1.1 General safety instructions

WARNING!

Failure to adhere to these recommendations can result in mechanical failure,
property damange and serious injury or death.
All air and water inlet, and air and water discharge pipework to and from the
inlet and discharge port connections must take into account vibration, pul­sations, temperature, maximum pressure applied, corrosion and chemical
resistance. In addition, it should be noted that lubricated compressors will
discharge some oil into the air stream; therefore, compatibilty between dis­charge piping, system accessories and software must be assured.
For the foregoing reasons, the use of plastic piping, and soldered copper
fittings as discharge piping is not recommended. In addition, flexible joints
and/or flex lines can only be considered for such purposes if their specifi­cations fit the operating parameters of the system.
It is the responsibility of the installer and owner to provide the appropriate
service pipework to and from the machine.

WARNING!
Statement concerning the inadvertent breathing of compressed air

exhaust.

The purchaser/user shall ensure that adequate ventilation and make up air
are provided if a non-BAP designated compressor supplies air in a confined
area to air consuming devices such as air motors, air tools, solenoids, air
cylinders, air guns, nozzles, etc. The compressed air discharge stream may
contain residual coolants/lubricants/carbon monoxide and condensable
hydrocarbons or other materials which may be hazardous to health with pro­longed inhalation.

2.2 Function description

Function principle
of the air end

Air circuit

The air end operates according to the displacement principle. In the housing,
the main and secondary screws are driven by means of an electric motor
and V-belt.
Both screws have screw-shaped profiles, intermeshing without contact.
Together with the housing wall, these screws form chambers which gradually
reduce in size, seen in air flow direction.
Rotation of the rotors causes the air taken in to be compressed to the final
pressure in the chambers.
During compression oil is continuously injected into the air end. This having
a cooling, sealing and lubricating function.

Components of
the air circuit

1 = Intake filter

The intake filter cleans the air suctioned by the air end.

2 = Intake regulator

The intake regulator opens (load operation) or closes (idling operation or
standstill) the intake line depending on the operating condition of the com­pressor.

3 = Air end

The air end compresses the intake air.

4 = Compressed air/oil receiver

The compressed air separates from the oil under the force of gravity in the
compressed air/oil receiver.

5 = Oil separator

The oil separator separates the residual oil contained in the compressed air.

6 = Minimum pressure check valve

The minimum pressure check valve does not open until the system pressure
has increased to 3.5 bar (51 psig). This causes a rapid build-up of the system
pressure and ensures lubrication in the starting phase. Once the compressor

flowing back out of the mains line.

2.2 Function description

Oil circuit

The oil injected into the air end has the following function:

– It dissipates the compression heat (cooling).
– It seals the gaps between the screws and between the screws and housing.
– It lubricates the bearings.

Components of the oil circuit

1 = Compressed air/oil receiver

The oil separated from the compressed air through the force of gravity collects
in the compressed air/oil receiver.
The system pressure forces it out of the receiver into the air end.

2 = Thermostatic oil control valve

Depending on the oil temperature, the thermostatic oil control valve either
allows the oil to pass through the oil cooler or through a bypass (e.g. in the
starting phase).
Thus the oil constantly maintains its optimum operating temperature.

3 = Oil cooler (air or water cooled)
The oil cooler cools down the hot oil to operating temperature.

4 = Oil filter

The oil filter traps impurities in the oil.

5 = Air end

The injected oil returns to the compressed air/oil receiver together with the
compressed air. There, it is separated through the force of gravity.

6 = Drainage line

The collectet oil from the oil-separator is drained back to the air end into the
oil circuit via the drainage line.

2.3 Compressor control

Supply pressure

Operating states

For the compressor, the pressure downstream of the check valve is termed
the supply pressure. The control system switches the compressor on and off
during operation depending on the supply pressure.

All screw compressor controls are based on three basic operating states:

1. Load operation

– The compressor delivers its maximum amount of compressed air.
– It consumes its maximum energy.

2. Idling operation

– The compressor runs but does not deliver any compressed air.
– It consumes approx. 75% less energy than in load operation.
– When compressed air is required, it switches to load operation with-

out delay.

– Idling operation reduces switching frequencies which can damage the

drive motor, and reduces wear of the system.

3. Standstill ready for operation

– The compressor is standing still but ready for operation.
– When compressed air is required, it switches automatically to load

operation.

