1.6 Packaging, transportation, storage and unpacking

EA MO 3.3, MO 3.4 resp. MO 3.5 are supplied in packages, warranting resistance according to
requirements of standards STN EN 60 654.
Package is a box. Products in boxes is possible to load on the pallets (pallet is returnable). On the outer
side of the package is stated:

· manufacturer label,

· name and type of product,

· number of pieces,

· other data – notices and stickers.

The forwarder is obliged to secure packed products, loaded on transportation means, against self­motion; if open transportation means are used, to secure their protection against atmospheric precipitations
and splashing water. Displacement and securing of products in transportation means must provide their
stable position, exclude the possibility of their inter-collision and their collision with the vehicle walls.
Transportation can be executed by heatless and non hermetic spaces of transportation vehicles with
influences within the range:

- temperature: -25° C up to +70° C (a strange version –45 ° C up to +45 ° C

- humidity: 5 up to 100 %, with max. water content 0.028 kg/kg of dry air

- barometric pressure 86 up to 108 kPa

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 pa-lettes), chemicals and
foreign interventions, at ambient temperature from -10°C up to +50°C and at relative air humidity max. 80
%.

Attention!

1. It is not acceptable to store EA outdoors, or in areas not protected against direct climate

influence!

2. It is not recommended to set up the electric actuator manually without mechanic con-nection with
armature. The electric actuator does not have mechanic restriction of wor-king stroke in terminal
positions and therefore can after exceeding of the stroke come to mistuning of parameters set up
by production plant.

3. Eventual damages to surface finish remove without delay – thus preventing damage by corrosion.

4. If storing takes longer than 1 year, it is necessary to inspect lubrication fillings before putting EA
into operation.

5. Assembled EA, but not put into operation is necessary to protect by the equivalent method as
during storage (for example suitable protective cover).

6 MO 3.3, MO 3.4, MO 3.5

6. 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.

7. Excessive preserving grease remove just before putting EA into operation.

1.7 Liquidation of the product and package

The product was made from recycled materials - metal (steel, aluminium, brass, bron-ze, copper, and

cast iron), plastics (PP, PA, POM, PC, PVC) and products from the rubber.
The package and product is necessary after the end of their lifespan to disassembly, to sort their
parts by the type of used material and deliver them to recycling, eventually dis-posing places.
The product, however, contains a mineral oil fill dangerous for the environment.Please avoid oil leak
into the environment at its disposal.

2. Description, function and technical parameters

2.1 Description and function

Electric multispeed actuators MO 3.3, MO 3.4 resp. MO 3.5 consist of these modules:

Module M 1 – electric-motor
Module M11 – countershaft transmission with rotary hold
Module M 3 – force transmission with additional gear box and manual control
Module M 4 – control box

Pic.1

Module M1 – electric-motor

· Three-phase asynchronous electric-motor

Module M11 – countershaft transmission with rotary hold

Countershaft transmission performs reduction of revolutions of electric-motor to speci-fied
transmission value. Countershaft transmission consists of two or three pairs of spur mes-hing toothed
wheels and is terminated by bevel pinion, which meshes into bevel gear of transmission from module M3.
Rotary hold substitutes motor mechanic brake and allows manual control of ES.

MO 3.3, MO 3.4, MO 3.5 7

Modul M 3 – force transmission with manual control (pic. 2)

The set is stored in box (1). Gears are centrally positioned on output shaft (3) and creates independent
assembly unit. Wheel rim (44) with inner gearing provides transfer between electric motor pinion and output
shaft. In upper part is located the warm (2) for moment sensing and manual control, which is used for
positioning of controlled equipment during electric power breakdown. Positioning is executed manually by
handwheel (4). The warm is suspended and a thrust created by output shaft torque axially shifts the warm
against spring tension. The warm movement is transfered by the fork with pin through a shaft (45) joined to
control box. Movement of the warm is proportional to the moment.
The fork meshes into circumferential notch, allowing rotary motion of manual wheel, therefore manual
control in every operating status. On the box (1), (across to manual wheel) are three bosses with threaded
openings allowing assembly of electric actuator on the wall, or supporting construction.

