 Erection, installation and
Commissioning of the Control
Karlsruhe GmbH System
0-7505 Ettlfngen

The erection, installation and commissioning of the control

system is only part of the WIEGAND supply if this was "explicit-
ly mentioned in the confirmation of order. The same applies
for all electric instruments as well as for the pump motors.
If this was not especially agreed upon, it will belong to
the customer's supply in any case.

general (Control Elements)

The control elements (control valves acd control flaps)
are mostly mounted together with the evaporating plant.
In doing so, the following will have to be checked and
observed:
a) correct installation, according to the flow direction
marked on the outside,
b) nominal widths of flow of the pipings are mostly
larger than those of the control elenents
c) the control elements have to remain free from inside
contamination
d) the piping will have to be supported such that the
control elements can be installed and removed without
problems
e) note the input section on the erection drawing if
indicated by us

B) PRECISION CONTROL INSTRUMENTS

i The installation of precisioit control instruments, such
as transmitters, sensors, and pontrollsrs should only be
started after completion of . all construction, painting
and rough locksmith works in the, evapcarator room and
after removal of all scaffolds ,' in order to avoid damages,

I- Transmitters (measuring transducer^ Sensors

In this connection, please note the indications on our
drawings. The instruments will have to be installed
free from vibrations close by the measuring section.
The connection between measuring point and transmitter
is called pulse line.
Important;
1. provide a syphon for the steam pressure transmitter
2, do not provide a syphon for the vacuum transmitter,
install it lo cm above the measisring point (pulse
line being a copper tube of 12 Em length) . Lay this
tube with an inclination to the measuring point.
For both a.m. transmitters a shut-off cock will have
to be mounted in the pulse line. Do not brace measuring
point and transmitter with the pulss line. Leave sorre.
space for a later insulation.

3. Install the temperature transmitters, sensors

in reverse current and dip thera into the liquid flow
in their total length.
4. Screw in the electric resistance thermometers
with special care.
5. The flowmeter will have to be absolutely mounted
with the fixings provided for and in accordance
with our erection drawing. In any case, it has to
be avoided that pre- or subsequently arranged
tube sections are fixed at the flowmeter. If necessary,
these tube sections have to be fixed separately.
There must be the possibility to install and remove
the flowmeters quickly and without problems, without
impairing pre- or subsequently arranged tube
sections.
6. Screw in and tighten the conductivity measuring cells
in the tube bend as indicated.
Attention: Do not turn the electric connecting head
of the measuring point- (danger of damaging
it) . Only use existing hexagon.
7. Density measuring instrument
It is of particular importance that no vibrations
are transmitted by the pump which ,is normally pre-
arranged. If this is not possible, flexible
connections will have to be provided for. Density-
meters will have to be fixed to a firm foundation.
Compensators of oscillation are not allowed.
»

All places of installation/of transmitters have to be

checked on that
a) no impairment of the instruments can take place by
dripping and splashing'liquids or steam,
b) they are mounted outside areas which are frequented
by public or the opiating personal.

II. Control Panel

1. The control panel v;ill have to be mounted on

the foundation prepared by the customer.
The control panel is to a large extent pre-
assembled, pneumatically tubed and electrically
wired.

2. The WIEGAND supply contains the following

control instruments which, for reasons of
transportation can only be mounted into the
control panel on site:
- compact indicator
- compact controller
- six-colour point printer
- three-line recorder
3. These instruments will have to be inserted and
clamped in t>E control panel with the aid of
the control panel drawing. Make the connections
between the indicators, controllers, six-colour-
point printers and line recorders and the lines
pre-assembled in the panel from the pneumatic
and electric connecting block to the controllers.
Use our drawings for this purpose.

C) AIR SUPPLY (Pneumatics)

1. Connect ion, compre ssor with supply a ir reduc ing
station and filter station.
A suitable, accessible 'space outside the control
panel has to be chosen for the air reducing station.
Please note that air will have to be conveyed
directly from the supply air reducing station into
the control panel and into the plant. The connection,
compressor with supply air reducing station will
have to be laid by t^e customer using a metal tube
of 1/2

2. Connection, air reducing station with the control

panel will have to be carried out by the customer,
using a metal tube of 1/2" or a plastic hose which
is resistant to compression (10 atue).

