3-31 Installing Station Bypass Switches
Figure 31
AEC recommends field-installing a station bypass switch in a
convenient location at each vacuum hopper in series with the
flapper dump Bin Full (
LS ) switch. Check local codes.
Turning off this bypass switch simulates a full machine bin,
cancels a No-Convey alarm, and takes the hopper out of the
loading sequence until the switch is closed. This allows on-the-fly
processing changes and cancels No-Convey alarms.
