Run RPM – Change this to the appropriate engine RPM for output operation. Default = 1846
Warm-Up Seconds – Sets the warm-up timer in seconds. Default = 0060
Cool-Down Seconds – Sets the cool-down timer in seconds. Default = 0060
Hz Max Limit – Sets the maximum AC output frequency before the GCM2 activates the AC output fault trip
for overfrequency operation. Default = 0419
Hz Min Limit – Sets the minimum AC output frequency before the GCM2 activates the AC output fault trip
for underfrequency operation. Default = 0381
ACV Hi-Limit – Sets the maximum AC output voltage before the GCM2 activates the AC output fault trip for
overvoltage operation. Default = 3870 (129 Volts, this reading is measured in 30 counts per Volt)
ACV Lo-Limit – Sets the minimum AC output voltage before the GCM2 activates the AC output fault trip for
under-voltage operation. Default = 3030 (101 Volts, this reading is measured in 30 counts per Volt)
Delay Max Hz – Sets the time delay in seconds before the output unlatches due to an over-frequency fault.
Default = 0005
Delay Min Hz – Sets the time delay in seconds before the output unlatches due to an under-frequency
fault. Default = 0007
Delay Hi-ACV – Sets the time delay in seconds before the output unlatches due to an overvoltage fault.
Default = 0002
Delay Lo-ACV – Sets the time delay in seconds before the output unlatches due to an undervoltage fault.
Default = 0007
G-Drive Select – Set to Off or On. Sets GCM2 for Fixed Speed “G-Drive” Engine type. When selected the
Idle RPM, Run RPM Warm-Up Delay and Cool-Down Delay settings are not available as specified for this
engine type. Default = off.
ACV P-Gain – Set the level of Proportional Gain in the AC Voltage regulation. If set too high the AC
Voltage will hunt and be unstable. If set too low the AC Regulation will be poor. Default = 5 (For Build B) or
Default = 2 (For Build A)
ACV Diff-Gain – Set the level of Differential Gain in the AC Voltage Regulation.
Default = 100 (For Build B) or Default = 0 (For Build A)
