Assembly, start-up and operation of this device may only be performed by trained and experienced personnel familiar with the product. According to these mounting and operating instructions, trained personnel refers to individuals who are able to judge the work they are assigned to and recognize possible hazards due to their specialized training, their knowledge and experience as well as their knowledge of the applicable standards.
Any hazards which could be caused in the connected valve by the process medium, operating pressure or moving parts are to be prevented by means of the appropriate measures.
Proper transportation and storage are assumed. The actuators has been designed for use in electrical power installations.
For wiring and maintenance, you are required to observe the relevant safety regulations. The actuator must be protected against unintentional reconnection of the power supply.
Note:
Actuators with a CE marking fulfill the requirements of the Directives 94/9/EC and 89/336/EEC. The Declaration of Conformity is available on request.

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

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 Outdoor temperature compensated control
In the outdoor temperature compensated control, the flow temperature (tVL) is automatically adjusted in relationship to the outdoor temperature (t troller defines the set point for flow temperature as a function of the outdoor temperature (Fig. 8). Basically, the following correlation exists: If the outdoor temperature drops, the flow temper ature rises. By varying the
