NOTES:

1. With power applied to Vin, the contacts will close when Vcontrol is greater than

Vcontrol:Close and open when Vcontrol is less than Vcontrol:Open (see Settings Parameters

for values). Connect Vcontrol to Vin to disable logic level control.

2. When the trip limit is exceeded the contacts will open and the Trip indicator line will go

low. The TRIP pin is an open drain. After a trip, Vcontrol needs to be brought low to reset the

contactor.

3. Connect resistor Rx as shown in red to set the current trip level. Choose Rx using the

equation in Settings Parameters. No resistor = 600A.

4. Contactor has two coils. Both are used for pull-in. After approx mately 75 milliseconds,

one coil is electronically removed from the coil drive circuit. The remaining coil supplies low

continuous hold power sufficient for the contactor to meet all of its specified performance

specifications. This provides the lowest coil power possible without the use of PWM

electronics that have been known to cause EMI emissions and/or crosstalk on system

control power.

5. Current Sense: Indicates the current through the main contacts (A2 and A1). The current

sense range is from -600 to +600 amps.