3. Connections, air reducing station with air

distributor for transmitters, change-over valves
and positioner controllers at the controlling units
have to be made as described under paira: 2.
4» Connections of the pneumatic connecting block
in the control panel with the control valves and
transmitters as well as change-over valves

a) with small plants concerned, individual lines

will have to be laid, see pneumatic diagram
b) with bigger plants concerned, the pneumatic
multi-strand collective cable from the control
panel to the individual air distributors in the
plant will have to be used.

Note ; We recommend to lay the spare circuits at the

same time.
- supply air distributors (see para 3) and signal
air distributors will have to be mounted on
a protected spot in the plant and must be
easily accessible.
- they should, be arranged close by each other
- when chosing their location, one should
take care that the connecting lines with the
transmitters, change-over valves and control
elements are as short as possible.

5. The connecting lines between supply air distributors

(feed air for the transmitters) will have to be
inserted, consisting of a plastic hose, 1/4" and
6 mm, of blue colour. At the same time, the signal
lines between the transmitters and the signal air
distributor will have to be inserted, consisting
of a plastic hose, 1/4 " and 6 mm, of black colour.

6. Make the connections ^tween signal air distributor

and control elements (control valves, control flaps),
change-over valves by means of a plastic hose of 1/4"
and 6 mm, of red colour.
At the same time, the ;feed air supply lines for the
positioner controllers at the control elements will
have to be laid. Here too, a plastic hose of 1/4"
and 6 mm, of blue colour, will be used.
a) If there is no sCipply air distributor for the
positioner controllers in the plant, the air
is directly taken from the air reducing station,
see the pneumatic diagram for this purpose.
b) If there are several positioner controllers,
a separate supply air distribution is provided
for (in addition to the two distributors
mentioned under para 3 and 4b) .

D) E^RECTIQN OF THE ELECTRO PART

If not especially agreed upon, these works do not form
part of our scope of supply

In particular, the following will have to be installed

(according to the electric and pneumatic WIEGAND diagrams) ;

I. General
1. Connecting lines between the electric panel part
(contactor panel) and the p\amp motors of the
evaporating plant•
2» The connecting line between the electric panel part
(contactor panel) and the. fan motor of the cooling
tower, particularities of installation of the stator
heating of the motor will have to be observed.
3. The connecting line from the electric panel part
(contactor panel) to the cooling tower heating
(for this purpose, please see our electric wiring
diagram) •

4. The connecting line from the electric panel part

(contactor panel) to the bowl heating thermostat of
the cooling tower and to the fan motor thermostat.
The former will be fixed in the cooling tower' bowl
and prevents the cooling water from freezing, the
latter should be fixed to an outside wall of the
cooling tower building* The stator heating will be
brought into action at an outside temperature of
- 15
5. The control lines from the WIEGAND control panel
to the electric panel part (contactor panel) for the
pump motors.
6. The connecting line t^tween water-flo\>? detector after
the sealing water tanTc and the control panel.

7. Connecting lines between control panel and damp proof

distributor cap within the evaporating plant,
connecting lines between distributor cap and
illuminating hoods for the separator illumination.
8. The electric measuring lines of the resistance
thermometers to the control panel. For this a copper
wire, twined, 2 x 1,5 mm^, will be required. The
lines will have to be equalized (in this connection
please see the operating instructions of the
electric temperature recorder).

!!• If provision is made for an electric control system

1. Lay the connections, transmitter with control

panel by^means of twined copper wire of 2 x
1,5 mm^.
2. If pneumatic valves with electric positioner
controllers are applied, twined copper wire,
2 X 1,5 mm^, will have to be laid for each
positioner controller from the connecting block
in the control panel to the individual positioner
controllers at the pneumatic valves.

3. care has to be taken that the signal lines

from the transmitters to the connecting block
in the control panel and from the connecting
block in the control panel to the valves are
laid in steel-armoured conduit and that no
power circuits are nearby which might cause
inductive voltages.

