VFD Compressor
Ground Fault– Cprsr1A
Circuit
Immediate
Shutdown
Latching*
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. Further compressor
operation 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 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.

essure Trip – Cprsr1A
Circuit
Immediate
Shutdown
Latching*
The drive safe stop input was activated. This trip is
the result of a high pressure cutout. The high
pressure switch must reset once the pressure has
dropped and a manual reset must be commanded at
the user interface before the circuit will be allowed to
restart. This diagnostic may require a power cycle to
reset the TR200 drive (Safe Stop) alarm.

diagnostic is latched

diagnostic will be cleared in the Symbio™ 800
controller by setting its persistence to Non-Latching.
This diagnostic may require a power cycle to reset the
