The BOS must be in “Breakout Station” mode
before it can transfer powder to the sifter, then
recycle or dispose of it.
If the BOS is In Standby , make sure the powder
transport switch to on Recycle or Disposal, then
press
. This does the following:
If the sifter is empty (i.e., the level sensor at
the top of the sifter is off ), the sifter motor
runs until sifter is full; i.e., until the level
sensor switches on—or for 2 minutes—
whichever occurs first.
If hopper is empty (i.e., the level sensor on
the hopper is off ), air flows to the left air-slide
until the hopper is full. When hopper is full
(i.e, the level sensor switches on) air flow to
the left air-slide stops.
Transport sequence begins
When sifter is full, the sifter motor shuts off and
transport sequence begins. (The transport
sequence takes about 2 minutes):
1
Sifter air-slide air flow turns on.
2
The transporter fills until its level sensor
switches on.
3
Sifter air-slide air flow turns off
4
Transporter plug-valve closes
5
Transport air turns on, does pressure check
(solids control air is modulated to keep
transport pressure below its maximum limit).
Transport air remains on until low-pressure
setpoint is reached; transport air and solids
control air turn off.
6
Transporter plug-valve opens.
Transport Sequence Complete
When transport sequence is complete, the BOS
checks the sifter level sensor:
`
If sifter level sensor is on (i.e. powder is
present), the transport sequence runs again.
`
If sifter level sensor is off, sifter motor starts
and runs for 2 minutes or until sifter level
sensor switches on—whichever occurs first.
Then transport sequence runs again.
`
If the sifter level sensor stays off after sifter
motor runs for two minutes, the BOS enters
the
In Standby state and remains there until
you press .
