8-4 Setting Up Your RGU
Programming the RGU
Using a HIM, GPT, or other programming device, enter the linear
parameter list. The startup procedure below will guide you through
several parameters that need to be configured before operating the
RGU.
Important: The HIM screens shown are only examples. Program
your RGU according to the instructions provided.
Frame Catalog Number [P4]
Enter the frame catalog number of the unit (this should
correspond to the catalog number shown on the data
name plate of the RGU, located below the main control
board.
RGU Control Mode [P5]
Set this parameter to the appropriate setting:
Master Mode (0) Use this setting if this is a master unit in a lineup of multiple RGUs.
Slave Mode (1)Use this setting if this is a slave unit in a lineup of multiple RGUs.
Standalone (2)Use this setting if there are no other RGUs in the lineup (default).
Remote/Local Selector [P8]
Set this parameter to the desired setting (Local Only is default):
Local Only (0)Use this setting for automatic enabling at startup (HIM/GPT not used for enable).
Remote+Local (1)Use this setting for manually enabling the RGU by a HIM or GPT.
AC Line Reactor Inductance [P12]
Determine the total line inductance (the RGU line reactor inductance plus the transformer leakage
inductance).
For line reactor values, refer to the P12 listing in Appendix D. For transformer leakage inductance, use the
following formulas.
Example
An RGU (catalog number 2364FA-MNB) is supplied with a
transformer which has the example nameplate shown.
In Appendix A, we find that the catalog number (2364FA-MNB) indicates the unit is a 460V AC M-code RGU.
The line reactors for this unit are rated at 137 uH as indicated in the component chart in Chapter 5.
To determine the transformer leakage inductance, we can use the 60Hz formula with the information from the
data nameplate.
Add the line reactor inductance to the transformer leakage inductance to determine the value for P12.
P12 = 137uH + 28uH = 165uH (Example only)
