Electric actuators may be installed and operated in enclosed locations of industrial facilities with
no temperature and moisture regulation, protected from direct climatic effects (such as direct sunlight).
Moreover, special “marine” versions may be used in waste water treatment applications, water
management, selected chemical applications, tropical environments and coastal areas.
EA have to be placed with the view of access toward handle of manual operating, top cover and
bushing. Installation and operation of EA is possible in any position.

Warning:
When the EA is installed in open air, it must be sheltered lightly to protect is against direct

!

effects of atmosphere.
When installed in the areas with relative humidity more than 80%, in open air under a
shelter is needed to connect the space heater directly – without a thermal switch.

1.7 Description

The ST electric actuators are designed for automotive position control of linear valves where
relatively small control thrust is
required. They can be also used in
air-conditioning, heating as well as
in technological systems.
The actuators are driven with
an electric motor (1) fed and
controlled through two thrust
switches (2). The thrust switches
are switched with a finger (5). The
position switches are switched with
motion of the cams (4).
The actuators are controlled
with connection of voltage to the
corresponding actuator terminals. If
the voltage is connected to the
terminals 1 and 12 of the two­thrusts version (the thrust switches
S1 and S2), or 1 and 20 ones in
case of the one-thrust version (the
position switch S3 and the thrust
switch S2), the actuator output part
performs linear motion in the
direction „opening“. The motion in the direction „closing“ can be reached with connection of voltage to
the terminals 1 and 16.
In accordance with the order the control part can also contain a position transmitter (6) (resistive
or with the unified current or voltage output signal) functioning as a feedback or as a remote position
transmitter. The remote position transmitter with the unified output signal consists of the 2000 Ω
resistive transmitter and the electronics board. The transmitter rotation is derived from the output shaft
through the gear wheels system (7).
In case of mains failure or switches damages the actuator can be operated manually following

the instructions given in the chapter 4. Service... .

The STR version is equipped with an electronic controller.

shelves or onto pallets), chemical impacts and encroachment, at ambient temperature from

-10°C up to +50 °C and relative humidity max. 80 %.

It is not allowed to store EA in the open air or in areas not protected against direct impact of
climate!
If any scratch on the surface finishing occurs remove it immediately - you protect this way
actuators against damaging with 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.

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. It is recommended to use screened cables to connect remote transmitters.

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.

ST 0, STR 0 15

Connecting with the master system:

The EA can be controlled with:

• a built-in position controller

• an external position controller

The actuator is connected in accordance with the wiring diagrams put into the actuator upper
cover. Electric connection is made through cable glands to the terminal boards. The terminal board
with six terminals (9) (Fig. 1) is designed for connection and control of the actuator and the terminal
board with three terminals (10) for connection of the transmitter. The installed set of capacitors (8)
allows starting of the actuator.

After electric connection it is recommended:
Check of wiring of the electric motor and the control part: Set the actuator into a mid-position.
Check the right direction of output shaft movement with pressing of the button „closing“ (on the manual
control box or on the test press-button box), and follow the output stem which should shift out from the
actuator. If not you check proper connection.
Check of the position switch: When the actuator is moving in the direction „opening“ switch the
contact of the switch with pressing of its switching spring. In case of proper connection the actuator
should stop. If any of the functions is not proper, check wiring of the switches in accordance with the
wiring diagram.

In the STR version with the built-in electronic controller it is needed to perform autocalibration for
assuring optimal functioning.

!

The procedure is as follows
Press the button SW1 for about 2 sec (i.e. till the D3 diode is got on) to set the controller to the

autocalibration mode. During this process the controller checks the feedback transmitter and the

sense of turning, puts the EA to the positions open and closed, measures inertia mass in the directions
"opening" and "closing", and loads the adjusted parameters into the EEPROM memory. In case that
during the initialisation process an error occurs (e.g. in connection or adjustment) the initialisation
process will be interrupted and the controller with the D4 diode reports about the type of the error. Else
after finishing the initialisation process the controller is put into the regulation mode. If needed to
change adjusted parameters of the controller follow instructions given in the part Adjusting of actuator.

2.2 Dismantling

Before dismantling it is required to disconnect the EA from mains!

!

Do not connect and disconnect live connectors!

• Disconnect the EA from mains phases.

