T+RESET= is the reset enable for the total direct (positive)
flow totalizer. When this function is active, the totalizer may
be reset by applying a voltage to the on/off input or via the
keyboard. This may be set to
ON or OFF . If set to off, this
totalizer can not be reset. T+ and T- Reset are continuous
totalizers and are most often not reset.
P+RESET= is the reset enable for the partial direct
(positive) flow totalizer. See the previous function. P+ and
P- Reset are typically reset after a process or batch.
T-RESET= is the reset enable for the total reverse
(negative) flow totalizer. See the previous function.
NOTE: This function is disabled when Batch is set to ON .
P-RESET= is the reset enable for the partial reverse
(negative) flow totalizer. See the previous function.

totalizer values. Push any other key to cancel this
operation. The questions appearing on the display

Programming Functions
displayed when Batch is enabled in the 5-INPUTS menu.
This function is used to set a maximum time for a batch
to start, end, or to stall. If the batch takes too long to
start (flow remains at zero after start) and it exceeds this
value, it will activate an alarm. If the batch is interrupted
for a time that exceeds this value, it will activate an alarm.
If the batch is complete, but the converter senses flow
for a time that exceeds this value, it will activate an alarm.
This function is useful for controlling one or both of the
following conditions:
•
Batch valve is open and flow rate is 0 .
• Batch valve is closed and flow rate different than 0 .
When this alarm is activated, the batch operation is
canceled and the power supply to the valve is removed,
allowing it to close. This may be set from
0 to 6,000
seconds.
