HOW TO MODIFY THE WORKING PARAMETERS
The microprocessor of the INFRARED instruments allows you to configure the functions of your controller
according to the application requirements. To simplify this operation, we have divided the Working
Parameters into two main groups:
• frequently used parameters (indicated as 'F' parameters in the tables below);
• configuration parameters ('C'),  protected by a code or password to prevent unauthorised access to the
data.
All parameters can be modified via keypad (except IR32M, with no keys) as well as via remote control unit or
serial line. In order to modify the parameters via front panel keypad, observe the following instructions:
Gaining access
To gain access to the 'F' parameters:
• press the 
 
 for more than 5 seconds (in case of alarm condition, silence the buzzer first);
• the display shows the code of the first modifiable parameter  (/C);
To gain access to the 'C' parameters:
• press the  
  and    
  buttons simultaneously for more than 5 seconds;
• the display shows 00;
• press either the   or     button until '22' (the password) appears;
• confirm pressing   ;
• the display shows the code of the first modifiable parameter, that is '/C'.
How to modify the parameters
Modifying parameters: after having displayed the first parameter, either 'C' or 'F', follow these instructions:
• press  either    or     until you reach the parameter whose value needs to be changed;
• press  
 
 to display its current value;
• increase of decrease its value using the    or    key until you reach the requested value;
• press  
 
 to memorize temporarily the new value and display the code of the parameter again;
• press again  either    or     to go to the next parameter you want to change;
then repeat the operations as indicated above, starting from "press   .."
How to exit the procedure
How to memorize the new set values
• Press 
 
 to memorize the new values and exit the procedure.
Important: it is necessary to press  
 
 to memorize the new values. In case of power failure before  
has been pressed, all modifications will be lost. Whenever you modify the value of a parameter, we strongly
recommend writing it down in the dedicated column situated on page 46 of this guide (see column 'New value').
How to exit the procedure without memorizing the modified data
• do not press any key for at least 60 seconds (TIME OUT). The instrument will return to its normal 
functioning mode.
