Master switch C555 should be switched on
manually outside the cab.
The master switch can be switched off:
-
Manually (outside the cab)
-
Pneumatically (inside the cab)
Relay G186 is activated when the voltage on pin
4 drops out. Engine stop valve B082 will then be
activated for 60 seconds.
If pressure switch E559 is open, engine stop
valve B082 is not activated.
Switch A can be used to switch off the master
switch pneumatically inside the cab. This also
involves the opening of pressure switch E559.

The electric master switch C669 must be
switched on manually outside the cab.
The electric master switch can be switched off in
the following ways:
-
Manually (outside the cab)
-
Electrically (outside the cab)
-
Electrically (inside the cab)
When switch C667 or C668 is closed, the relay
of the electric master switch is activated, so that
the electric master switch is switched off.
As soon as the electric master switch is
switched off there will be no voltage on the relay.
When the electric master switch is switched off,
the engine continues to operate.
D+ will then be connected to earth.
