Address codes
When two or more SPAU 341 C regulators are
operated in parallel, using the bus connection
modules SPA-ZC 100 as communication de-
vices, certain slave numbers have to be selected
for the regulating modules. The bus connection
modules SPA-ZC 100 can be ordered with fac-
tory configurations, adapted for these specific
regulator applications. The factory configura-
tion can be used when the parallel connected
regulators are working independently, without
being connected to a substation bus system. The
factory configuration of the bus connection
modules assumes that the address codes of the
regulating modules are as follows:
Regulator SPCU 1D50, SPCN 1D56, SPA-ZC 100 _
address codes address codes 1MRS 090704-xx
Plast fiber, xx= Glass fiber, xx=
Regulator 1 10 11 AB DB
Regulator 2 20 21 AC DC
Regulator 3 30 31 AD DD
If the regulators are to be connected to a sub-
station bus system, and the slave address codes
of the factory configuration interferes with the
previously selected codes, the bus connection
modules have to be reconfigured. During con-
figuration phase the monitor registers in sub-
menus 1…7 under register 3 of the SPCU 1D50
module, might be useful. The settings for par-
allel operation are described in detail in the
manual of the automatic voltage regulating
module, SPCU 1D50.