4. If electric control valves are used a four-strand

line will have to be laid in addition from the
control panel to the control valves. This is a
power circuit, the cross section of which will
have to be selected according to the respective
drive.

COMMISSIONING
As soon as the erection of the measuring and control in-
struments as well as the supply air reducing station and
the individual air distributors is completed and all con-
nections are made, the commissioning will be started.
The following sequence shall be kept tO:

I. Checking of the Air Supply

1. The connections between the air reducing station and

the control panel will be loosened at the air dis-
tributor in the control panel. The same is done with
the individual connections at the air distributors
in the plant.

2. Start the compressor and let the air blow for about
3 hours, so that the supply air piping will get clean.
Attention; Avoid that oil containing air gets into
the control instruments when you start the
system. This would make necessary consider-
able repairing works.

3. Tighten the loosened unions again.

II. Adjustment of the Air Supply (Supply Air at the Air

Reducing Station) »
«

The individual instruments'have to be supplied as des-

cribed below:

1. Positioners at the control valves with 2.5 atm.g.

2. Change-over and spray cleaning valves with 4 atm.g.
3. Pressure, absolute pi'essure, and temperature trans-
mitters, density me^uring instrument, flowmeter, and
controllers with 1.35 - 1.4 atm.g.

Attention: These values must individually be checked

at the input of the respective instruments
by means of a hand manometer (loosen the
supply air line at the individual instru-
ments) .

III. Preparation of the Control System (Positioners, Trans-

mitters, and Controllers) for the Start-up
1. Adjust all controllers to manual operation. Remove
the transport safety devices in the controllers, trans
mitters, densitymeter, and flowmeters as described in
the attached operating instructions.

Karlsruhe GmbH Commissioning of the Control
D-750S Ettllngen System

2. By means of the manual controllers of the individual

auto-manual stations at the controllers the respective
valves are passed in the whole range. That means, a valve
for steam has to be closed when the control capacity is
O %, it has to be open by 50 % when tlie control capacity
is 50 %. The control capacity is adjusted at the manual
controller of the auto-manual station.

3. When the control elements are. equipped with positioners

the positioners must be checked according to the operating
instructions attached and, if necessary, they must be re-
adjusted. It has to be taken care, that the closing and
opening velocities of the control elenents with positioners
are the same. This can be regulated at the spring tension
for the control element.

4. When the controUers are adjusted to "manijal", the valves must

be checked as follows:
a) Manual controllers at the controllers to 50 %. The valve
must be opened by 50 %.

b) Repetition at O % and lOO With O the valve must be

closed and at 100 % it has to be completely open. This
applies to the steam valve only. As far as the other valves
are concerned, you will have to look at our drawings for
the control technique where we stated the required safety
positions of the valves; i.e. whether the valve has to be
closed without pressure or opened without pressure.
»

5. If the values stated under item 3 cannot be repeated, please

check:
/

a) the control capacity output'of the controller - this out-

put must be measured directly before the valve.
b) If a) is correct, check th^ control element.

Start-up of the Plant

Now everything is ready to start the measuring and control
system of the plant.

When you start up the plant, you have to take care that the
rectifiers of the indicating instruments and the motors of
the recorders are supplied with electricity and that all the
controllers are switched on manual operation. Now the plant
can be started on water.(see general operating instructions
for the evaporator) .

I With the manual controllers at the individual controllers

the valves will be adjusted in such, a way that the
required values for steam, pressure, temperature, and
feed are obtained. As soon as those; values are obtained,
and after' a time of about 10 minutes, the set-point de-
vices will be adjusted in such a way that the output
signal of the controller equals the output signal of the
manual controller.is giving to the valves. Those figures
will be indicated at the controller. •

II. Criteria for the adjustment of the controllers

steam pressure control loop - proportional range = 80 %,

reset time: 0.2 min.
vacuum control loop - proportional range = lOO %,
reset time: 0.5 min.
temperature control loop - proportional range = 80 %,
reset time: 1.5 min.
feed control loop - proportional range = 100 %,
/ reset time_^ 0.3 min.
level control loop - proportional range = 50 %,
reset time: 1.0 min.
concentration control loop - proportional range = 400 %,
reset time: 6.0 min.

