2. EC Manufacturer’s Declaration

The manufacturer, Georg Fischer Piping Systems Ltd., CH 8201 Schaffhau­sen, declares that the electrical actuator EA 21 / 31 / 42 is not a ready-to-

use machine in the sense of the EC Machine Directive and therefore cannot
meet all the requirements of this directive.

Operation of these actuators is prohibited until conformity of the entire
system into which the valve and the actuator have been installed is estab­lished according to the EC Directives listed below.

Applied EC Directives:

06/95 EC EC Low Voltage Directive
89/336 EEC EC Directive on Electromagnetic
Compatibility

Modications to the actuator which have an effect on the technical data
given in this instruction manual and its intended use, i.e. signicantly alter
the actuator, render this manufacturer’s declaration null and void.

3. Intended use

When mounted on a valve and connected to a system control and provided
that the actuator data corresponds to the electrical control and the valve,

the purpose of this actuator is:

• to actuate valves with up to 180° pivoting (ball valves and buttery
valves),

• to indicate the previously calibrated end positions of the valve via elec­trical signal to the system control (accessory), and

• in case of a power supply interruption the actuator valve remains in its
current position (without accessory). Please use emergency manual
override or install fail-safe return.

The actuator is not intended for uses other than those listed above. If the
instructions contained in this manual are not observed, the manufacturer is
excluded from all liability for the above mentioned products.

4. Safety Information

4.1 Due care required by the operator

The actuator described herein was designed and manufactured with consi­deration to the respective harmonized European standards. It corresponds
to the latest technology and the technical specications contained under
section 6.3.

Safety on the job can, however, only be realized if the operator warrants that

• the actuator is only used as indicated under section 3,

• he is familiar with this instruction manual and the manual of the corres­ponding valve and adheres to the instructions contained therein and

• he has taken the necessary measures against electrostatic inuence.

4.2 Special hazards

Under normal conditions, the actuator may only be operated with the
cover closed.
If work is performed on the actuator with the cover removed, the supply
and control voltage must rst be disconnected. Adjustments, which need
to be done in the energized state, should be carried out with special insu­lated tools.

39

In addition, the operating instructions of the manual valve
must be observed. They are an integral component of this
manual.

4.3 Transport and Storage

The actuators must be handled, transported
and stored with care. Please note the following
points:

• The actuators should be transported and/or stored in
their original unopened packaging.

• The actuators must be protected from harmful physical
inuences such as dust, heat (humidity).

• It is important that the connections are neither dama­ged by mechanical nor by thermal inuences.

• Prior to installation, the actuators should be inspected
for transport damages. Damaged actuators must not be
installed.

5. Actuator Design

The standard version of the EA 21/31/42 electrical actuator
consists of the following elements: gear unit, direct current
motor, electrical board and components for end position
limiting.

1. Limit switches S1 and S2

2. Direct current motor

3. Optical position indicator

4. Plug X1 for accessories

5. Terminal strip for external
connections max. 1.5 mm

6. Wide range power supply,
without protection against
accidental contact

7. Shaft for emergency manual
override

Installation note

If the actuator is directly connected to the power supply, it
is necessary to install a disconnector between the actuator
and the power supply (do not disconnect the earth cable).
Cross-section of the external cables max. 1,5 mm2.
To avoid water owing into the actuator, make sure the cable
entry point is not upturned.

The EA 21/31/42 has a temperature control (ready-to­operate monitoring).

Due to the loading of the power supply capacitor
when rst time switching on the actuator current
peaks can occur for a few micro seconds. The­refore we recommend to connect the actuator in
accordance with accompanying wiring diagram.

5.2 Error message

If an error occurs, the red LED (8) on the base board will
light up.
If the monitoring print is installed, the LED (7) on the BCD
switch (10) which selected value has been exceeded will also
light up red.

Releai scontact
max. 2 4V

With all occurring error messages the ready-to-operate
signal will be off (terminals 5,6 no passage).

Eliminating the error message

Check the error cause, if necessar y carry out the appropri­ate maintenance.

To eliminate the message, activate the reset switch (9) on
the base board while the supply voltage is still connected
or briey disconnect the actuator from the mains voltage.

mains:

• Does the main voltage correspond to the spe­cications given on the type plate

• Has the actuator been connected correctly
(see Section 5.1)

• Fuse ≥ 6 A

Adjustments

If a complete valve is supplied by Georg Fischer, no further
adjustments are required. After installation by the customer
or after repair, the end positions should be checked and
adjusted if necessary.

the DIP switch (8) on the monitoring print it can be preset, if
the actuator should keep moving in this case, or if it should
move to its security position and remain there. (refer to
section error message).

