7.1.5. Signal 6sec / 12sec (filling-/venting process)
The signals 6sec and 12sec are identical and trigger the filling or venting process. 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 4 s before a control signal can be sent to the FlexxPump 125.
• The 24-V signal 4sec (6.9 s ... 12.1 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 process is repeated 40 times.
• The FlexxPump 125 can process the next signal 3 s after the end of the last motor run at
the earliest (pause time Tp at least (40 x 17.5) + 6 s).
