1.1 - FRONT PANEL
1 - Key P : Use to program the functioning parameters and to confirm the
programmed data and pass then to the next parameter.
2 - Key UP: Used to increase the figure on which is placed the "cursor".
(in case of parameters not numerical, "UP" key is needed to select the
available options), to change active set point, to visualize the output
control power, to open manually motorised actuators. Keeping pushed "P"
key and pushing "UP" key, the parameters run over backwards.
3 - Key LEFT : Used to shift the "cursor" (flashing) on the figure that is
desired to modify, to visualise the current measured by TAHB input, to
reset the alarm latch, to close manually motorised actuators.
4 - Led C1 : Signalize when the output C1 is on (on) o r off (off)
5 - Led C2/A4 : Signalize when the output C2/A4 is on (on) or off (off)
6 - Led HB/A3: Signalize when the output HB/A3 is on (on) or off (off)
7 - Led AT: Signalize Seltuning on (on) or Autotuning on (flashing)
8 - Led MAN: Signalize the Manual control (flashing)
9 - Display PV: Normally shows Process Value
10 - Display SV: Normally shows Set Point Value
