(parameters Pb, Ti and Td are visible).
Note: When the Autotuning and the soft start, or the delay at
the start up, have been programmed, the instrument
performs first the soft start (with the parameters it has
in memory) and then performs the Autotuning.

[15] tr1 - Out1 cycle time

[16] o2F - Out2 function
Range:

no = Not used;
HAL = Absolute high alarm;
LAL = Absolute low alarm;
b.AL = Band alarm (simmetric to the set point);
dHA = Deviation high alarm;
dLA = Deviation low alarm.
- When o1F = on.H or on.C:
no = Not used;
HAL = Absolute high alarm;
LAL = Absolute low alarm;
b.AL = Band alarm (simmetric to the set point);
dHA = Deviation high alarm ;
dLA = Deviation low alarm;
SP.C = SP2 - ON /OFF control with cooling action ;
SP.H = SP2 - ON /OFF control with heating action ;
nr = ON/OFF Neutral Zone [o2F will make the opposite ac-
tion to the one programmed on o1F, while the hysteresis
(parameter d1) becomes the neutral zone].
Note: The Neutral Zone functioning is used to control the plants
with an element that causes a positive increase (ex.
Heating, Humidifying etc.) and an element that causes a
negative increase (ex. Cooling, Dehumidifying etc.).
The control works on the programmed outputs depending
on the measure, on the active Set point “SP”, and on the
programmed hysteresis “d1”.
The controller works in the following way: it switches OFF the
outputs when the process value reaches the Set Point and
activates the heating output when the process value is lower
than [SP - d1], or it switches on the cooling output when the
process value is higher than [SP + d1].
Accordingly, the element that causes the positive increase
must be connected to the output programmed as heating,
while the element of negative increase must be connected to
the output programmed as cooling.

[20] AL.t - Inhibition time of the alarm at start up
or after a Set Point change
Range: 0 = OFF (any hidding)/0.01 ÷ 9.59 hh.mm.
Note: When the measure reaches the alarm threshold, the
instrument disables the hidding of the alarm.
[21] Pct - Compressor protection time
The protection prevents the output cycling and therefore re-
duces relay wear by waiting for the time setting to elapse be-
fore allowing a subsequent switching of the output. In other
words, it defines the minimum time that will pass between the
switch off of a cooling output and its following reactivation.
Available:
When at least one output is programmed as
cooling output.
Range: 0 (OFF)/0.01 ÷ 9.59 hh.mm.
Note: This parameter has effect to ALL the cooling outputs.
[22] SSt - Soft start time
Range: 0 (OFF)/0.01 ÷ 9.59 hh.mm.
Note: When the control type is ON/OFF, the time of the soft
start becomes an output time delay, the power is forced
to 0 and the parameter SSP is hidden.
[23] SSP - Power during Soft Start
Available: When Sst is different from 0.
Range: 0 ÷ 100%.
Note: If programmed = 0, also the alarms and/or the second
control output remains = 0 and the instrument displays
od for the programmed time.
[24] ub.F -

key function
Range:
no = No function;
Tun = It activates the manual tuning;
Sb = Stand-by mode;
Sb.o = Stand-By mode with display off.
[25] PP - Parameters protection Password
Range: 1 ÷ 999.
[26] Lo - Time for the Key lock automatic enable
This parameter allows to set the time that the instrument will
wait before to automatically enable the key lock. The time
count will re-start after a key pressure.
Range: 0 (lock disabled)/1 ÷ 30 minutes.
6. ERROR MESSAGES
6.1 Out of range signals
The display shows the OVER-RANGE and UNDERRANGE
conditions with the following indications:
Over range
Under range
The sensor break will be signaled as follows:
Sensor break
Note: When an over-range or an under-range is detected, the
alarms operate as in presence of the maximum or the
minimum measurable value respectively.
To check the out of span Error condition, proceed as follows:
1. Check the input signal source and the connecting line;
2. Make sure that the input signal is in accordance with the
instrument configuration. Otherwise, modify the input
configuration (see section 4).
3. If no error is detected, send the instrument to your sup-
plier to be checked.
6.2 List of possible errors
AtE - Auto-tune not finished within 12 hours.
EPr - Possible problem of the instrument memory.
The messages disappear automatically.
When the error continues, send the instrument to your supplier.
