Function indicators
Indicates modes of operation
MAN/AUTO = OFF (automatic control)
ON (manual control)
SETPONT1/2 = OFF (IN1 = OFF - local Setpoint 1)
ON (IN1 = ON - local Setpoint 2)
SELFTUNING = ON (enabled Self)
OFF (disabled Self)
Automatic/Manual adjustment selection
Active only when PV display visualises
the process variable
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.

Indication of output states
OUT 1 (AL1); OUT 2 (Main); OUT 3 (HB); OUT 4 (HB)
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)
SV display: Indication of setpoint
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)
• Inputs
• TC Input
Available thermocouples:
J, K, R, S, T, B, E, N,
L, U, G, D, C
- Observe polarities
- For extensions, use the
correct compensating cable
