6.3.1 General
Regeneration is a process that burns out the soot from the diesel engine's particulate filter.
In normal conditions, regeneration starts automatically and without affecting the rig's per-
formance.
The operator cannot influence the regeneration process. Regeneration is started and
stopped without a message being shown on the display.
6.3.2 Warning of high soot content in the particulate filter.
Warning symbol for high soot level in the particulate filter is displayed when the soot
level reaches 80%.
The warning symbol for Self-holding of drilling lever ceases is shown when the soot
level is above 100%. If the symbol is shown then the engine must be switched off and au-
thorised service personnel contacted.
6.4 Delayed Engine Shutdown - (DES)
6.4.1 Description
When the engine is switched off, it may continue to run at idling speed for a few minutes.
The DES time varies between 1-7 minutes, depending on how hot the injector is.
The purpose of DES is so that the DEF injection system should be able to cool down be-
fore the engine stops. This reduces the risk of damage to the DEF injector.
CAUTION
Risk of injury
Always switch off the engine correctly. See section Stopping the diesel engine for fur-
ther information.
u Do not use the emergency stop to bypass the delayed shutdown period.
u Using the emergency stop system to bypass the delayed shutdown period risks dam-
aging the DEF injector.
Testing the emergency stop system on rigs equipped with DES
The emergency stop system should be tested prior to each shift by activating each respect-
ive emergency stop button. If the engine is hot, there is a risk of damaging the DEF in-
jector. In this case, the engine must be restarted immediately after each emergency stop
button has been depressed.
