this compartment and can be easily accessed
after lifting off the actuator cover.

The electric actuator is a linear actuator. It is
suitable for mounting on Series 240, 250
and 280 Valves with 15 to 120 mm travel.

3.1 Torque switches and travelswitches

The actuator is fastened to the valve bonnet
with a ring nut. The actuator and plug stems
are fastened together by a stem connector.
Depending on the version, the Type SAM
Electric Actuator has a reversible DC, AC or
three-phase motors. It has an internal antirotation fixture.

Torque switches

Principle of operation− Two torque switches DE-S1 and DE-S2(designed as changeover switches)
They switch off the motor when the force
acting on the actuator is counterbalanced by a corresponding force. As aresult, they protect the valve from damage and the actuator from overload.

The rotary motion of the motor is transmitted
to the nut-threaded gear via a spur gear.
The actuator stem, which is protected against
rotation, has a male thread that engages thenut thread.
The actuator stem performs a linear motion
when the nut-threaded gear is turned by thegear of the motor.

The DE-S1 switch deactivates the motor
based on the torque when the actuatorreaches the lower end position (valve
closed).

The axial motion of the actuator stem istransferred via the adjusting lever and slider
to the driving lever. The driving lever produces a proportional rotary motion using a gear
wheel as a measure for the two potentiometers R1 and R2 or the position transmitter
ESR. The cam disks located on the gear
wheel operate the switches WE-S3, WE-S4,
WE-S5, and WE-S6.

! NOTICE

The electrical components are housed beneath the sealed actuator cover in a compartment where they are separated from thegearing. They are protected against dust in

EB 8330 EN

The DE-S2 switch deactivates the motor
based on the torque when the actuatorreaches the top end position.

Risk of valve damage due to retracting actuator stem.
The motor can only be deactivated by theDE-S2 switch when a force-dependent deactivation with a retracted actuator stem is possible with the valve used (see valve documentation).
Î Check whether a force-dependent deactivation of the actuator is permissible witha retracting actuator stem.

Note
The switching points of the DE-S1 and DE-S2
switches are preset by SAMSON and cannot
be changed.

S6
Extends− Two travel switches WE-S4 and WE-S5 toindicate the intermediate and end positions of the actuator stem
The WE-S3 switch deactivates the motor depending on the travel when the actuator stem
retracts (provided the actuator stem has completed the travel specified in the order).
The travel switches WE-S4, WE-S5 andWE-S6 (if installed) are not preset. They canbe adjusted to indicate the end position or
an intermediate position, if required (see the'Start-up' section).

Fig. 3-1: Cam of WE-S3 and WE-S6

Depending on the actuator movement toextend or retract the actuator stem, theassociated switch deactivates the actuator
depending on the travel.

The travel switches WE-S3 and WE-S6 in
Types SAM-01 to SAM-11 Actuators aremounted on a side mounting plate. They areoperated by the cam mounted on the top
end of the actuator stem.
Note
If a fourth travel switch WE-S6 is installed,only one potentiometer R1 can be installedin the actuator version with plug connector.

3.2.1

Positioner

The positioner compares the control signal issued by the controller with the position of apotentiometer which is proportional to thetravel. When the actual value deviates fromthe set point, a signal (manipulated variable)
is issued to control the actuator.
A 0 to 10 V, 0 to 20 mA, 2 to 10 V or 4 to
20 mA signal can be used to control the actuator.
The positioner can be adjusted in such a
way that the actuator is deactivated either by
the switches (DE, WE) or by the positioner itself when the actuator reaches the end positions. To determine the position of the actuator stem, the potentiometer R1 to track theactuator's travel movement is required in theactuator.

Fig. 3-3: Positioner PEL 100

The travel calibration, split-range operation,
reversed direction of action and dead bandsettings are changed using the potentiometers and switches (see Annex A).
The dead band determines how sensitive theactuator reacts (see Annex A).
The wire breakage detection function allows
input signal failures to be detected (see Annex A).