Pic. 2

Module M 4 – control box (pic. 1)

Control box is in upper part of electric actuator and forms individual function unit. The top part is
formed by the cover with opening and monitoring window of position indicator.
The bottom part of control box closes the box of force transmission and forms carrying part of control
plate pic.3, 4

On mounting base (46) of control plate are fixed these functional blocks:

· position-signaling unit (11)

· transmission unit (8)

· heating resistor (16)

· torque unit (9)

· transmitter unit (33)

· electric connection via terminal boards (58), located in control compartment and cable bushings

(7), respectively connector with cable bushings.

· module of local electric control (pic. 14) is interconnected with control plate

pic. 3 – control board with resistive transmitter

pic.4 – control board with converter

MO 3.3, MO 3.4, MO 3.5 9

Transmission unit (pic.5)

Transmission unit is designed as individual
assembly unit. It is composed by multiple
reduction. Into mesh is connected via input
toothed wheel (12). The output is made of too­thed double gear (14), pic.3, 4 for the drive of
position and signaling unit and the eccentric (15)
for transmitter unit, on which is transformed the
motion from the gearbox eccentric (15) through
lever mechanism (27), (28), to rack-type drive (30)
pic.3, (31) of transmitter (10), pic. 7.
The output of transmission unit is three­stage. Individual gears are shifted into mesh by
shifting toothed wheel (43), which is fastened onto
output shaft (48) by a pin (50).
Pic. 5

Position-signaling unit (11) (pic. 3, 4).
Position-signaling unit provides turn-off of switches S4 or S3 after reaching preset revo-lutions of

output shaft and transmission of electric signal for
purposes of signaling position of electric actuator
output shaft. Rotary motion of the unit is derived
from output shaft through transmission unit to input
wheel (32) pic. 6. This wheel turns the shaft, on
which are located the cams. Turning of the cam
onto trip dog (36) of micro-switch S3, S4, S5, S6
(37, 38, 39, 40) will cause switch over of micro­switch.
The cams (53), (54), (56), (57) can be turned
after releasing of locking nut (51) and a nut of
position-signaling unit (65). The construction of
position unit is designed in a way, that during
adjustment of one cam will other cams remain
without motion. After adjusting of posi-tion unit must
be the nut (65) and locking nut (51) fastened.

Pic. 6

Transmitter unit (33) (pic.3).
This unit serves for creation of a signal, which magnitude corresponds to actual posi-tion of
electric actuator. The basic element of the unit is
resistive transmitter (10), pic. 7, with the nominal
value of resistive signal 100W.
The transmitter drive is created by the slide
(27), pic. 3, on which is transferred the motion from
eccentric (15) of transmission unit, by the lever (28),
at the end of which is atta-ched rack-type rod (30)
and by shifting pivot (29). The positions of shifting
pivot (29) then determines the ratio of shifting gear
mechanism, i.e. for various values of electric actuator
working revolutions is the transmitter wheel angle
always 160°. This allows availability of the transmitter
signal nominal value to be (100W) for working
revolutions.
Pic. 7

10 MO 3.3, MO 3.4, MO 3.5

Torque unit (pic. 8) consists of two function units:

· torque disk (pic. 8)

· torque unit (pic. 9) with locking mechanism (82)

Torque disk (pic. 8) is connected to torque
shaft (45) discharged from force trans-mission
(pic.2). The torque disk turn angle is proportional to
torque of output shaft (3) of elec-tric actuator. Its
magnitude is adjustable by set up of segments (17)
and by shifting of back-stops (18). Achieved torque
value is from torque disk transferred to torque unit
(pic.9) via tor-que lever (42).

Pic.8

Remark:
The marks on the scales determine the range of turn-off torque (min. and max. value for given
make), within which can the torque magnitude be adjusted, the value of turn-off torque is not implicitly
stated, during set up serve only for more accurate orientation about its magnitude without testing
device for torque measurement.

Torque unit (pic.9) is created by a console with switches

S1 (20) and S2 (21). On the shaft (23) are located turn-off
levers (24), which by the spring force keep switches
contacted until the moment when the shaft from torque
turn-off drive will be turned.

