The open weigh hopper dump door will allow the material to drop into
the mixer section of the blender. If the dump delay is set, the mixer will
start before the weigh hopper dump will open for the selected time.
The blender will set at rest until the high-level sensor in the mixing
chamber is uncovered to start another weigh cycle. (Unless the Re-Mix
timer is set to a value other than 0 and times out to restart the mixer to
run for another mix cycle.)
5-8-19 Run Mode Displays
Run mode displays are the various messages and indicators offered
to the operator throughout the run mode cycle. Once the blending
system has been properly installed and set up with a valid recipe
entered, the run mode portion of the blending system may be started.
The run mode is started by selecting #1 from the main
menu. After selecting #1 from the main menu, the operator will be given
a small sub menu. See the figure below. This sub menu will allow the
user to select an operating mode. The options on the sub menu are as
follows:
• Weigh Every Batch
• Every Other Batch
• Every Third Batch
• Every Fourth Batch
Select Weighed Batch Interval
1=Every 2=Second 3=Third 4=Fourth
When a recipe is entered and the blender is started up, if any of the
ingredients (slide gate or auger) overshoots by more than 100% of the
target (the target amount to be dispensed), the software triggers the
Metering Overshoot Alarm.
Metering Overshoot - Refer to Manual
This is an indication for the operator to use ‘stroke-limiters’ on the
appropriate slide gate, or use a smaller auger or slower rpm gear motor
to dispense smaller amounts of material.
