6 STR550 - User manual
Introduction
Thanks for choosing a Pixsys device.
STR550 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 outputs 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
LCD display 128x64pixel with backlighting programmable for 7 colors.
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.
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.

8 Controller Functions
8.1 Memory Card (optional)
Parameters and setpoint values can be duplicated from one controller to another
using the Memory card.
2 modes are available:
t
With the controller connected to the power supply: :
Insert memory card when the controller is o. On activation the LCD visualizes
Load data
and
Esc
in correspondence of the relative keys (only if the correct
values are saved in the memory card). Pressing
Load data
the controller loads the
new values. Pressing
Esc
the device keeps the old values.
t
With the controller not connected to the power supply:
The memory card is equipped with an internal battery with an autonomy of about
1000 uses (2032 button battery, replaceable).
Insert the memory card and press the programming button. When writing the
parameters, led turns red and on completing the procedure it changes to green. It
is possible to repeat the procedure without any particular attention.
NB : it is not possible to transfer the parameters of a device to one with dierent
code: the LED lights red.
Updating Memory Card .
To update the memory card values, follow the procedure described on
rst mode, pressing
Esc
so as not to load the parameters on controller.
Enter conguration and change at least one parameter. Exit conguration.
Changes are stored automatically.

For the use with input Potentiometers max.6 kohm and Pot.max.150 kohm and
with linear input (0..10 V, 0..60 mV, 0/4..20 mA), it is possible to associate the start
value of the scale (par. 4
Lower limit V/I ) to the minimum position of the sensor
and the value of end scale (par. 5
Upper limit V/I ) to the maximum position of the
sensor.

8.4 Digital input functions
On the STR550 model, digital inputs can be enabled by conguring the par. 95
Digital input 1 and the par. 100 Digital Input 2.
t Run : allows the action of relays and linear output.
t
Hold : locks the conversion.
t
Tare zero (AI) : selects to zero the process value (tare function).
t
Alarm reset: if one or more alarms are selected with manual reset and alarm
conditions are no longer present, closing the digital input it is possible to
restore the alarm output.
t
Totalizer reset : if the totalizer function is active, using the digital input it is
possible to reset the counter.
t
Peaks reset : min. peak/max. peak/peak-to-peak values are reset.
t
Sum total : if the sum function is active, using the digital input it is possible to
increase the “sum” counter as indicated by the process value.
t
Sum reset : if the sum function is active, using the digital input it is possible to
reset the “sum” counter.
t
Cong. lock : if the digital input is active it is not possible to enter conguration
or to modify the setpoints.
Selecting
Digital input 1 or Digital input 2 on the alarm parameters, the related
relays will activate togheter with the digital input; functions selected on
parameters 95 and 100 will continue to work.
8.5 Peak values
The STR550 is provided with a page for
the visualization of peak values: max.
peak, min. peak and peak-to-peak of
analogue input. Keeping pressed
Rst
it
is possible to reset the visualized values.

20 STR550 - User manual
8.6 Totalizer function
The totalizer function, which can be enable by par. 9 Totalizer, performs an instant
measurement of the process and sums it on a time basis to the previously totalized
value.
On the dedicated page it is possible to
see the instant process value and the
totalized value: keeping pressed
Rst
it is
possible to reset this value.
Ex.: if a sensor 4..20mA with F.s. 9000m
3
/hour is connected, it is necessary to select
Hour on par. 9 Totalizer. The device will increase the totalized value considering
the m
3
owing each second (2.5m
3
).
8.7 Sum function
The sum function, which can be enabled by par. 10 Sum function, allows to increase
a counter adding the process value on command. It is an application typical for
weighing systems and allows to know the total weighed value.
Press
Sum Function
to enter the
function page. Pressing
+
the Process
value is added to the counter. It is
possible to reset the total value keeping
pressed
Rst
and to x “tare zero” of the
process pressing
Tar
.
Functions tare, sum and reset can be managed also by digital input if enabled on
par. 95
Digital Input 1 and par. 100 Digital Input 2 .
