Relays
The two relays can be switched to control the filling stages and to signal fault messages.
They can be assigned to the relevant filling stages of the batch under

Note!
The service life of the relays is specified as 10
5
switching cycles at least. In the case of intensive use,
it is recommended to use the open collector outputs for batch control.
Open collector outputs (optional)
The open collector outputs can be used as status and pulse outputs. If used as status outputs, they
serve to control the filling stages of the batch and to signal fault messages. Counters and the signal
to indicate the end of a batch can be output as pulses.
Universal output - current and active pulse output (optional)
The universal output can be used as a pulse output or analog output. It can output the volume flow
or the volume/mass counter.
Furthermore, the progress of the batch can be output in linear or curve form.
Batch progress
When the progress of the batch is displayed, the output value starts at 20 mA at the beginning of
the batch and moves down linearly until it reaches the lower limit of the current output 0/4 mA at
the end of the batch. The output's lower range limit is issued at the current output if a batch is not
active.

Curve
The current value at the output is 0/4 mA if batching has stopped. The output adopts the current
defined in "Current start value" directly after a batching operation starts. The current value then
moves upwards linearly and reaches the 20 mA current value at a percentage value of the entire
batch quantity, "Start max.", specified in Setup. The current value at the current output then
remains 20 mA until the percentage value of the batch quantity specified in "Stop max." is reached.
The current value is then adjusted downwards linearly to the output value. If a batch is not active,
the lower range limit is output at the current output.
