CAUTION

!

►

Switch off power supply before installing or connecting the device. Failure to observe this may
result in destruction of parts of the electronics.

►

When installing Ex-approved devices in a hazardous area please take special note of the
instructions and connection schematics in the respective Ex documentation added to these
Operating Instructions. Your supplier is available for assistance if required.

►

Do not occupy the display connection. An incorrect connection can destroy the electronics.

A Phillips head screwdriver is required to wire the head transmitter with screw terminals. A flat­bladed screwdriver must be used for the version with spring terminals and for the DIN rail
transmitter.

NOTICE

Do not overtighten the screw terminals, as this could damage the transmitter.

►

Maximum torque = 1 Nm (¾ pound-feet).

For wiring a mounted head transmitter, proceed as follows:

1. Open the cable gland and the housing cover on the terminal head or the field housing.

2. Feed the cables through the opening in the cable gland.

3.

Connect the cables as shown in (® ä 15). If the head transmitter is fitted with spring
terminals, pay particular attention to the information in the "Connecting to spring terminals"

section" (® ä 17).

4. Retighten the cable gland and close the housing cover.

In order to avoid connection errors always take note of the hints given in the section "connection
check"!

To operate the device via the HART® protocol (terminals 1 and 2), a minimum load of 250 W is
required in the signal circuit.

►

ESD - electrostatic discharge. Protect the terminals from electrostatic discharge. Failure to

observe this may result in destruction or malfunction of parts of the electronics.

5.2 Connecting the sensor cables

Terminal assignment of the sensor terminals(® å 7, ä 15).

NOTICE

When connecting 2 sensors ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell). The
resulting equalizing currents distort the measurements considerably.

►

The sensors must remain galvanically isolated from one another by connecting each sensor
separately to a transmitter. The transmitter provides sufficient galvanic isolation (> 2 kV AC)
between the input and output.

The following connection combinations are possible when both sensor inputs are assigned:

A0017841

• The terminals for connecting the signal cable (1+ and 2-) are protected against reverse
polarity.
Conductor cross-section:

•
– Max. 2.5 mm2 for screw terminals
– max. 1.5 mm2 for spring terminals. Min. stripping length of wire 10 mm (0.39 in).

5.4 Shielding and grounding

Optimum electromagnetic compatibility (EMC) can only be guaranteed if the system components
and, in particular, the lines are shielded and the shield forms as complete a cover as possible. A
shield coverage of 90% is ideal.

• To ensure an optimum EMC protective effect when communicating with HART®, connect the
shield as often as possible to the reference ground.

• For reasons of explosion protection, you should refrain from grounding however.

To comply with both requirements, three different types of shielding are possible when
communicating with HART®:

• Shielding at both ends

• Shielding at one end on the feed side with capacitance termination at the field device

• Shielding at one end on the feed side

Experience shows that the best results with regard to EMC are achieved in most cases in
installations with one-sided shielding on the feed side (without capacitance termination at the
field device). Appropriate measures with regard to input wiring must be taken to allow
unrestricted operation when EMC interference is present. These measures have been taken into
account for this device. Operation in the event of disturbance variables as per NAMUR NE21 is

18 Endress+Hauser

thus guaranteed. Where applicable, national installation regulations and guidelines must be
observed during the installation! Where there are large differences in potential between the
individual grounding points, only one point of the shielding is connected directly with the
reference ground. In systems without potential equalization, therefore, cable shielding of fieldbus
systems should only be grounded on one side, for example at the supply unit or at safety barriers.

Shielding and grounding the signal cable at one end with HART® communication

Grounding point for HART® communication cable shield

NOTICE

If the shielding of the cable is grounded at more than one point in systems without
potential matching, power supply frequency equalizing currents can occur that damage
the signal cable or have a serious effect on signal transmission.

►

In such cases the shielding of the signal cable is to be grounded on only one side, i.e. it must
not be connected to the ground terminal of the housing (terminal head, field housing). The
shield that is not connected should be insulated!

The DIN rail transmitter version does not have an interface to the LC display TID10 and
therefore does not have a local display either.

Two LEDs on the front indicate the device status in accordance with NAMUR NE44.

Type Function and characteristic

Status LED (red) When the device is operating without errors, the device status is displayed. This

function can no longer be guaranteed in the event of an error.

LED off: without diagnostic message

•

• LED is lit: diagnostic display, category F

• LED flashing: diagnostic display of categories C, S or M

Power LED (green) 'ON' When the device is operating without errors, the operating status is displayed.

This function can no longer be guaranteed in the event of an error.

• LED off: Power failure or insufficient supply voltage

• LED is lit: Supply voltage is OK (either via CDI or via supply voltage,
terminals 1+, 2-)

6.3.2 Local operation

You can make hardware settings for the fieldbus interface using miniature switches (DIP
switches) on the rear of the optional display .

The user has the option of ordering the display with the head transmitter, or as an accessory
for subsequent mounting. (® ä 30)

Hardware settings via DIP switches

Procedure for setting the DIP switch:

1. Open the cover of the terminal head or field housing.

2. Remove the attached display from the head transmitter.

3. Configure the DIP switch on the rear of the display accordingly. In general: switch to ON =
function enabled, switch to OFF = function disabled.

4. Fit the display onto the head transmitter in the correct position. The head transmitter accepts
the settings within one second.

5. Secure the cover back onto the terminal head or field housing.

Switching write protection on/off

Write protection is switched on and off via a DIP switch on the rear of the optional attachable
display. When write protection is active, parameters cannot be modified. A key symbol on the
display indicates that the write protection is on. Write protection prevents any write access to the

24 Endress+Hauser

parameters. The write protection remains active even when the display is removed. To deactivate
the write protection, the device must be restarted with the display attached and the DIP switch
deactivated (WRITE LOCK = OFF).

Before commissioning the measuring point make sure that all final checks have been carried out:

•

Checklist “Post-installation check”, (® ä 14)

•

Checklist “Post-connection check”, (® ä 19)

Function check

8.2 Switching on the transmitter

Once the final checks have been successfully completed, it is time to switch on the supply
voltage. The transmitter performs a number of internal test functions after power-up. As this
procedure progresses, the following sequence of messages appears on the display:

Step Display

1 "Display" text and firmware version of the display

2 Firm logo

3 Device name with firmware and hardware versions

4 Information on the sensor configuration (sensor element and type of connection)

5 Set measuring range

6a Current measured value or

6b Current status message

If the switch-on procedure is not successful, the relevant diagnostics event, depending on the cause, is
displayed. A detailed list of diagnostic events and the corresponding troubleshooting instructions can be

found in the "Diagnostics and troubleshooting" section (® ä 33).

The device is operational after approx. 8 seconds, and the plug-in display after approx. 12 seconds
in normal operating mode! Normal measuring mode commences as soon as the switch-on
procedure is completed. Measured values and status values appear on the display.

8.3

If the device is locked and the parameter settings cannot be changed, it must first be enabled via
the hardware lock. The device is locked using the hardware if the keyhole symbol appears in the
header of the measured value display. To unlock the device, switch the write protection switch

on the back of the display to the "OFF" position (® ä 24).
