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.

11 Wiring diagram

• 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.

5.1.1 Adapter Change

The adapter can be changed on 836E.

Fig. 11: Changing the adapter

➀ Sensor module with adapter thread ➁ Standard O-ring ➂ Adapter

Please note the following when changing the adapter:

• Use a new O-ring. Diameter 15.54 x 2.62 mm (0.61 x 0.10 in.) with either EPDM 70 Shore FDA or FKM 70 Shore FDA material

• The sensor can be mounted with a 27 mm open-ended wrench.

• The adapter can be threaded on and tightened with a 28 or 32 mm (1.1 or 1.26 in.) open-ended wrench (depending on the process connection). The maximum torque is 80 N•m. The adapter can become loose if exposed to severe strain through pressure and temperature. For this reason, the adapter connection must be checked

regularly and the tightened if necessary. We recommend using Teflon

tape as an

additional thread seal.

• When changing the adapter, take care to not damage the diaphragm of the pressure sensing element.

• Behavior in case of under voltage If the supply voltage drops below the minimum value, the device switches off (status as if not supplied with power = switch open).
