1 Safety instructions and measures
The Type3374 Electric Actuator is designed to operate a mounted globe valve used in
industrial applications as well as in heating, ventilation and air-conditioning systems. The
digital positioner ensures a predetermined assignment of the valve position to the input
signal. The actuator is designed to operate under exactly dened conditions (e.g. thrust,
travel). Therefore, operators must ensure that the actuator is only used in applications that
meet the specications used for sizing the actuator at the ordering stage. In case operators
intend to use the actuator in other applications or conditions than specied, contact
SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data for limits and elds of application as well as possible uses. See
section3.6.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
− Use outside the limits dened during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described in these instructions
Qualicationsofoperatingpersonnel
The actuator must be mounted, started up, serviced and repaired by fully trained and qualied personnel only; the accepted industry codes and practices are to be observed. According to these mounting and operating instructions, trained personnel refers to individuals who

3 Design and principle of oper-
ation
The Type3374 Electric Actuator is used in
industrial plants as well as in heating, ventilation and air-conditioning systems.
The actuator is suitable for form-t attachment to various SAMSON valve series, depending on the version with or without fail-safe action.
The stepper motor is switched off by
torque-dependent switches in the end positions or in case of overload. The force of the
motor is transmitted to the actuator stem via
gearing and ball screw.
The Type3374 Actuator is optionally available with either integrated yoke (Fig.1) or
using an M30x1.5 ring nut (Fig.2) including
the necessary stem connecting parts.
TestingaccordingtoDINEN14597
The Types3374 Electric Actuator with fail-
safe action "actuator stem extends" is tested
by the German technical surveillance association (TÜV) according to DINEN14597 in
combination with various SAMSON valves.
The register number is available on request.

3.2 Limit contacts
The actuator can be equipped with either
mechanical or electronic limit contacts to in-
uence the tasks of control equipment.
3.2.1 Mechanical limit contacts
The two mechanical limit contacts can be adjusted independently from one another. They
are operated by mechanical pins. The instal
lation and adjustment of the mechanical limit
contacts is described in section6.1.
-
3.2.2 Electronic limit contacts
The two electronic limit contacts consist of relays with changeover contacts. In contrast to
the mechanical limit contacts, the electronic
limit contacts no longer function after a power
supply failure. The relays are de-energized
and the contacts change to the idle state. The
retrotting and adjustment of the electronic
limit contacts is described in section9.8.
3.3 Manual override
There are two ways to manually move the
actuator stem:
− Manual override with 4mm hex wrench
− MAN operating mode to move the actu-
ator stem manually
3.3.1 Mechanical override
The mechanical manual override is only possible for actuators without fail-safe action. It
is performed by placing a 4mm hex wrench
on the red actuator shaft located at the side
of the housing. The hex wrench is included in
the scope of delivery. It is attached to the
bottom of the housing.
Î Do not operate the manual override
while the actuator is running and only
when the power supply is disconnected.
3.3.2 Moving the actuator
stem manually
First place the actuator into MAN mode to
move the actuator stem manually. The operation and selection of the operating mode
are described in section8.1 on page42.

6.3 Setting up Modbus-RTU
communication
The electric actuator can be connected to a
control station over Modbus and can be con-
gured using TROVIS-VIEW. For this purpose, the actuator with rmware version
3.10 and higher can be tted with an RS-
485 module. Various communications protocol (SSP or Modbus-RTU slave) are used for
various functions.
For Modbus-RTU communication, the RS-485
module (order no. 1402-1522) must be inserted into the actuator.
Î Excerpt from Modbus list: see sec-
tion17.2.8.
6.3.1 Protocol
− Setting:automatic
The SSP and Modbus-RTU protocols are
automatically detected: the interface pa-
rameters are xed internally to Baud rate
9600bit/s, 8data bits, no parity, 1stop
bit. The electric actuator can exchange
data with TROVIS-VIEW or the control
station without switching over. The station
address and bus failure monitoring are
adjustable.
− Setting:Modbus-RTU
Communication is based on the Modbus-RTU protocol. All interface parameters listed in 6.3 are adjustable.
Note
General information on operating the elec-
tric actuator: see section7.
Station address (Code A64)
The station number is used to identify the
electric actuator for the Modbus-RTU protocol.
Baud rate (Code A65)
It is the transmission rate between the electric
actuator and control station/computer. The
Baud rate adjusted at the electric actuator
must be the same as that in the control station. Otherwise, no communication is established.
Stop bit and parity (Code A66)
The number of stop bits and the parity are
set in Code A66. The parity is used to detect
data transmission errors. The parity bit is
added to the end of the string of data bits
and the total value is made up from the data
and parity bit.
Bus failure monitoring (Code A67)
The external manual level of the communication is monitored by the bus failure monitoring (timeout). After a bus failure is detected,
automatic operation is reestablished. The
time for the bus failure monitoring is adjustable. Set the value to 0 to deactivate bus
failure monitoring.

