Main Relay(Contactor) Menu
e Main Relay(Contactor) parameters apply to the main contactor in models that use a main
contactor. For other models, the parameters apply to the internal relay. e following table describe
the Main Relay(Contactor) parameters.
MAIN RELAY(CONTACTOR) MENU
PARAMETER VALUES DEFAULT DESCRIPTION
Pull In Voltage 0%-100% 100% Sets the main contactor’s initial voltage when the relay or
contactor driver is rst turned on.
The controller allows a high initial voltage to ensure the relay or
contactor closes. After 1 second, the voltage decreases to the
specied Holding Voltage.
If the Pull In Voltage value is too low to engage the relay or
contactor, the controller generates a Main Contactor Did Not Close
fault.
Holding Voltage 0%-100% 80% Sets the voltage the controller applies to the relay or contactor
coil after the relay closes.
Set Holding Voltage high enough so that the relay or contactor
remains closed under all shock and vibration conditions that the
vehicle is expected to encounter.
Note: Use the Main Contactor Driver PWM eld to monitor the
pull-in and holding voltages. See page 58.
Battery Voltage Compensated On/Off On Species whether the controller adjusts pull-in and holding
voltages to compensate for differences between the nominal and
actual voltages.
Open Delay 0-40s 0s Species how long the main relay should remain closed after the
interlock input has opened.
A delay prevents unnecessary cycling of the relay and maintains
power for other functions that the operator may need to briey
use after the interlock input opens.
