1. APPLICATION
The electric actuators MODACT MOPED are designed for shifting control elements by a reversible rotary motion
(e.g. slide valve and other elements) for which they are suitable with their properties. Typical example of using is remote
two-position or multi-position control of elements where tight closure in end positions is required.
The electric actuators are also suitable for automatic regulation in the regime S4 - see Working regime.
2. OPERATING CONDITIONS, OPERATING POSITIONS
Operating conditions
The actuators MODACT MOPED are resistant against influence of operating conditions and external effects of classes
AC1, AD7,AE6, AF2, AG2, AH2, AK2, AL2, AM-2-2, AN2, AP3, BA4 and BC3 according to ČSN 33 2000-5-51 ed. 3.
When the actuator is installed on a free area it is recommended to fit it with a light shelter against direct impact of
atmospheric effects. The shelter should overlap the actuator contour by at least 10 cm at the height of 20 – 30 cm.
When actuators are to be installed in the working environment with temperature below -10 °C and in the environment
with relative humidity above 80 %, it is always necessary to use an anti-condensation heater fitted to all actuators.
The electric actuators can be installed in areas with non-flammable and non-conductive dust, provided that this does not
adversely influence their function. Here, it is necessary to strictly observe ČSN 34 3205. It is recommended to remove dust
as soon as its layer is about 1 mm thick.
Notes:
The area under a shelter means the one where falling of atmospheric precipitations under and angle up to 60° from the
vertical is prevented.
The electric actuator must be installed in a place where cooling air has a free access. Minimum distance from a wall for access
of air is 40 mm. Therefore, the area where the electric actuator is installed must be sufficiently large, clean and ventilated.
Surrounding temperature
Operating temperature for the MODACT MOPED 52 039 is from -25 °C to +60 °C.
Classes of external influences – as extracted from ČSN Standard 33 2000-5-51 ed. 3.
Class:
1) AC1 – above-sea level ≤ 2000 m
2) AD7 – shallow immersion, possible sporadic partial or full coverage
3) AE6 – strong dust formation
4) AF2 – occurrence of corrosive or polluting agents is atmospheric; presence of corrosive pollutants is significant

Service life of actuators
The actuator designed for shut-off valves must be able to perform at least 10,000 working cycles (Close-Open-Close).
The actuator designed for regulation purposes must be able to perform at least 1 million cycles with running time (when the
output shaft is moving) at least 250 hours. Service life in operating hours (h) depends on loading and number of switching
actions. High frequency of switching is not always beneficial for precision of regulation. For reaching the longest possible
faultless period and service life, it is recommended to set frequency of switching to the lowest possible number of switching
actions necessary for the given process. Orientational data of service life derived from the set regulation parameters are shown
in the following table.
Service life of electric actuators for 1 million starts
Service life [h] 830 1 000 2 000 4 000
Number of starts [1/h] Max. number of starts 1200 1 000 500 250

– 3 x 230/400 V, +10 %, -15 %, 50 Hz ±2 %
(or as shown on the motor rating plate)
Protective enclosure
Protective enclosure of actuators – IP 67 according to ČSN EN 60529.
Noise
Level of acoustic pressure A max. 85 dB (A)
Level of acoustic output A max. 95 dB (A)
Tripping torque
Tripping torque is set at the manufacturer according to the customer's requirements within the range given in Table No. 1.
If setting of tripping torque is not required maximum tripping torque of the required type number of the electric actuator is set.
Breakaway torque
Breakaway torque is a calculated value, determined by electric motor’s breakaway torque, actuator's total ratio and
effectiveness. Actuator can produce breakaway torque after run reversing operation for 1 to 2 revolutions of the output
shaft, while torque tripping is interlocked. This may occur either in end position or in any optional intermediate position.
Self-locking
Actuator is self-locking provided that load acts against the motion of the actuator's output shaft. Self-locking function
is provided by a roller lock, which immobilizes actuator’s rotor even in case of manual operation.
With respect to safety regulations, it is unacceptable to apply actuators for operating transport lifting equipment
with possible transport of persons, or for equipment where persons may be present below the lifted load.

