FOCUS 1.1 The BOGE control concept
Part 1: FOCUS 1.1 The BOGE control concept
Installation FOCUS is a compressor control unit.
It is installed into the switch cabinet as part of the compressor and serves as
a compressor control device.
Prior to commissioning and before accomplishing any kind of maintenance or
servicing work please read the functional descriptions of both control and com-
pressor carefully. First and foremost observe the Safety notes in chapter 1 of
the functional description of the compressor.
Power input
Terminals A1 and A2 for 24V AC / DC
An interruption of the power supply is effected by means of the mains discon-
nector of the compressor.
Modules
The basic equipment of the FOCUS consists of a basic module and a keypad/
display unit (TAN).
Amongst others the following modules are optionally available:
– with a – second – RS485 interface for the connection of additional com-
pressors if the serial interface is used for other purposes
– with changeover contact relay; function can be selected by rotary switch
– system pressure module for a system pressure transmitter on the master
compressor
Interconnection of the modules may only be completed in a currentless state
using the provided leads supplied with the equipment.

jecting parts resp. a crushing hazard because of flaps or doors standing
open!
The compressor may only be operated with all flaps and doors closed!

FOCUS 1.2 Operation
Page 4 BOGE FOCUS compressor control for piston compressors
Switch on the control After switching on the compressor supply voltage, the display shows the name
of the control, the manufacturer's name and version number – as described
under version display.
First a parameter adjustment between basic module and TAN is performed
resp. and if applicable the registration of connected and not yet registered ad-
ditional modules.
When the process is finished, either the symbol of the OFF key flashes in
the display, which is acknowledged by pressing the OFF key to leave the
display, or auto re-start and / or remote on / off is active and the display counts
down after voltage returns (mains outage), usually starting with the set auto
re-starting time [s]*. When this time is expired the compressor switches to
Ready status and starts automatically, as soon as the prerequisites are fulfilled.
If an interference is pending when voltage is switched on, it is displayed right
after parameter reconciliation (see also section „1.7 Warning message / Fault
message“, page 27).
* The time is automatically extended temporarily if there are too many motor starts in short suc-
cession.
Switch on the
compressor
At first OFF should be displayed in the bottom frame – the status display of the
compressor.
If this is the case, the compressor can be put in the READY state by pressing
the -key.
A green LED signals that the compressor is ready for operation and the pres-
sure control is active – as long as no "Timer-Off" is due or an external pressure
control was parameterized.
If EMERGENCY STOP is displayed for the compressor status the Emergency-
Stop button has to be unlocked first.
If the status display shows Fault, the control is faulty and the malfunction has
to be corrected first (see also section „1.7 Warning message / Fault message“,
page 27).
Ready If the compressor status Ready is displayed, the compressor is in the "ready-
for-operation" status. That means that the compressor automatically (re)starts
pressure and / or time controlled – as long as the conditions to do so are ful-
filled.
Caution: Risk of injury!
If the compressor is not closed there is a risk of injury due to rotating or pro-
jecting parts resp. a crushing hazard because of flaps or doors standing
open!
The compressor may only be operated with all flaps and doors closed!

FOCUS 1.2 Operation
Run-up phase The compressor motor is started and run up as already described under
„ Ready“, page 4 The status display changes from Ready to Run-up.
To be able to do so, the system pressure* at the compressor must be de-
creased and the motor spinning time finished.
For the star / delta contactor combination applies: First the star contactor and
20 ms later the mains contactor is switched on. The display Run-up signals the
corresponding status of the control.
* If a system pressure sensor is present – the sensor input is optionally used for suction pressure
monitoring.
Load operation The Run-up resp. Star phase is finished after termination of the run-up time.
The control activates the transport valve.
Compressors which are controlled accordingly now change into the delta
switching and the display shows load.
Idling By setting a follow-up time – preset to 0 seconds – and / or exceeding of the
maximum permissible motor switching operations, suitable compressor types
may go through an idling phase after completion of a load run phase.
Otherwise, the control switches off the motor at once – and the compressor
switches back to Ready state.
If the net pressure drops below the set minimum pressure (pmin), the compres-
sor control may automatically change from idling to load operation – the com-
pressor continues with the output.
* Multi-stage compressors (determined by P=41) are not capable of running idle due to delayed
valve control, so that a sufficiently large receiver/net volume and sufficiently large interval between
the upper and the lower pressure target value are required for motor switching operation limitation!
Switch off the
compressor
With the OFF key or via Remote-Off the compressor is switched off. The
pressure control is deactivated. Immediately, Off is displayed in the compres-
sor status display and the green LED goes out.
Maintenance When operating the control the battery voltage has to be checked from time to
time. If the voltage drops too far a warning message is created. In this case
the battery has to be replaced.
The display of the TAN has to be cleaned with a damped yet not wet cloth from
time to time. As detergents customary household detergents for greasy sur-
faces can be used. No further maintenance is required for the control.

