APPLICATION The MODACT MOK actuators have been designed for remote control of flaps, ball valves and other actuating devices which require up to 90°rotary action and tight closure in end positons. A typical example of application is control of ball valves, flaps and similar devices in the remote and automatic control mode. The actuators are attached directly to the control device.
DESCRIPTION AND FUNCTION The actuators consist of a power section and a control section. The power section is formed by an epicyclic gear unit, a worm gear drive for manual control and an electric motor. The control section consists of a position-limit switching and signalling unit with a position transmitter and a torque -switching unit. For microclimate conditioning of the control compartment, a built-in anti-condensation heater is used. For connection of the actuator to external circuits, a terminal board is fitted. The movements of the actuator output shaft are transmitted to the position-limit and signalling switches as well as to the position transmitter. Worm axial displacement, which depends on the load torque of the actuator, is transferred to the torque-limit switches. The actuator can be equipped with a position controller, if required by the customer. In this case, the actuators are trade-named MODACT MOK Control .

OPERATING CONDITIONS The actuators MODACT MOK (MODACT MOK Control) should withstand the effect of operating conditions and external influences, classes AA7, AB7, AC1, AD5, AE5, AF2, AG2, AH2, AK2, AL2, AM2, AN2, AP3, BA4 and BC3, according to ČSN Standard 33 2000-3 (mod. IEC 364-3:1993). 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.
Classes of external influences Basic characteristics - as extracted from ČSN Standard 33 2000-3 (mod. IEC 364-3:1993). 1) AA7 -
Simultaneous effect of ambient temperature of - 25 °C to + 55 °C with relative humidity from 10 % upwards 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/m2 and ≤ 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 Note: MODACT MOK actuators (but not MODACT MOK Control) type Nos. 52 325 to 52 329 may be also ordered in EE x nC IIB T3 finish. These actuators cannot be equipped with local control change-over switch. They can operate in zone 2 – protection type “n” according to ČSN EN 50021 Standard.
TECHNICAL REQUIREMENTS Supply voltages of the actuators
Servomotory t.č. 52 325, 52 326, 52 327 1x230 V Supply voltages of the actuators are shown in Tab. 1. - 15 %
+10
±2 %
1x230 V +10%, -15%; 50Hz ±2 % 3x400 V +10%, -15%; 50Hz ±2 % If another supply voltage is to be used for the actuator this should be consulted beforehand with the manufacturer.
Operating position The actuators can be used in any operating position.
Duty The actuators can operate at the rated load torque corresponding to 50% of the maximum tripping torque, in duty S 2 for 10 minutes or S 4 with a load factor of 25 % and at a switching rate of 1,200 switching cycles per hour.
Self-locking Self-locking facility of the actuators is provided by a mechanical or electromagnetic brake of the electric motor. The actuators are self-locking.
Manual control The actuators are controlled by a handwheel providing for their direct control without clutch.
Switches Each actuator is fitted with 6 quick-action one-chamber microswitches having the following parameters: 6A 250 V AC resistance load 2A 250 V AC inductive load, cos phi = 0.6 0.2 A 250 V DC resistance load L = 3 ms 0.1 A 220 V DC inductive load, — R
4
Anti-condensation heater To prevent water steam condensation, the actuators are fitted with an anti-condensation heater; the latter can be connected to the AC or DC voltage of 230 V.
Position potentiometer, local position indicator A dual Potentiometer of 2 x 100 Ω + max. 12 Ω is used. In the „closed“ position, the resistance between terminals should be at least 93 Ω, whereas in the „open“ position it should not exceed 5 Ω. The transmitter can be used in circuits at a voltage up to 50 V DC with currents whose value should not exceed 100 mA. The CPT 1/A current transmitter is a current device in a two-wire arrangement with the following parameters: Transmitter output signal 4 - 20 mA or 20 - 4 mA (±0.1 mA) Transmitter working angle 0° - 60° to 0° - 90° Maximum load resistance 500 Ω Supply voltage 24 V DC Maximum supply voltage 30 V DC The actuator can have a built-in power supply except for the MODACT MOK 63 Control design variant. The wiring instructions of the current transmitter are given on the wiring diagrams. The actuators are fitted with a local position indicator that has been adapted for the full working stroke of the actuator, i.e., 90°.
Terminal board of the actuator The terminal board of the actuator is fitted with terminals allowing one copper or aluminium conductor with a maximum cross-section of 2.5 mm2 or two conductors with the same cross-sectional area up to 1 mm2 to be connected.
POSITION REGULATOR A built-in position regulator allows automatic positioning of the actuator output shaft to be performed, depending on the analog input signal. At the regulator input, the input control signal is compared with the feedback signal of the position transmitter. The resulting control deviation, if any, is used for actuator run control, the actuator output shaft being brought into the position corresponding to the input control signal value. This regulator uses the high performance of the RISC processors MICROCHIP for performing all its functions, while at the same time enabling continuous system self-diagnosis to be effected and error messages to be displayed whenever a failure occurs. Due to this facility, the user need not make complicated adjustment as in the case of a current analog regulator. For this purpose, it is sufficient to start the initializing program to make the regulator perform all necessary functions.
REGULATOR SOFTWARE 1) The regulator can be programmed to perform the required functions in the following two ways: - By a PC after the RS 232 interface. - By means of the functional keys and LEDs on the regulator. The following parameters can be programmed: - Control signal - Regulator response to the TEST signal and the error state (depending on the programmed requirements) - Mirroring (ascending or descending characteristic of the control signal) - Regulator insensitivity - Way of Regulations (narrow to a moment, narrow to a position, wide to a moment, wide to a position) 2) All operating states of the regulator can be monitored by a PC after the RS 232 interface. In this case, the regulator issues error messages by means of LEDs or PC. - Presence of the TEST signal - Control signal is missing - Limit switches (faulty connection) - Failure of position sensor - Failure of thermal protection

Notes: ad. 1) The feedback signal can be brought out provided that its galvanic separation from the input signal has been ensured. ad. 2) The TEST signal can be activated by an external make contact. This signal need not be connected. ad. 3) From the terminals 25 and 26 (at MODACT MOK 125, 250, 500 and 1000), 77 and 80 resp. (at MODACT MOK 63), a failure signal can be brought out. This signal is galvanically separated from the regulator circuits. The maximum voltage which can be applied to theseterminals, is 24 V. In the design variant with the CPT1/A current transmitter, the user should provide for connection of the two-wire circuit of the current transmitter to the electric earth of the associated regulator, computer, etc. The connection should be made only at a single point in any section of the circuit outside the electric actuator. The voltage between electronics and the current transmitter case should not exceed 50 VDC. In the ZP2.RE regulator, all circuits of the CPT 1/A current transmitter are connected to the input signal circuits and the circuits connected to the regulator TEST terminal. The electric earth connection of these circuits should be made only at a single point of one of the three circuits, while other circuits should not be connected to the earth.
