BOGE – RATIO compressor control for screw compressors
Control Parameterization 1.5
4. Press
↵
-key to overwrite the non-volatile EEPROM as per the blinking
symbol and the corresponding additional parameterization figures, as
described under the respective headlines, appear. Mode '0' does not make
any sense here and is therefore not displayed.
Each time the control is activated by parameterization, afterwards a blinking
time value appears, which is described under
Network independent On-Off-
memory (Auto-Restart). Likewise it can be changed after having selected the
On-Off-memory function.
This value is used as a start delay time, if the control was set to 'Remote' –
via key switch or parameterization – with closed control room contact directly
after a power failure.
If the compressor has to be switched on and off from a control room, the
parameterization has to be set to the 2nd, 3rd or 4th of the following figures:
1. Enter Code 451 as described under parameterization and the display
shows Fig.
c
on the left: The Zero on the top right blinks. This display
means: On/off switching is only possible using the keys of the control
unit.
2. Press
↓
-key to switch to Fig.
d
–
↑
-key to switch back. Digit One and the
symbol 'Remote On-Off' are blinking. This display means: Neither the key-
board of the control unit nor the serial interface but exclusively the Input
for Remote On-Off switch (continuous contact) are used for cut-in and
cut-out (green LED) – see also Switching
Local-Remote via key switch.
3. Press
↓
-key to switch to Fig

–
↑
-key to switch back. Digit Two and the
symbol ‚online‘ are blinking. This display means: the compressor is exclu-
sively switched on or off via the optional serial Interface 'RS485', plug-
able into the control unit – the keyboard and the input for Remote On-Off
switch (continuous contact) are not considered – see also 'Switching
Local-
Remote via key switch' and 'RS485-Bus-Address setting'.
4. Press

-key to switch to Fig
f
–
↑
-key to switch back. Digit Three and the
symbole 'Remote On-Off' and 'online' are blinking. This display means:
The compressor is either switched on or off via the Input for Remote
On-Off switch (continuous contact) or via the optional serial Interface
'RS485', plugable into the control unit, but not by the keys of the control
unit. If the continuous contact is opened, the compressor cut out – see
also Switching Local-Remote via key switch. If the continuous contact is
closed, switching on/off is possible via the serial interface – see also
'Switching
Local-Remote via key switch' and 'RS485-Bus-Address setting'.
5. Press
↵
-key to overwrite the non-volatile EEPROM as per the blinking
symbol and if the above figure is selected the main display reappears.
Otherwise, the figure shown under
Network independent On-Off-Storage
(Auto-Restart) point 3 appears.
If the compressor is set to a Remote-On-Off switch, at the bottom of the main
display the corresponding symbol
is shown. Then the compressor
can only be switched on/ff from Remote. The Emergency Off function is not
concerned. It remains unchanged.
