4 Product description
4.1 Delivery package
Included in the delivery package of the device are:
• A device FD0-VC-Ex4.FF
• One product attachment (instruction manual, data sheet)
The following parts are not included in the delivery package of the device, however, can be requested free
of charge up to the number of devices ordered:
• Manual, German and English, incl. data carrier (disk 3,5" or CD) with device description file to integrate
the device into the engineering tool
4.2 System structure
The valve coupler FD0-VC-Ex4.FF is a field device for FOUNDATION fieldbus according to IEC 61158 and is
used to operate a maximum of four intrinsically safe low power auxiliary valves and a maximum of eight final
position feedback contacts (PFCs; NAMUR sensors or other mechanical contacts) within areas subject to
explosion hazards or areas which are not subject to explosion hazards at the H1 fieldbus. An auxiliary valve
is used as a pilot valve for one actuator which can be provided with final position feedback contacts to feed
back the drive position. The term valve as used within the manual means the overall chain consisting of
auxiliary valve, control drive and regulation unit.
For the H1 fieldbus a screened twisted two-wire cable is used. Via this two-wire cable the field devices are
supplied and data are exchanged. FF-H1 allows branches.
The manual and the software to integrate the device into the engineering tool is also available at
the Pepperl+Fuchs internet homepage www.pepperl-fuchs.com.
Other accessories see section 4.3 and product catalogue of Pepperl+Fuchs.

4.2.1 Device description
The valve coupler is accommodated in a housing for panel mounting. This housing may also be mounted
at a pipeline using specific accessories. The device has been designed for the ignition protection class "in-
trinsic safety" and can be arranged in the field subject to the approval. The connector terminals of the field-
bus are spatially and galvanically separated from those of the auxiliary valves and PFCs. LEDs on top of
the terminal blocks indicate the instantaneous status of the valve coupler locally.
• PWR (power): green (continuous light) = Supply voltage available
• COM/ERR: red (continuous light) = Hardware fault
red (flashing) = no bus activity or bus fault
• IN/OUT CHK: red (continuous light) =Fault code for a hardwarefaultdetected duringacceleration.
red (flashing) = Channel fault; for the cause of the fault refer to section 7.
For the wiring and evaluation of the final position feedbacks the 2:1 procedure is used which is described
in more detail in section 4.2.4.
Monitoring and diagnosis features are integrated in the field device. The valve couplercan record automati-
cally the lead breakages or short-circuits, carry out position dependent functional tests (cyclic function test,
section 6.5.7) and count the setting operations of the valve.
Commissioning is done in two steps. In the first step a "configuration wizard" aids during commissioning.
After demanding the type of drive used (self-opening or self-closing) the kind of final position feedback con-
tacts (PFCs) and, if time monitoring is activated, the reference values of breakaway and transit times of the
valves are taught in automatically by an initialisation run. Commissioning can also be done independently
from the configuration wizard by direct parameterisation.
After this first step the monitoring and diagnosis features mentioned above can be activated optionally in a
second step.
A prerequisite to control up to four valves are four independent function blocks (DO type) and transducer
blocks, which are itemized in the engineering tool and which must be parameterised individually as descri-
bed above.
The valve coupler corresponds to the profile identification type number 111 and communication profile 31
according to Fieldbus Foundation specification.
Figure 4.1shows the internal structure of the valve coupler and also the galvanic separation can be seen
there.

