11. DISPLAY SLIP: The slip ratio of the drive belts will be displayed in %
during engine run. The calculation of the ratio is by comparing the
propeller speed measured by the propeller sensor and the engine speed
from the ECU. If this indication is deactivated (N) the OAT will be
displayed instead on the lower left display. Deactivation and activation
see above.
12. MAINSWITCH WARNING: Activation (Y) or deactivation (N) of the
reminder to switch off the main switch. Deactivation and activation see
above.
13. ENABLE FUEL PUMP: The fuel pump of the normal system may be
deactivated for service work (N), normally Y.
Deactivate the fuel pump for any servicing work with empty fuel tank to
prevent the pump from running dry which will cause damage to the pump!
Deactivation and activation see above.
Note: Deactivation only switches off the fuel pump for building up fuel pressure
prior to activating the starter motor (with engine extended, not running and
ignition on).
So in case the fuel pump is not enabled again, the engine will still start and run
but starting may take somewhat longer.
14. PROP BRAKE: Activation (Y) or deactivation (N) of the electrical
propeller brake (Option). Deactivation and activation see above.,
Note: If no electrical propeller brake is installed this function must be
deactivated, otherwise failure messages will be displayed.
Push the selector knob until the DEI-NT beeps twice to leave the set-up
screen.
