1.5.1 Lifetime of actuators

The lifetime of an electric actuator (EA) is at least 6 years.
EA used for closing mode (closing valves) comply with the requirements for at least 15,000 working cycles
(cycle C – O – C: for linear EA).
EA used for regulating/modulating operation (control valves) comply with the below stated numbers of operating

hours at the total number of 1 million start-ups:

Switching frequency

max. 1,200 [h-1] 1,000 [h-1] 500 [h-1] 250 [h-1] 125 [h-1]

Minimal lifetime expectancy – number of operating hours

850 1,000 2,000 4,000 8,000

Time of net operation is min. 200 hours, max. 2,000 hours.
Lifetime at operating hours depends on loading and switching frequency.
Note : High switching frequency does not ensure better regulation. Setting of regulation parameters should be
therefore made with the inevitably necessary switching frequency needed for the process in question.

1.6 Operation conditions

1.6.1 Product location and operation position

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.
Installation and operation of EA is possible in any position. Vertical position of output part axis and with
the control part above the valve is usual. Electric actuator position under the valve not recommended.

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.

1.6.2 Operation environment

ES ST 1 are designed for remote control:

• short-time operation S2-10 min

• intermitted operation S4-25%, 6 up to 90 cycles per hour

ES STR 1 with controller are designed for automotic regulation:

• intermitted operation S4-25%, 90 up to 1200 cycles per hour

Note:

1. Duty cycle consist of load type, load factor and switching rate.

2. EA ST 1 is possible connect with an external controller and use this EA as controlled EA, for this EA stands
duty cycle and power parameters as for type STR 1 with built-in controller. For EA with controller we do not
suggest operating speed 63 and 80 mm per min.

1.7 Conservation, packing, transport, storing and unpacking

Surfaces without surface treatment are treated by conservation preparation MOGUL LV 2-3 before
packaging .
Conservation is not necessary if the following storage conditions are complied with:

• Storage temperature: -10 to + 60 °C

• Relative air humidity max.80 %

• 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

• There shall be no corrosive gases present in the storage areas.

6 ST 1, STR 1

The EA ST 1, STR 1 are delivered in solid packages guaranteeing resistance in accordance with EN 60 654

(IEC 60 654-1 and IEC 60 654-3).
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 self-motion;
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.
They can be transported in unheated and not airtight areas of transport means with effects in range:
temperature: -25°C up to +70°C (a strange version – 45 ° C up to + 45 ° C)
humidity: 5 up to 100%, with maximal content of water 0.029 kg/kg per kg of dry air
barometric pressure: 86kPa up to 108kPa

After receiving EA check whether during transport or storage the actuator was not damaged.
Compare also whether the parameters on their nameplates are in accordance with accompanying
documentation or the Contract. If any discrepancy or fault occur inform immediately your supplier.

If the actuators and accessories are not immediately installed, they have to be stored in dry, well­ventilated sheltered roos, protected against dirt, dust, soil humidity (with placing onto shelves or onto
pallets), chemical impacts and encroachment, at ambient temperature from -10°C up to +60 °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.

1.8 Appreciation of the product and packing

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.

3.1.2 Electric connection and checking of function

Follow up with connecting the EA with mains or master system.

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 screw bushings.

4. Before initiation EA 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 bushings.

6. 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)!

Connecting to terminal board

• Check whether the type of current, supply voltage and frequency correspond with data on the nameplate of

electric motor.

• Remove the upper cover.

• In case of the single-phase version the phase L1 and the lead N connect to the corresponding terminals. In

case of the three-phase version connect the phase cables L1, L2 and L3 to U, V, W (terminals 2, 3, 4), the
protection cables to the marked places of internal and external protection terminals.

For operating of armature without stop ends is needed to connect the positional switches S3, S4 to the wirring
power supply of electric motor before S1, S2. The switches S3, S4 are adjusted to the required stroke by
producer.

• Connect the control cables according to the wiring diagram placed into the internal side of the cover.

• Put the cover on and tighten it uniformly crosswisely.

• Tighten the cable bushings firmly to assure the protection enclosure rate.

Connection to connector:

• Check whether the type of current, supply voltage and frequency correspond with data on the nameplate of

electric motor.

