2 Description
2.1 Application
The devices (proportional valves) are used to
convert a direct current input signal into a
pneumatic output signal for measuring and
control tasks. They are particularly suitable
as an intermediate element between electric
measuring devices and pneumatic controllers
or between electric control devices and
pneumatic control valves.
The input is a load-independent direct cur-
rent (e.g. 4 to 20mA) and the output is a
pneumatic signal, for example, 0.2 to 1bar
(3 to 15psi) or signal ranges up to 8bar
(116psi).

General safety instructions
2.3 Principle of operation
See Fig.2 on page 6.
The device consists of an i/p converter mod-
ule and a downstream volume booster.
When operated, the supplied direct current i
ows through the plunger coil (2) located in
the eld of a permanent magnet (3). At the
balance beam (1), the force of the plunger
coil, which is in proportion to the current, is
balanced against the force of the dynamic
backpressure. The backpressure is produced
on the apper plate (6) by the air jet leaving
the nozzle (7).
The supply air (SUPPLY 8) ows to the bot-
tom chamber of the volume booster (8) and
a certain amount of air determined by the
diaphragm position ows past the sleeve (9)
and leaves through the output (OUTPUT 36).
As the input current and the forces acting on
the plunger coil increase, the apper (6)
moves closer to the nozzle (7). This causes
the backpressure and the cascade pressure
pK upstream of the restriction (8.2) to in-
crease until the cascade pressure corre-
sponds with the input current.
The increasing cascade pressure pushes the
diaphragm (10) and the plug sleeve (9)
downwards. As a result, the supply air caus-
es the output pressure pA to increase until a
new state of equilibrium is reached in the di-
aphragm chambers.
When the cascade pressure drops, the dia-
phragm moves upwards, releasing the plug
sleeve and thus allowing the output pressure
pA to escape through the venting (EXHAUST)
until the forces are equal again.
Switch-off electronics (see Fig.3)
Devices with an input range from 4 to
20mA have a slide switch which activates
the switch-off electronics. This function allows
the input signal to be set to 0mA when the
signal falls below the switching point of
4.08± tolerance. This causes the pneumatic
output to be vented to approximately
100mbar. This guarantees, for example, the
tight shut-off function of a valve.
This function requires a characteristic which
passes through the zero point, for example,
for the version with 4 to 20mA/0.2 to 1bar.
If the characteristic line does not pass
through zero, for example, for an allocated
output signal from 0.8 to 2.7bar, then the
pneumatic output is vented to a remaining
pressure of approx. 0.3bar when the
switch-off electronics are activated.

Maintenance
5 Maintenance
No specic maintenance measures need to
be carried out.
To guarantee trouble-free operation of the
converter, make sure that the supply air is al-
ways clean (see section9 on page20 for
air quality).
Therefore, check the air lter and trap in-
stalled in the upstream air reducing station
regularly.
5.1 Cleaning the restriction
The restriction (see Fig.11) is located inside
the enclosure. It can be accessed from the
back of the device. It can be taken out after
the screw plug (Ø10) has been removed.
When the output signal is too small or when
there is no output signal at all, the restriction
might be blocked. To remove blockages, take
the lter out of the restriction and clean or
replace it.

Order no.: 1390-0186
In addition, the pneumatic connections have
lters with plastic rims (order no. 0550-
0213) which can be removed for cleaning.
6 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 qualied inspector has assessed it ac-
cording to explosion protection require-
ments, has issued an inspection certicate or
given the device a mark of conformity.
Inspection by a qualied inspector is not re-
quired if SAMSON performs a routine test
on the device before putting it back into op-
eration. Document the passing of the routine
test by attaching a mark of conformity to the
device.
Replace explosion-protected components on-
ly with original, routine-tested components
from the manufacturer.
Devices that have already been used outside
hazardous areas and are intended for future
use inside hazardous areas must comply
with the safety requirements placed on ser-
viced devices. Before being operated inside
hazardous areas, test the devices according
to the specications for servicing explo-
sion-protected devices.

