1. APPLICATION
The MODACT MPSED, MPSPED Konstant electric part-turn ( lever ) actuators operating at a constant speed
are used for remote control and automatic regulation of flaps, louvers and valves. They have been specially
designed for industrial plants. The actuators should not be used for other purposes than those specified, without
prior consultation with the manufacturer.
2. OPERATING CONDITIONS, OPERATING POSITION
Operating conditions
The MODACT MPSED, MPSPED actuators should withstand the effect of operating conditions and external
influences, Classes AC1, AD5, AD7, AE4, AE6, AF2, AG2, AH2, AK2, AL2, AM-2-2, AN2, AP3, BA4, BC3 a BE3
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:
A sheltered location is considered a space where atmospheric precipitations are prevented from falling at an angle
of up to 60° from the vertical.
The location of the electric motor should be such that cooling air has free access to the motor and no heated-up
blown-out air is drawn in the motor again. For air inlet, the minimum distance from the wall is 40 mm. Therefore,
the space in which the motor is located should be sufficiently large, clean and ventilated.
Surrounding temperature
Operating temperature for the MODACT MPSED (MPSED Control) is from -25 °C to +70 °C or from -40 °C to +60 °C.
Operating temperature for the MODACT MPSPED (MPSPED Control) is from -25 °C to +60 °C or from -40 °C to
+60 °C
(except 52 260).
Relative humidity from 10 to 100 % with condensation.

Load factor N/N+R is max. 25 %; the longest working cycle (N+R) is 10 minutes (course of working cycle is
shown in the figure).
The highest number of closing operations in automatic regulation is 1200 cycles per hour.
Mean value of loading torque with load factor 25 % and surrounding temperature +50 °C is not higher than 40 %
of maximum tripping torque Mv.
The highest mean value of loading torque is equal to rated torque of the actuator.
Service life of actuators
The actuator intended for shut-off valves must be able to perform at least 10,000 operating cycles (C - O - C).
The actuator intended for regulating purposes must be able to perform at least 1 million cycles with
operation time
(during which the output shaft is moving) at least 250 hours. Service life in operating hours (h)
depends on load and number of switching. Not always, high frequency of switching influences positively
accuracy of regulation. For attaining the longest possible faultless period and service life, frequency of
switching is recommended to be set to the lowest number of switching necessary for the given process.
Orientation data of service life derived from the set regulation parameters are shown in the following table.

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.
Starting torque
The starting torque of the actuator is a calculated value determined by the starting torque of the electric motor and
the total gear ratio and efficiency of the actuator. After run reversation, the actuator can produce a starting torque for
the duration of 1 to 2 revolutions of the output shaft when torque-limit switching is locked. Torque switching is blocked
only at the end positions. Blocking time is adjustable from 0–20 s.
Self-locking
Self-locking is given by using a worm gear in the countershaft box.
Working stroke
The ranges of working stroke are given in 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 DMS2 and DMS2 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 / 230 V.
Local control
Local control serves for controlling the actuator from the site of its installation. For DMS2 ED electronic system includes
two change-over switches: one with positions “Remote control - Off - Local control”, the other “Open - Stop - Close”.
The first change-over switch can be built-in as two-pole or four-pole. The change-over switches are installed in
a terminal-board box and the control elements on the lid of this terminal-board box. If the actuator is equipped with
DMS2 electronic system local control consists of 3 buttons - “Open”, “Stop”, “Close” and rotary switch “Local,
Remote, Off”.
Dynamic brake
The brake is an optional accessory to the actuators fitted with electronics DMS2 and DMS2 ED Control. As
switching elements are used contactors (mechanical contacts) or SSR (modern contactless switching elements).
After opening the switching element (contactor or SSR), it induces dynamic braking moment in the motor for several
tenths of second. During the rest period of the actuator no braking torque is developed. The brake reduces dramatically
time of the actuator run-down and regulation is thus more precise. The used brakes BR2 are controlled, impulse for
action comes form the control unit. Corresponding variant of the brake is chosen according to the electric motor output
and the type of switching elements.

