3.17 OPERATION OF THE LUBRICATION SYSTEM OPERATION
270
3.17.2 SWING CIRCLE PINION LUBRICATION SYSTEM ”SLS”
This system works automatically as soon as the engine is run-
ning. The ECS System monitors the function of the swing circle
lubrication system. Trouble conditions of the lubrication system
are indicated through fault messages on ECS display (A).

Manual actuation of the swing circle lubrication
system
Manual actuation of the lubrication system overrides the adjusted
pause time (factory setting 15 minutes). The lubrication cycle
starts after a pressure build up time of 1 to 2 minutes. Thereafter
the monitoring time of 10 minutes starts. The complete lubrication
cycle takes approximately 12 minutes. However, since the swing
circle lubrication system works only during slewing of the super-
structure also the monitoring time elapses only during the slewing
movement. This is the reason why the total monitoring time usu-
ally lasts longer than the adjusted 10 minutes. After elapsing of
the monitoring time the lubrication cycle counter adds one lubrica-
tion cycle to the memory. For display of the cycle counter reading
use the menu control of the ECS system, see page 129 for more
information.
EMARK
The start of a manually actuated lubrication cycle can be
delayed by up to 10 minutes if the system is in the monitoring time
period of a previous automatic lubrication cycle.
CAUTION
If the swing circle lubrication system fails to work for a
period of four hours automatic bucket motion cut off can
happen depending on the installed ECS soft ware. Repair the
system as soon as possible.
