MDEC governor assignment
Scope of delivery
Included in the scope of delivery are:
• SAM
• W004 MDEC connector X1 10 m long (15 m and 25 m available as an option).
• W003 (4x2.5 mm
2
) MDEC connector X5 (15 m and 25 m available as an option).
The MDEC governor is protected by a 20 A automatic cutout via cable W003 connector X5.
The PIM modules are wired to a separate 10 A fuse (see MTU wiring diagram).
All control, display and communication signals are in interface cable W004 MDEC connector X1.
CAN 1 is transmitted to the PIM module(s) via conductors 48, 49, 50 and CAN 2 via conductors 51, 52, 53.
A 121 ohm CAN bus terminal resistor must be installed for CAN 1 and CAN 2 respectively at the last PIM module.
Terminal resistors for the MDEC governor are already fitted in cable W004 connector X1.
Digital MDEC inputs/outputs
Inputs
Observe input polarity.
BE1 Stop input
This input is inverted (
line-break protected), i e 24 V DC must always be
applied to BE1 for engine operation.
BE2 Cylinder cutout
The cylinder cutout function is deactivated via this input.
BE3 SISY override
Activating BE8 suppresses all VDS operation shutdown
messages such as “Lube oil pressure too low”. The
corresponding outputs such as Combined alarm red
are still set.
BE4 Fixed speed
The fixed speed function is activated via this input.
BE5 Speed up
Binary input for speed up.
BE6 Speed down
Binary input for speed down.
BE7 Speed droop 2 / desired speed setting
Speed droop can be switched via this input with the
engine running/at a standstill.
Default speed droop setting in the governor:
• 1 = 4%
• 2 = 0%
BE8
Not used.
BE9
Not used.
