2.3.5 Supply System
Please ensure that you have a good ground installation with a solid, low resistance con-
nection to the battery minus terminal. The connection should be free from dirt, grease,
paint, anodizing, etc.
– MS 6 power consumption at appr. 13 V (vary according to use cases)
– ~ 25 - 30 amps (4 cyl. FDI at 8,500 1/min/200 bar single injection, 1 MSV, 1 elec-
tronic throttle, standard chassis equipment)
– ~ 35 - 40 amps (8 cyl. FDI at 8,500 1/min/200 bar single injection, 2 MSV, 2 elec-
tronic throttle, standard chassis equipment)
– Power consumption of LP-injectors, actuators and coils are to calculate separately.
– The MS 6 power supply is separated into the maintenance of controller and power
stages.
– Ensure controller supply is activated before the power stages.
– The MS 6 is able to control a main relay or even the power box itself via a low side
output.
– As long as the controller is activated, data logging, telemetry and communication is
also ongoing.
– The engine On/Off switch activates the ignition and injection outputs to enable en-
gine start separately from power supply.