• Release the connectors shells;

• Insulate the ends of conductors;

• Connect the appropriate sleeve connector by means of recommended pliers;

• Insert the sleeves into appropriate connector contacts according to connecting wiring diagrams.

• Fix the connectors and tighten them;

• Tighten the cable bushings firmly to assure the protection enclosure rate.

Notes:

1. 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.

2. 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.

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

4. 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.

5. 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.

6. Delay after switching-off, i.e. time since a reaction of switches till the motor is dead can be maximally 20 ms.

7. It is recommended to have the corresponding direction protection switched-off directly with the

corresponding position or thrust switches.

!

!

14 ST 1, STR 1

Abide by instructions of valve producers, whether switching-off in limit positions is to be
realised with position or thrust switches!

After electric connection perform checking of function:

• Put the valve manually to a mid-position.

• Connect the EA electrically for the chosen direction of movement and watch the output part movement.

• If it does not correspond change the order of feeding phases (valid for 3x400/3x380V version), or change

leads of the feeding phase to the corresponding terminals (valid for 230V/220 version).

• Check the control unit switches connection with switching consequently the contacts of the corresponding

switches with pressing the control elements at running of the EA (at proper connection) to the chosen
direction. In case of proper connection the EA stops or indicates the adjusted position according to switching
of the chosen switch. If any of the functions is fault check connecting of the switches according to wiring
diagrams.

In the STR 1 version with the built-in electronic controller (Fig.9) 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.

3.2 Dismantling

Before dismantling it is required to disconnect the EA from mains!
Do not connect and disconnect live connectors!

• Disconnect the EA from mains.

• Disconnect the leads from the EA terminal boards and loosen the cables from bushings. Pull out the

connectors in case of the connector version.

• Loosen the fixing screws of the EA flange and coupling screws 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.

4. Adjusting of actuator

Abide by safety measures!

After mechanical connection, electrical
connection and checking of connection and
function start setting and adjustment of the
device. 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. 3

4.1 Gear unit adjustment

In the production plant switching-off

thrust for both the "opening" direction (the
thrust switch S1) as well as for the "closing"
direction (the thrust switch S2) are adjusted to
specified value ±10%. If not agreed else they
are adjusted to maximum value.

Adjustment and setting of the gear unit to other values without any testing device for thrust measuring is
not possible.

4.2 Adjustment of position-indicating unit (Fig.4)

The EA are in the production plant adjusted to a fixed

angle (according to the specification), given on the nameplate.
While setting, adjusting and resetting follow these steps (Fig. 4):

• In the version with a transmitter put the transmitter out of

mesh.

• Loosen the nuts (23) fixing cams still having the Belleville

spring creating axial pressure.

• Put the EA to the position "open" and turn the cam (29)

clockwisely until the switch S3 (25) switches.

• Change setting of the EA by the angle, where the position

"open" is to be indicated and turn the cam (31) clockwisely
until the switch S5 (27) switches.

• Put the EA to the position "closed" and turn the cam (28)

counterclockwisely until the switch S4 (24) switches.

• Turn the EA back by the angle, where the position "closed" is

to be indicated and turn the cam (30) counterclockwisely until the switch S6 (26) switches.

• Having the EA adjusted lock the cams with the central milled nut and counter-nut (23).

If not agreed else the signalling cams are set next to the limit positions. The signal possibility is available
along the whole operation angle in both directions, i.e. 100%.

4.3 Adjustment of resistant transmitter (Fig. 5)

The resistant transmitter is in the EA ST 1 used to function as a remote position indicator; in the EA STR

1 with controller to function as a feedback in the position controller and if needed also in the position of a

remote resistant position indicator. Before the resistant transmitter adjustment the position switches have to be
adjusted. Adjustment consists in setting of the resistance in the defined limit position of the EA.

Notes:
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.
In the EA STR 1 with controller 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.

To adjust the transmitter follow these steps:

• Loosen the fixing screws (9) of the transmitter holder and push the

transmitter out of mesh.

• Connect a meter for resistance measuring to the terminals 71 and 73 of the

EA ST 1 terminal board, or to the terminals 6 and 7 of the EA STR 1 with
controller terminal board.

• Put the actuator to the position "closed“ (with the hand wheel, or with the

local electric position control until the corresponding position switch S2 or
S4 switches).

