Introduction
Thank you for choosing a Pixsys controller.
With the ATR142 model Pixsys makes available in a single
device multiple options related to sensor input and actuators
command in addition to the extended power range 24…230
Vac/Vdc. With 17 sensors to select and outputs congurable
as relay or SSR command, the user or retailer can reduce
stock by rationalising investment and device availability. The
series includes a version equipped with serial communication
RS485 Modbus. The conguration is further simplied by the
Memory cards which are provided with internal battery and
therefore do not require cabling to power the controller.

 Conguration EASYUP
To simplify the setting of parameters and the integration of
the dierent components involved in the control system,
Pixsys introduces the EASY-UP coding which allows to set
sensors and/or command outputs in a 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 parameters on the control-
lers (ex. selection of PT100 on parameter “Sensor” and the
corresponding measuring range on parameters “Lower and
Upper limits of setpoint”)
Dierent codes may be entered on the controllers in sequen-
ce to congure inputs, control output or retransmission of
signal.

when to update PID algorithm parameters. The procedure
can be activated in two ways.

. Automatic Tuning
Automatic tuning activates whenever the controller is switched
on or when the setpoint is modied to a value over 35%.
To avoid an overshoot, the threshold where the controller
calculates new PID parameters is determined by the setpoint
value minus the “Set Deviation Tune” (Parameter 47
s.d.tu. ).
To exit Tuning and keep PID values unchanged, just press the
FNC

When writing the parameters, the led turns to red and on com-
pleting the procedure it turns to green. It is possible to repeat
the procedure without any particular attention.

Updating Memory Card
To update the memory card values, follow the procedure
described for the rst method, setting display 2 to ---- so as
not to load the parameters on controller.
Enter conguration level and change at least one parameter.
Exit conguration. Changes are saved automatically.
 If on activation the controller does not display
memo it means no data
have been saved on the memory card, but it is possible to update values.
