ATTENTION
Safety Instructions
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.

Power Supply
Supply voltage
• DC voltage version 12…30 V DC
Current consumption
• Without load < 60 mA, with reverse polarity protection
Power supply failure
• Behavior in case of overvoltage (> 30 V) The device works continuously up to 34V DC without any damage. No damage is caused to the device in case of a short-term overvoltage up to 1 kV (as per EN 61000-4-5). If the supply voltage is exceeded, the properties specified are no longer guaranteed.
• Behavior in case of undervoltage If the supply voltage drops below the minimum value, the device switches off (status as if not supplied with power = switch open).
Output
Switching capacity
• Switch status ON: I
• Switch status OFF: I
• Switching cycles: > 10,000,000
• Voltage drop PNP: 2 V
• Overload protection Automatic load testing of switching current; output is switched off in case of overcurrent, the switching current is tested again every 0.5 sec.; max. capacitance load: 14 F for max. supply voltage (without resistive load).
