Potential Causes and Corrective Actions
Cause
Drive initiated alarm when the InletWaterTempHigh_O
SOP flag is set true and the InletWaterTempHighEn_O
flag is true to enable it. The default is an alarm but it can be
changed to a fault by setting
the InletWaterTempHighWn_O flag to False (true is an
alarm). This is used in the Standard SOP for water-cooled
drives as an alarm.
Action
1. Check physical input connected to SOP flag.
2. Check coolant temperature.
3. Check for flow.
Cause
Drive initiated alarm when the InletWaterTempLow_O
SOP flag is set true and the InletWaterTempLowEn_O flag
is true to enable it. The default is an alarm but it can be
changed to a fault by setting
the InletWaterTempLowWn_O flag to False (true is an
alarm). This is used in the Standard SOP for water-cooled
drives as an alarm.
Action
1. Check physical input connected to SOP flag.
2. Check coolant temperature.
3. Check for flow.
Cause
Drive initiated alarm when the CellWaterTempHigh_O
SOP flag is set true and the CellWaterTempHighEn_O flag
is true to enable it. The default is an alarm but it can be
changed to a fault by setting
the CellWaterTempHighWn_O flag to False (true is an
alarm). This is used in the Standard SOP for water-cooled
drives as an alarm.
Action
1. Check physical input connected to SOP flag.
2. Check coolant temperature.
3. Check for flow.
Cause
Drive initiated alarm when the LowWaterLevelAlarm_O
SOP flag is set true and the LowWaterLevelAlarmEn_O
flag is true to enable it. The default is an alarm and it cannot
be changed. This is used in the Standard SOP for water-
cooled drives as an alarm.
Action
1. Check physical input connected to SOP flag.
2. Check sensor.
3. Check and fill tank.