Î Set Code 6 to POSI.Î Use terminal assignment according to Fig.16.
EB 8331-4 EN 45
Operating level
PID controller application
The set point adjustable at the actuator is used to position the valve using a PID algorithm.
The input signal is used as the process variable. The PID controller is adjusted using the parameters: Proportional-action coefcient Kp, Reset time Tn, Derivative-action time Tv and Op-
erating point Y
:
0
The proportional-action coefcient Kp acts as gain.
The reset time Tn is the time it takes for the integral component during a step response in a PI
controller to produce a change in the manipulated variable identical to the change produced
by the P component. Increasing the reset time Tn reduces the rate of change in the output
when the set point deviation is constant.
The derivative-action time Tv is the time it takes the rise response of a PD controller to reach a
certain manipulated variable value earlier than it would take the response with the P component only. Increasing the derivative-action time Tv causes an increase in the manipulated
variable amplitude when the rate of change is constant. After ramped changes of the set
point deviation, a longer derivative-action time Tv causes the D component to have a longer
effect.
The operating pointY
determines the positioning value, which is fed to the controlled system
0
when the process variable is the same as the set point. The operating point is normally only
important for P and PD controllers, but it can also be set for control strategies PI, PID and I
due to the possible limitation of the integral-action component. For control strategies with integral-action component, the operating point can also be used as the initial value for a restart.
Î Set Code 6 to PID.Î Use terminal assignment according to Fig.17.
Two-step mode application
The binary input IN2 is used for this function. When the binary input is in the active switching state, the actuator stem retracts to 100% of the adjusted travel range. When the binary
input is in the inactive switching state, the actuator stem moves to the closed position (0%).
Î Set Code 6 to 2STP.Î Use terminal assignment according to Fig.18.
Three-step mode application
The binary input IN2 is used for this function to retract the actuator stem and binary input

The input signal determines the actuator stem position. Either a current or voltage signal can
be applied to the input depending on the conguration in Codec01. The default lower and
upper range values of the input signal are 2 to 10V or 4 to 20mA. The input signal range
can be adapted, e.g. to achieve a plant operation characteristic by connecting two or more
actuators in parallel (split-range operation).
Note
The input signal must be ≥0.5V or ≥1mA.
Example: Two valves regulate the process medium in one common pipeline to achieve a
large rangeability. One valve opens with a 0 to 5V input signal, while the second valve also
opens when the input signal increases further (5 to 10V) and the rst valve remains open.
The two valves close in the reverse order.
Note
At least 2.5V or 5mA (depending on the input signal used) must separate the upper and
lower range values.

The function of the binary input can be congured as required. Code c12 is used to determine the switching state for the active function. c12=NINV: the binary input is active when
the input terminals IN4+/IN4– are connected with each other. c12=INV: The binary input is active when the connection between the input terminals IN4+/IN4– is interrupted.
Î Do not connect an external power supply to the input terminals.
− Inactive(c11=NONE): No function is assigned to the binary input.

9.10 Blockage
Blockage detection (c51)
The actuator detects a valve blockage by comparing the travel after the torque-dependent
switch has been triggered with the travel measured on initialization. If the comparison shows
that the limit switch was triggered too early, this indicates that there is a valve blockage. A
blockage is indicated on the display by the
icon.
Remove blockage (c52)
When the Blockage removal function is active, the actuator stem extends and retracts 1 mm
at the adjusted stroking speed three times at the most in sequence.
Blocking protection (c53)
The blocking protection prevents the valve from seizing up. If the actuator stem is in the
closed position (0 %), it is extended slightly and then moved back to the closed position 24
hours after it last moved.

