The Concrete Batcher provides a large Start ( ) widget on the main screen. Pressing changes the widget to Pause ( ) when the system is processing a mix. Pressing causes the system to display large Resume ( ) and Abort ( ) widgets.
4.8.1 System Process Controls

• Press or press the E-Stop to pause the system when batching has started.
• Press to start the batching process or resume the process when paused.
• Press to abort the batching process when paused.
  NOTE: The system will add a record to the Transaction database with the amount that was batched before the pause widget was pressed.
  NOTE: To deactivate the E-Stop Input, turn the E-Stop Input clockwise.

4.9 Processing a Mix
The Start widget will not display if:

• E-Stop is not pulled out
• Air pressure is low
• Admix (X) is not empty (In either the bottle or the mix)
• Bin/Cement (X) does not have enough material
• In Manual Mode
  NOTE: If Manual Mode is enabled while batching, the screens, tickets and storage may not reflect the actual amount of material processed.

To start the batching process:

1. Press .

NOTE: The system waits until the Conveyor Running input is turned ON. If the Conveyor Running input turns OFF before the Conveyor Runout Time is exceeded, the batch will be paused.
4.9.1 System Discharge Sequence
For a complete breakdown of the System Discharge Sequence, see Section 5.4 on page 36.
Before Discharge Sequence
If the Water Settings are set to Before Discharge, the system will fill all front water before discharging any of the material scales.
During Discharge Sequence
If the Water Settings are set to During Discharge, the system will fill water as it also begins to discharge the material scales, depending on the delay timers configured for each scale.
Tail Water Sequence
Admixtures are either discharged with the front water or with the tail water depending on how they are configured in the Admixture Settings.
4.10 Manual Mode
Once Manual Mode is engaged, the system turns the background gray. While in Manual Mode, the operator can press the Bin 1 – 3 Vibrator, Cement 1 Air or Cement 2 Air and Dust Collector 1 or Dust Collector 2 buttons to toggle the respective outputs on and off. All other outputs are controlled by the switches on the front panel. No other options will be available until Manual Mode is disengaged.

• Turn the manual mode switch to the right to engage manual mode.
• Turn the manual mode switch to the left to disengage manual mode
  NOTE: The system updates the actual weight as weight is dispensed (only if not running a batch). If running a batch, the actual weight dispensed is updated upon exiting Manual Mode.

The system clears the values in each bin/admixture upon the start of the next batch.
4.11 Bin Vibrator/Cement Aeration
If the bin vibrator/cement aeration condition is set to ALWAYS, Bin X Vibrator/Cement X Air Output will be on the entire time Bin X Feed/Cement X Feed Output is on.
If the bin vibrator/cement aeration condition is set to NO FLOW, the system will check if the flow rate is LESS THAN the Min Flow Rate for Bin X/Cement X. If less than, the system will turn on Bin X Vibrator/Cement X Air Output for the remainder of the time Bin X Feed/Cement X Feed Output is on.
If the bin vibrator/cement aeration condition is set to NONE, nothing happens.

5.4 System Discharge Sequence
Water settings allow for toggling between the system discharge settings. See Section 3.4 on page 22 to view and edit the water settings.
5.4.1 Before Discharge Sequence
If the system is set to Before Discharge (Water Settings).

1. The system activates the Water output until the Water Target – (Water Target * Tail Water Percentage) is reached by sensing target pulses minus coast from the water meter. System keeps a portion of the water for Tail Water.

2. If the Admixes are set to begin with Front Water (Admixture Discharge), the system waits until the water starts flowing.
   a. Bottle: activates the Admix X Discharge output until Admix X Bottle Empty input.
   b. Direct: activates the Admix X Fill/Feed output until it senses enough of the target amount (pulses minus coast) from the admix meter on the Admix X Pulse input.

3. Once all front water is in:
   a. The system tares the applicable scales.
   b. The system delays for the Bin/Cement X Delay Time.
   c. The system activates the Bin/Cement X Feed output for the scale until it reaches the product target – free fall weight. The scale will be displayed as a positive value.

4. Once all the Bin/Cement targets are reached:
   a. Dust Collector 1 and 2 outputs are deactivated.
   b. The system displays “Conveyor Runout” for the Conveyor Runout Time and then deactivates the Conveyor output.

5.4.2 During Discharge Sequence
If the system is set to During Discharge (Water Settings).

1. The system tares the applicable scales.

2. The system activates the Water output until the Water Target – (Water Target * Tail Water Percentage) is reached by sensing target pulses minus coast from the water meter. System keeps a portion of the water for Tail Water. It senses pulses-coast from the water meter on the Water Meter input.

3. If Admixes are set to begin with front water, the system waits until the water starts flowing:
   a. Bottle: activates the Admix X Discharge output until Admix X Bottle Empty input
   b. Direct: activates the Admix X Fill/Feed output until it senses enough of the target amount (pulses minus coast) from the admix meter on the Admix X Pulse input

4. The system activates for the Bin/Cement X Delay Time.

5. The system activates the Bin/Cement X Feed output for the scale until it reaches the product target – free fall weight. The scale will be displayed as a positive value.

6. Once all the Bin/Cement targets are reached:
   a. Dust Collector 1 and 2 outputs are deactivated.
   b. The system displays “Conveyor Runout” for the Conveyor Runout Time and then deactivates Conveyor output.

5.4.3 Tail Water Sequence

1. If Admix set to begin with tail water, the system waits until the water starts flowing:
   a. Bottle: activates the Admix X Discharge output until Admix X Bottle Empty input
   b. Direct: activates the Admix X Fill/Feed output until it senses enough pulses-coast from the admix meter on the Admix X Pulse input

2. System activates the Water output until Water Target is reached. It senses pulses from the Water Meter input.

3. System performs the following:
   a. Adds a new record to the Transaction Database table. If Transaction Database ever becomes full, the oldest 25% are automatically deleted.
   b. Prints a batch ticket if Auto Print is Enabled. If Auto Print is Disabled, the operator presses the PRINT button to print a ticket.