III After the adjustment of the approximate control para-

meters stated under II, the manual-automatic switches
at the individual auto-manual stations will be manually
switched over to automatic.
Attention; When it is switched over from manual to auto-
matic, the actual values^ and the set-points
must correspond; if they do not correspond,
the direction of the action has to be changed,
as described in the instructions for the spe-
. cific instrument. If there are still differen-
ces between actual values and set-points with
correct direction of the action, the zero points
at the controllers must be changed as per oper
operating instructions for the controllers.

IV When this has been done and when the temperatures in the
plant have reached the values specified, the product
feed can be opened and the plant is now run on product.

V The zero points for concentration end viscosity at the

respective transmitters (measuring transducers) can only
be adjusted during operation with product according to
measurements in the laboratory. That means for instance
for the concentration: a certain content of % TS will be
determined with the help of a pocket refractometer, If this
/ value corresponds to the vplue given by the indicator at
i the controller, it is moment;arily ijot necessary to correct
anything. If the controller-indication, however, differs
from the refractometer indication, it will be necessary
to correct the zero point at the transmitter (measuring
transducer) according to tHe instructions for the parti-
cular instrument.
Example: by means of the steam pressure the plant will
be run in such a way that an outlet concentration of
45 % TS which had been indicated on the refractometer
is obtained. After a period of aboat lO minutes, the dry
substance content in the product outlet shown on the in-
dication is still 45 The indication at the controller
itself, however, does only show 3 0 % TS. Now, it is ne-
cessary to correct the concentration with the zero-point
screw at the transmitter (measuring transducer) as des-
cribed in the instructions for the instrument, so that
the indication at the controller dees also state 45 % TS.
This can only be done, when the coatroller is switched
on manual operation.

The above-described correction can be repeated later,

i.e. it can be improved by comparisons with laboratory
measurements.

VI It is a precondition for a correct operation of the

control system, that the optimum controller adjustments
are found and realized during the first operation,
(see enclosure) .

VII Optimum Controller Adjustment

1. For the adjustment of the controller to the control

section it is necessary that the preparations des-
cribed in the instructions "Erection, Installation,
and Commissioning of the Control System" are completed.

2. All the control instruments will be checked and cali-

brated by the different companies before they are supp-
lied. The calibration is an optimum 95 % calibration.
In most cases this is the best calibration possible,
because the calibration is done on a production line.
The calibration may afterwards be changed due to trans-
port and weather conditions. The basic calibration is
mostly sufficient, because the controller adjustment;
methods of today only give approximate values. As far
as control sections for which the normal basic calibra-
tion is not sufficient are concerned,- these may be
4th class.control secti6ns.-, it is necessary to carry
out a second optimum cali,bration. This has to be done
as described in the operating instructions for the res-
pective instrument.

3. Adjustment of the contfoiler to the control section

We know different methods of adjusting a controller to
the control section, toe of the most simple methods
which is mostly used is the method found by Ziegler
and Nichols. In the most cases, this method brings abou^
the success required. All the methods known give appro-
ximate values only, guaranteeing an optimum 90 - lOO %
adjustment, it may only be necessary to an unimportant
correction not requiring any considerable adjustment.
It is not possible to determine a 100 % adjustment of
the controller.
When the class of the control section shall be deter-
mined, one has often to rely on assumptions, so that
in practice there are only approximate reference points
for the adjustment available. Even, if the data for si-
milar sections are available, it may be necessary due
to differences which cannot be seen from the outside
' to have different adjustments of control sections which
are equal for the rest. The methods known up to
to adjust a controller to the control section have been

Karlsruhe GmbH Commissioning of the Control
D-7505 Ettlingen System

either been determined by calculaticQ or by tests with

certain control systems.

