DB Thermal Warning
A DB Thermal Warning is issued if the predicted future resistor body
temperature is greater than the Max DB resistor temperature x DB
Thermal Warning Percent.
Troubleshooting
– None. DB resistor thermal value has exceeded the
preset threshold of 90% of thermal value.
DB VBus Link Fault
For proper operation, the DB1 monitors parameters from the Drive
internally inside the ArmorStart. If the internal communications to the
drive is lost, then this fault is issued. Since the DB1 can no longer
provide resistor protection, the user must implement logic to open the
input contactor.
Troubleshooting
– Make sure that 3 phase line power and control
power is applied to unit. Attempt to reset fault. If fault persists,
replace control module.
DB Comm Fault
The communications link is monitored continuously. If the DB1 stops
responding, then the MCB issues this fault. Since the DB1 can no
longer provide resistor protection, the user must implement logic to
open the input contactor.
Troubleshooting
– Replace control module.
