1. Overview of components
1.1
The valve terminal MPA−L
Festo supports your automation tasks at machine level with
the valve terminal MPA−L. The modular structure of the valve
terminal MPA−L enables you to match this valve terminal opti
mally to your machine or system.
The valve terminal MPA−L provides the following connections:
Common ducts for supply and exhaust air
Electric signals from all solenoid coils
Working lines (2) and (4) are provided for each valve position
on the individual pneumatic sub−bases. The valves are sup
plied with compressed air (operating pressure and pilot pres
sure) via the common channels and connections in the basic
components. The exhaust air (from the valves and the pilot
exhaust air) is also exhausted via these common channels.
Further components for compressed air supply are also avail
able, e.g. in order to supply pressure zones.
The valve terminal MPA−L is equipped with current reduction.
The nominal current of the solenoid coils is then reduced
after the high−current phase (switching procedure). The cur
rent reduction offers the following advantages:
Festo P.BE−MPAL−EN en 1008NH
The valve terminal MPA−L has a lower power consumption
The power unit for the voltage supply to the valve ter
minal MPA−L can be designed more economically depend
ing on the individual case
The solenoid coils have less leakage power and produce
less waste heat

The pneumatic supply plate can also be used for additional
power supplies. These are, forexample, necessary in the case
of valve terminals operated with several pressure zones or
when a large number of valves on the valve terminal are
switched simultaneously to flow.
1.5.3
Pilot air supply
The pilot control of the solenoid coils is supplied with internal
or external pilot air. This pilot air is made available for the
complete valve terminal (also via the pressure zones) via the
right−hand end plate (see Tab.1/4).
A selector plate on the right−hand end plate makes it possible
to branch the pilot air internally from the supply port (1) or to
take it from the separate supply via the port (12/14).
Note
Internal pilot air supply is only permitted if the operating
pressure of the last pressure zone (at the right−hand end
plate)isbetween3and8 bar .

1.5.4
Exhaust air
The exhaust (3) and (5) of the air is exhausted together via
the flat plate silencer and the exhaust plate or separately via
the right−hand end plate with ports at the side.
The pilot exhaust air (82/84) is led to a connection on the
right−hand end plate and can either be ducted there or ex
hausted via a silencer.
1.5.5
Sub−bases and pressure zone separation
The valves of valve terminal MPA−L are supplied pneumati
cally via the sub−bases and via the electronic module that is
installed in the sub−base (see Fig.1/4).
In addition to the individual sub−bases there are also the 4 off
sub−bases with common 4 off electronic module.

In addition valves within a valve terminal MPA−L can be sup
plied with different pressures by creating different pressure
zones. The separation of the pressure zones is achieved by
special sub−bases. In each case the valve mounted to the
right of the special sub−base belongs to the next (following on
to the right) pressure zone, which is the valve mounted on the
special sub−base in the current pressure zone.
The sub−bases with integrated pressure zone separation
are in various versions with corresponding identification

Pressure regulating plates
Mode of operation
A pressure regulator plate with adjustable pressure regulator
can be installed between the sub−base and the valve in order
to control the force of the connected actuators. This pressure
regulator maintains an essentially constant output pressure
(secondary side) independent of supply pressure (primary
side) and air consumption.
Identification
The pressure regulator plates of the vertical stacking are
marked on the valve terminal MPA−L with the Ident. code.
This is marked on the side of the pressure regulator plate.

P pressure regulating valve(identification PF, PA)
Supply process
The P pressure regulating valve regulates the pressure in
front of the valve in duct (1)/(P). This provides the same
regulated air pressure in channels (2) and (4).
Exhaust procedure
The exhaust flow is from channel (2) to channel (3) and from
channel (4) to channel (5) through the pressure regulator
plate to the valve terminal.
The advantages of this pressure regulating valve are:
Festo P.BE−MPAL−EN en 1008NH
The pressure regulating valve is not affected by exhausting,
since the pressure is regulated upstream of the valve.
The pressure regulating valve can always be adjusted
because the pressure from the valve terminal is always
present.
1−17
1. Overview of components
Application examples:
An equal air pressure is required at working lines (2)
and (4).
A lower air pressure (e.g.3bar) than the operating pres sure present on the valve terminal (e.g.8bar) is required.
A or B pressure regulator (identifier PH, PG, PC, PB)
Supply process
The work or operating pressure regulator regulates the
relevant pressure of the air (see 1 in Tab.1/9) when the
pressure medium has flowed through the valve. The exhaust
air is passed through the pressure regulator plate and is
switched to the relevant exhaust duct in the valve (see 2
in Tab.1/9).
Exhaust procedure
During exhausting the air is passed unregulated through the
valve and the pressure regulator plate to the valve terminal
(see 3 in Tab.1/9).