Special functions
An additional device makes it possible to set
special functions (e.g. split-range operation.

3.2.2

Fig. 3-5: Positioner PEL 200 for DC supply

DIP switches and keys are used to select therequired parameter settings.
LEDs on the printed circuit board are used toindicate certain status alarms (see Annex A).
Direction of action
The direction of action (increasing/increasing >> or increasing/decreasing <>) can beselected at the switch without having to perform a recalibration.
Manual operation
The actuator stem can be extended or retracted by pressing a key. A different key isused to set the manual/automatic mode.

Position transmitter ESR

The position transmitter ESR is used for remote analog transmission of the valve stem
position. A potentiometer is used to issue acurrent signal, which is proportional to thetravel.
The position transmitter is adjusted to the required travel. Readjustment is possible (seethe 'Start-up' section).
The transmitter indicates the current travel
position by issuing an output current between 0/4 and 20 mA. As a result, it is particularly suitable for remote transmission of
the valve position.
The position transmitter can be operated innormal operation or with reversed directionof action (see the 'Start-up' section).

3.2.3

Travel switch WE-S6

A fourth travel switch WE-S6 allows additional indication of valve stem positions.

Input signal failure
The action of the actuator stem can be defined by setting certain switches.
Deactivation in end position
The deactivation in end position can be selected as required.
Hysteresis
The hysteresis is set at the DIP switches.

3.2.5

Heating

A heating resistor serves to prevent condensate from forming underneath the actuator
cover, e.g. when the humidity is high, when
the ambient temperatures fluctuate considerably or when the actuator is installed outdoors.
The heating resistor is controlled by a temperature switch TW (bimetallic contact). A
constant supply voltage (to be specified at
the ordering stage) is required to operate theheating.
The deactivation temperature is approx.
60 °C and the reactivation temperature approx. 40 °C.
Fig. 3-6: Switches and resistance transmitters

3.2.4

Resistance transmitters

Optionally, the actuator can be equippedwith one or two resistance transmitters. They
are linked to the gear of the actuator. They
consist of one potentiometer, which produces
a resistance signal proportional to the travel.
It can be used to assess the process of theactuator stem.

3.2.6

Reversing contactor

For actuators for multi-phase operation oroperation of the three-step control version
with a 24 V DC supply, a reversing
contactor is required to be able to change
the direction of the actuator stem. It can beconnected through external wiring.
The reversing contactor can also be readyinstalled on delivery for multi-phase operation.

The axial motion of the actuator stem istransferred via the adjusting lever and slider
to the driving lever. The driving lever produces a proportional rotary motion using a gear
wheel as a measure for the two potentiometers POT R1 and POT R2 (see Fig. 3-6).
The potentiometers are preset to the required
travel. Readjustment is possible (see the'Start-up' section).

Installation

If the actuator is installed outdoors, it must
be protected by an additional cover, e.g.
against humidity (rain, snow), heat (direct
sunlight), frost, strong drafts, dust etc.
If the actuator is exposed to high humidity
and ambient temperatures that fluctuate considerably, we recommend installing a heating resistor to minimize condensate formation in the housing (see the 'Design and principle of operation' section).
If the actuator is installed in ambient conditions with high concentrations of pollutants(e.g. areas with a high traffic volume, industrial areas, coastal regions), the external actuator parts must be made of stainless steel
and have a special paint coating.

5.4 Retrofitting a heating
resistor
1. Take off the actuator cover.
2. Fasten the heating resistor at the intended location (see Fig. 5-4) using the two
supplied self-tapping screws.
3. Fasten the temperature switch in the holeof the mounting bracket using a nut withwidth across flats SW 7.
4. Connect the wires of the temperatureswitch and the heating resistor to terminals 7 and 8.
5. Route and secure the wiring in the actuator in such a way that it is protectedagainst moving or rotating parts andcannot be damaged while removing or
replacing the actuator cover.

