Figure 38 - Control Devices for AFE in IP20 2500 MCC Style Enclosure
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 over-current 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 automatically 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.
