9)  End of Line Monitoring (DC Units) 

 
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 D190-06-201 
for details.

10) Interchangeable & Spare Parts  

 

 

 
The beacon lens is interchangeable, contact European Safety 
Systems  Ltd  for  a  replacement  lens  available  in  various 
colours. 
 
The  guard  is  an  integral  part  of  the  protection  and  must  be 
reassembled exactly the same way as it was disassembled.  

 

To change the lens, unscrew the M5 socket head screws and 
remove the M5 screws, M5 spring & flat washers.  
 

 

Figure 11: Removal of Lens. 

 

Remove the guard and replace the old lens with the new lens.  

 

Figure 12: Changing of Lens 

 

Fit the guard back on to the lens and casting, align the holes 
of the guard, lens and casting. To reattach the lens, the fixings 
MUST be in the order shown in figure 13.

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: 
 

EN60079-19/IEC60079-19  

 

Explosive atmospheres 

 Equipment repair, overhaul and 

reclamation 
 
EN 60079-17/IEC60079-17  

 

Explosive atmospheres 

 Electrical installations inspection 

and maintenance 
 

Flameproof  threaded  joints  and  cemented  joints  are  not 
permitted to be repaired. 
 
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. 

Warning 

 

Hot surfaces. External surfaces 

and internal components may be hot after 
operation, take care when handling the 
equipment.
