Condition / Response
The drive has been put into hand mode at the drive
interface. This will cause issues for normal sequences
and operation
A short circuit in the motor windings or the motor
terminals was detected. Compressor operation 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 by setting its persistence to Non-Latching.
This drive alarm may be Trip Locked at the TR200
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.
The condenser fan VFD on circuitX indicates 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 by setting its persistence to Non-Latching.
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.
The condenser fan VFD on circuitX has been put into
hand mode at the drive interface.
Should be for testing only as this will cause issues for
normal sequences and operation.
The condenser fan VFD on circuitX indicates a peak
current of approximately 200% of rated current was
exceeded for 1.5 seconds.
The remaining condenser fans on circuitX will revert
to fixed-speed fan algorithm control.
* 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 by setting its persistence to Non-Latching.
This drive alarm may be Trip Locked at the TR170
drive. If the drive determines that the condition could
