1. APPLICATION
Series MODACT MONJ, MON, MOP actuators have been specially designed for adjustment of fittings and other
devices for which they are suitable due to their properties and reversing rotary motion in particular. These actuators can
be usedin remote control circuits. When fitted with a current transmitter, they can be used even in automatic control
circuits operating in duty S4 - 25 %; 1,200 h-1.
2. OPERATING CONDITIONS
The MODACT MONJ, MON, MOP actuators should withstand the effect of operating conditions and external
influences, Classes AA7, AB7, AC1, AD5, AE5, AF2, AG2, AH2, AK2, AL2, AM2, AN2, AP3, BA3, BP3 and BC3,
according to ČSN Standard 33 2000-3 (mod. IEC 364-3:1993).
If the actuator is to be installed in the open-air space it should be provided with light roofing for protection against
the effect of direct solar radiation.
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.
If the actuator is used at a location with an ambient temperature under -10 °C and/or relative humidity above 80 %,
at a sheltered location, or in the tropical atmosphere, the anti-condensation heater which has been built in all actuators,
should be always used. One or two heater elements should be connected, as required.
Installation of the actuators at a location with incombustible and non-conducting dust is possible only if this has
no adverse effect on their function. It is advisable to remove dust whenever the layer of dust becomes as thick as
about 1 mm.
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.
Classes of external influences
Basic characteristics - as extracted from ČSN Standard 33 2000-3 (mod. IEC 364-3:1993).
1) AA7 – Combined action of surrounding temperature from -25 °C to +70 °C (actuators with plastic lubricant) or
from -25 °C to +55 °C (actuators with oil charge) and relative humidity higher than 10 %.
2) AB7 – Ambient temperature to Point 1); minimum relative humidity 10%, maximum relative humidity 100% with
condensation
3) AC1 – Altitude ≤ 2,000 m above sea level
4) AD5 – Splashing water in all directions
5) AE5 – Small dust content of air; mean layers of dust; daily dust fall more than 35 mg/m2, but not exceeding
350 mg/m2
6) AF2 – Corroding atmosphere and pollutants; the presence of corroding pollutants is significant.
7) AG2 – Average mechanical stress; in current industrial plants
8) AH2 – Medium vibrations; in current industrial plants
9) AK2 – Serious risk of growth of vegetation and moulds
10) AL2 – Serious danger of the occurance of animals (insects, birds, small animals)
11) AM2 – Harmful effect of escaping vagabond currents
12) AN2 – Medium solar radiation with intensities > 500 W/m2and ≤ 700 W/m2
13) AP3 – Medium seismic effects; acceleration > 300 Gal ≤ 600 Gal
14) BA4 – Personal abilities; instructed people
15) BC3 – Frequent contact with the earth potential; persons coming frequently into contat with „live“ parts or
standing on a conducting base
Operating position
Working position of actuators MODACT®: actuators with plastic lubricant - any position; 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.

3. OPERATION MODE
According to ČSN EN 60 034-1, actuators can be operated in S2 load category. The operation time at +50 °C shall
be 10 minutes, the mean load torque value shall be below or equal to 60 per cent of the maximum switch off moment
(Mv). According to ČSN EN 60 034-1, the actuators can also be operated in the S4 mode (interrupted operation with
acceleration intervals). The load factor N/N+R shall be maximum 25 per cent, the longest operation cycle N + R is
10 minutes (the course of load is shown in the picture). The maximum number of switching actions in automatic control
mode is 1200 actions per hour. The average mean load torque at load factor of 25 per cent and 50 °C shall not exceed
40 per cent of the maximum tripping torque (Mv).
The average mean load torque shall not exceed the nominal 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.

Electric connection
Electric connection of the actuator can be made either on the terminal boards or with a connector.
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 2.5 mm2to be connected. Access to the terminal board is ob-
tained 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 inde-
pendent box with a terminal board and a bushing. Alternatively, the electric actuators can be supplied with a push-on cable
connection (HARTING connector) - see the table of design variants.
Connector
According to the customer's requirements the MODACT MONJ, MON, MOP actuators can be fitted with
the connector to provide for connection of control circuits. 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 (supplied by Company
on Order No. 0999 000 0021; e-mail: [email protected]).
5. DESCRIPTION
In respect of their basic connecting dimensions, the actuators have been engineered for direct mounting to
the fitting. The connection of the actuator to the fitting is provided by a flange, according to ČSN 18 6314 (complying
with ISO 5210). For transmission of the output shaft motion of the actuator to the fitting, the actuator is provided with
a Shape C or D coupling to ČSN 18 6314 (complying with DIN 3338) or a Shape E coupling to ČSN 18 6314 (B3,
according to ISO 5210). When adapters are used (which can be supplied with the equipment), the connecting
dimensions, Shape A or B1, to ČSN 18 6314 (complying with ISO 5210) can be obtained. These adapters are mounted
between the actuator and the fitting.
