Special convey | When this option is enabled, the station’s vacuum | disabled, | disabled |

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 | 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. |