5-4

Heating resistor (bottom), temperature switch (top)

5.5 Electrical connection
The wiring diagram inside the actuator coverapplies for electrical connection.
! DANGER
Risk of fatal injury due to electric shock.
Î Upon installation of the electric cables,
you are required to observe the regulations concerning low-voltage installations
according to DIN VDE 0100 as well as
the regulations of your local power supplier.
Î Use a suitable voltage supply whichguarantees that no dangerous voltages
reach the device in normal operation orin the event of a fault in the system or
any other system parts.

EB 8330 EN

Installation

Î Only connect the actuator to the power
supply after switching off the supply voltage. Make sure the supply voltage cannot be switched on again unintentionally.
Î Select the wire cross-section of the lines
to match the actuator's power consumption and the required line length.
Î Minimum wire cross-section: 1.5 mm² (oras specified in the local regulations).
Î Circuit breaker installed in the plant:
max. 6 AÎ Make sure controllers or switchgear connected in front of the actuator are sized
sufficiently. If required, install a coupling
relay between them.
Î Make sure that sufficiently large wirecross-sections and reserve capacities forthe transformer are used especially for
24 V actuators.
NoteSpecial motor electronics ensures that thecontacts of the controller's output relay (e.g.
for three-step control) are protected and only
loaded with relatively low control capacities
when the actuator is wired according to thecircuit diagrams.
The power switching is performed by a TRIAC and a relay in the motor electronics.
! NOTICE
Risk of actuator damage due to the motor
not being deactivated on reaching the end
positions.
Î Wire the limit switches.

EB 8330 EN

When an external reversing contactor unit isused, the limit switches are not wired (upondelivery). The switches must be wired onconnecting the external reversing contactor
unit. The actuator will be destroyed if itreaches the end stops and the motor cannot
be switched off by the limit switches.
! DANGER
Risk of electric shock on touching exposed
live parts.
Î Switch off the supply voltage and protect
it against unintentional reconnection before removing the actuator cover andwhen performing calibration or maintenance work.
! WARNING
Risk of personal injury due to exposed,
moving or rotating parts.
Î Do not touch moving or rotating parts
while performing calibration work.
Î Only operate the actuator briefly without
the actuator cover while testing it or calibrating electric components (e.g. potentiometers, travel-dependent switches orpositioner).
! NOTICE
Risk of wire damage.
Î Route and secure the wires in the actuator in such a way that they are protectedagainst moving or rotating parts andcannot be damaged while removing or
replacing the actuator cover.

Operation

6.2 Manual override
The actuator stem can be extended or retracted manually using the handwheel in theevent of a power supply failure or when installing or adjusting the actuator (see the'Operation' section).
! NOTICE
Risk of actuator damage due to incorrect
use of the handwheel.
Î Do not operate the handwheel while themotor is in motion.
Î Do not move the stem with the handwheel beyond the adjusted travel range(see 'Permissible limits" in the 'Design
and principle of operation' section).
Unlocking the motor
Before the handwheel can be used to movethe actuator stem, the motor must be unlocked mechanically using the disengaging
lever (see Fig. 6-2 and the 'Operation' section). The actuator returns to motor operation
automatically as soon as the disengaging lever is released.

EB 8330 EN

Start-up

7 Start-up
Adjusting the travel
Upon delivery, the actuator is adjusted to the travel specified in the order.
Î If required, this default travel can be changed or adjusted.
The slotted lever connected to the actuator stem has travel markings. The adhesive scale indicates adjustable travel values.
! NOTICE
Risk of actuator damage due to the actuator stem being moved outside the permissible
range.
Î Observe the permissible limits on retracting or extending the actuator stem (see the 'Design and principle of operation' section).
This applies to all operations in which the actuator stem is moved manually.
How to proceed:
1. Extend the actuator stem to the lower end position. The two positioning levers are parallel
to each other (travel indicator at the bottom marking).
2. Use an open-end wrench with width across flats (SW) 10 to remove the flat nut from theslider.
3. Move the slider between the two slotted levers to set the desired travel according to thetravel markings.
4. Secure the slider again using the flat nut.
5. Move the position indicators on the yoke to the new end positions.
Note
The travel can be adjusted continuously as specified on the nameplate (see the 'Markings on
the device' section). Remember to readjust the travel-dependent switch WE-S3 as well after thetravel has been changed.

