837E Solid-State Temperature Sensors User Manual

ATTENTION

Safety Instructions

Designated Use

The Bulletin 837E is a temperature switch for measuring and monitoring, displaying and regulating process temperatures. The device has been safely built with state-of-the-art technology and meets the applicable requirements and EC Directives. It can, however, be a source of danger if used incorrectly or for anything other than the designated use.

Installation, Commissioning, and Operation

Only personnel familiar with these types of products and associated machinery should plan or implement the installation, start-up, configuration, and subsequent maintenance of the Bulletin 837E temperature switch. Failure to comply may result in personal injury and/or equipment damage.

Operational Safety

Functional Safety

The Bulletin 837E temperature switches were developed according to the standards IEC 61508 and IEC 61511-1 (FDIS). The 837E version with PNP switch output and additional analog output is equipped with fault detection and fault prevention functions within the electronics and software. This switch version can therefore be used to monitor temperatures in applications up to Safety Integrity Level 2 (SIL2).

Hazardous Areas

The Bulletin 837E is not approved for use in intrinsic safety (hazardous area) applications.

Return

Before returning a device to Rockwell Automation, be sure to remove all fluid residue. This is particularly important if the fluid is a health hazard, e.g. flammable, toxic, caustic, carcinogenic, etc.

Do not return a measuring device if you are not absolutely certain that all traces of hazardous substances have been removed, e.g. substances which have penetrated crevices or diffused through plastic.

Mounting instructions:

• Item A: Installation at angle pieces, against the direction of flow

• Item B: Installation in smaller pipes, inclined against the direction of flow

• Item C: Installation vertical to the direction of flow (see Figure 2, Item C). Installation of 837E by minimum of 3° inclination because of self draining.

• The digital display can be electronically rotated 180°—see “Operation” section.

• The housing can be rotated up to 310° for optimal readability and ease of wiring.

• Care should be taken by the user in the execution of the welding on the process side:

• Suitable weld material

• Flush welding or with welding radius > 3.2 mm.

• Absence of pits, folds, crevices.

• Ground and polished surface (R As a general rule, the thermometers should be installed in such a way that does not

adversely affect their cleanability.
