Fig. 33 Make the "Start-stop automatic" ready to start.
➤ Press the «START» key.
The machine is ready for operation.
The remote contact of the master control system signals the compressed pressure demand
to the controller:
■ The engine is automatically started.
■ The controller switches the machine to LOAD as soon as the required airend discharge
temperature (ADT)* has been attained.
■ If the starting sequence fails or is interrupted by pressing the «EMERGENCY STOP»
push button, the “re-start inhibitor” is activated for 20 seconds. The display shows the re‐
maining time before another start can be attempted.
Further information * For temperature settings, see chapter 2.5.4.
8.6.1.1 Shutting down the machine
When the compressed air demand via the remote contact of the master controller stops, the ma‐
chine shuts down as follows:
1. Machine switches to
run-on phase:
■ The engine runs at IDLE speed.
■ The inlet valve closes.
■ Oil separator tank (OST) is vented.
When there is a new compressed air demand, the machine starts and goes into LOAD mode.
2. The machine switches to
engine run-on:
■ The engine cools down.
■ The engine switches off.
Starting is not possible; the machine switches off and is subsequently restarted.
