10 Disassembly and Exchange

Disassembling the ED02 pressure regulator
Danger of burns caused by hot proportional solenoids!
Touching the proportional solenoids during operating may lead to burns.
O Observe the warning sign on the right located on the device.
O Let the device cool off before disassembling it.
O Do not touch the device during operation.
Disconnecting plugs when under voltage will damage the device!
Large differences in potential occur when disconnecting plugs under voltage,
which could damage the device.
O Make sure the relevant system component is not under voltage before
disassembling the device.
The following switch-off sequence must be observed in order to disassemble the
ED02 pressure regulator.
1. Stipulate a set point of 0 bar to exhaust the ED02 pressure regulator and the
outlet line at the outlet pressure connection 2 (2).
2. Switch off the 24 V DC supply voltage.
3. Remove the connected plugs.
4. Switch off the supply pressure and exhaust the supply line.
5. Remove the pneumatic lines.
6. Depending on the type of mounting, remove the mounting screws or loosen the
rail mounting.
If several devices are stacked:
7. Take the screws out of the through holes and remove the desired device.
Exchange the ED02 pressure regulator
To exchange the ED02 pressure regulator, you must first disassemble
it as described above and then assemble a new ED02 pressure regulator
(see "7 Assembly").
11 Disposal
Careless disposal of the ED02 pressure regulator could lead to pollution
of the environment.
O Dispose of the ED02 pressure regulator in accordance with the currently
applicable regulations in your country.

12 Care and Maintenance

Dangerous movements!
Danger of death, injuries or damage to property!
O Always make sure that the relevant system part is not under voltage or
pressure before you clean or service the device. Protect the system against
being switched on.
Danger of burns caused by hot proportional solenoids!
Touching the proportional solenoids during operating may lead to burns.
O Observe the warning sign on the right located on the device.
O Let the device cool down before cleaning or servicing it.
O Do not touch the device during operation.
Servicing the ED02 pressure regulator
No special care is required for the ED02 pressure regulator. Note the following if you
would like to clean the device:
CAUTION
NOTICE
WARNING
CAUTION
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 ED02 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 ED02 pressure regulator
In normal ambient conditions
In normal operation, the ED02 pressure regulator is maintenance-free.
O However, the system-specific maintenance intervals must be observed.
In aggressive ambient conditions
The seals in the ED02 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 IP65
protection class.
O Immediately exchange the device if the seals are defective.

Remedy
Connect the power supply.
Check the polarity of the

Switch on system component.
Stipulate a set point.
Connect the supply pressure.
Reduce air consumption
Use a device with a larger
nominal width (e.g. ED05)
Ensure that the housing

With direct assembly: Check
the pressure line connections
and tighten, if necessary.
With stacking: Tighten screws