Part No.: 108227, Date of issue 27.03.2006
4.2.2 Auxiliary valves which can be connected
The valve coupler FD0-VC-Ex4.FF has been designed particularly for intrinsically safe low power auxiliary
valves in 6 V design, which control the supply of compressed air to the drive.
The following circuit values are applicable (per channel):
US= 6.4 V ... 7.9 V
IS= 1.5 mA (inrush current of the valve)
IHold = 1.0 mA (holding current with the valve switched on)
To switch on, the auxiliary valve is triggered with an increase inrush current ISfor a short period of time.
Then it is held in its position at the lower holding current Ihold.
4.2.3 Final position feedback contacts which can be connected
Two final position feedback contacts per valve can beused for detecting the valve positions. These may be
NAMUR proximity sensors or mechanical switches. The binary signals of both PFCs are requested alterna-
tely from the valve trigger equipment in the 2:1 procedure via a pair of cores and must thus be suitable for
this procedure or be provided with a polarised diode (see section 4.2.4).
4.2.4 Description of 2:1 procedure
The 2:1 procedure allows to transfer two independent binary signals to a pair of cores without bus system.
To do so, the two sensors or mechanical contacts are triggered and evaluated in time multiplex mode anti-
parallel (see figure 4.2).
A prerequisite of this procedure is that the sensors/mechanical contacts are provided with a polarised diode
and one of the two sensors/mechanical contacts is operated in polarised mode. When using NAMUR sen-
sors from Pepperl+Fuchs as PFCs these polarised diodes are integrated. The connection is described in
section 5.4.3.
Do not connect any additional current consumers to the valve circuit (e. g. LEDs).
If additional consumers are connected to the valve circuit, successful operation of
the valve coupler cannot be ensured.
The valve control outputs of the valve coupler can also be checked for correct functioning with-
out connected valves by simulating the valve by a 3 kΩ resistor. In deactivated state, via this
resistor a voltage of approx. 0.3 V and in activated state a voltage of approx. 3 V can be
measured. It is not possible to connect a voltmeter direct to the open terminals of the valve
output because then a voltage USof 6.8 V... 7.4 V is measured independently of the state.
Suitable valves are offered, among others, by Samson, ASCO /Joucomatic and Herion. For
information of suitable valve types please refer to the data sheet and Internet and to
Pepperl+Fuchs.

5 Installation
5.1 Storage and transportation
For storage and transportation the valve coupler should be packed protected from impacts and dampness.
Optimum protection is afforded by the original packaging.
In addition, the permissible ambient conditions must prevail (see datasheet).
5.2 Unpacking
Make sure that the valve coupler is undamaged. Damages should be reported to the mail or forwarding
agent as well as the supplier.
The consignment should be in compliance with the order and shipment documents. Check the following
items:
• Quantity supplied
• Device type and version in accordance with the type plate
• Accessories (manual, etc.)
Keep the original packing if the device must be stored and shipped at a later date.
5.3 Mounting
The housing of the valve coupler with protection degree IP65 is provided for wall mounting. For mounting
use two screws (max. thread diameter 6 mm) for the through bores in the housing (see figure 5.1).
The place of installation should be well accessible for
• mounting
• electrical installation and cable routing
• the six device LEDs should be visible for quick fault diagnosis
• setting of simulation and hardware write protection switches.
The r.h. through bore for mounting the device is provided with a grounding plate at the side of
the screw head so that the device can be grounded directly via the fixing screw when selecting a
suitable place of installation.
When grounding the device via the fixing screw, ensure low-resistance connection with ground.
Otherwise ground via a separate grounding cable.
The mounting set F-TMC is available as accessory for pipe installation (see section 4.3).
In narrow spaces it may be convenient to make the electrical connections prior to the mounting
of the device, also because the PG9 cable glands for the valve connection are arranged very
close to each other and there may be insufficient space for using an open-end wrench.
An SW 19 socket wrench is available as installation accessory for the valve coupler to facilitate
screwing/unscrewing of the PG9 cable glands (see section 4.3).
To keep the protection degree IP65 of the housing, make sure when doing connection work that
unused cable glands are provided with the supplied blank inserts and that these cable glands
are tightened to seal.

Figure 5.2: Valve coupler with the terminal space covers removed
Work at live installations and electrical connections must be carried out by appropriately trained
specialists only.
If the valve coupler is connected with an activated live bus segment make sure that the bus
cables are not short-circuited so that the function of other bus stations is not affected.
To keep the protection degree IP65 of the housing make sure when doing connection work that
• for the connection round cables only are used with the diameter of 4 mm ... 8 mm
for the valves and 5 mm ... 10 mm for fieldbus,
• the cable glands are tightened properly,
• the sealings of the terminal space cover are not damaged and the screws of the ter-
minal space cover are tightened properly,
• and that unused cable glands must be closed by the supplied blank inserts and that
these cable glands are tightened in a sealing way.
