1~DESCRIPTION.
The SEM320X is a HART 5 upwards (generic device) compatible universal temperature
transmitter with display. It accepts RTD, Thermocouple, Potentiometer or millivolt input
signals and converts them to the industry standard (4 to 20) mA transmission signal.
Alternatively, HART multidrop mode can be selected, not for ATEX applications.
It is programmed using a communication lead (USBX Config) together with our free
configuration USBSpeedlink software. Standard HART features can also be
programmed using HART communication. The SEM320X has a rotational five-digit
display for the process value and a 5-digit display for messaging, in addition to a bar
graph for % of mA output.
The apparatus is intended for use mounted in a suitable ATEX or IEC Ex approved
enclosure which provides at least IP64 protection.
Sensor types RTD, Thermocouple, Slide wire (resistance). Output two wire (4 to 20) mA
loop, with HART interface.
2~RECEIVING AND UNPACKING.

6~INSTALLATION.
6~1 MECHANICAL.
The display device is mounted using a three-pin plastic module support for fitting into a
suitable connection head. The module support is secured into the head with screws.
The orientation of the display can be adjusted as required by rotating the display in the
module support. Care must be taken to avoid over-stressing any wiring.
The display must be installed with adequate protection from moisture and corrosive
atmospheres. The device must be located so the ambient temperature does not exceed
the specified operating temperature of the device.
The SEM320X module is mounted using two or three holes, with various fixing centres
and will fit a suitable ATEX /IEC Ex approved termination head. The SEM320X must be
installed with adequate protection from moisture and corrosive atmospheres. Refer to
"special conditions for safe use" section of this user guide for information on enclosure
IP rating.
Care must be taken to ensure the SEM320X is located such that the ambient
temperature does not exceed the specified operating temperature as specified in the
"ABSOLUTE MAXIMUM CONDITIONS" table.
Mount the SEM320X into the approved housing as shown below.

Electrical connections are made to the two-part screw terminals provided on the back of
the device. The transmitter is protected against reverse connection and over-voltage. If
no sensor (input) connection is made, the transmitter will go into either up or down
scale output current, depending on configuration setting.
TURN OFF SUPPLY BEFORE WORKING ON ANY ELECTRICAL CONNECTION.
For a wiring diagram, please refer to the rear panel of the device inside the case
housing, and this document.
Two-part connectors are used for input and output connections, allowing the
device to be easily removed if required.

RTD input wires must be equal length and type.
Sensor connections are as figure 2: to maintain BS EN61326
compliance, sensor wires must be less than 3 metres. All sensor
connections must be isolated from ground.
For RTD dual input use two wire RTDs. If required, user-offsets can be done on both
inputs to known input values.
Thermocouple inputs must use correct compensation cable.
Sensor connections are as figure 2: to maintain BS EN61326 compliance, sensor wires
must be less than 3 metres. All sensor connections must be isolated from ground.
For dual thermocouple input, both thermocouples must be of the same type.
If required, user-offsets can be done on both inputs to known input values.
(4 to 20) mA Loop connections.
Ensure all other aspects of the installation comply with the requirements of this document.
To maintain CE compliance, the (4 to 20) mA current loop must be tied to a local earth at
one point; this is normally at the power supply.
Use twisted pair or screened cables for cable lengths greater than 3 metres. Maximum
cable length 1000 metres.

7~USER CONFIGURATION.
IMPORTANT.
READ COMPLETE SECTION BEFORE ATTEMPTING CONFIGURATION.
WARNING.
For configuring or reading live data if using a grounded input or output, it is important
not to connect the programming USB lead to a mains powered computer. It is possible
to damage the instrument if connected in this way.
To avoid damage, use one of the following methods:
•Disconnect the input and output connectors before configuration, reconnect the
connectors after configuration.
•Use a laptop-type computer running from its battery power supply, not connected
to a mains supply. This is recommended for reading live device data or offsetting a
device if already installed in the field.
•Use an approved USB isolator (USBX Config) between the computer and the
device, see supplier for details.
DISPLAY: The display provides five 7-segment characters for display of value and 5
14-segment characters for messages, together with a 10-segment bar graph, % of
output signal display and five icons. The display can operate in an ambient temperature
range of (-20 to 85) °C, but at temperatures lower than -5 °C (due to the slower LCD
speed) scrolled messaging is not practical. The display’s high contrast offers clear
readouts at low as well as high ambient light and direct sunlight.

7~1 USBSpeedLink USER CONFIGURATION.
A USBX configuration module is required for connecting the device to the PC. Refer to
your supplier for details.
The device can be configured whilst connected and powered but a portable battery
powered computer must be used to avoid the effects of ground loops if the (4 to20) mA
loop is grounded. This may cause damage to the display device.
