• LED Fault and Status Indicators
LED status indicators provide the following indications:
COLOR MARKING DESCRIPTION
GREEN POWER Indicates that the brake chopper power supply is
present
GREEN INTERLOCK Indicates that the external contact is closed when the
interlock is enabled or that the interlock is in the
disabled position
GREEN READY Indicates that no fault condition exists and that the
external interlock is not open
AMBER ACTIVE Indicates that the brake chopper is conducting
AMBER RESET Indicates that the reset circuit is activated
RED OVERTEMP Indicates that the heat sink temperature has reached
95° C and the module has shut down to protect the
transistor.
RED IGBT FAULT Indicates that the module is shut down on short
circuit IGBT detection
• TEST Switch
The TEST switch simulates a DC bus voltage increase; this input is used to set the turn on voltage
and verify transistor and resistor functionality.
