Table 92: Safety shutdown messages
Message Description
VSD – GROUND
FAULT
This message is generated when the sum of the three phases of instantaneous input current values
are greater than the shutdown value for a period of 1 second for the given model of drive listed in the
following table.
Drive model Ground current shutdown value
0490B 40 A
When the condition clears, the chiller can be started after the Clear Faults button is pressed.
VSD – HIGH PHASE
A INPUT BASEPLATE
TEMPERATURE
This shutdown occurred because one of the input/rectifier baseplate temperatures exceeded the
shutdown value for the given model of drive listed in the following table.
Drive model High phase a input baseplate temperature shutdown value
0490B 190°F (87.8°C)
The drive's cooling fan(s) and pump(s) continue to run until the temperatures of the input/rectifier
baseplates fall below the shutdown value, and for an additional 20 minutes to ensure overheating of
components does not occur. After the 20 minutes has passed, the drive's cooling fan(s) and pump(s)
are de-energized. When the condition clears, the chiller can be started after the Clear Faults button is
pressed.
VSD – HIGH PHASE
B INPUT BASEPLATE
TEMPERATURE
See the previous message, VSD – HIGH PHASE A INPUT BASEPLATE TEMPERATURE .
VSD – HIGH PHASE
C INPUT BASEPLATE
TEMPERATURE
See the previous message, VSD – HIGH PHASE A INPUT BASEPLATE TEMPERATURE .
VSD – HIGH PHASE
A MOTOR BASEPLATE
TEMPERATURE
The motor/inverter IGBT module temperatures are continuously monitored by the gate driver board
where the highest temperature for each phase is displayed.
Drive model High phase input baseplate temperature shutdown value
0490B 210°F (98.8°C)
The highest temperature is sent to the drive logic board where the temperature is compared against
a shutdown value. If any IGBT module on the motor/inverter exceeds this shutdown value, then this
shutdown occurs. The drive's cooling fan(s) and pump(s) continue to run until the temperatures
of the input/rectifier baseplates fall below the shutdown value, and for an additional 20 minutes
to ensure overheating of components does not occur. After the 20 minutes has passed, the drive's
cooling fan(s) and pump(s) are de-energized. When the condition clears, the chiller can be started
after the Clear Faults button is pressed.
VSD – HIGH PHASE
B MOTOR BASEPLATE
TEMPERATURE
See the previous message, VSD – HIGH PHASE A MOTOR BASEPLATE TEMPERATURE .
VSD – HIGH PHASE
C MOTOR BASEPLATE
TEMPERATURE
See the previous message, VSD – HIGH PHASE A MOTOR BASEPLATE TEMPERATURE .
VSD – HIGH TOTAL
DEMAND DISTORTION
This shutdown indicates the input current to the drive is not sinusoidal. This shutdown occurs if
the Total Demand Distortion (TDD) exceeds 25% continuously for 45 seconds. The displayed TDD is
the sum of the harmonic currents up to the 50th harmonic supplied by the main power to the drive
divided by the Full Load Amps. The chiller can be started after the Clear Fault button is pressed.
