1.3 Precautions for safe use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse
affects on the performance and functions of the product. №t doing so may occasionally result in
unexpected events. Do not handle the Digital Controller in ways that exceed the ratings.
• The product is designed for indoor use only. Do not use or store the product outdoors or in any of
the following places.
- Places directly subject to heat radiated from heating equipment.
- Places subject to splashing liquid or oil atmosphere.
- Places subject to direct sunlight.
- Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
- Places subject to intense temperature change.
- Places subject to icing and condensation.
- Places subject to vibration and large shocks.
• Installing two or more controllers in close proximity might lead to increased internal temperature
and this might shorten the life cycle of electronic components. It is strongly recommended to
install cooling fans or other air-conditioning devices inside the control cabinet.
• Always check the terminal names and polarity and be sure to wire properly. Do not wire the
terminals that are not used.
• To avoid inductive noise, keep the controller wiring away from power cables that carry high voltages
or large currents. Also, do not wire power lines together with or parallel to Digital Controller
wiring. Using shielded cables and using separate conduits or ducts is recommended. Attach a
surge suppressor or noise filter to peripheral devices that generate noise (in particular motors,
transformers, solenoids, magnetic coils or other equipment that have an inductance component).
When a noise filter is used at the power supply, first check the voltage or current, and attach the
noise filter as close as possible to the Digital Controller. Allow as much space as possible between
the Digital Controller and devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
• A switch or circuit breaker must be provided close to device. The switch or circuit breaker must be
within easy reach of the operator, and must be marked as a disconnecting means for the controller.
• The device must be protected by a fuse 1A (cl. 9.6.2).
• Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine,
alcohol, or any cleaners that contain these or other organic solvents. Deformation or discoloration
may occur.
• The number of non-volatile memory write operations is limited. Therefore, use EEprom write mode
when frequently overwriting data, e.g.: through communications.
• Chemicals/solvents, cleaning agents and other liquids must not be used.
• Non-respect of these instructions may reduce performances and safety of the devices and cause
danger for people and property.
1.4 Environmental policy / WEEE
Do not dispose electric tools together with household waste material.
According to European Directive 2012/19/EU 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. 2 Automatic Tune
Automatic tuning procedure allows a precise regulation without delving into the PID regulation
algorithm. Selecting Auto on par. 73 t u n .1 (for the regulation loop 1), the controller analyzes the proces
oscillations and optimizes the PID parameters.
Led TUN flashes.
If the PID parameters are not yet selected, at the device switch-on, it is automatically launched the
manual Tuning procedure described into the next paragraph.
7. 3 Manual Tune
Manual procedure allows the user greater flexibility to decide when to update
PID algorithm parameters. During the manual tuning, the device generates a step to analyze the
system inertia to be regulated and, according to the collected data, modifies PID parameters.
After selecting Manu. on par. 73 t u n .1 , the procedure can be activated as follows:
• Running Tuning by keyboard:
Press FNC until display 2 shows tunE with display 1 on dis. and then press SET: display 1 shows Enab.
Led TUN switches ON and the procedure starts.
• Running Tuning by digital input:
Select tunE on par. 231 d .i .1 . F. . At first activation of digital input (commutation on front panel) led TUN
led switches on and at second activation switches off.
To avoid an overshoot, the treshold where the controller calculates new PID parameters is determined
by this operation:
Tune threshold = Setpoint -
“Set Deviation Tune” (par. 74 s.d.t.1)
Ex.: if the sepoint is 100.0∞C and the Par.32 s.d.t.1 is 20.0∞C the threshold to calculate PID parameters
is (100.0 - 20.0) = 80.0∞C.
For a greater precision on PID parameters calculation it is suggested to start the manual tuning
procedure when the process deviates from the setpoint.
7.4 Tuning once
Set once on parameter 73 t u n .1 .
Autotuning procedure is executed only once at next device restart. If the procedure doesn’t work, will
be executed at next restart.
7. 5 Digital input functions
The ATR224 and DRR224 functions related to digital inputs, can be enabled by parameter 231 d . i .1 . F. .
• 2t.Sw .: Two threshold setpoint modification: with digital input active the device regulates on SET2,
otherwise reulates on SET1;
• ru n .: The regulation is enabled only with digital input active,
• tune: Enables/disables the Tuning if par. 73 t u n .1 is selected as manu.;
• au.ma.i.: If par. 48 a.ma.1. is selected as enab. or en.sto., with impulse command on digital input, the
device switches the related regulation loop, from automatic to manual and vice versa.
• au.ma.c.: If par. 48 a.ma.1. is selected as enab. or en.sto. the devices switches to manual the related
regulation loop, with digital input active, otherwise the regulation is automatic.
• Act. ty .: the device execute a cooling type regulation with digital input active, otherwise the
regulation is of heating type;
• M. reS.: Allows the reset of the output if manual reset is active for the alarms and for the command
outputs.

