Introduction
Thanks for choosing a Pixsys controller.
The ATR401 integrates in a single device all options for sensors reading and
actuators control, beside extended range power supply 24…230 Vac/Vdc.
Thanks to dual universal analogue input and outputs congurable as relay or
SSR, the user or the retailer can reduce stock needs.
The series includes also a model with serial communication RS485/
Modbus-RTU and analogue output 0-10 V, 0/4-20 mA.
The possibility to copy parameterization is simplied by the Memory Cards
with internal battery that do not require power supply for the controller.

4 Electronics Removal
To congure internal Jumpers, remove the electronics by twisting o the
screw on front panel.
Disconnect the device from power supply before starting to
congurate or service it.
5 Electrical wirings
Although this controller has been designed to resist noises in
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.

ATR401 - User manual 19
In this example the command setpoint is the value read on second analogue
input AI2: if par. 19    is selected as (AI1) this becomes main process
(sensor input) and AI2 becomes the setpoint.
If par. 19    is selected as  (AI2) this becomes the main process
(sensor input) and AI1 becomes the setpoint.
NB: Remote setpoint function works only with one of these two settings on
par. 19   
It is possible to switch from remote to local setpoin pressing for a second.
This selection is stored even after subsequent instrument restart.
When remote setpoint is active REM is on, it ashes if local setpoin has been
selected.
7.3 Remote setpoint by serial input
It is possible to enable remote setpoint function selecting  on par. 20
 Remote setpoint has to be wrote on word modbus 5001 (tenth of
degree if the command process is a temperature sensor).
It is possible to switch from remote to local setpoint pressing PRGM .
When remote setpoint is active, REM is on (if there is serial communication), it
ashes if local setpoin has been selected.
At restarting the controller backs to remote setpoint mode (setpoint value is
initialized to 0).
Decimal point setting parameter for remote setpoint input is
locked and it is automatically changed when command input
decimal point variates.
8 Controller Functions
8.1 Modication of main and alarm setpoint value
Setpoint value can be modied from keyboard as follows:
Press Display Do
1Value on display 2 changes. Increases or decreases the
main setpoint.
2SET Visualize alarm setpoint on
display 1.
3Value on display 2 changes. Increases or decreases the
alarm setpoint value.

8.2 Auto-Tuning
Tuning procedure to calculate regulation parameters can be manual or
automatic and according to selection on parameter 28 .
8.3 Manual Tuning
Manual procedure allows the user more exibility on deciding when to update
regulation parameters of P.I.D. algorithm.
Press key
FNC
until display 1 visualizes writing  and display 2 visualizes .
Pressing , display 2 visualizes . Led TUN switches on and procedure starts.
8.4 Automatic Tuning
Automatic tuning starts when the controller is switched-on or when setpoint
value has been modied over 35%.
To avoid overshooting, the threshold where controller calculates new P.I.D.
parameters is determinated by setpoint value minus “Set Deviation Tune”
value (see parameter 29 ). To interrupt Tuning keeping the P.I.D. values
unchanged, press key FNC until display 1 visualizes writing  and display
2 visualizes . Pressing , display 2 visualizes , led TUN switch o and
procedure ends. Setting  on parameter 28  autotuning procedure
starts only once when instrument is switched on: after calculating P.I.D.

8.5 Automatic / Manual Regulation for % Output
Control
This function allows to switch from automatic functioning to manual control of
output porcentage. With parameter 83 , it is possible to select two modes.
1 First selection ( ). Pressing key FNC display 1 visualizes writing  on
display 1, while display 2 visualizes . Press key to select manual
mode . Whit and change output percentage. To return to
automatic mode with the same procedure select  on display 2: led
MAN switches on and operation returns to automatic mode.
2 Second selection ( ). Enable the same functioning, but with two
important variants:
• In case of power failure or after a switch-o, at restart both the manual
functioning and the previously xed output percentage value will be
maintained.
• If during automatic functioning there is a sensor failure, controller will
automatically switch to manual mode while maintaining command output
percentage unchanged as generated by P.I.D. immediately before failure.
