Fixed and automatic after-run correction
It is recommended to use after-run correction due to system response times. The command to close
the valves is thus given earlier to compensate for the response time. This enables maximum batching
accuracy.
Fixed after-run correction value is the basis. A fixed value can be specified and flow is stopped in
advance by this value.
Automatic after-run correction can be enabled in addition to fixed. It calculates the new correction
value based on the actual measured error of the last batch runs. This ensures precise batching results
permanently.
!
Note!
To ensure that the after-run quantity is kept to a minimum during the first run even if the automatic
after-run correction function is activated (this function requires an initial measurement), it is advis-
able to enter a measured value as the manual after-run correction value, or to teach the device grad-
ually with a small test quantity.
Maximum preset counter
Inputting the maximum preset counter value permitted reduces the risk of incorrect entries. During
operation, if a preset counter value is entered that is greater than the maximum permitted value,
the batch is not started and a message is output.
Batch information
All parameters for displaying and identifying stored batches are saved in batch information. Batches
are identified by means of a user-defined name and a batch number, which is automatically incre-
mented after each batch cycle. The start value of the batch number can also be preset as well as the
current number reset to this value.
Display groups
Display settings
Under Application/Grouping in the Setup menu, select which process values are shown in the dis-
play. For this purpose, 6 display groups are available. A group can be assigned up to 3 values. For a
three-line display, the values are displayed in a smaller font size. A user-defined name can be
assigned to each group (max. 10 characters). This name is displayed in the header. When the device
is delivered, the display groups are preconfigured according to the following table.
Display mode
The display mode is selected in the Display/operation menu. You configure the brightness, contrast
and the switching mode of the display, i.e. whether switching between the display groups takes
place automatically or by pressing a button. In this menu, you can also call up the current values for
data recording (interval, day, month and billing date counter) under "stored values". (For details,
refer to Data logging,

No. of Sums/counter overflow
Counters are limited to max. 8 digits before the decimal point (for counters that require signs, to 7
characters). If the counter reading exceeds this value (overflows), it is reset to zero. The number of
overflows for each counter is recorded on overflow counters. A counter overflow is shown on the
display with the "^" icon. The number of overflows can be called up in the

menu.
Units
The units for scaling and displaying the process variables are configured in the respective submenus
(e.g. the unit for displaying the temperature is configured under Inputs/Temperature). To make
device setting easier, the unit system is selected at the beginning of device commissioning.
