After you power up the BOS as described above,
start-up the BOS as follows:
1
Turn the BOS POWDER TRANSPORT switch
to:
• RECYCLE if you want to send powder in
the BOS hopper to the IRS Used bin, or,
• DISPOSAL if you want to send powder in
the BOS hopper to the waste drum.
2
Press .
3
If the BOS sifter is empty, the BOS turns on
the auger and sifter motors at the bottom of
the hopper and attempts to fill the sifter. If it
can do so in less than 2 minutes, it starts a
RECYCLE or DISPOSAL powder transfer.
4
If the sifter fills in less than 2 minutes, then
• In RECYCLE mode, the BOS enters the
Waiting for IRS state and waits for the IRS to
send it a request for powder.
• In DISPOSAL mode, the BOS enters the
Disposing Powder state and sends powder
to the waste drum until the sifter stays
empty for 2 minutes.
