+ 8 = ALARM AKNOWLEDGED: The alarm is active in alarm 
conditions and can be deactivated through key “T” if properly 
programmed (“USrb”=ASi), also if alarm conditions still exist. 

AL1

 – ALARM AL1 THRESHOLD : Alarm AL1 threshold for low and 

high alarms. 

AL1L

 – LOW ALARM AL1 : Alarm AL1 low threshold when the alarm 

is a band type or minimum set of AL1 alarm threshold when the 
alarm is low or high type. 

AL1H

 – HIGH ALARM AL1: Alarm AL1 high threshold when the 

alarm is a band type or maximum set of AL1 alarm threshold when 
the alarm is low or high type. 

HAL1 - 

ALARM AL1 HYSTERESIS: Asymmetrical semi-band 

relative to alarm AL1 threshold which defines the deactivation value 
of alarm AL1. 

AL1d

 – ACTIVATION DELAY OF ALARM AL1: This permits 

definition of  alarm delay activation AL1 when the delay function on 
par. “Ab1” is activated. 

AL1i

 – ALARM AL1 ACTIVATION IN CASE OF MEASUREMENT 

ERROR: This permits a definition of measurement error conditions, 
i.e whether the alarm has to be active ("yES") or not ("no"). 
 

GROUP “LbA” (PARAMETERS RELATIVE TO THE LOOP 
BREAK ALARM): this contains the parameters relative to the 
Loop Break alarm (control loop interruption), which intervenes 
when, for any reason (short-circuit of a thermocouple, load 
interruption, etc) the control loop is interrupted.  
OLbA

 – OUTPUT WHERE THE LOOP BREAK ALARM IS 

ADDRESSED: This defines to which output the LOOP BREAK alarm 
has to be addressed.  

LbAt

 – TIME NECESSARY TO ACTIVATE THE LOOP BREAK 

ALARM :  Delay time to the intervention of the Loop Break alarm. 
The alarm intervenes when the output power remains at 100% for 
the time programmed on this parameter (in sec.) 
 

GROUP “ 

]

rEG” (PARAMETERS RELATIVE TO THE CONTROL): 

this contains the parameters relative to control functions. 
Cont 

– CONTROL TYPE: This permits selection of one of the 

possible control modes offered by the instrument : PID (Pid),  
ON/OFF with asymmetrical hysteresis (On.FA),  ON/OFF with 
symmetrical hysteresis (On.FS), Neutral Zone ON/OFF (nr).

 

Func –

 FUNCTIONING MODE OUTPUT 1rEG:

 

this permits one to 

decide whether the control output 1rEG has to carry out a reverse 
action, as for example a Heating process ("HEAt") or a direct action, 
as for example a Cooling process ("CooL"). 

HSEt

 –ON/OFF CONTROL HYSTERESIS: Semi-band relative to the 

Set Point which defines the activation and deactivation values of the 
control output/s in case of  ON/OFF control (On.FA, On.FS, nr). 

CPdt – 

COMPRESSOR PROTECTION DELAY TIME: The delay 

time is counted starting from the last 2rEG output switch off , when 
it’s used as Neutral zone control mode, during which the output is 
kept in off state. The output will be switched on when the 
temperature regulator requires it at this time is elapsed. The function 
in deactivated programming "CPdt" = OFF. 

Auto

 – AUTOTUNING FAST ENABLE : this parameter allows one  

to decide how Auto-tuning has to be carried out. The possible 
selections are : 
= 1 – if auto-tuning is desired automatically, each time the instrument 
is switched on, on the condition that the process value is lower (with 
“Func” =HEAt) than [SP- |SP/2|] or higher (with “Func” =CooL) than 
[SP+ |SP/2|]. 
= 2 – if auto-tuning is desired automatically, the next time the 
instrument is switched on, on the condition that the process value is 
lower (with “Func” =HEAt) than [SP- |SP/2|] or higher (with “Func” 
=CooL) than [SP+ |SP/2|], and once the tuning is finished, the par. 
“Auto” is automatically swapped to the OFF state  
= 3  - if manual auto-tuning is desired, by selecting  par. “tunE” in the 
main menu or by correctly programming key “T” as “USrb” = tunE. In 
this case the auto-tuning starts without any control on the process 
value condition. It is recommended to use this option, starting the 
auto-tuning when the process value is as far as possible from the 
Set Point because, in order to feature the Auto-tuning FAST with its 
best performances , it is preferable to respect this condition. 

