Introduction
Thank you for choosing a Pixsys controller.
With the ATR227 Pixsys 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 the various selectable sensors and the output
congurable as relay or SSR command, the user or retailer can reduce stock by
rationalising investment and device availability
1 Safety guide lines
Read carefully the safety guidelines and programming instructions contained in
this manual before using/connecting the device. Disconnect power supply before
proceeding to hardware settings or electrical wirings. Only qualied personnel should
be allowed to use the device and/or service it and in accordance to technical data and
environmental conditions listed in this manual. Do not dispose electric tools together
with household waste material. In observance European Directive 2002/96/EC 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.

5 Electrical wirings
This controller has been designed and manufactured in conformity to Low Voltage
Directive 2006/95/EC , 2014/35/EU (LVD) and EMC Directive 2004/108/EC, 2014/30/
EU (EMC). For installation in industrial environments please observe following safety
guidelines:
• Separate control line from power wires.
• Avoid proximity of remote control switches, electromagnetic contactors, powerful
engines and use specic lters.
• Avoid proximity of power groups, especially those with phase control.
• It is strongly recommended to install adequate mains lter on power supply of
the machine where the controller is installed, particularly if supplied 230Vac. The
controller is designed and conceived to be incorporated into other machines,
therefore CE marking on the controller does not exempt the manufacturer of
machines from safety and conformity requirements applying to the machine itself.

5.1.a Power Supply
Switching power supply with extended range 24..230 Vac/dc
±15% 50/60 Hz – 5,5 VA (galvanically insulated).
5.1.b AN1 Analogue Input
For thermocouples K, S, R, J, T, E, N, B.
• Comply with polarity
• For possible extensions, use compensated cable
and terminals suitable for the thermocouples
used(compensated)
• When shielded cable is used, it should be grounded at one
side only
For thermoresistances PT100, Ni100.
• For the three-wire connection use wires with the same
section
• For the two-wire connection short-circuit terminals 1 and 3.
• When shielded cable is used, it should be grounded at one
side only
