Safety instructions
for operating
the control unit
1. The control unit may only be put into operation after these instructions
have been read and properly understood.
2. The control unit may only be used for the purpose described in these
instructions.
3. The user/owner must ensure
– that only trained and and authorised staff use the control unit.
– that the operating personnel are thoroughly familiar with and follow all
safety instructions.
– that the control unit is only used in a safe operating condition.
4. The unit may only be used with the options recommended or approved by
the manufacturer.
5. The unit may never be used if one or more parts are damaged, not operating correctly, or if damage can be seen or is suspected.
trinity integrated into
the compressor
If the control voltage of the compressor is switched off all the other compressors (electrically connected to the trinity) are released at the same time.
Exception „Pressure
sensor inside
compressor switch
cabinet“
Normally the separately shipped pressure transmitter of the trinity is installed
directly to the central compressed air receiver of the compressed air network.
Should, as an exception, the pressure transmitter of the trinity be installed in
the switch cabinet of the compressor (like the compressor pressure transmitter) and not on the external receiver, the following steps are to be observed: If
the compressor with the integrated trinity is shut off the compressed air network (e.g by shut-off valve or ball valve) the pressure transmitter can no longer
obtain any information from the compressed air network and all compressors
connected to the trinity are no longer controlled correctly. It is absolutely necessary that the pressure transmitter of the trinity is always impinged with network pressure!
Safety instructions for
repair of the control unit
1. Adjustments, troubleshooting and repairs may only be carried out by
qualified systems electricians (see DIN VDE 0100 or DIN VDE 0113,
EN 60204).
2. Before carrying out repairs:
– switch off the voltage
– check that none of the parts are under power.
Attention!
Non-compliance with the following safety instructions may lead to physical
injury and damage to the control unit. In addition to the instructions in this
manual, the general safety and accident prevention rules must always be followed!
General 1.2 Introduction
Page 2 BOGE Operating instructions trinity
3. Work on components and and facilities under power is not allowed. The
exceptions to this are specified in the appropriate rules, e.g., DIN VDE
0105.
4. Only the original spare parts approved by BOGE may be used for repair
work.
1.2 Introduction
The purpose of these operating instructions is to describe the operation and
possible applications of the control unit.
These instructions contain important information describing how to use several compressors safely, economically and correctly, with the aid of a trinity
control unit.
Compliance with these instructions helps to avert danger, reduce repair costs
and down-times, and increases the reliability and service life of the compressors.
The instructions contain important information about necessary parameters
and their adjustments. They are also a source of assistance in the case of malfunctions.
These instructions must be available to the operating staff at all times at the
place the control unit and compressors are used.
The instructions must be read and followed by all persons who carry out the
following work on the control unit:
– operation, including troubleshooting
– commissioning
Correct usage
The BOGE Multisystem control unit together with its options is solely designed
for controlling several screw and piston compressors made by BOGE.
The unit may only be operated and adjusted by trained and authorised persons.
Prerequisites for the compressors to be controlled
If the trinity control is ordered with the compressors, we install the interface in
the compressors at the factory (mandatory option). If the compressors are
already on site, the machines must be prepared for connection to the trinity.
These prerequsites are normally:
two terminals in series with the operating switch installed in the compressor or
a suitabel connection (digital input) for a master pressure control.
Attention!
Care must be taken with equipment from different makers; please always
obtain approval from the factory.

