Safety Instructions
Appropriate Use
• The product is exclusively designed for the use in centrali-
zed 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 manufacturer is not responsible for damage resulting
from incorrect use.
Maintenance and Repairs
• Before executing maintenance and repair work on the
product read the Owner Manual and the Safety Instruc-
tions.
• The Owner Manual must be available at the place where
the unit is in operation.
• Alterations or modifications of the product 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 valve and the way valve
• The product should be used only if it is in a good state.
• Defects which impair the function and the safety must be
remedied 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 Manual, please contact us (see address on 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 installation site:
• even, solid and vibration-free installation site
• protected from dust and dirt
• safe from atmospheric influences
• position of installation: any
Electric 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
The supply voltage and the voltage
of the solenoid valve must agree.
Operating Instructions
Putting into operation
• After connection of the tube lines and the elecric 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 product does not need any
particular maintenance.
The reversing piston is subject to natural wear which
depends on the operating time and the operating pressure
adjusted. For repairs, the complete reversing block must
be replaced because the piston is fit to precise tolerances
in the factory.
Before carrying out electrical repair
work on the product, please observe
the following:
* 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

In case of defects, first check whether the pump operates with full pressure.
•Fault: No changing-over process is initiated
•Cause •Remedy
• Solenoid valve defective • Replace solenoid valve
• No air pressure available or air pressure 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 any signal • Check function, adjustment and electric cable
(for change-over valve MP2) of end-of-line pressure switch
•Fault: no pressure build-up or pressure build-up too slow
•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
