1Introduction
Thank you for choosing a Pixsys controller.
The ATR236 model allows the connection of several temperature
sensors, ON/OFF regulation with hysteresis or P.I.D. with autotuning and
selection of different types of alarm, in addition to the extended power
range 24…230 Vac/Vdc.
The configuration is simplified by the Memory cards which are equipped
with internal battery and therefore don’t require cabling to power the
controller.

Although this controller has been designed to resist
noises in an industrial environments, please notice
the following safety guidelines:
• Separate control lines from the power wires.
• Avoid the proximity of remote control switches,
electromagnetic meters, powerful engines.
• Avoid the proximity of power groups, especially
those with phase control.

7Controller Functions
7.1 Modofying Main Setpoint and Alarm Setpoint Values
Press Display Do
1or Value on display 2
changes.
Increases or decreases
the main setpoint.
2
SET
Visualize alarm setpoint
on display 1 value
being inserted.
3or Value on display 2
changes.
Increases or decreases
the alarm setpoint value.
The setpoint value can be changed from the keyboard as follows:
7.2 Auto-Tuning
The Tuning procedure calculates the controller parameters and can be
manual or automatic according to selection on parameter 31 .
7.3 Manual Tuning
The manual procedure allows the user greater flexibility to decide when
to update P.I.D. algorithm work parameters. The procedure can be
activated by keyboard:
Press the key until display 1 shows the writing with
display 2 showing , press , display 2 shows .
The led switches on and the procedure begins.

13 EN
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 the
new P.I.D. parameters is determined by the setpoint value minus the
“Set Deviation Tune” (see parameter 32 ).
To exit Tuning and leave the P.I.D. values unchanged, just press the
key until display 1 shows the writing with the display
showing , press , display 2 shows .
The led switches off and the procedure finishes.
7.5 Soft-Start
To reach the setpoint the controller can follow a gradient expressed in
units (example: Degree / Hours).
Set the increase value in parameter 34 with the desired
Units / Hours; only on subsequent activation the controller uses the
Soft-Start function.
Autotuning does not work when Soft-Start is activated: otherwise if
parameter 31 is set on , Autotuning starts when Soft-
Start time is finished.
7.6 Automatic / Manual Regulation for % Output Control
This function allows to select automatic functioning or manual command
of the output percentage.
With parameter 33 , you can select two methods.
1 The first selection () allows you to enable the key
with the writing on display 1, while display two shows .
Press the key to show ; it is now possible, during the
process display, to change the output percentage using the keys
and . To return to automatic mode, using the same procedure,
select on display 2: the led switches off and
functioning returns to automatic mode.
2 The second selection () enables the same functioning,
but with two important variants:

EN 14
• If there is a temporary lack of voltage or after switch-off, the manual
functioning will be maintained as well as the previously set output
percentage value.
• 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.
7.7 Memory Card (optional)
Parameters and setpoint values can be duplicated from one controller to
another using the Memory card.
There are two methods:
• With the controller connected to the power supply.
Insert memory card when the controller is off.
On activation display 1 shows and display 2 shows
(only if the correct values are saved in the memory card).
By pressing the key display 2 shows , then confirm using
the key. The controller loads the new data and starts again.

15 EN
• With the controller not connected to power supply.
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, the led turns red and on completing the
procedure it changes to green. It is possible to repeat the procedure
without any particular attention.
1If on activation the controller does not display it means no data have been
saved on the memory card, but it is possible to update values.
