Safety Guidelines; Organization Of Safety Notices; Safety Precautions - Pixsys ATR244-12ABC Manual De Instalación

Introduction
The process controller ATR244 stands out for the bright display which ensures optimal visibility and
increased level of information for the operator beside a scrolling Help function.
ATR244 relies on Pixsys flagship programming mode by NFC/RFID technology with dedicated App
MyPixsys for Android devices (same already used for Pixsys signal converters and STR indicators) not
requiring wirings and power supply, allowing quick set-up/updates on site.
Availability include a model with dual analogue input and dual analogue output for maximum
flexibility of applications. It is possible to achieve two separate heating/cooling PID control loops in
one device or to handle mathematical operations between two process values.
The outputs can be selected as command/multiple alarm modes/analogue retransmission. Serial
communication standard is RS485 with Modbus RTU/Slave protocol. Useful power supply with
extended range 24 to 230VAC / VDC with galvanic insulation of the net for the single loop version,
while the model with double analogue input provides two versions: 115 / 230 VAC or 24 VAC / VDC.

Safety Precautions

This product is UL listed as open type process control equipment.
If the output relays are used past their life expectancy, contact fusing or burning may
occasionally occur.
Always consider the application conditions and use the output relays within their
rated load and electrical life expectancy. The life expectancy of output relays varies
considerably with the output load and switching conditions.
Loose screws may occasionally result in fire.
For screw terminals of relays and of power supply, tighten screws to tightening torque
of 0,51 Nm. For other terminals, tightening torque is 0,19 Nm
