Thank you for choosing a Pixsys controller.
Controller DRR245 is specifically conceived for application on control
panels with DIN rail mounting.
Pixsys makes available in a single device all the options relevant to
sensor input and actuators command, in addition to the extended
power range 24…230 Vac/Vdc. With 18 sensors to select and outputs
configurable as relay, SSR command, 4…20 mA and 0…10 Volt, the
user or retailer can reduce warehouse stock by rationalising investment
and device availability.
The series is equipped with serial communication RS485 Modbus RTU
and with a loading control function via the amperometric transformer.
The configuration is further simplified by the Memory cards which are
equipped with internal battery and therefore don’t require cabling to
power the controller.

5.1 Wiring diagram
Although this controller was designed to resist
noises in industrial environments, pease notice
following safety guidelines:
• Separate the feeder line from the power lines.
• Avoid placing near units with remote control
switches, electromagnetic contactors, high
powered motors and in all instances use
specific filters.
• Avoid placing near power units, particularly if
phase controlled.

EN 14
7.2 Auto-Tune
The Tuning procedure calculates the controller parameters and can be
manual or automatic according to selection on parameter 57 ).
7.3 Manual Tuning
The manual procedure allows the user greater flexibility to decide when
to update P.I.D. algorithm work parameters. The procedure can be
activated in two ways.
• By running Tuning from keyboard:
Press the key until display 1 shows the writing with
display 2 showing , press , display 2 shows .
The led switches on and the procedure begins.
• By running Tuning from digital input:
Select on parameter 61 .
On first activation of digital input (commutation on front panel) the
led switches on and on second activation switches off.
7.4 Automatic Tuning
Automatic tuning activates when the controller is switched on or when
the setpoint is modified to a value over 35%.
To avoid an overshoot, the treshold where the controller calculates the
new P.I.D. parameters is determined by the setpoint value minus the
“Set Deviation Tune” (see parameter 58 ).
To exit Tuning and leave the P.I.D. values unchanged, just press the
key until display 1 shows the writing with the display
showing , press , display 2 shows .
The led switches off and the procedure finishes.

15 EN
7.5 Soft-Start
To reach the setpoint the controller can follow a gradient expressed in
units (example: Degree / Hours).
Set the increase value in parameter 62 with the desired
Units / Hours; only on subsequent activation the controller uses the
Soft-Start function.
If parameter 59 is set on and parameter 63 is
different from 0, after switch-on and elapsing of the time set on parameter
63, setpoint does not follow the gradient anymore, but it reaches final
setpoint with maximum power.
Autotuning does not work when Soft-Start is activated: otherwise if
parameter 63 is different from 0 and parameter 57 is set
on , Autotuning starts when Soft-Start time is finished.
If parameter 57 is set on , the Autotuning can be started
only when Soft-Start finishes.
7.6 Automatic / Manual Regulation for % Output Control
This function allows to select automatic functioning or manual command
of the output percentage.
With parameter 60 , you can select two methods.
1 The first selection ( )allows you to enable the key
with the writing on display 1, while display two shows .
Press the key to show ; it is now possible, during the
process display, to change the output percentage using the keys
and . To return to automatic mode, using the same procedure,
select on display 2: the led switches off and
functioning returns to automatic mode.
2 The second selection ( )enables the same functioning,
but with two important variants:
• If there is a temporary lack of voltage or after switch-off, the manual
functioning will be maintained as well as the previously set output
percentage value.
• If the sensor breaks during automatic functioning, the controller
moves to manual mode while maintaining the output percentage
command unchanged as generated by the P.I.D. immediately before
breakage.

EN 16
7.7 Pre-Programmed Cycle
The pre-programmed cycle function activates by setting
or in parameter 59 . First option ( ):
the controller reaches setpoint1
basing on the gradient set in
parameter 62 , then it
reaches maximum power up to
setpoint 2. When the process
reaches maximum power, this
setpoint is maintained for the
time set in parameter 63 .
On expiry, the command output is disabled and the controller displays
. The cycle starts at each activation of the controller, or via
digital input if it is enabled for this type of functioning (see parameter
61 ).
Second option ( ):
start-up is decided only on
activation of the digital input,
according to the setting of
parameter 61 .
On start-up, the controller reaches
setpoint 1 basing on the gradient
set in parameter 62 .
When the process reaches this
gradient, it is maintained for the time set in parameter 63 .
On expiry, the command output is disabled and the controller displays
.

7.8 Memory Card (optional)
Parameters and setpoint values can be duplicated from one controller to
another using the Memory card.
There are two methods:
• With the controller connected to the power supply.
Insert the memory card when the controller is off.
On activation display 1 shows and display 2 shows
(only if the correct values are saved in the memory card).
By pressing the key display 2 shows , then confirm using
the key. The controller loads the new data and starts again.
• With the controller not connected to 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 buttons.
When writing the parameters, the led turns red and on completing
the procedure it changes to green. It is possible to repeat the
procedure without any particular attention.

EN 18
Updating Memory Card
To update the memory card values, follow the
procedure described in the first method, setting
display 2 to so as not to load the parameters
on controller2.
Enter configuration and change at least one
parameter.
Exit configuration. Changes are saved automatically.

8 LATCH ON Functions
For use with input (potentiometer 6 KΩ) and (potentiometer
150 KΩ) and with linear input (0…10 V, 0...40 mV, 0/4…20 mA), you can
associate start value of the scale (parameter 6 ) to the minimum
position of the sensor and value of the scale end (parameter 7 )
to the maximum position of the sensor (parameter 8 configured
as ).
2If on activation the controller does not display it means no data have been
saved on the memory card, but it is possible to update values.

19 EN
It is also possible to fix the point in which the controller will display 0
(however keeping the scale range between and )
using the “virtual zero” option by setting or in
parameter 8 .
If you set the virtual zero will reset after each activation of the tool;
if you set the virtual zero remains fixed once tuned.
To use the LATCH ON function configure as you wish
the parameter 3.
For the calibration procedure refer to the following table:

8.1 Loop Break Alarm on Amperometric Transformer T.A.
This function allows to measure load current and to manage an alarm
during malfunctioning with power in short circuit or always off. The
amperometric transformer connected to terminals 15 and 16 must be
50mA (sampling time 80 ms).
• Set scale end value of the amperometric transformer in Amperes on
parameter 47 .
• Set the intervention threshold of the Loop Break Alarm in Amperes on
parameter 48 .
• Set the intervention delay time of the Loop Break Alarm on
parameter 49 .
• You can associate the alarm with a relay by setting the parameter
, or as .
If a remote control switch or SSR remains closed, the controller signals
the fault by showing on display 2 (alternatively with a command
setpoint).
If instead the power stage remains open, or the load current is lower than
the value set on , the controller shows on display.
You can display the current absorbed during the closure phase of the
power stage.
