Cause(s)
Blower 1 Discharge Pressure ex-
ceeds "Discharge Pressure" High Trip
Setpoint
Blower 1 Suction Pressure falls below
"Suction Pressure" Low Trip Setpoint
Phase A Motor Winding Temperature
exceeds Motor Winding
Temperature High Trip Setpoint
Phase B Motor Winding Temperature
exceeds Motor Winding
Temperature High Trip Setpoint
Phase C Motor Winding Temperature
exceeds Motor Winding
Temperature High Trip Setpoint
Drive End Motor Bearing
Temperature exceeds Motor Bearing
Temperature High Trip Setpoint
Opposite Drive End Motor Bearing
Temperature exceeds Motor Bearing
Temperature High Trip Setpoint
Blower 1 Motor Amps exceeds
"Motor Amps" High Trip Setpoint
Blower 1 Actual Speed is not within
1% of commanded speed.
Fault Contact on Blower 1 VFD is
open indicating Drive Fault
Blower 1 Motor was detected to be
running when not commanded to
run - Supplemental Shutdown out-
put is energized.
Blower 1 external oil pump is com-
manded to run but running confi r-
mation is not received.
Blower 2 Discharge Temperature
exceeds "Discharge Temperature"
High Trip Setpoint
Blower 2 Discharge Pressure ex-
ceeds "Discharge Pressure" High Trip
Setpoint
