External Control
7.1.3. Signal 3sec (two pump strokes)
The signal 3sec triggers two consecutive pump strokes and therefore two lubrication
processes.
The signal can be repeated after a certain pause time.

Description
• The FlexxPump 125 sends a permanent output signal (high level) at PIN 4 to signal
readiness for operation to the controller. This signal must be available uninterruptedly for at
least 3 s before a control signal can be sent to the FlexxPump 125.
• The 24-V signal 3sec (2.9 s ... 3.1 s) can then be sent to the FlexxPump 125.
• After the signal drops to 0 V, the pump’s first motor run starts and the FlexxPump 125
pumps lubricant.
The motor running time (ML) depends on the lubricant and the counter-pressure
(7 s ... 17 s).
• At the end of the first pumping process, the FlexxPump 125 sends a pause signal
(P=0.5 s). Then the second motor run starts.
• The FlexxPump 125 can process the next signal 3 s after the end of the second motor run
at the earliest (pause time Tp at least 38 s).
