4.2.5 Pre- and Post-Transfer Load
Control Sequence
The pre-transfer and post-transfer load control time
delays operate during transfer between two live
sources, such as during a loaded test sequence or a
loaded exercise. The load control LED lights when the
pre- and post-transfer signals are active.
The pre-transfer load control time delays overlap the
preferred-to-standby and standby-to-preferred time
delays. The longer delay determines the time delay
before transfer.
The timelines in Figure 4-13 illustrate the pre-transfer
time delay sequence using the default settings. (The
default settings for the post-transfer signals are equal to
zero.) The default setting for the preferred-to-standby
time delay is 1 second, and the default setting for the
pre-transfer time delay is three seconds. The time delay
before transfer is equal to the longer time delay, which is
3 seconds. When transferring back to the preferred
source, the standby-to-preferred time delay is 15
minutes. The pre-transfer signal operates during the
final 3 seconds before transfer to the preferred source.
The total time delay before transfer back to preferred
(using the default settings) is 15 minutes.