The actuator configuration is shown in Fig 1. The three-phase asynchronous motor -1- drives via countershaft gearing
-2- the sun gear of differential gear unit -2- which is enclosed in the supporting actuator box (power gear transmission) -3.
In the mechanical power control mode, the crown gear of the planet differential unit is held in a steady position by a self-
locking worm gear drive. The handwheel -4-, which is connected with the worm, allows manual control to be accomplished
even during motor operation. The output hollow shaft is fixably coupled to the planet-gear carrier. The output shaft is
extended to the control box -5- in which all control devices of the actua-tor have been concentrated, including position-
limit, signalling and torque-limit switches, a resistance or current position transmitter and the anti-condensation heater.
The operation of the position-limit and signalling switches is derived from output shaft rotation via mechanisms.
The operation of the torque-limit switches is derived from the axial displacement of the „floating“ worm of the manual
control unit which is sensed and transferred to the control box by means of a lever. All controls are accessible after
removal of cover -6- of the control box. Access to the terminal box -7- is obtained after removal of cover -8-. Cable
inlets are secured by cable bushings, Size P16 (or P21 and P16 in the design variant with connector). The electric
motor has its own terminal board -10- with a cable leadthrough. The position of the output shaft can be read on the
position indicator -11-. The individual operating functions of the actuator, e.g., torque-limit switching, position-limit
switching, auxiliary signalling, remote position indication (position transmitter), are provided by mechanical groups
(units). The latter are accommodated on the control board enclosed in the control box, as shown in Fig. 2, 2a.

Local control unit
Local control serves for controlling the actuators from the site of their installation. It consists of two selector
switches: one with positions "Remote control - Off - Local control", the other with positions "Opens - Stop - Closes".
If required by the customer, the actuator can be fitted with a blinker that produces electrical pulses during output
shaft rotation. For the blinker, no power supply has been built in the actuator.
Description and function of control units
a) Torque-limit switching
As shown in Fig.3, the torque-limit switching unit forms an independent assembly group consisting of the base
plate -19- which carries microswitches -20-, while at the same time providing for bearings of the torque control shaft
-22- and the locking shaft -29-.
The torque control shaft transmits movements of the floating worm from the power transmission gear tothe CLOSE
torque-limit microswitch (MZ) or the OPEN torque-limit microswitch (MO) by means of segments -23- or -24-
and levers -45- or -46-. The amount of limit-switching torque can be adjusted by the segments being turned with
respect to the tripping levers.
For readjusting the amount of the tripping torque outside the factory, the segments -23- are provided with a scale
on which the points of adjusting the maximum and minimum torques have been graduated individually for each
actuator, the adjusted torque being indicated by slots in the segments -27- and -28-. However, the numbers on
the scale provide no direct indication of the tripping torque adjustment, but the scale divisions serve only for a more
accurate division of the band between the points of maximum and minimum tripping torque and thus for more accurate
adjustment of the torque outside the factory in a location where no loading stand is available. The segment -23- is
designed for the OPEN direction, whereas the segment -24- is designed for the CLOSE direction.
The torque control unit is also fitted with a locking mechanism. On operation of the torque limiting switch, this
mechanism locks this switch and thereby precludes the switch from being reclosed and thus prevents actuator pulsing.
Moreover, the locking mechanism prevents the torque-limit switch from opening after reversal of the actuator and thus
makes possible full utilization of the starting torque of the actuator. The locking mechanism acts in either direction of
the output shaft motion of the actuator in the end positions as well as in the intermediate positionfor the duration of 1 to
2 revolutions of the output shaft after reversal thereof. With the output shaft of the actuator loaded at a reversed torque,
the torque control shaft -22- and thus the segments -23- and -24- turn by a slight amount. This displacement is

transmitted to the tripping lever -45- or -46-. When the torque on the output shaft of the actuator reaches the value to
which the torque-limit switching unit has been adjusted, the tripping lever depresses the button of the corresponding
microswitch so that the electric motor is disconnected from the mains, thus stopping the actuator.
Adjusting procedure of the torque-limit switching unit
To adjust a different tripping torque from that adjusted at the factory, the procedure is the following: Loosen the lock
nut -44- (see Fig.3) and then the lock screw -25- (for the CLOSE direction) or -26- (for the OPEN direction). Place
a screwdriver in the slot of the upper segment -23- or -24- and turn the segment till the slot in the segment -27- or -28-
tallies with the respective scale graduation. This scale division can be determined so that the difference (in Nm) between
the maximum and the minimum adjustable torques is divided by the number of divisions between the marks of the
minimum and maximum torques. In this way, the amount of tripping torque (in Nm) per scale division is obtained, making
it possible to determine by interpolation the scale division with which the slot in the segment -27- or -28- should tally.
