Shutdown.

Valves N5_S10V2 and N5_S10V4

close. Valve N5_S8V4 then opens for a few
seconds to clear the transporter level sensor
of any adhered powder. Finally valve N5_S2
actuates to open the Right Transporter plug
valve and Valve N5_S5V2 actuates to close
the pinch valve allowing flow to the SLS
system outlet.

SLS system powder transfers

During normal operation, when the SLS system
upper feed hopper sensor is no longer asserted
(the level sensor LED is off ) the SLS system will
call for powder. If the IRS is not in a blend cycle or
transferring powder to another SLS system, it will
respond quickly. If the IRS is blending a powder
batch, it will finish blending before responding.
One transporter load will then be sent. The SLS
system will continue to call for powder until the
SLS system upper feed hopper level sensor is
asserted. As the powder level falls from use, the
top level sensor will no longer be asserted and
the SLS system will call for powder again. Each
transfer follows the following sequence:

1

Transfer Request:

SLS system sends the IRS a

message requesting a transfer.

2

Transfer Acknowledge:

When ready to

transfer, the IRS sends the SLS system an
acknowledge message. The SLS system then
sets its powder control valves to receive the
powder and sends a Valves Complete
message to the IRS.

3

Transfer:

the IRS transfers one transporter

load of powder.

4

Transfer Completion:

When the load of

powder has transferred, the IRS sends the SLS
system a Transfer Complete message.

5

Transfer Completion Acknowledge:

When the

SLS system has reset its powder control
valves, it sends a Valves Reset message to the
IRS.

Each step has a maximum time associated with it.
If the maximum time is exceeded on any one
step, the sequence starts over.
