Introduction
Thank you for choosing a Pixsys controller.
With ATR243 model Pixsys integrates in a single device all options for sensor reading and
actuators command, beside extended supply range 24…230 Vac/Vdc. With 18 selectable
sensors and outputs configurable as relay, SSR command, 4…20 mA and 0…10 Volt the
user or retailer can reduce stock needs.
The series includes also a model with serial communication RS485 Modbus RTU and with
a loading control function via current transformer. The possibility to repeat parametriza-
tion is simplified by the Memory Cards with internal battery that do not require power
supply for the controller.
1 Safety guide lines
Read carefully the safety guidelines and programming instructions contained in this
manual before using/connecting the device.
Disconnect power supply before proceeding to hardware settings or electrical wirings.
Only qualified personnel should be allowed to use the device and/or service it and in
accordance to technical data and environmental conditions listed in this manual.
Do not dispose electric tools together with household waste material. In observance
European Directive 2002/96/EC on waste electrical and electronic equipment and its
implementation in accordance with national law, electric tools that have reached the end
of their life must be collected separately and returned to an environmentally compatible
recycling facility.

7 Controller Functions
7.1 Modifying Main Setpoint and Alarm Setpoint Values
The setpoint value can be changed by keyboard as follows:
Press Display Do
1or Value on display 2 changes. Increases or decreases the
main setpoint.
2SET
Visualize alarm setpoint
on display 1 value being
inserted.
3or Value on display 2 changes. Increases or decreases the
alarm setpoint value.
7. 2 Auto-Tuning
Tuning procedure calculates the controller parameters and can be manual or automatic
according to selection on parameter 57 (tunE).
7. 3 Manual Tuning
Manual procedure allows the user greater flexibility to decide when to update P.I.D.
algorithm work parameters. The procedure can be activated in two ways.
• Running Tuning by keyboard:
Press
SET key until display 1 shows the writing tunE with display 2 showing off
, press
, display 2 shows on.
TUN led switches on and the procedure begins.
• Running Tuning by digital input:
Select
tune on parameter 61 d G t.i . At first activation of digital input (commutation on
front panel) TUN led switches on and at second activation switches off.

ATR243 - User manual - 17
7.4 Automatic Tuning
Automatic tuning activates when the controller is switched on or when the setpoint is
modified to a value over 35%.
To avoid an overshoot, the treshold where the controller calculates new P.I.D. parameters
is determined by the setpoint value minus the “Set Deviation Tune” (see parameter 58
S.D. tu .).
To exit Tuning and keep P.I.D. values unchanged, press SET
key until display 1 shows the
writing
tune
and display 2 shows on. Press , display 2 shows off . TUN led switches off
and procedure finishes.
7. 5 Soft-Start
To reach the setpoint the controller can follow a gradient expressed in units (example:
Degree/Hours).
Enter the gradient on parameter 62 G rAd . with chosen Units/Hours; only on subsequent
activation the controller uses Soft-Start function.
If parameter 59 op.mo.
is set on co n t. and parameter 63 m a . ti . is different from 0, after
switch-on and elapsing of the time set on parameter 63, setpoint does not follow the
gradient anymore, but it reaches final setpoint with maximum power.
Autotuning does not work when only the par. GrAd . is different from 0. If parameter 63
m a . ti . is different from 0 and parameter 57 tune is set on Auto the autotuning starts
when Soft-Start time is finished, while if parameter 57 tune is set on Man. the autotuning
can be started only when Soft-Start finishes.
7.6 Automatic / Manual Regulation for % Output Control
This function allows to select automatic functioning or manual command of the output
percentage.
With parameter 60 Au.ma. the operator can select two methods:
1 First selection (en.)
Pressing
SET key display 1 shows p.---
, while display 2 shows Auto.
Pressing key display shows Man.; it is now possible to change the output percentage
using and . To return to automatic mode, using the same procedure, select
Auto on display 2: led MAN switches off and functioning returns to automatic mode.
2 Second selection (EN.ST,)
enables the same functioning, but with two important variants:
• If there is a temporary power failure or after switch-off, the manual functioning as well
as the previous output percentage value will be maintained at restarting.
• If the sensor breaks during automatic functioning, the controller moves to manual
mode while maintaining the output percentage command unchanged as generated
by the P.I.D. immediately before breakage.

