Delay” timer. (See Page 51). Once the dump delay timer has timed out, the controller will
activate the weigh hopper dump valve, initiating the weigh hopper dump cycle.
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 sit 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.)
The level sensor is located on the back wall of the mixer chamber. If the sensor is covered
with material, the indicator light on the back of the sensor will be lit.
Once this sensor is uncovered, the indicator lamp on the back of the level sensor will go out.
This level sensor must be uncovered for approximately 1 - 2 seconds to indicate to the
controller that there is room in the mixing section to accept a batch of material.
When the controller has determined that the mixer is ready for an additional batch of
material, the controller will begin metering material into the weigh hopper assembly.
Recipe Book
In many applications, it is favorable to hold several recipes in the memory of the blending
system. The Slide Gate/Auger blender has provided for this by incorporating the
manufacturer’s recipe book software.
The recipe book is capable of holding 50 different recipes. These may be stored and recalled
by number. During this section of the manual, the operator may wish to revert to the Menu
Tree Diagram in section 3-5 of this manual.
It is important to note that the recipe book only stores and recalls recipes. The blender will
operate on the current recipe only, so a recipe must be recalled from the book to the current
recipe for it to be active.
Each recipe stored in the recipe book may be displayed and/or modified. Only the current
recipe will be blended.
Always verify that the Current Recipe is showing what you want to run, and that the
correct recipe has been downloaded from the book.
The recipe book section contains the following Items:
• Save Running Recipe to the Book
• Load a Stored Recipe from the Book
• Display a Stored Recipe
• Erase One Recipe or the Entire Recipe Book
