Design and principle of operation

Design and
operation
principle
of
The electropneumatic positioner is mounted
to pneumatic control valves and is used to
assign the valve position (controlled
variable x) to the control signal (reference
variable w). The DC control signal received
from a control unit is compared to the travel
or rotational angle of the control valve and
issues a signal pressure (output variable y).
The positioner is designed depending on the
corresponding accessories for direct attachment to Type 3277 Actuators or for attachment to actuators according to IEC 60534-6
(NAMUR).
Additionally, a coupling wheel included in
the accessories is required to transfer the rotary motion for rotary actuators according to
VDI/VDE 3845.
Springless rotary actuators require an accessory reversing amplifier to permit the
powered operation in either direction.
The positioner basically consists of a travel
sensor system that functions proportional to
resistance, an analog i/p module with
downstream booster as well as the electronic
unit with a microcontroller. The positioner is
fitted with two adjustable software limit
switches as standard to indicate the valve's
end positions.
The position of the valve is transmitted as
linear travel motion or angle of rotation via
pick-up lever and travel sensor (2) to an analog PD controller (3). Simultaneously, an
A/D converter (4) transmits the position of
the valve to the microcontroller (5). The PD
controller compares this actual position to
8
EB 8384-1 EN
the 4 to 20 mA DC control signal (reference
variable) after it has been converted by the
A/D converter (4).
In case of a system deviation, the operation
of the i/p converter (6) is changed so that
the actuator (1) is filled or vented via the
downstream air capacity booster (7). This
causes the closure member of the control
valve to move to the position determined by
the reference variable.
The pneumatic air capacity booster (7) and
the pressure regulator (8) are provided with
supply air. An intermediate flow regulator
(9) with fixed settings is used to purge the
positioner and also guarantees trouble-free
operation of the pneumatic booster.
The output signal pressure supplied by the
booster can be limited to 2.4 bar by activating the parameter P9.
The volume restriction Q (10) is used to optimize the positioner by adapting it to the actuator size.
Tight-closing function:
The pneumatic actuator is completely filled
with air or vented as soon as the reference
variable falls below 1 % or exceeds 99 %
(see end positions set over parameters P10
and P11).

Attachment to the control
valve – mounting parts and
accessories
The positioner can be attached either directly to a SAMSON Type 3277 Actuator or
according to IEC 60534-6 (NAMUR) to control valves with cast yokes or rod-type yokes
as well as to rotary actuators according to
VDI/VDE 3845.
For attachment to the various actuators, corresponding mounting parts and accessories
are required. These are listed with their order numbers in Tables 1 to 5.
On attaching the positioner, it is important
to observe the assignment between lever
and pin position according to the travels
listed in the travel tables.
The actual valve travel that can be achieved
is restricted by the pin position used and additionally by the actuator spring compression required.
The travel range listed in the travel tables
opposite can only achieved if the nominal
range is set to MAX.
The positioner is standard equipped with the
lever M (pin position 35).
Note: If the standard mounted lever M (pin
position 35) is replaced, the newly mounted
lever must be moved once all the way as far
as it will go in both directions to adapt it to
the internal measuring lever.

Refer to Table 1 on page 29 for the required
mounting parts as well as the accessories.
Note the travel table on page 13!
Actuator with 120 cm²
Depending on the type of positioner attachment, the signal pressure is routed either left
or right of the yoke through a bore to the
actuator diaphragm. Depending on the
fail-safe action of the actuator "Actuator
stem extends" or "Actuator stem retracts"
(valve closes or opens if the supply air fails),
the switchover plate (9) must first be attached to the actuator yoke. Align the
switchover plate with the corresponding
symbol for left or right attachment according
to the marking (view looking onto the
switchover plate).
1. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
onto the positioner, making sure both
seal rings (6.1) are seated properly.
2. Remove screw plug (4) on the back of the
positioner and close the signal pressure
output (38) on the connecting plate (6) or
on the pressure gauge bracket (7) with the
stopper (5) included in the accessories.
3. Place follower clamp (3) on the actuator
stem, align and screw tight so that the
mounting screw is located in the groove
of the actuator stem.
4. Mount cover plate (10) with narrow side
of the cut-out opening (Fig. 4, on the left)
pointing towards the signal pressure
connection. Make sure that the bonded
14
EB 8384-1 EN
gasket (14) points towards the actuator
yoke.
5. 15 mm travel: Keep the follower pin (2)
at lever M (1) on the back of the
positioner in the pin position 35 (delivered state).
7.5 mm travel: Remove the follower pin
(2) from the pin position 35, reposition it
in the bore for pin position 25 and
screw tight.
6. Insert formed seal (15) into the groove of
the positioner housing and the seal ring
(10.1) on the back of the housing.
7. Place positioner on the cover plate (10)
in such a manner that the follower pin
(2) rests on the top of the follower clamp
(3). Adjust the lever (1) correspondingly
and open the positioner cover to hold
the positioner shaft in position at the cap
or the switch (Fig. 14).
The lever (1) must rest on the follower
clamp with spring force. Mount the
positioner on the cover plate (10) using
the two fixing screws.
Note for all types of attachment except for
direct attachment to Type 3277-5: The signal pressure output at the back must be
sealed using the screw plug (4, order no.
0180-1254) and the associated O-ring (order no. 0520-0412).
8. Mount cover (11) on the other side. Make
sure that the vent plug points downwards
when the control valve is installed to allow any condensed water that collects to
drain off.