4. Method of Adjusting the Controller

The controller must function as a pire P-controller.
For that purpose, the Tn-throttle (integral action) has
to be closed and the Tv-throttle (derivative action) has to
be opened. If the derivative action is not existing, it
is not necessary to open the Tv-throttle. Subsequently
you adjust a larger P-range (proportional) of approximate-
ly 500 With this position of the controller, you
now have to cause a sudden disturbance by changing the
set-point. As a result of this action, the control value
(actual value) which has to be seen on the recorder,will
change. Shown in a sketch, this will presumably look
like.figure "a".

a)

Zeii t

b)

Zeii t

Then, the proportional b^nd will be changed in a down-

ward direction and a disturbance is repeatedly caused by
changing the set-point until the recorder fig. IVb" shows
the control value. Now, the criticciE P-range Xpk is reach-
ed- This critical P-range can be read at the P-range ad-
justment of the controller. The valce resulting will be
multiplied by two and , thus, the P-range to be adjusted
is determined.

The whole time for the curve Tk as shown on fig. "b"

will be multiplied by 0.85, thus, determining the reset
time Tn. To find out the D-action (derivative time) , Tk
will be multiplied by 0.5.

The above-described method should lead to a good adjust

ment of the controllers.

H) ASSEMBLY AND ADJUSTMENT OF POSITIONER CONTROLLERS

The positioner controller is a proportional follow-up
controller. The output signal of the process controller
is the input signal of the positioner and thus it can
at the same time be considered the nominal value for the
follow-up control loop - in our case the positioner con-
troller.

The positioner controller shall be installed as described

in the assembly instructions attached. The assembly in-
structions always refer to a certain make. When the
positioner controller is installed at .the correcting ele-
ment, it will have to be adjusted. Please follow the
below stated sequence.

1. Open the supply air valve and check the air pressure.
The correct supply air pressure can be taken from
the type plate of the respective instrument. If the
pressure is not stated, choose a pressure of 4 bar g.

2. The action type of the positioner controller depends

on the required safety position of the correcting ele-
ment .

3) The input signal for the positioner can either be an

electric or a pneumatic signal - depending on the con-
troller make installed. By means of the range and zero
point devices the positioner must be adjusted such that
the correcting element is closed or opened — depending
on the action chosen - by*25 % when the input signal
is 25 With an input sigr^al of 50 %, the correcting
element must be opened by 50 %. With an input signal of
75 %, the correcting element must either be opened or
closed by 75 % - depending on the type of action chosen
When the instrument is adjusted, check all fastening
elements once again and control the correcting range.
(For a better understanding, please see the explanation
to the diagram.;H = lifi: of the correcting element,
y = input value for the positioner. H + y indicated in
percent)

G) ASSEMBLY OF SHUT-OFF AND CONTROL FLAPS

General
Flaps will be installed between the tube flanges. As the
flap disc is centrically located, the flaps can be in-
stalled independently from the throughput direction. To-
tal solids containing media form exceptions.For those
media we recommend to install the flap with horizontal
shaft with the lower half of the flap opening in the through-
put direction.
If the seat ring of the flap is provided with a sealing lip,
which is simultaneously forming a flange joint, it is not
permitted to use additional flange gaskets.

Installation
The flap will be shifted inbetween the flanges? at this time
the flap is almost closed (30^) . The flanges should be
drawn asunder so that the flap can easily be installed with
clearance. Afterwards, the. flange screws will be inserted
and the flap centered as well as adjusted. After a test
switching the screws will be tightened. .At new plants the
screws will have -to be tightened by hand and the flange
pinchwelded. The flap will then be dismantled again and
the flange weld completed. Only after the flange has cooled
down, will the flap be assembled again between the flanges.
Before the flange screv/s are equally tightened, a test
switching shall guarantee that the flap disc can move in the
connection flange. Orientatibn means are key surfaces and
the feather nut of the flap sh'aft resp., they must always
lie in parallel to the flap disc.

T Y P E : Compact pneumatic rotary actuator set for 90® rotation.

R A T I N G : Maximum pressure up to 9 bars.

R A N G E: Operating pressure range: Air to air 1.5-8.0 bars

Spring to air 4 . 0 - 8 . 0 bars.

G E N E R A L A P P L I C A T I O N : Specially designed for direct

mounting on Keystone Butterfly Valves to ensure reliable
remote operation under the most severe working condi-
tions. Also suitable for remote control of other quarter
turn devices.

