Damage to components
Solvents and aggressive detergents will destroy the surface, labeling and seals of
the device!
O Check that all seals and plugs for the plug connections are firmly fitted so that
no humidity can penetrate the EV07 pressure regulator during cleaning.
O Only clean the device using a slightly damp cloth. Only use water to do this
and, if necessary, a mild detergent.
Maintaining the EV07 pressure regulator
In normal ambient conditions
In normal operation, the EV07 pressure regulator is maintenance-free.
O However, the system-specific maintenance intervals must be observed.
In aggressive ambient conditions
The seals in the EV07 pressure regulator may age faster under aggressive ambient
conditions.
O Every now and then, check that the seals on the pressure regulator are in perfect
order. A damaged seal can be recognized by parts of the seal visibly protruding
from the housing gaps. Defective seals will lead to pneumatic leaks and non-
compliance with the IP54 protection class.
O Immediately exchange the device if the seals are defective.
O Clean the filter for the pilot (9). To do this, loosen the blanking screw on the filter.
13 Troubleshooting
Malfunction Possible cause
No output pressure No power supply
present
No set point stipulated
No supply pressure
available
Outlet pressure too Supply pressure too low
low
Outlet pressure less A load with high air
than the set point consumption results in a
large pressure drop in the
device.
Outlet pressure does Housing ventilation port is
not correspond to the closed
stipulated set point
EV07 pressure Exhaust port silencer is
regulator does not clogged
exhaust
EV07 pressure Pilot exhaust opening is
regulator response to closed
changes in the set
point are slow
Air is audibly escaping Seal at the inlet connection
or outlet connection is
missing or damaged
Leakage between the EV07
pressure regulator and the
connected pressure line
EV07 pressure regulator is
not leaktight
Pneumatic connections
confused
Output pressure jumps Set point too high
to the level of the (> 20 mA or > 10 V)
supply pressure
NOTICE
Remedy
Connect the power supply.
Check the polarity of the
power supply.
Switch on the system
parts.
Stipulate a set point.
Connect the supply
pressure.
Increase the supply
pressure.
Reduce air consumption
Use a device with a larger
nominal width
Ensure that the housing
ventilation port is open
Make sure the exhaust port
is open
Make sure that the exhaust
opening (4) is open
Check the seal and
exchange, if necessary
With direct assembly:
Check the pressure line
connections and tighten, if
necessary
Exchange the EV07
pressure regulator
Connect the pneumatics for
the pressure lines correctly
(see „Connecting the
pneumatics")
Stipulate the correct set
point
