Design and principle of operation

3 Design and principle of oper-ation

The actuator contains a reversible synchro-nous motor and a maintenance-free gear. The motor is switched off by torque-depen-dent limit contacts or in case of overload.The force of the motor is transmitted to the actuator stem (3) via gear and crank disk. When the actuator stem extends, the actua-tor piston (3) pushes against the valve's plug stem. When the actuator stem retracts, the return spring in the valve causes the plug stem to follow the movement (force-locking connection).Actuator and valve are connected by the coupling nut (4).

Type 5824 without fail-safe actionThis actuator without fail-safe action has a handwheel (2) used to manually position the valve. Travel and direction of action can be read off the travel indication scale (9).Type 5825 with fail-safe actionThe actuator contains a spring mechanism (8) and an electromagnet. The actuator is moved by the force of the spring to the fail-safe position when the electromagnet (termi-nals L and N) is de-energized. The direction of action depends on the actuator version and cannot be reversed.The Type 5825 Actuator is available with fail-safe action "actuator stem extends" or "actuator stem retracts".

Î The fail-safe action must not be used to control the valve position.

The Type 5825 Actuator does not have a handwheel (2) on the housing cover. Manual override is possible, after removing the front cover, using a 4 mm Allen key. The actuator returns to its original position as soon as the Allen key is released.

Version with faster motorThe Types 5824-13/-23/-33 and Types 5825-13/-23 have a more powerful motor in a housing at the back of the actua-tor.

Testing according to DIN EN 14597The Types 5825 Electric Actuator with fail-safe action "actuator stem extends" is tested by the German technical surveillance associ-ation (TÜV) according to DIN EN 14597 in combination with various SAMSON valves. The register number is available on request.

3.1 Cover screwsThe actuator housing cover is fastened using TORX PLUS® screws, size 10IP.

Î To loosen and tighten the screws, the fol-lowing screwdrivers can be used:

− TORX® T10 − TORX PLUS® 10IP − Flat-blade screwdriver with 0.8 mm

blade thickness and 4.0 mm blade width

3.2 Additional equipment − The resistance transmitter is linked to the

gear and produces a resistance signal between approx. 0 and 1000 Ω (use-able range 0 to 800 Ω ) proportional to the valve travel. The resistance transmit-ter is not suitable for retrofitting.

− On request, the actuator can be fitted with two limit contacts. Optionally, the actuators can be equipped with two limit contacts, which are actuated by continu-ously adjustable cam disks.The power supply as well as the inputs and outputs are not galvanically isolated. The two additional limit contacts are not suitable for retrofitting.

Fail-safe action "actuator stem retracts" Î Place the actuator on the valve connec-tion and tighten coupling nut (tightening torque 20 Nm).


Î For fail-safe action “actuator stem re-tracts” and “actuator stem extends”, mount actuator as described in sec-tion 5.1.2.

NOTICE!

5.2 Installing the control valve into the pipeline

Î Install the valve into the pipeline accord-ing to the mounting and operating in-structions of the valve.

Î The control valve can be installed in the pipeline in any desired position. Howev-er, a suspended mounting position of the actuator is not permissible (see Fig. 5).

The IP 54 rating can only be achieved up to device index .03 when the actuator is installed in the upright position. See the last two figures of the configuration ID on the nameplate (see p. 11) for the index.

5.3 Electrical connections

Risk of electric shock. − Upon installation of the electric cables, you are required to observe the regulations concerning low-voltage installations ac-cording to DIN VDE 0100 as well as the regulations of your local power supplier. − Use a suitable power supply which guar-antees that no dangerous voltages reach the device in normal operation or in the event of a fault in the system or any other system parts. − Connect the actuator to the electrical net-work only after the power supply is first switched off. Make sure the power cannot be switched on unintentionally.

− If voltage is applied to eL, the actuator motor retracts the actuator stem.

− If voltage is applied to aL, the actuator motor extends the actuator stem.

Risk of damage to the actuator due to incor-rect connection of the voltage.Do not apply a voltage to eL and aL at the same time.

5.3.1 Connecting the power supply

Î Connect the wires through the cable en-tries (1.2, Fig. 1) according to Fig. 6.

Î The interference suppression capacitors in the output circuit of the connected con-troller must not exceed a value of 2.5 nF to ensure the proper functioning of the actuator. A special actuator version is available on request for connection to controllers with larger interference sup-pression capacitors.

Î Connect actuators operated in parallel over separate contacts to prevent the ac-tuators hunting in the end positions due to a shared OPEN or CLOSED contact.

Î Connect power supply to terminals L and N in Type 5825.

6.1 Limit contacts

Risk of electric shock from exposed live parts.Do not touch live parts on adjusting the limit contacts.

The limit contacts (6, Fig. 1) can optionally be used as make or break contacts.Terminal assignment (Fig. 6): − Terminals 41, 44, 42:à Bottom cam disk, adjuster 7.1

− Terminals 51, 54, 52:à Top cam disk, adjuster 7.2

1. Unscrew front cover.2. Move the actuator stem to the position at

which switching point is to be activated.3. Use a 4 mm Allen key to turn the adjust-

ers (7.1 or 7.2 in Fig. 1) up to the point where the contact is triggered.

The angle of rotation of the cam disks is lim-ited. Therefore, use preferably the top adjust-er (7.1) for the upper travel range and the bottom adjuster (7.2) for the lower travel range.

6.2 Resistance transmittersAs the valve passes through its travel range, the resistance value changes from 0 Ω to ap-prox. 80 % of its nominal value. Turn a screwdriver placed on the slotted shaft to calibrate the resistance transmitter.Calibrating the actuator with an extended actuator stem at 0 Ω1. Connect ohmmeter to terminals 61 and

62 (see Fig. 6).2. Extend the actuator stem to its end posi-

tion.3. Turn the resistance transmitter counter-

clockwise as far as it will go. The ohm-meter indicates the initial value of ap-prox. 0 Ω.

Calibrating the actuator with a retracted actuator stem at 0 Ω1. Connect ohmmeter to terminals 61 and

63 (see Fig. 6).2. Retract the actuator stem to its end posi-

tion.3. Turn the resistance transmitter clockwise

as far as it will go. The ohmmeter indi-cates the initial value of approx. 0 Ω.

4. Only for actuators with 6 or 12 mm travel: Slowly turn the resistance trans-mitter counterclockwise up to the point where the resistance changes from 0 Ω.

Type 5824 ActuatorUse the handwheel to adjust the travel (ap-prox. 4 turns for 1 mm): − Turn clockwise:

The actuator stem extends. − Turn counterclockwise:

The actuator stem retracts.

Type 5825 Actuator

Risk of electric shock from exposed live parts.Do not touch live parts on operating the manual override.

1. Unscrew front cover and place a 4 mm Allen key on the red actuating shaft.

Risk of damage to the actuator by turning it too far.Only retract the actuator stem as far as the final travel value.

2. Turn the Allen key: Î Turn it counterclockwise only for a ver-sion with fail-safe action "actuator stem extends".

Î Turn it clockwise only for a version with fail-safe action "actuator stem retracts".

3. Turn the Allen key only as far as the final travel value, which is at the point where the torque-dependent limit switch is acti-vated.Once the magnet has been released, the spring mechanism pushes the actuator stem back to the fail-safe position.

4. Remove Allen key and carefully refasten the front cover.