Locking mechanism (82) (pic.3, 9) provides locking of
torque turn-off usually at 1 or 2 revolu-tions after reversing
of electric actuator. Torque unit will gain its original
function after elap-sing of set up revolutions.

Pic. 9

Heating resistor

The electric actuator is provided by heating resistor (16) (pic. 3 respectively 4) with total output
20 W. The connection of heating resistor is dependent on working environment (see art. 1.5.1).

Electric connection

Electric connection can be performed via terminal board (58) (pic.3, 4) or connector.

3. Assembly and disassembly of EA

Adhere to safety rules!

Notes:

Repeatedly verify whether placing of EA correspondents to part "Operating conditions". If actual
conditions differ from recommended, it is necessary to consult it with manufacturer.

Before commencing of EA assembly to the armature :

· Repeatedly verify, if EA was not damaged during storing.

· According to data label verify conformity between working stroke set up by manufacturer and EA

connecting dimensions with parameters of armature.

· In case of discrepancy perform set up according to part “Set up“.

3.1 Assembly

The actuator is set up by the manufacturer to the parameters according to label tag, with
connecting dimensions according to relevant dimensional drawing and is set to half-position.
Put on the handwheel before assembly.

3.1.1 Mechanical connection to the armature

In case that required shape of mechanical connection is designed by A-shape adap-ter (with
flange F16 resp. F14), at first is necessary to fix this adapter to connecting flange of EA by the screws.

Mechanical connection – shape of connecting element B, C, D and gear clutch (see dimensional
drawings):

· Bearing surfaces of EA connecting flange must be carefully de-greased.

· Slightly grease the output shaft of armature.

· Shift EA to its terminal position „CLOSED“; shift armature into identical terminal position.

· Put EA on armature, so as output shaft reliably fits into clutch of armature.

Warning!
Do not use force when you put EA on armature, otherwise the gear can be damaged!

· Should there is the necessity to synchronize the openings in the EA flange and armature, turn the EA

by hand wheel;

· Verify, whether connecting flange fits tightly to the armature / gearbox.

· Attach the flange by four bolts (with mechanical hardness min. 8G), which steadily tighten

crosswise.

· At the end of mechanical connection perform the check of proper connection with the

armature, by turning hand wheel to direction „open“.

Mechanical connection – rising spindle (for shape A resp. C, eventually B3):

· If the rising spindle of armature is in terminal position „open“ longer than dimension from fastening

flange up to the cover above shaft of additional gearbox, disassembly the cover of output shaft on
the box of additional gearbox and replace it after assembly of electric actuator on armature by
covering pipe (it is not a part of delivery).

· Seating surfaces of EA connecting flange and armature carefully de-grease.

· Slightly grease the output shaft of armature.

· Shift EA to terminal position „CLOSED“; shift armature into identical terminal position.

· Slide electric actuator by output shaft / nut on the spindle / nut of armature and turn by hand wheel

counterclockwise until connecting flange of electric actuator fits to connecting flange of armature.
Further procedure is identical to previous part of mechanical connec-tion for shapes B, C, D.

· At the end of mechanical connection perform the check of proper connection of EA with the

armature by tur-ning the hand control wheel to direction „open“...

Remark:

EA can be also attached to the wall construction via three bosses located on outer wall of the
box across to hand wheel.

MO 3.3, MO 3.4, MO 3.5 15

3.1.2 Electric connection to the network, respectively control system

Consequently perform electric connection to the network, respectively to joining system.

1. Adhere to instructions stated in chapter 1.2 Safety instructions – Requirements for professional

skills....

!

4. Before putting the electric actuator into operation is necessary to connect inner and outer groun-ding
terminal.

5. Leading-in cables must be attached to firm construction maximum 150 mm from bushings!

6. The bushing blinds are for transportation and storing purposes only. Should one of cable bushings is not
used, this bushing must be secured by the blinder.

Electric connection to the terminal board:

Before electric connection remove the cover of electric actuator control box and check whether the

type of electric current, supply voltage and frequency comply with data on electric motor type label.
Electric connection:

· Perform electric connection according to connection drawing, which is glued in EA cover.

