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.
Please inspect the packaging and instrument thoroughly for any signs of transit
damage. If the instrument has been damaged, please notify your supplier immediately.
3~SPECIFICATION.
Refer to data sheet for full specification.
Configuration
Factory default Pt100, (0 to 100) °C, upscale burnout, 0.0°C offset
4~SPECIAL CONDITIONS.
4~1 For use to comply with CE, UKCA and safety.
1 The equipment must be installed correctly, providing enviromental
protection of IP64 or greater. Steps must be taken to ensure the
maximum ambient operating range is not exceeded. In particular the
temperature probe surface temperature at the point of entry into the
equipment housing.
2 The maximum recommended sensor wire length is 10 metres. To
maintain full CE EMC requirements for industrial applications, max length
is 3 metres.
3 The device contains no serviceable parts. No attempt must be made to
repair this product. Please return faulty devices to the supplier or
manufacturer.
4 This equipment must be installed by a qualified person. All electrical
wiring must be carried out in accordance with the appropriate regulations
for the place of installation.

4~2 ATEX / UKEX SPECIAL CONDITIONS FOR SAFE USE.
1 a) For gas applications, the SEM320X temperature transmitters must be
mounted in an ATEX/IECEx approved enclosure rated for IP64 and
located in an area where the enclosure will not be subject to impact or
friction
b) For dust applications, the SEM320X temperature transmitters must be
mounted in a suitably ATEX or IECEx certified enclosure appropriate for
the zone of end use.
2 Equipment shall only be configured by means of the USBX configurator
(certificate references ATEX EMT16ATEX0024X, IECEx EMT16.0013X &
CML21UKEX2276X) Connection outside the hazardous area. However, it
can it be config by HART in hazardous area via HART communication.
3 The equipment is mounted in an enclosure with separate IS circuits,
appropriate segregation shall be provided in accordance with
IEC 60079-11 Clause 6.2.1.
4 Only suitable for connection to Thermocouple(s), RTD temperature
sensor(s) or slide wire resistance devices or a simple apparatus. They
shall conform to the requirements for simple apparatus as defined in IEC
60079-11 clause 5.7 and shall meet the dielectric withstanding
requirements of IEC 60079-11 clause 6.3.13.
The insulation must be capable of withstanding an r.m.s a.c. test voltage
of 2U + 1000V, with a minimum of 1500V r.m.s., where U is the sum of
the voltages of the intrinsically safe and the non-intrinsically safe circuit.
5 The ambient temperature range of the enclosure will limit the permitted
ambient range of the overall equipment. Refer to enclosure certification.

~ATEX / UKEX INSTRUCTIONS.
User instruction for SEM320X electrical apparatus when used in a
hazardous area. Important: Read and understand this section before any
installation.
For safe installation of the SEM320X in hazardous areas the following instructions must
be observed. The device must be installed by competent personnel, who are familiar
with national and international laws, directives and standards that apply to their region.
For installation in European Economic Area (EEA) users in member countries must
follow requirements for electrical equipment for use in potentially explosive
atmospheres, e.g. EN60079-11 & EN IEC60079-0. This instruction sheet describes
installation, which conforms with BS EN60079-14 & BS EN60079-17. Important -
Attention must be paid to the section titled, ATEX / UKEX SPECIAL CONDITIONS FOR
SAFE USE. Failure to comply to this requirement will result in an unsafe system. The
SEM320X has been issued with a certificate, confirming compliance with European
ATEX directive 2014/34/EU, and SI2016 No.1107 for the following specification:
