Power Factor Deviation Trip
Delay
UINT16 RW NV
Default: 20
Range: 1 to 60
Units: seconds
Config CRC
Admin Lock
USB Lock
Backup Mem
PF Deviation Trip Delay time is the time delay from when a Power Factor
trip condition exists to when the motor is tripped.
1060
GF Trip Level Scaled
UINT16 RW NV
Default: 101
Range: 1 to 65535 (RW)
Units: scaled A
Config CRC
Admin Lock
USB Lock
Backup Mem
Ground Fault Trip Level is the value that will generate a trip of the motor
following the Residual Ground Fault Trip Delay time. Scaled by parameter
“I Scale Factor”.
1061
GF Alarm Level Scaled
UINT16 RW NV
Default: 101
Range: 1 to 65535 (RW)
Units: scaled A
Config CRC
Admin Lock
USB Lock
Backup Mem
Ground Fault Alarm Level, if exceeded, will generate a warning following
the Alarm Delay Time in the Protections/General category. Scaled by
parameter “I Scale Factor”.
1062
GF Protection Start Delay
UINT16 RW NV
Default: 0
Range: 0 to 5000
Units: ms
Config CRC
Admin Lock
USB Lock
Backup Mem
Ground Fault Protection Start Delay is a delay at power up to inhibit
raising a ground fault trip condition until this time expires. If the ground
fault trip condition is no longer present when this time expires, no trip will
occur.
1063
GF Trip Debounce
UINT16 RW NV
Default: 1000
Range: 0 to 60000
Units: msec
Config CRC
Admin Lock
USB Lock
Backup Mem
Ground Fault Trip Delay is the time delay before a trip occurs.
1064
GF Protection Inhibit
Current
BOOL RW NV
Default: FALSE
Config CRC
Admin Lock
USB Lock
Backup Mem
Ground Fault Protection Inhibit Current, if selected the GF Inhibit Current
will be used.
1065
GF Protection Inhibit %
UINT16 RW NV
Default: 50
Range: 25 to 100
Units: %
Config CRC
Admin Lock
USB Lock
This parameter will inhibit a Ground Fault trip if the Ground Fault current
exceeds this percentage. The purpose of this is to allow an upstream
control to resolve the issue.
Note: The External Ground Fault Module does not use this current
threshold for inhibit. Instead, the GFM monitors its CT input signal and
when saturated, will inhibit the trip.
