EMERSON 3490 Rosemount Controller User Guide

About this guide

This Quick Start Guide provides basic guidelines for the Rosemount 3490 Controller. Refer to the Rosemount 3490 Reference Manual for more instructions.

Safety messages

WARNING
Failure to follow safe installation and servicing guidelines could result in death or serious injury.
Use the controller only as specified in this Quick Start Guide and the Reference Manual.
The controller must be installed, connected, commissioned,

operated, and maintained by suitably qualified personnel only, observing national and local requirements that may apply.

The controller must be installed according to the Rosemount 3490 Product Certifications document.

Before commissioning the controller, ensure that the supply voltage matches the voltage specifications on the main label.

Repair, e.g. substitution of components, etc. may jeopardise safety and is under no circumstances allowed.

Electrical shock could cause death or serious injury.
Ensure that the controller is not powered when opening the lid and making terminal connections.

If the controller is installed in a high voltage environment and a fault condition or installation error occurs, high voltage may be present on leads and terminals.

WARNING

Physical access
Unauthorised personnel may potentially cause significant damage to and/or reconfiguration 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 in protecting your system. Restrict physical access by unauthorised personnel to protect end users’ assets. This is true for all systems used within the facility.

CAUTION

Pollution protection
Ensure that during installation or maintenance no moisture or dirt can get inside the instrument.
To maintain the housing protection, ensure that the housing lid is closed during operation and locked, if necessary.

Installation considerations

General

• The controller is classified type A in accordance with European EMC directive 2014/30/EU. To ensure electro-magnetic compatibility, in any member country, the controller should not be installed in a residential area.
• Supply circuits must be limited to Over voltage category II, according to IEC 60664-1.
• Ambient temperature range: -40 to +140 °F (-40 to +60 °C)(1)

Mounting and installation

• Do not mount the controller on a structure that is subject to vibration, or in a position where damage may be caused by impact, thermal stress or liquid ingress.
• Do not mount the controller in a position where it might come into contact with aggressive substances, e.g. acidic liquids or gases that may attack metals or solvents that may affect polymeric materials.
• The controller housing is rated IP66/IP67 and Type 4X. It is suitable for mounting outside, but this should be above any flood level, away from any overflow path, and away from direct sunlight.
• The mass of the unit is 3.7 lb (1.7 kg). To conform with safety requirements, the wall on which the unit is mounted should be capable of supporting four times this weight.
• Do not mount the controller in a position where it might be exposed to mechanical damage or friction. The controller can withstand an impact of maximum 2 Joule, level of protection: IK07.

Wiring

• Ensure that cable glands and connections to the controller are done in accordance with local and national standards. To maintain the type 4X rating of the enclosure, type 4X connections must be used.
• Cable runs should be separate from any high voltage or mains cables to avoid crosswalk or interference.
• A switch or circuit-breaker must be included in the installation, suitable located and easily reached. It must be marked as the disconnecting device for the controller.
• Wires for mains connection should be tied together to prevent from accidental loosening.
• Field wiring shall be rated for 38 °F (21 °C) above maximum ambient temperature.

Maintenance

• To ensure the controller functionality, periodic visual inspection is recommended for:
  • Secure mounting
  • No mechanical damages or corrosion
  • Worn or otherwise damaged cables

Prepare the electrical connections

Cable selection

The cable diameter must be suitable for the cable gland used to ensure the seal effect of the cable gland (IP protection).

Cable glands

The controller housing has seven entries for M20 cable glands.

Table 5-1: Tightening Torque for Cable Glands, lb-ft (Nm)

(1) Only supplied with accessory gland kit.

Table 5-2: Cable Diameter for Glands, in. (mm)

| Cable gland| Ethernet cable gland (1)
---|---|---
Cable Ø| 0.16-0.51 (4-13)| 0.27 (6.9)

(1) Only supplied with accessory gland kit.

Conduit hubs

The controller can be installed with conduit hubs. The conduit hub must be installed with a M20 to ½ NPT adapter mounted to the support plate. The adapter is available as accessories.

B. Cross-sectional area, see Table 5-4

Power supply

The Rosemount 3490 accepts supply voltage 100-240 Vac 50/60 Hz (-15% to +10%)

Power consumption

Maximum 12 W

Grounding
Make sure grounding is done according to national and local electrical codes. Failure to do so may impair the protection provided by the equipment. Grounding requirements are dependent on application type:

Shielded cables

• Connect cable shield to terminal 42 (terminal 71 for sensor input 2)
• Connect terminal 41 to instrument earth/ground point

Unshielded cables

Grounding is not necessary for unshielded sensor cables. Leave terminals 41, 42 and 71 unconnected.

Protective earth

The metal support plate should always be grounded in accordance with national and local electrical codes. Failure to do so may impair the protection provided by the equipment. The most effective grounding method is direct connection to earth ground with minimal impedance. There is a grounding screw connection on the metal support plate.

Sensor wire cross-section

Appropriate cross-sectional area of wires must be used in order to prevent a too high voltage drop to the connected sensor. Use 0.75 mm2 to 2.5 mm2 (18 AWG to 13 AWG) in order to minimize the voltage drop.