· Electric connection is performed by two cable bushings.

· Put the cover on and fasten it steadily crosswise by bolts. Firmly fasten cable bushings to secure

coverage.

Electric connection to connector

· Check, whether the type of electric current, supply voltage and frequency comply with data on
electric motor type label

· Release bodies of the connectors

· Strip the ends of wires

· Attach relevant connector tubes to the wire ends by means of pliers.

· Slide the tubes into relevant contacts of connector according to connection drawings.

· Fasten and tighten connectors.

· Firmly tighten cable bushings to secure coverage.

Remarks:

1. Stuffing bushings are delivered with EA, which in case of tight mounting on supply line secure co-verage up
to IP 68. For required coverage is necessary to use ringlets according to actual cable diameter and required
thermal resistibility.

2. During attachment of a cable is necessary to watch acceptable bending radius to prevent damage,
respectively not acceptable deformation of sealing element of cable bushing. Supply cables must be
attached to firm construction maximum 150 mm from bushings.

3. For connection of remote transmitters is recommended to use shielded wires.

4. Sealing surfaces of control part cover must be cleaned before repeated fastening.

5. EA reversal is secured, if time interval between switching OFF and ON of supply voltage for rever-se
direction of output part motion is minimum 50 ms.

6. Delay after turn-off, i.e. time from reaction of the switches until the motor is without voltage, can be max.
20 ms.

After electric connection perform the functional check:
The check of el. motor connection and control drawing. Set up the electric actuator by hand
wheel to half position. Check proper connection by pressing the pushbutton "close" (on the box of
manual control, respectively on the panel of testing pushbutton box) and output shaft must turn
clockwise from the view from the top view (into control box) on output shaft. If it is not so, change the
sequence of electric power network phases.
Check of torque switches (pic.9). When the actuator moves towards "close" and at torque
switches connection to "torque switching-off" should be contacts of switch S2 (21) switched over by
pressing of disconnecting bell of relevant switch. If the connection is properly performed, the actuator
must stop. When the torque switches are connected for "signalization" only, signalization on control
box pannel will be activated.

2. During deposition of electric line is necessary to adhere to regulations for installations of heavy­current equipment.

3. Line wires to terminal boards, respectively to connector lead by screw cable bushings.

Adhere to instructions of armature manufacturers, whether turn-off in terminal posi-tions
must be executed via position, or force switches!

16 MO 3.3, MO 3.4, MO 3.5

Analogous repeat test towards "open" by switching over of switch S1 contacts. If any of

function is not correct, check the connection of switches according to wiring diagram.

Check of position switches (pic.7). When the actuator moves towards "close" switch over
contacts of switches S4 (39) resp. S6 (40) by pressing of disconnecting bell (36) of relevant switch. If
the connection is properly performed, the actuator must stop when contacts of switch S4 are switched
over and light up when contacts of switch S6 are switched over. Analogous repeat test towards
"open". By pressing disconnecting bell of switches S3 (37) resp. S5 (38), the actuator must stop resp.
signalize. Again, if any of the function is not correct, connection of switches should be checked
according to wiring diagram.

3.2 Disassembly

Attention!
Before disassembly is necessary to disconnect electric supply of electric actuator!

!

potential electrical accident!

· Turn off EA from power supply.

· Disconnect connecting wires from terminal board of EA and release the cable from bushing. In

version with connector is enough to disconnect the connector.

· Release fixing flange bolts and EA coupling bolts and separate EA from the armature.

· If you will send EA to the service, pack it to sufficiently firm package, to prevent its damage during

transportation.

Connection and disconnection of connectors must not be performed under the vol-tage!
Secure by prescribed way protection against connection of EA to the network and thus

MO 3.3, MO 3.4, MO 3.5 17

4. Set up

Attention! See article 1.2.
Switch OFF the electric actuator from electric power line!

!