Operating modes

Short operating
times

The two most important operating modes are achieved by combining the
three operating states:

1. Intermittent operation

In intermittent operation the energy balance is perfect.

– The compressor operates in load operation.
– Upon reaching the switch-off pressure p

the compressor switches

max

to standstill. It does not consume any energy.

– Once the pressure has dropped to the switch-on pressure p

min

the

compressor switches back to load operation.

2. Continuous operation

Continuous operation limits the drive motor switching cycles and reduces
wear to the system.

– The compressor operates in load operation.
– Upon reaching the switch-off pressure p

the compressor switches

max

to idling operation.

– Once the pressure has dropped to the switch-on pressure p

min

the

compressor switches from idling operation back to load operation.

CAUTION!

During short operating times, the compressor does not reach its operating
temperature. It operates below the dew point. The generated condensate
mixes with the oil. The lubricating ability of the oil is reduced. This leads to
damage on the air end.
It is of utmost importance to consult BOGE, if you operate your system with
short operating times.

sor either switches off (intermittent operation) or switches to idling operation
(continuous operation).

The proportional controller is an additional control device intervening in the
sequences of the intake regulator.

The intake regulator only opens as far as necessary to supply the current
compressed air requirement. Thus the compressor saves compression
energy.

A compressor with proportional controller is able to supply its ’delivered
quantity variable between 0% and 100%. However, the energy consumption
does not reduce accordingly. Therefore, a control is only practical between
50% and 100% of the delivered quantity.

The proportional controller is factory set to a delivered quantity between
50% and 100% of the compressor capacity.

The proportional controller closes when the desired delivered quantity has
dropped below 50% of the compressor capacity. The compressor then oper­ates in idling operation (continuous operation) or switches off (intermittent
operation).

2.5 Safety and monitoring devices

General

Safety temperature
limiting device

Safety valve

The safety devices guarantee a high degree of operational safety, in connec­tion with the BOGE monitoring system.

When one of the safety devices responds, the control system reacts as follows:

– The compressor is immediately switched off.
– A flashing fault number in the left field of the display indicates the cause

of the fault.

DANGER!

Do not operate the compressor without built-in safety devices.
Do not dismantle the safety devices or put them out of operation.

Safety temperature limiting device switches off the compressor once the
maximum admissible final compression temperature has been reached.
The compressor does not switch on when dropping below the minimum
temperature.

– Switch off the compressor (OFF button). Fault is acknowledged.
– Rectify the fault.
– Switch on the compressor (ON button).

Safety valve  on the compressed air/oil receiver prevents the maximum
admissible pressure being exceeded. When the maximum pressure is ex­ceeded (e.g. incorrect setting of the operating pressure switch), the entire
delivery volume of the compressor is ejected.

Monitoring the drive
and fan motor

Rotational direction
monitoring

Safety pressure switch
(option)

System pressure
build-up (option)

The following monitoring devices are standard for BOGE control systems:
The drive motor is monitored by PTC resistors.
The fan motor is monitored by overcurrent/overload release units.

The pressure switch checks the rotational direction of the drive motor each
time the system starts up.
The pressure switch for the rotational direction is placed next to the operat­ing pressure switch.

The safety pressure switch prevents the maximum admissible system pres­sure being exceeded. The switch-off pressure is below the response pres­sure of the safety valve.

The system pressure build-up unit monitors the system pressure build-up
when the compressor starts up.

5.1 Safety instructions

DANGER!

Ensure that maintenance work is only carried out by specialists or appro­priately trained person.

– Prior to starting any maintenance work, always stop the compressor as

described in these operating instructions prior to removing any cladding
or safety devices. Refit the cladding or safety devices immediately upon
completion of the maintenance work.

– Only use original spare parts, compressor oils and operating materials

released by BOGE for the maintenance work.

– When the automatic restart (Auto-Restart) is activated, the compressor

restart automatically following a voltage loss.
Prerequisite: The net pressure is lower than the switch-on pressure.

Safety precautions

DANGER: Risk of injury!

Always adhere to the specified operating method described below for all
maintenance work. Never omit a single safety step!
Otherwise you will risk injury from restarting, electric shock or parts which
may fly off.

Prior to all maintenance work:

1. Switch off the compressor using the OFF button.

2. Switch off the main switch and secure it against unintentional switch­on.

3. Check to ensure that all machine elements are definitely isolated.

4. Separate the compressor from the compressed air network by closing
the ball valve at the compressed air outlet.

5. Vent the compressor.
To this effect open the safety valve on the combined compressed air­oil receiver as follows:

– Turn the knurled nut counterclockwise until you can feel a resilient

resistance.

