BOGE – RATIO compressor control for screw compressors
Operating/control element
Function
– After unlocking the EMERGENCY OFF switch
and turning on the supply voltage, all enablable
display elements of the control appear at the
same time – including the two indicator lamps.
– If standby was not saved (no Auto-Restart),
this status must first be ended by pressing the
OFF switch O, before the compressor can be
switched on.
– Otherwise it disappears automatically after a
set time and the compressor is on standby
again without touching the controls – see also
Power failure cycle protection.

arrow shaded (as shown here) = automatic
mode selection, right = continuous operation,
the circle left of this means: off here.
The symbol at the bottom left is for
setting
Remote-On-Off and next to it the symbol for
external output enable, next to the right the

online and at the extreme right at the
bottom the symbol for
cut-in-save (Auto-Re-
start). These four symbols only appear when
the respective setting has been made.