Sense of rotation
When looking at the output shaft in the direction towards the control box, the CLOSE direction of rotation is identical with
the clockwise sense.
Working stroke
According to Table No. 1.
Manual control
Manual control is performed directly by a handwheel (without clutch). It can be used even when the electric motor is
running (the resulting motion of the output shaft is determined by the function of the differential gear). When the handwheel is
rotated clockwise the output shaft of the actuator also rotates clockwise (when looking at the shaft towards the control box).
On condition that the valve nut is provided with left-hand thread, the actuator closes the valve.
Torque-limit switches in the actuator are set and work when the actuator is under voltage.
When using the manual control, ie. actuator is controlled mechanically, the torque-limit switches doesn´t work
and the valve can be damaged.
5. ACTUATOR OUTFIT
Position indicator
The actuator can be fitted with a display as an option for electronic system DMS2 ED. Actuator with electronic system
DMS2 is equipped with two-line display.
Anti-condensation heater
Anti-condensation heater is connected to DMS and DMS ED electronic circuit. Switching of the anti-condensation
heater is controlled by a thermostat. From the factory is the switching temperature set to 10 °C. The temperature is
adjustable by adjusting software DMS2. Input power of the anti-condensation heater is 10W / 230V.
6. ELECTRIC PARAMETERS
External electric connection
The electric actuator is equipped with a terminal board for connection to external circuits. This terminal board uses
screw terminals allowing conductors with a maximum cross-section 4 mm2 to be connected. Access to the terminal board is
obtained after removal of the actuator cover. All control circuits of the electric actuator are brought out to the terminal board.
Connecting of actuators with connector – on special request.
Actuator internal wiring
The internal wiring diagrams of the MODACT MOPED, 52 039 actuators with terminal designation are shown in this
Mounting and operating instructions.
Each actuator is provided with its internal wiring diagram on the inner side of the actuator cover. The terminals are marked
on a self-adhesive label attached to a carrying strip under the terminal block.
Isolation resistance
Isolation resistance of electric control circuits against the frame and against each other is min. 20 MΩ. After a dump
test, isolation resistance of control circuits is min. 2 MΩ. See Technical specifications for more details.
Current-carrying capacity and maximum voltage of micro switches
Micro switches maximum voltage is 250 V AC and DC at the following maximum current values:
MO, MZ 250 V AC / 2 A; 250 V DC / 0.2 A
SO, SZ 250 V AC / 2 A; 250 V DC / 0.2 A
PO, PZ 250 V AC / 2 A; 250 V DC / 0.2 A
Micro switches can be used only as single-circuit micro switches. Two voltages of varying values or phases must not be
connected to the terminals of one micro switches.

Actuators are provided with one internal and one external protective terminal serving as protection from electric shock.
Protective terminals are identified with a sign complying with ČSN IEC 417 (34 5555).
If actuator is not provided with over-current protection when purchased, such protection must be provided externally.
7. ELECTRONIC OUTFIT
Electro-mechanical control board is replaced with the electronic system DMS2 or DMS2 ED. Both systems scan
position of the output shaft and torque of the electric actuator by contact-free magnetic sensors. Long service life is
guaranteed for the contact-free sensors that do not get mechanically worn.
The sensor of the output shaft position is absolute and does not require any backup power supply in case supply
voltage is disconnected during operation of the electric actuator. Both systems can be set and monitored by a computer
with controlling program (set parameter can be backed up on a computer) or manually without a computer (for the
electronics DMS2, parameters can be manually set and it can be checked without computer only if the system is equipped
with a display and local control). They contain diagnostic functions - error messages on the display, memory of recent
failures and number of occurrences of respective failures.
The more simple system DMS2 ED substitutes the electro-mechanical board and/or provides for controlling the electric
actuator by input analog signal as in the version Control.
The system DMS2 enables the electric actuator to be used for two-position and three-position regulation or to be
connected to the industrial bus bar Profibus.

by analog input signal.
Function and setting of output relays
The output relays replace end-limit micro-switches; to some extent, function of the output relays differs according to
chosen mode of electronics or it can be selected, preferably by the setting program.
Relé MO, MZ, PO, PZ
In the version Control, the function of relay MO/MZ is same as that of motor relays.
Their operation is controlled by:
- regulation loop (deviation of required and actual position)
- active errors
Any induced active error will change over both relays to a standstill position (coils not energized). In case of errors,
the relays with a function of torque relays (in both versions DMS2 ED and DMS2 ED Control) are also controlled.

