The Mounting and Operating Instructions specify basic principles for mounting, connection, adjustment, opera-
tion, maintenance, and repairs of electric explosion-proof actuators. A fundamental prerequisite is that assembly,
operation, maintenance, and revisions are performed by skilled technicians qualified for operation and works on
explosion-proof electric devices and the works are supervised by a professionally qualified expert instructed in
a demonstrable way.
1) APPLICATION
The MODACT MOED EEx electric rotary multi-turn actuators are specially intended for controlling devices
by a reversing rotary motion, e.g. slide valves and valves, and, in connection with an appropriate gearbox, also flap or
ball valves, and other devices for which they are suitable due to their properties.
They can be operated in an environment with a danger of explosion of explosive gaseous atmosphere in zone 1
and zone 2 according to ČSN EN 60079-10 (332320). The actuators are designed as a device of group II, category 2G
in compliance with standards ČSN EN 60079-0:2004, ČSN EN 60079-1:2004, and ČSN EN 60079-7:2004 for explo-
sive gaseous atmosphere.
The actuators are marked with a label of protection against explosion and symbols of the group and category
of the device II 2G.
– for surrounding temperature -25 °C to +55 °C: with marking Ex d IIC T4
– for surrounding temperature -50 °C to +55 °C: with marking Ex d IIB T4
Marking of actuators for surrounding temperature -50 °C to +55 °C is with the letter F at the 11th place of the type
number, i.e. 52 120.xxxxEDF. The electronic outfit of the version Ex d IIB T4 should be discussed with the manufacturer.
Nomenclature:
Environment with explosion danger – Environment in which an explosive atmosphere can be created
Explosive gaseous atmosphere –A mixture of flammable substances (in the form of gases, vapours or mist)
with air under atmospheric conditions in which, after initialization, burning
spreads out to non-consumed mixture.
Maximum surface temperature –
The highest temperature created during operation under the most unfavourable
conditions (however within approved limits) on any surface part of the electric
device, which could induce ignition of surrounding atmosphere.
Closure – All walls, doors, covers, cable bushings, shafts, rods, pull-rods, etc. which
contribute to the type of protection against explosion and/or to the level of
protection (IP) of the electric device.
Explosion-proof closure “d” – Type of protection in which the parts capable of causing ignition of
an explosive atmosphere are installed inside the closure; in case of internal
explosion this closure should withstand pressure of the explosion and pre-
vent spreading of the explosion into the surrounding atmosphere.
Zone 1 – A space where probability of occurrence of an explosive atmosphere of
a mixture of flammable substances in the form of gas, vapour or mist with
the air is occasional under normal operation.
Zone 2 – A space where occurrence of an explosive gaseous atmosphere formed of
a mixture of flammable substances in the form of gas, vapour or mist with
the air is improbable under normal operation; however, if this atmosphere is
formed it will only persist for a short period of time.

atmospheric effects.The shelter should overlap the actuator contour by at least 10 cm at the height of 20 – 30 cm.
When the actuators are to be installed in a working environment with temperature below -10 °C and in an 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.

Operating position
Working position of actuators MODACT®MOED EEx actuators with plastic lubricant – any position.
The actuators with plastic lubricant are labelled “Filled: solid grease” on the power box at the side of the hand-wheel.
Actuators with oil charge – position limited only by slope of electric motor axis – max. 15° under the
horizontal level. In this way, reducing of service life of rubber sealing of the electric motor shaft by possible
fragments or impurities from the oil filling is prevented.
When the actuator is assembled with the electric motor above the horizontal plane the oil filling should
be topped up so that reliable lubrication of the motor pinion is ensured.
The actuators with oil filling are not labeled.
3) OPERATION MODE, SERVICE LIFE OF ACTUATORS
Operation mode
According to ČSN EN 60 034-1, the electric actuators can be operated in the S2 load category. The run time at
temperature +50 °C is 10 min, the mean load torque is max. 60 % of the value of the maximum tripping torque Mv.
According to ČSN EN 60 034-1, the electric actuators can also be operated in S4 load category (interrupted
operation with starting-up).
The load factor N/N+R is max. 25 %; the longest operating cycle N+R is 10 min (the course of load is shown
in the picture). The maximum number of switching actions in automatic control mode is 1200 h-1. The mean load
torque with load factor 25 % and ambient temperature of 50 °C shall not exceed 40 % of the maximum tripping
torque Mv.
The highest mean load torque is equal to rated torque of the actuator.
Service life of actuators
Service life of actuators is 6 years, at the least.
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.

4) TECHNICAL DATA
Supply voltage
The actuators have been designed to operate at supply voltage of 3 AC 400 V / 50 Hz. However, they are
available in design variants operating at another three-phase AC supply voltage, upon special request. The supply
voltage of the electric motor should be within the tolerance limits of ±10 % of the rated value and the supply voltage
frequency should be within ±2 % of the rated value. Within this supply voltage range, all parameters are kept
up except the starting torque which varies with the square of the supply voltage deviation from the rated value.
This dependence is directly proportional to the supply voltage variation; no larger supply voltage and frequency
fluctuations are permitted.
Protective enclosure
Protective enclosure of actuators MODACT MOED EEx – IP 55 according to ČSN EN 60 529
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, 2. 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. This can take place in either
end position or in any intermediate position.
Self-locking
The actuator is self-locking provided that the load only acts in the direction against motion of the actuator
output shaft. Self-locking is ensured by a roller arrest immobilizing the electric motor rotor even in the case of
manual control.
In order to observe safety regulations, the actuators cannot be used for driving transportation lifting devices with
possible transport of persons or for installations where persons can stand under 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
The ranges of working stroke are given in Table No. 1 or No. 2.
Rising spindle
In the design variants with connecting dimensions, Shapes A and C, the actuators can be adapted for mounting
to the valve with a rising spindle that projects over the upper end of the actuator output shaft in the end position of the
valve. The space reserved for the rising spindle is clearly shown in the dimensional sketches. The user should mount
a cylindrical guard of the rising spindle instead of the port cover at the control box top, if required. This guard has not
been included in the delivery of the actuator.
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.

