OPERATION

3.17.1 OPERATION OF THE AUTOMATIC LUBRICATION SYSTEMS

The shovel is equipped with two automatic lubrication systems:
1. Central Lubrication System (CLS) for lubrication of the attach-
ment bearings, the slewing connection bearing and the slew
gear bearing.
2. Slew ring gear pinion Lubrication System (SLS) for lubrication
of the slew ring teeth.
These systems work automatically as soon as the engine is run-
ning at high idle speed. The slew ring gear lubrication system is
only activated during slewing movement of the superstructure.
The ETM System monitors the function of both lubrication sys-
tems. Trouble conditions of the lubrication systems are indicated
through fault messages on the ETM display.

Electrical components of the Central Lubrication System (CLS) located on the X2 switch
board in the cab base
D3 Pause time relay, factory setting 60 minutes
D4 Monitoring time relay, factory setting 3 minutes
D39 Time relay for switching off the bucket motion if the lubrication system fails to function over a period
longer than 4.2 hours
K28 Relay initiates a fault message if power supply to the lubrication system is interrupted
K30 Relay initiates a fault message if the lubrication cycle is not carried out in the adjusted time period
K136 Relay initiates a fault message if the grease barrel is empty