Positioner attachment
7 Positioner attachment
Analog positioners with Exd explosion pro-
tection can be implemented by combining a
p/p positioner with a Type6116-2 (Ex d)
Converter.
In the Type6116 Converter designed for po-
sitioner attachment, the connection to the po-
sitioner is used in place of the booster.
Another application involves upgrading p/p
positioners to electropneumatic positioners
(current signal input instead of the pneumatic
signal).

7.1 Principle of operation
When operated, the supplied direct current i
ows through the plunger coil (2) located in
the eld of a permanent magnet (3). At the
balance beam (1), the force of the plunger
coil, which is in proportion to the current, is
balanced against the force of the dynamic
backpressure. The backpressure is produced
on the apper plate (6) by the air jet leaving
the nozzle (7).
The air supply for the nozzle is taken from
the pneumatic positioner (connection to the
pneumatic input signal – input signal 27).

7.2.1 Mounting position of the
converter
The converter must be mounted horizontally
using the adapter with the cable entry facing
sideways away from the positioner or the
control valve.
Make sure the O-ring (10) to seal the enclo-
sure is inserted correctly.
7.3 Electrical connection
Connect as described in section3.3 and
Fig.5.
7.4 Pneumatic connection
Note:
Generally, the pneumatic connection
of the i/p converter is established by
connecting it to the pneumatic input
of the positioner.
For direct attachment to the Type3766-000
Positioner (Fig.8), the converter is connect-
ed using the hollow screw with grommet (6)
and threaded bushing (5). The second screw
(7) is used to vent the converter over the po-
sitioner housing.
Before attaching the adapter (8) to the posi-
tioner, remove the M20 screw plug and the
connecting nipple (input signal).
For Type4765 and Type3760 Positioners
(Fig.9 and Fig.10) the
1
/
8
NPT threaded
connection of the adapter (9) needs to be t-
ted with a suitable cable gland and must be
connected to the input connection (input sig-
nal 27) of the positioner using a pipe or
hose. Try to keep the connection as short
and small as possible, e.g. 6x1mm
cross-section.
The second bore (G¼) serves as vent and
needs to be equipped with the vent plug (11)
included in the accessories.
For all positioners, the connecting plate (1)
must be removed from the bottom of the
housing together with the sealing element
(1.1) and replaced with the parts delivered
(accessories). Make sure that the sealing ele-
ment is positioned correctly. The lter must


EB 6116 EN 15
Positioner attachment
be located in front of the restriction of the
connecting plate.
For Types4765 and 3766, attach the sili-
cone hose (4). For Type3760, put on the
cap (4) included in the accessories.
Refer to the mounting and operating instruc-
tions of the corresponding positioner con-
cerning the connections for supply air (SUP-
PLY 8) and output (OUTPUT 36).
7.5 Operation
Any adjustments to assign the travel of the
control valve to the electric input signal must
be made at the positioner separately from
the converter module. The necessary steps
are described in the corresponding mounting
and operating instructions.

Problem Possible reasons Corrective action to be
taken Comments
No output
signal despite
changing the
input signal
Supply air not connected Check supply air connec-
tion. See section3.3.
Incorrect terminal assign-
ment
Connect + and – termi-
nals correctly. See sec-
tion3.3.
NOTICE
i/p converter does not need
any extra voltage.
Incorrect input signal Connect correct signal. Read nameplate:
0 to 20mA or 4 to 20mA.
i/p converter
constantly vents
off air loudly
Connections for supply air
and output at the i/p con-
verter mixed up
Check pneumatic con-
nections. See sec-
tion3.4.
i/p converter
does not reach
100% output
e.g. 20mA
input: output
only 70%
instead of
100%
Supply pressure too low
Supply air must be
0.4bar greater than the
max. output signal.
Read nameplate: output 0.2 to
1bar → Supply air at least
1.4bar
Input signal faulty
Check whether the input
signal at the terminals
reaches 100% (100% is
e.g. 20mA in standard
version and 12mA for
split-range operation)
NOTICE
i/p converter has a load of
– max. 6V (standard version)
– max. 7V (Ex ia version)
Check specication concern-
ing permissible load at the
source of the input signal.
