3. ELECTRIC CONNECTION
CAUTION
When handling electric equipment, take into account the safety standards (EN 60204, Direc. 73/23/EEC).
Check that the type of current, voltage and frequency suits the actuator according to motor nameplate.
When dismounting the electric connection cover, we find, inside this cover, the electric connection
diagram for each actuator.
The IP67 degree of protection, IP68 (on request), is only guaranteed if the correct cable glands are used.
Make sure a proper ground (GND) connection of the unit is done.
CAUTION
Do not attempt to lever off the cover with a screw driver as this will damage the “O” ring seal.
The wiring scheme fixed in the cover is particular to each actuator and must not be interchanged with
any other actuator.
Types of connection :
2- Terminals connection :
a) Feed the cable(s) through the cable glands¹.
b) With a suitable screwdriver, connect the cables for the control signals
according to the electric connection diagram.
c) Connectthe 3 phases L1, L2,L3 to the connections 1,2and 3. Connect
the earth cable to the earth connection.
d) Onceyouhavecheckedthattheconnectionshavebeenproperlycarried
out, close the connection cover and check the proper connection, the
state of the o-ring seal and the proper installation of the latter, greasing
it slightly. Fasten the 4 screws crosswise.
e) Tighten cable glands to ensure enclosure IP67 (IP68 on request).
1- Plug-socket connectors with screws:
a) Unscrew the attachment plate from the connection cover.
b) Feed the cable(s) through the cable glands¹.
c) With a suitable screwdriver, connect the cables for the control signals
according to the electric connection diagram.
d) Connectthe3 phases L1, L2, L3to the connections 1, 2,and3. Connect
the earth cable to the earth connection of the plug.
e) Once you have checked that the connections have been carried out
properly, screw the attachment plate back to the connection over
respecting the direction of the connectors.
f) Close the connection cover and check the proper connection, the state
of the o-ring seal and the proper installation of the latter, greasing it
slightly. Fasten the 4 screws crosswise.
g) Tighten cable glands to ensure enclosure IP67 (IP68 on request).
¹ The cable glands are not supplied with the Standard version.
The modeled curves are:
1 Isopercentage curve
2 Quick opening curve
3 Linear curve
4 Customized curve (example)
will be displayed, then press ,
choose between :
for linear curve
for isopercentage curve
for quick opening curve and
for customized opening curve.
For customized opening, 10 points of alignment ... are displayed, for each of them choose the
corresponding opening percentage between and .
In order to enter the values of the personalized curve, the user should have previously modelized the curve to
know to which opening percentage corresponds each step.
The curve configured as factory standard is .
5.9. ESD (Emergency Shut Down)
In this submenu, the operation of the actuator when receiving the ESD emergency signal, is configured. When
the signal is received, the CENTRONIK will ignore all the securities except the security selection made by the
user, the motor thermoswitches or the torque micro switches.
The goal for the actuator will be to reach the programmed emergency position.
will be displayed, then press .
choose between :
to considerer the thermoswitches or to considerer the torque microswitches.
Next choose between:
for actuator in open position.
for actuator in close position.
for "standstill" position.
ton open the valve up to the recorded proportion. Choose between and .
5.7. Rest time.
In this section, the user can configure the time, in seconds, the actuator will rest after the last stop ignoring any
notice neither from the input remote signal nor from the pushbuttons.
