•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.