First selection (P r. cy):

it reaches maximum power up to setpoint 2.
When the process reaches maximum power,
this setpoint is maintained for the time set
on parameter 63 m a . ti .
On expiry, the command output is disabled
and controller displays stop
. Cycle starts
at each activation of the controller, or via
digital input if it is enabled for this type of
functioning (see parameter 61 d Gt.i .).

Second selection (Pr. cy):
start-up is decided only on activation of the
digital input, according to the setting of
parameter 61 d G t.i . On start-up, controller
reaches setpoint 1 following gradient set in
parameter 62 Gra d .
When the process reaches this gradient, it
is maintained for the time set on parameter
63 m a . ti . On expiry, command output is
disabled and the controller displays stop
.
Variation (S.S. cY.):
Selecting S.S. cY. (Soft Start Cycle) the controller will operate as per the first selection (Pr.
cy) but with two important variations. If at starting the process is lower than SET1, the
device regulates the output power according to the percentage selected on parameter
62 GrAd.
When the process is greater than SET1 or the time selected on parameter 63 M A . ti .
is elapsed, it reaches maximum power up to SET2. When the process reaches SET2 the
controller keeps it to infinity.
If parameter 59 oP.Mo. is configured as S.S. cY. it is possible to select Hi d E on parameter 17
c. S.P.: SET1 is no longer displayed and SET2 label becomes SET.
Starting the manual tune during the regulation on SET1, TUN led switches ON only when
the regulation switches to SET2.
The autotuning (manual or automatic) works only if SET2 is being regulated. If the
autotuning is launched during regulation on SET1 it doesn’t start until the regulation
switches to SET2.

7.8 Memory Card (optional)
Parameters and setpoint values can be duplicated from one controller to another using
the Memory card.
2 modes are available:
• With the controller connected to the power supply.
Insert memory card when the controller is off.
On activation display 1 shows memo and display 2 shows --- (only if the correct
values are saved in the memory card). By pressing key display 2 shows Lo a d, then
confirm using SET key.
Controller loads the new value and restarts.

The memory card is equipped with an internal battery with an autonomy of about
1000 uses (2032 button battery, replaceable). Insert the memory card and press the
programming buttons. When writing the parameters, led turns red and on completing
the procedure it changes to green. It is possible to repeat the procedure without any
particular attention.
NB: it is not possible to transfer parameters to a device with different code: red LED is ON.

20 - ATR243 - User manual
Updating Memory Card
To update the memory card values, follow the procedure described on first mode, setting
display 2 to ---- so as not to load the parameters on controller1.
Enter configuration and change at least one parameter.
Exit configuration. Changes are stored automatically.
7.9 Latch-on function
For use with input P o t .1 (potentiometer 6 KΩ) and Po t.2 (potentiometer 150 KΩ) and with
linear input (0…10 V, 0...40 mV, 0/4…20 mA), it is possible to associate start value of the
scale (parameter 6 Lo L.i) to the minimum position of the sensor and value of end scale
(parameter 7 u P.L.i) to the maximum position of the sensor (parameter 8 La t c. configured
as Std.).
It is also possible to fix the point in which the controller will display 0 (however keeping
the scale range between Lo L.i and u P.L.i) using the “virtual zero” option by setting u .OSt.
or u.Oin.
in parameter 8 La t c.
If you set u.Oin.
the virtual zero will reset after each activation of the tool; if you set u .OSt.
the virtual zero remains fixed once tuned.
Selecting “dYn.L
” (dynamic limits) it is possible to surpass lower and upper limits if on
input there are values out of 0/4…20mA or 0…10V .
To enable the LATCH ON function select chosen configuration for parameter LA t c2.
For the calibration procedure refer to the following table:

card, but it is possible to update values.
