2.1.2 Electric connection and checking of function
1. Follow instructions in the part "Requirements for professional qualification"!
2. While laying electrical line abide by the instructions for heavy current installations.
3. Cables to terminal boards or connectors lead through cable glands. The cable jacket diameters must
conform to the extent specified in Chapter 1.8.3!
4. Before initiation ES into operation internal and external protection terminals are needed to be
connected.
5. Feeding cables are to be fixed to the solid construction at most 150 mm from the cable glands.
6.
Cables of input controlling signals into a controller and output signals from a converter must be conducted
separately from power conductors or it is possible to use shielded cables.
7. To prevent moisture from entering the actuator around the connecting cables, the cables must be sealed with
silicone material at the point of penetration through device shell.
Connecting with the master system:
The EA can be controlled with:
•
a built-in position controller
•
an external position controller
1. If the EA is controlled with an external controller using unified signal from a two- wire transmitter
(capacitive or resistive with a converter in two-wire connection), it is needed to arrange connecting of
the two-wire transmitter loop to electrical earth of the successive external controller!
2. Connection can be performed only in one point, in any part of loop out of the EA.
3. Electronics of the two-wire transmitters is galvanically insulated that is why it can serve as an
external source for supplying of several transmitters (their number depends on current which the source
can supply).
4. Do not connect and disconnect live connectors !
Notes:
1. Wires of input control signals to controller and output signals from current converter it is necessary to
lead them separately with thrust wires or it is necessary to use shielded wires
2. The EA are delivered with bushings, which in case of tight putting on the leads assure protection
enclosure up to IP 68. For required protection enclosure it is needed to use rings according to the actual
cable diameter.
3. While fixing the cable it is needed to count with allowed bend radius to avoid damaging or deformation of the
sealing element of the bushing. The leads are to be fixed with the solid construction at most 150 mm from
the bushings.
4. It is recommended to use screened cables to connect remote transmitters.
5. The face areas of the control part cover have to be before re-mounting clean, coated with a grease without
any acid (e.g. vaseline) and sealing not damaged to avoid joint corrosion.
6. Reversation of the EA is sure, if the period between switching-off and switching-on of power supply for the
reversed movement of the output part is minimally 50 ms.
7. Delay after switching-off, i.e. time since a reaction of switches till the motor is dead can be maximally 20 ms.
8. It is recommended to have the corresponding direction protection switched-off directly with the
corresponding position or torque switches.
After electric connection it is recommended:
Checking of wiring. Set the actuator into a mid-position. Check the right direction of output shaft
movement with pressing the button "closing" (on a manual control board or on a test button panel) and
the output pointer turn clockwisely looking from above. If not change the order of the mains phases.
Checking of position switches. While the actuator is running in the chosen direction consequently
switch contacts of switches pressing springs of correspondent switches. In case of correct connection
the actuator is to stop. If any of the functions is not correct check the connection in accordance with
the wiring diagram.
In the SPR version with the built-in electronic controller it is needed to perform
autocalibration for assuring optimal functioning.
