5.2.2 Connection to PROFIBUS® PA
Devices can be connected to the PROFIBUS® PA in two ways:
• Via a conventional cable gland
• Via a fieldbus connector (optional, available as an accessory)
NOTICE
The device and fieldbus cable can be damaged by electrical voltage
‣Switch off the power supply before installing or connecting the device.
‣It is recommended to ground the unit via one of the grounding screws.
‣If the shielding of the fieldbus cable is grounded at more than one point in systems without
additional potential equalization, mains frequency equalizing currents can occur that
damage the cable or shield. In such cases, the shielding of the fieldbus cable is to be
grounded on one side only, i.e. it must not be connected to the ground terminal of the
housing. The shield that is not connected should be insulated!
We recommend that the fieldbus not be looped using conventional cable glands. If you
replace even just one measuring device at a later date, the bus communication will have
to be interrupted.

• The terminals for the fieldbus connection (1+ and 2-) are independent of polarity.
• Conductor cross-section:
Max. 2.5 mm2 (14 AWG)
• Always use a shielded cable for the connection.
Fieldbus connector
As an option, a fieldbus connector can be screwed into the field housing instead of a cable
gland. Fieldbus connectors can be ordered from Endress+Hauser as an accessory (see
'Accessories' section in the Operating Instructions).
The connection technology for PROFIBUS® PA enables measuring devices to be connected to
the fieldbus via uniform mechanical connections such as T-boxes, junction boxes, etc.
This connection technology using prefabricated distribution modules and plug-in connectors
offers substantial advantages over conventional wiring:
• Field devices can be removed, replaced or added at any time during normal operation.
Communication is not interrupted.
• Installation and maintenance are significantly easier.
• Existing cable infrastructures can be used and expanded instantly, e.g. when constructing
new star distributors using 4-channel or 8-channel distribution modules.

Electrical connection RID16
16 Endress+Hauser
Supply line/T-box shielding
Always use cable glands with good EMC properties, where possible with wrapround cable
shielding (Iris spring). This requires minimum differences in potential, and possibly potential
equalization.
• The shielding of the PA cable may not be interrupted.
• The shielding connection must always be kept as short as possible.
Ideally, cable glands with Iris springs should be used to connect the shielding. The Iris spring,
which is located inside the gland, connects the shield to the T-box housing. The shielding
braid is located under the Iris spring.
When the armored thread is tightened, the Iris spring is pressed against the shielding, thereby
creating a conductive connection between the shielding and the metal housing.
A junction box or a plug-in connection must be considered part of the shielding (Faraday
shield). This applies, in particular, to remote boxes if such boxes are connected to a
PROFIBUS® PA device via a plug-in cable. In such cases, you must use a metal connector
where the cable shielding is connected to the connector housing (e.g. preterminated cables).

5.3 Ensuring the degree of protection
The devices fulfill the requirements for the IP 67 degree of protection. Compliance with the
following points is mandatory to ensure IP 67 protection is guaranteed after installation or
after service work:
• The housing seal must be clean and undamaged when inserted into the groove. The seal
should be cleaned, dried or replaced.
• The connecting cables must be of the specified outer diameter (e.g., M16 x 1.5, cable
diameter 5 to 10 mm (0.2 to 0.39 in)).
• Replace all unused cable entries with dummy plugs.
• The cable entry seal may not be removed from the cable entry.
• The housing cover and cable entry/entries must be closed securely.
• Install the device in such a way that the cable entries point downwards.
5.4 Post-connection check
After completing the device's electrical installation, carry out the following checks:

The backlit LCD display contains a bar graph (0-100) and arrows to indicate measured values
above or below the measuring range. Analog process values, digital status and failure codes
are displayed in the 7-segment area. Here up to 8 values can be displayed with an alternating
time of between 2 and 20 seconds. Plain text can be displayed in the 14-segment area (text is
limited to 16 characters and is scrolled if needed).
The indicator also displays the quality of the measured value. If the status of the displayed
value is 'good' (value equal to or above 0x80), no symbol is lit and the indicator remains in the
normal operational state. If the status of the displayed value is 'uncertain' (value between
0x40 and 0x7F), the 'Uncertain measured value status' symbol is lit. If the status is 'bad' (value
below 0x40), within the 7-segment area the display will show "BAD" and the channel number
where the bad value is published. The channel number is also displayed in the 14-segment
area.
6.1.2 Operation options
Two options are available to the operator for configuring and commissioning the device:
1. Configuration programs
Device-specific parameters are configured via the service interface (CDI). A special device
driver (DTM) for an FDT operating program (e.g., DeviceCare, FieldCare) is available for this
purpose →  20.

2. Miniature switches (DIP switches) for various hardware settings
You can make the following hardware settings for the fieldbus interface using miniature
switches (DIP switches) on the electronics module →  20:
• Setting to specify whether operation is possible via DIP switches or remotely via the DTM
• Setting for the address of the bus users whose values are to be displayed

Listener mode
The field indicator acts solely as a listener, i.e. it does not appear in the bus as an active user
with its own address and it does not increase the traffic in the bus.
The field indicator analyzes the devices active on the bus. Via their addresses, these devices
can be assigned to up to 8 channels if DTM operation is used, or 2 channels in the case of
operation with DIP switches.
Operation via the PROFIBUS protocol is not possible given the sole listener function of
the indicator!

‣The device must be configured outside the hazardous area.
To configure the device using the FieldCare Device Setup software, connect the device to your
PC. To do so, you require a special interface adapter, the Commubox FXA291 (see the
"Accessories" section in the Operating Instructions).
Insert the four-pin connector of the interface cable into the corresponding socket in the
device, insert the USB connector on the PC into a free USB slot.
You will find additional information on configuration via the PC configuration software in the
Operating Instructions.
No power should be supplied via the bus if configuring the PROFIBUS PA indicator with
the DTM via the CDI interface!
To ensure a connection to the device can be established, operation must be set to
"Remote" at the DIP switches. Furthermore, write protection, which can be enabled and
disabled via the DIP switches, must be disabled so that the parameters of the field
indicator can be modified via the DTM.
The DIP switches are described in the "Hardware settings" section →  20.
6.3 Hardware settings
Hardware write protection can be switched on and off via DIP switches inside the field
indicator. If write protection is enabled, no parameters can be changed.
The current write protection status is displayed in the "Locking status" parameter.
Proceed as follows to set the DIP switch:
1. Open the housing cover
2. Configure the DIP switch as required. Switch on ON = function switched on, switch on
OFF = function switched off.
3. Close the housing cover and secure it.