7
Corresponding variant is chosen according to the electric motor power:
contactors BR2 550 output up to 550 W
BR 2,2 output up to 2,2 kW
SSR BR2 BK 550 output up to 550 W
BR BK 2,2 output up to 2,2 kW
Switching of electric motor
The actuators in variants Control are fitted with built-in reversing contactor combinations or SSR switches.
First variant is assembled from two contactors and second variant from contactless switches.
The combination also includes mechanical blocking that prevents both contactors from being closed
at the same time. This could, for instance, happen in case of wrong connection of jumpers on the terminal
board. The blocking is not dimensioned for long-term action. The over-current relays protects the electric motor
against over-loading and is dimensioned with respect to its output. According to the actuator version, the
contactors are controlled by the regulator, change-over switch of local control or external input. Control voltage
is 230 V / 50 Hz as a standard; it is supplied via contacts of position and/or moment micro-switches. Thus,
these micro-switches need not be led out of the actuator. Contactors have defined service life at least 1 million
cycles.
To extend the service life we recommend using contactless reversing unit with a minimum service life of
3 million cycles. The standard control voltage is 24V DC. It is used for output into 4 kW or 7.5 kW. The unit
consists of semiconductor elements - thyristors.
6. ELECTRIC PARAMETERS
External electric connection
a) Actuator terminal board
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 mm
2
to be connected.
Access to the terminal board is obtained after removal of the terminal box cover. All control circuits of the electric
actuator are brought out to the terminal board. The terminal box is fitted with cable bushings for connecting
the electric actuator. The electric motor is fitted with an independent box with a terminal board and
a bushing.
b) Connector
According to the customer's requirements the MODACT MPSED, MPSPEDJ actuators can be fitted with
the connector to provide for connection of control circuits. This connector uses screw terminals allowing
conductors with a maximum cross-section 4 mm2 to be connected. ZPA Pečky, a.s. also supplies
a counterpart for the cable. In order to connect the cable to this counterpart it is necessary to use special
crimping pliers.
Actuator internal wiring
The internal wiring diagrams of the MODACT MPSED, MPSPED 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 terminal box. 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. Isolation resistance of the electric motor is min. 1.9 MΩ. See
Technical specifications for more details.

The actuators are fitted with one internal and one external protection terminal for ensuring protection against
electric shock injury according to ČSN 33 2000-4-41. One protection terminal is also installed on the electric motor.
The protection terminals are marked according to ČSN EN 60 417-1 and 2 (013760).
7. DESCRIPTION
The actuators consist of the following modules (see Fig 1):
a) Electric motor with gearbox 1
b) Power gear unit with manual control 2, 9
c) Control box with cover 6
d) Lever assembly 40, 8, 15
e) Terminal box 5
a) Electrical motor with gearbox (Fig. 1)
This module consists of a three-phase asynchronous motor and a flanged gear box with worm gear drive and spur
gears whose selection allows different control speeds of the actuator to be obtained. The worm gear drive gives the
whole actuator a self-locking feature.
b) Power gear unit with manual control (Fig. 1)
This module is a central mounting part of the actuator. It consists of a box enlosing a differential planetary gear
unit. When motor drive is used the sun gear of the differential planetary gear unit is actuated by the input spur-
gear drive to which the movement is transmitted from the gearbox of an electric motor. The crown wheel of the
planetary gear unit is fixedly coupled to the worm wheel of the manual worm drive. Provided with a handwheel,
the handwheel worm is axially resilient-mounted by means of two sets of conical disk springs. In the manual
control mode, the sun gear of the planetary gear unit is braked, while the crown wheel which is driven with the
help of the handwheel via the planetary gearing by means of the worm gear drive, actuates a carrier that is fixedly
connected to the output shaft.
The handwheel is provided with a (right-hand threaded) locking screw that should be loosened before manual
control is used. At the end of manual control, the locking screw should be retightened. The planetary gearbox
provides for dependable motor and manual control. The box housing the power gear unit is fitted with three tapped
feet for mounting the actuator.

c) Control box (Fig. 1)
With the actuator in its usual position (axis of the output shaft in horizontal plane), the box is installed on the
actuator side – opposite to the lever. The position gearbox 15 (Fig. 2) is installed in the box on the motherboard of
the control part (Fig. 2, 2a). The modules are mutually and with the terminal board box interconnected with cables
(see the figure).
The control box is covered with the lid 6 (Fig. 1).
To facilitate assembling, the output shaft is realized as sectional. The output end of the shaft is attached directly to
the control board and this assembly is then pushed into the output shaft cavity.
d) Lever assembly (Fig. 1)
The lever assembly consists of lever 40 mounted on the output shaft of the power gear unit and circular flange 8 fitted
on its face with a T-groove in which stops 15 are adjustably mounted to limit the lever movement. The flange and
the stops are fixedly connected to the cast-iron box of the power gear unit.
e) Terminal board box 5 (Fig. 1)
It is connected with the control box by a flange and serves for fitting other parts, control circuits, and terminals
for inlet conductors. The terminal board box can accommodate local control and, in case of the version DMS2,
also a display.
Bushings or the connector are screwed in the terminal board box 5 (Fig. 1).
The terminal board and other components (for instance, connector for service connection of a computer) in the
terminal board box are easily accessible after removing the cover of the terminal board box. Cable bushings are used
for tight passing of the cables into the terminal board box.
Other version of the terminal board box is fitted with a connector for connecting supply voltage and control signals.
The connector counterpart with two bushings is included in the delivery.
8. 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

10
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.

