RATIO
BOGE – RATIO compressor control for screw compressors
These operating instructions contain a description of the RATIO con-
trol system.
BOGE compressors are equipped with a modern control.
RATIO, an integrated control and monitoring concept, with two objectives:
– Energy savings and thus reduction of ongoing costs.
– Prolonging the service life of the compressor due to minimum wear.
All programmed data is stored in a memory module (EEPROM).
Thus the stored information is even available following a power failure.
The BOGE-RATIO control adapts dynamically to the respective operating
conditions. A micro-controller assumes the following three tasks:
1. Automatic selection of the most economical operating mode
The micro-controller calculates the optimum operating mode from the
current operating state and a programmed ideal value, also taking into
account the constant compressor system data (e.g. delivery quantity,
receiver volume, motor switching cycles) as well as the current variables
(e.g. compressed air consumption, supply and non-supply times, pres-
sure increase and decrease speed).
In order to save operating costs, it always strives for the most economical
intermittent operation.
2. Automatic optimization of the motor switching cycles
The micro-controller calculates the optimum number of motor switching
cycles. This protects the drive motor and prolongs the service life of the
plant.
3. Automatic reminder of the maintenance intervals
The microcontroller monitors the maintenance intervals.

Operating/control element Function
– Press the EMERGENCY OFF switch.
The switch engages and interrupts the control
voltage.
All displays are cut off from the power.
After rectifying the fault, unlock the EMERGENCY
OFF switch:
– Turn the EMERGENCY OFF switch a quarter
turn clockwise.
– Quit the display test by pressing OFF key .
– The compressor is ready to use.
Important!
Always switch the compressor off
with the OFF key. Only use EMER-
GENCY OFF in an emergency!
ON key – Press the ON key:
The operating status depends on the network
pressure:
1. Network pressure greater than lower cut-in
pressure. Compressor remains ready.
2. Network pressure lower than lower cut-in
pressure. Compressor starts.
To switch the
compressor on
OFF key If necessary, continues to run in idle until decrease
in system pressure.

Operation/Explanation
[Up] key The key has two functions:
1. It shows the previous information, one step
backward.
2. It normally increases the parameter value.
Display selection
in LC-Display
[Down] key The key has two functions:
1. It shows the next information one step for-
wards.
2. It normally reduces the parameter value.
Display selection
in LC-Display
INFO key – Press the INFO key.
The display shows the main information or fault/
warning message.
Select desired main
information
ENTER key – See parameterization section.For confirmation in
parameterization
