Maintenance

 

5-1

 Maintenance of Flame-Proof version. 

 

1.When performing maintenance on Flame-proof version, never remove the terminal box 

cover or main cover while the power is connected. 

2.

 Always turn off the power before performing any maintenance or repair work. 

 

5-2

 Periodic Inspection

 

Performing  periodic  inspection  and  maintenance  of  the  I/P  Converter  will  help  reduce  the 

incidence of faults and extend the working life of the unit.

 

 

<Supply pressure filter> 

A  metal  mesh  is  fitted  inside  the  SUPPLY  coupling.  Use  a  pair  of  tweezers  or  similar  to 

remove any sealing tape or dirt particles caught in the mesh.

 

 

<Fixed orifice assembly>

 

The fixed orifice plays an important role in supplying the air to the nozzle. If no nozzle back 

pressure is present, this may indicate a blocked orifice. 

Take off the exhaust cover, then remove the fixed orifice assembly from the pilot relay unit 

and replace with a spare assembly. (See Figure 5-1) 

If you do not have a spare fixed orifice assembly, use [phi]0.3 piano wire or similar to clean 

the blocked orifice. Then use clean air to blow off any remaining dirt. 

When  finished  cleaning,  screw  the  assembly  back  into  its  original  position.  Take  care  to 

ensure that the O-ring is positioned correctly in the body of the pilot relay unit.
