“Raise” and “Lower” key
Press to increment (decrement) any numerical parameter •• Increment (decrement) speed is proportional to time
key stays pressed •• The operation is not cyclic: once the maximum (minimum) value of a field is reached, the
value will not change even if the key remains pressed.
3 • DESCRIPTION OF FACEPLATE
Automatic/Manual adjustment selection
Active only when PV display visualises the process
variable
PV Display: Indication of process variable
Error Indication: LO, HI, Sbr, Err
LO= the value of process variable is < di LO_S
HI= the value of process variable is > di HI_S
Sbr= faulty sensor or input values higher than max. limits
Err= PT100 third wire opened for PT100, PTC or input
values lower than min. limits (i.e.: TC wrong connection)
Function key
Gives access to the various configuration phases ••
Confirms change of set parameters and browses next or
previous parameter (if Auto/Man key is pressed)
Function indicators
Indicates modes of operation
MAN = OFF (Automatic control)
MAN = ON (Manual control)
AUX = OFF (IN1 = OFF - local Setpoint 1)
AUX = ON (IN1 = ON – local Setpoint 2)
REM = OFF (local Setpoint)
REM = ON (remote Setpoint)
SV display: Indication of setpoint
Indication of output states
OUT 1 (Main); OUT 2 (AL 1);
OUT 3 (AL 2); OUT 4 (HB)