• Disconnect the leads from the EA terminal boards and loosen the cables from cable glands.

• Loosen the fixing screws of the EA flange and of the coupling and disconnect the EA from the valve.

• While sending the EA to be repaired put it into a package solid enough to avoid damages of the EA

during transportation.

3. Adjusting of actuator

Abide by safety measures!

!

The adjustment can be performed at a mechanically and electrically connected EA. This part
describes adjustment of EA to specified parameters in case that any unit of EA is reset.
Laying of adjusters of the control board is shown on Fig.1.

16 ST 0, STR 0

3.1 Gear unit adjustment

The switching thrust values both for the direction „opening“ (the thrust switch S1) and for the
direction „closing“ (the thrust switch S2) are in the production plant adjusted to the rated thrust with
tolerance ±10%. The numeric values are given in the corresponding specification table. Adjustment
and resetting of the gear unit to other thrust values are not possible without having a special test
device to measure thrust values.

3.2 Position unit adjustment (Fig. 6)

The position switches are to be adjusted with setting the cams switching them. Turning the cam
is performed with a screwdriver put into the cam groove.

Adjustment of the S3 limit switch

In case of the one-thrust wiring of the actuator the electric motor is during the actuator motion in
the direction „opening“ fed through the S3 position switch. If it is out of tune follow these steps:

• Put the actuator and the controlled device to the required position „open“.

• Turn the cam switching the switch S3 clockwisely until the switch S3 switches.

Adjustment of the additional position switches

The switches are in the plant adjusted to switching ca. 1mm before the correspondent limit
position of the actuator.

While adjusting of the switches S5 and S6 follow these steps:

• Put the actuator to the position where the switch S5

should indicate the position „open“.

• Turn the cam switching the switch S5 clockwisely until

the switch S3 (14) switches.

• Put the actuator to the position where the switch S6

should indicate the position „closed“.

• Turn the cam switching the switch S6 counter

clockwisely until the switch S6 switches.

S3 – position switch "open"
S5 – additional position switch "open"
S6 – additional position switch "closed"
Fig.6

3.3 Adjustment of resistant transmitter

The resistant transmitter is in the EA ST used to function as a remote position indicator; in the

EA STR to function as a feedback in the position controller and if needed also in the position of a
remote resistant position indicator.
The potentiometer is not needed to be adjusted, it is able to adjust itself with putting the actuator
to the both limit positions in accordance with the stroke specified on the nameplate.

Notes:

1. If the actuator was adjusted to another stroke the transmitter resistance in the limit positions should not

correspond with the technical parameters given in the chapter 1.7.

2. In case that the EA is not used in the whole stroke range given on the nameplate, the resistance in the limit

position "open" is proportionally reduced.

3. In the EA STR 2000Ω resistant transmitters are used. In the other cases if the resistant branch is lead to the

terminal board the resistance of the transmitters is according to the customer's specification.

nameplate. At values less than 85% the value of the output
signal is reduced proportionally.

3.5 Adjustment of position controller (Fig. 9)

The built-in position controller REGADA of new
generation is a user-friendly control system to control
actuators with an analogue signal. The controller takes
advantages of high-power RISC processor MICROCHIP to
perform all functions. It provides also continuous
automotive diagnostics of the system, error messages as
well as number of relay switching and number of
controller's operation hours. Placing an analogue signal
onto the input terminals of the terminal board 86/87 (GND,

-) and 88 (+) causes that the EA output is reset.
Required parameters and functions can be programmed using function buttons SW1 - SW2 and
LED diodes D3 - D4 placed directly on the controller, see Table 2.

3.5.1 Setting of controller

The controller's microprocessor unit is in the production plant programmed to parameters given
in Table 2 (Note 2).
Setting of the controller is performed using buttons and LED diodes.
Adjust the position and thrust switches and the position transmitter before adjustment of the
controller.

Controller setting procedure:

The initialisation routine starts at the switched-on controller, zero system deviation and short pressing
of the SW1 button for ca 2 sec (i.e. until the diode D3 got on). Loosing the button some of the default
menus starts (usually control signal) what is shown with 1 blink on the D3 diode as well as one of the
default parameters (usually control signal of 4-20mA) what is shown with 1 blink on the D4 diode.
Then the required parameters of the controller can be changed according to Table 2:

• press shortly the SW1 button to list the menu shown with the blinking number on the D4 diode.

