Portable Drying/Conveying Systems Chapter 4: Operation 35 of 76
Pressing the SPECIAL CONVEY DISABLED button will activate this dryer feature. 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.
Pressing SPECIAL CONVEY ENABLED will deactivate this feature. 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.) (When this option is enabled, the control
will always continue to convey to the specific station for the specified “convey time”. It
should only be used on those rare occasions when the station demand signal will go off
during the convey period, i.e. sight glass loaders without flappers or cyclone applications.)
Note: For additional information, please contact the Service
Department.
Pressing the LOW LEVEL DISABLED button will activate this dryer feature. When this
option is enabled, the controller issues a “receiver level” alarm if material in the receiver
drains below the level of the receiver’s low-level sensor.
Enable this option if and only if your facility has installed a low-level sensor for this
station’s receiver. At times, you may wish to disable it during operation as a stopgap
measure for dealing with an alarm. Pressing LOW LEVEL ENABLED will deactivate this
feature.
Pressing the NO CONVEY DISABLED button will activate this dryer feature. 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. Pressing NO CONVEY
ENABLED will deactivate this feature.
Pressing the BACK button will take the user to the MACHINE 1 OPERATOR screen. If
the conveying options have already been configured, the user can press the CONVEY
STATUS button to return to the CONVEY STATUS screen.
