The command setpoint is read on the
second analog input AI2: on par. 55 c.pr.2
set A.in.2. The inputs reversal is possible
by setting A.in.1 on par. 55 c.pr.2.
Selecting en.tst. on par. 56 rem.s. it is
possible to switch from remote to local
setpoint pressing SET for 1 second.
The selection is stored even after the
subsequent device restarts.
In remote setpoint mode, the REM LED
flashes; it is off when switching to local
setpoint mode.
The decimal point setting parameter for the image input (or remote setpoint) is locked and modifies
automatically when the command input decimal point is changed.
7.3 Remote setpoint by serial input
It is possible to enable remote setpoint function selecting en.ser. or en.se.t. on par. 56 rem.s. The
remote setpoint must be written on the word modbus 1249 for the command 1 and 1250 for the
command 2 (with tenth of degree if the command process is a temperature sensor).
It is possible to switch from remote to local sepoint pressing SET for 1 second. In remote setpoint mode
the led REM is ON (if there is serial communication), it flashes when switching to local setpoint mode.
At restarting the controller keeps set in remote setpoint mode (the setpoint value is initialized to 0).

8.2 Aifọwọyi Tune
Automatic tuning procedure allows a precise regulation without delving into the PID regulation
algorithm. Selecting Auto on par. 73 tun.1 (for the regulation loop 1), or on par. 98 tun.2 (for the
regulation loop 2), 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.
8.3 Afowoyi 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 tun.1, or on par. 98 tun.2, the procedure can be activated in three ways:
• 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. (or on par. 239 d.i.2.F., par. 247 d.i.3.F., par. 255 d.i.4.F.). At first activation
of digital input (commutation on front panel) led TUN led switches on and at second activation
yipada si pa.
• Running Tuning by serial input:
Write 1 on word modbus 1216 (command 1) or 1217 (command 2): led TUN switches ON and the
procedure starts. Write 0 to stop the tuning.
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 or par. 99 s.d.t.2)
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.
8.4 Tuning once
Set once on parameter 73 tun.1, or on parameter 98 tun.2.
Autotuning procedure is executed only once at next ATR244 restart. If the procedure doesn’t work, will
be executed at next restart.
22 - ATR244 - Itọsọna olumulo
8.5 Synchronized tuning
Set sYNch. on parameter 73 tun.1 or on parameter 98 tun.2.
This procedure has been conceived to calculate correct PID values on multi-zone systems, where each
temperature is influenced by the adjacent zones.
Writing on word modbus 1216 (for regulation loop 1) or 1217 (for regulation loop 2) the controller
ṣiṣẹ bi atẹle:
Word value Action
0 Tune off
1 Command output OFF
2 Command output ON
3 Tune active
4 Tune completed: command output OFF (read only)
5 Tune not available: softstart function enabled (only reading)
Here below the functioning for regulation loop 1: the master switches-off or turns-on all zones (value
1 or 2 on word 1216) for a time long enough to create inertia on the system.
At this point the autotuning is launched (value 3 on word 1216). The controller executes the procedure
for the calculation of the new PID values. When the procedure ends, the controller switches off the
command output and selects the value 4 on word 1216. The master, who will always read the word
1216, will control the various zones and when all will have finished, will bring to 0 the value of word
1216: the various devices will regulate the temperature independently, with the new calculated values.
The master must read the word 1216 at least every 10 seconds or the controller will automatically
exit the autotuning procedure.
8.6 Digital input awọn iṣẹ
The ATR244 functions related to digital inputs, can be enabled by parameters 231 d.i.1.F., 239 d.i.2.F., 247

it is necessary to select the reference regulation loop.
8.7 Automatic / Manual regulation for % output control
This function allows to switch from automatic functioning to manual command of the output
ogoruntage.
With par. 48 A.ma.1. (for regulation loop 1) or par. 67 A.ma.2. (for regulation loop 2) 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.
8.8 Heater Break Alarm on CT (current transformer – only
on ATR244-13ABC and 23xx-T)
This function allows to measure load current to manage an alarm during a malfunctioning with power
in short circuit, always open or partial break of the charge. To enable this function set 50 Hz or 60 Hz on
par. 287 ct F. and the value of the connected transfomer, on par. 288 ct v..
• Seletct on par. 289 H.b.a.r. the regulation loop referred to the current measure and the Heater Break
Alarm intervention.

8.9 Iṣẹ meji (Itutu-alapapo)
ATR244 is suitable also for systems requiring a combined heating-cooling action.
The command output has to be configured as PID for Heating (Par. 38 ac.t.1 or Par. 57 ac.t.2 = Heat and
P.b. 1 or P.b. 2 greater than 0), and one of the alarms (AL.1.F., AL.2.f., AL.3.f. , AL.4.f. , AL.5.f. or AL.5.F.) has to be
configured as cooL.
The command output must be connected to the actuator responsible for heating, while the alarm will
control cooling action.
Parameters to be configured for the heating PID are:
ac.t.1 or ac.t.2 = Heat Command output action type (Heating);
P.b. 1 or p.b. 2: Heating proportional band;
i.t. 1 or i.t. 2: Integral time of heating and cooling;
d.t. 1 or d.t. 2: Derivative time of heating and cooling;
c.t. 1 or c.t. 2: Heating time cycle.
Parameters to be configured for the cooling PID related to regulation loop 1 and alarm 1 are:
AL.1.F. = cooL. Alarm 1 selection (Cooling);
p.b.m.1: Proportional band multiplier;
o.d.b.1: Overlapping / Dead band;
c.c.t.1: Cooling time cycle.
Par. p.b.m.1 (that ranges from 1.00 to 5.00) determines the proportional band of
cooling action basing on the formula:
Proportional band for cooling action = p.b. 1 x p.b.m.1.
This gives a proportional band for cooling which will be the same as heating band if p.b.m.1 = 1.00, or 5
times greater if p.b.m.1 = 5.00.
Integral and derivative time are the same for both actions.
Par. o.d.b.1 determines the percentage overlapping between the two actions. For systems in which
the heating output and cooling output must never be simultaneously active a Dead Band (o.d.b.1 ≤ 0),
must be configured, vice versa you can configure an overlapping (o.d.b.1 > 0).

