keyword=Tech - ramp doors and smoke removal fans operation restored
When we prepared to close the hall, the ramp doors would not close.
Earlier today, we were unable to operate the smoke removal fans. We
suspected the two problems were related, as these systems are
interlocked. We found the fan circuit breakers in a stainless steel
breaker panel on top of the hill, and they were not tripped. We contacted
Paul Powers and Bob Rice and learned that the panel that feeds the panel
on top of the hill is located next to the emergency generator behind the
counting house. That panel is identified as MDP EM, and the breaker that
feeds the fans/doors is breaker 10, which was tripped. Paul Powers reset
the circuit breaker, and everything worked as advertised. Contact me if
you want me to show you where this important breaker is located.
