Assigned to pump n Name of the pump to which this station’s
vacuum line is connected.
Special convey When this option is enabled, the station’s
vacuum valve remains open for the convey
time, even if the station is not demanding
material and is indicating that it is full. When
disabled, the station’s vacuum valve opens
when there is demand from the station, and it
remains open until the convey time has elapsed
or material trips the volume-fill proximity switch.
Enable this option if and only if the station has
no flapper.

Closed Loop This option allows material to be conveyed and
processed without being contaminated by
outside influence (such as dust, other materials,
etc.)
Alarm Options
No convey When this option is enabled, the controller
issues a “no convey” alarm if it has repeatedly
attempted to convey material to the station but
the flapper never opened during the dump
delay. (The number of attempts is controlled by
the next setting.)
Usually this option should be enabled. At times,
you may wish to disable it during operation as a
stopgap measure for dealing with an alarm.

# attempts B4 alarm Number of attempts before alarm: the number of
times the controller will attempt to convey
material to a station before it issues a “no
convey” alarm.
The setting for this option depends on (a) how
much material your mold uses to make each
part compared with the capacity of the receiver
and (b) how important it is to keep your mold
from running out of material and shutting down.
A higher setting will give you fewer alarms, at
the risk of emptying the receiver without
warning. A lower setting will give more frequent
alarms, at the risk of disrupting operations
unnecessarily.
