All VFD Fault. Numerous drive faults can cause this general
fault. Reference the TR170 Installation and Operating
manual for a list of fault codes and descriptions.
Condenser fan control will revert to fixed-speed fan
algorithm using remaining fans.
The Latching behavior for this diagnostic is latched in the
drive. When the drive diagnostics are reset this
diagnostic will be cleared in the Symbio 800 controller.
All The inverter peak current of approximately 200% of rated
current was exceeded for 1.5 seconds. Condenser fan
control will revert to fixed-speed fan algorithm using
remaining fans.
The Latching behavior for this diagnostic is latched in the
drive. When the drive diagnostics are reset this diagnostic
will be cleared in the Symbio 800 controller.
This drive alarm may be Trip Locked at the TR170 drive.
If the drive determines that the condition could cause
damage to the drive, the drive protects itself by
generating a Trip Lock that can only be cleared by cycling
power.
All An earth ground fault has resulted in a discharge from the
output phases to ground, either in the cable between the
adjustable frequency drive and the motor or in the motor
itself. Condenser fan control will revert to fixed-speed fan
algorithm using remaining fans. Further operation of the
failed fan is not recommended until measurements to
ground can be taken from the motor leads and the ground
fault removed.
The Latching behavior for this diagnostic is latched in the
drive. When the drive diagnostics are reset this
diagnostic will be cleared in the Symbio 800 controller.
This drive alarm may be Trip Locked at the TR170 drive.
If the drive determines that the condition could cause
damage to the drive, the drive protects itself by
generating a Trip Lock that can only be cleared by cycling
power.
All A short circuit in the motor windings or the motor terminals was
detected. Condenser fan control will revert to fixed-speed fan
algorithm using remaining fans. Further operation of the failed fan
is not recommended until the short circuit is removed.
The Latching behavior for this diagnostic is latched in the
drive. When the drive diagnostics are reset this
diagnostic will be cleared in the Symbio 800 controller.
This drive alarm may be Trip Locked at the TR170 drive.
If the drive determines that the condition could cause
damage to the drive, the drive protects itself by
generating a Trip Lock that can only be cleared by cycling
