5 Electrical wirings
This controller has been designed and manufactured in conformity to Low Voltage
Directive 2006/95/EC , 2014/35/EU (LVD) and EMC Directive 2004/108/EC, 2014/30/
EU (EMC). For installation in industrial environments please observe following safety
guidelines:
• Separate control line from power wires.
• Avoid proximity of remote control switches, electromagnetic contactors, powerful
engines and use specic lters.
• Avoid proximity of power groups, especially those with phase control.
• It is strongly recommended to install adequate mains lter on power supply of
the machine where the controller is installed, particularly if supplied 230Vac. The
controller is designed and conceived to be incorporated into other machines,
therefore CE marking on the controller does not exempt the manufacturer of
machines from safety and conformity requirements applying to the machine itself.

7 Controller Functions
7.1 Modifying Main Setpoint and Alarm Setpoint Values
Setpoint value can be modied by keyboard as follows:
Press Display Do
1
c
or
d
Value on display 2 changes. Increase or decrease main setpoint.
2SET Visualizes alarm setpoint on
display 1.
3
c
or
d
Value on display 2 changes. Increase or decrease the alarm
setpoint value.
7.2 Auto-Tuning
Tuning procedure to calculate regulation parameters can be manual or automatic
according to selection on parameter 8 (P.i . d .).
7.3 Manual Tuning
Manual procedure allows the user a greater exibility to decide when to update PID
algorithm parameters. After selected MAn . on parameter 8 (P.i . d .), the procedure can
be activated in two ways:
• Running Tuning by keyboard:
Press SET until display 1 shows the writing tunE with display 2 showing o FF
, press
c
, display 2 shows on.
TUN led switches on and the procedure starts.
• Running Tuning by digital input:
Select
tunE on parameter 25 d G t.i . At rst activation of digital input (commutation
on front panel) TUN led switches on while at second activation switches o.

12 - ATR227 - User manual
7.4 Automatic Tuning
Automatic tuning procedure has been conceived to give user the possibility to have a clear
regulation also without knowledge of PID regulation algorithm. Setting Au to on parameter
8 P.i . d . , the controller will check process oscillations and will modify PID parameters.
7.5 Soft-Start
At starting the controller can follow a gradient expressed in units (ex. Degree/Hour) to
reach the setpoint. Enter this gradient on parameter 21 SFt.G. with the chosen units/hour:
at next activation the controller will execute the Soft-Start function.
If parameter 24 S . ti M . is dierent from 0, after switch-on and elapsing of the time set
on parameter 24 , setpoint does not follow the gradient anymore, but it reaches nal
setpoint with maximum power.
7.6 Automatic/Manual Regulation for % Output Control
This function allows to select automatic functioning or manual command of the
output percentage.
By parameter 69 Au.ma. it is possible to select two modes.
1 First selection (en.) pressing SET display 1 shows p.--- , while on display 2 appears
auto.
Press
c
to select man
mode; it is now possible to modify the output percentage
using
c
and
d
. To back to automatic mode, using the same procedure, select auto
on display 2: MAN led switches o and functioning backs to auomatic.
2 Second selection (en.st.) enables the same functioning, but with two important
variants:
• If there is a temporary power failure or after switch-o, manual functioning as well as the
previous output percentage value will be maintained at restarting.
• If the sensor breaks during automatic functioning, controller moves to manual mode
while maintaining the output percentage command unchanged as generated by the PID
immediately before breakage.
Ex: on an extruder the resistance percentage command (load) is kept also in case of
input sensor failure.
7.7 Digital input functions
On ATR227 digital input can be enabled by parameter 25 d G t .i .
• 2.SPv .: Switch between two setpoint thresholds: with digital input active ATR226
regulates on SET2, otherwise on SET1;
• ru n .: Regulation is enabled only with digital input active;
• tune: Enables/disables Tuning, if parameter 8 P.i . d . is set on man.
;
• au.ma.
: (Automatic/Manual) if par. 19 au.ma.
is set on en. or en.st., ATR227 regulates
in manual mode if digital input active, otherwise the regulation is automatic..
• Act. t.: (Action Type) heating regulation with inactive digital input; Cooling
regulation with active digital input;
• o . rSt: (Outputs Reset) allows to reset the outputs if Manual reset should be
congured for command output and/or alarm outputs.

