TP-6714 4/1058 Section 5 Setup
5.4 Default Settings and Time
Delays
The system can be operated using the factory settings
listed in the following sections.
Use the Setup screens to change the controller time
delays, pickup and dropout settings, inputs, outputs,
and options if necessary.
5.4.1 System Parameters
The system parameter factory settings are shown in
Figure 5-2. The controller voltage and frequency
sensing are factory-set to the default values shown in
Figure 5-3. The voltage and frequency debounce time
delays prevent nuisance transfers caused by brief
spikes and dips in the power supply.

5.4.2 Time Delays
The factory settings for the time delays are shown in
Figure 5-10.
The pre-transfer time delays operate only when both
sources are available. These delays allow time to
disconnect selected loads before transfer. The load
control LED on the user interface lights when the
pre-transfer signal is active. The pre-transfer and post-
transfer time delays overlap the preferred-to-standby
and standby-to-preferred transfer time delays.
