Note: These Mounting and Operating Instructions EB 5757-7 EN are valid for firmware ver-

sions 2.00 to 2.09.

The latest edition of these instructions, detailing the firmware version and modifications com-

pared to the previous version, is available on the Internet at http://www.samson.de.

1 General safety instructions

For your own safety, follow these instructions concerning the mounting, start up and opera-

tion of the actuator:

4Mounting, 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.

4Any hazards that could be caused by the process medium, operating pressure or by

moving parts are to be prevented by means of the appropriate measures.

4The actuators has been designed for use in low voltage installations.

For wiring and maintenance, you are required to observe the relevant safety regulations.

Take necessary measures to ensure that the power supply cannot be reconnected

inadvertently.

4Before wiring the controller with electric actuator, disconnect it from the power supply.

To avoid damage to any equipment, the following also applies:

4Proper shipping and appropriate storage are assumed.

Note: Actuators with a CE marking fulfill the requirements of the Directives 2004/108/EC

and 2006/95/EC.

The Declaration of Conformity is available on request.

General safety instructions

2 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 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 by

the handwheel (2) when the power supply

is disconnected. Travel and direction of ac-

tion can be read off the travel indicator (5)

on the side of the actuator housing.

Slide switch

The slide switch allows you to switch be-

tween two different configurations #1 and

#2. In position #1, the slide switch points to-

wards the outside of the housing and in po-

sition #2 towards the middle of the housing.

In both levels #1 and #2, the functions de-

scribed in section 6 can be activated and

the associated parameter settings made.

The default settings is the same for both lev-

els #1 and #2, except for function block

F13.

Changes to functions and parameters can

be made over the TROVIS-VIEW software.

Refer to section 7.

The position of the slide switch determines

which function and parameter settings (level

#1 or #2) is used for closed loop operation.