Maintenance With the next actuation of the -key you get to the servicing display. Here the
information concerning the servicing times are displayed.
Operating times By pressing the -key you get to the operating times display. On this menu
page the operating times of the compressor are displayed.
Leakage monitor Pressing the key in the operating hours display causes the control display
to show "leakage". The display serves to enable you to determine the energy
loss resulting from any potential leaks in your compressed air network.
To this purpose, the control unit measures the time period duration of the
operating loads during which, under normal circumstances, no production of
compressed air takes place, as for example over night or operation down-
times.
This, however, is conditioned on the fact that operational compressed air pro-
duction be discontinued for a protracted period of time and that the compres-
sor be set into the "ready" mode by means of the control system. In case of a
potential pressure reduction below the preset minimum pressure value result-
ing from leaks in the compressed air network, this compressor automatically
switches into the operating mode in order to recover the set -pressure range.
The leakage measurement serves to record the duration of the operating load
times and to extrapolate them for the whole year. This allows you to quantify
any leakages and to easily determine their portion of additional costs due to
any energy losses.

FOCUS 1.3 Display information
Page 8 BOGE FOCUS compressor control for piston compressors
A potential leakage is either measured by a single (LE) or continuous (Lc)
value measurement:
In case of single leakage measurement a single measurement operation
over six hours serves to determine the hourly operating load times per year
due to leakage.
In order to obtain a precise value it is imperative that no operational com-
pressed air consumption take place during measurement, viz. production is to
be shut off for at least six hours. If measurement is actuated by means of the
control system, measurement will be deferred by six hours. This allows you to
activate the leakage function already in the afternoon causing the measuring
operation to start in the evening (six hours later) to continue over night.
Unlike continuous value measurement, single value measurement is also pos-
sible if several compressors are being operated in the basic load mode at the
same time. Starting separate single value measurement of each compressor
enables you, after a six-hour measurement period, to read and to add up all
of the single values of the compressor control units. Their total value corre-
sponds to the annual number of hours of operating load times as a result of
leakage in your compressed air networks.
Continuous leakage measurement is designed to continuously calculate
operating load values at six-hour intervals.
Unlike single leakage measurement, continuous leakage measurement can
also be started during current daily production with measurement starting at
once. The first value obtained after a six-hour period will probably be distorted
since any operational compressed air production will be added to any potential
leakage related operating load. Most probably, however, no operational pro-
duction will be in effect during any subsequent value measurement. The then
obtained value, which is exclusively due to leakage, will be smaller than the
first obtained value. The control system is designed to always display the
smallest value of all measurements, in this case, however, the last obtained
value. This means that any distorted calculation of production operating loads
will be excluded.
In order to determine exact leakage measurement values make sure that, dur-
ing a time frame of 12 hours, there will in all probability be no operational com-
pressed air production.
Single leakage
measurement
(LE)
The abbreviation LE stands for "single leakage measurement".
The displayed value shows the annual operating load times due
to leakage.
Continuous leakage
measurement
(Lc / LC)
The abbreviation Lc stands for "continuous leakage measure-
ment“. The displayed value shows the annual operating load
times due to leakage.
When the abbreviation LC is displayed, continuous measure-
ment has been carried out for more than a week.