The pressure of the air in channel (2) can only be set and
read on the pressure gauge when the valve is in the
switch position: Flow from (1) to (2).
Application examples:
If different air pressures are required at ports (2) and (4)
instead of the operating pressure of the valve terminal.
Fig.1/5 shows the following switching position of the operat ing pressure regulator:
The air is passed from channel (1) through the pressure regu
lator plate and the valve to the operating pressure regulator,
where it is regulated and then passed to connection (2) of
the sub−base. The unregulated exhaust air is then fed via
channel (4) through the pressure regulator plate and then to
channel (5) and vented.

1.7.2
Manual override (MO)
The manual override (MO) enables the valve to be actuated
when not electrically activated or energised. You only need
to switch on the compressed air supply. You should use the
manual override especially when commissioning the pneu
matic system, in order to check the function and operation
of the valve or the valve−actuator combination.
Non−detenting actuation
The valve is activated by pushing the manual override.
On release of the manual override the spring−loaded
valve switches automatically from the switch position to
the normally open position.
Detenting actuation
By turning the manual override clockwise the switch position
can be detented. It remains actuated until it is reset by hand.
These basic functions of the manual override can be changed
by installing a corresponding manual override cover cap:
With a cover for manual override, code: N, locking is pre
vented. The manual override can then only be operated by
non−detenting.
With a cover for manual override, code: V, the manual over
ride can be safeguarded against undesired operation
The operation of the manual override is described in
Chapter4.2.

2.2
Installation/removal on an H−rails
The valve terminal MPA−L is suitable for fitting onto an H−rail
(support rail as per EN 60715). There is a guide groove on the
back for hanging the valve terminal onto the H−rail.
Caution
H−rails with mounted valve terminals can break if they are
subjected to vibration exceeding severity level 1:
0.15 mmAmplitudeat15...58 Hz
2 gaccelerationat58...150 Hz
This can damage the valve terminal, your machine or your
system.
· In this case use wall mounting.
· Note the permitted values for vibration and shock
(see Tab. A/2inAppendix A).
Caution
H−rail mounting without an H−rail clamping unit is not per
mitted.
· Secure the valve terminal MPA−L using the H−rail clamping:
against sliding down with the retaining screw intended for
this purpose (see Tab.2/1 and Fig.2/1)
against unintentional loosening/opening.
In order to mount the valve terminal onto an H−rail you will
require the following mounting kits:

3.1
Compressed air preparation
Caution
Unfiltered or incorrectly lubricated compressed air will
reduce the service life of the valve terminal.
3.1.1 Operation with unlubricated compressed air
Caution
Too much residual oil content in the compressed air will
reduce the service life of the valve terminal.
If bio−oils are used (oils with synthetic ester or true ester
basis, e.g. rape or methylester), the residual oil content
must not exceed 0.1mg/m3 (see ISO8573−1 class2).
When using mineral oils (e.g. HLP oils to DIN 51524,
parts1 to 3) or similar oils based on poly−alpha−
olefins (PAO), the maximum residual oil content of
5mg/m3 must not be exceeded (see ISO8573−1 Class4).
This avoids operative malfunction of the valves.
Excessive residual oil is not permissible irrespective of the
compressor oil, as otherwise the basic lubrication will be
washed out with time.
3.1.2 Operation with lubricated compressed air
Operate system equipment with unlubricated compressed air,
if possible. This is better for the environment. Festo pneu
matic valves and actuators have been designed so that, if
used as intended, they will not require additional lubrication
and will still achieve a long service life.
Festo P.BE−MPAL−EN en 1008NH
3−3
3. Installation
Caution
Operation with lubricated compressed air will cause the
life−time lubrication, which is necessary for unlubricated
operation, to be washed out".
Note the following instructions if lubricated compressed air
must be used:
The compressed air prepared with the compressor must
correspond in quality to unlubricated compressed air. If
possible, do not operate all of your equipment with lubricated
compressed air. If possible, always install the lubricators
directly upstream of the consuming actuators.
Caution
Unsuitable additional oil and an excessive oil content in
the compressed air reduce the service life of the valve ter
minal.
Use Festo special oil OFSW−32 or the alternatives listed
in the Festo catalogue (as specified in DIN51524−HLP32;
basic oil viscosity 32CST at40 °C).
Theadditionallubricationmustnotexceed25 mg/m
(ISO8573−1 class 5).
3
Make sure that the lubricator setting is correct
(see following section)
This avoids operative malfunction of the valves.
Setting the lubricator:
With the machine running (typical operating status) 0.2 to
max. 1 drops/min. or 0.5 to 5 drops/1000l of air .
Checking the setting:
The procedure described below can be used for checking the
setting of the lubricator.
Proceed as follows, in order to check the service units with
respect to condensate and lubricator settings two times per
week.
3−4
Festo P.BE−MPAL−EN en 1008NH
3. Installation
1. Ascertain the actuator which is furthest from the lubricator.
2. Ascertain the valve terminal which controls this cylinder.
3. Remove the silencer, if fitted, from port (3/5).
4. Hold a piece of white cardboard 10cm in front of the
exhaust port.
5. Let the system run for a short period.
There must be only a slight yellow colouring on the card
board.
If oil droplets appear, this is an indication that too much oil
has been used. Another indicator is the coloration or the
condition of the exhaust air silencer. Distinctly yellow colour
ing of the filter element or drops of oil on the silencer indicate
that the lubricator setting is too high.

General instructions on installation
Warning
Uncontrolled movements of the connected actuators and
loose tubing can cause injury to persons and/or damage
to property.
Before carrying out mounting, installation and mainten
ance work, switch off the following:
Compressed air supply
The operating and load voltage supplies.
Pay attention to the following:
The components of the valve terminal contain electrostatically
sensitive components. The components will be damaged
if you touch the contact surfaces of the plug connectors or
if you do not observe the handling specifications for electro−
statically sensitive devices.
Note
Handle all modules and components of the valve terminal
MPA−L with great care.
Note especially the following:
Screws must be fitted accurately (in particular to avoid
damage to threads on plastic housing parts) and
screwed in by hand
The specified torques must be observed
Clean connecting services (avoidance of leaking and
contact faults) and intact seals and sealing surfaces
Close unused connections with blanking plugs to avoid
contamination and maintain reliability.
back pressure
3−6
When exhausting large volume actuators or if the exhaust
performance is too small, back pressures can build up in the
valve terminal exhaust ducts. The back pressures can lead to
pneumatic actuation of other valves, especially with un
switched 3/2−way valves that are normally closed.
Festo P.BE−MPAL−EN en 1008NH
3. Installation
To avoid back pressures:
3.3
·
Optimise the ventilation and exhaust performance of
the valve terminal e.g. by using lar ger pipe diameters or
additional compressed air supply via pneumatic supply
plates with exhaust via silencers and exhaust plate.
·
Separate exhaust ducts by using pressure zones if
necessary(seeChapter 1.5.3).
Connecting the valve terminal MPA−L
Connections on the following components are available for
supplying the valve terminal:
3.3.1
To the pneumatic supply plate, type VMPAL−SP
To the right−hand end plate, type VMPAL−EPR−SP
Pilot control of the solenoid coils (pilot air supply)
Internal pilot air supply
Iftheoperatingpressureliesbetween3...8 bar
, you can
operate the pilot control of the solenoid coils with an inter
nally branched pilot air supply.
Note
· Internal pilot air supply is branched centrally from sup
ply connection(1) for all solenoid coils. When operating
the valve terminal with several pressure zones the inter
nal pilot air supply is taken from the pressure zone,
which is directly adjacent to the right−hand end plate
(see Fig.3/1 and Fig.3/2).
Festo P.BE−MPAL−EN en 1008NH
3−7
3. Installation
External pilot air supply
If the operating pressure lies below 3bar or abo ve8 bar,
pilot control of the solenoid coils must be operated with
an external pilot air supply.
Note
· Use preferably closed−loop regulated external pilot air.
Reliable faultless operation of the valve terminal is then
possible, e.g. even with fluctuating operating pressure.
· The external pilot air supply is supplied centrally for all
solenoid coils via pilot connections(12/14) on the right−
hand end plate. This also applies when the valve ter
minal is operated with two pressure zones.
· For external pilot air supply the pilot air pressure must
be adapted to the operating pressure, but only within
the valuesof3...8bar .
The conversion between the internal and external pilot air
supplyisdescribedinChapter 5.3.6.
3.3.2
Valve terminal MPA−L with pressure zone separation
The pressure zones are separated from each other by special
sub−bases(seeChapter 1.5.5). Each pressure zone must be
supplied by pneumatic supply plate and via a right−hand end
plate with side connections with compressed air. The position
of the supply plate within the pressure zone (left, centre or
right) is arbitrary.
By fitting a second supply plate within a pressure zone you
can provide additional supply air and exhaust air to optimise
the ventilation and exhaust performance of the valve ter
minal.
For each additional pressure zone a special sub−base is re
quired for separation and a special pneumatic supply plate is
required for supply (see Fig.3/1 and Fig.3/2).