Setting program
The setting program is same for communication with the electronics DMS2ED and DMS2. The users' version
can be freely downloaded.
Note: In the window "Parameters“ of the setting program, column "Access“, the word "NO“ designates parameters that
cannot be changed by the user (change of these parameters is blocked).
PROCEDURE OF SETTING PARAMETERS BY MEANS OF PUSH-BUTTONS
For simple programming of required operating parameters, the control unit is fitted with four push-buttons:
MENU, P, O, C and three signal lamps.
Yellow Red Green State
- - - System without feeding
- - lit on Everything OK - working regime (remote, local or switched-off control)
- blinking lit on Error or warning – working regime (remote, local or switched-off control)
lit on - lit on Input or output for setting parameters with push-buttons or setting
parameters by means of PC
blinking - lit on
blinking blinking lit on Setting parameters with push-buttons
blinking blinking lit on
In adjustment, follow the paragraphs “VERIFICATION of APPARATUS FUNCTION And its LOCATION”, “fitting
on VALVE” and “ADJUSTMENT of ACTUATOR with VALVE” of these instructions.
For safety reasons, the system is delivered in the state of induced error of Calibration when the functions are
limited in order to reduce the risk of damage to the actuator by wrong wiring.
Record of position CLOSED, OPEN and AUTOCALIBRATION
– The actuator must be adjusted in such a way that the recorded position would switch off the actuator before it is
switched off by torque. For tight closure, the torque relay for torque Closed is only connected into the control circuit.
The actuator can be shifted either manually or electrically. The actuator in version CONTROL can be started from
menu MOTOR in program DMS2. In this case, the actuator does not react to the set position and can only be stopped
by the torque relay. In controlling from menu MOTOR, no torque may be induced. The torque must be left manually.
If, during adjustment, the torque is reached in the end-limit position, the torque must be left by means of a hand wheel.
– The actuator is set to position Closed and position Closed is stored by long pressing of push-button C (without entering
the Menu).
– The actuator is set to position Open and position Open is stored by long pressing of push-button O.
– The calibration routine is started by means of push-button P (in remote control) that, in the three-position regulation,
will measure actual inertial masses of the system and store them into the memory of the control unit. In the twoposition
regulation, pressing of push-button P only cancels the error of Calibration.
– In recording the end-limit positions, signalling relays and the position transducer are also set.

PROCEDURE OF SETTING PARAMETERS BY PROGRAM DMS2
– Before putting the actuator into operation, it is necessary to set some parameters of the system by means of
the program DMS2 on PC.
– For safety reasons, the system is delivered in the state of an induced error of Calibration when its functions are lim-
ited in order to reduce the risk of damaging the actuator by incorrect connection. When the actuator is controlled by
the program DMS2 its operation is stopped if any torque is induced.
Working torque
– Check and, if necessary, set the value of the working torque 50 – 100 % in the program DMS2.
Record of positions OPEN, CLOSED and AUTOCALIBRATION
The actuator should be adjusted so that the recorded position would stop the actuator before it is switched off by
torque. The actuator is shifted manually or electrically. The actuator in version CONTROL can be started from menu
MOTOR in program DMS2. In this case, the actuator does not respond to the set position and is switched off by torque.
In controlling from menu MOTOR, no torque may be induced. The torque should be left manually.
Record of position CLOSED:
– In the required position, press push-button Z in the program and confirm the approved record.
Main window of setting program Selection of electronics

