MD200Y actuator . Use The compact MD200Y actuator with a thrust of 850N makes fine adjustments to the stroke of valves. The MD200Y for a 24V AC mains supply is controlled by a continuous Y 0..10V DC or 2..10V DC signal. Model MD200Y 24V AC actuator with continuous 0/2..10V DC control

. MD200Y actuator Manual/automatic mode Manual or automatic operation is selected directly on the actuator using the manual switch on the actuator cover. Automatic mode: Move switch to Manual mode: Move switch to Manual mode can be easily recognized in poorly lit rooms as the slide indicator protrudes. The actuator can then be set to the required valve position using the handwheel. The actuator returns to automatic mode when manual mode is switched off. Position indicator on the actuator Two position marks on the actuator console indicate the upper and lower valve end positions. The current stroke position of the valve is indicated on the bridge between the two position marks. Other actuator functions Valve block protection feature The valve block protection feature is switched off on delivery. The valve block protection feature can be activated during commissioning if system conditions permit it. The valve block protection feature prevents the cone from locking when the valve is idle for a longer period of time, e.g. in heating systems during summer. When valve block protection feature is activated, the valve cone is raised for a few seconds if there has been no stroke for 24 hours. Automatic fault message If the valve stroke is blocked by foreign objects in the pipeline, the actuator indicates this fault sending a feedback signal of approx. 13V DC at terminal A. The LED under the actuator cover also flashes. Using an automatic remedy algorithm, the actuator then tries repeatedly to unblock the valve by raising the valve cone for short periods of time. Additional audible or visual fault messages can be achieved using the E/MDY (accessories) switch module. Offsetting outside interference To prevent the actuator from vacillating when outside interferences are overcoupled on control line Y, the input hysteresis band is automatically increased. If the fault does not occur again, hysteresis is re-adjusted to minimum values. This function prevents outside interference to a large extent and unnecessary temperature fluctuations and wear on the actuator and valve. Zero crossing The economical 3-wire connection combines the floating voltage of control line Y (DC) and power line (AC) in a single line. To minimize errors in the Y control signal caused by line drop when long lines are used, the actuator electronics processes the Y control signal only when the alternating current is at zero crossing.

. Installing the MD200Y actuator

Only qualified professionals may install the actuator!

The MD200Y actuator can be mounted on valves RK15..50/RK65K(-BF), RB15..50(-BK), RB15..50SO17(-BK), RF15..50/RF65K(-BF), RFH15..25, RGD15..40 and RWG15..40. • The actuator is delivered in a middle stroke position.

It is mounted on the valve while the stroke is in this position. The following figures illustrate the mounting of the actuator on an RF32 three-way valve.

If the valve is mounted in the system, you must make sure that no differential pressure can occur within the valve before beginning assembly. If necessary, close the slide valve and switch off pumps.

The actuator can be installed once the pipeline has cooled down.

Tighten the drive ring using an Allen wrench (hexagon socket 2.5 mm).

. Installing the valve

Only qualified professionals may install the valve!

The generally valid installation guidelines for pipeline work as well as the following must be observed: • The pipeline system and valve interior must be free of foreign objects.

When dirty media are used, strainers must be installed. • The valve-pipeline connection must not become warped. • The valve must be inserted into a straight pipeline to prevent eddies from forming inside the valve.

The recommended value between the valve flange and manifold or similar device is 10 x nominal diameter. • The installation location must ensure that the ambient temperature at the actuator is 0..50°C. • The max. permissible pressure difference ∆p and the specified flow direction must be observed. See valve

models and valve cross-sections with flow directions. • Three-way valves are preferably used for mixing. Distribution can generate noise. • Blank cover BK allows three-way valves RB15..50/RB15..50SO17 to be used as two-way valves to control

volume. Blank flange BF allows three-way valves RK15..50/RK65K and RF15..50/RF65K to be used as two-way valves to control volume.

• The flange valve gates have protective caps to keep out impurities. The caps must be removed before the valve

is installed. • The actuator can be installed vertically above the fixture to horizontally. • A space of around 100mm must be left above the top of the cover for removing the actuator cover.