For controlling the valves, each solenoid coil is assigned to a
certain pin of the multi−pin plug socket (see Tab.3/6).
Note
Use a uniform method of control within a multi−pin plug:
Preferably, all control signals should be positive switching
(0 −> 1/off −> on), otherwise all control signals negative−
switching (1 −> 0/on −> off ).
Mixed mode control is not permitted!

Configuration of the address space
From the point of view of the CPX terminal the pneumatic
interface is seen as an electrical module with a variable
(configurable via the rotary switch) number of digital outputs
for the control of the attached valves
For a valve terminal MPA−L with CPX terminal a maximum of
32solenoid coils are controllable, independently of the posi tion of the rotary switch (see Tab.3/8).
Note
On conversion or expansion of the valve terminal MPA−L
the number of output addresses assigned by the pneu
matic system via the rotary switch on the pneumatic inter
face must be checked and adapted if necessary.
This is not necessary if previously a sufficiently large ad
dress space for the expansion has been reserved.

Adjustment rules for the size of the address space
If the number of solenoid coils fitted is less than the

the superfluous addresses will be reserved for later ex
tensions (if the maximum number of valves is fitted, out
put addresses will then remain unused).
Modifications to the configuration will not become effec
tive until the operating voltage is switched on again.

General Information
Prior to commissioning
·
Switch off the power supply before connecting or discon
necting plug connectors (otherwise functional damage).
·
Only commission a valve terminal that has been mounted
and wired completely.
·
Make sure that there is a sufficient supply of fresh air
(cooling) for the following operating conditions:
When the maximum number of valves are fitted
When the maximum operating voltage is applied
When the solenoid coils are constantly under stress
·
Note the specifications concerning the medium.
Pressure build−up in the overall supply
Warning
If the pressure build−up of the pilot air supply is too slow
or delayed, this may cause the actuators to perform
sudden unexpected movements under the following condi
tions:
When the compressed air is connected via a soft−start
valve (gradual pressure build−up) and
If there are electric signals (e.g. after EMERGENCY STOP)
This can cause damage to the machine or system and even
injury to persons.
· Operate the valve terminal with an external pilot air
supply (3 ... 8 bar). Branch the pilot air supply before
the soft−start valve (see Fig.4/1).
Festo P.BE−MPAL−EN en 1008NH
4−3
4. Commissioning
The pilot air supply must reach a pressure of 3 ... 8 bar.
Otherwise it is not ensured that the valve will switch directly
(see Fig.4/1).
If the pressure is less than 3 bar, there may be a delay before
the valve is switched, in spite of an electric signal being pres
ent. The gradual pressure build−up of the overall supply does
not affect the actuator in that case. The actuator would react
suddenly (e.g. a cylinder would extend or retract suddenly ,
depending on the valve function).

