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.
