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 2sec (1.9 s ... 2.1 s) can then be sent to the FlexxPump 125.
• After the signal drops to 0 V, the pump motor starts running and the FlexxPump 125 pumps
lubricant.
The motor running time (ML) depends on the lubricant and the counter-pressure
(7 s ... 17 s).
• The FlexxPump 125 can process the next signal 3 s after the motor stops running at the
earliest (pause time Tp at least 22 s).
