After having selected the parameter or the code, press S and G to display or modify the value (see pag. 20) The value is entered when the next parameter is selected, by pressing the R key.

Pressing the Q key, the next group of parameters is presented on the display.

Note

[1]It is presented only if the controller has been configured with 2 alarms. Digit L of the con- figuration code is assigned to 4 or 5

[2]It is not presented if the controller has been configured with alarm n° 2 not active or of sensor break type. Digit N of the configu- ration code is assigned to 0 or 1.

[3]If password is 0000 to 4999, parameter set- ting will be available to the operator with- out entering this password number. If pass- word is 5000 to 9999, parameter setting will only be available by entering this pass- word number.
