5-8-8 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, enter the
diagnostics menu and select item #4 (Dump Valve).
The dump valve diagnostic menu will display (4) options. The first and
second are used as diagnostic tools to open and close the weigh hopper
dump valve manually.
The third option is the dump timer. The dump valve time 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.
5-8-9 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 99 seconds. To view and
change the current dump delay time, enter the Diagnostics Menu, select
option #3 (Dump Valve), and then select option #4 (Dump Delay Time),
The default time is factory set at zero seconds. This delay time is used to
start the mixer prior to dumping the material from the weigh hopper into
the mix chamber of the blender.
