VFD Condenser Fan
Short Circuit - CktX
where X is “1” or “2”
Circuit Warning Latching*
The condenser fan VFD on circuitX indicates a short
circuit in the motor windings or the motor terminals
was detected.
The remaining condenser fans on circuitX will revert
to fixed-speed fan algorithm control.
Note: 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 by setting its persistence to Non-Latching.
This drive alarm may be Trip Locked at the TR170
d
rive. 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.

Latching*
The inverter peak current of approximately 200% of
rated current was exceeded for 1.5 seconds.
This is a drive enforced lockout.
Note: There is Drive behavior that results from a
Drive Overcurrent where the drive continues to
operate at reduced RPM
* 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
d
rive. 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.

VFD Fault. Numerous vfd faults can cause this
general fault/vfd alarm. When the vfd trips on a
general alarm, the alarm may be latching or non-
latching depending on the vfd settings.
This Symbio™ 800 diagnostic is auto-reset and will
persi
st until the vfd clears the general alarm.

A VFD Fault has occurred four times before the
co
mpressor starts and runs for its minimum on-time.
Numerous vfd faults can cause this general fault/vfd
alarm.
A volatile fault count variable stores the count status.
The count is cleared for any of the following three
conditions:
• Variable speed compressor starts and runs for its
minimum on-time.
• Diagnostic manual reset.
• Controller power cycle.
