1F5 Compressor Did
Not Accelerate
Fully
Immediate Latch The starter module did not receive an "Up to Speed"
or "End of Ramp" signal from the SSS within 2.5
seconds after commanding a bypass, or after the
maximum acceleration time had expired, whichever
is longer. This diagnostic only applies to SSS.
Local
EE Compressor Did
Not Accelerate:
Shutdown
Immediate Latch The compressor did not come up to speed (get to
<85%RLA) in the allotted time defined by the
Maximum Acceleration Timer and and the start was
aborted per the starter configuration selected.
Remote
1FA Compressor Did
Not Accelerate:
Transition
Info Latch The compressor did not come up to speed (get to
<85%RLA) in the allotted time defined by the
Maximum Acceleration Timer and a transition was
forced (motor put across the line) at that time. This
applies to all starter types. Note: Since RTHD SSS
has no forced transition capability, this info warning
can be followed with a "Compressor did not accel-
erate fully " diagnostic above and an aborted start.
