Fault Display Type Enable Potential Causes and Corrective Actions
One Pump Not Available A SOP Cause
Drive initiated alarm when the OnePumpFailure_O SOP
ag is set true and the OnePumpFailureEn_O ag 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 ag.
2. Check for faulty pumps tripped CBs, or obstruction.
Both Pumps Not Available F/A SOP Cause
Drive initiated fault/alarm when the AllPumpsFailure_O
SOP ag is set true and the AllPumpsFailureEn_O ag is
true to enable it. The default is a fault, but it can be changed
to an alarm by setting the AllPumpsFailureWn_O ag
true. This is used in the Standard SOP for water-cooled drives
as a trip alarm.
Action
1. Check physical input connected to SOP ag.
2. Check for faulty pumps tripped CBs, or obstruction.
Coolant Cond > 3 uS A SOP Cause
Drive initiated alarm when
the CoolantConductivityAlarm_O SOP ag is set true
and the CoolantConductivityAlarmEn_O ag 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 ag.
2. Check conductivity level.
3. Check ionizer.
Coolant Cond > 5 uS F/A SOP Cause
Drive initiated fault/alarm when
the CoolantConductivityAlarm_O SOP ag is set true
and the CoolantConductivityAlarmEn_O ag is true to
enable it. The default is a fault, but it can be changed to an
alarm by setting the CoolantConductivityAlarmWn_O
ag true. This is used in the Standard SOP for water-cooled
drives as a trip alarm.
Action
1. Check physical input connected to SOP ag.
2. Check conductivity level.
3. Check ionizer.