EB 8330 EN

7.1 Three-step version
1. Make sure that the supply voltage is connected to the terminals.
2. Use the handwheel to move the actuator stem to 50 % of the travel range (see the 'Operation' section).
! NOTICE
Risk of actuator damage due to the actuator stem being moved outside the permissible
range.
Î Observe the permissible limits on retracting or extending the actuator stem (see the 'Design and principle of operation' section).
3. Briefly apply the supply voltage separately to each terminal for the direction of action extending and retracting.
! NOTICE
Risk of actuator damage due to incorrect direction of rotation of the motor.
Î Pay attention to the correct connection for "retracting" and "extending".

7-2

EB 8330 EN

Start-up

4. Check whether the actuator stem moves in the right direction. If this is not the case, exchange the connections as described in the 'Installation' section.
5. Use an insulated screwdriver to operate the switching rollers of the switches and check
whether the switches really deactivate the motor:
Î When the actuator stem extends:
top switch DE-S1
Î When the actuator stem retracts:bottom switch DE-S2
Î If required, switch the motor supply jumpers at terminals 2 and 3.

7.2 Positioner
A calibration must always be performed to ensure that the positioner can function properly.

7.2.1

Calibrating the travel in positioner PEL 100

The positioner is adjusted by SAMSON for the specified travel. As a result, only slight calibrations are necessary.
1. Apply the lower value of the input signal range (0 or 4 mA, 0 or 2 V).
2. Turn potentiometer P1 counterclockwise until the actuator is deactivated by the associatedswitch and LED V19 just remains illuminated.
Î Check the switching behavior by turning the potentiometer.
3. Apply the higher value of the input signal range.
4. When the switch is deactivated, turn potentiometer P2 clockwise until the LED V18 blanks
out. Then turn potentiometer P2 counterclockwise until the LED reilluminates.
Note
If the potentiometer's full angle of rotation cannot be used when the travel is very small, use
the spreading function to adapt the input range. Activate this function by setting switch S1.2
to OFF (see Table 7-2).
5. If required, turn potentiometer P4 counterclockwise to shift the top deactivation point.

Autotune function in PEL 200

u Fig. 7-4 and u Fig. 7-5
The positioner PEL 200 comes with an automatic calibration (autotune) function. The following requirements must be met before it can be started:− The actuator must be mounted on the valve as described in the 'Installation' section.
− The signals and indicators must be adapted correctly to the travel.
− The potentiometer must be set to the maximum setting over the sliding clutch.
! NOTICE
The actuator will be damaged as a result of using the autotune function without a valve.
Î Do not start the autotune function before the actuator is mounted on a valve or without asuitable mechanical stop, which prevents the slide rod from falling out.
An appropriate external stop must exist when the DE setting is used.
Start autotune function

The potentiometers R1 and R2 must be set in the corresponding end position depending on theirfunction.

Fig. 7-11: Potentiometers R1 and R2

7-14

EB 8330 EN

Start-up

1. Use the handwheel to move the actuator stem to the lower end position until DE-S1
switches.
Note
Make sure the adjusting lever and driving lever are parallel in their tilted position.
2. Use a suitable screwdriver to move the potentiometers' slider to its end position.
To do so, turn the potentiometer shaft counterclockwise until the stop can be felt slightly.
3. Move the actuator stem over the adjusted travel to the top end position. The potentiometers move in the opposite direction.
4. Use an ohmmeter to monitor the potentiometer movement and check whether the potentiometer is moved through its entire resistance range.
Note
If the potentiometers reach their stops when moving to their end positions, the sliding clutch between potentiometer and pinion is activated and prevents the potentiometers from being damaged. This means, however, that the measurement results can no longer be reproduced clearly.
In this case, adjust a larger travel using the slider and positioning lever (see Fig. 7-1).
Note
If the actuator is fitted with a positioner, the resistance transmitter POT R1 is used as internal
position feedback. Its signal is not issued. In this case, only POT R2 is only available as a resistance transmitter.