5) ACTUATOR OUTFIT
Anti-condensation heater
The actuators are fitted with an anti-condensation heater preventing condensation of water vapour. It is connected
to the AC mains of voltage 230 V.
Local control
Local control serves for controlling the actuator from the site of its installation. It includes two change-over switches:
one with positions “Remote control - Off - Local control”, the other “Open - Stop - Close”.
The former 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.
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 mm2to 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.
Actuator internal wiring
The internal wiring diagrams of the MODACT MOED EEx 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 Mohm. After
a dump test, isolation resistance of control circuits is min. 2 Mohm. Isolation resistance of the electric motor is min.
1.9 Mohm. See Technical specifications for more details.

Protection
The actuators are fitted with one internal and one external protective terminals ensuring protection against electric
shock according to ČSN 33 2000-4-41. One protective terminal is also fitted to the electric motor. The protective
terminals are labelled with a mark according to ČSN EN 60417-1a2 (013760).
7) DESCRIPTION
The electric actuators are designed for direct attachment on the controlled device. (valve etc.). The actua-
tors are connected by means of a flange and a clutch according to ČSN 18 6314. The actuator flanges also
comply with ISO 5210. The following clutches are available for transmission of the output shaft motion to the
valve:

9
Shape A (with adapter), according to ISO 5210 and DIN 3210
Shape B1 (with adapter), according to ISO 5210 (shape B according to DIN 3210)
Shape B3 (without adapter), according to ISO 5210 (shape E according to DIN 3210)
Shape D (without adapter), according to DIN 3210
Shape C (without adapter), according to DIN 3338
The adapters are mounted between the actuator and the valve.
Moreover, the actuators can be delivered with connection according to Russian standards OCT (connection M, A,
Б, В, Г), see the version in table no. 3.
The electric actuator configuration is shown in Fig. 1. The three-phase asynchronous motor 1 drives, via the coun-
tershaft gearing 2, the sun gear of the differential gear unit installed in the actuator supporting box (power gearing) 3.
In the motor control mode, the crown gear of the planet differential unit is held in fixed position by a self-locking
worm gearing. The handwheel 4 connected with the worm allows manual control even when the motor is running. The
output hollow shaft is fix-connected to the driver of the planet gear and passes to the control box -5- where scanning
and control elements of the actuator are installed.
Operation of the torque-limit switching is derived from axial displacement of the “floating worm” of the manual con-
trol unit which is scanned and transferred to the control box by means of a lever. The control box forms an explosion-
proof closure “d” with designation Ex d IIC T4. The control elements are accessible after removing the cover 6
of this box. Access to the terminal box is possible after removing the cover 8.
The terminal board box also includes a firm closure “d” marked Ex d IIC T4. The cable inlets are secured by certi-
fied cable bushings HAWKE, type ICG 623, with a certificate; they can be used within the temperature range from
-60 °C to +80 °C. The bushings of the following sizes are used in the terminal board box:
cable ø
2 pieces ICG 623/B M25x1,5 13,0 – 20,2 mm Both cliental
2 pieces ICG 623/A M20x1,5 11,0 – 14,3 mm
One serves for interconnection with
the electric motor, the other is cliental.
The cable outlet system should meet the requirement of ČSN EN 60079-14 art. 10.3.2.d for direct inlet to the firm
closure of class IIC.
Therefore, in connecting the actuator, the client should provide for a non-explosive sealing (filling-in individual cable
wires) by means of the enclosed two-component filling-in putty according to the instructions.
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.

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 regulati-
on, 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.

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.
Working torque
– Check and, if necessary, set the value of working torque 50 – 100 % in 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.

Terminal board of 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).
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
Note: Signal READY is brought out as contact of the relay on the terminal board. If the state ERROR or WAR-
NING is not detected (setting can be made of what is to be evaluated as error or warning), the contact is clo-
sed; 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.

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 properties of DMS2:
–
Complete control of the actuator run of the two- and three-position regulation or connection to the industrial bus Profibus.
– Synoptic signalization of operation and service data on the character LCD display 2 x 12.
– Autodiagnostics of error reports on the LCD display, memory of recent failures and number of occurrences of
respective failures.
– Setting of parameters by the PC program and by local control provided that the actuator is fitted with local control.
Basic outfit:
The control unit is the main part of the system DMS2; it comprises:
– Microcomputer and memory of parameters
– Position sensors
– 2 signalling LED
– Connectors for connecting the torque sensor, relay board, and two-position inputs, source board, communication
adapter, LCD display, and local control
Torque unit provides for scanning torque by the contactless 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
analog 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
control 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 fault-
lessly 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 pro-
gram DMS2 on PC.
Before adjustment, check the actuator according to the paragraph ASSEMBLing And putting the ACTUATOR into operation.
Warning:
For safety reasons (reduced risk of damage to the actuator by wrong wiring), the system is delivered in the state of
the induced error of CALIBRATION when the functions are limited and, during controlling the actuator from program
DMS2, its run is stopped if any torque is induced.
Note:
The setting program is the same for electronics DMS2 ED. See the figure on page 14 for the main window and the
window of Selection of electronics.
