Criteria
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.
The AFD Drive Fault Relay is open
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/AFD.
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 accelerate fully" diagnostic above and an
aborted start.
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.
The Transition Complete input is shorted before the compressor
was started. This is active for all electromechanical starters.
The "At Speed" input is shorted before the compressor was start-
ed. This is active for solid state starters and AFD.
The Transition Complete input is open with the compressor
motor running after a successful completion of transition. This is
active only for all electromechanical starters
The "At Speed" input was found to be opened with the compres-
sor motor running after successfully obtaining an at speed and
bypassed condition. This is active for solid state starters and
AFD
Compressor current exceeded overload time vs. trip characteris-
tic. For A/C products Must trip = 140% RLA, Must hold=125%,
nominal trip 132.5% in 30 seconds
Detected compressor currents greater than 10% RLA on any or
all phases when the compressor was commanded off. Detection
time shall be 5 seconds minimum and 10 seconds maximum.
On detection and until the controller is manually reset: generate
diagnostic, energize the appropriate alarm relay, continue to en-
ergize the Evap and Cond Pump Outputs, continue to command
the affected compressor off, fully unload the effected compres-
sor. For as long as current continues, perform liquid level and oil
return gas pump control
a. Average of all monitored Line voltages above + 10% of nom-
inal. [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.
a. Average of all monitored Line voltages below - 10% of nomi-
nal or the Under/Overvoltage transformer(s) are not connected.
[Must hold = - 10 % of nominal. Must trip = - 15 % of nominal.
Reset differential = min. of 2% and max. of 4%. Time to trip =
min. of 1 min. and max. of 5 min.) Design: Nom. trip: 60 sec-
onds at less than 87.5%, + or - 2.8% at 200V or + or - 1.8% at
575V, Auto Reset at 90% or greater.
