Diagnostics

Normal Latch Bad Sensor or LLID
Normal Latch Bad Sensor or LLID
Normal Latch Bad Sensor or LLID. Note that if this diagnostic occurs, operational
pumpdown will be performed regardless of the last valid temperature
Normal NonLatch a. Line voltage above + 10% of nominal. [Must hold = + 10 % of
nominal. Must trip = + 15 % of nominal. Reset differential = min. of
2% and max. of 4%. Time to trip = minimum of 1 min. and maximum
of 5 min.) Design: Nom. trip: 60 seconds at greater than 112.5%, + or
- 2.5%, Auto Reset at 109% or less.
Latch a) No current was sensed on one or two of the current transformer
inputs while running or starting (See Nonlatching Power Loss
Diagnostic for all three phases lost while running). Must hold = 20%
RLA. Must trip = 5% RLA. Time to trip shall be longer than guaranteed
reset on Starter Module at a minimum, 3 seconds maximum. Actual
design trippoint is 10%. The actual design trip time is 2.64 seconds.
b) If Phase reversal protection is enabled and current is not sensed
on one or more current xformer inputs. Logic will detect and trip in a
maximum of 0.3 second from compressor start.

Immediate Latch A phase reversal was detected on the incoming current. On a
compressor startup the phase reversal logic must detect and trip in a
maximum of .3 second from compressor start.

Immediate Latch Same as Phase Reversal - Compressor 1A
Immediate Latch Same as Phase Reversal - Compressor 1A
NonLatch The compressor had previously established currents while running
and then all three phases of current were lost. Design: Less than 10%
RLA, trip in 2.64 seconds. This diagnostic will preclude the Phase Loss
Diagnostic and the Transition Complete Input Opened Diagnostic from
being called out. To prevent this diagnostic from occurring with the
intended disconnect of main power, the minimum time to trip must be
greater than the guaranteed reset time of the Starter module.
Note: This diagnostic prevents nuisance latching diagnostics due
to a momentary power loss - It does not protect motor/compressor
from uncontrolled power reapplication. See Momentary Power Loss
Diagnostic for this protection. This diagnostic is not active during the
start mode before the transition complete input is proven. Thus a
random power loss during a start would result in either a "Starter Fault
Type 3" or a "Starter Did Not Transition" latching diagnostic.

Info NonLatch The pumpdown cycle for this circuit was terminated abnormally due to
excessive time or due to a specific set of diagnostic criteria – but w/o
associated latching diagnostics
Info NonLatch Same as Pumpdown Terminated - Circuit 1
Immediate Latch A 30% Current Imbalance has been detected on one phase relative to
the average of all 3 phases for 90 continuous seconds.
Immediate Latch Same as Severe Current Imbalance - Compressor 1A

Immediate Latch Starter has had a loss of communication with the MP for a 15 second
period.