The red division line nearer to number 10 marks the point of adjustment of the maximum tripping torque, whereas another
division line shows the point of adjustment of the minimum tripping torque. The torque control unit should never be
adjusted so that the slot in the lower segment is outside the zone marked by the colour scale division lines.
After adjustment of the tripping torque, retighten the lock screw -25- or -26- and the lock nut -44-.
b) Signalling unit - Fig.4.
This unit transmits an electrical signal to indicate the position of the output shaft of the actuator, drive of the unit being
provided via gear wheel -38- by the output shaft through a multistage gearbox to the cams -30- and -31- which control
the OPEN signalling microswitch -36- (SO) and the CLOSE signalling microswitch -37- (SZ). The instant of operation of
the signalling switches can be selected at any point of the working stroke of the actuator except the narrow band about
the end positions. (The signalling switch should close before the position-limit switch while the output shaft is still moving).
The upper cam -37- operates in the CLOSE direction, whilst the lower cam -36- operates in the OPEN direction.
Designed as an independent unit, the signalling unit shown in Fig.4 has been assembled on the support -39- under
which there are gears arranged as shown in the kinematic diagram of the Fig.5. This gearing has been assembled so that
the adjusting wheel K3 can be moved to different levels (I, II, III, IV, V) after loosening of the lock screw -47-. In this way,
the ranges of adjustment of the signalling switches and the transmitter can be changed, depending on the working stroke
of the actuator. Fig.5 is a table showing the ranges of adjustment for the individual positions of the adjusting wheel K3.
Adjustment of the signalling unit
If the ranges of adjustment of the signalling switches and the transmitter are required to be changedthe position of
adjusting wheel K3 should be changed. For adjustment of the wheel K3, the signalling unit should be withdrawn from
the control box (which is possible due to a sufficient length of lead-in wiresof the microswitches). This can be done
after removal of the 4 screws -66- (Fig.2) used for mounting the unitonto the base plate. After the signalling unit has
been adjusted to the required range it should be brought back into its original position. Before retightening the screws
-66-, the correct meshing of gears K1 and K2 should be checked (see Fig.5). Put on at the lower end of the camshaft

-48- (Fig.5) is the pinion -49- (Fig.5) which is connected to the shaft -46- by an adjustable friction clutch. On this pinion,
the motion required for driving the resistance or current transmitter is sensed. The arrangement of cams
and microswitches of the signalling unit is shown in Fig.4. Shoulders of the cams -30- deflect the levers -34- and -35-,
which in turn control the microswitches -36- (SO) and -37- (SZ). When adjusting the signalling and position-limit
switches and the transmitter, the output shaft of the actuator should be moved to the position in which changing-over
of the microswitches should take place or the required position of the transmitter should be reached.
When adjusting the signalling switches, the following procedure should be used: First, loosen the screws -32-
(for SZ) or -33- (for SO), as shown in Fig.4. Then, turn the cam -30- or -31- in the direction of the arrowhead, i.e.,
anticlockwise for the CLOSE signalling microswitch (SZ) and clockwise for the OPEN signalling microswitch (SO), till
the microswitch closes. In this position, hold the cams and retighten the lock screws.
Caution!
After any manipulation of the lock screws in the control section of the actuator, these screws should be secured
against loosening due to vibrations by a drop of quick-drying varnish. If the screws have secured previously in this way
then, during adjustment, varnish residue should be removed and the surface should be properly cleaned.
c) Adjusting mechanism of resistance transmitter - Fig. 6
This mechanism consists of 2 geared rockers -51- and -55- on which spring -52- is hung. A rail with pins -53- provides for
mutual sliding movements of the two rockers. This group is rotatably mounted on pin -54-. The whole mechanism is mounted
onto the basic control plate -67- (see Fig.2). The geared rockers are in mesh with pinion -43- of the transmitter (Fig.7) or pinion
-49- (Fig.5). Then, the position of pin -54- determines the gear ratio of the adjusting mechanism, i.e., the angle of positioning
the transmitter and the local position indicator is always 160° for different values of working stroke of the actuator and thus for
different amounts of displacement of the camshaft in the signalling unit. This ensure that, at any working stroke, the rated
value of the transmitter signal, i.e., 100 ohms, is always available.
d) Position transmitters
Resistance transmitter, including position indicator - Fig.7
The heart of this unit is a resistance transmitter -52- whose rated value is that of the resistance signal of 100 ohms.