EA is from production plant set up to fixed value of working revolutions S (stated by customer
in the order). If you want to set up EA to other parameters, proceed according to following instructions.
Set up is performed on mechanically and electrically connected electric actuator. In this chapter is
described set up of electric actuator to parameters specified in specification table in case if you need
to change preset parameters of electric actuator. Displacement of adjusting elements of control board
is in pic. 3, respectively in pic. 4.

4.1 Set up of transmission unit (pic. 5)

4.1.1 Stage set up

Individual stages are geared into mesh by shifting toothed wheel (43), which is faste-ned onto
output shaft (48) by the pin (50). After adjustment of required stage and securing of shifting wheel is
put on the upper front of a gearbox (49) with input wheel (12) and is secured by locking washers (47).

Pic. 10

4.1.2 Set up of subscale

Adhere to safety regulations!

The gearbox of transmission unit is necessary to adjust into two stages (see table 2).

For set up of relevant subscale according to Table 2 is used the magnitude of curve rising “a“
(short curve), respectively “b“ (long curve).

Table 2

Type II. stage III. stage
curve a b a b

stroke – working
revolutions

MO 3.3 1 – 3 3 – 12 15 - 38 38 - 115
MO 3.4 1 – 4,5 4,5 – 16,5 21 – 53,5 53,5 - 160
MO 3.5 1 - 3 3 - 11 14 – 34,5 34,5 - 100

The growth of circulant based on the angle, must be clockwise from the sight of eccen-tric.
Should set up curve is unsufficient; unscrew the nuts (41) pic. 3, respectively pic. 4, thus allowing
access to gearbox fastening bolts, remove securing ringlet (52) pic.5 and washer (61) and eccentric
(15) turn the other side. During repeated securing by securing ringlet you will have to overcome the
force of flat spring, which in connection with other parts forms friction securing clutch of transmission
unit.

Example:

EA MO 3.5 with 10 working revolutions (II. stage, curve “b“) should be set up to stroke of 15 working
revolutions (III. stage, curve “a“).

18 MO 3.3, MO 3.4, MO 3.5

Change of the stage:

· Shift shifting toothed wheel (43) to III. stage according to chapter 4.1.1

Change of subscale – curve:

· Insert eccentric (15) in a way, that the growth of circulant is on the curve “a“ (short curve).

· Insert the washer below eccentric and secure against extension by shaft securing ringlet.

· During repeated insertion of transmission unit into control box must be the cam reset in a way that

its mesh with the pin of slide control (27) is in lowest point. During insertion of transmission unit
must the shaft (48) pass through the openings of slide control (27) and mounting base (46).

4.2 Set up of position-signaling unit (pic.6)

EA is by production plant set up to fixed number of working revolutions stated on type label of electric
actuator. During electric actuator adjustments proceed as follows:

§ Release nuts (51, 65) securing cams to the extent, that disk springs will still produce axial

pressure on them,

· Reset electric actuator to position "open" and turn by cam (57) clockwise, until switch S3 (37) will

switch over,

· Reset electric actuator through the angle, in which should signalize position "open" and turn by

cam (54) clockwise until switch S5 (38) will switch over,

· Reset electric actuator to position "closed" and turn by cam (56) counterclockwise until switch S4

(39) will switch over,

· Reset electric actuator back through the angle, in which should signalize the position "closed" and

turn by cam (53) counterclockwise, until switch S6 (40) will switch over,

· After set up of electric actuator secure cams by central ribbed nut and back nut (51, 65).

· The cams for signaling are, until otherwise agreed, set up just in front of terminal posi-tions. The

possibility of signalization is throughout whole working angle in both directions, i.e. 100 %.

4.3 Set up of resistive transmitter

Reset EA to position “closed“. Turn the toothed disk (13) (pic.4, 5) clockwise by screw-driver.
Thus will be achieved turning of eccentric (15), along the curve of which is shif-ted the backstop of the
shifter (27) (pic.3). The motion is out of it transferred on the le-ver (28). Turn by disk and eccentric until
the lever (28) is parallel to the cut-out of con-trol plate, in which is moving shifting pin (29) and the
transmitter will indicate turning to “Z“(160°). Now is the transmitter set up for position “closed“.
Consequently reset EA to position “open“, while the needle of the transmitter is set up to position
between “O“ and “Z“. Release the nut securing shifting pin (29). Adjust it towards transmitter until the
needle of resistive transmitter (10) indicates to “O“(0°). Secure shifting pin in this position by nut and
check working range of set up and values of resistance in terminal positions.