= 4  - if it’s desired to activate the autotuning automatically at the end 
of programmed Soft-Start cycle. The Autotuning will start at the 
condition that the process value is lower (with “Func” =HEAt) than 
[SP- |SP/2|] or higher (with “Func” =CooL) than [SP+ |SP/2|]. 
= OFF - Autotuning disabled. 
When it’s occurring an Autotuning cycle, led AT blinks. 

SELF

 – SELF-TUNING ENABLE: Parameter used to enable (yES) 

or disable (no) the Self-tuning function. Once the function has been 
enabled, the Self-tuning has to be started by selecting item “tunE”, in 
the main menu, or through key T properly programmed (“USrb” = 
tunE).When the Self-tuning function is active, led AT is permanently 
lit, and all the PID parameters ("Pb", "Int", "dEr", ecc.) are no longer 
visualised. 

Pb

 – PROPORTIONAL BAND: Width of the band around the Set 

Point within which the proportional control is performed. 

Int

 – INTEGRAL TIME: Integral time to be programmed in the PID 

algorithm, expressed in sec.  

dEr

 – DERIVATIVE TIME: : Derivative time to be programmed in the 

PID algorithm, expressed in sec.  

FuOc 

- FUZZY OVERSHOOT CONTROL: Parameter that permits 

the elimination of the variable over-shoots at the start up of the 
process or at the changing of the Set Point. A low value of this 
parameter reduces the overshoot while a high value increase it.  
 

tcr1

 – CYCLE TIME OF OUTPUT 1rEG : Cycle time of output 1rEG 

with PID control mode, expressed in sec.. 

Prat

 – POWER RATIO 2rEG / 1rEG : Parameter where it is possible 

to program the power ratio between the element controlled by output 
2rEG (ex.Cooling) and the element controlled by output 1rEG (ex. 
Heating) in case of PID double action control. 

tcr2

 - CYCLE TIME OF OUTPUT 2rEG : Cycle time of output 2rEG 

with PID double action control mode, expressed in sec.. 

rS

 -  MANUAL RESET: Power Offset added to the power increase of 

the proportional term, in order to eliminate the error when it is not 
present the integral value. This parameter is only visualised when  
“Int” =0. 

Parameters relative to the ramps, allowing the Set Point to be 
reached in a predetermined time.  
Furthermore, once the first Set (SP1) has been reached, it is 
possible to have automatic switching to the second Set (SP2) 
after a programmable time, thus obtaining a simple thermal 
cycle (functions available for all the control types)   
SLor

 – GRADIENT OF RISE RAMP:  Gradient of rise ramp to be 

carried out when the process value is lower than the active Set 
Point, expressed in unit/minute. 
Programming the parameter = InF the ramp is not active. 

dur.t - 

DWELL TIME: Dwell time of the Set Point SP1 before the 

automatic switching to SP2 (expressed in hrs. and min.) 
Using this parameter,

 

once the first Set (SP1) has been reached, it is 

possible to have automatic switching to the second Set (SP2) after a 
programmable time, thus obtaining a simple thermal cycle. 
Programming the parameter = InF the function is not active. 

SLoF

 - GRADIENT OF FALL RAMP:  Gradient of fall ramp to be 

carried out when the process value is higher than the active Set 
Point, expressed in unit/minute. 
Programming the parameter = InF the ramp is not active. 

Parameters relative to the Soft-Start function, which allows 
limitation of control power, when the instrument is switched on, 
for a predetermined time. This function is only available for PID 
control. 
St.P

 - SOFT START POWER: If parameter “SSt” is programmed 

with a value other than OFF, this is the power given as output at the 
instrument switch on, for the time “SSt”.  
Practically speaking, the instrument works in manual condition and 
switches to automatic control at the elapsing of time “SSt”. 
If instead par. “St.P” = OFF and a value is set  on par. “SSt” at switch 
on, the power calculated by the PID controller is divided by the time 
“SSt”, in order to calculate a ramp. The output power starts from 0 
and is progressively increased, according to the calculated ramp, 
until the time “SSt” is reached or until the power overcomes the 
power calculated by the PID controller. 

SSt

 - SOFT START TIME (for PID control only): Duration time in 

hours and min. of the Soft-Start described on pa. “St.P”.  
To disable the Soft-Start function set par. “SSt” = OFF.