User manual - ATR227 - 13
7.8 Memory Card (optional)
Parameters and setpoint values can be easily copied from one controller to others
using the MEMORY CARD.
Enter the Memory Card with the controller not connected to power supply.
At starting display 1 visualizes memo while display 2 visualizes S ki P (only if into the
Memory are stored correct values). Pressing
c
display 2 visualizes Lo a d. Press SET to
conrm. The controller loads the new values and restarts.
NB: parameters may be copied only on controllers of the same model!
Updating Memory Card.
To update the memory card values, follow the procedure previously described, setting
S ki P on display 2 so as not to load the parameters on controller.1
Enter conguration (password 1234): Exiting conguration mode, the settings will be
automatically saved on Memory card.
7.9 Regulation control (only on ATR227-12ABC)
ATR227 integrates dierent types of control for the regulation of the SSR command
output, selecting parameter 43 o.cL.t.
as follows:
7.9.a
ti M E
Time control
For this type of control it is suggested to use a “zero-crossing” SSR.
Activation and deactivation of the output is related to the time selected on parameter
52 c. t.. Ex. selecting a time of 10s and supposing a 30% percentage, the output will
remain active for 3s and inactive for 7s.
7.9.b
b S t . F.
Burst re control
For this type of control it is necessary to use a “Non zero-crossing” SSR.
The “Burst-re” control (1 cycle) is a duty cycle mode which consists of supplying a
series of complete mains voltage cycles to the load.

At 50% power, the modulation time is
40ms:
• 1 ring cycle (20ms at 50Hz)
• 1 ring cycle (20ms at 50Hz)
For a setpoint less than 50%:
• The ring time remains constant (1 cycle)
• The non-ring and modulation time
increases
For a setpoint greater than 50%:
•
The non-ring time remains constant (1 cycle)
• The ring and modulation time increases.
1 In the event that, when turned on, the controller do not see memos, it means that there are no data on the
Memory Card, but you can also update their values.

7.9.c

Advanced Burst re control
For this type of control it is necessary to use a “Non zero-crossing” SSR.
In order to minimise power uctuation during the modulation period, the
“advanced Burst re” SSR output ring mode uses:
· A complete number of cycles for ring
· A complete number of half-cycles for non-ring

For a percentage less than 66%, SSR output
ring takes place as in the “Burst re” mode
(see b S t . F. )
For a setpoint greater than 66% in
“Advanced Burst re” mode:
· The non-ring time is constant at one
half-cycle
· Firing takes place over whole cycles.
In a ‘short-wave infrared’ application,
‘advanced Burst re’ ring mode reduces the
brightness of the infrared elements and thus
minimises annoying visual ickering.
In a short-wave infrared application, “advanced Burst re” ring mode reduces the
brightness of the infrared elements and thus minimises annoying visual ickering.
7.9.d
PHs .A.
Phase angle control
For this type of control it is necessary to use a “Non zero-crossing” SSR.
If this mode is active, the regulation is done through the phase choking
25% Power
50% Power
75% Power
100% Power
Using a no zero-crossing SSR, the ATR227
synchronizes with the power supply volage
(necessarily AC) and determines when
to activate the output to create the right
choking.
7.9.e
F.PH.A.
Fixed Phase angle control
For this type of control it is necessary to use a “Non zero-crossing” SSR.
If this mode is active, the regulation is done as per “time control” (ti M E ), but during the
activation it is managed a xed choking selected on parameter 45 F.P.A.P..
