PD4-6624 & PD4-6628 Loop-Powered Flow Rate/Totalizers

Instruction Manual

Batch Control Relay 1

The batch total can be set to count

DOWN

. The batch

MAXIMUM

is the max preset amount that can be batched.

Batching can be set to either manual or automatic operation (

MANUAL

AUTO

). If setting batching to automatic, a

delay before the next batch is started must be programmed. The

PRESET

amount is the value at which the batch will

stop and can be programmed up to the value assigned in the

MAXIMUM

menu. An on and off delay may be set for

batching relays.

Batch Control Relay 2

The

BATCH

option only appears under relay 2 if relay 1 has also been set to batch control. The second relay may be

programmed as a preclose relay or as another batching relay with its own preset amount.
