To view and change the value of the re-mix timer, refer to the “Mixer and
Dump Setup” menu. All current values for Mixing and Remixing Times
will be shown on this screen. The re-mix timer default value is factory
preset at zero.
5-8-5 Mixer Options
Press the “Timed/Continuous Mixing” key (In the top right hand
corner) when in “Mixer and Dump Setup” screen to set the
following options:
Timed Mixing Option This mode of operation turns the mixer on only
during dumping and during the re-mix time set into the control to jog the
mixer during high level mixer operation.
Continuous Mixing Option This mode of operation turns the mixer on
after initial startup and will continue to run continuously, unless the remix
time is set to jog the mixer during high level mixer operation. This option
is used for sticky materials that tend to bridge and block off the mixer
discharge to the processing machine.
5-8-6 Weigh Hopper Dump Time
The weigh hopper dump time is the amount of time the weigh hopper’s
dump valve remains open to allow weighed material to exit the hopper
and enter the mixer.
To view and change the current weigh hopper dump time settings, enter
the Setup menu and select the “Mixer and Dump Setup” screen. Press
the field next to “Dump Time” to set the operation of the Dump Valve.
The dump timer on the dump valve has a default time of eight (8)
seconds. This time can be adjusted to optimize the blender cycle time.
The timer should be set to close the dump valve shortly after the material
has totally dumped from the weigh hopper. This time can vary due to
material flow characteristics, and the size of the batch that is
programmed into the blender control. Experimentation with this setting
can allow the operator to determine the best cycle for the material being
weighed.
5-8-7 Weigh Hopper Dump Delay Time
The dump delay time is the amount of time from the end of metering the
last ingredient until the start of the actual dump cycle. The start of the
dump cycle is marked by the opening of the weigh hopper dump valve.
This value has a range from 1 second to 999 seconds. To view and
change the current dump delay time, enter the Setup Menu, select “Mixer
