Batch Controller Model CB-30 DESCRIPTION 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. OPERATION 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 singlepoint batching operations. • 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. • Presettable batch limit prevents overbatching by not allowing a batch greater than the specified value to be preset. • 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. • 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. • English annunciators (Batch Ready, Batch, Wash Ready, Wash, and Hold) inform the operator of the batch condition. • Front panel or optional enclosure provides NEMA 4X , IP-65 (watertight and corrosion proof ) protection. • Front panel scaling for fast recalibration of meter and/or for counting in any unit of measure. • Field replaceable output Triac. • In house stock for prompt replacement. • 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. The Model CB-30 batch controller is CE approved and RoHS compliant. Ease of Operation • Three-step programming for fast batch change. • Wash cycle needs to be preset only once. On manual operation, the counter reverses and counts up. Product Data Sheet
