Upon receiving of EA examine, if during transportation, resp. storing did not come to its
damage. At the same time verify, if the data on the labels corresponds to accompanying
documentation and purchase-sale contract / order. Eventual discrepancies, faults and damages
should be reported without any delay to supplier.
Electric actuators and their accessories must be stored in dry, well ventilated covered spaces,
protected against impurities, dust, soil humidity (by placement to racks, or on palettes), chemicals
and foreign interventions, at ambient temperature from -10°C up to +50
°
C and at relative air
humidity max. 80 %.
It is not acceptable to store EA outdoors, or in areas not protected against direct climate
influence!
Eventual damages to surface finish remove without delay – thus preventing damage by corrosion.
If storing takes longer than 1 year, it is necessary to inspect lubrication fillings before putting EA
into operation.
Assembled EA, but not put into operation is necessary to protect by the equivalent method as
during storage (for example suitable protective cover).
After assembly to the armature in free and wet areas, or in areas with temperature changes,
connect without delay heating resistor – thus preventing damages caused by corrosion from liquefied
water in the control area.
Excessive preserving grease remove just before putting EA into operation.
1.7 Assessment of the product and packaging and removal of contamination
The product and its package are made of recycling materials. Do not throw the single parts of
the package and of the product after their life but sort them according to instructions in corresponding
executives or regulations of environment protection, and allow their recycling.
The product and its packing are not a source of any environment pollution or contamination and
do not contain any dangerous waste.
2. Description, function and technical parameters
2.1 Description and function
The
SP and SPR
EA consist of two parts differing in their function.
The
gear part
is made up by a flange and a connected part for connection onto a controlled
device, and gears placed in the bottom; on the other side drive mechanisms for control part units are
surfaced.
The
control part (Fig. 3)
is placed on a control board (2) consisting of:
•
an electric motor (at single-phase version with capacitor)
•
a torque unit (controlled with a worm axial shift)
•
a position-signaling unit with (3) a position transmitter (5) - positioner (resistive - potentiometer,
capacitive or an electronic position transmitter) and with a mechanical local position indicator
•
a space heater with a thermal switch (8)
•
electric connection is realised using
terminal boards
(6) (located in the control area) and cable
cable glands (12) , or
connector
with cable cable glands.
Additional accessories:
Manual control:
made up by a handwheel with a worm gearing.
Local electric control module
(Fig.11).
The
SPR
version is equipped with an
electronic controller
. The position controller allows automatic
position adjustment of the EA output part depending upon the input signal value and provides also
additional functions.
