TB1-1&2, and the fuses on the input and outputs sides of the logic
transformer are not blown.
If this contact is not high once power has been applied, refer to the
Troubleshooting Section.

This output indicates that the module’s heatsink is within operating
temperature. If the heatsink gets too hot to safely operate, the
module will stop braking control and this output will go low. Once
the temperature of the heatsink falls to a safe operation temperature,
the module will begin braking action again, and this output will go
high.

This output indicates that the braking power transistor has not failed.
The output is high if the IGBT is operating properly.
If the IGBT shorts during operation, this contact will open, and stay
opened until logic power is cycled.
When this contact goes low, the IGBT is damaged and the unit
needs repair. Contact Bonitron for assistance.

This output indicates that the main power fuse is not blown, and is
ready for braking operation. If the fuse blows, this output will go low.
The module will not be able to brake if the main power fuse is blown.
This output has no function for the 1600A (M14 chassis) unit since
there is no internal fuse.

This output must be high for the module to regulate the DC Bus.
Once this input is high, the Control Ready contacts will close,
indicating that the module is ready for operation.

This bit determines the operation mode of the module. When high,
the module operates in Master or stand-alone mode.
For stand-alone operation, set this bit High for proper operation.

This input will reset any latched faults that have occurred, provided
the fault condition has been removed. Once the faults have been
cleared, the module will return to normal operation.

This bit causes the IGBT to go full on during normal operating
conditions. The Enable input must be engaged, and the unit must
be selected as Master for the input to have an effect.
