PARAMETER RANGE DESCRIPTION
Main Enable On / Off WhenprogrammedOn,thecontroller’snativesoftwarecontrolsthemain
Main_Enable On / Off contactor when the interlock is enabled; when programmed Off, the
OptionBits1 [Bit 0] contactor is controlled by VCL. Note: With Main Enable programmed Off,
0x306A 0x00 the controller will not be able to open the main contactor in serious fault
conditions and the system will therefore not meet EEC safety requirements.
Main Interlock Type
0 – 1 When set to 0, the main contactor and interlock each work as determined
Main_Interlock_Type 0 – 1 by their respective parameters.
0x386F 0x00 When set to 1, the main contactor will pull in with KSI (like a Type 2
interlock) but the interlock enables/disables drive and engages interlock
braking (like a Type 0 or Type 1 interlock).
Pull In Voltage
0 – 100 % The main contactor pull-in voltage parameter allows a high initial voltage
Main_Pull_In_Voltage 0 – 32767 whenthemaincontactordriverrstturnson,toensurecontactorclosure.
0x303C 0x00 After 1 second, this peak voltage drops to the contactor holding voltage.
Note: The Battery Voltage Compensated parameter (below) controls
whether the pull-in and holding voltages are battery voltage compensated.
Holding Voltage
0 – 100 % The main contactor holding voltage parameter allows a reduced average
Main_Holding_Voltage 0 – 32767 voltage to be applied to the contactor coil once it has closed. This
0x303D 0x00 parameter must be set high enough to hold the contactor closed under all
shock and vibration conditions the vehicle will be subjected to.
Note: The Battery Voltage Compensated parameter (below) controls
whether the pull-in and holding voltages are battery voltage compensated.
Battery Voltage Compensated
On / Off This parameter determines whether the main pull-in and holding voltages
Main_Driver_Battery_Voltage_ On / Off are battery voltage compensated. When set On, the pull-in and holding
Compensated voltages are set relative to the set Nominal Voltage (see Battery Menu,
Main_Driver_Battery_Voltage_ page 64). In other words, the output voltage is adjusted to compensate for
Compensated_Bit0 [Bit 0] swings in battery voltage, so the percentage is relative to the set Nominal
0x302C 0x00 Voltage—not to the actual voltage.
For example, suppose Nominal Voltage is set to 48V and Holding
Voltage is set to 75% (36V) to the output driver. Now suppose the bus
voltage dips to 40V. If Battery Voltage Compensated = On, the output will
still be 36V (Nominal Voltage × Holding Voltage) to the coil. If Battery Volt-
age Compensated = Off, the output will be 30V (Actual Voltage × Holding
Voltage) to the coil.
Interlock Type
0 – 2 Three interlock options are available:
Interlock_Type 0 – 2 0 = interlock turns on with switch 3.
0x300E 0x00 1 = interlock controlled by VCL functions.
2 = interlock turns on with KSI.
Open Delay 0.0 – 40.0 s Applicable only when Interlock Type = 0 or 1. The delay can be set to
Open_Delay 0 – 10000 allow the contactor to remain closed for a period of time (the delay)
0x303F 0x00 after the interlock switch is opened. The delay is useful for preventing
unnecessary cycling of the contactor and for maintaining power to
auxiliary functions that may be used for a short time after the interlock
switch has opened.
