Criteria
The Starter Module did not receive a transition complete signal in the
designated time from its command to transition. The Must Hold time
from the Starter Module transition command is 1 second. The Must Trip
time from the transition command is 6 seconds. Actual design is 2.5
seconds. This diagnostic is active only for Y-Delta, Auto-Transformer,
Primary Reactor, and X-Line Starters.
While in the Starter Dry Run Mode either 50% Line Voltage was sensed
at the Potential Transformers or 10% RLA Current was sensed at the
Current Transformers.
Starter failed to arm or start within the allotted time (15 seconds).
This is a specific starter test where 1M(1K1) is closed first and a check
is made to ensure that there are no currents detected by the CT's. If
currents are detected when only 1M is closed first at start, then one of
the other contactors is shorted.
a. This is a specific starter test where the Shorting Contactor (1K3) is
individually energized and a check is made to ensure that there are no
currents detected by the CT's. If current is detected when only S is
energized at Start, then 1M is shorted. b. This test in a. above applies
to all forms of starters (Note: It is understood that many starters do
not connect to the Shorting Contactor.).
As part of the normal start sequence to apply power to the compressor,
the Shorting Contactor (1K3) and then the Main Contactor (1K1) were
energized. 1.6 seconds later there were no currents detected by the
CT's for the last 1.2 Seconds on all three phases. The test above applies
to all forms of starters except Adaptive Frequency Drives.
Checksum on RAM copy of the Starter LLID configuration failed.
Configuration recalled from EEPROM.
Checksum on EEPROM copy of the Starter LLID configuration failed.
Default configuration loaded into RAM and EEPROM.
The Transition Complete input was found to be opened with the
compressor motor running after a successful completion of transition.
This is active only for Y-Delta, Auto-Transformer, Primary Reactor, and
X-Line Starters. To prevent this diagnostic from occurring as the result
of a power loss to the contactors, the minimum time to trip must be
greater than the trip time for the power loss diagnostic.
The Transition Complete input was found to be shorted before the
compressor was started. This is active for all electromechanical
starters.
Nom. trip: 60 seconds at less than 87.5%,
575V, Auto Reset at 90% or greater for 10 cont secs.
