Main Contactor Parameters

DRIVERS: MAIN CONTACTOR MENU

ALLOWABLE
RANGE
On / Off When programmed On, the controller's native software controls the main
contactor when the interlock is enabled; when programmed Off, the
On / Off
contactor is controlled by VCL. Note: With Main Enable programmed Off,
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.
0 – 1 When set to 0, the main contactor and interlock each work as determined
by their respective parameters.
0 – 1
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).
0 – 100 % The main contactor pull-in voltage parameter allows a high initial voltage
when the main contactor driver first turns on, to ensure contactor closure.
0 – 32767
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.
0 – 100 % The main contactor holding voltage parameter allows a reduced average
voltage to be applied to the contactor coil once it has closed. This
0 – 32767
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.
On / Off This parameter determines whether the main pull-in and holding voltages
are battery voltage compensated. When set On, the pull-in and holding
On / Off
voltages are set relative to the set Nominal Voltage (see Battery Menu,
page 64). In other words, the output voltage is adjusted to compensate for
swings in battery voltage, so the percentage is relative to the set Nominal
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.
0 – 2 Three interlock options are available:
0 = interlock turns on with switch 3.
0 – 2
1 = interlock controlled by VCL functions.
2 = interlock turns on with KSI.
0.0 – 40.0 s Applicable only when Interlock Type = 0 or 1. The delay can be set to
allow the contactor to remain closed for a period of time (the delay)
0 – 10000
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.
