Technical Features
Technical characteristics of Valbia electric actuators as below:
•
Heater: all actuators are standard equipped with heater to avoid
condensation into the actuator (paragraph 6.4);
•
A safety system detects when the actuator supplies a torque
higher than expected (torque limiter): the device makes three
triggering attempts. In case of negative results, it makes a short
rotation in the opposite direction to relieve the mechanical ten
sion to the gears. The torque limiter intervention is] indicated by
a red color LED (paragraph 6.5) and by the opening of the re
mote signal an auxiliary contact (paragraph 6.2).
•
A safety system intervenes to shut off the actuator in case the
motor works past over the allowable operation time value (the
time value depends on the actuator models). The maximum
working time fault is indicated by a red color LED (paragraph
6.5) by the opening of the auxiliary contact of the remote signal
(paragraph 6.2).
•
Duty rating: the electric actuator was designed to work with
a nominal duty rating of 75% (or 50% in the 12V ac/dc models),
referred to the working time, the maximum temperature and to
the nominal load. This parameter defines the rest time after an
operation. The use of the actuator with an higher duty rating
or with a temperature above 55°C (131°F) can cause the im
proper torque limiter intervention or the failure of electronic com
ponents.

1. Remove position indicator “B” by loosening the screws “C”;
2. Screw the fasteners “D” to remove the upper cover “A”;
3. Raise up the cover “A” carefully to avoid to damage the internal
electric parts;
4. Turn in the electric supply cable (diameter 6 ÷ 9
mm / 0.24” ÷ 0.35”) by the properly bolds “E” (PG11);
5. Proceed to connect the cable in its proper terminal block “F” by
looking at the wiring diagram (Fig.2) according to the different
voltage (please also review the tag you find inside the cover).
WARNING: the actuators should be properly grounded and wired in
accordance with local electrical code.
WARNING: before performing any maintenance on the actuator, al-
ways make sure to shut off the power supply first.
WARNING: make sure that the power supply is set between the val-
ues indicated as indicated on the label on the side of the actuator.
WARNING: Valbia electric actuators may be mounted in many po-
sitions, however, we do not suggest using it with the cable glands
positioned upright, since it cannot guarantee a perfect wiring tight-
ness. We also recommend to avoid using it with the indicator facing
down. If the actuator assembly and the respective electrical con-
nection are provided in different moments, make sure that the cable
entries are hermetically sealed.
WARNING: please ensure suitably rated cable glands and protec-
tion plug are used, according to IP protection rating. Properly seal
the electrical connectors to prevent any liquid and dust infiltration.
Warranty is voided if this warning is not respected.
The cables must be of the appropriate size to the type of electrical
connector selected. Verify the correct tightening of the electrical con-
nectors.
WARNING: if the device is used not respecting the manufacturer
specifications, the provided protection may be impaired. For the wir
-
ing, it is necessary to open the upper cover “A” in order to locate the
terminal block on the power supply board.
