10) End of Line Monitoring (DC Units) 

 

10.1 

Standard DC End Of Line Monitoring 

  

All DC units have a blocking diode fitted in their supply input lines. An 
end of line monitoring diode or an end of line monitoring resistor can 
be  connected  across  the  +ve  and 

–ve  terminals  in  the  flameproof 

chamber.  If  an  end  of  line  resistor  is  used  it  must  have  a  minimum 
resistance value  of  3k3  ohms  and  a  minimum  wattage  of  0.5W  or a 
minimum resistance value of 500 ohms and a minimum wattage of 2W. 

 

The  resistor  must  be  connected  directly  across  the  +ve  and  -ve 
terminals as shown in the following drawing. The resistor leads should 
be kept as short as possible. See D190-06-001 for details. 

Figure 9: End of Line Resistor placement. 

 

10.2       Custom DC Multi-Stage End Of Line Monitoring 

  

An optional 12-way terminal module is available to enable up to four 
alarm stages to be activated from three DC voltage output channels. 
The three alarm stage activation inputs can be independently 
monitored. 
  
Refer to Schematic D190-06-001, Config. 6. 
Specify Product option ‘V’ when ordering. 
Spare part code for field installation: SP78-0001 

 

 

11) Maintenance, Overhaul and Repair 

 

Maintenance,  repair  and  overhaul  of  the  equipment  should  only  be 
carried  out  by  suitably  qualified  personnel  in  accordance  with  the 
current relevant standards: 
 

For ATEx/IECEx or UKEx: 

 

EN60079-19/IEC60079-19  

 

Explosive  atmospheres 

–  Equipment  repair,  overhaul  and 

reclamation 

 

EN 60079-17/IEC60079-17    
Explosive  atmospheres 

– Electrical installations inspection 

and maintenance 

 
Units must not be opened while an explosive atmosphere is present. 
 
If opening the unit during maintenance operations, a clean 
environment must be maintained and any dust layer removed prior to 
opening the unit. 
 
Potential electrostatic charging hazard 

– Clean only with a damp 

cloth.
