If the re-mix timer is disabled, the controller will run only a single, timed mix cycle after each dump of the weigh hopper.

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.

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.

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 and Dump Setup” screen, and then select “Dump Delay”.

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.

Weigh Hopper Dump Cycle

The dump cycle allows the weigh hopper dump valve to cycle, or open and close, a number of times prior to commencing with the next batch cycle. The setting allows from 1 to 9 dump cycles between batches (open and closed cycles).

The normal and default factory setting is 1, meaning the weigh hopper dump valve will open at the end of the weighed batch and close after the batch is discharged into the mixer.

Setting the dump cycle to more than one cycle may be useful when blending high static, dusty material or those that have sticky tendencies. This will cycle the dump valve open and closed to allow any material that may cling to the dump valve.

To enter the dump cycle menu, first enter the Setup menu by pressing the Manufacturer’s icon from the main menu. Enter the password and press enter. Next, press the button marked “Mixer and Dump Setup”. The display will show the “Mixer and Dump Setup” menu. Press the “Dump Cycle” key to enter a dump cycle value and press enter. Please refer to the menu structure tree shown on page 59.
