BOGE – RATIO compressor control for screw compressors
Control Parameterization
1.5
If pressure drops in relatively small receiver/pneumatic network volumes must
be avoided at any price, continuous operation can be set as follows – if no
continuous control was parameterized in connection with a single compressor:
1. Enter Code 733 as described under parameterization
→
and the display
shows Fig.
c
on the left.
The shading of the left arrow blinks. This means: automatic power economy
operating mode selection.
2. Press the
↑
or
↓
-key to change to Fig.
d
on the left. (press again to toggle
back...).
The shading of the right arrow blinks. This means: continuous operation.
3. Press
↵
-key to overwrite the non-volatile EEPROM with the blinking sym-
bol, and the main display from the selected symbol appears.
The compressor is set to automatically start an idling phase – in star mode
i.e. without switching on a probably existing ventilator motor – from standby
when the temperature drops to below + 4°C. During this phase in the main
display a thermometer blinks left of the temperature display. The idling phase
is finished as soon as the min. after-running time or + 20°C final compression
temperature are reached.
This anti-freeze function can be switched off as follows:
1. Enter Code 056 as described under parameterization
→
and the display
shows Fig.
c
on the left: the 'curve' left of the thermometer blinks.
This display means: automatic idling phase in frost.
2. Press
↑
or
↓
-key to change to Fig.
d
on the left (press again to toggle
back...) The 3x dotted line left of the thermometer blinks.
This display means: no automatic running phase in frost, shown by means
of the right dash as to the thermometer.
3. Press
↵
-key to overwrite the non-volatile EEPROM with the blinking sym-
bol, and the main display from the selected symbol appears.