• Rotate the transmitter shaft until resistance of ≤5% of the nominal

transmitter resistance can be read on the meter in case of EA ST 1, or 3 up
to 7% of the nominal transmitter resistance in case of EA STR 1, or in case
of EA ST 1 with EPV, i.e. with the resistant transmitter with the converter PTK1

• In the position put the transmitter to mesh with the drive wheel and fix the fixing screws on the transmitter

holder.

• Disconnect the meter from the terminal board.

18 ST 1, STR 1

4.5 Adjustment of the Capacitive Transmitter CPT1/A (Fig.8)

The chapter describes adjustment of the capacitive transmitter to the specified parameters (standard

values of output signals) in case they are reset. The capacitive transmitter serves as a position transmitter of
electric actuators with unified output signal of 4÷20 mA in electric actuators ST, or as a feedback of a position
controller, or if required it functions also as a remote position transmitter of electric actuators with unified output
signal of 4÷20 mA in electric actuators STR with controllers.

Note:
In case that reversed output signals are needed (in the position ”OPEN” minimum output signal) contact
personnel of service centres.

The capacitive transmitter CPT1/A is adjusted by the producer to the fixed operation stroke according to
the order and wired according to the wiring diagrams placed into the cover. Check the power supply of the user
after connecting to terminal of the terminal board before the transmitter is electrically checked. Adjustment of the
capacitive transmitter can be performed when the position switches are adjusted. The adjustment is performed
with the power supply of 230 V/50 Hz and ambient temperature of 20±5°C.

The following versions of electric actuators with built capacitive transmitters can be specified :

A) The version without any power supply (2-wire version) for EA ST
B) The version with a power supply (2-wire version) for EA ST
C) The version CPT as a feedback to the position controller for EA STR with controllers

A.) Adjustment of the Capacitive Transmitter without any Power Supply

Before connecting check the power supply. The measured voltage should be in range from 18 up to 28 V DC.

The voltage of the power supply must not be in any case higher than 30 V DC. The transmitter can be
irreversibly damaged

While checking or adjusting the output signal of 4÷20 mA follow these steps:

• Connect a mA meter of precision class 0,5 and loading resistance lower than
500Ω serially with the transmitter (pole „-„; terminal 82)

• Put the actuator to the position ”CLOSED“, the signal value should decrease.

• Check the signal value for the position ”CLOSED“ (4 mA).

• Tune the signal with loosening the fixing screws (15) and turning the trimmer (10)

until the required value of 4 mA is reached. Tighten the fixing screws.

• Put the actuator to the position ”OPEN“, the signal value should raise.

• Check the signal value for the position ”OPEN“ (20 mA).

• Tune the signal with turning the trimmer (20) until the required value of 20 mA is

reached.

• Check the signal value for the position ”CLOSED“ and then for the position ”OPEN“.

• Repeat the procedure until the change from 4 to 20 mA is reached with deviation less then 0,5 %.

• Disconnect the meter and lock the screws with a varnish.

B.) Adjustment of the Capacitive Transmitter with the Power Supply:

1.) Check the power supply: 230 V AC ±10% on the terminals 78,79

2.) While checking or adjusting the output signal of 4÷20 mA follow these steps:

• Connect a mA meter of precision class 0,5 and loading resistance lower than 500Ω on the terminals 81,82.

• Follow the procedure described in the previous chapter A.

C.) Adjustment of the Capacitive Transmitter Served as a Feedback of the Position Controller

While checking or adjusting the output signal of 4÷20 mA follow these steps:

• Disconnect the circuit on the terminals 81 and 82 removing the jumper.

• Connect power supply to the terminals 1 and 61.

• Disconnect the control signal from the terminals 86 and 88.

• Put the actuator to the direction ”OPENING“ or ”CLOSING“ with the hand wheel or connecting power supply

to the terminals 1 and 200 for the direction ”OPENING“, or 1 and 24 for the direction ”CLOSING“.

• Connect a mA meter of precision class 0,5 (e.g. digital) and loading resistance lower than 500Ω on the
terminals 81,82.

• Follow the procedure for the version without any power supply described in the previous chapter A.