FEATURES:
e R A C K A N D PINIOW system guarantees a
constant output torque during a complete valve
cycle thus making it more suitable for throttling
control applications. Type 7 9 0 - 1 0 0 and 7 9 0 -
140 have scotch yoke mechanism.

• H O U S I N G is deep black hard-anodized alumi-

nium making the actuators suitable for corrosi-
ve surroundings, including salt spray environ-
ments.

o ACETAL LUBRICATED output shaft supports.

Bearings provide longer life w i t h a minimum of
maintenance.

e Because of the simple piston drive c o n c e p t ,

this actuator requires less dynamic seals in
operation than the more popular types currently
available. This means less chance for air
leakage.

o D I R E C T M O U N T I N G to Keystone butterfly
valves eliminates specially made adaptations
and guarantees proper alignment w i t h the
valve-stem. This reduces assembly time and
possible damage through bad installation.

1. C<ai8truction and mode o f operation

Itie pnexmatio positioner assiires a
preselected relationship betveen the
i ^ v e stea position (controlled variable)

K
and the controller output signal (signal
input). I t ccnpares the output signal
of a pnetaatic or electropaeumatic
control device to the control valve
position and controls the output
pressure connected to the poeuiBatic
actuator.
The positioner essentially consists
•
of a lever with shaft sad measureoent
spring, the diaphragm and the jnematic
control system vith nozzle, flapper
plate and a i ^ l i f i e r . * - 1 ,
"Bie type 765-^ version has aulditional
aanoiaeters for output pressiire and
input prassure. Figure 1: Type 765
The positioner operates on the force balance principle. The controlled variable *
i s the position of the final ctmtrol element, particularly the stroke of a control
valve. The input w is the output signal of a pneumatic controller. The output y of
the positioner i s the air pressure Pg^.
For every positiwi of the valve there i s a corresponding torsion o f the measuring
spring ( 3 ) . Whenever the actuator or valve stem plate (20) and the pin (1.1) move,
the lever (1) and other transfer elements ( 2 . 1 , 2 . 2 , 3.1) cause the spring (3) to
rotate and the spring torsion i s altered.
Tte input, a signal (p^) in the standard pneumatic range, produces a force on the
diai^agm (>4) which i s balanced by the torsion load of the spring (3). I f the signal
Pg changes, then the feeler pin (5.1) moves, "fte flapper plate (6) follows this
motion and influences the nozzle ( 7 ) .
The supply air i s piped to the pnei»atic amplifier (8) and flows via the Xp-throttle
(9) and the nozzle (7) against the flapper plate (6). A change in either the signal
input or the actuator position causes a pressufe change before and after the s ^ l i f i e r .
The output pressure p^t controlled by the an?>lifier (8) flows t h r o u ^ the adjustable
volume throttle (10) to the pneiaaatic actuator. Adjustable needle valves (9 and 10)
are used for optiaizatioo and stabilization of the positicm-control-loop.
The lever (1) and the measuring spring (3) contained within the positioner are
adaptable to the desired valve stroke and the span of the input signal.

U. Operation

U.I Coordinaticm of positioner and actuator

The position of attachment i s dependent on the type of actuator, of input signal and
o f the operating direction. Ihe mounting of the positioner has t o he arranged according
t o Pig. 7 to 10.
Each Buhsequent conversira such as, fo example reversing of operating direction of
the positioner or reversing of the actuator, "spring opening" to "spring closing"
actuator or vice versa, also means an alteration of the positioner's place of
attachment.

For an increase in the input pressure pg (signal input), the output pressure pat may
increase (direct action » ) or may decrease (reverse acti<Mi<>). Ihis is exactly the
saae for a decreasing input signal p^; in the case of direct a c t i m ^ , a decreasing
output pressure i s obtained and an increasing output pressure i s obtained in the case
of reverse actionO.
Itiere are lateral markings for the operating direction (>^and<>) ont the nozzle block
( 7 . 1 ) . One of the two markings i s covered by the angular tab of the covering plate
( 7 . 2 ) with the result that the v i s i b l e narking indicates which operating direction
has been set.
I f the desired operating direction (figures 7 to 10) does not agree with the v i s i b l e
marking or i f ^ e operating direction is to be altered, proceed as follows: unscrew
both screws (7.3) of the covering plate whilst holding the nozzle block. Benove the
cover plate.

