Vacuum supply
The vacuum supply is provided by an electrically operated vacuum pump, which is supplied
by the battery. Starting from the vacuum pump the OKTOPUS
®
GL-R600 is developed as a
dual circuit system. That means, all following vacuum modules, like non-return valve, vac-
uum reservoir, water separator and suction cups are two times present (2 vacuum circles).
At the OKTOPUS
®
GL-R600 the 2 vacuum circles are marked by different colors, one color
per vacuum circuit (usually blue and red). It is to be made sure that only vacuum hoses and
vacuum hose couplings of equal color are interconnected.
When mounted on the crane the OKTOPUS
®
GL-R600 is ready for operation when sufficient
vacuum is provided in both vacuum reservoirs. The current vacuum level is constantly indi-
cated on the two vacuum gauges (Fig. 7).
The green scale range is the
permissible working range from -0.65 bar to -0.9 bar.

Vacuum gauge
During operation the vacuum is monitored by two pressure control devices. If the vacuum is
in both vacuum circles in the working area, the green signal light shines. The OKTOPUS
®
is
ready for use. If the vacuum drops in one or both vacuum circles below the prescribed level
(exceeds the pressure the -0.65 bar mark = red scale range), an alarm is automatically acti-
vated:
⇒
the acoustic alarm sounds,
⇒
the red warning light lights up.
Connect only vacuum hoses respectively vacuum hose couplings of the
same color!
If the alarm is activated stop work immediately and evacuate the hazard
zone, as suctioned elements could suddenly be released.
The alarm remains active until the pneumatic pressure is restored to within
the permitted limits.
