Safety Instructions

1 Safety Instructions

1. 1 Designated Use

The Bulletin 836E is a pressure switch for measuring and monitoring absolute and gauge pressures. 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.

1. 2 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836E pressure switch. Failure to comply may result in personal injury and/or equipment damage.

1. 3 Operational Safety

• Functional safety The Bulletin 836E pressure switches were developed according to the standards IEC61508 and IEC 61511-1 (FDIS).

• Hazardous areas The Bulletin 836E is not approved for use in intrinsic safety (hazardous area) applications.

1. 4 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.

ATTENTION: 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.

• The series number indicates the version of the switch. A change in the series letter does not

have any effect on the compatibility (see also Section 6 — Troubleshooting).

• The MWP (maximum working pressure) is specified on the nameplate. This value refers to

a reference temperature of +20 °C (68 °F) and may be applied to the device for an unlimited time.

• The test pressure (Over Pressure Limit [OPL]) corresponds to 1.5 times the MWP and may

be applied only for a limited time before causing damage to the switch.

3. 3 Installation Instructions

Fig. 3: Typical applications of the Bulletin 836E to measure pressure in gases, steam and liquids.

➀ Bulletin 836E pressure switch ➁ Shut-off assembly ➂ U-pipe

For typical applications of the Bulletin 836E, see Figure 3 above:

• The image on the left illustrates how the 836E should be applied for pressure measurement in gases. The switch should be mounted with a shut-off assembly above the sampling nozzle so that any condensate can drain off into the process.

• The center image shows the correct installation for pressure measurement in steam. Note how the Bulletin 836E is mounted with a U-pipe below the sampling nozzle. Fill the U-pipe with fill fluid before commissioning.

• For pressure measurement in liquids, see the drawing on the right of Figure 3 above. The Bulletin 836E should be mounted below or at the same level as the sampling nozzle.

Additional considerations:

• Do not mount the device in the product flow or at a point where it could be affected by pressure pulses.

• Calibration and testing are easier if the device is mounted downstream of a shut-off assembly.

• The orientation of the Bulletin 836E can result in zero point shift, i.e. the measured value does not display zero in a non-pressurized state. This zero point shift can be corrected (see Section4 – Operation).

• The digital display can be electronically rotated 180° (see Section 4 – Operation).

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