IMPORTANT!
Although the Power Transfer Switch stays aligned to
utility if the BBS is shut down so the traffic signals
continue to operate on AC, for safety place the
Manual Bypass Switch in BYPASS to positively
remove power from the PTS and BBS AC input
terminal block.
DANGER
Connecting an inexpensive generator with poor power quality to traffic signal controls can cause the traffic control
conflict monitor to put the intersection in flash. The Generator Transfer Switch simply reroutes the incoming AC from
Utility to Generator at the MBS/PTS. The BBS does not change the AC sine wave (remove noise, etc) unless it goes ON
BATTERY. Generators in the $200 to $500 price range at home improvement stores are not adequate. Generators such as
the Yamaha 2800 that cost more than $1000 are needed for adequate power quality and reliability in industrial use.
DANGER:
Shutting down the BBS2000 does not necessarily disconnect power to the loads.
