Safety Instructions
Appropriate Use
The change-over valve is exclusively designed for use in
centralized lubrication systems.
Do not exceed the maximum ratings mentioned in the
Technical Data, particularly the maximum operating
pressure.
Any other use will not be conform.
The manuafacturer is not responsible for damage resulting
from incorrect use.
Maintenance and Repairs
Before executing maintenance and repair work at the
change-over valve read the Owner s Manual and the
Safety Instructions.
The Owner s Manual must be available at the place where
the unit is in operation.
Alterations or modifications of the change-over valve are
only allowed if approved by the manufacturer.
Use only original spare parts for repair work.
If other parts are used, the manufacturer may be released
from his liability for the resulting damage.
Operation of the Change-over va ve
The change-over valve should be used only if it is in a good
state.
Defects which impair the function and the safety must be
remedied to immediately.
The function of the change-over valve is only guaranteed if
clean hydraulic oil and lubricant are used.
If you require more information than mentioned in this
Owner s Manual, Please contact us (see address at the
bottom of the page).
Structure and Mode of Operation
The change-over valve operates like a hydraulically operated
4/2-way valve which alternately discharges the lubricant fed
by the pump into one of both main lines, while the other main
line is connected to the return line connection of the pump.

Erection and Assembly
Requirements on the insta ation site:
even, solid and vibration-free installation site
protected from dust and dirt
safe from atmospheric influences
position of installation: any
E ectric connection
Before connecting the unit, disconnect
the system from the power supply.
The assembly and installation of electri-
cal devices should be carried out only by
an electrician!
Observe the relevant rules of engineering
and the respective safety provisions
(rules, standards).
Perform the electrical connection of the
solenoid in accordance with the
connection diagram.
CAUTION
Operating Instructions
Putting into operation
After connection of the tube lines and the electric lines, the
change-over valve is ready for operation.
Maintenance and repairs
Repair work should be carried out only by qualified person-
nel using original replacement parts. Provided that only
clean lubricant is used, the change-over valve does not
need any particular maintenance.
The reversing piston is subject to natural wear which de-
pends on the operating time and the adjusted operating
pressure. For repairs, the complete reversing block must
be replaced because the piston is fit to precise tolerances
in the factory.
Before carrying out e ectrica repair
work at the change-over va ve,
p ease observe the fo owing:
* Disconnect the system from the
power supply and take the necessary
measures to avoid it being switched
on again by accident.
* Reduce the system pressure to zero
* Risk of lubricant splashing off

Subject to change witout notice
In case of defects, first check whether the pump operates with full pressure.
Fau t: No changing-over is initiated
Cause Remedy
Solenoid valve defective Replace solenoid valve
No air pressure available or air presssure too low Check the air pressure supply
No voltage supply or voltage supply too low Check the voltage supply and the coil
End-of-line pressure switch does not transmit signal Check function, adjustment and electric cable of end-
of-line pressure switch
Fau t: no pressure bui d-up or pressure bui d-up too s ow
Cause Remedy
Leakage in the line system Check the main lines and the two-line metering
or in the two-line metering devices devices
Piston in reversing housing worn Replace the complete reversing housing