• press shortly the SW2 button to set parameters shown with the blinking number on the D4 diode.

After changing of the parameters according to user's wishes, put the controller to autocalibration
with pressing the SW1 button for ca 2 sec (i.e. until the diode D3 got on). During this process the
controller performs the feedback transmitter and turning sense checking, sets actuator to the positions
"open" and "closed", measures inertia mass in the directions "opening" and "closing", and loads the
adjusted parameters into the EEPROM memory. In case that during the initialisation process an error
occurs (e.g. in connection or adjustment) the initialisation process will be interrupted and the controller
with the D4 diode reports about the type of the error. Else after finishing the initialisation process the
controller is put into the regulation mode.

Error messages of the controller with D4 diode at initialisation

4 blinks.......... improper connection of the thrust switches

5 blinks.......... improper connection of the feedback transmitter

8 blinks.......... bad sense of actuator's turning direction or adverse connection of the feedback

4.1 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!

The EA ST/STR requires just negligible service. Proper putting into operation is a recondition of
reliable operation.
The service of the EA leads from the operation conditions and usually resides in information
processing for further arranging of required functions.
The stuff has to perform prescribed maintenance to prevent the EA during operation against
impacts of environment, which exceed the frame of allowed influences.

22 ST 0, STR 0

Manual control:

If needed (during adjusting, function checking, failure etc.) the stuff can change setting of the
controlled body using the handle.

Instructions for manual control:

• Switch the power supply off.

• Turn the button for gear disengagement to the right by 90° (Fig. 10, the button arrow shows the

symbol of hand) what disengages the gear in the actuator.

• Set the actuator to the chosen position:

• Push and turn the hand wheel located on the actuator upper cover. While

turning counter-clockwisely the valve is turning in the direction "open".
Having the valve in the required position turn the button for gear
disengagement to the position "motored operation" what engages the
gears. Put the hand wheel back to its original position.

Note:
After putting the button for disengaging of gearing again to the position of motor
operation if the gearing is not connected it is needed to turn the hand wheel to put the
gears into mesh.

In case of manual control the set of end positions are not detuned.

Fig. 10

4.2 Maintenance - extent and periodicity

All screws and nuts affecting tightness and protection (IP) must be tighten during the inspection
and maintenance. Similarly, once a year should be checked and if necessary tighten mounting screws
of the terminal wires and assuring of the slip-on joints with wires.

The internal between two preventive inspections is four years.

In case of damage or after 6 years of the actuator´s operation the replacement of cover seals
and oil filling seals must be done.

The grease in the supplied actuators is designed for the lifetime of the product.
It is not necessary to change the grease during the operation of the actuator.

Lubrication:

• - gear part – grease HF 401/0 (GLEIT-µ) resp. GLEITMO 585 K

• - linear adapter – grease GLEIT- µ - HP 520M.

Lubrication of the valve stem is independent on maintenance of the EA!

After every potential flooding of the product check, whether there is no water inside. After eventual
water penetration, dry the product before repeated putting into operation and replace damaged
sealings, resp. other parts of EA. identically check also tightness of cable bushings and replace them,
if they are damaged.

• Every six months it is recommended to perform one check move in frame of adjusted operation

stroke to verify reliability of functioning with setting back to the original position.

• If the audit rules do not determine else the inspection of EA is performed ones a year and

tightening of all connecting and grounded screws have to be checked to avoid overheating.

• After 6 months from putting of EA into operation and once a year it is recommended to check

tightening of fixing screws between the EA and the valve. (Tighten the screws with the cross
system.)

• While connecting and disconnecting of the EA check the tightness of cable glands –
those with damaged sealings should be replaced by new ones of the approved type!

• Keep the EA clean and take care about removing impurities and dust. The cleaning has
to be performed regularly according to the operation possibilities and requirements.

ST 0, STR 0 23

4.3 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 handle). 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.
For controller repair a F1,6 A subminiature fuse for PCB should be used, alternativelly also F 2A, 250

V e.g. Siba type 164 050.1,6 or MSF 250, and for DB .... voltage source repair a M160 mA, 250V

fuse, e.g. Siba, or MSF 250.

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!
