The Model CB-30 batch controller is especially designed for use in concrete plants to batch water into the concrete mix. Unlike ordinary batch controllers, the CB-30 allows the operator to quickly set and run an exact batch, which includes a preset wash
amount and valve overrun compensation. It also allows for manual operation to override normal presets.

The CB-30 is designed to work mainly with the Badger Meter® Turbo/Butterfly Valve system. The pulse signal coming from the meter’s pulse transmitter is scaled to US gallons or other units of measure. Once the Batch and Wash cycles are set by the operator, a START command energizes the valve solenoid, opening the valve. The CB-30 counts down from the batch valve to a number equal to the total desired batch less the wash amount, and then closes the valve. The operator presses START again and the wash amount runs, completing the batch. The CB-30 is also suitable for other single-point batching operations.


Features:
• Presettable batch limit prevents overbatching.
• Preprogrammed 3-second pulse time fail-safe closes the valve in case of flow signal interruption.
• Permanent display of preset batch alerts operator of gallons remaining and also of batch value.
• English annunciators (Batch Ready, Batch, Wash Ready, Wash, and Hold) inform the operator of the batch condition.
• Front panel scaling for fast recalibration of meter and/or for counting in any unit of measure.
• Compensation programming feature provides automatic batch adjustment for valve shutdown overrun.
• Manual override allows operator to manually dispense water or add to the preset batch.
• Three-step programming for fast batch change.
• Wash cycle needs to be preset only once. On manual operation, the counter reverses and counts up.
• Two counter displays; one for permanent preset batch display and the other for the batch count.
• Accepts inputs from Hall-effect pickups, open collector transistors or dry switch contacts.
• Additional open collector output for use with external relays.
• EEPROM memory preserves all programmed information during power failure.
• Rugged aluminum front panel with industrial keypad.
• Standard: panel mount Optional: meter, desk or wall mount.
