5.2.18 FIELD UNDERVOLTAGE DELAY
FUNCTION:
The exciter voltage delay setpoint is the time delay that will elapse after the exciter voltage falls below the pro-
grammed setpoint before the SPM initiates tripping action for field undervoltage (
CHECK EXCITER
)
MOTOR TYPE:
Collector-Ring or Brushless
NOTE:
The
EXCITER VOLTS
option must be enable before this feature can be used.
5.2.19 INCOMPLETE SEQUENCE DELAY
FUNCTION:
If the SPM does not properly complete its starting sequence in the setpoint time, the SPM will trip and display
an in-complete sequence condition.
COLLECTOR-RING: The time setting may be set to a value between 1 and 100 seconds, but not less than the
FCX delay setpoint.
BRUSHLESS: The time setting may be set to a value between 1 and 200 seconds, but not less than the sum of
the FAR delay setpoint and the FCX delay setpoint.
