“Inc” and “Dec” 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.
Automatic/Manual adjustment selection
Active only when PV display visualises the process
variable (button pressed for at least 5 sec.)
Function indicators
Indicates modes of operation
L1 MAN/AUTO = OFF (automatic control)
ON (manual control)
L2 PRE-HEATING = ON (running)
L3 SELFTUNING = ON (enabled Self)
OFF (disabled Self)
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)
SV display: Indication of setpoint
Indication of output states
OUT 1 (AL1); OUT 2 (OPEN); OUT 3 (CLOSED)