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.
Relay 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.
Relays SZ, SO, READY
For the SO and SZ relays the following functions were added:
Moment O negated: when the set torque is reached in the open direction, the relay is disconnected.
Moment Z negated: When the set torque is reached in the closed direction, the relay is disconnected.
Moment O or Z is negated: When the set torque is reached in the closed or open direction, the relay is disconnected.

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)

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 two-position 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.
– In case the actuator stroke is to be increased and the switching off is set to “from position”, the actuator will
switch off during shifting in position O or 100 %. To further change the position, press C or O, and, while
keeping it depressed, the actuator can be further shifted. After required position is reached, it is stored to
memory by pressing push-button C or O.
Parameters that can be changed by user are set by manufacturer as follows:
1. Tripping torques: 100% or required value (it is not recommended to change the value
without consulting the supplier of the valve, etc.).
2. Relay 3 and relay 4: signalization SZ 1 % and SO 99 % of stroke
3. Time of blocking: 2 – 8 s according to rate of actuator shifting
4. Position of blocking: 5 % of stroke from end-limit positions (it is not recommend to change
the value by more than 10 %)
5. Characteristics of position transducer: closed 4 mA, open 20 mA
6. Relay READY: errors + warning + not remote
In version CONTROL:
1. Setting of control signal: closed 4 mA, open 20 mA
2. Insensitivity of actuator in regulation: 1 % (it is not recommended to set insensitivity higher than 3 %)
3. Response in case of loss of control signal: stop
4. Way of switch off in end-limit positions: torque + PO + PZ
Overview of MENU
BROWSING THROUGH MENU
– The setting regime is entered by pressing and keeping depressed push-button MENU for at least 2 s; LED1
is then lit on.
– Shortly press MENU to select the basic MENU – menu M1 to M8 (LED1 signalizes the menu number); by short
pressing of P, O, C they are entered (LED2 signalizes particular parameter).
– Shortly press P to select required value of the parameter. In case the parameter can be set to several values, they
are changed by short pressing of P (number of blinking of LED2 indicates its value). Keep pressing of P to record
the chosen parameter; the record is confirmed by lighting on of LED2.
– Shortly press MENU to gradually set the required menu and parameters.
– After setting all required parameters, exit the setting menu by pressing and keeping depressed push-button

PROCEDURE of SETTING PARAMETERs by PROGRAM DMS2
– Before starting the actuator, it is necessary to set some parameters of the system by means of program
DMS2 on PC.
– 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 damaging the actuator by wrong wiring. In controlling the actuator from program
DMS2, its run is stopped when any torque is induced.

15
Working torque
– Check and, if necessary, set the value of working torque 50 – 100 % in program DMS2, which you change only
after consultation with the armature manufacturer.
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.
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

Terminal board of the actuator with electronics DMS2ED
If the actuator is of the single-phase version the power supply is connected only to terminals PE, 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).
Note: Signal READY is brought out as contact of the relay on the terminal board. If the state ERROR or
WARNING is not detected (setting can be made of what is to be evaluated as error or warning), the contact is
closed; in case of error, warning, or if feeding of electronics is interrupted, the contact is opened. The state of the
relay READY is indicated by the LED diode on the source board.
AUTODIAGNOSTICS
DMS2 ED performs continuously its diagnostics and, if a problem is detected, it reports warning or error. The warning
or error is signalized by LED of the display and, possibly, by relay Ready. The warning has no effect on operation of the
system, the error stops the actuator.
Assigning or switching off of warnings and errors is set in window “Warning and error” of the setting program (it is
opened by clicking one of parameters Warning 1 – 4 or Error 1 – 4 in window “Parameters”).
The error or warning are reported by opening the relay READY and by blinking of the red LED diode on the control
unit. Particular error is specified by program DMS2 or on the display.
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".

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.