7.6 Automatic / Manual regulation for % output control
This function allows to switch from automatic functioning to manual command of the output
percentage.
With par. 48 A . m a .1 . (for regulation loop 1) it is possible to select two modes.
1 First selection (enab.) allows to enable with FNC the writing p.--- on display 1, while on display 2 is
showed autom.
Press SET to visualize manu.; it’s now possible, during the process visualization, modify through the
keys
c
and
d
the output percentage. To back to automatic, with the same procedure, select autom.
on display 2: immediately led MAN switches off and functioning backs to automatic.
2 Second selection (en.sto.) 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 switches to manual mode while
maintaining the output percentage command unchanged as generated by the PID immediately
before breakage.
Ex: on an extruder the command in percentage of the resistance (load) is maintained also in case of
input sensor failure.
7.7 LATCH ON Function
For use with input po t. and with linear input (0..10 V, 0..40 mV, 0/4..20 mA) it is possible to associate start
value of the scale (par. 4 L.L.i .1) to the minimum position of the sensor and value of the scale end (par. 5
u.L.i.1) to the maximum position of the sensor (par. 10 L t c .1 configured as stndr).
It is also possible to fix the point in which the controller will display 0 (however keeping the scale range
between L.L.i .1 and u.L.i. 1) using the
“virtual zero” option by selectin u.0.sto. on par. 10 L t c .1 . Selecting
u.0.t.on. the virtual zero must be reset at each switching on; selecting u.0.sto.the virtual zero will remain
fixed once calibrated. To use the LATCH ON function, configure the par. L t c .1 1
Then refer to the following table for the calibration procedure:

7.8 Soft-Start Function
The devices is provided with two types of softstart selectable on parameter 264 SS. tY. ( “Softstart Type” ).
1 First selection (GrA d .) enables gradient softstart. AAt starting the controller reaches setpoint basing
on the rising gradient set on parameter 266 SS.G r. (
“Softstart Gradient” ) in Unit/hour (ex. °C/h). If
parameter 269 SS . ti . (
“Softstart Time” ) is different to 0, at starting when the time selected on par.
269 is elapsed, the controller stops to follow the gradient and reaches setpoint with the maximum
power.
2 Second selection (PErc.) abilita enables output percentage softstart. On par. 268 SS. tH. it is possible to
set the threshold under which starts the softstart (
“Softstart Threshold” ). On par. 267 SS.PE. ( “Softstart
Percentage”
) an output percentage is selectable (from 0 to 100), which controller keeps until the
process exceeds the threshold set on par. 268 or until the time in minutes set on par. 269 SS . ti .
( “Softstart Time” word 2084).
If the Sof-Start function is active the automatic/manual Tuning function cannot be activated.
8 Reading and configuration through NFC
Programmable
via RFID /NFC.
№ wiring required! Scan the Qr-Code
to download the App
on Google Play Store®
The controller ATR224 and DRR224 is supported by the App MyPixsys: using an ANDROID smartphone
with NFC connection it is possible to program the device without using a dedicated equipment. The
App allows to read, set and backup all parameters which are stored into the internal memory of Pixsys
devices.
Procedure:
• Identify the position of the NFC antenna on the smartphone (usually central, behind the back cover)
or to one of the sides in case of metal chassis. The antenna is placed on the frontal panel: between
 and FNC keys for the ATR224 and between

keys for the DRR224.
• Make sure that the NFC sensor of the phone is enabled or that there are no metal materials between
the phone and the device (ex. aluminium cover or with magnetic stand)
• It is useful to enable the system sounds on the smartphone, as the notification sound confirms that
the device has correctly been detected.
The App interface is provided with four tabs: SCAN, DATA, WRITE, EXTRA.
Select the first tab
“SCAN” to read data stored into the internal memory of the device; place the
smartphone in contact with the controller frontal panel, making sure that the phone’s antenna
matched with that of the controller.
Once detected the device, the App emits a notification sounds and proceeds with the model identifi-
cation and the reading of the parameters.
The graphic interface shows the advancement and switches to the second tab
“DATA” . It is now possible
to move the smartphone away from the controller to make the required modifications more easily.
The device parameters are divided into collapsible groups and are displayed with name, current value
and reference index to the manual. Click on a row to open the setting screen of the related parameter
with the detailed view of available options (in case of multiple choice parameters) or of the minimum/
maximum/decimals limits (for numeric parameters), included the text description (as per section n. 11
of the user manual). Once selected the chosen value, the related row will be updated and underlined
into the tab
“DATA” (hold down the line to cancel modifications).

User manual - ATR224 - DRR224 - 17
To download the new configuration on your device, select the third tab “WRITE” , place again the
smartphone in contact with the controller and wait for the notification.
The devices will show a restart request, necessary to update the configuration with the new written
modifications; if it does not restart, the controller will continue to work with the previous configuration.
In addition to the classic operation of parameters reading->modification->writing, MyPixsys is
provided with additional functions which can be accessed by the tab
“EXTRA” , as save parameters /
e-mail loaded values/ restore default values.

10.1 Parameters list functioning
The controller integrates many features that make the configuration parameters list very long. To make
it more functional, the parameters list is dynamics and it changes as the user enables / disables the
functions. Practically, using a specific function that occupies a given input (or output), the parameters
referred to other functions of that resource are hidden to the user making the parameters list more
concise.
To simplify the reading/interpretation of the parameters, pressing SET it is possible to visualize a brief
description of the selected parameter.
Finally, keeping pressed FNC, it is possible to move from the mnemonic visualization of the parameter
to the numeric one, and vice versa. Ex. The first parameter can be displayed as S E n .1 (mnemonic
visualization) or as P. 0 01 (numeric visualization).
Set the product parameters so that they are suitable for the system to be controlled. If they are not
suitable, unexpected operations may occasionally cause materials damage or accidents.
