8. Enter the number of loads to control, which is equal
to the number of loads connected to outputs in
step 1.
9. Use the Set S2 Time Delays menu to set the
following associated time delays.
a. Load # Disc E>N:
disconnects loads a programmed time before
transfer from Emergency to Normal. When the
normal source returns, selected loads can be
disconnected from power at different times
before transfer.

b. Load # Rec N>E: post-transfer time delay
reconnects loads a programmed time after
transfer to Emergency. The post-transfer time
delay allows delayed or staggered addition of
selected loads to avoid starting numerous large
motors or other large loads at the same time.
Staggering the loads can minimize voltage dips
as large loads come online.
c. Loads to Add: Enter the number of loads that
have been connected to load control outputs for
pre-transfer disconnect
