2) Grounding cables (EMS ground point/aircraft ground point)
Introduction During installation, a distinction is made between 2 circuits
- Aircraft circuit
- Electronic engine management circuit (EMS circuit).
At the engine start (dynamic condition), the two circuits are connected to
each other through the FUSE BOX.
The routing of the grounding cables (EMS ground and aircraft ground) is
an essential point to be considered when installing the engine electron-
ics.
Components that must not be connected to the aircraft ground or that can
be decoupled from the firewall or in the cockpit:
- ECU (must be installed in the cockpit or an area protected from fire
and water/humidity)
- Regulator A of FUSE BOX (the fuse box must be mounted in the
engine compartment only)
- Starter relay (firewall)
Checks For checking purposes, use a multimeter to carry out a continuity test
between rectifier regulator A and rectifier regulator B in the static condi-
tion.
NOTE: A continuity must not be present. See Fig. 1.
NOTE: EMS ground must be mounted to the regulator plate A
(heat sink of the fuse box) only.
Aircraft ground must be mounted on the regulator plate B
(heat sink of the fuse box) only.
WARNUNG
NOTICE
In the static condition (LANE select SW: "OFF" engine
not running), the EMS ground and the aircraft ground
must not be connected. Components that are connect-
ed to the EMS ground must be installed in such a way
that they are isolated from the aircraft ground.
