When this option is enabled, the station’s vacuum

disabled

 

valve remains open for the convey time, even if

enabled

 

 

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

disabled,

disabled

 

a “no convey” alarm if it has repeatedly attempted

enabled

 

 

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 before

Number of attempts before alarm: the number of

1–99

3

alarm

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.