– Tun the knurled nut a little further.

Any possibly existing air will escape.
The system pressure gauge will indicate a pressure of 0 bar.

– Once the residual air has completely escaped from the system,

firmly retighten the knurled nut.

6. Remove all safety cladding necessary to perform the maintenance
work.

Once the maintenance work has been concluded:

7. Reattach all removed safety cladding.

8. Open the ball valve at the compressed air outlet.

9. Prior to switching on again, check whether anyone else is working on
the compressor!

As a rule, the bearings of the drive motors are provided with a maintenance
free permanent lubrication. The drive motor of some series are equipped

with a post-lubricating unit. These motors can be easily recognised by the
two grease nipples on the upper side of the housing. In addition, plates
on the compressor indicate the type of motor lubrication.

Under normal operating conditions (coolant temperature max. 105°F,
continous operation) the bearings are maintenance free for the service life.

Bearing service life: Mains frequency Operating hours

Maintenance

5.3 Regular maintenance work

Drive motors with
lubrication device

Motors with lubrication devices are easily recognised by the two grease nip­ples on the top of the cover. Please check which motor is installed in your
compressor and service it according to the respective instructions.

Lubricate the bearings of the drive motor at the prescribed intervals so as
not to sustain damage due to lack of lubricant.

The motors with lubrication device can be recognised by the two grease nip­ples on the top of the cover. Adhesive plates on the compressor also indicate
the motor lubrication. On motors with lubrication devices, regular greasing
belongs to the scope of maintenance.

The lubrication intervals, quantity and type of grease are given on the
type plate or a separate plate. For lubrication, the required quantity is
pressed through the nipple into the bearing with a grease gun while
the compressor is running.

DANGER: Risk of injury!

Always exercise great caution when lubricating the bearings with the com­pressor running and observe all safety precautions! Never put your hand in
the area of the V-belt and the fan wheel. Fitted safety devices and cladding
may not be removed.

CAUTION!

Always use the same type of grease for lubrication. The lubricating ability can
be sharply reduced if different types of greases are mixed.

If you intend to use a different type of grease:
– have the bearings removed and thoroughly cleaned prior to filling with

new grease.

Please always observe the specified lubrication intervals and quantities of
grease.

Even over-greasing and an excess of lubricant can the bearings to be de­stroyed.

Maintenance

5.3 Regular maintenance work

Servicing drive motor

The drive motors have an automatic lubricating device (see figure).
There is a lubricating nipple on the A bearing and B bearing side of the motor.
The lubricating nipple is connected with the automatic lubricating device via
a tube.
The tubes are already filled with grease. When the tubes are replaced, they
must be filled with grease.
The type of grease is indicated on the lubrication unit of the compressor
(see Fig. 5.5 below).

Voltage is supplied from the switch cabinet.

Both LC units (LC = lubrication canister) are designed for 1 year in three­shift operation. After one year, the canisters must be replaced because
of lubricant ageing, no matter how much lubricant they have.

So as to comply with the necessary lubricating deadlines, the coding switches
"VOL" and "TIME" of the drives are preset in the factory according to table

7.2 of the Operating Instructions for CONTROL TIME.

Set values:
– LC unit S250 for A bearing: 2.89 cm³/ per 100 operating hours

For information regarding operating and maintenance to CONTROL TIME,
please read enclosed operating instructions.

– When the compressor is operated at extreme ambient temperatures.
– When the intake air is extremely soiled.

Building up a pressure cushion

The combined compressed air / oil receiver is located at the lowest point of
the system. Therefore, a light pressure cushion (approx. 30 psig system
pressure) must be applied to drain the oil. This pressure cushion forces the
oil through the drain hose into a suitable collecting basin.

DANGER: Risk of injury!

Switch off the main switch and secure it against unintentional switch-on.
– Screw cap nut  onto the vent hole of the solenoid valve on the suction

controller by hand.
The cap nut (M8) is located in the storage compartment of the switch
cabinet.

CAUTION!

Never use any tools to screw on the cap nut!
Damage af the solenoid valve might result.

– Switch on the compressor again and allow it to start up.

If necessary, let out some air from the compressed air receiver until the
switch-on pressure of the compressor is reached.