• Having the transmitter adjusted put the jumper again on the terminals 81 and 82 in case that the

output signal wont be used (the circuit through the terminals 81 and 82 should be closed).

ST 1, STR 1 19

• Connect the control signal to the terminals 86 and 88

The user has to arrange grounding of the 2-wire circuit of the capacitive transmitter to the electrical
ground of a joined controller, computer, etc. The grounding should be performed only in one place in
any part of the circuit outside the electric actuator!

Note:
The trimmer (20) can be used to adjust the output signal of the capacitive transmitter to any value of operation
stroke in range from ca 40% up to 100% of the value of the operation stroke adjusted by the producer and stated
on the actuator′s nameplate.

4.6 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.

4.6.1 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.

Laying of adjusters and signalling elements on the board of the REGADA controller is shown on Fig.9:

Notes:

1. The controller at autocalibration automatically sets the feedback type - resistant/current

2. (*) Parameters set in the production plant, if customer has not stated else.

3. (**) Input signal 4 mA - position "closed"
20 mA - position "open"

Standard setting of controller (programmed RESET of controller) - in case of any problems with setting of
the parameters it is possible with pressing both SW1 and SW2 at the same time and then switching power on to
set the standard parameters.

Controller setting procedure:

• Set the actuator into a mid-position.
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

transmitter

4.6.2 Watching operation and error states

Watching operation and error states is possible with the EA open.

a.) Operation status with the D3 LED diode indicating:

• it is continuously lighting - the controller regulates

• it is continuously not lighting - system deviation in the insensitiveness range - the EA has stopped

b.) Error state with the D4 and D3 LED diodes indicating - D4 continuously lighting, D3 indicates

error state with blinking

1 blink (repeated): - indication of the "TEST" mode - the EA is put to the position

according to the signal in the "TEST" menu (at connecting the 66
and 86/87 terminals)

2 blinks (repeating after short pause): - missing of control signal - the EA is put to the position according to

the signal in the "TEST" menu

4 blinks (repeating after short pause): - thrust switches activity indication (the EA switched-off with the

thrust switches in a mid-position)

5 blinks (repeating after short pause): - failure of the feedback transmitter - the EA is put to the position

according to the signal in the "TEST" menu

7 blinks (repeating after short pause): - control signal (current at range 4-20mA less than 4mA (3.5mA)

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!

The EA ST or 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.

Manual control:

If needed (during adjusting, function checking, failure etc.) the stuff can change setting of the controlled
body using the hand wheel. While rotating the hand wheel clockwisely the output part moves in the direction "Z ­closed".

Electric local control: - additional
equipment
In case of need (during
adjusting, function checking etc.),
but power supply must be provided,
is possible to readjust actuator by
electric local control. After switching
the mode switch to the mode
“LOCAL” it is possible by the
direction switch to control motion of
the output part to setting direction.
Signal lights indicate achievement of
limit position at relevant direction.

5.2 Maintenance - extent and periodicity

During inspections and maintenance is needed to tighten all screws and nuts that affect the tightness and
coverage. 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 interval between two preventive inspections is four years.
The replacement of cover gaskets and gasket of an oil filling is needed in case of damage or after 6 years of the
operation.

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 - in versions for climate with temperatures -25°C till +55°C – grease HF 401/0 (GLEIT-µ) resp.
GLEITMO 585 K

- in versions for climate with temperatures -50°C till +40°C grease ISOFLEX TOPAS AK 50.

• - linear adapter – grease GLEIT- µ - HP 520M (to –25°C) resp. HP 520S (to –40°C).

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.

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 under­guaranty 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!

Notes:

1. In case, that output signal from capacitive transmitter (wiring diagram Z241a) is unused (incomplete circuit
between terminal 81 and 82), it is required to connect terminals 81 and 82 by jumper (jumper is connected at
manufacturing plant for connecting to terminal board only). By using output current signal from capacitive
transmitter it is needed to remove jumper.

2. In the version equipped with the controller device while using the feedback from transducer CPT; when using
the output signal there has been no galvanic isolation of the signal from the input one!

3. In case that galvanically separated output signal is needed it is necessary to use galvanical separation
element (is not part of delivery), e.g. NMLSG.U07/B (producer SAMO Automation s.r.o.). After discussion this
module could be supplied by EA producer.
