7.6.1— GFI enable
The enable check box will be grayed out for the following conditions:
• Insufficient Security Level.
• Firmware version is not 3.7D or later.
Unit is not a 3-Phase Unit.
•
If enable check box is not grayed out and is checked, the GFI Screen will be similar to Figure 7-1. Otherwise, all edit-
able fields will be grayed out.
7.6.2— GFI Screen's System Generated Fields
The following fields are system generated:
7.6.2.1— Generator Rated Current (RMS Amps)
Derived from system's Voltage and kW parameter settings.
•
• Dependent on Unit Configuration.
7.6.2.2— Generator Average Current (RMS Amps)
Derived from Average Current of all Phases while unit is running.
•
• Dependent on Unit Configuration and load conditions.
7.6.2.3— Generator Gnd + Neutral Current (RMS Amps)
Derived from Unit's Ground Current and Neutral Current while running.
•
Dependent on Unit Configuration and load conditions.
•
7.6.3— GFI Field Editable Parameters
The following fields are field editable by field service technician, site engineer, or similar:
7.6.3.1— Gnd + Neutral Current Threshold (RMS Amps)
FACTORY DEFAULT VALUE = 100% of Generator Rated Current (Unit Configuration Dependent)
•
• This can be changed in field to meet site engineer's recommendation or similar authority.
7.6.3.2— Gnd + Neutral Current Hysteresis (RMS Amps)
• FACTORY DEFAULT VALUE = 1/16 * "Gnd + Neutral Current Threshold" Value
• This can be changed in field to meet site engineer's recommendation or similar authority.
7.6.3.3— Gnd + Neutral Fault Delay(s)
• FACTORY DEFAULT VALUE = 1 Second
This can be changed in field to meet site engineer's recommendation or similar authority.
•
7.6.3.4— Analog Input Channel Assignment (chan_ID)
• FACTORY DEFAULT VALUE = "NULL"
Please see guidelines under the "GENLINK HELP SCREEN INFORMATION" Section before changing this
•
value.
7.6.3.5— Digital Output Function Assignment (chan_ID)
• FACTORY DEFAULT VALUE = "192 (DOF_118)" for H-Panel Controls (as shown in Figure 7-1) or "191
(DOF_117)" for G-Panel Controls
• This output is used to indicate the Ground Fault (GFI).