H.2 Beginning of operation and signal input span

Each positioner contains a aeasurenent spring (1,2 or 3) ^ i c h can be adapted to the
desired valve stroke and the span of the input signal. Ohe lettering inside of the
cover specifies the relationship of the valve stroke and the signal input span A p.
Honnaly this i s 0.8 bar. A signal input span of O.^t bar i s only required for split
range operation. The range can be altered by subsequently replacing (section U.5)
the aeasurenent spring.
When adjusting the positioner, the stroke must be adapted to the signal input and
vice versa. In the case of a signal input span Ap of 0.8 bar ( e . g . froa 0 . 2 . ^ 1 bar)»
the stroke must also pass through i t s coi^lete range of 0...100^. n»e beginning of
operation i s then at 0.2 and the end value at 1 bsr. During s p l i t range operation,
the actuator operates with the lower sipial input span 4p of O.b bar. In this case,
the beginning of operation i s either at 0.2 bar or at 0.6 bar and, accordingly, the
end valxie i s at 0.6 or 1 bar.
The beginning of operation i s set with the screw ( 2 . 2 ) , the signal input span and
thus the end value i s set witti pin ( 1 . 1 ) . For adjuBt»ent, the control signal input E
Bust be linked to a coepressed air source with a maxinxn of 1.5 bar via a signal
pressure regulator and a control aancmeter and the supply air input Z must be linked
to an air supply.

U.2.1 Adfjusting the beginning of operation ( e . g . 0.2 bar)

(Refer also to section U.3}
Adjust the input pressiire t o a 0.2 bar beginning of operation the signal pressure
regulator. Turn screv (2.2) until the valve stes thus begins to aove fros i t s rest
position (observe the valve stea with travel indicator). Renove the input pressure
f r » the regulator and slowly increase once again. Check whether the valv« stem begins
t o Bove at' exactly 0.2 bar and, i f necessary, correct this.

or the atroke (Q...1001) ^ " ^
Once the beginning o f operation has been adjuated, increase the input pressure with
regulator t o 1 bar. At the end value of exactly 1 bar, the ralve stem aust be at a
standstill and must thus have passed throu^ 100* stroke. I f the end value i s not
correct, the pin (1.1) must be shifted as follows for correction:
S i i f t to the lever end > stroke increases
Shift to the point of rotation > stroke decreases
After correction, remove the input pressure and increase this once again. First of
a l l check the beginning of operation and then the end value. Repeat correction until
both values are correct.

>>.3 Ad.iuatBent of the P-band (Xp)

The Xp-throttle (9) is normally set to a lower value (open approximately 1 rotation).
In the case of unstable behaviour of the position control loop, the range oust be
increased. However*, remember that the end value of the signal input i s also altered
t y means o f subsequent correction. Therefore, after this, the beginning of operation
and the end value must be checked and, i f necessary, correct i t .

Ad-iustaent of the voltnw (Q)

In order to enable better adaptation of the positioner to the dynamic behaviotir of
smaller actuators, the air output capacity can be accordingly reduced from i t s maximum
value by means of the volume throttle (10).

Replaceaent of the Beaaurettent spring (figure 3)

I f the range is to be altered or converted to s p l i t range operation, the measurement
apring must be replaced as follows:
First of a l l unscrew screw (3.2) from the measurement spring, then release the screw
( 2 . 3 ) and remove the lever with shaft.
Replace the measurement spring, then place the lever with shaft t h r o u ^ the measure-
ment spring and bush with zero point adjustment (2.U). Secure the measurement spring
with screw ( 3 . 2 ) . Shift the bush and shaft towards each other so that the screw (2.3)
meets the flattened part of the shaft. Secure screw ( 2 . 3 h there should be a play
of 0 . 1 . . . 0 , 2 mm between the lever ( l ) , the spacer bush ( 1 . 3 ) , the measurement spring
(3) and the housing.

