Protecting access via a password

Different passwords are available to protect write access to the parameters of the device.
Protect write access to the parameters of the device via the local display, web browser or
operating tool (e.g. FieldCare, DeviceCare). Access authorization is clearly regulated throughthe use of a user-specific access code.
User-specific access code
Write access to the parameters of the device via the local display, web browser or operating
tool (e.g. FieldCare, DeviceCare) can be protected using the editable, user-specific access code.
General notes on the use of passwords• During commissioning, change the access code that was used when the device was deliveredfrom the factory• When defining and managing the access code, comply with the general rules for thegeneration of a secure password• The user is responsible for managing the access code and for using the code with due care
3.7.2

Access via web server

Due to the integrated web server, the device can be operated and configured via a web
browser and PROFINET with Ethernet-APL. In addition to the measured values, device status
information is also displayed, allowing users to monitor the status of the device. Furthermore
the device data can be managed and the network parameters can be configured.
Access to the network is required for the PROFINET with Ethernet-APL connection.
Supported functions
Data exchange between the operating unit (such as a notebook for example) and themeasuring device:• Export parameter settings (PDF file, create documentation of the measuring point
configuration)• Export the Heartbeat Technology verification report (PDF file, only available with the"Heartbeat Verification" application package)• Download driver (GSDML) for system integration
The web server is enabled when the device is delivered. The web server can be disabled via the

Mounting requirements

5.1.1

General instructions• Do not clean or touch the membrane with hard and/or pointed objects.
• Do not remove the protection on the membrane until just before installation.
Always firmly tighten the housing cover and the cable entries.
1.

Counter-tighten the cable entries.

2.

Tighten the coupling nut.

5.1.2

Installation instructions• The standard devices (without diaphragm seals) are mounted according to the sameguidelines as pressure gauges (DIN EN837-2)• To ensure optimal readability of the local display, adjust the housing and local display• Endress+Hauser offers a mounting bracket to mount the device on pipes or walls• Use flushing rings for flanges, flange seals and pancake seals if buildup or clogging can be
expected at the membrane• The flushing ring is clamped between the process connection and the flange, flange sealor pancake seal
• Material buildup in front of the membrane is flushed away, and the pressure chamber isvented, via the two lateral flushing holes• When measuring in media containing solids (e.g. dirty liquids), installing separators anddrain valves is useful for capturing and removing sediment• Using a valve manifold allows for easy commissioning, installation and maintenancewithout interrupting the process• When mounting the device, establishing the electrical connection and during operation:
prevent the penetration of moisture into the housing• Point the cable and plug downwards as much as possible to prevent moisture from entering(e.g. rainwater or condensation)

Mounting

Installation instructions for thread• Device with G 1 ½" thread:Place the flat seal on the sealing surface of the process connection
Avoid additional strain on the membrane: do not seal the thread with hemp or similarmaterials• Device with NPT thread:• Wrap Teflon tape around the thread to seal it• Tighten the device at the hexagon bolt only; do not turn it by the housing• When screwing in, do not overtighten the thread; tighten the NPT thread to the required
depth according to the standard• For the following process connections, a tightening torque of max. 40 Nm (29.50 lbf ft) is
specified:• Thread ISO228 G ½" with flush membrane• Thread DIN13 M20 x 1.5 with flush membrane• NPT 3/4" with flush membrane
5.1.4

Installation instructions for devices with diaphragm seals

NOTICE
Improper handling!
Damage to the device!
‣ The diaphragm seal and pressure transmitter form a closed, calibrated system which has
been filled with diaphragm seal fill fluid. Never open any of the holes for fill fluid.
‣ Ensure strain relief to prevent the capillary from bending (bending radius ≥100 mm (3.94 in)).
‣ Do not use capillaries as a carrying aid for the diaphragm seals.
‣ Observe the application limits of the fill fluid.
General information
In the case of devices with diaphragm seals and capillaries, the zero point shift caused by thehydrostatic pressure of the filling liquid column in the capillaries must be taken into accountwhen selecting the measuring cell. If a measuring cell with a small measuring range isselected, a position adjustment can cause the measuring cell to go over range (position
adjustment due to zero point offset, caused by the orientation of the fill fluid liquid column).
Perform zero adjustment if necessary.
For devices with a capillary, use a suitable bracket (mounting bracket) for mounting.
When mounting, sufficient strain relief must be provided for the capillary to prevent thecapillary from bending (capillary bending radius ≥ 100 mm (3.94 in)).
Mount the capillary so that it is vibration-free (in order to avoid additional pressure
fluctuations).
Do not mount capillaries in the vicinity of heating or cooling lines and protect them against
direct sunlight.
More detailed installation instructions are provided in the Applicator "Sizing Diaphragm Seal".

Orientation

NOTICE
Damage to the device!
If a heated device is cooled during a cleaning process (e.g. by cold water), a vacuum develops
for a short time. As a result of this, moisture can enter the measuring cell via the pressurecompensation element (1).
‣ Mount the device as follows.

1
A0038723• Keep the pressure compensation element (1) free from contamination• A position-dependent zero point shift (when the vessel is empty the measured value does
not display zero) can be corrected• Diaphragm seals also shift the zero point, depending on the installation position• The use of shutoff devices and/or water pocket pipes is recommended for mounting• The orientation depends on the measuring application

5.2

Mounting the device

5.2.1

Pressure measurement in gases

Mount the device with the shutoff device above the tapping point so that any condensate canflow into the process.
5.2.2

Pressure measurement in steam

Observe the maximum permitted ambient temperature of the transmitter!
Mounting:• Ideally, mount the device with the O-shaped siphon below the tapping point
The device may also be mounted above the tapping point• Fill the siphon with liquid before commissioning

Electrical connection

Advantages of using siphons:• Protects the measuring device from hot, pressurized media due to the formation andcollection of condensate• Attenuation of water hammer• The defined water column only causes minimal (negligible) measured errors and minimal(negligible) thermal effects on the device
For technical data (e.g. materials, dimensions or order numbers), see the accessory
document SD01553P.
5.2.3

Pressure measurement in liquids

Mount the device with the shutoff device below or at the same level as the tapping point.
5.2.4

Level measurement• Always mount the device below the lowest measuring point• Do not install the device at the following positions:• In the filling curtain• In the tank outlet• In the suction area of a pump
• At a point in the tank which could be affected by pressure pulses from the agitator• Mount the device downstream from a shutoff device: the calibration and function check can
be carried out more easily
5.2.5

Closing the housing covers

NOTICE
Thread and housing cover damaged from dirt and fouling!
‣ Remove dirt (e.g. sand.) on the thread of the cover and housing.
‣ If you continue to encounter resistance when closing the cover, check the thread again forfouling.
Housing thread
The threads of the electronics and connection compartment can be coated with an antifriction coating.
