Mechanical Detail
Maintenance
The appropriate regulations concerning maintenance, repair and testing must be observed. In particular, all parts on which explosion protection depends must be checked during maintenance. The transmitter must never be configured in the hazardous area, the device must be removed and taken to a non hazardous area for configuration.
The enclosure used to house the SEM210X must be cleaned regularly to prevent build up of excessive dust layers. The SEM210X apparatus contains no user serviceable adjustable, replaceable parts. No attempt should be made to repair a SEM210X
device, all units must be returned to the manufacturer for repair or replacement. Attempted service or replacement of parts may invalidate
the explosive protection features of the SEM210X.
The SEM210X is mounted using two holes, on standard 33 mm fixing centres and will fit a DIN standard termination head. The SEM210X 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 SEM210X is located to ensure the ambient
temperature does not exceed the specified operating temperature as specified in the "TEMPERATURE CLASS" table. A 6.3 mm hole is provided in the centre of the transmitter for sensor wires. The sensor wires may also be fed on the outside of the transmitter.
Electrical Detail
REFER TO CONDITIONS FOR SAFE USE
Special conditions for safe use
1. a) For gas applications, the SEM210X temperature transmitters must be mounted in an ATEX/IECEx approved enclosure rated for IP54 and located in an area where the enclosure will not be subject to impact or friction
b) For dust applications, the SEM210X temperature transmitters must be mounted in a suitably ATEX or IECEx certified enclosure
appropriate for the zone of end use.
2. The equipment shall only be configured by means of the USB connection outside the hazardous area.
3. If 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 non­intrinsically safe circuit.
5. The ambient temperature range of the enclosure will limit the permitted ambient range of the overall equipment. Refer to enclosure certification.
Sensor wires must be isolated from earth breakdown voltage 500 V dc

Installation
For SEM210X specification please refer to product data sheet. Installation is normally performed in the following order. If the SEM210X has been purchased as part of a probe assembly ,steps (1 to 3 ) will have been completed. The user may wish to reconfigure the transmitter range, in this instance the SEM210X range can be changed on a completed probe assembly by following step 1.
1. Configuration
2. Mount Transmitter into head
3. Wire Sensor
4. Install Assembly
5. Wire (4 to 20) mA Loop

1. Configuration – Only to be performed in the safe area
Once software is i nstalled remove protection cover from device port , plug in configurator plugs in to device ports and connect PC to configurator using USB cable.
In USBSpeedLink software, select Model type from “Field Product – In Head TX” menu. For further information on configuration please open the help menu on the product configuration screen. On completion of configuration remove USB cable and replace protective cover over socket.
EX
The main configuration is performed using the USB interface. The following parameters may be configured using the powerful USBSpeed link software tool, which also provide operator diagnostics. The following functions apply :-
SENSOR
Sensor type mV, Dual mV, ohms, slide wire, thermocouple, dual thermocouple, RTD, dual RTD (2 wire). Sensor wire (ohms and rtd ranges only) 2, 3, or 4 wire. Thermocouple type Download from USBspeedlink expanding library, common type K,J,T,E,R,S,N,B,U,G,C,D. Thermocouple CJ Fixed or Auto. RTD type Download from USBspeedlink expanding library, common type PT100, PT1000, PT500, Ni, CU, KTY series. Sensor(s) Fail Value on sensor A, (sensor B) fail. Sensor Pre-set Override sensor signal with pre-set value, primary function diagnostics.
PROCESS

2. Mount Transmitter into Head
The SEM210X is mounted using two holes, on standard 33 mm fixing centres and will fit a DIN standard termination head. The SEM210X 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. A centre hole is provided in the SEM210X case, this allows for sensor wire to enter wiring section through the SEM210X body. Observe the "special conditions for safe use " instruction.
3. Sensor Connection
4. Install assembly
Care must be taken to ensure the SEM210X is located to ensure the ambient temperature does not exceed the specified operating temperature (-40 to 85) °C
5. Wire (4 to 20) mA Loop
