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  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.

Sensor wires must be isolated from earth breakdown voltage 500 V dc
