HyS Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action Hysteresis for ON/OFF control action
Available only when Pb=0.
Range: from 0.1% to 10.0% of the input span.
ti Integral time Integral time Integral time Integral time Integral time
This parameter is skipped if Pb=0 (ON/OFF
action).
Range: from 00.01 to 20.00 [mm.ss]. Above
this value the display blanks and integral action
is excluded
Note: When the device is working with SMART Note Note
Note Note
algorithm, the minimum value of the integral
time will be limited by P36 parameter.
td Derivative time Derivative time Derivative time
Derivative time Derivative time
This parameter is skipped if Pb=0 (ON/OFF
action) or P44 = Pi.
Range: From 00.00 to 10.00 mm.ss.
Note Note: When device is working with SMART Note Note Note
algorithm the td value will be equal to a quarter
of Ti value.
IP Integral pre-load. Integral pre-load. Integral pre-load. Integral pre-load. Integral pre-load.
This parameter is skipped if Pb=0 (ON/OFF
action).
- For one control output, it is program-
mable from 0 to 100 % of the output
span.
- For two control outputs it is program-
mable from -100% (100 % cooling) to
100 % (100 % heating)
Cy1 Output 1 cycle time Output 1 cycle time Output 1 cycle time Output 1 cycle time Output 1 cycle time
Range: From 1 to 200 s.
Cy2 Output 2 cycle time Output 2 cycle time Output 2 cycle time Output 2 cycle time Output 2 cycle time
Available only if P7 is equal to 4.
Range: From 1 to 200 s.
rC Relative Cooling gain. Relative Cooling gain Relative Cooling gain Relative Cooling gain Relative Cooling gain
This parameter is skipped if Pb=0 (ON/OFF
action) or P7 different from 4.
Range: from 0.20 to 1.00
Note Note: When the device is working with SMART Note Note Note
algorithm and P32 is set to ON the rC value is
limited in accordance with the selected type of
cooling media:
- from 0.85 to 1.00 when P8 = AIr
- from 0.80 to 0.90 when P8 = OIL
- from 0.30 to 0.60 when P8 = H2O

o u t p u t s. o u t p u t s o u t p u t s o u t p u t s o u t p u t s
This parameter is skipped if Pb=0 (ON/OFF action)
or P7 different from 4.
Range: from -20 to 50 % of the proportional band.
A negative OLAP value shows a dead band
while a positive value shows an overlap.
rL Set point low limit Set point low limit Set point low limit Set point low limit Set point low limit
Range: from min. range value (P3) to rH.
Notes Notes: Notes
Notes Notes
1 ) When P3 has been modified, rL will be
realigned to it
2 ) if rL has been modified and the SP (or SP2)
value is lower than the new rL value, the SP
(or SP2) value will be realigned to it.
rH Set point high limit Set point high limit Set point high limit
Set point high limit Set point high limit
Range: From rL to full scale value (P4)
Notes: Notes Notes Notes Notes
1 ) When P4 has been modified, rH will be
realigned to it
2 ) if rH has been modified and the SP (or SP2)
value is higher than the new rH value, the
SP (or SP2) value will be realigned to it.

Range: from 1 to 100 digits per minutes.
Above this value the display shows "Inf"
meaning that the transfer will be done as a step
change.

OLH Output high limit Output high limit Output high limit Output high limit Output high limit
Range:
- From 0 to 100 % when device is configured
with one control output.
- From -100 to 100% when device is configured
with two control outputs.

(Soft start) (Soft start) (Soft start) (Soft start) (Soft start)
Range: from 1 to 540 min. Above this value the
display shows "InF" meaning that the limiting
action is always on
Note Note Note: The tOL can be modified but the new Note Note
value will become operative only at the next
instrument start up.
