Dialogue box for switching off the engine
DES Dialogue box
The DES function is activated automatically each time the engine is shut down. When the
DES function shall be activated a dialogue box is shown in the control system. This dia-
logue box cannot be hidden using the ESC key as long as engine status is On . When the
engine has been switched off the box can be hidden with ESC.
If it is necessary to bypass the DES function then this can take place by selecting Force
engine shutdown . The engine will switch off immediately. This is not a recommended op-
tion and should only be used when absolutely necessary. Repeatedly bypassing delayed
shutdown (DES) of the engine may damage the DEF injector. Each time delayed shutdown
is bypassed this is registered in the event log in the rig's control system.
Testing the emergency stop system on a rig equipped with DES
The emergency stop system should be tested prior to each shift by activating each respect-
ive emergency stop button. If engine is hot, there is a risk of damaging the DEF injector. In
this case, the engine must be restarted immediately after each emergency stop button is
depressed.
6.7 Low DEF levels
When the DEF (Diesel Exhaust Fluid) levels become too low a warning symbol, or a com-
bination of warning symbols, is shown at four levels. At the last level, the DEF tank is
empty and the engine is switched off automatically.
