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.

Flexibility

FEATURES

•t Two counter displays; one for permanent preset batch display
and the other for the batch count.

Safety

•t Accepts inputs from Hall-effect pickups, open collector
transistors or dry switch contacts.

•t Presettable batch limit prevents overbatching by not allowing a
batch greater than the specified value to be preset.
•t Preprogrammed 3-second pulse time fail-safe closes the valve in
case of flow signal interruption.
•t Permanent display of preset batch alerts operator of gallons
remaining and also of batch value.

•t Additional open collector output for use with external relays.
•t EEPROM memory preserves all programmed information during
power failure.
•t Rugged aluminum front panel with industrial keypad.
•t Standard: panel mount Optional: meter, desk or wall mount.

•t English annunciators (Batch Ready, Batch, Wash Ready, Wash, and
Hold) inform the operator of the batch condition.

SERVICE

Accuracy

•t Front panel or optional enclosure provides NEMA 4X , IP-65
(watertight and corrosion proof ) protection.

•t Front panel scaling for fast recalibration of meter and/or for
counting in any unit of measure.

•t Field replaceable output Triac.
•t In house stock for prompt replacement.

•t Compensation programming feature provides automatic batch
adjustment for valve shutdown overrun.

COMPLIANCE

•t 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
•t Three-step programming for fast batch change.
•t Wash cycle needs to be preset only once. On manual operation,
the counter reverses and counts up.
