Total Reset via Digital Input
The PD4-6624
’s digital input may also be used to reset
the total or grand total using a
control
station.
Total Reset Password Protection
Total and grand total passwords can be set to prevent
resetting the total or grand total unless a password is
entered. Grand total reset can be disabled through
the meter interface, and it can also be permanently
disabled.
Non-Resettable Grand Total
The user can set up the grand total to be non-resettable by
selecting
YES
at the
PERMLOC
menu; see page
details. Once this is done, the grand total can never be reset.
Batch Control Capabilities
The meter can be equipped with two solid-state relays
that may be set up for batch control. Selecting batch
control for relay 1 enables the batching features on the
meter. The top display changes to show the total and the
bottom display changes to show the batch preset. The
function keys also change for batch control functions
such as F1 starts a batch, F2 opens the preset menu to
allow the preset value to be changed, and F3 stops the
currently running batch. Enabling batch control for
relay 1 allows access to the batch menu under relay 2.
The second relay may be programmed as a preclose
relay or as another batching relay with its own preset
amount.
Manual or Automatic Operation
Batching can be set to either manual or automatic
operation.
If set to automatic, then a delay before the next batch
starts must be programmed.
Count Up or Down Batching
The batch total can be set to count up or down.