– Switch off the compressor at approx. 30 – 44 psig system pressure using

the EMERGENCY-OFF-button.

DANGER: Risk of injury!

Switch off the main switch and secure it against unintentional switch-on.

– Slowly loosen cap nut  until compressed air escapes.
– Let off compressed air until the system pressure gauge shows a residual

pressure of approx. 30 psig.

– Tighten cap nut  by hand.

DANGER: Risk of injury!

Danger of burning due to hot oil!

Draining old oil

– Place the oil drain hose into a suitable container .
– Slowly open the stop valve.

The pressure cushion forces the oil into the container.

– Once the compressed air/oil receiver has been completely drained, close

the stop valve.

– Remove the cap nut from the solenoid valve.

Maintenance

5.3 Regular maintenance work

– Remove oil filler screw  on the compressed air/oil cooler and drain the

residual oil (max. 5 litres) into a suitable container.

– Reinsert the oil filler screw together with a new copper sealing ring.
– Change oil filter (Procedure as described above).
– Change oil separators (Procedure as described above).

Filling with new oil:

– Fill up to the edge of the thread of the filling socket (max.).

(Procedure as described above).

CAUTION!
After each oil change you have to fill a small quantity of oil into the suction

controller before starting the compressor.
For oil quantity and procedure see chapter "Commissioning following extended
stoppages".

CAUTION!

Always fill with the same oil type as previously used.
Never mix different oil types and brands.

The oil circuit must be flushed prior to changing the oil type.

– Close safety sound insulation hood.
– Open ball valve at the compressed air outlet.
– Reattach cladding on the maintenance side.
– Conduct trial run.

DANGER: Risk of injury!

Switch off the main switch and secure it against unintentional switch-on.
– Check the oil filters and oil separators for leaks and tighten by hand,

if necessary (procedure as described above).

– Check oil level (procedure as described above).

Top up oil losses, if any.

5.3 Regular maintenance work

Flushing the oil circuit

Cleaning the
compressed air / oil
cooling unit
(air cooling)

Flushing the oil circuit with clean oil becomes necessary:

– When the oil is excessively soiled.
– Prior to changing the oil type.

CAUTION!

Detailed information as to the flushing with BOGE oils you can obtain from
the following service number.

770 - 874 -1570



Cleaning: – After 1500 operating hours,

however, at the latest after one year.

The service life of the compressed air/oil cooling unit depends on the
degree of soiling (dust, oil vapour) of the suctioned cooling air. Extreme
external soiling of the cooling unit leads to an increased temperature
in the oil circuit.

– Switch off the compressor using the OFF button.

DANGER: Risk of injury!

Switch off the main switch and secure it against unintentional switch-on.

– Remove cladding on the maintenance side.
– Unscrew the maintenance flap on the air guidance box.
– Remove accumulated soiling with a fibre brush.

CAUTION!

Do not use any sharp objects for cleaning!
These could damage the cooling unit!

– Blow down the dirt with compressed air  in the opposite direction to the

normal cooling air flow. Clean out the dirt using an industrial vacuum
cleaner  (see Fig.).

If the cooling unit is excessively soiled (cleaning is no longer possible with
compressed air), have it disassembled and cleaned by BOGE service.

2. Setting the proportional controller

Displace the control range of the proportional controller by turning cap .
– Increase pressure level:

Turn cap  clockwise.

– Reduce pressure level:

Turn cap  counterclockwise.

Always set the proportional controller higher than the bottom operat­ing pressure value (P

min

)!

3. Pressure switch for infinitely variable capacity control

The low pressure switch for the infinitely variable capacity control limits the
reduction of the delivered quantity and switches the compressor in the event
of less than 50 % delivered quantity into idling operation or off.

Note: Demonstration example. Compressor may only be operated with the switch cabinet

closed and all panels fitted.

Checking
the safety valve

DANGER: Risk of injury!

Because a hot air-oil mixture will escape when checking the safety valve
with running compressor only trained personnel or specialists should carry
out this work!

Check: – After approx. 3000 operating hours,

however, at least once a year.

Check safety valve by opening the screw plug .

DANGER: Risk of injury!

Danger of burning due to hot oil!
Take extreme care when checking the safety valve with the compressor

running taking all safety measures into consideration. Wear eye protection.
A hot air-oil mixture escapes when opening!
– Open the threaded plug  counterclockwise.

The compressed air escapes.

– Tighten the threaded plug by turning clockwise.