The transmitter has a shaft which has been brought out on both sides. Put on the shaft at the lower end, the pinion -43- has
been arranged to slip on the shaft in either end position of the transmitter, a feature that is extremely suitable for adjusting
the unit. At the upper end of the transmitter shaft, the position indicator -40- is mounted by a screw -41- so that it can be
adjusted with respect to the inspection hole in the control box cover
.
Adjustment of resistance transmitter and position indicator
For positioning of the transmitter, the procedure is the following: In the CLOSE position of the output shaft, press down
the geared rocker -51- (Fig.8) to move it towards the transmitter out of engagement with the pinion -49- (Fig.5). Then, turn the
rocker clockwise up to the stop formed by a column under the signalling unit. Finally, bring the rocker into engagement with
the pinion -49-, whereupon the pointer of the transmitter should indicate 0°. If this is not the case, withdraw the rocker -51-
from the stop and depress the rocker -55- to release the transmitter pinion. Set thetransmitter pointer near the transmitter
scale division line 0° so that, after bringing the rocker -55- into engagement with the transmitter pinion, their teeth fit into one
another correctly. This can be checked by carefully turning the transmitter shaft. Then, throw the rocker -51- out of
engagement and move it up to the stop, exerting an increased force. (After the transmitter pointer has been set to 0°

the pinion starts slipping). Bring the rocker -51- again into engagement with the pinion -49- (Fig.5). In this position, the oval
holes in the geared rockers are parallel with the oval hole in the basic control plate -67- (Fig.2). Thus, the trasmitter has been
adjusted for the CLOSE position. Then, loosen the screw -64- (Fig.8), move the adjusting lever towards the transmitter up to
the stop and retighten the screw -64-.
Bring the actuator into the OPEN position, the transmitter pointer being set to a position between 0° and 160°. Loosen
the screw -64- and turn the adjusting lever -65- anticlockwise till the transmitter pointer does not tally with the scale line 160°.
Then, retighten the screw -64- and secure it against loosening by a drop of quick-drying varnish.In this way, the transmitter
has been adjusted for the OPEN position.

The position indicator is mounted on the shaft of resistance transmitter -42- (Fig.7) by a screw -41-. Loosen this
screw and, in the OPEN position, turn the indicator so that the division line 100 on its scale tallies with the red point on
the sight glass in the control box cover. Finally, retighten the screw -41- and secure it by a drop of quick-drying varnish.
CPT 1/A current position transmitter - adjustment of the transmitter
First, the adjustment of suitable transmission from the output shaft of the actuator to the transmitter shaft should be
effected, according to the required working stroke of the actuator (Table on the page 12).
This adjustment is performed by means of adjusting gear K3 in the gearbox of the signalling unit, according to Mounting
Instructions, Page 8, Point b).
Then, the required gear of the pair of gears fitted on the transmitter shaft should be brought into engagement.
The gear of a smaller diameter is designated A, whereas the larger gear is designated B.
Adjustment is carried out by two-hole oval shim plates being moved to a position under or above the transmitter support
(with gear A or B in mesh, respectively). This should be done in the position in which the transmitter support is at a maximum
distance from the gearbox.
Then, the fixing screws of the transmitter support are slightly tightened so that the transmitter support can be moved to
such a position that gear A or B is in mesh with the driving gear. In this position, check the gear meshing and adjust the double
gear in height with respect to the driving gear by means of shims on the transmitter shaft, if required.To prevent the transmitter
shaft from being stressed in the direction at right angles to its axis, there should be a slight clearance between gear A or B and
the driving gear. Then, tighten the fixing screws of the transmitter support properly and secure them with a drop of varnish.
The velocity stage of gears K3, A and B is selected, according to the accompanying table. When the required working
stroke lies in an area covered by the two bands it is advisable to choose the lower band.
After adjustment of a suitable speed gear-change stage, the current transmitter should be adjusted by the following
procedure:

Caution!
The CPT 1/A transmitter should be connected only after the supply voltage has been checked. The transmitter outlets should not
be connected to the actuator frame, neither should they be earthed, even accidentally.
1) Before the supply voltage is checked the transmitter should be disconnected from the AC mains. At the actuator terminals
to which the transmitter is connected, the voltage can be best measured by a digital voltmeter withan input resistance of
at least 1 Mohm. This voltage should be within the range of 18 to 25 Vdc, but should not exceed 30 V since otherwise
the transmitter might be damaged. Then, connect the transmitter so that the positive terminal of the power supply is
connected to the „plus“ pole of the transmitter, i.e., to the pin provided with a red insulator (r)+ (nearer to the transmitter
centre), and the terminal with a white coating (extended to terminal -52- or H) to the „minus“ pole of the transmitter (white
insulator). In the la-test design variant, the red conductor is „plus“ and the black conductor is „minus“.
