Design and principle of operation

3 Design and principle of operation
The TROVIS 5757-3 Electric Actuator with
Process Controller is an electric actuator withan integrated digital controller. It can mounted on SAMSON Types 3213, 3222,
3222 N, 2488 and 3267 Valves (DN 15 to25) as well as special versions of Type 3260
and Type 3226 Valves.
DesignÎ See Fig. 3-1 and Fig. 3-2.
The actuator is mounted onto the valve using
a coupling nut (4). When the actuator stem
extends, the globe valve is closed, opposing

the force of the valve spring (7). When theactuator stem retracts, the valve is opened as
the plug stem (6) follows the motion of the
return spring.
When connected to a three-way mixing
valve, the extending actuator stem causes thevalve (A → AB) to open.
The output signal of the controller functions
as a three-step signal on the motor of theactuator and is transferred over theconnected gear to the actuator stem (3) andused as the stroke. The motor is switched off
by torque-dependent switches when an end
position is reached or in case the motor isoverloaded.

set point controller with this input. Alternatively, the electric actuator can be used fordomestic hot water in instantaneous heating
system. In this case, either a water flow sensor or a flow switch must be used for fast detection. The flow switch recognizes when the
hot water is being tapped. The water flow
sensor can additionally record the quantityof hot water being tapped. An optimization
function adapts the control to the changing
network conditions.
In addition to the temperature sensor input,
the actuator has a 0/4 to 20 mA current input. This can be used either instead of thetemperature sensor (measured value) or toconnect an external set point.
The binary input can be used to change between the set points W1 and W2.

Start-up and configuration

7 Start-up and configuration
7.1 Initializing the actuator
The initialization process starts automaticallyafter the actuator has been connected to the
supply voltage. The actuator stem extends(when the direction of action increasing/increasing has been set) and the red and yellow LEDs underneath the cover on top of theactuator are illuminated. As soon as the actuator stem has reached the final position,
the red LED is turned off. The yellow LED remains illuminated and indicates that the actuator is ready for use.
Blinking pattern of the red LED:
Zero calibration in progress

7.2 Configuring the actuator
The actuator is configured with the TROVISVIEW software. In this case, the serialinterface on the actuator is used to connect
the actuator to the computer (see the 'Design
and principle of operation' section).
Î Refer to u EB 6661 and u KH 5757 formore details on configuration and operation using TROVIS-VIEW.
Note
The Configuration Manual u KH 5757 canbe found in the Help menu of the TROVISVIEW software. The manual contains adetailed description of each function andparameter.

8 Operation
The valve with electric actuator is ready for use when mounting and start-up have been completed.

8.1 Closed-loop control
The electric actuator with process controller normally operates in closed-loop operation. In
this case, the control behavior and movement of the actuator stem depend on the parametersettings (see Configuration Manual u KH 5757).

Operation

8.3 Manual mode
Manually changing the stem position
The manual adjuster can be used to move the actuator stem to the required position when theactuator is in the de-energized state. A manual adjustment of the stem position only makes
sense when the power supply is switched off as the stem position is determined by theactuator in closed-loop operation, meaning any manual adjustment would be automaticallycorrected by the actuator.
The stem position is changed at the manual adjuster (see Fig. 8-1):
Î Switch off the supply voltage.
Î Turn clockwise
The actuator stem extends (approx. four turns for 1 mm travel).
Î Turn counterclockwise
The actuator stem retracts (approx. four turns for 1 mm travel).
Travel indicator
Travel and direction of action can be read
off the travel indicator on the side of the actuator housing (see Fig. 8-2).

Operation

8.4 Operation using memorypenu EB 6661.
The memory pen can be loaded with data
configured in TROVIS-VIEW and the configuration data transferred to one or several
devices of the same type and version.
Additionally, the data from the device canbe written to the memory pen. This allows
the configuration data to be simply copiedfrom one device and loaded onto other devices of the same type and version.

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

Data transmission between the actuatorand memory pen
The memory pen is connected to the actuator
as shown in Fig. 8-3. Refer to the TROVISVIEW Operating Instructions u EB 6661 on
how to transfer data.
The yellow LED on the actuator indicates thatthe data logging is being prepared. Datatransmission is completed when the yellow
LED is illuminated continuously.

8.4.1

Copying function

The memory pen can be used to copy setting
data to other TROVIS 5757-3 Actuators after
