3.16 OPERATION OF THE LUBRICATION SYSTEM OPERATION 3.16.2 SWING CIRCLE PINION LUBRICATION SYSTEM ”SLS” This system works automatically as soon as the engines are run- ning at high idle speed. The ECS System monitors the function of the swing circle lubrica- tion system. Trouble conditions of the lubrication system are indicated through fault messages on ECS display (3).
Legend for illustration Z 21762 (1) Switch, manual actuation of central lubrication sys- tem (2) Switch, manual actuation of swing circle lubrication system (3) ECS display 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. REMARK 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. 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. 246 CAUTION
