8.2.4 Control signal 12 seconds
The control signal for 12 seconds triggers the FIL function by the external control.
A total of 40 dispensing operations per pump unit are carried out automatically one
after the other. After a certain pause time, this control signal can be repeated or
another control signal can be sent. The FlexxPump 250/400 DLS reacts only in a
certain operating state to control signals at PIN 2. The operating states are output by
the FlexxPump 250/400 DLS via PIN 4 as high/low levels and must be tapped and
processed accordingly in the PLC.
