RMS in Action at:
OptimERA Inc Alaska U.S.A
Description: Remote site on Sedanka Island.
The RMS-200 remote monitoring board is controlling and monitoring a propane fueled solid
state thermal electric generator (TEG) which powers a remote microwave site on Sedanka
Island. OptimERA provides telephone and internet service to Icicle Seafood's Northern
Victor, which is a fish processing facility in the Bearing Sea. This system hosts phone and
data for the 200+ crew members, including providing critical support to a vessel that would
otherwise have none.

The RMS-200 runs a cron schedule which turns the generator on and off, on a 12 hour cycle.
This powers equipment and charges a battery backup bank which is used when the generator is
not in use. The RMS-200 monitors the generator when it is starting up, when it is running,
the power that it is putting out, the power that is available to the system, the state of
the solenoids, and the state of the propane bank. When the generator starts up, an email is
sent stating that the TEG is starting. If the generator fails to start, a corresponding
email is also generated. When the TEG is at running temperature confirmation of the TEG
state is sent by email.
Four banks of propane run through a solenoid panel with pressure switches before the
solenoids. These switches tell the RMS-200 board what state the banks are in, either
propane or no propane available. When a bank is emtpy an alarm is triggered on the RMS-200
which runs a script that switches the propane bank in use and sends an email alert stating
which bank is empty and the state of the solenoid.
