BOGE base control for screw compressors

Display visualises the second output release mode.
If the actual pressure in this mode drops below the minimum pressure (p
as set in the control, the control unit does not react. The control will not start
the compressor until it is enabled by the external output release device. There-
fore even a net pressure reduction below p
control also switches the compressor automatically off, if the maximum pres-
sure (p ) is exceeded but no warning message is generated. Only when the
max
pressure drops to the lower target pressure value, the external control is prior-
itised again. This mode is recommended if pressure reductions or a standstill
of compressed air production is required within certain periods of time (e.g.
reductions at night or during the weekend).
To set the required output release mode:
4. By means of the Info key
5. Press Enter key
The required output release mode is set. The main display reap-
pears.
Note!
If the compressor is set for an output release device, the bottom of the main
display shows the appropriate symbol
even with external output release: if the upper target pressure value in the
compressor is exceeded, the output will be shut off.
The after-running time determines the time interval for which the compressor
remains in idling after having reached the parameterised switch-off pressure.
1. Enter Code 019, as described under parameterization (see page 12)
and the display shows the figure on the left.
The number 30 blinks. The quotation mark symbol here stands for sec-
onds. A run-out curve is indicated on the two right positions.
2. Press Info key to change the value.
