#HAPTER CGCM Unit Configuration
Dead Bus Limits
The dead bus limits define the acceptance windows for generator frequency and
voltage used by the CGCM unit when closing the breaker into a dead bus. The
following Configuration tab fields specify the acceptance windows. These fields
set the related tags in the Configuration table.
•
Min Frequency - Tag DeadbusGenFreqLoLimit, expressed in Hertz
•
Max Frequency - Tag DeadbusGenFreqHiLimit
•
Min Voltage - Tag DeadbusGenV_LoLimit, expressed in volts
•
Max Voltage - Tag DeadbusGenV_HiLimit
Rotation
•
Generator – Specifies the generator phase rotation. Configuration table
tag
GenRotABC_ACB_Select stores this value. 0 = ABC, 1 = ACB
•
Bus – Specifies the bus phase rotation. Configuration table tag
BusRotABC_ACB_Select stores this value. 0 = ABC, 1 = ACB

Prior to Host FRN 4.9, regardless of the setting of the
$EADBUS'EN&REQ,O,IMIT parameter, the CGCM unit disables
synchronization when the generator frequency is below 45 Hz.
