PARAMETER RANGE DESCRIPTION
Weld Check Enable On / Off When programmed On, the controller performs a test to make sure the
Weld_Check_Enable On / Off main contactor is open (not welded shut) before it is commanded to close.
OptionBits1 [Bit 2] This test is not performed if this parameter is Off. The main contactor
0x306A 0x00 driver, however, is always protected from short circuits.
Main DNC Check Enable
On / Off When programmed On, the controller performs a test immediately after
Main_DNC_Check_Enable On / Off the main contactor is commanded to close, to make sure the contactor
OptionBits4 [Bit 7] has in fact closed. The test is not performed if this parameter is
0x306D 0x00 programmed Off. The main contactor driver, however, is always protected
from short circuits.
Main DNC Runtime Threshold
0.0 – 200.0 V Sets the threshold used for the ongoing check that ensures the main
Main_DNC_Runtime_Threshold 0 – 12800 contactor remains closed while in operation. The Main DNC Runtime
0x3032 0x00 Threshold is the maximum voltage difference between the Keyswitch and
Capacitor voltages. When the voltage difference is above this threshold,
and the battery current is low, a Main Did Not Close fault will be set.
Setting this parameter lower will increase the sensitivity of the fault
detection. Setting this parameter too low may cause false fault trips due
to normal voltage drops between the keyswitch and capacitor voltages.
Setting this parameter = 0 V will disable the Main Did Not Close fault
check.
Precharge Enable
On / Off Turns the precharge feature on and off. Precharge provides a limited

OptionBits2 [Bit 6] contactor is closed. This decreases the arcing that would otherwise occur