9.14 Plausibility error
Due to an invalid combination of interacting parameters in the conguration level, a plausibility error arises which is indicated by PLAU blinking on the display. A correction of the interacting parameters resets the error message.
Causes of plausibility error
− Invalidapplicationselected(whenCodec01=C):"Pt1000" (Code c01 = C) is set as the source (only available for PID controller application, Code 6 = PID). Afterwards, the application is changed to "Positioner" (Code 6 =
POSI) or "Temperature closed-loop control upon input signal failure" (Code 6 = POSF),
causing a plausibility error.
Recommendedaction: Set Code 6 to PID controller.
− Invalidapplicationselected(whenCodec01=VIA):
"Interface" is set as the source (Code c01 = VIA). Afterwards, the application is changed
to "Temperature closed-loop control upon input signal failure" (Code 6 = POSF), causing
a plausibility error.
Recommendedaction: Set Code 6 to positioner or PID controller.
− Invalidvalueforlowerrangevalue(Codec02):A value <1.0mA or <0.5V is set in Code c02 combined with an active detection of input signal failure (Code c31 = YES).
Recommendedaction: Set Code c31 to NO or c02 to a value ≥1.0mA or ≥0.5V.
− Invalidvalueforlowerrangevalueduringfastconguration(FCO):
Lower range value (Code c02) and active detection of input signal failure (Code c31 =
YES) are a valid combination. However, a plausibility error arises if an input signal from
0 to 20mA or 0 to 10V is selected through fast conguration.
Recommendedaction: Set Code c02 to a value ≥1.0mA or ≥0.5V.
− Invalidsetpoint(Codec81):The set point (Code c81) is not within the range dened by the lower (Code c86) and upper adjustment limits (Code c87).
Recommendedaction: Set the set point (Code c81) or the adjustment limits (Code c86/
c87) so that the set point is within the adjustment limits.
The set point (Code c81) is within the range dened by the lower (Code c86) and upper
adjustment limits (Code c87). The lower limit of process variable range (Code c88) has a
greater value than the lower adjustment limit (Code c86) or the upper limit of process
variable range (Code c89) has a lower value than the upper adjustment limit (Code c87).
Recommendedaction: Adjust the limits of the process variable range (Code c88/c89) so
that they are identical to the adjustment limits (Code c86/c87) or that the adjustment limits (Code c86/c87) are within the limits of the process variable range (Code c88/c89).

17.2.8 Excerpt from Modbus list
The electric actuator in rmware version 3.10 and higher can be tted with an RS-485 module to use the Modbus-RTU protocol. This protocol is a master/slave protocol. In this case, a
control station is the master and the electric actuator the slave, for example.
The following Modbus functions are supported:
CodeModbus functionApplication
1Read CoilsRead state of several digital outputs in bit format
3Read Holding RegistersRead several parameters
5Write Single CoilWrite a single digital output in bit format
6Write Single RegisterWrite a value into a single holding register
15Write Multiple CoilsWrite several digital outputs in bit format
16Write Multiple RegistersWrite a value into several holding registers
The electric actuator can issue the following Modbus error responses:
Error code ErrorCause
1Illegal functionThe function code is not supported.
2Illegal data addressA register address is invalid or write-protected.
3Illegal data valueA value contained in the data is not allowed or not
plausible.
4Slave device failureAn unrecoverable error occurred during an action.
6Slave device busyThe slave is busy and cannot accept the query.
Several important data points from the Modbus data point list are listed below. The entire data point list is available on request.

Note
Data are saved in a non-volatile EEPROM. This type of memory has a limited life of at least
100,000 write operations per memory address. It is almost impossible to exceed this limitation if congurations and data are only changed manually using TROVIS-VIEW or at the de-
vice. If parameters are changed automatically (e.g. by Modbus communication), make sure
to observe the maximum number of write operations and take appropriate action to prevent
that parameters are written too frequently.