2) Connect temporarily a milliammeter, preferentially a digital instrument with an accuracy of at least 0.5% in series with
the transmitter. Bring the output shaft into the CLOSE position. In this case, the signal value should decrease. If this is not
the case, turn the output shaft in the CLOSE direction till the signal starts decreasing and the output shaft reaches
the CLOSE position.
Then, loosen the screws of the transmitter shim plates so that the whole transmitter can be turned to set a current
of 4 mA. Retighten the screws of the transmitter shims. Subsequently, adjust the actuator output shaft to the OPEN
position. Set the current to 20 mA by the trimming resistor fitted on the transmitter face (nearer to the edge).
The trimmer has 12 turns, but no stops. Thus, it cannot be damaged.
If a considerable correction of 20 mA current is required the 4 mA and 20 mA setting procedure should be repeated.
Then, disconnect the milliammeter. Avoid turning the screw situated nearer to the middle and secured by a dropof
varnish. Retighten the fixing screws of the transmitter shim plates and secured them with a drop of varnish.
On completion of the adjusting procedure, check the terminal voltage of the transmitter by a voltmeter. This voltage
should be within the range of 9 to 16 V with 20 mA current.
Note:
The transmitter characteristic has two branches: A descending one and an ascending one with respect to
the CLOSE position (Z).
Setting of current position transmitter CPT1.
Before starting setting the current transmitter it is necessary to set the end-limit positions (torque or position switches) of
the actuator and connect them into the tripping circuit of the electric motor. In case of an external source of feeding voltage,
verification must be carried out that it does not exceed the maximum value 30 V DC (limit value when CPT1 is still not
damaged). Recommended value is 18 – 28 V DC.
Positive pole of the source is connected to the positive pole of the
transmitter CPT1; a milli-ammeter of precision at least 0.5 % connected into
the circuit. The current loop must be earthed in one point. The figure does not
show the earthing that can be made at any point of the circuit.
1. Shift the output shaft into the position Closed. During closing, the current
signal value should decrease. If it increases release the transmitter body
and, by turning of about 180°, shift to the descending part of the
outputcharacteristics. Set 4 mA by fine turning. Tighten the shim plates to
secure the transmitter against spontaneousturning.
2. Shift the output shaft to the position Open and set 20 mA using a potentio-
meter on the transmitter body. The potentiometer has a range of 12 revo-
lutions and it has no stops so that it cannot be damaged by furtherturning.
3. Once again verify the current value in the position Closed. If it has changed
too much repeat the points 1. and 2. If the required corrections are large this procedure should be repeated several times.
After the setting, securethe transmitter against turning and drip the screws with varnish.
4. Use a voltmeter to check the voltage on the CPT1 terminals. In order to keep linearity of the output signal
the voltage must not drop below 9 V, not even with off-take 20 mA. If this condition is not met it is necessary to increase
the feeding voltage (within the range of recommend values) or to decrease total resistance of the current loop R.
Setting of current position transmitter DCPT.
1. Set of end-limit positions
Before starting the setting, verification must be carried out that the end-limit positions are within the range
60° – 340° of revolution DCPT. Otherwise, after setting, an error arises (LED 2x).
1.1. Position “4 mA”
Set the drive into the required position and press the push-button “4” until LED blinks (about 2 s).
12

13
1.2. Position “20 mA”
Set the drive into the required position and press the push-button “20” until LED blinks (about 2 s).
2. Setting of sense of rotation
The sense of rotation is specified by viewing from the side of the panel DCPT.
2.1. Rotating anti-clockwise
Press the push-button “20”, then the push-button “4” and keep them depressed until LED blinks.
2.2. Rotating clockwise
Press the push-button “4”, then the push-button “20” and keep them depressed until LED blinks.
When the sense of rotation is changed the end-limit positions “4 mA” and “20 mA” remain valid but the working
range (track DCPT) between these points is changed to a complement of the original working range. In this way,
the permitted working range can be exceeded (LED 2x) – it can be smaller than 60°.
3. Error messages
In case of an error the diode LED blinks an error code:
1x
Sensor position out of working range
2x Working range incorrectly set
3x Off the tolerance level of magnetic field
4x Wrong parameters in EEPROM
5x Wrong parameters in RAM
4. Calibration of currents 4 mA and 20 mA.
On switching-on the power supply, keep the push-buttons “4” and “20” depressed and release them after a single
blink of LED. In this way the option menu 4.1 Calibration of current 4 mA is entered.
