Pin assignment - External control (PLC)
For electrical connection to the external control (PLC) of a system, the FlexxPump 125
has a 4-pin interface, which is designed as a plug connection with the standard industri-
al M12x1 connection.
The FlexxPump 125 can be switched off completely in Pulse-Control-Mode by swit-
ching off the supply voltage. The settings made are not lost. After reapplying the supply
voltage, the FlexxPump 125 checks itself automatically but only operates after receiving
an input signal from the PLC.
To operate the FlexxPump 125 via an external controller (PLC) in Pulse-Control-Mo-
de, a program corresponding to the communication protocol must be created in the
PLC. A basic flowchart for the command of the FlexxPump 125 can be found in the
appendix (chapter 11.4).
The output signal at PIN 4 can be tapped for further processing (e.g. indicator light
or external control). The maximum permissible output current must not exceed I
max
<
20mA. No inductive load (e.g. relay) may be connected!
After a longer standstill of the FlexxPump 125 the manual execution of the "Quick-
Check" is recommended (chapter 6.3.8). Alternatively, a certain number of donations
can be triggered via the PLC (chapter 8.2).
