Chapter 4 CGCM-DLR Unit Configuration
Dead Bus Limits
The dead bus limits define the acceptance windows for generator frequency and
voltage that is used by the CGCM-DLR 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
IMPORTANT
Table 4 provides a guide for how to adjust phase offset for wiring
configurations that are shown in Chapter 2 , Installation . Other wiring
configurations are possible. It is your responsibility to determine and
verify phase offset values for wiring configurations that are not depicted
in this manual.
