Introduction
Thanks for choosing a Pixsys device.
STR561 is an indicator/panel meter for acquisition and retransmission of
processes, also with fast transient. It is provided with relay outputs for alarm
purpose, analogue output for retransmission of process / setpoints and
programmable digital inputs.
Available in standard format 96x48mm, the device can be congured both for
horizontal and vertical mounting.
Distinctive feature is the intuitive multilingual interface, supported by a graphic
OLED monocromatic yellow display 128x64 pixel.
Visualization options include bargraph and process trend with programmable
sampling time.
Software features include mathematical functions related to process value like
totalizer and sum.
Serial connectivity relies on RS485 and Modbus-RTU protocol.
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.

Although this controller has been designed to resist noises in an industrial
environment, 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.
For permanently connected equipment:
• supply wiring must be ≥18 Awg with cables suitable for temperatures > 70 ° C;
• for requirements about any external switch or circuit-breaker see EN 61010-1
par. 6.11.3.1 and about external overcurrent protection devices see EN
61010-1 par. 9.6.2; the switch or circuit-breaker must be near the equipment.

7. 3 Calibration function
This function allows to activate a eld calibration of linear input for strain-gauge
or potentiometer. Dierent calibration options are available and may be
selected by parameter, according to type of sensor/transducer and its relevant
application. To activate calibration procedure, enter conguration mode, select
the parameters group “Analogue Inp.”, select Calibration parameter and chose
one of the available options pressing “Sel”. Following calibration options are
available:

User manual - STR561 - 17
• Sampling value. This proceeding performs a calibration of the analogue input
on two points of the scale taking as reference two known values (for example
for a load cell these values could be Zero balance and Reference weight). It
is possible to link the calibration lower limit (parameter 6 Lower lim.) to the
minimum value of the sensor or to the minimum position of the potentiometer
while the calibration upper limit (parameter 7 Upper lim.) may be linked to the
max value of the sensor or the maximum position of the potentiometer.

• Full scale % value. This proceeding is available for 6wires (4wires+2 wires
calibration) strain-gauge sensors and for Melt transducers. It is possible to
calibrate reading of analogue input by choosing the percentage of the full
scale value at which the calibration of the upper limit will be performed. At
rst the operator will be asked to select the percentage for the calibration
of the upper limit. Afterwards the lower limit value and upper limit value
(% of full scale value) will also be calibrated, as for the sampling value. The
two calibration wires of the sensor can be connected to relay of output Q2 to
perform a semi-automatic calibration. In this case it is necessary to select the
option Calibration % on parameter Alarm 2 - Type of alarm. If contact Q2 will
not be used to generate sensor calibration signal, it is possible to short-circuit
externally the two wires, waiting for stabilization of reading on the device and
then proceeding to calibration of upper limit.