4.1. Calibration of current 4 mA
Connect the ammeter to testing terminals. Press the push-button “20”. Keep depressed the push-button to evoke
the auto-repeat of current decrease. Release the push-button to make record of the present value.
4.2. Calibration of current 20 mA
Connect the ammeter to testing terminals. Press the push-button “4”. Keep depressed the push-button to evoke
the auto-repeat of current increase. Release the push-button to make record of the present value.
4.3. Switching-over between option of calibration 4 mA and 20 mA
Entry of option of calibration 4 mA:
Press the push-button “4”, then the push-button “20” and keep them depressed until LED blinks.
Entry of option of calibration 20 mA:
Press the push-button “20”, then the push-button “4” and keep them depressed until LED blinks.
5. Record of standard parameters
On switching-on the power supply, keep the push-buttons “4” and “20” depressed and release them after a double
blink of LED.
ATTENTION! With this record, the transmitter calibration is also overwritten and, therefore, it must be repeated!!

Parameter setting
e) Position-limit switching unit -16- (Fig.9)
This unit causes the CLOSE or OPEN position-limit switch (PZ or PO) to open when the preadjusted RPMof the output
shaft are reached, the rotary motion of the unit being derived from that of the output shaft by means of the drive wheel -62-.
This wheel is rotated step by step by gear wheels driving cam -57- (-60-). Turning of the cam up to the lever of
the CLOSE or OPEN position-limit switch (PZ or PO) causes the switches to change over.
Handling and setting
The unit can be adjusted within the range shown in Tab.1. The adjusting procedure is the following:
1) After attachment of the actuator to a fitting, bring the fitting into the CLOSE position by means of the actuator.
2) In this position, depress the tripping rod -58- in the vertical direction and then rotate it through an angle of 90°
to the left or right.
3) Turn the regulating screw -56- in the direction of arrowhead designated „Z“ (CLOSE) till the cam -57- depresses
the spring of microswitch -63- (PZ).
4) Rotate the tripping rod -58- at an angle of 90°. As a result, the rod should shift out again. If this is not the case, turn
the screw -56- or -59- by a small amount.
5) Readjust the fitting to the OPEN position by the required number of revolutions, making use of the actuator.
6) Apply pressure on the tripping rod -58- again in the vertical direction and position it at an angle of 90° on either side.
7) Turn the regulating screw -59- in the direction of arrowhead designated „O“ (OPEN) till the cam -60- depresses
the spring of microswitch -61- (PO).
Position "4 mA“
Set the actuator to required position (usually
Closed) and keep the push-button 4 depressed
until LED blinks.
Position "20 mA“
Set the actuator to a required position (usually
Open) and keep the push-button 20 depressed
until LED blinks.

8) Rotate the tripping rod -58- at an angle of 90°. As a result, the rod should shift out again. If this is not the case, turn
the screw -59- or -56- by a small amount.
Note:
Turning the regulating screw -56- or -59- should be stopped at the instant of change-over.
If the cams are in the position shown in Fig.9 before they are adjusted, or the cam has already pressed down
the button of the microswitch, the following procedure is used to advantage:
With the tripping rod -58- depressed and positioned, turn the adjusting screw -56- or -59- anticlockwise till the cam
withdraws at its peak from the microswitch lever towards the adjusting screw and the microswitch changes over
(which can be checked by a suitable indicating tester). Then, move the cam peak back up to the microswitch lever by
turning the adjusting screw -56- or -59- backwards in the direction of the arrowhead till the microswitch opens again
(with its button depressed). Thus, the adjusting procedure of the microswitch has been completed. Finally, shift out the
tripping rod -58-, as described above.
Manual control
The actuator outlet shaft can also be reset manually by means of a hand wheel. By turning the hand wheel clock
-wise, the valve is closed (left thread in the valve is assumed). Before starting the manual control, the lock screw (Fig.1)
should be loosened so that the hand wheel can turn freely. After resetting the outlet shaft to the desired position,
the lock screw should be again tightened to the nearest of six holes in the locking flange.
6. PACKING AND STORING
For inland freight, the actuators are unpacked. However, they should be transported by covered conveyances or in
transport containers.
For delivery abroad, the actuators should be packed, the type and design of package being adapted to the transport
conditions and the distance of the place of destination. Upon receipt of the actuator from the factory, it is essential to
check that no damage was caused during transport and to compare the data on the actuator rating plates with those
contained in the order and accompanying documentation. Any discrepancy, defect or damage should be immediately
reported to the supplier.
