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
