Selecting the Input Reference Signal
The TSG-3800 Main shelf provides slots for four Input modules, and it supports up
to 12 separate input reference signals. After you connect the input signals
(described in Making Input Signal
shelf for selecting the signal to be used. This section describes the parameters you
use to select the input signal;
describes how to provision the input signal.
There are several software-settable parameters that affect the selection of the input
signal to be used as the TSG-3800 reference. These include input signal fault
thresholds, frequency and MTIE limits, priority assignments, and synchronous
status message (SSM) settings. The reference selection can be done by priority,
SSM, or by selection of the best input. Software settings also allow for revertive or
non-revertive selection, or manual selection only.
When changing input references, the phase is always reset to zero in software, and
tracking proceeds with the new reference. The TSG-3800 does not follow phase
differences between input signals as this would cause transient frequency
excursions. Phase build-out will not create frequency or MTIE alarms, and will not
affect the output signals.