When the unpacked actuator is not immediately installed it should be stored at a dust-free location with
a temperature within the range of - 25 °C to + 50 °C and relative humidity up to 80 % where there are neither aggressive
gases nor vapours and which is secured against the harmful effects of climatic conditions. If the actuator is to be
stored for a longer period than 3 years then, prior to commissioning, oil refilling should be made. Any manipulation of
the equipment at a temperature below - 25 °C is forbidden. Storing the actuator out of doors or at a location that is not
protected against the effects of rain, snow or ice accretion should be avoided. Before putting the actuator into
operation, slush should be removed. When unpacked actuators are to be stored longer than 3 months it is advisable to
place a bag with silica gel or another suitable dessicant in the terminal box.
7. CHECKING OF THE INSTRUMENT FUNCTION AND ITS LOCATION
Prior to installation, make sure that the actuator was not damaged during storing. A functional check of
the electric-motor can be made so that it is connected to the AC mains via a circuit breaker and started for short-time
operation. In this case, it is sufficient to make sure that the electric motor starts and turns the output shaft. The actuator
should be installed so as to obtain easy access to the handwheel, the terminal box and the control box. It is also
imperative to check that the installation complies with the Clause „Operating Conditions“. If another method
of installation is required due to local conditions, please consult the manufacturer.
8. ATTACHMENT TO A FITTING
Place the actuator on the fitting so that the output shaft fits dependably in the coupling thereof. Attach the actuator
to the fitting by 4 (8) screws and check the attachment by rotating the handwheel. Remove the terminal box cover
and wire the actuator, according to the internal and external circuit layouts.
For handling the actuator during assembly with the fitting, make use of the three suspension lugs with which
the actuator is provided. In no case, these lugs can be used for suspension of the actuator with the fitting.

16
9. ADJUSTMENT OF THE ACTUATOR WITH A FITTING
After placing the actuator on the fitting and checking its attachment, the following adjusting procedure should be used:
1) Bring the actuator into an intermediate position by the hand.
2) Connect the actuator to the AC mains and check the correct sense of output shaft rotation by starting the actuator
midway between the dead points of the working stroke for a short time. When viewing into the control box,
the output shaft should rotate clockwise in the CLOSE direction.
3)
Move the actuator electrically near the CLOSE position and complete the adjusting operation by settingthe actuator
precisely to the CLOSE position, employing the handwheel. In this position, set the position-limit switching unit (CLOSE
position-limit microswitch PZ) and the resistance or current transmitter, accordingto Points 5e and 5d, respectively.
4) Bring the output shaft into the position in which the CLOSE signalling switch (SZ) should change over. Adjustment
of the CLOSE signalling switch (SZ) should be made, according to Point 5b.
5) Move the output shaft of the actuator by the required number of revolutions and set the OPEN position-limit switch
(PO) and the resistance transmitter, according to Point 5e and 5d, respectively. The position-limit and signalling
switches as well as the position transmitter should be checked repeatedly.
6) Bring the output shaft into the position in which the OPEN signalling switch (SO) should change over. Adjust
the OPEN signalling switches (SO), according to Point 5b.
Caution!
The cover of the control box should be removed so that it is displaced in the direction of extended axis of the output
shaft of the actuator, taking care to avoid any damage to the position indicator. When mounting the fitting on
the pipeline, the fitting should be brought into the midway position by means of the handwheel. By starting the electric
motor for a short time, check that the actuator rotates in the correct direction. If this is not the case, the two phase
conductors should be mutually reversed on the terminal board.
10. OPERATION AND MAINTENANCE
Depending on the operating conditions, the operation of rotary actuators usually involves only the transmission of
pulses, as required for the individual functions. In the event of a power supply failure, readjust the controlled device by
the handwheel. If the actuator has been connected in the circuit of automatic equipment (which does not imply
the control mode) it is advisable that manual remote control units are connected in the circuit so that the actuator can
be controlled even if a failure of the automatic equipment occurs.
It is the operator’s duty to ensure that the actuator is given the prescribed maintenance attention and is protected
against the harmful effects of ambient and climatic conditions not included in the Clause „ Operating conditions“.
Within half a year at the latest from putting the actuator into operation and then at least once a year, it is necessary to
properly tighten the bolts connecting the valve with the actuator. The bolts are to be tightened in a cross-wise manner.
Lubrication
The actuators are lubricated with plastic consistent lubricants or gearbox oil PP80.
Actuators with plastic lubricant
The types of lubricant and amounts are listed in the table.
Lubricants in the drive units supplied are designed to last the entire useful life of the unit.
During the time when the drive units are in use, it is not necessary to change or monitor the amount
of the lubricant.