General 1.3 Components / Range of application
Electrical connections
13 connecting terminals in tension spring technology – can be operated from
above:
1. Two alternatively useable inputs for the two supply voltages ‚
– 230 V 50/60 Hz (1, 2)
– 24 V 50/60 Hz (4, 5)
2. Support terminal for PE conductor (3).
3. Analog input for one pressure transmitter 4...20 mA in two-wire technique
(+ = 6, input = 7).
4. Three short-circuit resistant transistor outputs 20 mA for couple relay
(coil connection A1 = + and A2 = –)
– Compressor 1: + = 8 and – = 9.
– Compressor 2: + = 10 and – = 11.
– Compressor 3: + = 12 and – = 13.
10-pole plug for transmission of software and parameters (ISP interface) –
may only be used in connection with 230 V supply, because otherwise a rectifier would be bridged
→ damage to microprocessor!
Software
1. Two of the needed pressure switch points (highest and lowest) must be
set. The others are automatically calculated.
2. The number of compressors is to be set to 2/3.
3. For same size compressors: adjustable cyclic priority change – every
1...250 hours possible - in the case of each periodic change – if the actual
pressure value is not above the switch off pressure values – all compressors first get output releases.
4. For different compressor use: week-switching time mode can be parameterized (set cyclic priority change time via Code 832 to ’0 h’)
→ – 26 switch
points (A...Z) can be used.
All possible priority combinations including total-output lock can be set.
5. Integrated clock with operation reserve (>10 h) in case of power failure.
6. Pressure display combined with display of actual output compressors possible – example: 10.0 bar C1 C_C3.
7. Pressure display combined with display of actual compressor priority
sequence possible – example: 10.0 bar C3
→ C1 → C2. If (during timer
operation) the compressor is shut off, 'C1...C3: _' or 'C1+C2: _' is displayed. In case of an error message, 'C1..C3: l' or 'C1+C2: l' is displayed
– this message may not disappear before the next priority change (can be
eliminated at once by manipulation during timer operation).
8. Pressure display combined with display of actual cycle rest time – in h with
three decimal places possible (number procedure can be observed, if not
in timer operation) – Example: 10.0 bar 1.234 h.
9. Pressure display combined with display of actual time (day-no hh:mm)
possible – example: 10.0 bar 2 08:23h.
10. Display of set lowest and highest pressure switch point possible – example: P<10.50> 9.50 bar.
11. Display of exact time (day-no. hh:mm:ss) possible – example: 1..7
→ 2
08:23:45 h.
General 1.4 Parameter change
Page 6 BOGE Operating instructions trinity
12. Display of software version possible – example: BOGE V 1 – (see also paragraph „Fundamental procedures“ at page 6).
13. Operator friendly automatic branching to necessary sequence settings: as
soon as the cycle time has been set to 0 h, the switching time appears
automatically at first and then the time setting (without a further request for
another code).
14. If the timer function has been selected, the time display blinks when the
operating reserve period has been exceeded after an extended interruption of electricity supply.
To show the displays in 8 – 13, press one of these arrow keys: / repeatedly if necessary.

Number of compressors
and interval period
‚Priority Change’
The control can be used as follows for 2 or 3 compressors. Independently of
this, if the compressors are the same size, a cyclical (cycle time greater than
0) or if the compressors are different, a time-dependent (cycle time to 0) priority time change can be carried out as follows:
1. Input Code 832, as described in ‚Fundamental Procedures’
→ In the dis-
play appears for example: 3 x 002 h, and the left number (here ‚3’) blinks.
2. Use arrow keys / to set the number of compressors to be considered, then use ENTER key to quit
→ now the right number blinks (here
‚002’).
3. Use arrow keys / to set the priority change interval time to the desired value and then use ENTER key to quit
→ the display changes
according to the following criteria:
– If the selected interval time is greater than zero, the display mentioned
in 8.) appears ‚Pressure + Time to next priority change’
– otherwise the text under ‚Switching Times’ appears and as soon as the
switch time input is completed text under ‚Time’ appears.
Switching times
As soon as the cycle time has been set to ‚zero’, the control considers the
switching times, which are input, as described, in the 26 timer channels A...Z.
1. Input code 798, as described in ‚Fundamental Procedures’ – For example:
A 0 00:00h = 123, appears in the display and the left letter (here ‚A’) blinks.
2. Use arrow keys / to select the desired switching channel (A...Z) and
use ENTER key to enable its change
→ now the left number blinks
(here ‚0’ means: this switching canal is not active).
3. Use arrow keys / to input the desired Switching -day -No. (1...7) and
use ENTER key to change to Switching hour, set it and change to
Switching minute and to priority sequence
→
– sequence 000 means ‚Output release will be removed for all compres-
sors from the set time’.
– sequence 123 means: From the switching time onwards ‚Compressor
No. 1 takes the base load, Compressor No. 2 the middle load and
Compressor no. 3 the peak load.
– sequence 312 means: From the switching time onwards ‚Compressor
no. 3 takes the base load, Compressor no. 1 the middle load and Compressor no. 2 the peak load.
4. Use ENTER key to assign the selected Priority sequence to this switching canal
→ the display of the next switching canal blinks (here ‚B’).
5. If all desired switching channels were parameterized the same way (and
the letter of the next canal blinks) you can leave the setting area of the
switching channel by holding down arrow key and pressing ENTER
key . After first parameterization (by setting the interval time to zero),
the display automatically changes to the area described in the section
Time, otherwise the display described in 9.) appears ,Pressure + Day +
Time’.

Time
1. Input code 010 as described in ‚Fundamental Procedures’ → For exam-
ple: 1 00:00:00 h, appears in the display and the left number (here ‚1’)
blinks.
2. Use arrow keys / to select the actual day (Monday = 1, Sunday = 7)
and ENTER key to change time input,
→ now the second number from
the left blinks (here ‚00’).
3. Use arrow keys / to input the actual hour (00...23) and ENTER key
to select minute (00...59), set it and then change to second selection,
set and when the set time (and set day) agrees with the actual time, press
ENTER key
→ the time is set and now the exact time display appears
as described in ,Software point 11’.
