PID controller's size 48 x 48 mm
Controller designed to display and control the process, with tight adjustment PID control, in appliances
where accuracy is required, like water or oil cooling systems, furnaces, gas burners, plastic injection
machinery, etc.
Input for type 4-20 mA, Pt100 sensors, Thermocouple J or Thermocouple K. Relay outputs may be used for
control and/or alarm. It also has a logic output/input for control/alarm.
1- Versions and references
2- Installation
The controller should be installed in a place protected from vibrations, water and corrosive gases, and
where ambient temperature does not surpass the value specified in the technical data.
In order for the controllers to have IP55 protection, the gasket should be properly installed between the
apparatus and the perimeter of the panel cut-out where it is to be fitted.
In order to give a correct reading, the probe should be installed in a place without heat influences other
than the temperature that is to be measured or controlled.
2.1-Fastening
To fix the unit, place the fasteners in the top and the
lower parts and press them to enter in the controller
lateral sliders. Move the fasteners in direction to the
panel until the controller is fixed.
2.2- Connection
The probe and its lead should
NEVER
be installed in
ducting along with power, control or power supply
wiring.
The power supply circuit should be connected with a
minimum 2 A, 230 V, switch located close to the unit.
2
Power supply cables should be H05VV-F 2x0,5 mm
2
or H05V-K 2x0,5 mm .Section of connecting wires for
2
2
relays contacts should range from 1 mm to 2,5 mm .
For the 4-20 mA control input, it is necessary to
connect the 2.49
W
resistance supplied between
terminals 10 and 11.
3- Adjustment and configuration
It should only be programmed or modified by personnel
who are fully conversant with the equipment operation
and possibilities.
3.1 Set Point temperature.
The factory SET POINT default value is 0,0 ºC.
-Press
PRG
key for at least 3 seconds to CHANGE SET POINT SP1 or SP2. It displays SP1.
-Press
N
or
Q
keys to SELECT SET POINT 1 or 2.
-Press
SET
key to CHANGE SELECTED SET POINT. It displays the CURRENT SET POINT value.
-Press
N
or
Q
keys to CHANGE SET POINT into the required value.
-Press
SET
key to ACCEPT THE NEW SET POINT. The display returns to the CURRENT TEMPERATURE
display status.
3.2 Parameters configuration
Level 1 Menus
-Press
PRG
key for at
least 10 seconds. We are
in the programming LE-
VEL 1 MENUS and the
first menu “
SPCF
” is dis-
played.
-Press
N
key to access the next menu and
Q
key to return to the previous one.
-Press
PRG
key, the controller returns to the CURRENT TEMPERATURE display status.
When
PAS
is displayed, PASSWORD programmed in
PAS1
parameter of
PAr
menu should be entered
to access programming LEVEL 1 MENUS.
-Press
N
or
Q
keys to CHANGE NUMBER and DISPLAY PASSWORD programmed.
-Press
SET
key to ACCEPT PASSWORD. The first menu “
SPCF
” will be displayed.
Level 2 Parameters
-In the desired menu of LEVEL 1 MENUS, press key
SET
. LEVEL 2 PARAMETERS programming is accessed.
The first parameter of the selected menu is displayed on the screen.
-Press
N
key to access the next parameter and
Q
key to return to the previous one.
-Pressing
PRG
key, returns to the LEVEL 1 MENUS.
Level 3 Values
-Press the
SET
key to enter
and modify the desired para-
meter.
-Press
N
or
Q
keys to
CHANGE VALUE.
-Pressing
SET
key, ACCEPT
THE NEW VALUE and it
returns to LEVEL 2 PARA-
METERS.
-Pressing
PRG
key, it returns
at LEVEL 2 PARAMETERS
without modify value.
REMARK:
If no key is pres-
sed for 25 seconds in either of
the previous steps, the
controller will automatically
return to the CURRENT
TEMPERATURE display status
without modifying any of the
parameters values.
4- Operation
PRG key:
Accepts the alarms and disconnects alarm outputs. When pressed for at least 3 seconds, the SP
SET POINT temperature value is displayed. When pressed for 10 seconds display the first level of menu
SPCF of parameters. Exit programming level.
Key
Q
:
Accepts the alarms and disconnects alarm outputs. In
programming, it makes the displayed value reduce.
Key
N
:
Accepts the alarms and disconnects alarm outputs. In
programming, it makes the displayed value increase.
SET Key:
Accepts the alarms and disconnects alarm outputs.
When pressed during 3 seconds, it activates the Autotune function
if AtEn=1. Deactivates the Autotune function. In programming,
accept the programmed new value.
LED OUT1:
CONTROL 1 indicator activated.
LED AL1:
Alarm 1 indicator enabled. Flashing: Alarm 1 detected, relay deactivated but signalling
maintained.
LED OUT2/AL2:
CONTROL 2 or Alarm 2 indicator enabled. Flashing with Alarm 2: Alarm 2 detected,
relay deactivated but signalling maintained.
LED AT:
Autotune indicator enabled.
4.1 Control 1, control 2 and alarms operation
AUTOTUNE:
Press
SET
key for 3 seconds to activate a SELF-ADJUSTMENT (AUTOTUNE). The controller
will configure automatically the parameters at process characteristics setting.
Gain (GAin):
The output it is configured proportional to the error signal width.
Overall time (ti):
The final error it is eliminated by the output regulation proportionally to the error signal
width and duration.
Derivative time (td):
It determines the controller reaction on process temperature changing. Over and
lower pulses prevention. It is also used to quick actuation on the variable process value in the event of a
sudden change in the set point.
