P19:  

Secret code 

FACTORY DEFAULT: 0000 

Settings can be protected by a 4 digit number (secret code) (other than 0000) entered in this parameter.  If the secret code is active the PROG 
symbol is lit and the value of the parameters can only be viewed. 

To be able to do any programming or to modify the secret code or to remove protection (modify the secret code to 0000) the secret code, already 
entered, needs to be known.  The procedure is the following: Go to P19 press 

E

 to select parameter address.  Then go to parameter value, 

enter the secret code.  Press 

E

 to go to the address and 

E

 again to return to value.  Enter the new secret code or 0000. 

If there is no secret code or it is not active the PROG symbol is blinking
