Nominal current max. 120 mA
Instead of common incandescent lamps also LED lamps (-H1 V2, -H2 V2) can be used. In
this case a appropriate pre-resistor must be conducted serial to the LED. An additional re-
sistor parallel to the LED prevents the ECU from detecting an open circuit at this warning
lamp.
CAN INTERFACES – 916 I TYPE C24
Display CAN
916 i TYPE C 24
Two independent Display CAN interfaces are provided for displaying or recording engine
data. When displaying engine data, it must be ensured that data of both CAN interfaces is
used, providing truly redundant data indication or data indication of suitable reliability, con-
sistent with the safety objective of the final application. The proof of consistency with the
safety objective of the final application is the responsibility of the installer.
Maintenance
CAN
To be able to connect the Maintenance CAN A and B with the B.U.D.S Aircraft USB-to-
CAN converter the Maintenance CAN A and B should be connected with two separate
Sub-D DE9 (9-pin) sockets. It is highly recommended to conduct those connectors due to
the fact that the B.U.D.S. Aircraft is a central element when it comes to diagnosis and
maintenance of this engine.