12
Record of position OPEN:
– In the required position, press push-button O in the program and confirm the approved record.
The recorded values are confirmed by pressing push-button START in program DMS2. For the actuator in version
CONTROL, change over the actuator to remote control and, by pressing push-button START, start the autocalibration. By short
starting of the motor in both directions, the actuator measures inertia and changes over to the regulating regime. Information on
the course of autocalibration is signalized next to push-button START. The autocalibration cannot be started in case the torque
relay is switched off. The torque should be left manually.
Other parameters
Check and, if necessary, change other parameters:
Control signal 4 – 20 mA, 20 – 4 mA, 0 – 20 mA, 20 – 0 mA
Insensitivity 1 – 10 %
Function in case of error open, close, stop, to position
Time of torque blocking in end-limit positions 0 – 20 s
Position of torque blocking in end-limit positions 1 – 10 %
Output of position signal 4 – 20 mA, 20 – 4 mA
Function READY combined error
Note: Signal READY is brought out as the relay contact on the terminal board. If an error or warning state has not
been detected (setting is possible of what should be evaluated as an error or warning) the contact is closed; in
case of an error, warning or if the power supply is electronically cut out the contact is opened.
The state of the relay READY is indicated by the LED diode on the source board.
AUTO-DIAGNOSTICS
DMS2.ED performs continuously its diagnostics and, in case a problem is found, it signalizes warning or error.
Warning or error are signalized by LED, display, and/or relay Ready.
The warning has no influence on the system operation; the error stops the drive.
Assignment or switching-off of the warning and error is set in the window "Warnings and errors" of the setting program
(it is opened by clicking on one of the parameters Warning 1 – 4 or Error 1 – 4 in the window "Parameters").
RESTORING PARAMETERS FROM BACKUP
with the feeding switched off, press push-buttons O and C at the same time. Then, switch on feeding and wait until red
and yellow LED diodes light on. The backup parameters are read.
In DMS2 setting program we will restore the parameters from backup by pressing button "Restore".
Terminal board of actuator with electronics DMS2ED.
If the actuator is of the single-phase version the power supply is connected only to terminals E, N U. The terminals
V, W remain non-connected. If the actuator is of the version "Replacement of electric-mechanical board" with three-phase
electric motor without power relays, the electric motor is connected to a separate terminal board (not shown here).

Memory of number of induced warnings and errors
– For all ascertained warnings and errors, DMS2.ED uses counters of occurrence of these warnings and errors during
operation of the system.
– Values of the counters are stored to the EEPROM memory and are preserved even in case of the power supply fall-out.
– Reading of the counters is possible by means of the program for PC
– Clearing of the counters is possible by means of the program for PC with the level of authorization “SERVICE”.
Memory of recently induced warnings and errors
– DMS2.ED stores three recently induced warnings and errors to the EEPROM memory.
– Recent warnings and errors can be displayed and erased by means of the program for PC.

