M8.1-1 Precharge voltage threshold ”PreChgLv”
This set the Precharge voltage threshold for closing line contactor as a percentage of the battery voltage. The
controller will close the line contactor when capacitor voltage is above the percentage the “Precharge voltage
threshold”.
M8.1-2 Precharge timeout time ”PreChgTO”
This parameter sets the time out for closing line contactor. If capacitor voltage does not reach “Precharge
voltage threshold” within the time out a failure is signalled.
M8.1-3 Digital output 1 pull-in voltage ”LCPlInVl”
It sets the line contactor coil pull in voltage applied for 1s for closing line contactor.
If this parameter is set to its maximum value (i.e. the nominal battery voltage for each Simga2NController size),
the actual battery voltage will be applied, even if it is higher than the nominal battery voltage.
Example:
Nominal battery voltage = 48V, Parameter set to 48V, Actual battery voltage = 52V. The applied voltage is 52V.
Nominal battery voltage = 48V, Parameter set to 47V, Actual battery voltage = 52V. The applied voltage is 47V.
Be aware that this setting has to be set higher or equal to “M8.1-4 Line Contactor Coil holding voltage
”LCHoldVl””. If not a failure F7 S331 will occur.
M8.1-4 Digital output 1 holding voltage ”LCHoldVl”
It sets the line contactor coil holding voltage applied when the line contactor is closed and 1 s of time is elapsed.
If this parameter is set to its maximum value (i.e. the nominal battery voltage for each Simga2NController size),
the actual battery voltage will be applied, even if it is higher than the nominal battery voltage.
Example:
Nominal battery voltage = 48V, Parameter set to 48V, Actual battery voltage = 52V. The applied voltage is 52V.
Nominal battery voltage = 48V, Parameter set to 47V, Actual battery voltage = 52V. The applied voltage is 47V.
M8.1-5 Driver output 1 configuration “Drv1Cfg”
This sets the configuration for Driver Output 1.
• If set to 0, Line Contactor function is assigned to digital output driver 1 (“Pin A15 Contactor 1 o/p
(Line)” of 35 way connector).
The Line contactor will be managed by DMC Controller;
• If set to 1, No function will be assigned to digital output 1. Under this condition, the output is available
to be driven Via CAN. The user is therefore free to map in a CAN message (see [1] for details) the
command to autonomously switch on and off the output.