BOGE FOCUS compressor control for piston compressors Page 9
FOCUS 1.3 Display information
Start leakage measure-
ment
After editing "leakage" in the control display, please proceed as follows in or-
der to start either of the available measurement methods.
Start single measurement
Single leakage measurement will not start but six hours after actuation of this
process. Your are herefore requested to make sure
– that, after the deferred start of the measurement process no operational
compressed air production will take place over a period of six hours.
– that the compressor be set into the "ready" mode by means of the control
unit and that the green LED of the control be lit.
– that, when using the "external flow release" the external flow release may
not be shut off neither manually nor by the switch clock.
In order to start single measurement:
1. Keep ENTER key pressed for three seconds.
The value next to LE starts blinking.
2. Press ENTER key again for three seconds.
The number 9999 appears and single value measurement will start in six
hours. hours. After a period of twelve hours, the single measurement value
will be displayed. This value will be saved until a new measurement proc-
ess is carried out.
If, during measurement, a power failure takes place the number 9980 will be
displayed. In such case it is recommended to repeat the measurement proc-
ess at a later stage.
If, during measurement, the compressor is put out of operation the number
9990 will be displayed, i.e. the compressor is switched off and the energy loss
due to leakage could not be properly determined during said measurement.
In this case, too, the measurement process should be repeated at a later stage
while making sure that the compressor be switched off during measurement.
If the value next to LE starts blinking and no measurement is to carried out:
–PressINFO key .
The value will stop blinking. The measurement process is not started. By press-
ing the key, you get to the „Operating times“display.
Starting continuous measurement
Continuous leakage measurement will start immediately. Make sure
– that during the following days, at least for once during a time frame of
12 hours, no operational compressed air production takes place.
– that the compressor be set into the "ready" mode by means of the control
unit and that the green LED of the control be lit.
In order to start continuous measurement:
1. Keep ENTER key pressed for three seconds.
The value next to LE starts blinking.
2. Press the key .
The value next to Lc starts blinking.
3. Press ENTER key for three seconds.
The number 9999 appears next to Lc. Continuous measurement will start
immediately and keep being carried out. After the twelve-hour time frame,
during which no operational production has taken place, has been exceed-
ed a sound measurement value is obtained.

The control system will always save the lowest value. A search for the lowest
value – as a background process – will be restarted once a week. This allows,
after expiry of another week, a higher value compared to the one of the previ-
ous week to be displayed if the measured minimum value has increased dur-
ing that period. Any potential increase of leakages in the compressed air net-
work will therefore also be possible to be determined.
Any power failures during measurement will not be indicated by a sequence of
digits because new values will be calculated every six hours and because any
such power failure during measurement will not prevent the values of the sub-
sequent measurement to be displayed.
If the value next to Lc is blinking and no measurement is intended to be carried
out:
– Press INFO key
The value will stop blinking, and the measurement process is not started.
By pressing the key, you get to the „Operating times“display.
Info # 1 Pressing the key in the operating hours display causes the control display
to show „Info # 1“. This display serves to show information on the compressor
set-up.

Info # 2 The information to the control settings as master control resp. the current sta-
tus of the integrated timer are displayed here.
The priority sequence is only displayed if the number of compressors in the
base load switch control is above 1. In case the number of compressors is set
to 1, n / a is displayed here.
The display of the priority sequence shows the currently effective sequence for
selecting the compressors. Depending on the setting the priority sequence
is changed cyclically (base load switch control) or selected by means of the
switch clock.
For each parameterized compressor the current output signal status, the cur-
rent priority level and the time until the next priority change, with switched-on
base load switch control, is displayed. If only the switch clock is active (cyclic
changing time set to 0) no time is displayed.
Meaning:
C1 C2 C3 means, that the compressors 1–3 are connected and the sequence
1, 2, 3 is chosen – in this case none of the compressors receives an output
signal.
C1 C3 C2 means as in the first example, that the compressors 1–3 are param-
eterized although they are selected in the sequence 1, 3 and 2. Furthermore,
compressor 1 receives an output signal in this case.
The output signal status is shown by means of a black background in the graph-
ical presentation of the compressors in the display.
Date / Time This menu page shows the current setting of the real-time-clock.
The time is displayed in hours, minutes and seconds and the date with day of

P012 pmax Pressure range 1
Pressure range 1 is the default pressure setting for the compressor.
Here the upper pressure target value for pressure range 1 is set. As soon as
the net pressure has reached pmax the compressor changes from load run to
idling.
P013 pmin Pressure range 1
Pressure range 1 is the default pressure setting for the compressor.
Here the bottom pressure target value for pressure range 1 is set. If the com-
pressor is in the Ready state and the net pressure drops below pmin, the com-
pressor starts with the output.
P014 pmax Pressure range 2
Pressure range 2 offers the possibility for pressure decreases and the value
must not be set above that of pressure range 1.
Note!
If pmax is set so that pmin is larger or the minimum hysteresis (P011) is not
complied with, confirming it with the -key will force you to edit P013.
Note!
If the pressure range selection is effectuated by a master control or the exter-
nal contact you have to observe when setting the pressure ranges, that in
case of a power failure or fault of the master control, the compressor control
eventually falls back on this pressure range.