DMS2
Main features of DMS2:
– Complete control of the actuator operation by two and three-position regulation or connection to an industrial
bus-bar Profibus.
– Well-arranged signalization of operating and service data on a character-type LCD display 2 x 12.
– Auto-diagnostics of error messages on an LCD display, memory of recent failure and number of occurrences
of respective failures.
– Parameter setting by means of PC program or local control in case the actuator is fitted with the local
control.
Basic outfit:
The control unit is a main part of the system DMS2; it includes:
– Micro-computer and memory of parameters
– Position sensors
– 2 signalling LED
– Connectors for connecting torque sensor, boards of relays and two-position inputs, source boards, communi-
cation adapter, LCD display, and local control.
The torque unit provides for scanning torque by a contact-less sensor.
Source unit – two types exist:
DMS2.ZAN for the two-position or three-position control of the actuator by binary signals “Open” and “Close” or by ana-
log signal 0(4) – 20 mA.
DMS2.ZPR for controlling the actuator by the industrial bus Profibus.
Both units include the feeding source for electronics, two relays for controlling the power switches (contactors or
contactless switches) of the electric motor, guarding of sequence of phases (in case the actuator is fed by three-phase
voltage), circuits for connecting the anticondensation heater, and input terminals for connecting the thermo-contact from
the electric motor. The units are fitted with the power terminal board for connecting the power supply. The units are fitted
with a connector for the display and local control.
Unit DMS2ZAN also contains:
– input circuits for the two-position and three-position control of the actuator and terminals for connecting external cont-
rol signals
– input of signal SAFE – information on external failure
– relay – total of five; four (signalling) can be set for reporting of position, torque, or other operation states of the actuator;
the fifth (Ready) is used for reporting of errors, warnings, and other states when the actuator cannot faultlessly perform
its function, and the terminals to which contacts of the relay are connected
– circuits of the feedback current signal – information on position of the actuator output shaft
Unit DMS2.ZPR also contains:
– circuits for communication with the superior control system through the industrial bus Profibus DP, input and output
terminals for connecting the bus, and termination resistors with a switch.
Display unit – two-row display, 2 x 12 alpha-numeric characters
Unit of push-buttons – sensors of push-buttons “open”, “close”, “stop” and the rotary switch “local, remote, stop”.
The actuator can be fitted with contactors or contactless switching of the electric motor; it can be fitted with an
electronic brake.
PROCEDURE OF SETTING PARAMETERS BY PROGRAM DMS2
Before putting the actuator into operation, it is necessary to set some parameters of the system by means of
the program DMS2 on PC.
Warning: For safety reasons (to reduce the risk of damaging the actuator by incorrect connection), the system is deli-
vered in the state of an induced error of Calibration when its functions are limited. When the actuator is controlled by the
program DMS2 its operation is stopped if any torque is induced.
Note: The setting program is same for the electronics DMS2ED. Main window and window Electronics selection – see
figure on page 9.

19
Working torque
– Check and, if necessary, set the value of the working torque 50 – 100 % in the program DMS2.
Tripping in limit positions
– Check and, if necessary, set the way of tripping in limit positions:
– Torque
– Torque + position O
– Torque + position Z
– Torque + position Z+O
Limit positions - working stroke
– Position Z:
– Move to the position Closed manually or by means of the menu Motor in the program DMS2.
– The actuator can only be controlled by means of the program if no torque is induced. The torque must be left manually.
– Press the push-button Z to confirm your consent with the entry.
– Position O:
– Move to the position Open manually or by means of the menu Motor in the program DMS2.
– The actuator can only be controlled by means of the program if no torque is induced. The torque must be left manually.
– Press the push-button O to confirm your consent with the entry.
Auto-calibration
– The auto-calibration can only be started by means of the program if no torque is induced. The torque must be left manually.
– The auto-calibration is started by the push-button Start in the program DMS2.
– Wait until the auto-calibration ends; the information on its course is signalized next to the push-button Start.
Other parameters
Check and, if necessary, change other parameters:
Note: SAFE – input of information on error of an external device can be set so that the actuator would respond as if the
error were its own.

Autodiagnostics
The table List of errors – same as for electronics DMS2 ED (page 12)
Memory of number of induced errors
– For all detected errors, DMS2 uses the counter of occurrence of these errors during operation of the system.
– Values of the counters are stored to the EEPROM memory and are preserved even in case of the power supply fall-
-out.
– Reading and clearing of the counters is possible by means of the program for PC.
Memory of recently induced errors
– DMS2 stores 3 recently induced errors to the memory EEPROM.
– DMS2 provides for displaying the errors by means of the PC program or the switches of the local/ remote control.
– The display in MENU 22 INFORMATION shows ERROR 1, ERROR 2, ERROR 3. ERROR 1 is the latest error.
Setting parameters by means of push-buttons of local control
Signalization of operation regimes by means of diodes LED on the position sensor board:
Red Green State
- - System without feeding
- lit on Everything OK – working regime (remote, local, or switched off control)
blinking lit on Error or warning – working regime (remote, local, or switched off control)
lit on lit on Setting parameters by means of push-buttons or PC
Signalization of operation regimes by means of the display:
The display shows the actuator position in %, the state of local control and/or reaching of torque. In case of an error, blin-
king of this state alternates with number of actual error. In case of more errors, these errors repeat cyclically.
