Sieve Operation
Powder is supplied to the feed center by HDLV reclaim and virgin powder
transfer pumps. The powder is screened before flowing into the feed hopper.
The sieve is turned on and off with the Touch Screen.
When the sieve is turned off, the reclaim and virgin powder transfer pumps
are disabled.
Reclaim and Virgin Pump Selector Switch Operation
The operation of the Reclaim and Virgin powder transfer pumps are
controlled by separate selector buttons on the Touch Screen.
The transfer pumps are disabled when the sieve is turned off.
Reclaim Transfer Pump Operation
The reclaim pump operates continuously as long as it is turned on and the
sieve is on.
Virgin Transfer Pump Operation
The virgin transfer pump operation is controlled by the level sensors. If the
powder level in the feed hopper falls below the level sensor a delay timer is
started. When the delay timer runs out the virgin powder transfer pump is
started. The pump runs until the powder in the feed hopper reaches the level
sensor, then turns off.
Transfer Pump Manual Purging.
If a transfer pump becomes clogged during operation, purging the pump may
clear it
