General notes
Work on the valve should only be carried out by specialist staff and with the correct tools!
Before working on the system, always turn off the supply voltage!
Clean the piping system before installing the valve!
Where necessary, connect a strainer upstream to protect against faults.
When tightening the connections, never use the coil as a lever!
Ensure that the operational conditions agree with the performance data of the unit!
Avoid back-pressures in the exhaust channels by the use of large-volume silencers!
Pressure indicator with indicating pin on the connecting module - right -
(Figure: Technical Description - Example of a block assembly )
- Indicating pin can be pressed in: pressure in valve block < 1 bar
- Indicating pin cannot be pressed in: there is pressure in the valve block
- Indicating pin springs back: there is pressure in the valve block
(vent the system before dismantling
lines or devices)
Setting up block assemblies using the modular pneumatic
rail MP07
With combination of two-way and three-way base modules, you can assemble valve blocks of any size.
Check that each module is completely pre-fitted with O-rings!
Before locking together, lightly grease or oil the fitted O-rings.
Insert the hooks of the module being added into the slot on the previous module, ensuring that the O-
rings are correctly seated!
Press the modules together until both hooks latch.
Ensure that the profile gaskets are correctly seated on the base module!
ATTENTION! Lines or valves must never be loosened while the system is under pressure!
Observe the pressure indicator on the right-hand connecting module.
ATTENTION! Squashed O-rings and profile gaskets sause leackages in the block!
NOTE It is advisable to start the assembly with the left-hand connector module. (Figure:
Technical Descriptions - Example of a block assembly )

INSTALLATION, INITIALISATION AND SERVICE
english
Dismantling the module
Unlatch both locking hooks by using a screwdriver on the end dismantling-grooves.
Remove the block part / module sideways.
Other possible uses of the connecting module, - right-hand -
• As a separation module for special applications when building up several pressure levels in a single
block
• Additional supply lines for larger valve blocks
Secure the valves to the base module using 2 M4 screws each.
(Tightening torque max. 1.5 Nm).
Mount the complete valve block onto the wall or the standard rail.
Connect the supply and working lines.
Make the electrical connections to the pilot valves: in doing this, observe the values given on the rating
plate!
NOTE Where necessary, break out the rated break-points of Ports 1, 3 and 5 and
the upper pilot venting.
Installation
Hang the valve block onto the upper groove of the standard rail.
Latch the lower clamp into the standard rail.
Firmly tighten the screws on the clamp.
Dismounting
Loosen the clamping screws (by about 4 revolutions).
Remove the block upwards from the standard rail.
Mounting the valve block
Standard rails
• Standard rail 35 x 15 DIN 50022 (Standard)
• Standard rail 75 x 25 DIN 50023
NOTE When using the 75 x 25 DIN 50023 standard rail, change over the pre-assembled screws
with clamps and springs as necessary.

Mounting single valves
Fix the single valve directly to the wall using M4 screws. (Figure: Insstallation, Initialisation and Service
- Mounting single valves ,
NOTE For plug-in connections, the hose lines must meet the following requirements:
• Minimum rigidity of 40 Shore D (to DIN 53505 or ISO 868);
• External diameter corresponding to DIN 73378 (max. permissible deviation ± 0.1 mm
from nominal dimension);
• Without burr, cut at right-angles and with undamaged circumference;
• The hose lines must be pushed into the plug-in connectors up to the stop.
Plug-in connections
Dismantling the plug-in connections
To release the line, press in the pressure ring and pull out the hose line.
Manual override
For manual operation of the valve depress the
manual actuator to the stop.The manual
actuator is then locked by turning 90° to the
right.
Indicating pin for indicating the pneumatic
position
With the valve not switched, the red indicating
pin can be pressed in. If the valve has been
switched, the indicating pin moves outwards,
and remains in this position.The indicating pin
must be pushed in again for every functional
test.
Designation plate (can be removed for marking
/ engraving)

• not used in the standard model
• used as an auxiliary pilot air connection
and as the connection for pneumatic

Measures to be taken before putting into service
Check all connections, voltages and the operational pressure!
Ensure that the max. operational conditions (see rating plate) will not be exceeded!
Check that Ports 1, 3 and 5 are correctly connected according to the regulations.These connections
must not be interchanged for any reason!
When operating electrically, unlock the manual override!
Pulse operation
Function:
ATTENTION! Observe the “Pulse” data on the rating plate!
Avoid simultaneous pulse input to both coils!
The pulse-controlled solenoid valves operate with two coils connected alternately.
NOTE The valves can be reversed with the manual actuator.

Faults
Fault Possible cause Correction
Valve does not
switch
Operational voltage too low or
not present;
Check the electrical supply connections.
Ensure that the electrical power supply is the same as
that spe-cified on the rating plate.
Manual override not in neutral
position;
Set the manual override to the zero position.
Compressed air supply not
available or insufficient.
Carry out the dimensioning of the compressed air
connection with volumes as large as possi-ble (including
that of upstream pressure regulators, service units, cut-
off valves etc.)
Minimum operational pressure 2 bar
Valves switch
with a delay, or
exhaust
through the
venting ports:
Compressed air supply not
available or insufficient;
Führen Sie die Druckversorgung möglichst großvolumig
aus (auch bei vorgeschalteten Geräten wie
Druckreglern, Wartungseinheiten, Absperrventilen usw.).
Mindestbetriebsdruck 2 bar
Valves are not in the starting
position (whitout current)
during pressure build-up.)
Appley pressure to the valve block before you switch the
valves
Insufficient venting of the
exhaust channels due to
silencers that are too small or
are soiled (back-pressure);
Use silencers or expansion channels with sufficient
dimensions.
Clean soiled silencers.
Impurities or foreign matter in
the pilot valve or main valve.
Blast through the exhaust cahnnels with pulsed
compressed air, to blow out impurities. Install a new pilot
or main valve if these measures bring no improvement.
Leaking valve
block:
O-rings between the modu-
les missing or damaged;
Check for leaks and for missing seals.
Missing or incorrectly posi-
tioned profile gaskets be-
tween the valve and the
baseplate.
Install the missing seals and replace damaged seals.
