Configuring Batch Configuring Process MonitorConfiguring OutputsConfiguring Events
Count up Yes • If set to Yes, the total displayed on screen increases from zero to the target
value.
• If set to No, the total displayed on screen decreases from the target value to
zero
• The setting of the Count Up control option affects only the quantity displayed
on screen. It does not affect configuration of presets.
• If the custody transfer application is installed, with either World Area set to
NTEP or World Area set to OIML with batching approved (see Chapter 14),
Count Up is set to Yes and cannot be changed.
Enable end
warning
No • Select Yes to enable the end warning.
• When End Warning is enabled and an end warning value has been entered for
the selected preset, a discrete output can be configured to indicate the end
warning.
• End Warning is a status indicator only, and does not affect valve operation.
• End Warning will remain active until batch completion.
Enable AOC Yes • Select Yes to enable Automatic Overshoot Compensation (AOC).
• When batch AOC is enabled and batch AOC calibration has been performed,
the batch controller compensates for the time required to close the valve.
• If Enable AOC is set to Yes, batch AOC calibration is required to provide data
for the compensation process. To perform batch AOC calibration, see
Section 18.6.
Enable overrun No • Select Yes to enable overrun indication.
• When Overrun is enabled and an overrun value has been entered for the
selected preset, the batch controller produces an overrun alarm when the
batch total exceeds the target by more than the programmed overrun amount.
• Overrun can be assigned to a discrete output. See Section 8.3.2.
Lockout target No • If set to Yes, the current target cannot be changed from the batch operation
screen.
• If set to No, the batch target can be changed from the batch operation screen
when a batch is not running.
Maximum target 1.0000E9 kg If Lockout Target is set to No, enter the maximum target that the operator will be
allowed to set in the batch operation mode.
Ignore source
alarms
No A source alarm is any fault-level alarm. If Ignore Source Alarms:
• Is set to Yes, the batch will not stop for the duration of the alarm timeout.
• Is set to No, the batch is stopped as soon as the alarm condition occurs.
If the custody transfer application is installed, with either World Area set to
NTEP or World Area set to OIML with batching approved (see Chapter 14),
Ignore Source Alarms is set to No and cannot be changed.
Alarm timeout 1 minute This parameter is applicable only if Ignore source alarms is set to Yes.
• Enter the number of minutes, from 1 to 20, for which source alarms will be
ignored.
• If the alarm condition is present when the alarm timeout expires, the current
batch is stopped.
Configure presets
by
% of target Select % of Target or Quantity.
• If set to % of Target, Open Primary, Open Secondary, Close Primary, and End
Warning values are each configured as a percent of target. See Example 2 in
Section 11.6.1.
• If set to Quantity, Open Primary and Open Secondary are each configured as
a quantity at which the valve should open; Close Primary and End Warning
values are each configured as a quantity that is subtracted from the target.
See Example 1 in Section 11.6.1.
• To configure Open Primary, Open Secondary, Close Primary, and End
Warning values, see Section 11.6.
