1 PRODUCT DESIGNATION
This document serves as a guide for proper handling, storage, installation, commissioning, operation
and maintenance of the product:
SAO/SAG lubrication unit
This is a standard product. Individual products are identified by a production label, which shows the
code designation, year of manufacture and serial number.
2 APPLICATION
SAO lubrication units, version for lubricating oils, and SAG, version for soft greases, are used
exclusively as pressure lubricant sources for single-pipe central lubrication circuits, which are
equipped with single-pipe metering valves series SKIE, SKIB and SKIC using SRK manifolds or
single-pipe metering valves series SMIE, SMIB mounted directly in the lubricated place.
3 DESCRIPTION
The main parts of the unit are a plastic tank and tank lid, on which the main components of the unit are
mounted, which are a gear pump with electric motor, float level meter for SAO units, diaphragm level
meter for SAG units with electric switch, filling neck with filling network and outlet fitting with
manometer. Manometer only at the customer's request. There are a change-over, relief, and safety
valve on the plastic gear pump holder.
In addition, some types of lubrication units (SAO P3, P4, P5, SAG P3, P4, P5) are available with an
internal pressure switch or pressure switch and automatic control (SAO P2, P4, SAG P2, P4). The
tank lid is closed with a plastic cover. For lubrication units equipped with automatic control, there is a
manual button on the front of the tank lid to start one lubrication time and 3 signalling LEDs. The
individual indicators indicate: green light - connected voltage, yellow light - unit running, red light
flashing - lack of lubricant in the tanks (lubricant pressure level has dropped below the permitted
minimum), red light is constantly lit - during the lubrication period there was no work cycle lubrication
circuit (pressure switch did not turn on).
SAO, SAG lubrication units are units in a variant design, with a plastic fuel tank with an optional
volume of 3 or 6 litres. The nominal supplied amount of lubricant is uniform 100 cm
3
/ min for all unit
designs, with a maximum working pressure of 24 bar (SAO) and 30 bar (SAG). Electric motors are
standardly supplied in 115 V AC, 230 V AC and 24 V DC single-phase, other voltages consult the
supplier.
4 OPERATION
After getting operation of the lubrication unit, the gear pump, driven by an electric motor, carries the
lubricant in the relief valve, in which the piston moves and closes the discharge opening. The lubricant
pressure in the change-over valve increases, where the working cuff moves and closes its drain hole.
The entire lubrication circuit is now closed and the lubricant starts to flow around the sealing edge of
the working rubber cuff of the change-over valve into the lubrication circuit, and all the metering valves
in the circuit perform their stroke and deliver the lubricant to the lubricated points. When the gear
pump is stopped, the relief valve spring moves its piston, which opens the drain hole. The pressure in
the change-over valve drops, the working cuff opens the drain hole, through which part of the oil
escapes from the lubrication circuit back into the tank and the pressure in the circuit drops. After the
pressure drop in the circuit, the closing rubber cuffs in the single-pipe metering valves are released,

the dispensing pistons pressed by the springs are moved to the initial position while the oil is moved to
the space above the dispensing pistons. This completes one lubrication of lubricated points, i.e., one
lubrication cycle. After restarting the electric motor, the above procedure will be repeated.

By pressing the intermediate lubrication button between on the unit panel, an extra lubrication of the
lubricated parts in the circuit is started during the break period, one lubrication cycle, during which the
working pressure and lubricant level in the unit tanks are also checked. The manual intermediate
button must always be used after refilling the lubricant in the tanks, if it has dropped below the
minimum level and the minimum alarm has been triggered, or in case of repair of the lubrication circuit
after a pressure alarm.

11 SETTING WORKING PATAMETERS
The control automation performs automatic switching on and off of the electric motor of the aggregate
during the set lubrication cycles, which remain from the lubrication time and the lubrication break time.
In addition, it evaluates the status of the working pressure of the lubricants in the circuit, and provides
information on the status of the minimum level of lubricants in the tanks.
Setting the lubrication cycles on the automatic control unit is done before connecting the aggregate
under voltage to the electrical network and after dismantling the plastic cover of the tank lid by
choosing the combination of the contact positions of the three switches on the automatic control unit.
The duration of the lubrication break can be set in a wide range in two modes, namely in the time
mode, when we choose the length of the break in minutes and hours, or in pulses, when the break
period consists of the time in which the control automation receives the setting of the number of
voltage pulses from an external pulse source, for example from inductive switches.
The values of the lubrication time and the break time are set step by step.
The lubrication time can be selected from 8-time values in the range from 5s to 90s on the DS2 switch.
The break time can be set using a combination of switches DS1 and DS3, the length of the break is
the value next to the scheme of the switch DS1 in the range of 1 min to 1000 min or 1 hour to 21
hours.
All setting options are shown in Figure 19 and 21.

The selection of lubrication time or the selection of a break at the beginning of the lubrication cycle can
be set with jumper J1:
- the lubrication cycle begins with the lubrication period J1
- the lubrication cycle begins with a break period J1
The red LED light informing about the achievement of the working pressure during the lubrication
period is connected to the jumper (bridge) J2. In the event that the jumper is not connected and the
lubrication circuit becomes impassable, the control automation will not evaluate this condition as a
fault, the lubrication will not be interrupted and the lubrication cycles will take place at the set times.
The grease supplied by the gear pump will return to the tank through the safety valve, overloading the
electric motor and overheating.

Figure 23 Layout of switches
For lubrication circuits with a longer break period selected, the function of the intermediate lubrication
mode can be used. In this mode, by pressing a button on the unit panel, during the break period,
extraordinary lubrication of the lubricated points in the circuit can be started, one lubrication cycle,
during which the working pressure and lubricant level in the unit tank are also checked. At the same
time, the loaded break time will be automatically reset. The manual intermediate lubrication button
must always be used after topping up the lubricant in the tank, if it has dropped below the minimum
level and the minimum level alarm has been triggered (flashing LED light), or in case of repair of the
lubrication circuit after a pressure switch alarm (solid LED light).
For SAO P2, SAG P2 versions that are not equipped with an internal pressure switch, it is necessary
to properly connect the external pressure switch to the control system. If the pressure switch is not
connected and jumper J2 on the automatic control is in the "connected" position, at the end of the
lubrication period, a malfunction is signalled by a permanently lit red LED, with the simultaneous stop
of the next lubrication run.
We return the automatic control to normal mode by pressing the manual button on the panel, after
which one lubrication period will take place and the set lubrication cycles will continue. The control
automation is not equipped with a fixed memory, therefore, when the voltage is interrupted, the loaded
break time is reset to zero.
SAO P4, SAG P4 lubrication aggregates are equipped with a pressure switch and the same applies to
them as for SAO P2 and SAG P2 aggregates.
It is possible to connect external signalling of the state of the minimum oil level in the tank to the
automatic control. Since the output of this signalling is switched via a relay, it is possible to connect the
machine shutdown to this output.
For the proper functioning of the lubrication unit, the lubrication circuit must be completely vented, it is
also necessary to maintain the required cleanliness of the pipeline, i.e., remove burrs and other dirt
from the pipe before assembly.
12 BASIC SETTINGS
The basic automatic setting depends on the working conditions of the lubrication units.