8.11 Soft-Start Function
ATR244 is provided with two types of softstart selectable on parameter 264 SS.tY. (“Softstart Type”).
1 First selection (GrAd.) enables gradient softstart. AAt starting the controller reaches setpoint basing
on the rising gradient set on parameter 266 SS.Gr. (“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
agbara.
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
Ogoruntage”) 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.
8.12 Pre-Programmed cycle
This function allows a simple timed work cycle to be programmed and is enabled by setting Enab.
in parameter 263 pr. cY.: the process reaches setpoint 1 (heating) according to the gradient set in
parameter 266 SS.Gr., then rises to maximum power towards setpoint 2. When the process reaches
setpoint 2 it remains in holding for the time set in parameter 270 m a. t.i. (If set to 0, maintenance is not
performed). At the end of the holding time, if parameter 271 FA.Gr. is set to 0, the command output
is disabled and the instrument displays Stop; with parameter 271 FA.Gr. different from 0, the process
goes down to setpoint 3 (cooling) according to the gradient set in the above parameter after which
the command output is disabled and the instrument displays Stop.
1 The tuning procedure starts by exiting the configuration after changing the parameter.

The ATR244 integrates two timers that can be independent, sequential or looped together.
Timer 1 is enabled on parameter 328 tmr.1.; timer 2 on parameter 331 tmr.2.:
ENAB. the timer starts from the keyboard or digital input (user intervention is required)
EN.StA. the timer starts counting when the regulator is in RUN.
The timer time-base set in mm.ss or hh.mm by changing parameters 329 t.b.t.1 for timer 1 and 332 t.b.t.2
for timer 2.
In parameter 334 tMr.S. can be define whether the timers should be independent or related to each
miiran.
SinGL. The timers work independently of each other.
SeQue. When timer 1 ends, timer 2 starts. The sequence is active only by starting timer 1. When
timer 2 expires, the sequence is interrupted.
LooP When a timer ends, another starts: the sequence repeats itself cyclically.
To change the duration of the counting time, follow the steps below:
Press Display Do
1 SET Press until tim. 1 or tim. 2 visualized on
ifihan 1.
2   Digits on display 1 changes. Increase or decrease time value for the
selected timer.
To start the keyboard count follow the steps below:
Press Display Do
1 FNC
Press until tim. 1 or tim. 2 visualized on display 2.
Display 1 shows STOP if the timer is stopped, otherwise
it shows the remaining time.
2 SET The timer stops if active or starts counting if in STOP.
Start/Stop of Timer is possibile also by digital input (see parameters d.i.1.F … d.i.4.F..)
The alarm outputs can be associated with the timers (parameters AL.1.F …. AL.6.F.). On parameters 330
A.tM.1 and 333 A.tM.2 is possible to select the activation mode. The proposed solutions are as follows:
Start Alarm active during timer counting
End Alarm active when the timer expiry

ATR244-xxxxx-T is equipped with RS485 and can receive/broadcast data via serial communication
using MODBUS RTU protocol. The device can only be configured as a Slave. This function enables the
control of multiple controllers connected to a supervisory system / SCADA.
Each controller responds to a Master query only if the query contains the same address as parameter
318 sL.ad. (“Slave Address”).
The addresses permitted range from 1 to 254 and there must not be controllers with the same address
on the same line.
Address 255 can be used by the Master to communicate with all the connected equipment (broadcast
mode), while with 0 all the devices receive the command, but no response is expected.
The baud rate is selected on parameter 319 bd.rt. (“Baud Rate”).
ATR244 can introduce a delay (in milliseconds) of the response to the master request. This delay must
be set on parameter 321 se.de. (“Serial Delay”).
Each parameter modification is saved by the controller in the EEPROM memory (100000 writing cycles),
while the setpoints are saved with a delay of 10 seconds after the last modification.
Changes made to words that are different from those reported in the following table can lead to

on Google Play Store®
The controller ATR244 is supported by the App MyPixsys: using a 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.
Ilana:
• 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 ATR244’s antenna is placed on the frontal panel,
under the function keys.
• 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 identification 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).
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 ATR244 will show a restart request, necessary to update the configuration with the new written
Itọsọna olumulo – ATR244 – 35
modifications; if it does not restart, the ATR 244 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.

12.1 Parameters akojọ functioning
The controller ATR244 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 SEn.1 (mnemonic
visualization) or as P.001 (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.
