8.1.5 6sec / 12 sec signal (filling/venting procedure)
The 6sec and 12 sec signals are identical and initiate the filling or venting procedure respectively.
The signal can be repeated after a dwell time.
The 6sec signal is described below.

Description
• The lubricator transmits a permanent output signal (high level) on PIN 4 to signal its readiness for
operation to the controller. This signal must be present without interruption for at least 4 seconds
before a control signal can be transmitted to the lubricator.
• The 4sec 24 V signal (6.9 s ... 12.1 s) can then be transmitted to the lubricator.
• After the signal drops to 0 V, the first motor run of the pump starts and the lubricator pumps
lubricant. The motor running time (ML) depends on the lubricant and the counter
pressure (7 s ... 17 s).
• After the completion of the first pumping sequence the lubricator transmits a
pause signal (P = 0.5 s).
The second motor run follows thereafter. The sequence is repeated 40 times.
The lubricator can process the next signal at the earliest 3 seconds after the completion of the
last motor run (dwell time Tp at least (40 x 17.5) + 6 s).
