4 Product overview
4.1 Function
The valve terminal VTOP has a modular design and, depending on the modules used, the following
additional pneumatic functions can be implemented:
–Compressed air regulation and filtering
–Volume flow boost
–Reaching a defined end position in the event of a pressure failure
–Safe venting
–Direction reversal for double-acting pneumatic drives
The valve terminal VTOP, the pneumatic drive and the positioner are mechanically and pneumatically
connected by the adapter plate VABA. The compressed air supply is connected centrally to the pneu-
matic ports of the adapter plate VABA. The AiRing function distributes the compressed air internally.
This eliminates the need for complex tubing or piping for the individual modules.

4.3.3 Volume booster VOGM
The VOGM volume booster is used if the process valve’s operating times have to be reduced. The
direct integration of the VOGM volume booster in the control loop means that the pneumatic drive can
be precisely positioned even with fast response times.
The response sensitivity for initialisation is set using a flow control screw for a single-acting module
and two flow control screws for a double-acting module è 9.2 Adjusting volume boost.

the compressed air. The filter can be replaced if contaminated è 10.1 Changing the filter. A pressure
gauge can be mounted to display the set outlet pressure è 6.3.1 Mounting pressure gauge. The set
outlet pressure can be secured against unauthorised adjustment è www.festo.com/catalogue.

4.3.5 Fail-safe module VOGI
The fail-safe module VOGI is used to achieve a defined end position in the event of a compressed air
failure. If the compressed air supply at the pneumatic connection of the adapter plate VABA fails, the
fail-safe module VOGI automatically depressurizes duct 2 and duct 4 is connected via the redundant
pneumatic supply air connection (1) at the fail-safe Module VOGI pressurised with compressed air. The
defined end position depends on the orientation of the reversing plate in the end plate è 4.3.7 End
plate VABE.

Product overview
4.3.6 Flange module for safety functions VABP
The flange module VABP for safety functions serves as an interface for safe venting in an emergency.
The use of control valves makes it possible to implement safety functions (HFT 0, HFT 1) for safe
venting with various safety architectures. Exhaust duct 2 of the mounted control valve is always
directly connected to duct 2 of the pneumatic drive, independently of other modules and module
positions of the valve terminal VTOP.
The flange module for safety functions VABP only provides the interface for various safety architec-
tures and is not a safety device.
The safety-related values are dependent on the specific control valve and the selected safety architec-
ture.

4.3.7 End plate VABE
The end plate VABE is the terminating module of the valve terminal VTOP and must generally be used.
A reversible reversing plate is located inside the end plate VABE. The orientation of the reversing plate
defines the effective direction and, at the same time, the end position if the compressed air supply
fails in the double-acting pneumatic drive.

1. Remove the transport locks.
2. Check that the seals on the modules are seated correctly.
3. Connect the modules correctly.
4. Apply the screws and tighten evenly. Tightening torque: 10 Nm ± 20%
6.2 Attachment
6.2.1 Attaching valve terminal VTOP
The valve terminal VTOP is attached to the pneumatic drive via the adapter plate VABA.
• Mount the adapter plate VABA to the pneumatic drive
è Assembly instructions for adapter plate VABA.
The linear drive DFPI -...- E-NB3VM12 is delivered with the adapter plate VABA mounted on the
pneumatic drive at the factory.

1. Select suitable adapters è www.festo.com/catalogue.
2. Attach the positioner to the adapter plate VABA
è Assembly instructions for adapter and positioner.
6.3 Mounting accessories
6.3.1 Mounting pressure gauge
A pressure gauge can be mounted to display the set outlet pressure at the filter regulator PCRI.
1. Select the appropriate pressure gauge è www.festo.com/catalogue.
2. Unscrew the plug screw at the pressure gauge connection.
3. Check that the seal on the pressure gauge is seated correctly.
4. Screw in the pressure gauge to the stop. To align, turn the pressure gauge back a maximum of one
turn.
6.3.2 Removing pressure gauge
1. Unscrew the pressure gauge from the pressure gauge port.
2. Screw in the plug screw with seal on the pressure gauge connection up to the stop.
6.3.3 Mounting control valve
Functional safety functions for safe venting can be implemented with various safety architectures by
mounting control valves at the corresponding interfaces on the flange module for safety functions
VABP.
The achievable hardware fault tolerance (HFT) depends on the flange module and the number of
control valves:
–HFT 0: Module VABP-C13-100HFT0 -... with 1 control valve
–HFT 1: Module VABP-C13-100HFT1 -... with 2 control valves

The position of the control valve can be freely selected. A covering is mounted on the upper interface
of the control valve at the factory. If an interface with mounted covering is used, the covering must be
offset.