5. Use of the po8iti<»er as poeumatic aotion tranamitter (figure 12)

I f two derices are to be attached, f i r s t of a l l the place of attachment of the
positioner must be laid down in accordance with figures 7 to 10.
It i s then aaly possible t o attach the motion transmitter to the other side of the
valve. I f the relatiaiship of the input pressure Pg^ to the output signal p^ (figure

shifted by 180®. The valve travel i s then transferred via plate (20) from the attached
asseably to the other side of the valve stem (refer t o figure 13, figures U and 5 ) .
In order to enable attachment of the plate t o the valve stem, the coupling (22) must
be ranoved and the clamp without stay oust be replaced by a clamp with stay (refer
to section 7 . 2 . 1 ) for the order number).
I f the cou^ing consists of clanqo without stays with a indicator (figure 5 ) , an
additional indicator (order number 0.200-007'*) must be mounted for the second plate.
Proceed in accordance with sections U.2.1, 1».2.2 and 5 for adjustment of the

. 1 Possibilities of exchan^ng the Actuator

The lype 2Ul Valve can be eqiiipped with a Type 271 Pneumatic Actuator (with or
without handwheel), a Type 273 Hand-operated Actuator* or an Electric Actuator.
A pneumatic actuator (with or without handirtieel) can be exchanged for a pneumatic
actuator of different effective area in the case of nominal valve sizes of
to do nm. Tables 1 and 2 indicate which valve can be combined with which
actuator.
If the actuator (80 or 2140 cm^) for valves DH to 80 OOB i s exchanged for a
larger actuator (350 or TOO co^), also the coupling nut (6.1)and the coupling (7)
must be exchanged. The new co\q>ling to be installed i s supplied with the new
actuator ( i t is part of the actuator). "Die new coupling nut (having a top
diaiKter of 16 mm) and the pointer required in addition are included in an extra
package (Product Ho. 1.UOO-$310) attached t o the actuators 350 ci^ and 700 c ^ .

When valve and actuator are supplied separately, the dimension x has been adjusted
according t o Table Fig. 6. When the actuator i s mounted on the valve so adjusted,
a zero shift of up to + of the signal pressure range may occur due to the
actuator manufacturing tolerances.We, therefore, recomnend to check dimension x
upon assembly of valve and actuator using Table in Fig. 6 and, i f necessary,
adjust the coupling nut (6.1) as follows:
Loosen lock nut ( 6 . 2 ) , adjust coupling nut (6.1) in compliance with dimension x and
t i ^ t e n lock nut again.
Caution: The dimensions specified in the table are applicable only i f the springs
have not been pretensioned. In the case of an actuator vith pretensioned springs,
adjust valve as described in section 3.3.2

The Principle of
Measurement
The density measurement Is based on ^ ULlt ttt^illl
the absorption method. The radiation cooMng water cooling water
connaotion connection
emitted by an radiation source Is
attenuated by the product being mea-
sured. A detector measures residual
incoming radiation and delivers an
output signal dependent on radiation
intensity. The microprocessor unit Unadedpipe threactodptpe
connecMon
transforms the detector signal Into a connection SC6Snt18S1
current signal. The ^^'Am radiation
offers several advantages when used
In chemical production:

• The radiation attenuation depends V. -

A 1
on the atomic number of the ab- i
sorber If the concentration of a
material with high atomic number in
a liquid, (e.g., HCI, H2SO4, CaO, etc.
in water) must be determined, very
high measurement accuracies can na 2S0
be attained thereby. ^ wHh gfe^ coatInQ en- ail

Some examples:
H2O-HCI ± 0.022 % HCL Density measuring system with Flanged density measuring system
H2O-H2SO4 ± 0.038 % H2SO4 threaded pipe connection
H20-Ca(0H)2 ±0.017%Ca(OH)2 („milkpipe screw connection")
H20-Ti02 ± 0.014 %Ti02
NaHgO-NaOH ± 0.033 % NaOH
Low-fat milk ± 0.075 %TS
Starch suspension ± 0.085 %TS
Sugar solution ± 0.095 %TS

Chemical reactions In which materials 4 m

with high atomic number are depo-
sited can be monitored. This is possi-
ble even when no density change, or
