment.

• Connected to a good earth ground at the power supply end.

Procedure

1. Verify the power supply is disconnected.

2. Remove the field terminals cover.

In an explosion-proof/flameproof installation, do not remove thelevel switch cover when power is applied to the unit. The cover mustalso not to be removed in extreme environmental conditions.

• Versions of the Rosemount 2130 with explosion-proof/flameproof approvals have a cover-lock to be undone first.

3. Remove the plastic plugs.

4. Pull cables through the cable gland/conduits.

• Cassettes with a single terminal only require one cable.

5 Configuration

5.1 Set the mode and time delay for the outputAll electronics cassettes have a rotating switch for setting the electricaloutput to be on when the fork is sufficiently dry ("Dry On") or when the fork issufficiently wet ("Wet On").

The electronics uses hysteresis to help prevent constant switching of theoutput due to splashing or intermediate conditions. To further prevent thisconstant switching, the rotating switch also sets a time delay of up to 30seconds before the output changes.

A small cut-out on the rotating switch indicates the present mode and timedelay.

The recommended mode for high level alarm installations is the "Dry On"mode (Figure 5-2). The "Wet On" mode is recommended for low level alarminstallations (Figure 5-3).

NoteThere is a five second delay before changes to the mode and time delaybecome active.
