10 Care for and maintain the ED12 pressure
regulator
Servicing the ED12 pressure regulator
No special care is required for the ED12 pressure regulator.
Damage to components!
Solvents and aggressive detergents will destroy the surface, labeling and seals
of the device!
O Only clean the device using a slightly damp cloth. Only use water to do this
and, if necessary, a mild detergent.
Danger of burns caused by hot coils!
Touching the valve coils during operating may lead to burns.
O Let the device cool off before disassembling.
O Do not touch the device during operation.
O Check that all seals and plugs for the plug connections are firmly fitted so that no
humidity can penetrate the ED12 pressure regulator during cleaning.
Maintaining the ED12 pressure regulator
The ED12 pressure regulator is maintenance-free.
O However, the system-specific maintenance intervals must be observed.
Check the ED12 pressure regulator seals
The seals in the ED12 pressure regulator may age faster under aggressive ambient
conditions. Defective seals will lead to pneumatic leaks and non-compliance with the
IP65 protection class.
O Every now and then, check that the seals on the pressure regulator are in perfect
order.

11 If Malfunctions Occur

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 Consumers that use a lot
than the set point of air (>2600 h l/min) cause
a major drop of pressure
in the device.
Outlet pressure does Housing ventilation port
not correspond to the is closed
stipulated set point
Defective diaphragm in the
housing ventilation port
Air is audibly Base plate seal is missing
escaping or damaged
The ED12 pressure
regulator and base plate
are not sealed tight
ED12 pressure regulator
is not leak-tight
Replace pneumatic
connections on the base
plate
ED12 pressure regu- End plate exhaust is closed Open the exhaust and
lator does not bleed
NOTICE
CAUTION
Remedy
Connect the power supply.
Check the polarity of the
power supply.
Switch on system
component.
Stipulate a set point.
Connect the supply
pressure.
Increase the supply
pressure.
Reduce air consumption
Make sure that the housing
ventilation port is open
Exchange the ED12
pressure regulator
Check base plate gasket and
replace if necessary
Tighten screws with 6 Nm
torque
Exchange the ED12
pressure regulator
Correctly replace pneumatic
connections on the base
plate (see "Attach base plate
pneumatic connections")
connect a silencer or a line
for restricted exhaust.