Warning
Before actuating the manual overrides:
Uncontrolled actuation of solenoid coils can cause the
actuators to perform sudden unexpected movements
which may cause personal injury and material damage.
· Disconnect the power supply for the solenoid coils at
the relevant connections on the valve terminal MPA−L.
This prevents accidental actuation of the solenoid coils.
Before switching on the power supply:
During commissioning, manual overrides that are in the
switched state can cause actuators to perform sudden
unexpected movements. These movements can cause
injury to persons and damage to property.
· Make sure that all manual overrides are reset to their
initial position.
You will thereby avoid undefined switching states of the
valves.
Warning
Before testing the valve/actuator combination:
Make sure that nobody is in the danger zone.
Note
A valve that has been switched by an electric signal cannot
be reset by the manual override. The electric signal is
dominant in this case.
· Reset the electric signal before actuating the manual
override.
Proceed as follows:
1. Switch on the compressed air supply.

4. Commissioning
2. Check the functioning and operation of each individual
valve/actuator combination by actuating the manual over
ride as shown in the following diagrams.
Note
Incorrect actuation of the non−detenting manual override
can lead to malfunctioning or damage to the manual over
ride.
· Use a screwdriver (blade width max.3mm) to actuate
the manual override.
· Operate the manual overridetomax.25 N.
3. With a detenting manual override: After testing the valves,
make sure that all manual overrides are in their initial
positions again.
Caution
Valves with manual overrides in switch position can move
actuators unintentionally during commissioning. This can
cause injury to people and damage to property.
· Prior to commissioning, reset all manual overrides to
their initial positions again.
If the manual override is in the actuated state, it is not
possible to reset the valve to its neutral position with an
electric signal. The manual override is dominant in this
case.

Conversion of the MPA−L valve terminal
You can convert the valve terminal MPA−L at a later date and
adapt it to requirements by adding valve positions. The fol
lowing conversion work can be undertaken on the valve ter
minal MPA−L:
Shortening the
valve terminal
Conversion between ducted and unducted exhaust air
Conversion between internal or external pilot air supply
Conversion to different pressure zones
Adding valve positions (sub−bases)
Adding supply plates for additional pneumatic power
supply
The shortening of the valve terminal MPA−L by a few valve
positions is only possible if the tie rod system is created from
individual expansion pieces (see Tab.5/1).
Information on permitted possibilities of combining MPA−L
components and accessories can be found in the Festo Cata
logue (see www.festo.com\catalogue).
5.3.1
Tie rod system
The mechanical connection between the modules of the valve
terminal MPA−L is achieved via a tie rod system in the sub−
bases between the two end plates.
This tie rod system is used for valve terminal MPA−Ls that
consist of at least four VMPA1 sub−bases and supply via right−
hand end plates with lateral ports or two VMPA1 sub−bases
and a supply plate.

ID code: I, Function: 1)
Two monostable 2/2−way valves,
both valves normally closed, valve on control
side 14 reversible
Pneumatic spring return
With dual−pressure operation:
Supply operating pressure via connection 1
Operating pressure can be separately
supplied at connection (3/5).
Solenoid coil 14 switches the operating
pressure from connection (5) to
connection (4)
Solenoid coil 12 switches the operating
pressure from connection (1) to
connection (2)
With vacuum operation:
Feed operating pressure via connection (1)
Feed vacuum via connection (5)
Solenoid coil 14 switches the vacuum to
connection (4)
At connection 4 or in tubing (4) a filter is
provided, so that no dirt can enter the
valve.
Solenoid coil 12 switches the operating
pressure to connection (2) (e.g. for an
ejector pulse in vacuum operation)
Establish a connection using a T−piece for
an ejector pulse between connections (2),(4)
and the vacuum generator
1) Note: If this 2/2−way valve (Ident. code I) is also operated with other valves on the MPA−L valve
terminal, then this 2/2−way valve must be operated in a separate pressure zone with a
separate exhaust air channel (5).
