Safety instructions

General safety instructions

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.

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 op-

tionally 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 1100 Ωor 1000 to 2000 Ω

) to measure

the flow temperature. This input influences

the heating characteristic in the case of out-

door 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.

2 Connection to the valve

The actuator has a force-locking connection

to the valve in de-energized state.

4Turn the handwheel (2) counterclockwise

to retract the actuator stem as far as it

will go.

4Place the actuator on the valve connec-

tion and screw coupling nut (4) tight

(tightening torque 20 Nm).

2.1 Mounting position

Any mounting position may be used, how-

ever, may not be installed in a suspended

position.

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. Com-

bining 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

1100 Ω(e.g. Type 5257-7) or 1000 to

2000 Ω(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~).

4Perform the electrical connection de-

pending on the heating application ac-

cording to one of the following wiring di-

agrams (Figs. 4 and 5).

As soon as the actuator is connected to

the power supply, the initialization pro-

cedure starts.

The actuator stem extends (with operat-

ing 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.