During this set up is necessary to preserve original adjustment of spring (59) (pic.7). In case the
clutch of transmission unit will slip, it is necessary to release the pre-stress of transmitter by releasing
the spring (59).

Attention:

The backstop of shifter (27) must not during turning of eccentric (15) pass through the top of eccentric. In
that case would the sense of resistive transmitter rotation be reversed and the range of transmission unit set up
would be changed, in connection with transition from one eccentric curve to another.

Set up of torque unit can be performed only in connection with device for measurement of torque
moment and only within relevant scope, according to table of makes, by rough regulation (17) and soft
regulation (18), pic.3 respectively pic. 4.
Set up of turn-off torque moment by segments (17), pic.8, can be performed only within scope of
interval MIN – MAX highlighted torque moment disk within relevant torque moment scope of electric
actuator.
For the change of torque moment range is necessary to replace springs in torque mo-ment
drive, what can be, due to assembly demands, only in production plant, respectively service center.

4.7 Set up of locking

5. Service, maintenance and troubleshooting

5.1 Service

1. In general it is provided that service of the EA is performed by a qualified worker in accordance with
requirement given in Chapter 1!

!

2. After putting the EA into operation it is needed to verify whether during manipulation any scratch on

surface occurred, it is to be removed to prevent actuator against corrosion!

· Electric actuator requires only inconsiderable operation. The assumption for reliable ope-ration is

proper putting into operation.

· Operation of multispeed EA results from operating conditions and usually is limited to pas-sing of

impulses to individual functional tasks.

· In case of electric power breakdown perform set up of controlled body by hand wheel.

· If is electric actuator connected to the circuit f automatics, it is recommended to place members for

manual remote control in the circuit, in order to control electric actuator even during breakdown of
automatics.

· The operators must take care for performing of prescribed maintenance and for protec-tion of EA

during operation against harmful ambient effects and atmospheric exposure, which exceeds the
scope of acceptable effects described in part „Working conditions“.

· The operation above the scope of turn-off torque moments is not permitted.

· It is necessary to prevent excessive heating of the surface of EA, exceeding of type label values

and excessive vibration of EA.

5.2 Maintenance – scope and regularity

During inspections and maintenance is necessary to fasten every bolts and nuts, which effects
tightness and coverage.
Exchange oil after 500 hours of actuator´s operation. Chesk oil every quater of year. The oil level
is to reach the fillng hole. The actuator is to be filled with the gear oil .To fill the actuator up is needed
1,6 l of the oil. Once a half of year it is needed to rub teeth of gearing of the control box and bearings
where the gearings are set.

Lubrication:

· the gearbox – oil 80, or Gyrol 75W

· gears of transmission unit and drive mechanism on the control board – grease Gleit-μHF 401/0

Lubrication of armature spindle is performed regardless on EA service!

· It is recommended to perform inspection run every 6 months within set up working stroke

to verify proper function, with reverse set up of original position.

· Unless otherwise stated in revision rules, perform inspection of EA once a year, whereby check

tightening of all connecting and grounding bolts, to prevent heat-up.

· 6 months after putting EA into operation and then once a year is recommended to check tightness

of fastening bolts between EA and armature (bolts should be tightened by cross method).

5.3 Troubleshooting

At failure of power supply the EA stops in the position where it was before the failure. If needed the

EA can be set only with the manual control (the hand wheel). After restoration of power the EA is prepared
for operation.
In case of failure of any element of the EA it can be changed by a new one. Entrust the change to a
service centre.

In case of an EA failure, which cannot be eliminated directly in operation, follow instructions for

under-guaranty and after-guaranty service.

Note: If the EA requires dismantling follow the chapter "Dismantling".

!

Taking the EA to pieces for repair purposes is allowed only by professionally qualified
persons trained in the production plant or by a contracted service centre!
