Reminder: all work is to be carried out by approved and trained 
personnel

 

 
 
If any fault occurs in the oxycutting equipment due to an electrical problem, first check the fuses.  Before opening 
the manifold box, switch the machine off. Using the emergency stop does not mean that there is no voltage in the 
box.

(F10 to F16) switch off the 24V power to the rest of the process. (Description : FUSE 5X20 5A 250V FSF) 
 
While troubleshooting, the Air Liquide technician may ask you to check the status of the indicators inputs/outputs
