4.4 PARAMETER SETTING
A
The parameter setting procedure
has a timeout. If no keys are
pressed for, at least, 30 seconds,
the controller switches back, auto-
matically, to the operator mode.
After having selected the parame-
ter 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 present-
ed on the display.
