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 20mA) and the output is a
pneumatic signal, for example, 0.2 to 1bar
(3 to 15psi) or signal ranges up to 8bar
(116psi).

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
20mA have a slide switch which activates
the switch-off electronics. This function allows
the input signal to be set to 0mA when the
signal falls below the switching point of
4.08± tolerance. This causes the pneumatic
output to be vented to approximately
100mbar. 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 20mA/0.2 to 1bar.
If the characteristic line does not pass
through zero, for example, for an allocated
output signal from 0.8 to 2.7bar, then the
pneumatic output is vented to a remaining
pressure of approx. 0.3bar when the
switch-off electronics are activated.

3.1 Mounting position
The converter is to be installed horizontally,
with the pressure gauge (or screw plug) fac-
ing upward. If a different mounting position
is used, the zero point must be readjusted as
described in section4.1 on page10.
With degree of protection IP54, the vent
plug must always be installed facing down-
ward to the oor.
3.2 Mounting
The converter can be mounted to a wall, a
pipe or directly to a control valve (Fig.4).
The following accessories are required:
Order no. 1400-6216
−For wall and pipe mounting
Order no. 1400-6217
−For attachment to valve with cast yoke
Order no. 1400-6218
−For attachment to valve with rod-type
yoke

3.3 Electrical connection
DANGER!
Risk of electric shock and/or the for-
mation of an explosive atmosphere.
For electrical installation, observe the
relevant electrotechnical regulations
and the accident prevention regula-
tions that apply in the country of use.
In Germany, these are the VDE regulations
and the accident prevention regulations of
the employers’ liability insurance.
DANGER!
Adhere to the terminal assignment.
Switching the assignment of the elec-
trical terminals may cause the explo-
sion protection to become ineffective.
Do not loosen enameled screws in or
on the enclosure.
The following regulations apply to installa-
tion in hazardous areas: EN60079-14
(VDE0165, Part1) and DINEN50281-1-2
(VDE0165, Part2).
The maximum permissible values specied in
the EC type examination certicates apply
when interconnecting intrinsically safe elec-
trical equipment (Ui or U0, li or I0, Pi or P0, Ci
or C0 and Li or L0).
WARNING!
Leakage to the terminal space leads
to the degree of protection not being
met.
Only operate the device with sealed
cable entries and locked cover.

Fig.5: Electrical connection
1. Unscrew the enclosure cover and connect
the wires for the input signal to the termi-
nals 11 (+) and 12 (–) using suitable ca-
ble glands or connectors.
No additional voltage supply is required.
Connect Exd versions with an approved
metal cable entry (certicate of conformi-
ty) or a seal box pipe.
Approved versions (certicate of confor-
mity) are equipped with permanently
sealed cable entries.
2. Secure grounding conductor at the
ground terminal located either inside or
outside the enclosure.
3. Check the O-ring for damage and re-
place it, if necessary.

Operation
through and clean all air pipes and hoses
thoroughly before connecting them.
NOTICE
Risk of property damage due to wa-
ter entering the device when a pipe is
used to extend the vent pipe.
Make sure that no water can enter at
the end of an extension pipe (mini-
mum cross-section of 28mm² =
6mm inside diameter) connected to
either vent elbow piece or directly to
the G or NPT connection.
4 Operation
See Fig.2 on page 6.
4.1 Checking zero and span
The device converts the input signal propor-
tionally into the output signal.
The signal ranges are specied on the name-
plate.
In case of a mounting position that is not
horizontal or when the pressure gauge/
screw plug does not face upwards, zero and
span can be corrected by approx. 10% us-
ing the electronics. To do this, proceed as
follows:
1. Unscrew the enclosure cover to access
the ZERO and SPAN potentiometers (4)
on the circuit board.
2. Connect a pressure gauge (minimum ac-
curacy class 1) to the converter output.
4. Screw on the cover as far as it will go.
Unscrew the cover until the rst possible
safety position (notch) is reached.
5. Unscrew the llister head screw to lock
the cover.
NOTICE
Loss of Exd protection due to dam-
age to the cover's thread and/or the
connecting thread. The enclosure
cover must be rmly closed during
operation.
3.4 Pneumatic connection
The pneumatic connections for supply air
(SUPPLY 8) and output (OUTPUT36) are de-
signed as threaded ports with G¼ or
¼–18NPT thread (see section11 on
page25).
Customary ttings for metal tubing or plastic
hoses can be used.
Supply air (see section9 on page20).
−Min. + 0.4bar above the upper signal
pressure range
−Max. 10bar·Type6116-2: max. 6bar
(see EC type examination certicate in
Appendix)
Note:
The supply air must be dry and free
of oil and dust (see section9 on
page20).
Read the maintenance instructions for up-
stream pressure reducing stations. Blow
