Design and principle of operation

1 Design and principle of

operation

The Type 5757-7 consists of a digital con troller integrated into the housing of an elec tric actuator.

The combination is especially designed for heating applications as well as for fixed set point control of heating systems in small to medium-sized buildings. It is particularly suitable for mounting to SAMSON Type 3222, Type 3222 N, Type 2488 and Type 3267 Valves (DN 15 to 25) and to special versions of Type 3226 and Type 3260 Valves. The digital controller is connected to a flow sensor on the input side, which can be optionally upgraded by a return flow, outdoor or room sensor. In addition to the Pt 1000 input, the digital controller has a potentiometer input (1000 to 1100Ωor 1000 to 2000Ω) to measure the flow temperature. This input influences the heating characteristic in the case of outdoor temperature compensated control and the room temperature set point in the case of fixed set point control with room tempera ture influence. Heating characteristic and set point parame ters can be changed over the TROVIS-VIEW Operator Interface.

The output signal of the integrated digital controller is applied as a three-point step ping signal to the synchronous motor of the actuator. The signal is transferred over the connected gear to the actuator stem (3) and used as the positioning force. The motor is switched off by torque-depend ent switches when an end position is reached or in case the motor is overloaded.

The actuator is mounted onto the valve using a coupling nut (4). When the actuator stem extends, the valve is closed, opposing the force of the valve spring (7). When the actuator stem retracts,

the valve is opened as the plug stem (6) fol

lows the motion of the return spring. The valve can be moved to any position when the power supply is disconnected by the handwheel (2). Travel and direction of action can be read off the travel indicator (5) on the side of the actuator housing.

Electrical connection

3 Electrical connection

When installing electric lines, you are required to observe the regula tions governing electrical power plant installation according to DIN VDE 0100 as well as the regu lations of your local power supply company. Use a suitable power supply which guarantees that no dangerous volt ages reach the device in standard operation or in case of a fault in the system or any other system parts.

The controller with electric actuator requires a Pt 1000 temperature sensor (e.g. Type 5267-2) to be connected to measure the flow temperature. Depending on the control task, an outdoor sensor (e.g. Type 5227-2) or a room sensor (e.g. Type 5257-2) or a room panel (Type 5257-7 only) can be connected. Combining one of these sensors with a return flow sensor (e.g. Type 5267-2) is usually possible.

Additionally, the controller with electric ac tuator has a potentiometer input 1000 to 1100Ω(e.g. Type 5257-7) or 1000 to 2000Ω(e.g. Type 5257-2). This input is used to correct the room set point (±5 K) in case of fixed set point control with room temperature influence (see section 5.2). On using an outdoor sensor, it can change the adjusted heating characteristic (see sec tion 5.1). The non-floating pump output can alterna tively be used as an binary output for an ex ternal request for heat demand.

The connected sensors are monitored for line breakages. A fault in the line of a sensor is indicated by the red LED blinking slowly.

Caution!

Connect the actuator to the electrical network only after the power supply has first been switched off. Make sure the power cannot be switched on unintentionally!

The pump output L’ is non-floating (230 V~).

Perform the electrical connection de-

pending on the heating application according to one of the following wiring diagrams (Figs. 4 and 5). As soon as the actuator is connected to the power supply, the initialization procedure starts. The actuator stem extends (with operating direction selected for globe valves) and the red and yellow LEDs are illumi nated located under the cover on top of the actuator. As soon as the actuator stem has reached the final position, the red LED is turned off. The yellow LED remains illu minated and indicates that the controller with electric actuator is ready for opera tion.

5.1.3 Delayed outdoor temperature adaptation

The calculated outdoor temperature is used to determine the flow temperature set point. The heat response is delayed when the outdoor temperature either decreases, increases or in creases and decreases. If the outdoor temperature varies by, for example, 12 °C within a very short period of time, the calculated outdoor temperature is adapted to the actual outdoor temperature in small

The controller with electric actuator can issue a heat demand to a higher-level controller over the binary output BO in rated or reduced operation. In this case, a coupling relay (contactor relay with floating contact) must be used to adapt the electrical connection. This function is only possible when the binary output is not configured as a pump output.

5.8 Control principle

Functions

The controller with electric actuator functions with a PI algorithm (three-point stepping con trol). The valve reacts to pulses which the digital controller issues when a system deviation occurs. In particular, the length of the first pulse depends on the size of the system deviation and the selected gain rises). Pulse lengths and intervals change until the system deviation is eliminated. The interval between individual pulses is influenced considerably by the reset time

(the interval time increases as the Tn rises).

control

The valve transit time needs to move through its travel range from 0 to 100 %.

Note!

Do not change the default setting WE of P11 (Ty = 25 s) for this device.

7.2 SAMSON memory pen

The SAMSON memory pen serves as a data carrier and is able to load and store data in its non-volatile memory.

The memory pen can be loaded with data configured in TROVIS-VIEW and the settings transferred to one or several controllers with electric actuators. In the same way, the memory pen can be used to upload data from the actuator allowing you to simply copy the configuration data from one actuator to another actuator of the same type.

Note!

On inserting a memory pen that is empty or that contains data from another type of device into the serial interface port of the actuator, the data from the actuator are uploaded to the memory pen regardless of the status of the memory pen and any other data on the memory pen will be overwritten.
