“ THRUST BEARIng – PROXIMITY PROBE
CLEARAnCE
”
(Style E and earlier chillers with G, H or J compressors
and Style F and later Chillers with J or H3 Compres-
sors)
The clearance between the compressor high speed thrust
collar and the tip of the Proximity Probe has increased > +10
mils or decreased > -25 mils (for 2 continuous seconds)
from the Reference Position. The minimum allowed
clearance is 23 mils. Therefore, if the Reference position
is < 47 mils, the shutdown will occur when the actual
clearance is < 22 mils.
If equipped with software version C.MLM.01.10.xxx
(and later) or C.OPT.01.10.302 (and later), the operation
is as follows: the clearance is only checked during the
last 20 seconds of “System Prelube”, during “System
Run” and during “Coastdown”. Therefore, the fault is
only detected during those periods. Also, the +10mil
threshold must be exceeded for 2 continuous seconds
(instantaneous with previous software).
this shutdown must be evaluated by a
qualified Service Technician prior to
starting the chiller. Starting the chiller
without this evaluation could result in
severe compressor damage. to prevent
the chiller from starting without the
proper evaluation, restart is inhibited
until the clearance is within acceptable
limits and a special reset procedure is
performed by the Service technician.
the evaluation and reset procedure are
contained in yoRK Service Manual
160.54-M1.

THRUST BEARIng – PROXIMITY PROBE OUT
OF RAngE ”
(Style E and earlier chillers with G, H or J compressors
and Style F and later Chillers with J or H3 Compres-
sors)
The clearance between the compressor high speed thrust
collar and the tip of the Proximity Probe has decreased
to less than 17 mils.
If equipped with software version C.MLM.01.10.xxx
(and later) or C.OPT.01.10.302 (and later), the operation
is as follows: the clearance is only checked during the
last 20 seconds of “System Prelube”, during “System
Run” and during “Coastdown”. Therefore, the fault is
only detected during those periods.
this shutdown must be evaluated by a
qualified Service Technician prior to
starting the chiller. Starting the chiller
without this evaluation could result in
severe compressor damage. to prevent
the chiller from starting without the
proper evaluation, restart is inhibited
until the clearance is 10 to -25
mils of the Reference Position and a
special reset procedure is performed by
the Service technician. the evaluation
and reset procedure are contained in
yoRK Service Manual 160.54-M1.
“ THRUST BEARIng – HIgH OIL
TEMPERATURE
”
(Not applicable to Flash Memory Card version
C.MLM.01.03 and later)
The temperature of the oil in the High Speed Drain Line, as
sensed by the Proximity Probe, has increased to greater
than or equal to 250.0°F.
this shutdown must be evaluated by a
qualified Service Technician prior to
starting the chiller. Starting the chiller
without this evaluation could result in
severe compressor damage. to prevent
the chiller from starting without the
proper evaluation, restart is inhibited
until the temperature decreases to
less than 180.0°F and a special reset
procedure is performed by the Service
technician. the evaluation and reset
procedure are contained in yoRK
Service Manual 160.54-M1.
“
THRUST BEARIng – OIL TEMPERATURE
SEnSOR
”
(Not Flash Memory Card version C.MLM.01.03 and
later)
The temperature of the oil in the High Speed Drain Line,
as sensed by the Proximity Probe, has decreased to less
than 50.0°F during “System Run” or the last 10 seconds
of “System Prelube”.
