D7 Over Voltage 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.

19C Phase Loss – Compressor 1A Immediate 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.

1A0 Power Loss – Compressor 1A Immediate 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.

excessive time or due to a specic set of diagnostic criteria – but w/o
associated latching diagnostics
