Chapter 2 Warning Messages
X DB GatePwrSupply 177 This warning is for the power supply to the SGCT devices in the
DB cabinet which is being monitored using the TFB and
indicates a problem with the gate power supply associated
with a particular device.
• The device feedback was not correct due to power loss to the gate
driver board. This warning can also appear as a result of another
device fault in the DB cabinet.
• Check the 20V input to the gate driver board. Replace the IGDPS if
necessary.
X DB High Amb Temp 359 Either the DB cabinet ambient temperature exceeds the
warning level or the DB Air flow is less than the specified
warning level.
• Verify the trip and warning settings match the factory
recommended values.
• Check the DB fan, air flow, TFB and DB exhaust temperature sensor
in the DB cabinet.
X DB Low Airflow 362
X DB Temp Sensor 365 The DB temperature sensor is not functioning. A warning is
issued if this happens while running and a fault is issued when
the drive is stopped.
• Check TFB and resistor exhaust temperature sensor in the DB
cabinet.
X DB TFB DataError 366 The DB TFB is not functioning. • Check the TFB in the DB cabinet.
X DBOvrTemperature 364 The DB exhaust temperature has exceeded the DB over
temperature warning level.
• Check the DB fan, air flow, TFB and DB resistor exhaust temperature
sensor in the DB cabinet.
• Verify that the trip and warning settings match the factory
recommended values.
X DBR Overload 367 Braking energy dissipated in the DB resistor exceeded the fault
threshold (in other words, 150% of DB resistor rated energy).
This is a calculated measurement and does not reflect any
physical feedback.
• Verify that the DB resistor parameter settings are correct.
• Verify that the DC current feedback measurement is correct.
X DBSE1Online 420 The drive detected that the diagnostic feedback from this SGCT
device on the DB side did not match the gating pattern.
• After isolating the drive from medium voltage, be sure that the
device, IGDPS power supply and the fiber-optic signals are not
damaged.
• Perform gating test and verify that the gating pattern is correct and
that the drive is receiving proper gating feedback.

X DC Link Range 167 The calculated pu value (P27) of the DC link inductance is less
than the minimum recommended. For 6-pulse SCR the value is
less than 0.8 pu, for 18-pulse SCR the value is less than 0.42 pu
and for PWM rectifier drives the value is less than 0.55 pu.
• Review the DC link nameplate data.
• Review the motor and drive nameplate data and verify that all
parameters were entered properly.
• Contact factory if the above seems OK.
