The AFE READY status indicator lights up when precharge is completed, the
input contactor K1 is closed, AC power is connected to the AFE, and no faults
are active. The AFE READY status indicator operates independent of the
control method.
The AFE FAULT status indicator lights to indicate that the AFE is in a fault
state.
In an overcurrent situation, the fault that caused the input circuit breaker (Q0)
to trip must be identified and fixed before resetting the breaker.
Modes of Operation
There are three different modes in which the contactor and precharge can be
controlled. The desired control is selected with the REM-AUTO-MAN
selector switch.
1.
AUTO
– Automatic operation that precharges and closes the contactor
when the supply voltage is energized.
a. Set the REM-AUTO-MAN switch to AUTO.
b. Set the OFF-ON-START switch to ON.
