R-TIME
SEC
The ramp time limits the rate of change of the loop output signal and
assists in bumpless loop operation when changing operation mode or loop
parameters. It represents the minimum time required for the output signal
to traverse between saturation points (i.e. from 0 to 100% or vice versa).
HOLD
CTRL
The hold control output feature leaves the output signal at its last value at
the end of a batch (flow should be stopped by the on-off valve).
This allows the control actuator to start a new batch without ramping up
from a fully closed position.
Press
or
to select ENABLE or DISABLE.
HOLD
SEC
The hold control output time determines when the loop control takes over
after a batch starts or resumes. This can provide time for the on-off valve
to open and flow to reach a stable flowrate before the systems resumes
loop control.
BATCH
MODE
Select the required batch operation mode.
•
PRESET
- Preset delivery.
•
ON-OFF
- Manual delivery.
•
RELEASE
- Release flow (loop tuning, only available in
calibration mode).
Press
or
to select either: PRESET, ON-OFF or RELEASE.
Refer to the section Batch Modes for descriptions of each mode.
Note:
The batch control items actually shown in the PARAMS menu are dependent on the
BATCH MODE chosen above. Items that are not relevant for that mode will not appear. Use
the Calibration Menu Tree as a guide to the relevant items.
PERMIS
INPUT
The permissive input feature ensures that a batch will not be allowed until
a permissive contact is closed. A prompt to connect permissive is
displayed. The requirement for the permissive can be enabled or disabled.
For more details, refer to
Press
or
to select ENABLE or DISABLE.
BATCH
LIMIT
The batch limit determines the maximum batch preset value that can be
entered. If a value of zero is entered for this parameter then no limit is
applied.
Enter the value in the engineering units of the batch preset.
