1) The product is basically designed for the use of harmless media. The operator must check whether the lubricant used has certain
hazardous effects (e.g. sensitization). If necessary, a retention tray may be required.
2) The integrator has to ensure that the pump is integrated into the machine in such way that operation and filling of the pump are
ergonomically possible.
3) The acoustical level is varying and depends on many factors such as eg micropump number, the working frequency and environment.
Therefore personal protective equipment against noise must be provided to operators.
4) The operator must adjust the carrier air pressure for oil projection in order to prevent any oil mist. If the risk cannot be completely
avoided, the integrator must provide the containment of the machine to which the lubrication unit is integrated and an oil mist evacuation
device.
5) The integrator has to ensure that the pump is integrated into the machine in such way to have a quick and safe access to control and
monitoring devices of the lubrication unit.
6) The integrator must provide isolation devices for energy supply (electricity and compressed air) to the lubrication unit.

operator whether the lubricant needs to be replaced due to
ageing processes (bleeding). If there is any doubt as to the
further suitability of the lubricant, it must be replaced before
recommissioning. If you have no experience with the lubricant
used, we recommend testing after only one week.
2.5 Avoidance of malfunctions and
hazards
To avoid malfunctions or hazards, please observe the following:
•When handling lubricants, observe the relevant safety data
sheets (SDS) and hazard designations on the packaging, if
any.
•Due to the large number of additives, individual lubricants
which meet the requirements for pumpability specified in the
instructions may not be suitable for use in centralized
lubrication systems.
•Always use SKF lubrication greases, if possible. These are
optimally suited for use in lubrication systems.
•Do not mix lubricants. This may have unforeseeable effects
on the characteristics and on the usability of the lubricant.
•The ignition temperature of the lubricant must lie at least
50 K over the maximum surface temperature of the
components.

3. Overview, functional
description
3.1 Description
3.1.1 General
The VTEC unit is a modular unit made up of one to eight
different modules. Each module allows lubrication of a
lubrication point using a micropump.
The VTEC unit can jointly or independently control and
monitor the lubrication of several lubrication points. The user
can therefore manage different independent lubrication circuits
with a single unit.
The modular nature of the VTEC unit makes it possible to:
•Lubricate 1 to 8 lubrication points with a single unit
•Individually adjust the flow rate of a micropump
corresponding to a lubrication point
•Adjust the lubrication frequency for a single lubrication point
or multiple lubrication points together
•Adjust the carrier air flow independently for each lubrication
point
•Visually (pressure gauge) or electrically (pressure switch)
monitor the carrier air pressure individually for each
lubrication point
3.1.2 Construction

This is a front side view with the compressed air and oil inlets
on the left side.
The unit has one oil inlet with quick-release connector, and
two compressed air inlets with quick-release connector. But
only one air inlet port is used, the other being closed with a
screw plug. The lower air inlet port is used when the first
module has a “i” base (with a general air solenoid valve). The
upper inlet port is used with every other bases.
Except the “I” base, with the general air solenoid valve, all
other bases work in the same way.
Every module has on the top an outlet port for coaxial hose
air and lubricant with two quick-release connectors. The quick-
release connector for the capillary tube (lubricant) is located
beneath the quick-release connector for the outer tube (air).
The user can set the carrier air pressure with a pressure
regulator. The air flow can be monitored either with a pressure
gauge or with a pressure switch.
A pneumatic micropump is mounted under every module.
The user can adjust the flow rate of the pump with metering
rings or with a thumb wheel.
A module can have up to two different additional equipment
on the front side:
•a pneumatic impulse generator to adjust the delivery
frequency of the micropump
•an air solenoid valve to control the air inlet for the pneumatic
micropump.
Every module can have one or two of the equipment.
According to the equipment a module is “slave” or “master”.

VTEC unit function
(→ fig. 1)
•Unit for two independent lubrication circuits, the first with
three lubrication points, the second also with three points
•Start-up is independent for the two circuits by general air
solenoid valves
•For the first circuit, the operator can manage a pause phase
and a lubrication phase with the control air solenoid valve,
and then manage the beat frequency of the micropumps
during the lubrication phase with the pneumatic frequency
generator.
•For the second circuit, the operator manages the beat
frequency of the micropumps with the control air solenoid
valve (an activation of the solenoid valve corresponds to a
beat of the micropump)
•The operator monitors the general pneumatic pressure of the
first circuit with a pressure switch (set at 5 bar), and of the
second circuit with a pressure gauge
•The operator can monitor the carrier air pressure for each
module
•The flow rate of each micropump goes from 10 to 30
mm3/stroke, with range adjustment by ring

3.2 Function
When the VTEC unit is switched on, it is supplied with
compressed air (5 to 8 bar) and with lubricant (0,1 to 0,5 bar).
The oil flows through the different bases to the volumetric
pneumatic micropump. The delivery frequency of the
micropump (max. 3 stroke/s) is independently adjusted with
either a pneumatic impulse generator or a solenoid valve, which
is controlled via a control unit. The flow rate of the micropump
can be adjusted with metering rings or with a thumb wheel.
The micropump delivers a metered quantity of oil, which goes
through inner channel of the base to the coaxial outlet port.
The compressed air also flows through the different bases
and is divided in two ways in each of them. Some compressed
air is supplied to the micropump to actuate it. The other part of
the compressed air (called carrier air) is supplied to the coaxial
outlet port and goes through the outer tube of the hose. The
carrier air pressure of every base can be adjusted with a
pressure regulator. This pressure can be also monitored by
means of a pressure gauge or a pressure switch.
The low-pressure carrier air and oil are simultaneously
transported under pressure via the coaxial hose to the nozzle.
The carrier air is swirled in the nozzle. As a result, the metered
quantity of oil is broken down into microdroplets, which are
transported by the carrier air to the friction point without
causing any mist. The microdroplet size (200/600 m) ensures
a perfect oil coating without atomization.

5. Delivery, returns, storage
5.1 Delivery
After receipt of the shipment, it must be inspected for any
shipping damage and for completeness according to the
shipping documents. Immediately inform the transport carrier
of any shipping damage. The packaging material must be
preserved until any discrepancies are resolved.
5.2 Return shipment
Before return shipment, all contaminated parts must be
cleaned. If this is not possible or practical, e.g. if it would impede
fault detection in the case of complaints, the medium used must
always be specified. In the case of products contaminated with
hazardous substances as defined by GHS or CLP regulations,
the safety data sheet (SDS) must be sent with the product and
the packaging must be labelled in accordance with GHS/CLP.
There are no restrictions for land, air, or sea transport. The
choice of packaging should be based on the specific product and
the stresses to be expected during transport (e.g., necessary
anti-corrosion measures in the case of shipment by sea). In the
case of wooden packaging, the applicable import regulations
and the IPPC standards must be observed. Required certificates
must be included in the shipping documents. The following
information, as a minimum, must be marked on the packaging
of return shipments.
Fig. 5
Marking of return shipments
5.3 Storage
The following conditions apply to storage:
•Dry, low-dust, vibration-free, in closed rooms
•No corrosive, aggressive substances at the storage location
(e.g., UV rays, ozone)
•Protected against animals (insects, rodents)
•If possible, keep in the original product packaging
•Protected from nearby sources of heat or cold
•In the case of large temperature fluctuations or high humidity,
take appropriate measures (e.g. heating) to prevent the
condensation of water
•Before usage, check products for damage that may have
occurred during storage. This applies in particular to parts
made of plastic (due to embrittlement).
5.4 Storage temperature range
For parts not filled with lubricant, the permitted storage
temperature is the same as the permitted ambient temperature
range (see “Technical data”).