The actuators with plastic lubricant are labelled „Filled: solid grease“ on the power box at the side of
the hand-wheel.
Note: The Ciatim 221 lubricant is designed for the friction points of rubber bushings against metal surfaces, roller
brake, the hub of an outer cogged wheel of a planetary-gear differential (for locations of friction between the shaft
and other surfaces).

Actuators with oil charge
Check the level of oil at least yearly and refill, if required. Oil change should be made after 500 operating hours
of the actuator, but not later than after 2 years of operation. The level of oil should be as high as the filling hole.
For the actuator, Grade PP 80 motor-car gearbox oil or an equivalent oil with the same properties (viscosity class
80 W, according to SAE/J306a) should be used.
Maintenance
In case the actuator is operated in a dusty environment its surface should be regularly cleaned from dust in order to
prevent deterioration of its cooling.
It is necessary to smear lightly the trains of gears in the gearbox and the bearings on which these bearings are
supported as well as the lever system of the resistance transmitter every two years.
For greasing, apply grease CIATIM 201 or PM MOGUL LV 2-3. The bearings and gears of the current transmitter
should be lubricated with fine watchmaker’s oil. To increase corrosion resistance, all springs and leaf actuators in
the control section should be provided with a coating of grease. The adapter of the actuator, No. 52 036, should be
packed with 3 kg of PM MOGUL LV 2-3 grease.
11. FAILURES AND THEIR REMOVAL
1) Actuator in end position does not start, with motor buzzing
Make sure that no phase has been discontinued. If a slide valve has jammed and cannot be released even by
the handwheel the actuator should be dismantled and the jamming should be mechanically removed.
2) Self-stopping after starting of the actuator from the end position of the output shaft
In this case ensure that the slot of the change-over gear (Fig.2) stops in the end position of the actuator output shaft
(after operation of the torque-limit switch) before running onto the shifting device -21- (Fig.3). This can be achieved by
turning the output shaft round a suitable amount while the actuator is connected to the fitting, or by turning the change-
over gear round a suitable amount with respect to the output shaft. For this purpose, the change-over gearis provided
with two slots for a connecting spline. Moreover, the change-over gear can be reversed.
Caution!
The actuator, Type No. 52 036, has been engineered on the basis of a modified design variant of the actuator,
Type No. 52 035, which has been fitted with an adapter at its output. This adapter is a single-speed gearbox with spur
gears. The output shaft of the adapter also serves as the output shaft of the actuator, Type No. 52 036. The operation
of the control part is tied to the output shaft of the driving actuator, Type No. 52 035. To ensure that the direction
of rotation of the output shaft of the actuator, Type No. 52 036, corresponds to that of other Series MODACT MON
actuators, the following provisions have been made:
1) The markings of all controls and adjusting devices have been changed so as to comply with the direction of output
shaft rotation of the actuator, Type No. 52 036 (i.e., adapter).
2) The internal wiring of the control board of the actuator has been modified so that the wiring diagram of the actuator,
Type No.52 036, is identical to that of other Type Nos 52 030 - 52 035. Thus, the actuator, Type No. 52 036, can be
connected to external control circuits in the same way as are the actuators, Type Nos 52 030 - 52 035.
When adjusting the actuator, Type No. 52 036, it should be considered that the functions of microswitches are opposite
to those shown in the figures included in the Mounting Instructions. For example, in the actuator, Type No. 52 036,
the OPEN torque-limit switch (MO) is used instead of the CLOSE torque-limit switch (MZ) shown in the figure, etc.
When the hollow shaft in the control box rotates anticlockwise the fitting closes (with the output shaft of the actuator,
Type No. 52 036, rotating clockwise) provided that the spindle of the fitting is fitted with left-hand threads. The direction
of rotation of the handwheel is the same for all types of actuators.
The quantity of oil required is tabulated below:

capacitor.
The actuators MODACT MONJ are fitted with single-phase electric motors Siemens series 1LF7... with running and starting-up capacitors.
The manufacturer guarantees 60,000 and 100,000 start-ups for two-pole electric motors (ca 2800 r.p.m.) and four-pole electric motors
(ca 1400 r.p.m.), respectively. Then, it is necessary to replace the centrifugal disconnector of the starting-up capacitor – it is available at
ZPA Pečky, a.s.
In ZPA Pečky, a.s. electric motors of power up to 0.37 kW are fitted with a triac disconnector that extends the service life to 350,000 start-ups.
If the actuator with a single-phase electric motor is to be used for regulating purposes, it is necessary to take this fact into consideration in
setting-up the regulation process (frequency of regulating interventions).
The expected working regime of the actuators MONJ should be discussed with the marketing department of ZPA Pečky, a.s.