8.1 Three-step control
The actuator stem of the version with threestep signal is moved in the corresponding direction (retracting or extending) by applying
a signal to the terminal as specified in thecorresponding wiring diagram.

8.2.1

8.2 Positioner
The positioner ensures a predetermined assignment of the valve position to the input
signal. The position feedback is issued as acurrent or voltage signal at the corresponding terminals (see the 'Installation' section).
The characteristic of the output signal is thesame as that of the input signal (e.g. both 4
to 20 mA).

Annex A (adjustment instructions)

16 Annex A (adjustment instructions)16.1 Changing settings at the positioner PEL 100
Switches S2 and S3 as well as potentiometers P1, P2 and P4 allow the travel calibration,
split-range operation, reversed direction of action and dead band settings to be changed(see Table 16-1 and Table 16-2).
The DIP switch settings of switch S1 allow additional functions to be adjusted (e.g. zero setting, spreading of the resistance signal for the potentiometer and behavior upon input signal
failure). The positioner comes with a minimum dead band of 200 ms to prevent suddenchanges in direction or the rapid activation and deactivation of the actuator.
By default, a position feedback signal is issued, which indicates the current position of theactuator stem. The signal range corresponds to the input signal range.
The position feedback signal is not isolated from the input.
The type of input signal (voltage or current) is determined by the terminal assignment.
Switching or changes to the soldering connections are not necessary.

16.1.1 Setting the input and output signals
The input and output signals are set to either 0 to 10 V, 0 to 20 mA or 2 to 10 V, 4 to
20 mA. Depending on the configuration, the lines for the input and output signals are connected to terminal X4. The configuration of the positioner can be changed as described in
the 'Installation' section.
Note
Before changing the input signal, it may be necessary to change the terminal assignment as
described in the 'Installation' section.

3. Use potentiometer P1 to adjust the voltage to 0.0 V.
4. Measure the voltage between measuring point 3 and 4.
5. Use potentiometer P2 to adjust the voltage to 10.0 V.

16.1.2 Adjusting the dead band
The adjusted dead band depends on the actuator. It is preset by SAMSON and must not bechanged.
Î Set the switch S2 to required position (see Table 16-2).
Note
If the dead band is set too small, the actuator oscillates around the set point, causing premature wear of the positioner and actuator. If oscillations are detected, they can be reduced byincreasing the dead band.
Make sure the adjusted values are retained when replacing the positioner.

Annex A (adjustment instructions)16.1.3 Reversing the direction of action
The actuator's direction of action can be reversed by changing the setting of switch S3. It
may be necessary to adapt the end positions and travel (see the 'Start-up' section).

16.1.4 Activating the detection of wire breakage function
Î Activate or deactivate the detection of wire breakage function at switch S1.5 (seeTable 16-2).
! NOTICE
Risk of positioner malfunction due to incorrect settings.

1. Apply the input signal for the top end position (e.g. 12 mA).
2. Turn potentiometer P2 until the travel corresponds to the top end position.
Note
Turning the potentiometer P1 counterclockwise causes the actuator stem to retract. The lowest
value adjustable for the top deactivation point is approx. 8 mA or 4 V.
3. Apply the input signal for the lower end position (e.g. 6 mA). Turn potentiometer P1
counterclockwise to extend the actuator stem.
Note
Turn potentiometer P1 counterclockwise to change the position of the actuator stem in the 'extending' direction.
4. Check the adjustment by moving the actuator to its top and lower end positions again.