When installing a valve without an actuator, around 350mm space must be left for the actuator. • A protective box is provided for the actuator. It protects the actuator during the construction phase and during

pipeline work until it is commissioned.

. Commissioning

Caution! Mains voltage can be 230V when using the E/MDY switch model (accessory)! Only qualified professionals, e.g. a commissioning engineer, may commission the system!

• General note

Only specialists may operate the actuator in automatic mode while the cover is removed!

For safety reasons, the actuator switches to manual mode when the cover is removed. The included solenoid switch -A- can be used to switch the actuator to automatic mode to allow the commissioning engineer to check the function of the actuator. To do so, plug the solenoid switch -A- into the PCB -B- after removing the cover.

1. Ensuring that the actuator is installed correctly and checking the electrical connection 2. Adjusting valve function.

The valve function is adjusted using 4 switches under the actuator cover.

·1· Switch Y 2-10V/0-10V Switches to control voltage Y from controller 0..10V DC or 2..10V DC.

·2· Switch Y/Y

Position feedback 0..10V DC for 0..100% valve stroke. Setting is only necessary if a position indicator is connected to terminal A.

Feedback if valve is blocked and if manual switch is activated: approx. 13V DC. The LED under the actuator cover also flashes.

·4· Switch M Setting position for partial initialization. After a power failure or manual adjustment, the actuator is partially initialized for safety reasons. The direction is set to valve open or valve closed in compliance with system conditions. The actuator returns to automatic mode following partial initialization.

3. Switching on the mains supply

LED ·D· flashes. 4. Initializing and adjusting to the valve stroke

The initialization process is switched on by pressing the INIT -C- key. During initialization the valve is opened and closed completely once, and the handwheel makes short stops during the process. The actuator first moves to the partial initialization position (set using switch .4., section 2.).

LED -D- flashes during initialization. It stops flashing and remains illuminated when initialization is complete. The INIT key and the LED are located underneath the actuator cover (see figure).

During initialization, valve block protection feature can be switched on, and the overload detection feature can be checked (see sections 5 and 6).

. Commissioning 5. Valve block protection feature

The valve block protection feature prevents the cone from locking when the valve is idle for a longer period of time, e.g. in heating systems during summer. When valve block protection feature is activated, the valve cone is raised for a few seconds if there has been no stroke for 24 hours.

The valve block protection feature is switched off on delivery. If system conditions permit it, the valve block protection feature can be activated. The valve block protection feature can be switched on during the initialization phase.

Switch on the valve block protection feature by pressing the key -E-.

The LED -D- continues to flash during the initialization phase to indicate that the valve block protection feature is switched on. If the actuator is already initialized, the LED -D- flashes for 3 s to indicate that it the valve block protection feature has been switched on.

Switch off the valve block protection feature by pressing the key -E- again.

The LED -D- switches off for 3 s to indicate that the valve block protection feature has been switched off.

The key -E- and the LED -D- are located underneath the actuator cover (see figure, page 28).

Following a power failure, the actuator turns for 1 s against the partial initialization to indicate that the valve blocking feature is switched on. See section 2. Adjusting valve function, switch .4., You can determine if the function is activated even if the cover is closed.

6. Overload detection

Long periods of pressure differences that are higher than permissible values in the valve lead to overload, which can affect the service life of the actuator. Pressure differences that are above permissible levels are indicated in the window of the gear cover under the cover during commissioning. If the gear wheel moves outside of the middle window position (except when the valve is in one of the two end positions), the pressure difference in the valve is too high. Maximum pressure differences ∆p (bar) are specified in the valve descriptions of the individual valve models for all nominal diameters.

7. Accessories

If the actuator has additional built-in parts (see accessories), they must also be checked to make sure they are functioning properly and must be set if necessary.

When doing so, the descriptions and connection instructions of the accessories must be observed!

8. Checking the function

After making settings on the actuator and any accessories, the actuator cover must be placed back onto the actuator and attached with screws. All functions of the actuator must then be checked within the system.
