the fact. Refer to Section System Arc Detection of Chapter Operating the Control for information
about this safety feature.
Table 11-17 Cooling Related
Fault Display Type Enable Potential Causes and Corrective Actions
One Blower Not Avail A SOP Cause
Drive initiated alarm set when the OneBlowerLost_O SOP
󹪞ag is set true and the alarm is enabled by
setting OneBlowerLost_EN_O true. On an air cooled drive,
when one of either of the cell blowers or transformer blowers
is not functioning, this is triggered via the SOP. This is part of
the Standard SOP for air cooled drives.
Action
1. Check physical input connected to SOP 󹪞ag.
2. Check for faulty blowers or obstruction.
All Blowers Not Avail F/A SOP Cause
Drive initiated alarm or fault when AllBlowerLost_O SOP
󹪞ag is set true and the alarm/fault is enabled by setting
the AllBlowerLostEn_O 󹪞ag true. This defaults to a fault
with no way to change to a warning with this release. If an
alarm is desired, then the 󹪞ag AllBlowersLostWn_O must
also be set true. This is triggered by the SOP when 2 of 3 cell
banks or both transformer banks of blowers is not function‐
ing. This is primarily used as a trip alarm preceding an over
temperature trip, used on air cooled drives as part of the
Standard SOP.
Action
1. Check physical input connected to SOP 󹪞ag.
2. Check for faulty blowers or obstruction.
Clogged Filters F/A SOP Cause
Drive initiated fault/alarm when the CloggedFilters_O
SOP 󹪞ag is set true and the CloggedFiltersEn_O 󹪞ag is
set true to enable it. The default is a fault. If you desire an
alarm, then the 󹪞ag CloggedFiltersWn_O must be set
true. This is used when an air 󹪝lter becomes clogged to warn
of reduced air 󹪞ow. This is not part of the Standard SOP.
Action
1. Check physical input connected to SOP 󹪞ag.
2. Change 󹪝lter or check for obstruction.
NOTE: On more recent drives a separate PLC controls the cooling. refer to that documentation if this is the case. The
following faults will not occur within the drive if a separate cooling PLC is used.