5.1.1 Signal pressure gauges
To monitor the supply air (Supply) and signal pressure (Output), we recommend that
pressure gauges be attached (see accessories in Tables 1 to 5).
d = Seat diameter [cm]
∆p = Differential pressure across the valve
[bar]
A = Actuator diaphragm area [cm²]
F = Upper bench range of the actuator
[bar]
5.1.2 Supply pressure
The required supply air pressure depends on
the bench range and the actuator's operating direction (fail-safe action). The bench
range is registered on the nameplate either
as spring range or signal pressure range.
The direction of action is marked FA or FE,
or by a symbol.
Actuator stem extends FA (Air to open
ATO)
Fail-safe position "Valve Closed"
(for globe and angle valves):
Required supply pressure = Upper bench
range value + 0.2 bar, minimum 1.4 bar.
Actuator stem retracts FE (Air to close ATC)
Fail-safe position "Valve Open"
(for globe and angle valves):
For tight-closing valves, the maximum signal
pressure pstmax is roughly estimated as follows:
pstmax = F +

The volume restriction is used to adapt the
air delivery to the actuator size. Two fixed
settings are possible depending on how the
air is routed at the actuator. See section 7.1
for more details.
Display
The LC display indicates icons that are assigned to codes and functions. The bar
graph indicates the system deviation that depends on the sign (+/–) and the value. One
bar graph element appears per 1 % system
deviation.
If the positioner is not initialized, the lever
position in degrees in relation to the longitudinal axis is indicated instead of the system
deviation. One bar graph element corresponds to approximately a 5° angle.
If the

Start-up
WARNING!
Attach the positioner, keeping the following
sequence:
1. Remove protective film from pneumatic
connections
2. Mount the positioner on the control valve
3. Connect the supply air
4. Connect the electrical power
5. Perform the start-up settings
For most applications, the positioner is
ready for operation with its default settings,
provided it is attached properly.
The positioner just needs to be initialized after the volume restriction has been set and
the fail-safe position has been determined.
WARNING!
Do not perform a start-up while the process
is running.
On applying supply air and the electric control signal, the control valve may move
through its entire travel range/rotational angle range depending on the setting.
Note: The positioner has a function to monitor the working range.
If the lever moves too close to the mechanical stops (risk of mechanical damage), the
positioner vents the actuator and the valve
moves to its fail-safe position (S displayed
together with error code E8 or E9).
In this case, check the positioner attachment.
Reset the displayed error code using RST
(see section 7.6.)

The volume restriction Q is used to adapt the
air delivery to the size of the actuator:
4 Actuators with a transit time < 1 s, e.g.
4
linear actuators with an effective area
smaller than 240 cm², require a restricted air flow rate (MIN).
Actuators with a transit time ≥ 1 s do not
require the air flow rate to be restricted
(MAX).
The position of volume restriction Q also depends on how the signal pressure is routed
at the actuator in SAMSON actuators:
* Intermediate positions are not permitted.
Note: The positioner needs to be initialized
again after the position of the restriction has
been changed.

Initialization
During initialization the positioner adapts itself optimally to the friction conditions and
the signal pressure demand of the control
valve.
The type and extent of self-adaptation depends on the preset parameters.
MAX is the default setting for the nominal
range (Code P4). During the initialization
process, the positioner determines the
travel/rotational angle of the closing element from the CLOSED position as far as it
will go in the other direction.

Start-up
Note: For standard operation, after the
positioner is mounted on the valve and the
volume restriction has been set and the
fail-safe position has been checked over
Code P2, start initialization over Code P15
to ensure the optimal functioning of the
positioner.
The positioner works with its standard settings (default settings).
WARNING!
During the initialization, the control valve
moves through its entire travel/angle of rotation range. Therefore, do not start initialization while a process is running, but only
during start-up, when all shut-off valves are
closed.
Start initialization by activating Code P15
as follows:

the pneumatic connections for supply and
output which can be removed and cleaned,
if required.
The maintenance instructions of any upstream supply air pressure reducing stations
must be observed.

Servicing explosion-protected
devices
If a part of the device on which the explosion protection is based needs to be serviced, the device must not be put back into
operation until a qualified inspector has assessed it according to explosion protection
requirements, has issued an inspection certificate or given the device a mark of conformity.
Inspection by a qualified inspector is not required if the manufacturer performs a routine test on the device prior to putting it back
into operation. The passing of the routine
test must be documented by attaching a
mark of conformity to the device. Replace
explosion-protected components only by
original, routine-tested components from the
manufacturer.
Devices that have already been operated
outside hazardous areas and are intended
for future use inside hazardous areas must
comply with the safety requirements placed
on serviced devices. Before being used inside hazardous areas, test the devices according to the specifications for servicing
explosion-protected devices.
