Assigned to pump 
Number (address) of the pump to which this 
station’s vacuum line is connected. 
No more than 20 stations can be assigned to 
one pump. 
0–7 (0 = not 
assigned) 
Volume fill 
When this option is enabled, the station’s 
vacuum valve closes when material covers the 
station’s proximity sensor or the convey time 
elapses, whichever comes first. When disabled, 
the station’s vacuum valve remains open until 
the convey time has elapsed. 
Enable this option for volume-fill stations and 
disable it for time-fill stations.

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.

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 injection mold uses to make 
each part compared with the capacity of the 
receiver and (b) how important it is to keep your 
injection 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.
