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.

• 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.

The hysteresis mode enables two-point control via a hysteresis. Depending on the
temperature T, the hysteresis can be set via the switch point SP and the reset point RSP.
• Window mode
The window mode allows for the monitoring of a temperature range.
• Analog output mode
The analog output mode returns a 4…20mA signal proportional to the measured value.
The upper and lower range values can be set by the user.

If an error occurs in the electronics, the color of the status LED changes from green to red
and the display shows an error or warning code, as outlined below:

In the event of an error message, the measured value is unreliable.
• W-code for warnings
In the event of a warning, the measured value is still reliable.

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).
