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. Thanks to 18 selectable sensors and outputs congurable 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 the amperometric transformer. The
possibility to repeat parametrization is simplied by the Memory Cards with
internal battery that do not require power supply for the controller.

5 Conguration EASY-UP
To simplify the setting of parameters and the integration of the dierent com-
ponents involved in the control system, Pixsys introduces the EASY-UP coding
which allows to set sensors and/or command outputs in one single step.
By means of the code listed in the data sheet enclosed to the sensor or actuator
(SSR, motorized valve, etc.) the EASY-UP coding will set the relevant main pa-
rameters on the controllers (ex. selection of PT100 on parameter “Sensor” and
the corresponding measuring range on parameters “Lower and Upper limits
of the setpoint”).
Dierent codes may be entered on the controllers in sequence to congure
inputs, control output or retransmission of signal.

7.2 Auto-Tuning
The Tuning procedure calculates the controller parameters and can be manual or
automatic according to selection on parameter 57 ( tunE ).
7.3 Manual Tuning
The manual procedure allows the user greater exibility to decide when to
update P.I.D. algorithm work parameters. The procedure can be activated in
two ways.
• By running Tuning by keyboard:
Press the key until display 1 shows the writing
tunE with display 2 show-
ing off , press , display 2 shows on .
The TUN led switches on and the procedure begins.
• By running Tuning by digital input:
Select tune on parameter 61 dGt.i. On rst activation of digital input (com-
mutation on front panel) the TUN led switches on and on second activation
switches o.
7.4 Automatic Tuning
Automatic tuning activates when the controller is switched on or when the
setpoint is modied 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 58 S.D.tu. ).
To exit Tuning and leave the P.I.D. values unchanged, just press the key until
display 1 shows the writing tune with the display showing on , press , display
2 shows off . The TUN led switches o and the procedure nishes.

20 - ATR243 - User manual
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 62 GrAd. with the desired Units/Hours; only
on subsequent activation the controller uses the Soft-Start function.
If parameter 59 op.mo. is set on cont. and parameter 63 ma.ti. is dierent from
0, after switch-on and elapsing of the time set on parameter 63, setpoint does
not follow the gradient anymore, but it reaches nal setpoint with maximum
power.
Autotuning does not work when Soft-Start is activated: otherwise if parameter
63
ma.ti. is dierent from 0 and parameter 57 tune is set on auto , Autotuning
starts when Soft-Start time is nished.
If parameter 57 tune is set on man. , the Autotuning can be started only when
Soft-Start nishes.
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. , you can select two methods.
1 The rst selection ( en. ) allows you to enable the key with the writing p.-
--
on display 1, while display two shows Auto .
Press the key to show Man. ; it is now possible, during the process display,
to change the output percentage using the keys and . To return to au-
tomatic mode, using the same procedure, select Auto on display 2: the led
MAN switches o and functioning returns to automatic mode.
2 The second selection ( EN.ST, ) enables the same functioning, but with two
important variants:
• If there is a temporary lack of voltage or after switch-o, the manual fun-
ctioning 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 unchan-
ged as generated by the P.I.D. immediately before breakage.