7.6 Position Signalization

Description Technical data Code

Position
signalization

The position signalization enables determining the exact
mechanical position of a valve. Output signal is a current of
4 – 20 mA. (4mA-CLOSED, 20mA-OPEN).

The position signalization can be combined with the positi­oner or the monitoring print.

The position signalization board is mounted on the limit
switches S1, S2 and is connected electrically to the positio­ner or the monitoring print via a system cable.

Mounting the position signalization

1. Disconnect the actuator from the supply voltage.

2. Remove the screws of the limit switches S1 and S2.

3. Remove the position indicator (1).

4. Place the position signalization board in the position
shown on S1 and S2 and fasten with the longer screws.

5. Insert the toric magnet (3) so that the notches are on the
top.

Again place the position indicator (1) on the axis in one of

the end positions.

6. Connect the position signalization board to the control­ler or monitoring print via the system cable (2).

Reconnect to the power supply.

The board has been connected correctly when the LED

(4) lights up green.

If the position signalization is used

together with additional limit switches,

the position signalization as to be in
stalled above the limit switches.

Setting the position signalization

For the position sensor (4) to recognize the OPEN and
CLOSED positions, a single learning run with 360° must be
done. After the learning run, the OPEN and CLOSED positi­ons are set.
Further learning runs can be done between the end positi­ons (depending on the switching cams S1 and S2).
The way how the jumper is placed on the position signaliza­tion determines if the learning run happens with 360° or if it
happens between the end positions.

Jumper connects both PINs: learning run 360°
Jumper doesn’t connect the PINs: learning run bet
ween the end positions

When position signalization is mounted ex

factory, a learning run with 360° has been
already done. In this case the jumper is
placed on only one PIN. When the position
signalization is mounted by the customer a
360° learning run has to be done. Therefore
the two PINs need to be connected by the
jumper.

Subsequent modications on the switching

cams requires a new learning run.

6

Learning run 360° (Position signalization

kit subsequently installed)

It is necessary to separate the actuator from

the valve, to avoid damage to the valve. Be­fore doing the learning run set the jumper so
it connects the two PINs. Complete learning
run. Then reset the jumper to its original
position and remount the actuator.

Doing a learning run

Press the button (5) on the board for ca. 2s. (The LED (6) will
go out briey. As soon as the LED lights up again, release
the button). The actuator will do a learning run with several
longer pauses.

61

During this run, the LED (6) will blink. While the LED (6) is blinking, the
actuator is in the learning mode. The learning run is only nished when the
LED lights continuously.

7

If the position signalization is combined with the monitoring print, the
output signal 4 – 20 mA can be processed on the terminals 18, 19 (7) on the
board of the monitoring print. (4 mA > CLOSED / 20 mA > OPEN).

If the position signalization is connected to the positioner, the latter will
process the signal.

7.7 Positioner

Description Technical data Code

Positioner type PE 25 199 190 100

The positioner type PE 25 controls a user-dened valve position proportio­nal to a given set value. This can be 0-10V or 4-20mA.

Power supply needs to be galvanically isolated.

62

The return of the valve position (actual value) is realized with the position
signalization.

The control parameters are pre-set ex factor y and do not need to be chan­ged.

Signal conguration

The four DIP switches on the controller print serve for the
conguration of the signals.

Mounting the positioner

1. Disconnect the actuator from the supply
voltage.

2. Take the controller board out of the packaging and
check for damages.

Do not touch the board itself. Electrostatic

discharge can damage the components.

3. Place the board vertically on the back side of the base
board on plug X1. (see page 47)

Make sure that the board is inserted exac

tly in the guides at the side.

Setting the position signalization see Section 9.6

Connecting the positioner

For the positioner to receive the set value signal, connect
the terminals of the set value inputs 20 to 23 for the corre­sponding values. (see table below) Cable cross-sectional
area max. 1.5mm

Mind the conguration of the set value

The 4 – 20 mA current signal at the terminals 30, 31 can be
evaluated, if necessar y.
(4 mA: CLOSED; 20 mA: OPEN)

When the set value and the position indicator have been
connected, reconnect the actuator to the supply voltage (see
wiring diagram).

The positioner has been connected correctly, when the
green LEDs 1,2, and 4 light up green.
If the LED 3 lights red, the controller is not working (see
LED combination).
Check the connections if necessar y and make sure the
poling of the set input is correct.
